www.uce3.berkeley.edu INFORMATION STRATEGIES AND ENERGY CONSERVATION BEHAVIOR: A META-ANALYSIS OF EXPERIMENTAL STUDIES  

E-Print Network (OSTI)

Strategies that provide information about the environmental impact of activities are increasingly seen as effective to encourage conservation behavior. This article offers the most comprehensive meta-analysis of information based energy conservation experiments conducted to date. Based on evidence from 156 published field trials and 525,479 study subjects from 1975 to 2012, we quantify the energy savings from information based strategies. On average, individuals in the experiments reduced their electricity consumption by 7.4%. Our results also show that strategies providing individualized audits and consulting are comparatively more effective for conservation behavior than strategies that provide historical, peer comparison energy feedback. Interestingly, we find that pecuniary feedback and incentives lead to a relative increase in energy usage rather than induce conservation. We also find that the conservation effect diminishes with the rigor of the study, indicating potential methodological issues in the current literature.

Dynamic Analysis of Learning in Behavioral Experiments  

E-Print Network (OSTI)

Understanding how an animal’s ability to learn relates to neural activity or is altered by lesions, different attentional states, pharmacological interventions, or genetic manipulations are central questions in neuroscience. Although learning is a dynamic process, current analyses do not use dynamic estimation methods, require many trials across many animals to establish the occurrence of learning, and provide no consensus as how best to identify when learning has occurred. We develop a state–space model paradigm to characterize learning as the probability of a correct response as a function of trial number (learning curve). We compute the learning curve and its confidence intervals using a state–space smoothing algorithm and define the learning trial as the first trial on which there is reasonable certainty (?0.95) that a subject performs better than chance for the balance of the experiment. For a range of simulated learning experiments, the smoothing algorithm estimated learning curves with smaller mean integrated squared error and identified the learning trials with greater reliability than commonly used methods. The smoothing algorithm tracked easily the rapid learning of a monkey during a single session of an association learning experiment and identified learning 2 to 4 d earlier than accepted criteria for a rat in a 47 d procedural learning experiment. Our state–space paradigm estimates learning curves for single animals, gives a precise definition of learning, and suggests a coherent statistical framework for the design and analysis of learning experiments that could reduce the number of animals and trials per animal that these studies require.

Sensitivity analysis techniques for models of human behavior.  

SciTech Connect

Human and social modeling has emerged as an important research area at Sandia National Laboratories due to its potential to improve national defense-related decision-making in the presence of uncertainty. To learn about which sensitivity analysis techniques are most suitable for models of human behavior, different promising methods were applied to an example model, tested, and compared. The example model simulates cognitive, behavioral, and social processes and interactions, and involves substantial nonlinearity, uncertainty, and variability. Results showed that some sensitivity analysis methods create similar results, and can thus be considered redundant. However, other methods, such as global methods that consider interactions between inputs, can generate insight not gained from traditional methods.

Accommodating complexity and human behaviors in decision analysis.  

Science Conference Proceedings (OSTI)

This is the final report for a LDRD effort to address human behavior in decision support systems. One sister LDRD effort reports the extension of this work to include actual human choices and additional simulation analyses. Another provides the background for this effort and the programmatic directions for future work. This specific effort considered the feasibility of five aspects of model development required for analysis viability. To avoid the use of classified information, healthcare decisions and the system embedding them became the illustrative example for assessment.

Productivity index and field behavior: a case study  

E-Print Network (OSTI)

This study is an investigation of different factors' phics. influence on the productivity index and its behavior. The objectives of this research are (1) to develop an overview of how different factors influence the productivity index', and (2) to explain the irrational behavior of the productivity index in a case study presented. The problem has its origin in a field in north Africa, where irrational behavior of the productivity index (PI) has made it difficult to forecast the field performance. By irrational behavior we meant that the PI ants the opposite of what is expected. Normally we think PI will increase when the production oil rate of the field increases, at the same pressure drawdown. Or for the same well, PI should be constant over time. In some wells in this particular field we can see the P1 increase as production oil rate decreases and vice versa. Numerical simulation was used to simulate the influence different factors had on the productivity index, and to match wellness PI's with calculated PI's from field data in the case study. An overview of which factors can cause the P1 to go in unexpected directions is presented. Finally the theory obtained about the PI behavior is linked to the case study, and the E6incon-ect'' behavior of the PI is explained. It was shown that transient flow and two-phase flow are the two main reasons for the productivity index to decrease as production oil rate increases. It was also shown that dual porosity, non-Darcy flow, permeability changes, formation compressibility, and skin affect the length of the transient flow period and the magnitude of the difference between transient PI and pseudo steady state (PSS) PI. The behavior of the PI in the field case presented is explained by the transient flow effect and bad test data.

An analysis of heating fuel market behavior, 1989--1990  

SciTech Connect

The purpose of this report is to fully assess the heating fuel crisis from a broader and longer-term perspective. Using EIA final, monthly data, in conjunction with credible information from non-government sources, the pricing phenomena exhibited by heating fuels in late December 1989 and early January 1990 are described and evaluated in more detail and more accurately than in the interim report. Additionally, data through February 1990 (and, in some cases, preliminary figures for March) make it possible to assess the market impact of movements in prices and supplies over the heating season as a whole. Finally, the longer time frame and the availability of quarterly reports filed with the Securities and Exchange Commission make it possible to weigh the impact of revenue gains in December and January on overall profits over the two winter quarters. Some of the major, related issues raised during the House and Senate hearings in January concerned the structure of heating fuel markets and the degree to which changes in this structure over the last decade may have influenced the behavior and financial performance of market participants. Have these markets become more concentrated Was collusion or market manipulation behind December's rising prices Did these, or other, factors permit suppliers to realize excessive profits What additional costs were incurred by consumers as a result of such forces These questions, and others, are addressed in the course of this report.

Scoping studies: behavior and control of lithium and lithium aerosols  

Science Conference Proceedings (OSTI)

The HEDL scoping studies examining the behavior of lithium and lithium aerosols have been conducted to determine and examine potential safety and environmental issues for postulated accident conditions associated with the use of lithium as a fusion reactor blanket and/or coolant. Liquid lithium reactions with air, nitrogen, carbon dioxide and concretes have been characterized. The effectiveness of various powder extinguishing agents and methods of application were determined for lithium-air reactions. The effectiveness of various lithium aerosol collection methods were determined and the volatilization and transport of radioactive metals potentially associated with lithium-air reactions were evaluated. Liquid lithium atmosphere reactions can be safely controlled under postulated accident conditions, but special handling practices must be provided. Lithium-concrete reactions should be avoided because of the potential production of high temperatures, corrosive environment and hydrogen. Carbon microspheres are effective in extinguishing well established lithium-air reactions for the lithium quantities tested (up to 10 kg). Large mass loading of lithium aerosols can be efficiently collected with conventional air cleaning systems. Potentially radioactive species (cobalt, iron and manganese) will be volatilized in a lithium-air reaction in contact with neutron activated stainless steel.

Multi analysis of the effect of grain size on the dynamic behavior of microalloyed steels  

SciTech Connect

This study presents some aspects of multiscale analysis and modeling of variously structured materials behavior in quasi-static and dynamic loading conditions. The investigation was performed for two different materials of common application: high strength microalloyed steel (HSLA, X65), and as a reference more ductile material, Ti-IF steel. The MaxStrain technique and one pass hot rolling processes were used to produce ultrafine-grained and coarse-grained materials. The efficiency and inhomogeneity of microstructure refinement were examined because of their important role in work hardening and the initiation and growth of fracture under tensile stresses. It is shown that the combination of microstructures characterized by their different features contributes to the dynamic behavior and final properties of the product. In particular, the role of solute segregation at grain boundaries as well as precipitation of carbonitrides in coarse and ultrafine-grained structures is assessed. The predicted mechanical response of ultrafine-grained structures, using modified KHL model is in reasonable agreement with the experiments. This is a result of proper representation of the role of dislocation structure and the grain boundary and their multiscale effects included in this model.

Managerial Coaching Behavior and Employee Outcomes: A Structural Equation Modeling Analysis  

E-Print Network (OSTI)

During the last two decades, managerial coaching has become increasingly popular in organizations. Despite its popularity, there is a paucity of empirical evidence in the study of managerial coaching outcomes. The purpose of this study was to examine the relationships between perceived managerial coaching behavior and employee self-reported affective and performance-related outcomes based on perceptions of selected organization employees. Three theories, path-goal leadership, career motivation, and organization support, were used to frame the hypothesized conceptual model of managerial coaching outcomes for the current study. The systematic review of relevant literature identified satisfaction with work, role ambiguity, satisfaction with manager, career commitment, job performance, and organization commitment for the potential outcomes of managerial coaching. A 36-item survey including seven existing instruments was utilized to collect data. An estimation of the readability level for the survey was Flesh-Kincaid Grade Level 7.1. The survey was sent electronically to all employees in the selected government organization. The sample included 431 respondents representing a population of 1,399 employees. Descriptive statistics, principal component analysis, Cronbach‘s alpha estimates for reliability, correlation analysis, two-step modeling techniques for structural equation modeling, and Sobel tests were the analysis methods used in the study. The results of the analyses indicated that the hypothesized conceptual model was adequately supported by the empirical data of the study sample (?2/df = 3.53; CFI = .91; IFI = .91; RMSEA = .08). The further investigations suggested that managerial coaching had a direct impact on employee satisfaction with work and role clarity and an indirect impact on satisfaction with work, career commitment, job performance, and organization commitment. Role clarity, as a direct outcome of managerial coaching, influenced job performance—such mediation was consistent with the hypothesized model for the study. The hypothesized model had clear and comprehensive illustrations of how managerial coaching affects work and organization-related variables, satisfaction with work, role clarity, career commitment, job performance, and organization commitment. This study provides empirical support to the proposed benefits of managerial coaching in organizations, and enhances the selected theories by offering additional empirical support to them.

Chemical systems for improved oil recovery: Phase behavior, oil recovery, and mobility control studies  

SciTech Connect

Selected surfactant systems containing a series of ethoxylated nonionic surfactants in combination with an anionic surfactant system have been studied to evaluate phase behavior as well as oil recovery potential. These experiments were conducted to evaluate possible improved phase behavior and overall oil recovery potential of mixed surfactant systems over a broad range of conditions. Both polyacrylamide polymers and Xanthan biopolymers were evaluated. Studies were initiated to use a chemical flooding simulation program, UTCHEM, to simulate oil recovery for laboratory and field applications and evaluate its use to simulate oil saturation distributions obtained in CT-monitoring of oil recovery experiments. The phase behavior studies focused on evaluating the effect of anionic-nonionic surfactant proportion on overall phase behavior. Two distinct transition behaviors were observed, depending on the dominant surfactant in the overall system. The first type of transition corresponded to more conventional behavior attributed to nonionic-dominant surfactant systems. This behavior is manifested by an oil-water-surfactant system that inverts from a water-external (highly conducting) microemulsion to an oil-external (nonconducting) one, as a function of temperature. The latter type which inverts in an opposite manner can be attributed to the separation of the anionic-nonionic mixtures into water- and oil-soluble surfactants. Both types of transition behavior can still be used to identify relative proximity to optimal areas. Determining these transition ranges provided more insight on how the behavior of these surfactant mixtures was affected by altering component proportions. Efforts to optimize the chemical system for oil displacement experiments were also undertaken. Phase behavior studies with systems formulated with biopolymer in solution were conducted.

Quantitative study of rectangular waveguide behavior in the THz.  

SciTech Connect

This report describes our efforts to quantify the behavior of micro-fabricated THz rectangular waveguides on a configurable, robust semiconductor-based platform. These waveguides are an enabling technology for coupling THz radiation directly from or to lasers, mixers, detectors, antennas, and other devices. Traditional waveguides fabricated on semiconductor platforms such as dielectric guides in the infrared or co-planar waveguides in the microwave regions, suffer high absorption and radiative losses in the THz. The former leads to very short propagation lengths, while the latter will lead to unwanted radiation modes and/or crosstalk in integrated devices. This project exploited the initial developments of THz micro-machined rectangular waveguides developed under the THz Grand Challenge Program, but instead of focusing on THz transceiver integration, this project focused on exploring the propagation loss and far-field radiation patterns of the waveguides. During the 9 month duration of this project we were able to reproduce the waveguide loss per unit of length in the waveguides and started to explore how the loss depended on wavelength. We also explored the far-field beam patterns emitted by H-plane horn antennas attached to the waveguides. In the process we learned that the method of measuring the beam patterns has a significant impact on what is actually measured, and this may have an effect on most of the beam patterns of THz that have been reported to date. The beam pattern measurements improved significantly throughout the project, but more refinements of the measurement are required before a definitive determination of the beam-pattern can be made.

EXPERIMENTAL STUDIES ON THE KINETIC BEHAVIOR OF WATER BOILER TYPE REACTORS  

SciTech Connect

The KEWB Program is devoted to the study of the dynamic behavior of homogeneous type research reactors. The objectives of this program include studies to develop better and more complete understanding of phenomena which contribute to the kinetic behavior and the inherent safety of the water boiler reactor. The approach to the objectives has heen to construct a prototype 50 kw homogeneous reactor with the necessary auxiliary apparatus and to study the transient behavior of the system as a function of the more significant parameters which affect this behavior. These include the amount of reactivity release, rate of reactivity release, initial core pressure, initial core temperature, initial reactor power, and void volume above the core. Data are plotted.

Dusky dolphins of Kaikoura, New Zealand: behavioral effects of genetic sampling and analysis of population structure  

E-Print Network (OSTI)

Seasonal differences in group size, behavior, icrographics. distribution, and coloration patterns of dusky dolphins (Lacenorhynchus obscures) in Kaikoura, New Zealand, have led researchers to question whether "winter'' and "summer'' groups are temporally and behaviorally segregated into genetically distinct populations. Exfoliated skin samples were collected in Kaikoura from July 1997 to May 1998 for genetic analysis of 40 "winter'' and 40 "summer'' individuals via skin swab. A 473 base pair section of the mitochondrion DNA control region was amplified and sequenced for the 80 samples. Nucleotide and haplotype diversity were 0.16 and 0.98, respectively. AMOVA and phylogenetie analyses indicate "winter'' and "summer'' groups are not subdivided with respect to maternal lineages. Lack of subdivision between seasonal populations is further supported by: (1) demographic patterns determined from mismatch distribution analysis suggest New Zealand dusky dolphins underwent a population expansion in the Pleistocene; (2) current levels of diversity suggest the long-term effective population size has been large', (3) preliminary analysis of photo-identification data indicate individuals are present in Kaikoura both winter and summer; (4) comparison of 80 samples from Kaikoura to eight beach-east samples from locations throughout New Zealand reveal shared haplotypes between regions. Behavioral responses to sampling were recorded for 315 contacts and 48 controls. The number of pro-and pest-contact joyriders and sample time were used as indicators of group-level response to sampling. The behavioral state of dolphins prior to sampling or time of day did not affect responses to sampling. Small groups were found to be more sensitive to sampling. Dolphin groups appeared to habituate to sampling activities after the first hour spent sampling. Responses to sampling were mild with 18% showing no response to contact. The most frequent response was to move right or left of the bow. Thirty-three percent of dolphins returned to the bow within 10.8 [] 0.73 seconds. There was no significant difference between proportion of responses between treatment and control groups, suggesting a proportion of responses to sampling can be explained by normal behavior in the presence of a vessel.

Mechanical Behavior Studies of Depleted Uranium in the Presence of Hydrides  

DOE Green Energy (OSTI)

This project addresses critical issues related to aging in the presence of hydrides (UH{sub 3}) in DU and the subsequent effect on mechanical behavior. Rolled DU specimens with three different hydrogen concentrations and the as-rolled condition were studied. The texture measurements indicate that the hydrogen charging is affecting the initial as-rolled DU microstructure/texture. The macroscopic mechanical behavior suggests the existence of a threshold between the 0 wpmm H and 0.3 wppm H conditions. A VPSC simulation of the macroscopic strain-stress behavior, when taking into account only a texture effect, shows no agreement with the experiment. This suggests that the macroscopic mechanical behavior observed is indeed due to the presence of hydrogen/hydrides in the DU bulk. From the lattice strain variation it can be concluded that the hydrogen is affecting the magnitude and/or the nature of CRSS. The metallography indicates the specimens that underwent the hydrogen charging process, developed large grains and twinning, which were enhanced by the presence of hydrogen. Further studies using electron microscopy and modeling will be conducted to learn about the deformation mechanisms responsible for the observed behavior.

Polarization Behavior of Water in Extreme Aqueous Environments: A molecular dynamics study based on the Gaussian Charge Polarizable Water Model.  

Science Conference Proceedings (OSTI)

We study the polarization behavior of water under geologically-relevant extreme aqueous environments along four equidistant supercritical isotherms, 773 ! T (K) ! 1373, and over a wide pressure range, 0 order parameters and the magnitude of the average induced dipole moment of water. The predicted behavior indicates an isothermal linear dependence (a) between the magnitude of the average induced dipole moment ind and the average system density ! , (b) between the magnitude of the average induced dipole ind and that of the total dipole tot , resulting from (c) a compensating (inverse) dependence between the permanent-to-induced dipolar angle ! and the magnitude of the average induced dipole moment ind . Moreover, we interpret this behavior in terms of the evolution of the state dependent tetrahedral order parameter qT and the corresponding bond-order parameter Q6 , supplemented by the microstructural analysis based on the three site-site radial distribution functions of water and the distance-ranked nearest-neighbors distributions. Finally, we show that while water exhibits a dramatic microstructural transformation from an open four-coordinated hydrogen-bonded network at normal conditions to a quasi close-packed coordination, it still preserves a significant degree of hydrogen bonding.

A REVIEW OF ASSUMPTIONS AND ANALYSIS IN EPRI EA-3409,"HOUSEHOLD APPLIANCE CHOICE: REVISION OF REEPS BEHAVIORAL MODELS"  

SciTech Connect

This paper revises and extends EPRI report EA-3409, ''Household Appliance Choice: Revision of REEPS Behavioral Models.'' That paper reported the results of an econometric study of major appliance choice in new residential construction. Errors appeared in two tables of that report. We offer revised versions of those tables, and a brief analysis of the consequences and significance of the errors. The present paper also proposes several possible extensions and re-specifications of the models examined by EPRI. Some of these are judged to be highly successful; they both satisfy economic intuition more completely than the original specification and produce a better quality fit to the dependent variable. We feel that inclusion of these modifications produces a more useful set of coefficients for economic modeling than the original specification. This paper focuses on EPRI's models of residential space heating technology choice. That choice was modeled as a nested logit structure, with consumers choosing whether to have central air conditioning or not, and, given that choice, what kind of space heating system to have. The model included five space heating alternatives with central cooling (gas, oil, and electric forced-air; heat pumps; and electric baseboard) and eight alternatives without it (gas, oil, and electric forced-air; gas and oil boilers and non-central systems; and electric baseboard heat). The structure of the nested logit model is shown in Figure 1.

Phase Behavior, Solid Organic Precipitation, and Mobility Characterization Studies in Support of Enhanced Heavy Oil Recovery on the Alaska North Slope  

Science Conference Proceedings (OSTI)

The medium-heavy oil (viscous oil) resources in the Alaska North Slope are estimated at 20 to 25 billion barrels. These oils are viscous, flow sluggishly in the formations, and are difficult to recover. Recovery of this viscous oil requires carefully designed enhanced oil recovery processes. Success of these recovery processes is critically dependent on accurate knowledge of the phase behavior and fluid properties, especially viscosity, of these oils under variety of pressure and temperature conditions. This project focused on predicting phase behavior and viscosity of viscous oils using equations of state and semi-empirical correlations. An experimental study was conducted to quantify the phase behavior and physical properties of viscous oils from the Alaska North Slope oil field. The oil samples were compositionally characterized by the simulated distillation technique. Constant composition expansion and differential liberation tests were conducted on viscous oil samples. Experiment results for phase behavior and reservoir fluid properties were used to tune the Peng-Robinson equation of state and predict the phase behavior accurately. A comprehensive literature search was carried out to compile available compositional viscosity models and their modifications, for application to heavy or viscous oils. With the help of meticulously amassed new medium-heavy oil viscosity data from experiments, a comparative study was conducted to evaluate the potential of various models. The widely used corresponding state viscosity model predictions deteriorate when applied to heavy oil systems. Hence, a semi-empirical approach (the Lindeloff model) was adopted for modeling the viscosity behavior. Based on the analysis, appropriate adjustments have been suggested: the major one is the division of the pressure-viscosity profile into three distinct regions. New modifications have improved the overall fit, including the saturated viscosities at low pressures. However, with the limited amount of geographically diverse data, it is not possible to develop a comprehensive predictive model. Based on the comprehensive phase behavior analysis of Alaska North Slope crude oil, a reservoir simulation study was carried out to evaluate the performance of a gas injection enhanced oil recovery technique for the West Sak reservoir. It was found that a definite increase in viscous oil production can be obtained by selecting the proper injectant gas and by optimizing reservoir operating parameters. A comparative analysis is provided, which helps in the decision-making process.

Comparative study of eight equations of state for predicting hydrocarbon volumetric phase behavior  

Science Conference Proceedings (OSTI)

The objective of this study is to present a review of eight equations of state (EOS's) and compare their ability to predict the volumetric and phase equilibria of gas-condensate systems. Included in the study are the Peng-Robinson (PR), the Soave-Redlich-Kwong (SRK), the Schmidt-Wenzel (SW), the Usdin-McAuliffe (UM), the Heyen, the Kubic, the Adachi-Lu (AL), and the Patel-Teja (PT) EOS's. The SW equation exhibits a superior predictive capability for volumetric properties of condensate systems. The PR equation is found to represent the phase equilibrium behavior of condensate systems accurately. In terms of compressibility factors, the SW and PT equations give better predictions than other equations.

HPC Usage Behavior Analysis and Performance Estimation with Machine Learning Techniques  

Science Conference Proceedings (OSTI)

Most researchers with little high performance computing (HPC) experience have difficulties productively using the supercomputing resources. To address this issue, we investigated usage behaviors of the world s fastest academic Kraken supercomputer, and built a knowledge-based recommendation system to improve user productivity. Six clustering techniques, along with three cluster validation measures, were implemented to investigate the underlying patterns of usage behaviors. Besides manually defining a category for very large job submissions, six behavior categories were identified, which cleanly separated the data intensive jobs and computational intensive jobs. Then, job statistics of each behavior category were used to develop a knowledge-based recommendation system that can provide users with instructions about choosing appropriate software packages, setting job parameter values, and estimating job queuing time and runtime. Experiments were conducted to evaluate the performance of the proposed recommendation system, which included 127 job submissions by users from different research fields. Great feedback indicated the usefulness of the provided information. The average runtime estimation accuracy of 64.2%, with 28.9% job termination rate, was achieved in the experiments, which almost doubled the average accuracy in the Kraken dataset.

Statistical Analysis of the Fourth Case Study in Reverse Auction Research  

E-Print Network (OSTI)

Participating in an auction and winning items by placing bids has been in practice since at least 500 B.C. Auctions have evolved since then and anyone can now participate in one online and buy items ranging from clothes, electronics, automobiles and homes using online auction websites, such as eBay. A Reverse Auction varies from the traditional style of Auction where items or services are won by placing successive higher bids until the auction ends. The study of Reverse Auction was first introduced to Texas A & M University in 2004 and continues today, using a SQL based web system. This current research provides a detailed statistical analysis of the fourth case study in this long running work. This fourth case study involved the participation of five bidders who had no prior experience in Reverse Auctions. A Microsoft Access database system and ASP web based user interface was developed and used to conduct these initial studies. However, due to the limited capability of the Access system to handle more than a limited number of connections or bidders, a Microsoft SQL database and web system was developed in 2006 and has been used in all subsequent studies. Case studies have involved up to ten participants. The results from the fourth case study show that a Reverse Auction can result in an increase in the average cost of the job to the owner. Also, there is evidence of game play amongst the bidders and against the purchaser that causes their profits to rise as they gain proficiency in the game. This behavior has been termed as 'tacit collision', but it is considered a byproduct of the system and not illegal behavior. This study analyzes the fourth study data to investigate if the behavior termed "tacit collusion" is evident in the bidding data. This analysis is completed by performing a detailed statistical analysis of the bidding data. Analysis of the profit percentages illustrates the different stages of the game play amongst the bidders. This game play behavior is illustrated by plotting average number of bids to the profit made by each bidder. The data clearly suggests that the players became efficient in their bidding strategy, although some bidders are more efficient than others. This observation negates the common conception that Reverse Auctions will result in lowering average costs for the owners. The individual data of bidders for bids and profit reveal why some players were able to obtain higher than average results and why the others were not. This study can be taken further by analyzing the patterns of the successful and unsuccessful players to determine what causes them to gain or lose profits.

Analysis of the burping behavior of the cold solid methane moderator at IPNS (Intense Pulsed Neutron Source)  

SciTech Connect

Examination of the cold solid methane moderator at IPNS (Model II) revealed that a circumferential weld failed due to high internal pressure, such as would be caused by thermal expansion of solid methane or the release of Hydrogen gas upon spontaneous heating. This weld is the main object of current attention for a design of a replacement. The present paper deals with the processes which lead to the burping behavior and outlines the analysis of some of the consequences. The purpose is to determine conditions under which the system can operate at the lowest possible temperature, avoiding the problems experienced to data.

Stakeholder behavior and legislative influence: A case study of recreational water rights in Colorado  

E-Print Network (OSTI)

Colorado water law is based on 150 years of legal, constitutional, and administrative precedent. Much of this precedent encourages traditional consumptive uses of water and impedes non-consumptive uses. Throughout Colorado’s history, the water law system has evolved to include new codified uses of water. This paper analyzes the behavior of stakeholder groups that drove legislative changes in the Colorado General Assembly in the most recent example of this evolution—the inclusion of non-consumptive recreational in-channel water rights as a codified use of water. Using a qualitative case study research method, this study finds that collaboration among formerly disenfranchised stakeholders explains their legislative success despite the lesser degree of influence these groups have over water rights in Colorado. © 2008 Western Social Science Association.

Groups of policy actors influence the policy process significantly and can take the form of interrelated actors in policy communities (Kingdon, 2003), or coalitions of stakeholders within and outside government (Sabatier & Jenkins-Smith, 1993). These groups use internal coordinated action to promote their preferred versions of policy change. This paper analyzes the role that groups played in the process of policy change in the case of recreational water

An analysis of radionuclide behavior in water pools during accidents at the Annular Core Research Reactor  

SciTech Connect

Physical and chemical phenomena that will affect the behavior of radionuclides released from fuel in the Annular Core Research Reactor during a hypothetical, core disruptive accident are described. The phenomena include boiling of water on heated clad, metal-water reactions, vapor nucleation to form aerosol particles, coagulation of aerosol particles, aerosol deposition within bubbles rising through the shield pool, vapor dissolution in the shield pool, and revaporization of radionuclides from the shield pool. A model of these phenomena is developed and applied to predict the release of radionuclides to the confinement building of the Annular Core Research Reactor. It is found that the shield pool provides overall decontamination factors for particulate of about 2.8 {times} 10{sup 5} and decontamination factors for noble gases of about 2.5--3.7. These results are found to be sensitive to the predicted clad temperature and bubble behavior in the shield pool. Slow revalorization of krypton, xenon and iodine from the shield pool is shown to create a prolonged, low-intensity source term of radioactive material to the confinement atmosphere.

Fluid bed adsorption of carbon dioxide on immobilized polyethyenimine (PEI): kinetic analysis and breakthrough behavior  

Science Conference Proceedings (OSTI)

The adsorption of carbon dioxide (CO{sub 2}) by immobilized polyethylenimine (PEI) on mesoporous silica was investigated in a fluid bed. The tests were performed to determine breakthrough behavior with varying bed temperature, flow rates and feed concentrations. Experimental breakthrough curves were analyzed using a theoretical 1D model developed by Bohart and Adams. The results showed that Bohart-Adams model was suitable for the normal description of breakthrough curve for the temperature ranges of 40-90{degree}C. The maximum capacity increased with temperature up to 70{degree}C and then decreased. The adsorption rate constant exhibited a negative temperature dependence decreasing as the temperature increased. Parameters characteristic of a fluid bed adsorber were inferred from these breakthrough curves including the breakthrough time, saturation time, critical reactor length, and length of mass transfer zone LMTZ. These parameters can be used to design fluid bed adsorption system without resolving the mechanistic contributions of dispersion, mixing, and intraparticle diffusion.

Stage 1 behavior in a stress corrosion study of Type 304 stainless steel  

SciTech Connect

In stress corrosion studies, crack velocity plotted with respect to stress intensity generally yields a characteristic curve with three distinct regions. Stage I exhibits a threshold (K{sub ISCC}) followed by a rapid increase in crack velocity (da/dt) for small changes in stress intensity. Stage II is characterized by an essentially constant crack velocity with increases in the stress intensity. Stage III exhibits a rapid increase in crack velocity for small increases in stress intensity leading to fracture. Stage I behavior has been poorly characterized in literature due to previous emphasis on determining the threshold K{sub ISCC} and difficulty and uncertainty in measuring of a large increase in crack velocity with only incremental changes in stress intensity. Tests were conducted in the stage I regime to measure crack velocity as a function of constant stress intensity. Constant K specimens were prepared according to the Mostovoy design, (a tapered double cantilever beam). Specimens were prepared from Type 304 stainless steel containing 0.06 wt% C solution annealed at 1100C for 1 hour, water quenched, and annealed at 625C for 24 hours to produce sensitization. A sodium thiosulfate solution at 50{degree}C was chosen as the test environment.

Analysis of the high energy behavior of the forward scattering parameters -- {sigma}{sub tot}, {rho}, and B  

SciTech Connect

Recent experimental results, namely, the remeasurement of the {rho} value by UA4/2 at {radical}s = 546 GeV, together with a new analysis by the E710 group of {sigma}{sub tot}, {rho} and B at {radical}s = 1800 GeV, as well as their measurement of {sigma}{sub tot} and B at {radical}s = 1020 GeV, have provided important anchor points for the high energy behavior of {anti p}p scattering. The authors analyze high energy {anti p}p and pp data, using two distinct (and dissimilar) analysis techniques: (1) asymptotic amplitude analysis, under the assumption that they have reached {open_quotes}asymptopia{close_quotes}, and (2) an eikonal model whose amplitudes are designed to mimic real QCD amplitudes. The former gives strong evidence for a log (s/s{sub 0}) dependence at current energies and not log{sup 2}(s/s{sub 0}), and demonstrates that odderons are not necessary to explain the experimental data. The latter gives a unitary model for extrapolation into true {open_quote}asymptopia{close_quote} from current energies, allowing them to predict the values of the total cross section at future supercolliders. Using their QCD-model, the authors obtain {sigma}{sub tot}(16 TeV)= 106 {+-} 4 mb and {sigma}{sub tot}(40 TeV) = 120 {+-} 5 mb.

CFD Analysis for Flow Behavior Characteristics in the Upper Plenum during low flow/low pressure transients for the Gas Cooled Fast Reactor (GCFR)  

Science Conference Proceedings (OSTI)

Gas coolant at low pressure exhibits poor heat transfer characteristics. This is an area of concern for the passive response targeted by the Generation IV GCFR design. For the first 24 hour period, the decay heat removal for the GCFR design is dependent on an actively powered blower, which also would reduce the temperature in the fuel during transients, before depending on the passive operation. Natural circulation cooling initiates when the blower is stopped for the final phase of the decay heat removal, as under forced convection the core decay heat is adequately cooled by the running blower. The ability of the coolant to flow in the reverse direction or having recirculation, when the blowers are off, necessitates more understanding of the flow behavior characteristics in the upper plenum. The work done here focuses primarily on the period after the blower has been turned off, as the core is adequately cooled when the blowers are running, thus there was no need to carry out the analysis for the first 24 hours. In order to understand the plume behavior for the GCFR upper plenum several cases were run, with air, helium and helium-air mixture. For each case, the FLUENT was used to characterize the steady state velocity vectors and corresponding temperature in the upper plenum under passive decay heat removal conditions. This study will provide better insight into the plume interaction in the upper plenum at low flow and low pressure conditions.

Microfluidic Platforms for on-chip Formulation and Small-Angle x-ray Analysis of the Phase Behavior of Lipid/Water Mixtures  

SciTech Connect

We present a microfluidic platform for on-chip formulation and X-ray analysis of lipidic mesophases formed upon mixing lipids and water. The platform is designed to study the effect of detergents on the phase behavior of lipid/water mixtures. The platform allows automated preparation of multiple samples of different composition from stock solutions and subsequent on-chip small-angle X-ray diffraction (SAXS) data collection. To ensure X-ray transparency of the platform we used thin layers of cyclic olefin copolymer (COC) and PDMS. The viability of the platform is demonstrated by mapping out a section of the phase diagram for lipid monoolein mixed with solutions of detergent {beta}-octylglucoside. The platform reported here is a viable alternative to the traditional method of establishing phase diagrams for lipid/solution mixtures. Compared to the conventional approach, a significantly smaller amount of sample is required for mapping phase diagrams of lipidic mesophases and samples of various compositions are prepared automatically. In ongoing work we are using these chips to rapidly determine the phase behavior of a range of lipids to establish their suitability for membrane protein crystallization, especially with respect to their sensitivity to detergent concentration.

A Study of Transient Behavior During Start-Up of Residential Heat Pumps  

E-Print Network (OSTI)

An experimental and analytical study concerned with the transient performance of heat pumps is presented. A series of tests were performed to study and characterize the transient sensible and dehumidification performance of a heat pump in the cooling node. All the tests were conducted according to the ASHRAE Standard (1983). The effects of indoor dry-bulb temperature (72 to 80 F), indoor relative humidity (20 to 67%), outdoor dry-bulb temperature (82 to 100 F), cycling rate (0.8 to 10 cph) and percent ON-time (20 to 95%) on the transient performance (sensible and latent capacity, efficiency and sensible heat ratio) are addressed in this study. The results indicated that part load factor (PLF) can be as low as 0.65 at low percent ON-times and high cycling rates. The combination of low percent ON-times and high cycling rates produced maximum cyclic losses. The dehumidification process usually started between 60 to 150 seconds after start-up depending on the indoor ambient conditions, percent ON-time and cycling rate. The sensible and latent capacity response and part load efficiency of the heat pump increased with an increase in indoor relative humidity. There was a slight increase in PLF with indoor dry-bulb temperature. The outdoor dry-bulb temperature did not have any effect on the transient performance. Based on the functional relationship of PLF and coefficient of degradation (C_D) with the five independent variables a multiple linear regression analysis was performed on the experimental data. The analysis yielded two general equations to predict PLF and C_D. A lumped parameter heat pump transient analysis computer model was developed, which drew upon methodologies from the earlier models by Chi and Didion [1982] and Oak Ridge National Laboratory [1981]. The model was capable of simulating the transient response of a vapor compression air-to-air heat pump commonly used in residential applications. The simulated results were in good agreement with the laboratory results at high percent ON-times (> 20) and high relative humidities (> 45).

Dynamic behavior and control requirements of an atmospheric fluidized-bed coal combustion power plant: A conceptual study  

Science Conference Proceedings (OSTI)

A first-principles model of a nominal 20-MW atmospheric-pressure fluidized-bed coal combustion (AFBC) power plant was developed to provide insight into fundamental dynamic behavior of fluidized-bed systems. The control system included major loops for firing rate, steam pressure and temperature, forced and induced draft air flow, SO/sub 2/ emission, drum water level, evaporator recirculation, and bed level. The model was used to investigate system sensitivity to design features such as the distribution of heat transfer surface among the bed boiler and superheater and the out-of-bed superheater. Also calculated were the sensitivities of temperatures, pressures, and flow rates to changes in throttle, attemperator, and feedwater valve settings and forced and induced draft damper settings. The large bed mass, accounting for approx.40% of the active heat capacity, may vary under load change and could impact controller tuning. Model analysis indicated, however, that for the design studied, the change in bed mass does not appear to significantly affect controller tuning even if the bed mass varies appreciably under load-following conditions. Several bed designs are being considered for AFBC plants, some with partitions between bed sections and some without, and these differences may significantly affect the load-following capability of the plant. The results indicated that the slumping mode of operation can cause distortion of the heat source/sink distribution in the bed such that the load-following capability (rate of load change) of the plant may be reduced by as much as a factor of 5 compared with the mode in which tube surface is exposed. 9 refs., 13 figs., 6 tabs.

A grateful dead analysis: the relationship between concert and listening behavior  

Science Conference Proceedings (OSTI)

The Grateful Dead was an American band born out of the 1960s San Francisco, California psychedelic movement, that played music together from 1965 to 1995. Despite relatively little popular radio airtime, while on tour the Grateful Dead enjoyed a cult-like following from a fan base that numbered in the millions. Still today, some ten years after dissolution, the band remains popular according to online music services, such as last.fm. This article presents a comparative analysis between 1,590 of the Grateful Dead's live concert set lists from 1972 to 1995 and 2,616,990 Grateful Dead listening events by last.fm users from August 2005 to October 2007. While there is a strong correlation between how songs were played in concert and how they were listened to by last.fm members, the outlying songs in this trend identify interesting aspects of the band and their present-day fans.

Geothermal field case studies that document the usefulness of models in predicting reservoir and well behavior  

SciTech Connect

The geothermal industry has shown significant interest in case histories that document field production histories and demonstrate the techniques which work best in the characterization and evaluation of geothermal systems. In response to this interest, LBL has devoted a significant art of its geothermal program to the compilation and analysis of data from US and foreign fields (e.g., East Mesa, The Geysers, Susanville, and Long Valley in California; Klamath Falls in Oregon; Valles Caldera, New Mexico; Cerro Prieto and Los Azufres in Mexico; Krafla and Nesjavellir in Iceland; Larderello in Italy; Olkaria in Kenya). In each of these case studies we have been able to test and validate in the field, or against field data, the methodology and instrumentation developed under the Reservoir Technology Task of the DOE Geothermal Program, and to add to the understanding of the characteristics and processes occurring in geothermal reservoirs. Case study results of the producing Cerro Prieto and Olkaria geothermal fields are discussed in this paper. These examples were chosen because they illustrate the value of conceptual and numerical models to predict changes in reservoir conditions, reservoir processes, and well performance that accompany field exploitation, as well as to reduce the costs associated with the development and exploitation of geothermal resources. 14 refs., 6 figs.

Predicting the devolatilization behavior of any coal from its ultimate analysis  

Science Conference Proceedings (OSTI)

FLASHCHAIN has been developed to predict yields and product characteristics from any coal for any operating conditions. This evaluation demonstrates the model`s utility for the usual situation where the ultimate analysis is the only sample-specific information available. It also identifies the key reaction centers in coal as its structural components called labile bridges. Their elemental compositions are grossly different than the analogous whole-coal properties, showing much stronger rank dependences and a much higher degree of sample-to-sample variability. In light of these findings, it is inconceivable that bride conversion rates are rank-independent. Parameters in the rate law for bridge conversion in FLASHCHAIN are now explicitly related to the elemental compositions of bridges. The (O/C){sub B} ratios are the best regression variable for the rate constants because oxygen is the most effective promoter of pyrolytic decompositions. The (O/H){sub B} rates are best for the selectivity coefficient between scission and condensation into char links because oxygen promotes crosslinking but hydrogen addition to broken bridge fragments stabilizes them. These extensions are evaluated in comparisons against a database of 27 coals that span all ranks from lignite to anthracite, for heating rates from 5 to 5,000 K/s, ultimate temperatures to 1,300 K, and pressures from vacuum to 70 MPa. In four out of five cases, predicted total and tar yields are within experimental uncertainties. The model is also used to rigorously define nominal devolatilization rates for diverse coal types and broad ranges of operating conditions. Nominal rates have very low activation energies, proving that heat and mass transport resistances are not responsible for the low values because this theory is completely free of these considerations. Whereas nominal rates are rather insensitive to coal type variations and independent of pressure, they vary in proportion to changes in heating rate.

Analysis and Synthesis of Load Forecasting Data for Renewable Integration Studies: Preprint  

SciTech Connect

As renewable energy constitutes greater portions of the generation fleet, the importance of modeling uncertainty as part of integration studies also increases. In pursuit of optimal system operations, it is important to capture not only the definitive behavior of power plants, but also the risks associated with systemwide interactions. This research examines the dependence of load forecast errors on external predictor variables such as temperature, day type, and time of day. The analysis was utilized to create statistically relevant instances of sequential load forecasts with only a time series of historic, measured load available. The creation of such load forecasts relies on Bayesian techniques for informing and updating the model, thus providing a basis for networked and adaptive load forecast models in future operational applications.

Additional EIPC Study Analysis: Interim Report on High Priority Topics  

SciTech Connect

Between 2010 and 2012 the Eastern Interconnection Planning Collaborative (EIPC) conducted a major long-term resource and transmission study of the Eastern Interconnection (EI). With guidance from a Stakeholder Steering Committee (SSC) that included representatives from the Eastern Interconnection States Planning Council (EISPC) among others, the project was conducted in two phases. Phase 1 involved a long-term capacity expansion analysis that involved creation of eight major futures plus 72 sensitivities. Three scenarios were selected for more extensive transmission- focused evaluation in Phase 2. Five power flow analyses, nine production cost model runs (including six sensitivities), and three capital cost estimations were developed during this second phase. The results from Phase 1 and 2 provided a wealth of data that could be examined further to address energy-related questions. A list of 13 topics was developed for further analysis; this paper discusses the first five.

Phase behavior and miscible process analysis of Cusiana Field hydrocarbon system using a reduced component equation of state  

E-Print Network (OSTI)

Cusiana Field is located in the foothill belt of Llanos basin in eastern Colombia. This field has large reserves of light hydrocarbons in Mirador (Tertiary), Barco and Guadalupe (Cretaceous) formations. The development of this field beginning with Mirador formation is underway, and includes a gas cycling project. A complex hydrocarbon system has been found in the reservoirs. Because of vertical compositional variation, fluids grade from retrograde gas to black oil as they pass through critical conditions. Phase behavior of these fluids has an important effect on the in-place volume determination and on field development strategies. Previous reservoir analysis and predictions have been done using a 10-component equation of state (EOS), characterized with the help of an extensive laboratory measurement program, including PVT depletion experiments, separation-type tests, and gas injection tests. We developed a reduced component equation of state to reduce time and resources required for full-field compositional simulations using the 10-component EOS. Three different lumping schemes were tried, two of them with six components and one with seven. A validation process was carried out to check the consistency of this reduced component EOS. This process consisted of two steps: The first step was the match of a large set of "experimental" type data generated with the 10-component EOS. The second step was the matching of the saturation and compositional path followed by reservoir oil during a simulated gas injection displacement process. A coreflood experiment and a two-dimensional cross-section of the reservoir were simulated with a one-dimensional and a two-dimensional model, respectively. These models, previously developed by British Petroleum, matched laboratory and field data using the 10-component EOS. Here, we replaced the 10-component EOS with our reduced component EOS and compared the results. All three reduced EOS successfully went through the first step of validation, matching the "experimental" PVT data, but only the seven-component EOS got a good match of the oil saturation and compositional path in the second step. This seven-component EOS reduced the simulation time to about 68% for the one-dimensional case and to 60% for the two-dimensional case. Although multicontact miscibility is not reached during the gas displacement process, vaporization of oil by injected lean gas proved to be an efficient oil recovery mechanism.

A Nuclear Reaction Analysis study of fluorine uptake in flint  

SciTech Connect

Nuclear Reaction Analysis (NRA) using the {sup 19}F(p,{alpha}{gamma}){sup 16}O resonance reaction is a powerful method of fluorine depth profiling. We have used this method to study the fluorine uptake phenomenon in mineral flint, which could potentially develop into a method of dating archeological flint artifacts. Flint samples cut with a rock saw were immersed in aqueous fluoride solutions for different times for the uptake study. The results suggest that fluorine uptake is not a simple phenomenon, but rather a combination of several simultaneous processes. Fluorine surface adsorption appears to play an important role in developing the fluorine profiles. The surface adsorption was affected by several parameters such as pH value and fluorine concentration in the solution, among others. The problem of surface charging for the insulator materials during ion bombardment is also reported.

Fundamental study on transient bubble (slug) behavior by characterizing transient forces of solid particles in fluidized beds. 1990 Annual report  

SciTech Connect

The objective of this work is to recognize and interpret the signals of transient motion of bubbles (slugs) in fluidized beds by measuring and utilizing the signals of transient motion of solid particles. The two signals were measured simultaneously and also synchronized by using the TTL signal technique in the same fluidized beds. Also, a simultaneous study of video bubble image, transient force and pressure signals was initiated in a two dimensional fluidized bed. we successfully synchronized three signals so that the relationship of bubble behavior and force pressure signals can be identified and characterized. It has been found that bubble image can well be correlated to the transient force signal of solid particles under certain conditions in three dimensional fluidized beds. Accordingly, it seems that the transient force signals can significantly help understanding the transient motion of bubbles (slugs), which is important to design the fluidized beds.

Proliferation concerns in the Russian closed nuclear weapons complex cities : a study of regional migration behavior.  

SciTech Connect

The collapse of the Soviet Union in 1991 left the legacy of the USSR weapons complex with an estimated 50 nuclear, chemical, and biological weapons cities containing facilities responsible for research, production, maintenance, and destruction of the weapons stockpile. The Russian Federation acquired ten such previously secret, closed nuclear weapons complex cities. Unfortunately, a lack of government funding to support these facilities resulted in non-payment of salaries to employees and even plant closures, which led to an international fear of weapons material and knowledge proliferation. This dissertation analyzes migration in 33 regions of the Russian Federation, six of which contain the ten closed nuclear weapons complex cities. This study finds that the presence of a closed nuclear city does not significantly influence migration. However, the factors that do influence migration are statistically different in regions containing closed nuclear cities compared to regions without closed nuclear cities. Further, these results show that the net rate of migration has changed across the years since the break up of the Soviet Union, and that the push and pull factors for migration have changed across time. Specifically, personal and residential factors had a significant impact on migration immediately following the collapse of the Soviet Union, but economic infrastructure and societal factors became significant in later years. Two significant policy conclusions are derived from this research. First, higher levels of income are found to increase outmigration from regions, implying that programs designed to prevent migration by increasing incomes for closed city residents may be counter-productive. Second, this study finds that programs designed to increase capital and build infrastructure in the new Russian Federation will be more effective for employing scientists and engineers from the weapons complex, and consequently reduce the potential for emigration of potential proliferants.

SILICA GEL BEHAVIOR UNDER DIFFERENT EGS CHEMICAL AND THERMAL CONDITIONS: AN EXPERIMENTAL STUDY  

Science Conference Proceedings (OSTI)

Fractures and fracture networks are the principal pathways for migration of water and contaminants in groundwater systems, fluids in enhanced geothermal systems (EGS), oil and gas in petroleum reservoirs, carbon dioxide leakage from geological carbon sequestration, and radioactive and toxic industrial wastes from underground storage repositories. When dealing with EGS fracture networks, there are several major issues to consider, e.g., the minimization of hydraulic short circuits and losses of injected geothermal fluid to the surrounding formation, which in turn maximize heat extraction and economic production. Gel deployments to direct and control fluid flow have been extensively and successfully used in the oil industry for enhanced oil recovery. However, to the best of our knowledge, gels have not been applied to EGS to enhance heat extraction. In-situ gelling systems can either be organic or inorganic. Organic polymer gels are generally not thermostable to the typical temperatures of EGS systems. Inorganic gels, such as colloidal silica gels, however, may be ideal blocking agents for EGS systems if suitable gelation times can be achieved. In the current study, we explore colloidal silica gelation times and rheology as a function of SiO{sub 2} concentration, pH, salt concentration, and temperature, with preliminary results in the two-phase field above 100 C. Results at 25 C show that it may be possible to choose formulations that will gel in a reasonable and predictable amount of time at the temperatures of EGS systems.

Tissue Engineering Approaches for Studying the Effect of Biochemical and Physiological Stimuli on Cell Behavior  

E-Print Network (OSTI)

Tissue engineering (TE) approaches have emerged as an alternative to traditional tissue and organ replacements. The aim of this work was to contribute to the understanding of the effects of cell-material and endothelial cell (EC) paracrine signaling on cell responses using poly(ethylene glycol) diacrylate (PEGDA) hydrogels as a material platform. Three TE applications were explored. First, the effect of glycosaminoglycan (GAG) identity was evaluated for vocal fold restoration. Second, the influence of GAG identity was explored and a novel approach for stable endothelialization was developed for vascular graft applications. Finally, EC paracrine signaling in the presence of cyclic stretch, and hydrophobicity and inorganic content were studied for osteogenic applications. In terms of vocal fold restoration, it was found that vocal fold fibroblast (VFF) phenotype and extracellular matrix (ECM) production were impacted by GAG identity. VFF phenotype was preserved in long-term cultured hydrogels containing high molecular weight hyaluronan (HAHMW). Furthermore, collagen I deposition, fibronectin production and smooth muscle alpha-actin (SM-alpha-actin) expression in PEG-HA, PEG-chondroitin sulfate C and PEG- heparan sulfate (HS) gels suggest that CSC and HS may be undesirable for vocal fold implants. Regarding vascular graft applications, the impact of GAG identity on smooth muscle cell (SMC) foam cell formation was explored. Results support the increasing body of literature that suggests a critical role for dermatan sulfate (DS)-bearing proteoglycans in early atherosclerosis. In addition, an approach for fabricating bi-layered tissue engineering vascular grafts (TEVGs) with stable endothelialization was validated using PEGDA as an intercellular "cementing" agent between adjacent endothelial cells (ECs). Finally, mesenchymal stem cell (MSC) differentiation toward osteogenic like cells was evaluated. ECM and cell phenotypic data showed that elevated scaffold inorganic content and hydrophobicity were indeed correlated with increased osteogenic differentiation. Moreover, the present results suggest that EC paracrine signaling enhances MSC osteogenesis in the presence of cyclic stretch.

Study on severe accident fuel dispersion behavior in the Advanced Neutron Source reactor at Oak Ridge National Laboratory  

SciTech Connect

Core flow blockage events are a leading contributor to core damage initiation risk in the Advanced Neutron Source (ANS) reactor. During such an accident, insufficient cooling of the fuel could result in core heatup and melting under full coolant flow condition. Coolant inertia forces acting on the melt surface would likely break up the melt into small particles. Under thermal-hydraulic conditions of ANS coolant channel, micro-fine melt particles are expected. Heat transfer between melt particle and coolant, which affects particle breakup, was studied. The study indicates that the thermal effect on melt fragmentation seems to be negligible because the time corresponding to the breakup due to hydrodynamic forces is much shorter than the time for the melt surface to solidify. The study included modeling and analyses to predict transient behavior and transport of debris particles throughout the coolant system. The transient model accounts for the surface forces acting on the particle that results from the pressure variation on the surface, inertia, virtual mass, viscous force due to relative motion of particle in the coolant, gravitation, and resistance due to inhomogenous coolant velocity radially across piping due to possible turbulent coolant motions. Results indicate that debris particles would reside longest in heat exchangers because of lower coolant velocity there. Also core debris tends to move together upon melting and entrainment.

Core flow blockage events have been identified as a leading contributor to core damage initiation risk in the Advanced Neutron Source (ANS) reactor. During such an accident, insufficient cooling of the fuel in a few adjacent blocked coolant channels out of several hundred channels, could also result in core heatup and melting under full coolant flow condition in other coolant channels. Coolant inertia forces acting on the melt surface would likely break up the melt into small particles. Under thermal-hydraulic conditions of ANS coolant channel, micro-fine melt particles are expected. Heat transfer between melt particle and coolant, which affects the particle breakup characteristics, was studied. The study indicates that the thermal effect on melt fragmentation seems to be negligible because the time corresponding to the breakup due to hydrodynamic forces is much shorter than the time for the melt surface to solidify. The study included modeling and analyses to predict transient behavior and transport of debris particles throughout the coolant system.

Finite Element Analysis of Ballistic Penetration of Plain Weave Twaron CT709® Fabrics: A Parametric Study  

E-Print Network (OSTI)

The ballistic impact of Twaron CT709® plain weave fabrics is studied using an explicit finite element method. Many existing approximations pertaining to woven fabrics cannot adequately represent strain rate-dependent behavior exhibited by the Twaron fabrics. One-dimensional models based on linear viscoelasticity can account for rate dependency but are limited by the simplifying assumptions on the fabric architecture and stress state. In the current study, a three-dimensional fabric model is developed by treating each individual yarn as a continuum. The yarn behavior is phenomenologically described using a three-dimensional linear viscoelastic constitutive relation. A user subroutine VUMAT for ABAQUS/Explicit® is developed to incorporate the constitutive behavior. By using the newly developed viscoelasticity model, a parametric study is carried out to analyze the effects of various parameters on the impact behavior of the Twaron fabrics, which include projectile shape and mass, gripping conditions, inter-yarn friction, and the number of fabric layers. The study leads to the determination of the optimal number of fabric layers and the optimized level of inter-yarn friction that are needed to achieve the maximum energy absorption at specified impact speeds. The present study successfully utilizes the combination of 3D weave architecture and the strain rate dependent material behavior. Majority of the existing work is based either on geometry simplification or assumption of elastic material behavior. Another significant advantage with the present approach is that the mechanical constitutive relation, coded in FORTRAN®, is universal in application. The desired material behavior can be obtained by just varying the material constants in the code. This allows for the extension of this work to any fabric material which exhibits a strain-rate dependent behavior in addition to Twaron®. The results pertaining to optimal number of fabric layers and inter-yarn friction levels can aid in the manufacturing of fabric with regard to the desired level of lubrication/additives to improve the fabric performance under impact.

Fe-Co-Mo alloys show extraordinary mechanical properties which make them potential candidates for various high-performance applications. In the present study, for the first time, the precipitation behavior in a Fe-25 at.%Co-9 at.%Mo alloy was studied by small-angle X-ray scattering using high-energy synchrotron radiation. The specimens were isothermally aged in an in-situ furnace. The small-angle X-ray scattering patterns showed scaling behavior and were evaluated by employing a model function from the literature. This approach provides information about the characteristic length scale and the volume fraction of the precipitates in the alloy.

Uncertainty Studies of Real Anode Surface Area in Computational Analysis for Molten Salt Electrorefining  

SciTech Connect

This study examines how much cell potential changes with five differently assumed real anode surface area cases. Determining real anode surface area is a significant issue to be resolved for precisely modeling molten salt electrorefining. Based on a three-dimensional electrorefining model, calculated cell potentials compare with an experimental cell potential variation over 80 hours of operation of the Mark-IV electrorefiner with driver fuel from the Experimental Breeder Reactor II. We succeeded to achieve a good agreement with an overall trend of the experimental data with appropriate selection of a mode for real anode surface area, but there are still local inconsistencies between theoretical calculation and experimental observation. In addition, the results were validated and compared with two-dimensional results to identify possible uncertainty factors that had to be further considered in a computational electrorefining analysis. These uncertainty factors include material properties, heterogeneous material distribution, surface roughness, and current efficiency. Zirconium's abundance and complex behavior have more impact on uncertainty towards the latter period of electrorefining at given batch of fuel. The benchmark results found that anode materials would be dissolved from both axial and radial directions at least for low burn-up metallic fuels after active liquid sodium bonding was dissolved.

The Effect of Green Investment on Corporate Behavior', Journal of Finance and Quantitative Analysis 36(4  

E-Print Network (OSTI)

We thank Mary Kelly and Jim Yu for their research assistance and we are grateful for the useful comments of the participants of the PaciÞc Northwest Finance Conference, the JFQA referees, and the Editor of the This paper explores the effect of exclusionary ”ethical investing ” on corporate behavior in a risk averse, equilibrium setting. While arguments exist that ethical investing can inßuence a Þrm’s cost of capital, and so affect investment, no equilibrium model has been presented to do so. We show that exclusionary ethical investing leads to ”polluting ” Þrms being held by fewer investors since ”green ” investors eschew polluting Þrms ’ stock. This lack of risk-sharing among ”non-green” investors leads to lower stock prices for polluting Þrms, thus raising their cost of capital. If the higher cost of capital more than overcomes a cost of reforming (i.e., a polluting Þrm cleaning up its activities), then polluting Þrms will become socially responsible because of exclusionary ethical investing. A key determinant of the incentive of polluting Þrms to reform is the fraction of funds controlled by green investors. In our model, empirically reasonable parameter estimates indicate that more than 20 % green investors are required to induce any polluting Þrms to reform. Existing The concept of ethical investing has received considerable attention and has led to the formation of different forms of ethical mutual funds.

In-Situ TEM Study Of Lithiation Behavior Of Silicon Nanoparticles Attached To And Embedded In A Carbon Matrix  

Science Conference Proceedings (OSTI)

Rational design of silicon and carbon nanocomposite with a special topological feature has been demonstrated to be a feasible way for mitigating the capacity fading associated with the large volume change of silicon anode in lithium ion batteries. Although the lithiation behavior of silicon and carbon as individual component has been well understood, lithium ion transport behavior across a network of silicon and carbon are still lacking. In this paper, we probe the lithiation behavior of silicon nanoparticles attached to and embedded in a carbon nanofiber using in-situ TEM and continuum mechanical calculation. We found that aggregated silicon nanoparticles show contact flattering upon initial lithiation, which is characteristically analogous to the classic sintering of powder particles by neck-growth mechanism. As compared with the surface-attached silicon particle, particles embedded in the carbon matrix show delayed lithiation. Depending on the strength of the carbon matrix, lithiation of the embedded silicon nanoparticle can lead to the fracture of the carbon fiber. These observations provide insights on lithium ion transport in the network structured composite of silicon and carbon, and ultimately provide fundamental guidance for mitigating the failure of battery due to the large volume change of silicon anode.

The U.S. Department of Energy's (DOE) study of 20% Wind Energy by 2030 was conducted to consider the benefits, challenges, and costs associated with sourcing 20% of U.S. energy consumption from wind power by 2030. This study found that with proactive measures, no insurmountable barriers were identified to meet the 20% goal. Following this study, DOE and the National Renewable Energy Laboratory (NREL) conducted two more studies: the Eastern Wind Integration and Transmission Study (EWITS) covering the eastern portion of the U.S., and the Western Wind and Solar Integration Study (WWSIS) covering the western portion of the United States. The WWSIS was conducted by NREL and research partner General Electric (GE) in order to provide insight into the costs, technical or physical barriers, and operational impacts caused by the variability and uncertainty of wind, photovoltaic, and concentrated solar power when employed to serve up to 35% of the load energy in the WestConnect region (Arizona, Colorado, Nevada, New Mexico, and Wyoming). WestConnect is composed of several utility companies working collaboratively to assess stakeholder and market needs to and develop cost-effective improvements to the western wholesale electricity market. Participants include the Arizona Public Service, El Paso Electric Company, NV Energy, Public Service of New Mexico, Salt River Project, Tri-State Generation and Transmission Cooperative, Tucson Electric Power, Xcel Energy and the Western Area Power Administration.

However, since they were wild animals, we can extrapolate from their modern contemporaries and from our knowledge of their individual anatomies what kind of behaviors they exhibited.

Plutonium Mobility Studies: 216-Z-9 Trench Sample Analysis Results  

SciTech Connect

A variety of analyses were conducted on selected sediment samples collected from two wells (299 W15-46 and 299-W15-48) drilled near the 216-Z-9 Trench to elucidate the form and potential for Pu and Am to be mobilized under present conditions and those that could be expected in future remediation scenarios. Analyses included moisture content, determination of the less than sand size fraction (silt plus clay), carbon analysis, SEM/EDS analysis, microwave-assisted acid digestions for total element analysis, and extraction tests using Hanford groundwater as the leachate. Results of the extraction tests were used as input to conduct equilibrium geochemical modeling of the solutions with Geochemist’s Workbench®. Geochemical modeling results for Pu were evaluated in terms of recent conclusions regarding the solubility and redox reactions of Pu by Neck et al. (2007a, 2007b). It was found that the highest concentrations of Pu and Am were associated with sediments of low silt/clay content and occur above silt/clay rich layers within the sediment profile. It was also found that the Pu and Am were relatively enriched in the silt/clay portion of these samples. The fact that the highest concentrations of Pu and Am occurred in sediments with low silt/clay contents suggests that waste solutions had perched on top of the low permeability silt/clay rich layers and interactions with the high silt/clay layers was minimal. SEM/EDS analysis indicated that the Pu and Am in these sediments does not occur as discrete micron size particles, and therefore must occur as mononuclear or polynuclear/ nanoclusters size particles adsorbed throughout the sediment samples. Leaching of these samples with Hanford groundwater indicates that release of Pu and Am from the sediments is correlated most significantly with the acidity of the water and not the initial concentrations of Pu and Am in the sediments. Only extracts that were acidic after contact with the sediments (pH 4.3 to 5.4) contained detectable concentrations of extractable Pu and Am. Water extracts from samples containing high concentrations of TBP suggest that if the TBP degradation products DBP and MBP are available in these sediments, they do not significantly increase the extractability of Pu or Am. Geochemical modeling results suggest that the concentrations of Am in water in contact with these sediments is not controlled by the solubility of Am(OH)3(c), but rather by desorption of Am that has been previously adsorbed to the sediments during the period of active wastewater disposal. Sediment extracts that had measureable concentrations of Am only occurred in samples that were fairly acidic (pH 4.3 to 4.6), indicating that Am will remain effectively sequestered to sediments when pH conditions approach those of normal Hanford groundwater (mildly alkaline, ~ pH 8). The geochemical modeling results indicate that Pu in acidic extracts is significantly undersaturated with respect to PuO2(am). However, recent reviews of Pu solubility and redox reactions suggest that the data used for these calculations is incomplete (Neck et al. 2007a, 2007b). The results of Neck et al. (2007a, 2007b) suggest that Pu concentrations in solutions in contact with the 216-Z-9 Trench sediment samples might be controlled by a mixed valent solid phase [(PuV)2x(PuIV)1-2xO2+x(am)] with various dissolved Pu(V) complexes and Pu(IV)O2(am) colloids or nanoclusters being the dominant species in solution for typical Hanford groundwater conditions. Adsorption is likely to have a major impact on the mobility of these species (Neck et al. 2007a, 2007b; Clark et al. 2006; Kaplan et al. 2006; Powell et al. 2005). Further research is planned to verify these hypotheses.

Wind Turbine Gearbox Condition Monitoring Round Robin Study - Vibration Analysis  

DOE Green Energy (OSTI)

The Gearbox Reliability Collaborative (GRC) at the National Wind Technology Center (NWTC) tested two identical gearboxes. One was tested on the NWTCs 2.5 MW dynamometer and the other was field tested in a turbine in a nearby wind plant. In the field, the test gearbox experienced two oil loss events that resulted in damage to its internal bearings and gears. Since the damage was not severe, the test gearbox was removed from the field and retested in the NWTCs dynamometer before it was disassembled. During the dynamometer retest, some vibration data along with testing condition information were collected. These data enabled NREL to launch a Wind Turbine Gearbox Condition Monitoring Round Robin project, as described in this report. The main objective of this project was to evaluate different vibration analysis algorithms used in wind turbine condition monitoring (CM) and find out whether the typical practices are effective. With involvement of both academic researchers and industrial partners, the project sets an example on providing cutting edge research results back to industry.

Response Predicting LTCC Firing Shrinkage: A Response Surface Analysis Study  

SciTech Connect

The Low Temperature Cofired Ceramic (LTCC) technology is used in a variety of applications including military/space electronics, wireless communication, MEMS, medical and automotive electronics. The use of LTCC is growing due to the low cost of investment, short development time, good electrical and mechanical properties, high reliability, and flexibility in design integration (3 dimensional (3D) microstructures with cavities are possible)). The dimensional accuracy of the resulting x/y shrinkage of LTCC substrates is responsible for component assembly problems with the tolerance effect that increases in relation to the substrate size. Response Surface Analysis was used to predict product shrinkage based on specific process inputs (metal loading, layer count, lamination pressure, and tape thickness) with the ultimate goal to optimize manufacturing outputs (NC files, stencils, and screens) in achieving the final product design the first time. Three (3) regression models were developed for the DuPont 951 tape system with DuPont 5734 gold metallization based on green tape thickness.

Nuclear Spin Lattice Relaxation and Conductivity Studies of the Non-Arrhenius Conductivity Behavior in Lithium Fast Ion Conducting Sulfide Glasses  

DOE Green Energy (OSTI)

As time progresses, the world is using up more of the planet's natural resources. Without technological advances, the day will eventually arrive when these natural resources will no longer be sufficient to supply all of the energy needs. As a result, society is seeing a push for the development of alternative fuel sources such as wind power, solar power, fuel cells, and etc. These pursuits are even occurring in the state of Iowa with increasing social pressure to incorporate larger percentages of ethanol in gasoline. Consumers are increasingly demanding that energy sources be more powerful, more durable, and, ultimately, more cost efficient. Fast Ionic Conducting (FIC) glasses are a material that offers great potential for the development of new batteries and/or fuel cells to help inspire the energy density of battery power supplies. This dissertation probes the mechanisms by which ions conduct in these glasses. A variety of different experimental techniques give a better understanding of the interesting materials science taking place within these systems. This dissertation discusses Nuclear Magnetic Resonance (NMR) techniques performed on FIC glasses over the past few years. These NMR results have been complimented with other measurement techniques, primarily impedance spectroscopy, to develop models that describe the mechanisms by which ionic conduction takes place and the dependence of the ion dynamics on the local structure of the glass. The aim of these measurements was to probe the cause of a non-Arrhenius behavior of the conductivity which has been seen at high temperatures in the silver thio-borosilicate glasses. One aspect that will be addressed is if this behavior is unique to silver containing fast ion conducting glasses. more specifically, this study will determine if a non-Arrhenius correlation time, {tau}, can be observed in the Nuclear Spin Lattice Relaxation (NSLR) measurements. If so, then can this behavior be modeled with a new single distribution of activation energies (DAE) to calculate the corresponding conductivity and relaxation rates as a function of temperature and frequency?

Model for Electron-Beam-Induced Current Analysis of mc-Si Addressing Defect Contrast Behavior in Heavily Contaminated PV Material: Preprint  

DOE Green Energy (OSTI)

Much work has been done to correlate electron-beam-induced current (EBIC) contrast behavior of extended defects with the character and degree of impurity decoration. However, existing models fail to account for recently observed contrast behavior of defects in heavily contaminated mc-Si PV cells. We have observed large increases in defect contrast with decreasing temperature for all electrically active defects, regardless of their initial contrast signatures at ambient temperature. This negates the usefulness of the existing models in identifying defect character and levels of impurity decoration based on the temperature dependence of the contrast behavior. By considering the interactions of transition metal impurities with the silicon lattice and extended defects, we attempt to provide an explanation for these observations. Our findings will enhance the ability of the PV community to understand and mitigate the effects of these types of defects as the adoption of increasingly lower purity feedstocks for mc-Si PV production continues.

Impact of Screening on Behavior During Storage and Cost of Ground Small-Diameter Pine Trees: A Case Study  

DOE Green Energy (OSTI)

Whole comminuted trees are known to self-heat and undergo quality changes during storage. Trommel screening after grinding is a process that removes fines from the screened material and removes a large proportion of high-ash, high-nutrient material. In this study, the trade-off between an increase in preprocessing cost from trommel screening and an increase in quality of the screened material was examined. Fresh lodgepole pine (Pinus contorta) was comminuted using a drum grinder with a 10-cm screen, and the resulting material was distributed into separate fines and overs piles. A third pile of unscreened material, the unsorted pile, was also examined. The three piles exhibited different characteristics during a 6-week storage period. The overs pile was much slower to heat. The overs pile reached a maximum temperature of 56.88 degrees C, which was lower than the maximum reached by the other two piles (65.98 degrees C and 63.48 degrees C for the unsorted and fines, respectively). The overs also cooled faster and dried to a more uniform moisture content and had a lower ash content than the other two piles. Both piles of sorted material exhibited improved airflow and more drying than the unsorted material. Looking at supply system costs from preprocessing through in-feed into thermochemical conversion, this study found that trommel screening reduced system costs by over $3.50 per dry matter ton and stabilized material during storage.

Analysis of Cycling Costs in Western Wind and Solar Integration Study  

DOE Green Energy (OSTI)

The Western Wind and Solar Integration Study (WWSIS) examined the impact of up to 30% penetration of variable renewable generation on the Western Electricity Coordinating Council system. Although start-up costs and higher operating costs because of part-load operation of thermal generators were included in the analysis, further investigation of additional costs associated with thermal unit cycling was deemed worthwhile. These additional cycling costs can be attributed to increases in capital as well as operations and maintenance costs because of wear and tear associated with increased unit cycling. This analysis examines the additional cycling costs of the thermal fleet by leveraging the results of WWSIS Phase 1 study.

Field study of tracer and geochemistry behavior during hydraulic fracturing of a hot dry rock geothermal reservoir  

DOE Green Energy (OSTI)

This study presents tracer and geochemistry data from several hydraulic fracturing experiments at the Fenton Hill, NM, HDR geothermal reservoir. Tracers have been injected at various times during these tests: (1) initially, before any flow communication existed between the wells; (2) shortly after a flow connection was established; and (3) after the outlet flow had increased to its steady state value. An idealized flow model consisting of a combination of main fracture flow paths and fluid leakoff into secondary permeability explains the different tracer response curves for these cases, and allows us to predict the fracture volume of the main paths. The geochemistry during these experiments supports our previously developed models postulating the existence of a high concentration indigenous ''pore fluid.'' Also, the quartz and Na-K-Ca geothermometers have been used successfully to identify the temperatures and depths at which fluid traveled while in the reservoir. The quartz geothermometer is somewhat more reliable because at these high temperatures (about 250/sup 0/C) the injected fluid can come to equilibrium with quartz in the reservoir. The Na-K-Ca geothermometer relies on obtaining a sample of the indigenous pore fluid, and thus is somewhat susceptible to problems of dilution with the injection fluid. 14 refs., 6 figs., 1 tab.

Microcomputer Energy Analysis Studies of Selected Building Types in a Hot, Humid Climatic Zone  

E-Print Network (OSTI)

The DOE-2 building energy analysis computer program has been used in both the design and analysis of new or retrofitted buildings. The combination of ease of use, economy, and the capability of producing a comprehensive thermal analysis has made this tool valuable to the design professional. Recent developments in the microcomputer area make it possible to employ hourly building energy analysis computer models, such a s DOE-2, that were once available only through use of mainframe computers, A microcomputer version of the DOE-2 model is currently available for the study of design and analysis simulations of many building types. Several characteristic buildings emphasizing variations in housing, office/commercial, and school types are being studied. These building types form typical low-scale buildings that are found throughout the region. The discovery of the effects of shape, orientation , mass, and other architectonic elements on energy conservation form a major concern of the survey. A DOE-2 program version adapted for use on a microcomputer demonstrating similar modeling capabilities to the mainframe version is the primary analytical tool used in this study. DOE-2 simulates the heating and cooling loads and the energy consumed by both the primary plant and secondary HVAC energy sources.

Subchronic exposure to low-doses of the nerve agent VX: Physiological, behavioral, histopathological and neurochemical studies  

SciTech Connect

The highly toxic organophosphorous compound VX [O-ethyl-S-(isoporopylaminoethyl) methyl phosphonothiolate] undergoes an incomplete decontamination by conventional chemicals and thus evaporates from urban surfaces, e.g., pavement, long after the initial insult. As a consequence to these characteristics of VX, even the expected low levels should be examined for their potential to induce functional impairments including those associated with neuronal changes. In the present study, we developed an animal model for subchronic, low-dose VX exposure and evaluated its effects in rats. Animals were exposed to VX (2.25 {mu}g/kg/day, 0.05 LD{sub 50}) for three months via implanted mini osmotic pumps. The rapidly attained continuous and marked whole-blood cholinesterase inhibition ({approx} 60%), fully recovered 96 h post pump removal. Under these conditions, body weight, blood count and chemistry, water maze acquisition task, sensitivity to the muscarinic agonist oxotremorine, peripheral benzodiazepine receptors density and brain morphology as demonstrated by routine histopathology, remained unchanged. However, animals treated with VX showed abnormal initial response in an Open Field test and a reduction ({approx} 30%) in the expression of the exocytotic synaptobrevin/vesicle associate membrane protein (VAMP) in hippocampal neurons. These changes could not be detected one month following termination of exposure. Our findings indicate that following a subchronic, low-level exposure to the chemical warfare agent VX some important processes might be considerably impaired. Further research should be addressed towards better understanding of its potential health ramifications and in search of optimal countermeasures.

Case Study Walnut Hill United Methodist Church - Dallas, Texas, Chiller Replacement Analysis  

E-Print Network (OSTI)

In March of 1992 Walnut Hill United Methodist Church in Dallas, Tx. decided that their existing thermal storage and electric reciprocating chiller system were both in need of replacement. After analyzing several options, they chose to install 150 tons of gas-fired double-effect absorption chillers. This case study will show the original HVAC operation cost analysis and compare it to the present day operation costs and it will describe how unexpected changes occurred that caused the initial analysis to be questioned. Finally, this case study will show how today's operational costs are lower than originally projected. This presentation is not about the reasons the church chose this particular system, but about the analysis itself and its accuracy.

A Computational Study on the Thermal-Hydraulic Behavior of Supercritical Carbon Dioxide in Various Printed Circuit Heat Exchanger Designs  

E-Print Network (OSTI)

There has been an ever-increasing demand for power generation, which is predicted to grow as society becomes more advanced. However, tradition fossil fuels are beginning to deplete, and there is a great necessity for alternative fuel sources that will bridge the gap between energy production and consumption. To decrease the high demand alternative fuel sources are gaining in popularity. The supercritical carbon dioxide Brayton power cycle has been proposed as a possible cycle for nuclear and concentrated solar power generation. Two main advantages of having supercritical carbon dioxide are the large property variations and component size associated with power cycle. Forced convection heat transfer of supercritical carbon dioxide in printed circuit heat exchanger geometries were investigated in the following study using a finite volume framework and the FLUENT 12.1 code. The geometries of interest were: non- chamfered zig-zag, chamfered zig-zag, and air foil. Flow through the three geometries was in the horizontal orientation and subject to a heating mode operation. A range of testing conditions were explored, including operating pressures between 7.5 to 10.2 MPa with the mass flux ranging from 326 to 762 kg/m2-s. Due to the turbulent nature of this problem, the k?E with enhanced wall treatment and shear stress transport k?? turbulence models were considered. With this addition a total of 54 simulations were performed. Results indicated that there was an increase in the heat transfer coefficient as the supercritical carbon dioxide reached the pseudocritical temperature, conversely as there was an increase in operating pressure, the heat transfer coefficient decreased. Nevertheless, this increase near the pseudocritical temperature was due to a sharp increase in the specific heat. Mass flux effects indicated that there was an increase in heat transfer as the mass flux was increased. This was due to the increase in Reynolds number near the pseudocritical temperature. Next, pressure losses were investigated for the three geometries. The non-chamfered zig-zag channel had the greatest pressure loss associated with it, while the air foil channel had the least. Based on the results, the ratio of the friction factor to heat transfer for the non-chamfered and chamfered zig-zag geometries were approximately 2.65 and 1.57 times higher than for the air foil, thus leading to the idea that the air foil channel may be best suited for practical applications. Finally, the simulation results were compared to experimental data and existing correlations. Many existing correlations failed to accurately predict the magnitude of heat transfer, although they exhibited a similar trend. A new correlation was developed for the zig-zag geometries based on the numerical data obtained during this investigation and published experimental data. The new correlation is able to predict the maximum heat transfer coefficient within 12.4%.

Statistical Survival Analysis of Fish and Wildlife Tagging Studies; SURPH.1 Manual - Analysis of Release-Recapture Data for Survival Studies, 1994 Technical Manual.  

DOE Green Energy (OSTI)

Program SURPH is the culmination of several years of research to develop a comprehensive computer program to analyze survival studies of fish and wildlife populations. Development of this software was motivated by the advent of the PIT-tag (Passive Integrated Transponder) technology that permits the detection of salmonid smolt as they pass through hydroelectric facilities on the Snake and Columbia Rivers in the Pacific Northwest. Repeated detections of individually tagged smolt and analysis of their capture-histories permits estimates of downriver survival probabilities. Eventual installation of detection facilities at adult fish ladders will also permit estimation of ocean survival and upstream survival of returning salmon using the statistical methods incorporated in SURPH.1. However, the utility of SURPH.1 far exceeds solely the analysis of salmonid tagging studies. Release-recapture and radiotelemetry studies from a wide range of terrestrial and aquatic species have been analyzed using SURPH.1 to estimate discrete time survival probabilities and investigate survival relationships. The interactive computing environment of SURPH.1 was specifically developed to allow researchers to investigate the relationship between survival and capture processes and environmental, experimental and individual-based covariates. Program SURPH.1 represents a significant advancement in the ability of ecologists to investigate the interplay between morphologic, genetic, environmental and anthropogenic factors on the survival of wild species. It is hoped that this better understanding of risk factors affecting survival will lead to greater appreciation of the intricacies of nature and to improvements in the management of wild resources. This technical report is an introduction to SURPH.1 and provides a user guide for both the UNIX and MS-Windows{reg_sign} applications of the SURPH software.

Effects of Trait Behavioral Approach and Inhibition Sensitivity on Behavioral Aggression  

E-Print Network (OSTI)

Behavioral approach sensitivity (BAS) has been found to relate to anger contrary to perspectives positing that BAS is only involved in positive emotions. The present study extends this work by examining relations between behavioral aggression and BAS and behavioral inhibition sensitivity (BIS) measures. Forty-three undergraduate participants were socially ostracized to induce anger, and then given an opportunity to behave aggressively. Higher levels of BAS relate to increased aggressive behavior, whereas higher levels of BIS related to decreased aggressive behavior.

Clarifying the Relationships between Rural Parenting Practices and Child Sedentary Behaviors  

E-Print Network (OSTI)

Childhood obesity is a growing problem in the United States. Though a great body of research has focused on this area, little is still known about the factors that influence this phenomenon in rural settings. Sedentary behavior and parenting factors are just two factors that influence this trend toward obesity. However, even less is known about how the intersection of parenting influences affects child sedentary behaviors in rural communities. This study examines the relationship between parenting factors and child sedentary behaviors within the context of rurality. This study was completed in two parts. Part one consisted of a comprehensive review of the literature that provided background on the current practices and set the stage for the statistical analysis that followed. Part two included the statistical analysis, which focused on examining the relationships between parents’ TV and behavior rules, and child’s sedentary activity behaviors. Pearson correlation and Spearman’s rank were used to assess whether relationships existed between variables. Correlations between weekday and weekend activity and gender were not found to be significant. Also, relationships between rule enforcement and activity were not found to be significant. This study found a glaring gap in the literature that examines how parenting factors influence child sedentary behaviors in rural settings. Also, the statistical analysis revealed that parental rules have no associations with child sedentary activity, despite medium rates of enforcement.

Parametric studies of penetration events : a design and analysis of experiments approach.  

Science Conference Proceedings (OSTI)

A numerical screening study of the interaction between a penetrator and a geological target with a preformed hole has been carried out to identify the main parameters affecting the penetration event. The planning of the numerical experiment was based on the orthogonal array OA(18,7,3,2), which allows 18 simulation runs with 7 parameters at 3 levels each. The strength of 2 of the array allows also for two-factor interaction studies. The seven parameters chosen for this study are: penetrator offset, hole diameter, hole taper, vertical and horizontal velocity of the penetrator, angle of attack of the penetrator and target material. The analysis of the simulation results has been based on main effects plots and analysis of variance (ANOVA), and it has been performed using three metrics: the maximum values of the penetration depth, penetrator deceleration and plastic strain in the penetrator case. This screening study shows that target material has a major influence on penetration depth and penetrator deceleration, while penetrator offset has the strongest effect on the maximum plastic strain.

Lessons Learned on Benchmarking from the International Human Reliability Analysis Empirical Study  

SciTech Connect

The International Human Reliability Analysis (HRA) Empirical Study is a comparative benchmark of the prediction of HRA methods to the performance of nuclear power plant crews in a control room simulator. There are a number of unique aspects to the present study that distinguish it from previous HRA benchmarks, most notably the emphasis on a method-to-data comparison instead of a method-to-method comparison. This paper reviews seven lessons learned about HRA benchmarking from conducting the study: (1) the dual purposes of the study afforded by joining another HRA study; (2) the importance of comparing not only quantitative but also qualitative aspects of HRA; (3) consideration of both negative and positive drivers on crew performance; (4) a relatively large sample size of crews; (5) the use of multiple methods and scenarios to provide a well-rounded view of HRA performance; (6) the importance of clearly defined human failure events; and (7) the use of a common comparison language to “translate” the results of different HRA methods. These seven lessons learned highlight how the present study can serve as a useful template for future benchmarking studies.

An analysis of uranium dispersal and health effects using a Gulf War case study.  

SciTech Connect

The study described in this report used mathematical modeling to estimate health risks from exposure to depleted uranium (DU) during the 1991 Gulf War for both U.S. troops and nearby Iraqi civilians. The analysis found that the risks of DU-induced leukemia or birth defects are far too small to result in an observable increase in these health effects among exposed veterans or Iraqi civilians. Only a few veterans in vehicles accidentally struck by U.S. DU munitions are predicted to have inhaled sufficient quantities of DU particulate to incur any significant health risk (i.e., the possibility of temporary kidney damage from the chemical toxicity of uranium and about a 1% chance of fatal lung cancer). The health risk to all downwind civilians is predicted to be extremely small. Recommendations for monitoring are made for certain exposed groups. Although the study found fairly large calculational uncertainties, the models developed and used are generally valid. The analysis was also used to assess potential uranium health hazards for workers in the weapons complex. No illnesses are projected for uranium workers following standard guidelines; nonetheless, some research suggests that more conservative guidelines should be considered.

Analysis Analysis of Short-Bunch Production with the APS Booster and a Bunch Compressor Michael Borland, AOD/OAG ∗ August 8, 2003 1 Abstract There is significant interest among x-ray scientists in short-pulse x-rays. The x-rays from the APS ring, although very bright, are produced by an electron bunch with an rms length of more than 30 ps. Typically, it is only a linear accelerator that can produce a very short bunch. An idea was brought to my attention by Glenn Decker that might allow us to produce a short bunch using the APS booster. This idea involves extracting the beam from the booster at 3 to 4 GeV, while it is still relatively short, then compressing it with a magnetic bunch compressor. In this note, we present a preliminary analysis of this idea, along with the related idea of using a nonequilibrium beam from the APS photoinjector. 2 Background We will begin with an examination of the ideal result

Utility load management and solar energy. Study background and preliminary market potential analysis  

DOE Green Energy (OSTI)

The large-scale use of electrically assisted solar heating and hot water (solar/electric HHW) systems can have a substantial effect on electric utilities. Under some conditions, peak loads may be increased causing electricity generation costs to rise. However, with appropriate control and thermal storage equipment tied to the HHW system, the timing of the delivery of electricity to the HHW system can be controlled so that it is accomplished during those times of the day when utility supply costs are lowest. In this study various load management schemes for these applications are being investigated to determine their effect on the cost of generating the back-up electric power and on the cost of the required control and storage system. Solar/electric HHW systems are compared to electric-only systems for several utilities and several HHW system designs. The issues underlying the study, the methods of investigation, and the results of the first phase of the study are described. In this phase a preliminary analysis of the maximum market potential for night-time precharge electric-only hot water systems in either utilities was conducted. This analysis indicated that if about 20 to 40 percent of the residential customers used these appliances in a load managed mode, the 10 PM--8 AM valley in the utility load curve would be filled. For combined electric heating and hot water, the corresponding fraction is 6 to 12 percent. It is estimated that in each case, roughly twice the number of residential customers could be accommodated in the valley if solar/electric systems were used instead.

Comparative Analysis of Modeling Studies on China's Future Energy and Emissions Outlook  

SciTech Connect

The past decade has seen the development of various scenarios describing long-term patterns of future Greenhouse Gas (GHG) emissions, with each new approach adding insights to our understanding of the changing dynamics of energy consumption and aggregate future energy trends. With the recent growing focus on China's energy use and emission mitigation potential, a range of Chinese outlook models have been developed across different institutions including in China's Energy Research Institute's 2050 China Energy and CO2 Emissions Report, McKinsey & Co's China's Green Revolution report, the UK Sussex Energy Group and Tyndall Centre's China's Energy Transition report, and the China-specific section of the IEA World Energy Outlook 2009. At the same time, the China Energy Group at Lawrence Berkeley National Laboratory (LBNL) has developed a bottom-up, end-use energy model for China with scenario analysis of energy and emission pathways out to 2050. A robust and credible energy and emission model will play a key role in informing policymakers by assessing efficiency policy impacts and understanding the dynamics of future energy consumption and energy saving and emission reduction potential. This is especially true for developing countries such as China, where uncertainties are greater while the economy continues to undergo rapid growth and industrialization. A slightly different assumption or storyline could result in significant discrepancies among different model results. Therefore, it is necessary to understand the key models in terms of their scope, methodologies, key driver assumptions and the associated findings. A comparative analysis of LBNL's energy end-use model scenarios with the five above studies was thus conducted to examine similarities and divergences in methodologies, scenario storylines, macroeconomic drivers and assumptions as well as aggregate energy and emission scenario results. Besides directly tracing different energy and CO{sub 2} savings potential back to the underlying strategies and combination of efficiency and abatement policy instruments represented by each scenario, this analysis also had other important but often overlooked findings.

Computational Study and Analysis of Structural Imperfections in 1D and 2D Photonic Crystals  

SciTech Connect

Dielectric reflectors that are periodic in one or two dimensions, also known as 1D and 2D photonic crystals, have been widely studied for many potential applications due to the presence of wavelength-tunable photonic bandgaps. However, the unique optical behavior of photonic crystals is based on theoretical models of perfect analogues. Little is known about the practical effects of dielectric imperfections on their technologically useful optical properties. In order to address this issue, a finite-difference time-domain (FDTD) code is employed to study the effect of three specific dielectric imperfections in 1D and 2D photonic crystals. The first imperfection investigated is dielectric interfacial roughness in quarter-wave tuned 1D photonic crystals at normal incidence. This study reveals that the reflectivity of some roughened photonic crystal configurations can change up to 50% at the center of the bandgap for RMS roughness values around 20% of the characteristic periodicity of the crystal. However, this reflectivity change can be mitigated by increasing the index contrast and/or the number of bilayers in the crystal. In order to explain these results, the homogenization approximation, which is usually applied to single rough surfaces, is applied to the quarter-wave stacks. The results of the homogenization approximation match the FDTD results extremely well, suggesting that the main role of the roughness features is to grade the refractive index profile of the interfaces in the photonic crystal rather than diffusely scatter the incoming light. This result also implies that the amount of incoherent reflection from the roughened quarterwave stacks is extremely small. This is confirmed through direct extraction of the amount of incoherent power from the FDTD calculations. Further FDTD studies are done on the entire normal incidence bandgap of roughened 1D photonic crystals. These results reveal a narrowing and red-shifting of the normal incidence bandgap with increasing RMS roughness. Again, the homogenization approximation is able to predict these results. The problem of surface scratches on 1D photonic crystals is also addressed. Although the reflectivity decreases are lower in this study, up to a 15% change in reflectivity is observed in certain scratched photonic crystal structures. However, this reflectivity change can be significantly decreased by adding a low index protective coating to the surface of the photonic crystal. Again, application of homogenization theory to these structures confirms its predictive power for this type of imperfection as well. Additionally, the problem of a circular pores in 2D photonic crystals is investigated, showing that almost a 50% change in reflectivity can occur for some structures. Furthermore, this study reveals trends that are consistent with the 1D simulations: parameter changes that increase the absolute reflectivity of the photonic crystal will also increase its tolerance to structural imperfections. Finally, experimental reflectance spectra from roughened 1D photonic crystals are compared to the results predicted computationally in this thesis. Both the computed and experimental spectra correlate favorably, validating the findings presented herein.

A stochastic feasibility study of Texas ethanol production: analysis of Texas Legislature ethanol subsidy proposal  

E-Print Network (OSTI)

The recent resurgence of interest in ethanol production has prompted the Texas State Legislature to investigate the feasibility of ethanol production in Texas. The reasons for the increased interest in ethanol production could possibly relate to depressed commodity prices, gasoline price volatility, environmental regulations and a renewed push towards increased fuel sufficiently given national and world events following September 11, 2001. Past feasibility studies have failed to incorporate the risk of input and output prices in their analyses. Furthermore, it is evident from the literature, that unrealistic values were used in many of the studies, to perhaps, entice prospective investors in providing capital for the construction and operation of the ethanol facilities. This study provides an unbiased, stochastic simulation feasibility study incorporating the risks of ethanol, corn, dry distillers grains (DDGS), soybean meal, electricity, and natural gas prices on three size facilities in Texas. In addition, four different scenarios were included incorporating four levels of the proposed Texas State Producer Grant into the feasibility study. Those levels were the $0.00, $0.10, $0.20, and $0.30/gal on the first 30 million gallons per year (MMGPY) of production for each registered plant. Rather than assuming point values for input variables and providing a deterministic analysis, the advantage of this study is that it provides a feasibility study that includes risks of input and output prices in its results. For each of the three size facilities analyzed (15, 30, and 80 MMGPY) the results of probability of negative cash flows and simple statistics, probability of dividend payments and simple statistics, present value of ending owners equity in 2022, net present value, certainty equivalents and absolute certainty equivalents risk premiums of net present value are described in the study. The study found that neither the 15, 30, or the 80 MMGPY facilities would be feasible in Texas. The facilities have little chance of economic success under the best scenario ($0.30/gal) and all have a zero percent chance of maintaining beginning equity.

Case study: Visual analysis of complex, time-dependent simulation results of a diesel exhaust system  

E-Print Network (OSTI)

In previous work we have presented visualization techniques that provide engineers with a high degree of interactivity and flexibility for analyzing large, time-dependent, and high-dimensional data sets resulting from CFD (computational fluid dynamics) simulations. In this case study we apply our techniques in the fields of the automotive engineering industry and demonstrate how users benefit from using them during their routine analysis, as well as for exploring new phenomena. For coping with some of the special requirements in this application, we adapted and extended parts of the system. A comparison of two related cases of a diesel exhaust system is presented, and some important questions about these cases are addressed. 1.

Case study analysis of biomass burning plumes observed over Brazil during SAMBBA, September 2012  

Science Conference Proceedings (OSTI)

Biomass burning is a huge source of atmospheric aerosols and is poorly understood leading to large uncertainties in estimates of radiative forcing of climate. Aerosols have both a direct effect on climate by reflecting and absorbing solar radiation and an indirect effect by acting as cloud condensation nuclei (CCN) and ice nuclei (IN). Biomass burning aerosols are produced from burning of vegetation with the vast majority occurring in the tropics. This research presents data collected during the aircraft campaign of the South American Biomass Burning Analysis (SAMBBA) project during September and October 2012. A smouldering rainforest fire and a flaming savannah-like fire were selected for in-depth case studies of the atmospheric plume constituents and provide a comparison between the two fire types. The physiochemical characterization of the two plumes are identified

Liquid metal cooled solar central receiver feasibility study and heliostat field analysis. Final report, Part II  

DOE Green Energy (OSTI)

Four studies are presented, the first two of which are based on a specific design for a water/steam commercial 100 MW/sub e/ Solar Tower System. The first of these uses the RCELL computer program, which provides a cellwise method for the economic optimization of central receiver systems, to compare performance for several latitudes, field slopes, tower heights, heliostat costs, land costs, and input figures of merit. Using the systems design studies for the 100 MW/sub e/ unit, the second study performs a detailed net energy analysis on capital energy required to build the thermal collection component, including 6 hours of storage. Also determined is the Energy Amplification Factor, which measures the number of times the energy incorporated in the plant can be replicated during its lifetime. The third study provides a means for calculating the sun's position as a function of time. The fundamental reference frames for observing celestial objects are defined, and basic notions of orbits and time reckoning are explained. Series solutions for the equation of time and for the equation of the center are given. Phenomena affecting the sun's position and the errors which result when their effects are disregarded are summarized. A computer program to accurately locate the sun was written. The effects that two different sun tracker programs have on insolation prediction are compared. The fourth study describes and models the sodium heat engine, a continuous isothermal expansion engine for sodium vapor. The heart of the machine is beta''-alumina, a refractory material remarkable for its high conductivity of sodium ions. (LEW)

Lower Columbia River and Estuary Ecosystem Restoration Program Reference Site Study: 2011 Restoration Analysis - FINAL REPORT  

SciTech Connect

The Reference Site (RS) study is part of the research, monitoring, and evaluation (RME) effort developed by the Action Agencies (Bonneville Power Administration [BPA], U.S. Army Corps of Engineers, Portland District [USACE], and U.S. Bureau of Reclamation) in response to Federal Columbia River Power System (FCRPS) Biological Opinions (BiOp). While the RS study was initiated in 2007, data have been collected at relatively undisturbed reference wetland sites in the LCRE by PNNL and collaborators since 2005. These data on habitat structural metrics were previously summarized to provide baseline characterization of 51 wetlands throughout the estuarine and tidal freshwater portions of the 235-km LCRE; however, further analysis of these data has been limited. Therefore, in 2011, we conducted additional analyses of existing field data previously collected for the Columbia Estuary Ecosystem Restoration Program (CEERP) - including data collected by PNNL and others - to help inform the multi-agency restoration planning and ecosystem management work underway in the LCRE.

SAID Partial Wave Analyses from CNS DAC (Center for Nuclear Studies Data Analysis Center)  

DOE Data Explorer (OSTI)

George Washington University (GW) has one of the largest university-based nuclear-physics groups in the nation. Many of the current and future projects are geared to Thomas Jefferson National Accelerator Facility (JLab) at Newport News, VA. JLab is the world's premier electron accelerator for nuclear physics, and GW is one of the charter members of the governing body of JLab, the Southeastern Universities Research Association (SURA). The George Washington Data Analysis Center (DAC) was created in 1998 by an agreement among the Department of Energy, Jefferson Lab, and the GW Center for Nuclear Studies.The activities of the DAC fall into four distinct categories: 1) Performing partial-wave analyses of fundamental two- and three-body reactions; 2) Maintenance of databases associated with these reactions; 3) Development of software to disseminate DAC results (as well as the results of competing model-independent analyses and potential approaches); and 4) Phenomenological and theoretical investigations which bridge the gap between theory and experiment; in particular, the extraction of N* and D * hadronic and electromagnetic couplings. Partial Wave Analyses (and the associated databases) available at GW are: Pion-Nucleon, Kaon-Nucleon, Nucleon-Nucleon, Pion Photoproduction, Pion Electroproduction, Kaon Photoproduction, Eta Photoproduction, Eta-Prime Photoproduction, Pion-Deuteron (elastic), and Pion-Deuteron to Proton+Proton.

Aerobic enhanced oil recovery: analysis of the mechanisms and a pilot study  

E-Print Network (OSTI)

The technique that uses microorganisms to improve oil production in petroleum reservoirs is known as microbial enhanced oil recovery (MEOR). Aerobic microbial enhanced oil recovery is a method which is based on stimulating indigenous oil degrading bacteria by introducing oxygen (air) and nutrients into the injection water in an existing water flood. The primary emphasis is to promote biological growth in the oil/ water interface, which reduces the interfacial tension and mobilizes the oil. This process is proven to work in laboratory studies, and successful field tests have been reported in USSR. A pilot test on AMEOR has been initiated in the North Brock field in Oklahoma. The treatment, which consists of a continuous injection of air together with an appropriate nutrient supply, has been going on for seven months. So far no increase in oil production has been observed in the full field scale. However, well tests performed on each production well show an increase in oil production from two wells. This increase does not have any effect on the total oil production due to decline periods in the other wells. The most positive observation in the field test is an increase in the differential pressure observed right after the start of oxygen injection. This may be a result of reduced permeability to water in the oil bank, indicating an oil mobilization process in the reservoir. The same effect has also been observed in the laboratory core studies. The process is also proven to be time dependent and independent of the number of pore volumes flooded. It is concluded that it is too early in the process to experience any incremental oil production. The pressure increase may indicate that a mobilization process is going on and that it will only be a matter of time before any additional oil will be experienced in the field. This research involves an analysis of the pilot study in the North Brock field, in addition to a description of the AMEOR technique, effects and limitations. A comparison to other conventional MEOR techniques is also given.

Verification of the coupled fluid/solid transfer in a CASL grid-to-rod-fretting simulation : a technical brief on the analysis of convergence behavior and demonstration of software tools for verification.  

SciTech Connect

For a CASL grid-to-rod fretting problem, Sandia's Percept software was used in conjunction with the Sierra Mechanics suite to analyze the convergence behavior of the data transfer from a fluid simulation to a solid mechanics simulation. An analytic function, with properties relatively close to numerically computed fluid approximations, was chosen to represent the pressure solution in the fluid domain. The analytic pressure was interpolated on a sequence of grids on the fluid domain, and transferred onto a separate sequence of grids in the solid domain. The error in the resulting pressure in the solid domain was measured with respect to the analytic pressure. The error in pressure approached zero as both the fluid and solids meshes were refined. The convergence of the transfer algorithm was limited by whether the source grid resolution was the same or finer than the target grid resolution. In addition, using a feature coverage analysis, we found gaps in the solid mechanics code verification test suite directly relevant to the prototype CASL GTRF simulations.

Modeling and sensitivity analysis study of the reduction of NO{sub x} by HNCO  

SciTech Connect

A chemical mechanism for the reduction of NO{sub x} by HNCO has been constructed to allow for the modeling of NO{sub x} in exhausts typical of natural gas combustion (RAPRENOx process). The reduction was modeled assuming plug flow, and either isothermal combustion or constant pressure adiabatic combustion. Variables were initial concentrations of NO, NO{sub 2}, CO, CH{sub 4}, H{sub 2}, and HNCO as well as initial temperatures. Exhaust residence time was nominally 1 s. Reduction was not achieved for prototypical ``natural gas exhaust`` for a reasonable residence time. Radical generation is crucial for reduction. H{sub 2} addition enhanced ignition and reduction. The final combustion temperature determines where NO{sub x} reduction ceases and NO{sub x} production increases. Reduction increases with HNCO, and breakthrough of NH{sub 3} and HNCO increses as well. N{sub 2}O production is due to NCO + NO, but the reduction of NO also occurs through reactions associated with the Thermal De-NOx chemistry. NH{sub 3} production and reactions are important to the reduction of NO. Sensitivity analysis under easy ignition conditions indicated that the same reactions involving nitrogen species, NH{sub 2} and NNH, important in De-NOx, are important when HNCO is used to reduce NO{sub x}. A real combustion exhaust would contain radicals, but it would be neither isothermal nor adiabatic, and heat release and loss would accompany the reduction process. Three-body recombination reactions are important and need further study.(DLC)

Study of Possible Applications of Currently Available Building Information Modeling Tools for the Analysis of Initial Costs and Energy Costs for Performing Life Cycle Cost Analysis  

E-Print Network (OSTI)

The cost of design, construction and maintenance of facilities is on continual rise. The demand is to construct facilities which have been designed by apply life cycle costing principles. These principles have already given strong decision making power to the manufacturing industry. The need to satisfy the environmental sustainability requirements, improve operational effectiveness of buildings and apply value engineering principles has increased the dependency on life cycle costing analysis. The objective is to obtain economically viable solutions by analyzing the alternatives during the design of a building. Though the LCCA process is able to give the desired results, it does have some problems which have stood as hindrances to the more widespread use of the LCCA concept and method. The literature study has highlighted that the problem areas are the lack of frameworks or mechanisms for collecting and storing data and the complexity of LCCA exercise, which involves the analysis of a thousand of building elements and a number of construction-type options and maintenance activities for each building element at detailed design stages. Building Information Modeling has been able to repeatedly answer the questions raised by the AEC industry. The aim of this study is to identify the areas where BIM can be effectively applied to the LCCA process and become a part of the workflow. In this study, initially four LCCA case studies are read and evaluated from the point of view of understanding the method in which the life cycle costing principles have been applied. The purpose, the type alternatives examined, the process of analysis, the type of software used and the results are understood. An attempt has been carried out to understand the workflow of the LCCA process. There is a confidence that Building Information Modeling is capable of handling changes during the design, construction and maintenance phases of the project. Since applying changes to any kind of information of the building during LCC analysis forms the core, it has become necessary to use computer building models for examining these changes. The building modeling softwares are enumerated. The case studies have highlighted that the evaluation of the alternatives are primarily to achieve energy efficient solutions for the buildings. Applying these solutions involves high initial costs. The return on investment is the means by which these solutions become viable to the owners of the facilities. This is where the LCCA has been applied. Two of the important cost elements of the LCC analysis are initial costs and the operating costs of the building. The collaboration of these modeling tools with other estimating software where the initial costs of the building can be generated is studied. The functions of the quantity take-off tools and estimating tools along with the interoperability between these tools are analyzed. The operating costs are generated from the software that focuses on sustainability. And the currently used tools for performing the calculations of the life cycle costing analysis are also observed. The objective is to identify if the currently available BIM tools and software can help in obtaining LCCA results and are able to offset the hindrances of the process. Therefore, the software are studied from the point of view of ease of handling data and the type of data that can be generated. Possible BIM workflows are suggested depending on the functions of the software and the relationship between them. The study has aimed at taking a snapshot the current tools available which can aid the LCCA process. The research is of significance to the construction industry as it forms a precursor to the application of Building Information Modeling to the LCCA process as it shows that it has the capacity of overcoming the obstacles for life cycle costing. This opens a window to the possibility of applying BIM to LCCA and furthering this study.

Financial Analysis of Incentive Mechanisms to Promote Energy Efficiency: Case Study of a Prototypical Southwest Utility  

Science Conference Proceedings (OSTI)

Many state regulatory commissions and policymakers want utilities to aggressively pursue energy efficiency as a strategy to mitigate demand and energy growth, diversify the resource mix, and provide an alternative to building new, costly generation. However, as the National Action Plan for Energy Efficiency (NAPEE 2007) points out, many utilities continue to shy away from aggressively expanding their energy efficiency efforts when their shareholder's fundamental financial interests are placed at risk by doing so. Thus, there is increased interest in developing effective ratemaking and policy approaches that address utility disincentives to pursue energy efficiency or lack of incentives for more aggressive energy efficiency efforts. New regulatory initiatives to promote increased utility energy efficiency efforts also affect the interests of consumers. Ratepayers and their advocates are concerned with issues of fairness, impacts on rates, and total consumer costs. From the perspective of energy efficiency advocates, the quid pro quo for utility shareholder incentives is the obligation to acquire all, or nearly all, achievable cost-effective energy efficiency. A key issue for state regulators and policymakers is how to maximize the cost-effective energy efficiency savings attained while achieving an equitable sharing of benefits, costs and risks among the various stakeholders. In this study, we modeled a prototypical vertically-integrated electric investor-owned utility in the southwestern US that is considering implementing several energy efficiency portfolios. We analyze the impact of these energy efficiency portfolios on utility shareholders and ratepayers as well as the incremental effect on each party when lost fixed cost recovery and/or utility shareholder incentive mechanisms are implemented. A primary goal of our quantitative modeling is to provide regulators and policymakers with an analytic framework and tools that assess the financial impacts of alternative incentive approaches on utility shareholders and customers if energy efficiency is implemented under various utility operating, cost, and supply conditions.We used and adapted a spreadsheet-based financial model (the Benefits Calculator) which was developed originally as a tool to support the National Action Plan for Energy Efficiency (NAPEE). The major steps in our analysis are displayed graphically in Figure ES- 1. Two main inputs are required: (1) characterization of the utility which includes its initial financial and physical market position, a forecast of the utility?s future sales, peak demand, and resource strategy to meet projected growth; and (2) characterization of the Demand-Side Resource (DSR) portfolio ? projected electricity and demand savings, costs and economic lifetime of a portfolio of energy efficiency (and/or demand response) programs that the utility is planning or considering implementing during the analysis period. The Benefits Calculator also estimates total resource costs and benefits of the DSR portfolio using a forecast of avoided capacity and energy costs. The Benefits Calculator then uses inputs provided in the Utility Characterization to produce a ?business-as usual? base case as well as alternative scenarios that include energy efficiency resources, including the corresponding utility financial budgets required in each case. If a decoupling and/or a shareholder incentive mechanism are instituted, the Benefits Calculator model readjusts the utility?s revenue requirement and retail rates accordingly. Finally, for each scenario, the Benefits Calculator produces several metrics that provides insights on how energy efficiency resources, decoupling and/or a shareholder incentive mechanism impacts utility shareholders (e.g. overall earnings, return on equity), ratepayers (e.g., average customer bills and rates) and society (e.g. net resource benefits).

Bio-Climatic Analysis and Thermal Performance of Upper Egypt A Case Study Kharga Region  

E-Print Network (OSTI)

As a result of the change and development of Egyptian society, Egyptian government has focused its attention of comprehensive development to various directions. One of these attentions is housing, construction and land reclamation in desert and Upper Egypt. In the recent century the most attentions of the government is the creation of new wadi parallel to Nile wadi in the west desert. Kharga Oasis is 25 degrees 26'56?North latitude and 30 degrees 32'24?East longitude. This oasis, is the largest of the oases in the westren desert of Egypt. It required the capital of the new wadi (Al Wadi Al Gadeed Government). The climate of this oasis is caricaturized by; aridity, high summer daytime temperature, large diurnal temperature variation, low relative humidity and high solar radiation. In such conditions, man losses his ability to work and to contribute effectively in the development planning due to the high thermal stress affected on him. In designing and planning in this region, it is necessary not only to understand the needs of the people but to create an indoor environment which is suitable for healthy, pleasant, and comfortable to live and work in it. So, efforts have been motivated towards the development of new concepts for building design and urban planning to moderate the rate, direction and magnitudes of heat flow. Also, reduce or if possible eliminate the energy expenditure for environmental control. In order to achieve this, attention has to be focused on building design to improve its thermal performance, which is a function of building form, orientation, location, and materials used and produce comfortable environmental conditions without increasing of energy consumed. This can be valid in three stage, the first one by using the bio-climatic analysis, the 2nd one by the handle and simplified calculation methods (Uvalue, Thermal time constant, and Degree day), and the 3rd one is by the simulation method. The admittance procedure is a technique for estimating cooling/heating load and temperature changes under cyclic conditions by using the thermal characteristics (Y-value, lambda, phi, Sf) of the building structure. It dependent on determining the daily means value and the swing about the mean. The admittance method is used and a computer program is developed to predict the heating and cooling load as well as the environmental air temperature by the author. This study deals with the bio-climatic analysis and thermal performance of building in Kharga Oasis. The results show that, the air catcher, court and Passive cooling systems (evaporative cooling), maintained the indoor climate in the thermal human comfort zone during the hottest period under the effect of climatic conditions of Kharga. Also shading devices, and suitable orientation achieve a harmony building with environment. Using insulating materials in exposed walls and roof save energy by about 60%. The Thermal insulation thicknesses between 0.03-0.05m for exposed walls and 0.05m for exposed roofs are suitable to valid the required thermal resistance in Kharga Oasis according to the Egyptian Residential Buildings Energy Code, ECP 306-2005.

Evolution of Phase Transformation Behavior in Li(Mn1.5Ni0.5)O4 Cathodes Studies By In Situ XRD  

Science Conference Proceedings (OSTI)

Li(Mn1.5Ni0.5)O4 (MNO) is promising spinel cathode material for lithium ion batteries (LIB) due to its increased intercalation potential and improved capacity retention compared to LiMn2O4. Still, improvements to this materials performance must be achieved before MNO is a viable option for commercial LIB cells. In situ X-ray diffraction of Li(Mn1.5Ni0.5)O4 was performed using a novel electrochemical cell based on coin cell hardware. A diffractogram of the pristine material showed a spinel structure with a Ni2+ oxidation state. As the cell was charged through its 4.75V plateau, a transition between spinels with Ni2+, Ni3+, and Ni4+ oxidation was observed. As the oxidation stage on the nickel increased the lattice parameter of the corresponding spinel was reduced. As discharged ensued the spinel reversed its phases change until only the Ni2+ spinel was present. When discharge reached the 2.75V plateau a tetragonal spinel phase was formed, which upon subsequent cell charging was completely converted back to a cubic spinel phase. Lattice parameter changes of each phase were calculated and showed a characteristic strain release during phase changes. After 15 full cycles the transition between these phases was no longer complete and the formation of the tetragonal spinel phase was no longer detected. A discussion of how these cycle-induced changes to phase transition behavior relate to capacity fade and overall cell performance is presented.

Colossal magnetoresistive (CMR) manganites are a class of materials under study for future spintronic applications such as nonvolatile magnetic computer memory (MRAM). Researchers have recently used several soft x-ray spectroscopies at the ALS to study a prototypical CMR manganite as it was heated past its Curie temperature-the point at which the material ceases to be magnetic. They were able to observe the formation of polarons: electrons whose interaction with the lattice creates a deformation (energy well) that traps the electron, as a pocket on a pool table traps a billiard ball. For the first time, this provided a direct look inside polaron formation in a CMR material, indicating that electron localization as polarons is a defining characteristic of all CMR materials.

URANIUM METAL POWDER PRODUCTION, PARTICLE DISTRIBUTION ANALYSIS, AND REACTION RATE STUDIES OF A HYDRIDE-DEHYDRIDE PROCESS  

E-Print Network (OSTI)

Work was done to study a hydride-dehydride method for producing uranium metal powder. Particle distribution analysis was conducted using digital microscopy and grayscale image analysis software. The particle size was found to be predominantly in the 40 ?m range, which agreed with previous work. The effects of temperature, pressure, and time on the reaction fraction of powder were measured by taking experimental data. The optimum hydride temperature for the system was found to be 233.4°C. Higher gas pressures resulted in higher reaction fractions, over the range studied. For the sample parameters studied, a time of 371 minutes was calculated to achieve complete powderization. System design parameters for commercialization are proposed.

New Research on Jamming Behavior Expands Understanding  

NLE Websites -- All DOE Office Websites (Extended Search)

New Research on Jamming Behavior New Research on Jamming Behavior Expands Understanding New Research on Jamming Behavior Expands Understanding Print Tuesday, 22 October 2013 00:00 Summary Slide One of the most satisfying aspects of condensed matter physics is that a variety of condensed matter systems show universal behavior-behavior that appears to be common to a wide variety of unrelated systems. The phenomenon of "jamming," which is similar to what happens to vehicles in traffic jams, fits into this category. Recent ALS research has revealed that even magnetic domains behave very much like other granular material systems, and their dynamical behavior mimics the universal characteristics of several jammed systems. Jamming Transitions Give Insight into Behaviors Recently, there has been much interest in jamming transitions, which were originally studied as a way to discuss the behavior of granular materials or dense assemblies of particles but have been eventually proposed as a more general and unified way of looking at dynamics of systems as diverse as structural glasses, entangled polymers, colloidal gels, supercooled liquids, and the like. Jamming is the physical process by which some materials become rigid with increasing density. Jamming occurs when the particle densities or entanglements are such that the motions of the individual particles become very restricted so that they slow down. The fluctuations that occur in a jammed system with long-range interactions are cooperative fluctuations where a local displacement causes an inhomogeneity, which is correlated with a displacement in another region.

Image analysis algorithms for estimating porous media multiphase flow variables from computed microtomography data: a validation study  

Science Conference Proceedings (OSTI)

Image analysis of three-dimensional microtomographic image data has become an integral component of pore scale investigations of multiphase flow through porous media. This study focuses on the validation of image analysis algorithms for identifying phases and estimating porosity, saturation, solid surface area, and interfacial area between fluid phases from gray-scale X-ray microtomographic image data. The data used in this study consisted of (1) a two-phase high precision bead pack from which porosity and solid surface area estimates were obtained and (2) three-phase cylindrical capillary tubes of three different radii, each containing an air-water interface, from which interfacial area was estimated. The image analysis algorithm employed here combines an anisotropic diffusion filter to remove noise from the original gray-scale image data, a k-means cluster analysis to obtain segmented data, and the construction of isosurfaces to estimate solid surface area and interfacial area. Our method was compared with laboratory measurements, as well as estimates obtained from a number of other image analysis algorithms presented in the literature. Porosity estimates for the two-phase bead pack were within 1.5% error of laboratory measurements and agreed well with estimates obtained using an indicator kriging segmentation algorithm. Additionally, our method estimated the solid surface area of the high precision beads within 10% of the laboratory measurements, whereas solid surface area estimates obtained from voxel counting and two-point correlation functions overestimated the surface area by 20--40%. Interfacial area estimates for the air-water menisci contained within the capillary tubes were obtained using our image analysis algorithm, and using other image analysis algorithms, including voxel counting, two-point correlation functions, and the porous media marching cubes. Our image analysis algorithm, and other algorithms based on marching cubes, resulted in errors ranging from 1% to 20% of the analytical interfacial area estimates, whereas voxel counting and two-point correlation functions overestimated the analytical interfacial area by 20--40%. In addition, the sensitivity of the image analysis algorithms on the resolution of the microtomographic image data was investigated, and the results indicated that there was little or no improvement in the comparison with laboratory estimates for the resolutions and conditions tested.

Analyzing the Impact of Residential Building Attributes, Demographic and Behavioral Factors on Natural Gas Usage  

SciTech Connect

This analysis examines the relationship between energy demand and residential building attributes, demographic characteristics, and behavioral variables using the U.S. Department of Energy’s Residential Energy Consumption Survey 2005 microdata. This study investigates the applicability of the smooth backfitting estimator to statistical analysis of residential energy consumption via nonparametric regression. The methodology utilized in the study extends nonparametric additive regression via local linear smooth backfitting to categorical variables. The conventional methods used for analyzing residential energy consumption are econometric modeling and engineering simulations. This study suggests an econometric approach that can be utilized in combination with simulation results. A common weakness of previously used econometric models is a very high likelihood that any suggested parametric relationships will be misspecified. Nonparametric modeling does not have this drawback. Its flexibility allows for uncovering more complex relationships between energy use and the explanatory variables than can possibly be achieved by parametric models. Traditionally, building simulation models overestimated the effects of energy efficiency measures when compared to actual "as-built" observed savings. While focusing on technical efficiency, they do not account for behavioral or market effects. The magnitude of behavioral or market effects may have a substantial influence on the final energy savings resulting from implementation of various energy conservation measures and programs. Moreover, variability in behavioral aspects and user characteristics appears to have a significant impact on total energy consumption. Inaccurate estimates of energy consumption and potential savings also impact investment decisions. The existing modeling literature, whether it relies on parametric specifications or engineering simulation, does not accommodate inclusion of a behavioral component. This study attempts to bridge that gap by analyzing behavioral data and investigate the applicability of additive nonparametric regression to this task. This study evaluates the impact of 31 regressors on residential natural gas usage. The regressors include weather, economic variables, demographic and behavioral characteristics, and building attributes related to energy use. In general, most of the regression results were in line with previous engineering and economic studies in this area. There were, however, some counterintuitive results, particularly with regard to thermostat controls and behaviors. There are a number of possible reasons for these counterintuitive results including the inability to control for regional climate variability due to the data sanitization (to prevent identification of respondents), inaccurate data caused by to self-reporting, and the fact that not all relevant behavioral variables were included in the data set, so we were not able to control for them in the study. The results of this analysis could be used as an in-sample prediction for approximating energy demand of a residential building whose characteristics are described by the regressors in this analysis, but a certain combination of their particular values does not exist in the real world. In addition, this study has potential applications for benefit-cost analysis of residential upgrades and retrofits under a fixed budget, because the results of this study contain information on how natural gas consumption might change once a particular characteristic or attribute is altered. Finally, the results of this study can help establish a relationship between natural gas consumption and changes in behavior of occupants.

Energy conservation standards for new federal residential buildings: A decision analysis study using relative value discounting  

SciTech Connect

This report presents a reassessment of the proposed standard for energy conservation in new federal residential buildings. The analysis uses the data presented in the report, Economic Analysis: In Support of Interim Energy Conservation Standards for New Federal Residential Buildings (June 1988)-to be referred to as the EASIECS report. The reassessment differs from that report in several respects. In modeling factual information, it uses more recent forecasts of future energy prices and it uses data from the Bureau of the Census in order to estimate the distribution of lifetimes of residential buildings rather than assuming a hypothetical 25-year lifetime. In modeling social preferences decision analysis techniques are used in order to examine issues of public values that often are not included in traditional cost-benefit analyses. The present report concludes that the public would benefit from the proposed standard. Several issues of public values regarding energy use are illustrated with methods to include them in a formal analysis of a proposed energy policy. The first issue places a value on costs and benefits that will occur in the future as an irreversible consequence of current policy choices. This report discusses an alternative method, called relative value discounting which permits flexible discounting of future events-and the possibility of placing greater values on future events. The second issue places a value on the indirect benefits of energy savings so that benefits accrue to everyone rather than only to the person who saves the energy. This report includes non-zero estimates of the indirect benefits. The third issue is how the costs and benefits discussed in a public policy evaluation should be compared. In summary, selection of individual projects with larger benefit to cost ratios leads to a portfolio of projects with the maximum benefit to cost difference. 30 refs., 6 figs., 16 tabs. (JF)

Mechanical Behavior of Indium Nanostructures Print Mechanical Behavior of Indium Nanostructures Print Indium is a key material in lead-free solder applications for microelectronics due to its excellent wetting properties, extended ductility, and high electrical conductivity. With the size of electronic devices continuing to shrink and the promise of indium-based nanotechnologies, it is important to develop a fundamental understanding of this material's small-scale mechanical properties and reliability. Researchers from the University of Waterloo, California Institute of Technology, and Los Alamos National Laboratory have collaborated with a team at ALS Beamline 12.3.2 to investigate the small-scale mechanics of indium nanostructures. Scanning x-ray microdiffraction (μSXRD) studies revealed that the indium microstructure is typical of a well-annealed metal, containing very few initial dislocations and showing close-to-theoretical strength.

Neurobiology of Bat Vocal Behavior  

E-Print Network (OSTI)

Vocal plasticity is presumed to be a key element underlying the evolution of human speech and language, but the mechanisms and neuroanatomical basis for this plasticity remain largely unknown. The Mexican free-tailed bat, Tadarida brasiliensis, presents a unique opportunity to advance our understanding of the evolution and neurobiology of mammalian vocal communication because this animal displays elements of vocal complexity and plasticity that are more sophisticated than any mammal other than humans, including non-human primates. Current models of vocal control in mammals do not account for the vocal complexity of free-tailed bats. The purpose of this dissertation is to fill that gap in knowledge by identifying a possible neuronal basis for vocal complexity in free-tailed bats. This will be achieved by 1) providing a detailed analysis of the free-tailed bat’s vocal behaviors, 2) mapping the distribution of neurotransmitter receptor types suspected of involvement in vocal control, 3) identifying brain regions that exhibit increased neuronal activity during vocalizing, and 4) pharmacologically manipulating putative vocal control regions to confirm and characterize their function in vocalizing. Analysis of Tadarida’s vocal behavior indicated that they have a vast vocal repertoire, including many different call types, context-dependent sensory-feedback driven vocal plasticity, and syntactically-organized stereotyped songs. Their vocal behavior changed seasonally, so I mapped the distribution of melatonin binding sites in the brain, finding high densities in the striatum, similar to dopamine receptor distribution. I then used immunohistochemical labeling of the immediate early gene cfos to map neuronal activation in brains of highly vocal bats to find ROIs activated by vocal production. This technique not only identified all previously known regions of the mammalian vocal motor pathway but also revealed activity in novel brain regions that could potentially account for vocal plasticity, including a localized region of the basal ganglia, the dorsolateral caudate nucleus, and the anterior cingulate region of the frontal cortex. Pharmacological excitation of these regions evoked complex vocal sequences similar to the songs recorded in the field and lab. These results support the hypothesis that the mammalian basal ganglia may play a crucial role in the plasticity and complexity of mammalian vocal behaviors.

A Study on Experiment and Numerical Analysis for Disclosing Shell Wall Thinning of a Feedwater Heater  

Science Conference Proceedings (OSTI)

Feedwater heaters of many nuclear power plants have recently experienced severe wall thinning damage, which will increase as operating time progresses. Several nuclear power plants in Korea have experienced wall thinning damage in the area around the impingement baffle - installed downstream of the high pressure turbine extraction steam line - inside number 5A and 5B feedwater heaters. At that point, the extracted steam from the high pressure turbine is two phase fluid at high temperature, high pressure, and high speed. Since it flows in reverse direction after impinging the impingement baffle, the shell wall of the number 5 high pressure feedwater heater may be affected by flow-accelerated corrosion. This paper describes the comparisons between the numerical analysis results using the FLUENT code and the down scale experimental data in an effort to determine root causes of the shell wall thinning of the high pressure feedwater heaters. The numerical analysis and experimental data were also confirmed by actual wall thickness measured by an ultrasonic test. (authors)

Mission analysis of photovoltaic solar energy conversion. Volume IV. Supplementary studies  

DOE Green Energy (OSTI)

A discussion is presented of the most significant problems associated with the production and deployment of photovoltaic arrays. The principal chemical compounds to be used in the manufacture of silicon, gallium arsenide, and cadmium sulfide photovoltaic arrays are discussed with respect to physical and chemical properties, sources of the raw materials required to extract or synthesize these materials, the methods of manufacture, storage and handling in large quantities, transportation restrictions, spills, leaks, ignition and explosion. A discussion of safety hazards associated with the finished products is followed by an analysis of the toxicological properties of all raw, refined, and finished chemical species involved. The principal tool used in the evaluation of incentive strategies was a new Public Utility Financial Analysis and Planning Model which is described in some detail. After adaptation to match the characteristics of photovoltaic plants, it was used in the comparative evaluation of six different incentive strategies. The candidate strategies, the rationale for their selection, and the results of the comparative evaluation are presented. An account is given of an attempt to assess the full non-internalized costs of coal-fired power generation. A detailed description is given of the various damage elements and their associated societal costs for coal production, coal transportation, and coal-fired power generation. (MHR)

Neutron Resonance Transmission Analysis (NRTA): Initial Studies of a Method for Assaying Plutonium in Spent Fuel  

SciTech Connect

Neutron Resonance Transmission Analysis (NRTA) is an analytical technique that uses neutrons to assay the isotopic content of bulk materials. The technique uses a pulsed accelerator to produce an intense, short pulse of neutrons in a time-of-flight configuration. These neutrons, traveling at different speeds according to their energy, can be used to interrogate a spent fuel (SF) assembly to determine its plutonium content. Neutron transmission through the assembly is monitored as a function of neutron energy (time after the pulse), similar to the way neutron cross-section data is often collected. The transmitted neutron intensity is recorded as a function of time, with faster (higher-energy) neutrons arriving first and slower (lower-energy) neutrons arriving later. The low-energy elastic scattering and absorption resonances of plutonium and other isotopes modulate the transmitted neutron spectrum. Plutonium content in SF can be determined by analyzing this attenuation. Work is currently underway at Idaho National Laboratory, as a part of United States Department of Energy's Next Generation Safeguards Initiative (NGSI), to investigate the NRTA technique and to assess its feasibility for quantifying the plutonium content in SF and for determining the diversion of SF pins from assemblies. Preliminary results indicate that NRTA has great potential for being able to assay intact SF assemblies. Operating in the 1-40 eV range, it can identify four plutonium isotopes (239, 240, 241, & 242Pu), three uranium isotopes (235, 236, & 238U), and six resonant fission products (99Tc, 103Rh, 131Xe, 133Cs, 145Nd, and 152Sm). It can determine the areal density or mass of these isotopes in single- or multiple-pin integral transmission scans. Further, multiple observables exist to allow the detection of material diversion (pin defects) including fast-neutron and x-ray radiography, gross-transmission neutron counting, plutonium resonance absorption analysis, and fission-product resonance absorption analysis. Initial benchmark modeling has shown excellent agreement with previously published experimental data for measurements of individual SF pins where plutonium assays were experimentally demonstrated to have a precision of better than 3%.

Selection, follow-up, and analysis in the Atomic Bomb Casualty Commission Study  

SciTech Connect

More is known about ionizing radiation as a cause of human cancer than about any other carcinogen. Most of this knowledge is derived from the studies conducted by the Atomic Bomb Casualty Commission and Radiation Effects Research Foundation on about 100,000 Japanese survivors of the atomic bombing in 1945. The importance of these studies is based on the large size of the exposed population and the fact that individual estimates of radiation dose were possible. These factors and the combined excellence of the centralized vital statistics reporting and population registration systems in Japan have made feasible the continuing longitudinal studies of cancer mortality by site in relation to radiation dose over a span of more than 30 years. Excellent voluntary cooperation by the survivors has enabled the continuation of a biennial physical examination program which has made possible the acquisition of blood for studies of radiation-induced chromosomal aberrations and mutations at the level of specific genes. Similarly, with the cooperation of local universities, hospitals, and physicians, tumor and tissue registries necessary for the study of cancer incidence have been developed. An autopsy pathology program has enabled study of the accuracy of cause of death certification.

Natural Tracers and Multi-Scale Assessment of Caprock Sealing Behavior: A Case Study of the Kirtland Formation, San Juan Basin  

Science Conference Proceedings (OSTI)

The assessment of caprocks for geologic CO{sub 2} storage is a multi-scale endeavor. Investigation of a regional caprock - the Kirtland Formation, San Juan Basin, USA - at the pore-network scale indicates high capillary sealing capacity and low permeabilities. Core and wellscale data, however, indicate a potential seal bypass system as evidenced by multiple mineralized fractures and methane gas saturations within the caprock. Our interpretation of {sup 4}He concentrations, measured at the top and bottom of the caprock, suggests low fluid fluxes through the caprock: (1) Of the total {sup 4}He produced in situ (i.e., at the locations of sampling) by uranium and thorium decay since deposition of the Kirtland Formation, a large portion still resides in the pore fluids. (2) Simple advection-only and advection-diffusion models, using the measured {sup 4}He concentrations, indicate low permeability ({approx}10-20 m{sup 2} or lower) for the thickness of the Kirtland Formation. These findings, however, do not guarantee the lack of a large-scale bypass system. The measured data, located near the boundary conditions of the models (i.e., the overlying and underlying aquifers), limit our testing of conceptual models and the sensitivity of model parameterization. Thus, we suggest approaches for future studies to better assess the presence or lack of a seal bypass system at this particular site and for other sites in general.

Diagnosis of the Low-Level Jet using a sounding analysis scheme and the ETA model, a case study  

E-Print Network (OSTI)

The LLJ transports moisture northward from the Gulf of Mexico into the Great Plains. Proper detection of the LLJ is important in aviation and forecasting. Standard atmospheric charts are usually insufficient in properly depicting the structure and intensity of the LLJ. This limitation arises because the LLJ climbs in altitude as it flows northward. A sounding analysis scheme is presented as an alternative to currently existing LLJ detection methods. The intensity and aerial coverage of the LLJ were studied using this analysis scheme during a case study from May 1995. The data set used consisted of 80-km Eta model output. When compared to other methods, the developed analysis scheme showed more LLJ detail and structure. The LLJ appeared with multiple cores as opposed to one long and continuous core, as typically depicted at the 850-mb level. This fits in with current research that shows the existence of multiple LLJ cores caused by different factors, such as synoptic influences, orography, and a strong low-level pressure gradient. The method developed in this research is proposed as an alternate method for LLJ detection.

Preliminary Analysis and Case Study of Transmission Constraints and Wind Energy in the West: Preprint  

DOE Green Energy (OSTI)

Wind developers typically need long-term transmission service to finance their projects; however, most of the capacity on several key paths is reserved by existing firm contracts. Because non-firm contracts are only offered for periods up to 1 year, obtaining financing for the wind project is generally not possible when firm capacity is unavailable. However, sufficient capacity may exist on the constrained paths for new wind projects that can risk curtailment for a small number of hours of the year. This paper presents the results of a study sponsored by the National Renewable Energy Laboratory (NREL), a work group participant in the Rocky Mountain Area Transmission Study (RMATS). Using recent historical power flow data, case studies were conducted on the constrained paths between Wyoming-Colorado (TOT3) and Montana-Northwest, coinciding with areas of exceptional wind resources. The potential curtailment frequency for hypothetical 100-MW and 500-MW wind plants was calculated using hourly wind data. The results from the study indicate that sufficient potential exists for innovative transmission products that can help bring more wind to load centers and increase the efficiency of the existing transmission network.

Proteogenomic analysis of bacteria and archaea: A 46 organism case study  

Science Conference Proceedings (OSTI)

Experimental evidence is increasingly being used to reassess the quality and accuracy of genome annotation. Proteomics data used for this purpose, called proteogenomics, can alleviate many of the problematic areas of genome annotation, e.g. short protein validation and start site assignment. We performed a proteogenomic analysis of 51 genomes spanning eight bacterial and archaeal phyla across the tree of life. These diverse datasets facilitated the development of a robust approach for proteogenomics that is functional across genomes varying in %GC, gene content, proteomic sampling depth, phylogeny, and genome size. In addition to finding evidence for 701 novel proteins, 1365 new start sites, and numerous dubious genes, we discovered sites of post-translational maturation in the form of proteolytic cleavage of 1095 signal peptides. Proteomics provides a powerful experimental data type to access and improve the quality of genome annotation. A key advantage is the direct correlation between protein annotation and a protein based assay. With the adoption of new sequencing technologies which have higher error rates than Sanger-based methods and the advances in proteomics, proteogenomics may become even more important in the future.

Study of a Fault Analysis System for a Heat Supply Network Based on GIS  

E-Print Network (OSTI)

Conventional methods cannot satisfy the request of the layout and operation management in a heating system. The geographical information system (GIS) in a heat supply network can realize information conformity and information share roundly, which makes management of information improve to a new level in district heating. When fault of the heat supply network occurs, the traditional methods make fault reaction time long and the efficiency low, and enlarge the fault harm. The system of fault analysis in a heat supply network based on GIS mainly simulates and calculates according to various fault conditions. By selection of valve shut-off schemes in fault conditions and simulation of various fault conditions, the fault treatment scheme can be optimized. The results of simulation can be shown in the GIS graphics with the aid of advanced image display function of GIS. The application of this system brings great significance to heating system on the management enhancing, fault number-reducing, quick decision-making and influence area diminishing in case of fault.

Behavior of oil muds during drilling operations  

Science Conference Proceedings (OSTI)

This paper presents an analysis of the behavior of diesel-oil-based muds with an advanced thermal and hydraulic wellbore mathematical simulator. Recent diesel-oil-mud rheological correlations have been incorporated into the model to account for viscosity and density variations of oil mud with temperature and pressure. As rheological correlations are developed for other oil-based muds, such as mineral-oil based muds, they can also be incorporated into the model. A specific deep-well application of the model illustrates the behavior of the oil-based muds and shows the differences between water-based mud and oil-mud for local fluid densities during drilling, circulating, and static conditions. Temperature and density profiles are presented for various operating conditions to show that modeling improves the understanding of oil-mud behavior downhole.

Conceptual design and systems analysis of photovoltaic systems. Volume II. Study results. Final report  

DOE Green Energy (OSTI)

This investigation of terrestrial PV systems considered the technical and economic feasibility for systems in three size categories: a small system of about 12 kW peak output for on-site residential use; a large 1500 MW central power plant contributing to the bulk energy of a utility system power grid; and an intermediate size system of about 250 kW for use on public or commercial buildings. In each category, conceptual designs were developed, performance was analyzed for a range of climatic regions, economic analyses were performed, and assessments were made of pertinent institutional issues. The report consists of three volumes. Volume I contains a Study Summary of the major study results. This volume contains the detailed results pertaining to on-site residential photovoltaic systems, central power plant photovoltaic systems, and intermediate size systems applied to commercial and public buildings.

Analysis of energy use in building services of the industrial sector in California: Two case studies  

SciTech Connect

Energy-use patterns in many of California's fastest-growing industries are not typical of the existing mix of industries in the US. Many California firms operate small- and medium-sized facilities housed in buildings used simultaneously or interchangeably over time for commercial (office, retail, warehouse) and industrial activities. In these industrial subsectors, the energy required for building services (providing occupant comfort and necessities like lighting, HVAC, office equipment, computers, etc.) may be at least as important as the more familiar process energy requirements -- especially for electricity and on-peak demand. Electricity for building services is sometimes priced as if it were base loaded like process uses; in reality this load varies significantly according to occupancy schedules and cooling and heating loads, much as in any commercial building. Using informal field surveys, simulation studies, and detailed analyses of existing data (including utility commercial/industrial audit files), we studied the energy use of this industrial subsector through a multi-step procedure: (1) characterizing non-process building energy and power use in California industries, (2) identifying conservation and load-shaping opportunities in industrial building services, and (3) investigating industrial buildings and system design methodologies. In an earlier report, we addressed these issues by performing an extensive survey of the existing publicly available data, characterizing and comparing the building energy use in this sector. In this report, we address the above objectives by examining and analyzing energy use in two industrial case-study facilities in California. Based on the information for the case studies, we discuss the design consideration for these industrial buildings, characterize their energy use, and review their conservation and load-shaping potentials. In addition, we identify and discuss some research ideas for further investigation.

Application of thermogravimetric analysis to study the thermal degradation of solid and liquid organic wastes  

Science Conference Proceedings (OSTI)

In this work, the thermolysis of composite binary mixtures of refinery or coal-processing waste with waste biomass and D-grade (long-flame) coal was analyzed in order to increase the efficiency of the cothermolysis of chemically different organic wastes mainly because of the synergism of the thermolysis of mixture components and, correspondingly, the selectivity of formation of high-quality by-products (solid, gaseous, or liquid). A new approach to the analysis of thermogravimetric data was proposed and developed as applied to complex binary mixtures of carbon-containing materials. This approach was based on (1) the preliminary separation of the thermal degradation of individual carbon-containing mixture components into individual structural constituents and (2) the monitoring of the conversion of each particular structure fragment as a constituent of the mixtures in the course of the cothermolysis of the mixtures of starting components. Based on the approach developed, data on the main synergism effects in the course of cothermolysis in the binary test systems were obtained: the temperature regions of the appearance of these effects were distinguished, the main conclusions were made with respect to particular structure fragments in complex organic wastes responsible for the interaction of components in composite systems, and the directions (positive or negative) of changes in the yields of solid by-products and the degrees of effects (difference between the yields of cothermolysis by-products in each particular region of the appearance of synergistic effects in the systems) were determined. Additionally, the influence of alkali metal carbonate additives on synergistic effects in the interaction between binary system components under the process conditions of cothermolysis was analyzed.

Nuclear-fission studies with relativistic secondary beams: analysis of fission channels  

E-Print Network (OSTI)

Nuclear fission of several neutron-deficient actinides and pre-actinides from excitation energies around 11 MeV was studied at GSI Darmstadt by use of relativistic secondary beams. The characteristics of multimodal fission of nuclei around 226Th are systematically investigated and interpreted as the superposition of three fission channels. Properties of these fission channels have been determined for 15 systems. A global view on the properties of fission channels including previous results is presented. The positions of the asymmetric fission channels are found to be constant in element number over the whole range of systems investigated.

MRS (monitored retrievable storage) Systems Study Task 1 report: Waste management system reliability analysis  

Science Conference Proceedings (OSTI)

This is one of nine studies undertaken by contractors to the US Department of Energy (DOE), Office of Civilian Radioactive Waste Management (OCRWM), to provide a technical basis for re-evaluating the role of a monitored retrievable storage (MRS) facility. The study evaluates the relative reliabilities of systems with and without an MRS facility using current facility design bases. The principal finding of this report is that the MRS system has several operational advantages that enhance system reliability. These are: (1) the MRS system is likely to encounter fewer technical issues, (2) the MRS would assure adequate system surface storage capacity to accommodate repository construction and startup delays of up to five years or longer if the Nuclear Waste Policy Amendments Act (NWPAA) were amended, (3) the system with an MRS has two federal acceptance facilities with parallel transportation routing and surface storage capacity, and (4) the MRS system would allow continued waste acceptance for up to a year after a major disruption of emplacement operations at the repository.

Seismic hazard analysis application of methodology, results, and sensitivity studies. Volume 4  

Science Conference Proceedings (OSTI)

As part of the Site Specific Spectra Project, this report seeks to identify the sources of and minimize uncertainty in estimates of seismic hazards in the Eastern United States. Findings are being used by the Nuclear Regulatory Commission to develop a synthesis among various methods that can be used in evaluating seismic hazard at the various plants in the Eastern United States. In this volume, one of a five-volume series, we discuss the application of the probabilistic approach using expert opinion. The seismic hazard is developed at nine sites in the Central and Northeastern United States, and both individual experts' and synthesis results are obtained. We also discuss and evaluate the ground motion models used to develop the seismic hazard at the various sites, analyzing extensive sensitivity studies to determine the important parameters and the significance of uncertainty in them. Comparisons are made between probabilistic and real spectral for a number of Eastern earthquakes. The uncertainty in the real spectra is examined as a function of the key earthquake source parameters. In our opinion, the single most important conclusion of this study is that the use of expert opinion to supplement the sparse data available on Eastern United States earthquakes is a viable approach for determining estimted seismic hazard in this region of the country. 29 refs., 15 tabs.

Constitutive model effects on finite element modeling of elastomer behavior in radial interference seal configurations  

E-Print Network (OSTI)

Elastomers are becoming more prevalent in everyday products, and it is very important to be able to describe their behavior. Particularly, with advancements in computer hardware and software, the use of finite element analysis in design and analysis is becoming more prevalent. However, there is no accepted and agreed upon method to generally describe elastomer behavior in the finite element codes. Evaluation of two existing material models found in most FEA packages was conducted using experimental data gathered and fit to each model's strain energy function. The effects of using various combinations of material model and experimental data have been studied. The modeling started with simple stress states and progressed to some more general in nature. The two strain energy fimctions used were the Mooney-Rivlin and a 5 term expansion of the Rivlin series called the Polynomial (N=2) function.

Energy-water analysis of the 10-year WECC transmission planning study cases.  

DOE Green Energy (OSTI)

In 2011 the Department of Energy's Office of Electricity embarked on a comprehensive program to assist our Nation's three primary electric interconnections with long term transmission planning. Given the growing concern over water resources in the western U.S. the Western Electricity Coordinating Council (WECC) requested assistance with integrating water resource considerations into their broader electric transmission planning. The result is a project with three overarching objectives: (1) Develop an integrated Energy-Water Decision Support System (DSS) that will enable planners in the Western Interconnection to analyze the potential implications of water stress for transmission and resource planning. (2) Pursue the formulation and development of the Energy-Water DSS through a strongly collaborative process between the Western Electricity Coordinating Council (WECC), Western Governors Association (WGA), the Western States Water Council (WSWC) and their associated stakeholder teams. (3) Exercise the Energy-Water DSS to investigate water stress implications of the transmission planning scenarios put forward by WECC, WGA, and WSWC. The foundation for the Energy-Water DSS is Sandia National Laboratories Energy-Power-Water Simulation (EPWSim) model (Tidwell et al. 2009). The modeling framework targets the shared needs of energy and water producers, resource managers, regulators, and decision makers at the federal, state and local levels. This framework provides an interactive environment to explore trade-offs, and 'best' alternatives among a broad list of energy/water options and objectives. The decision support framework is formulated in a modular architecture, facilitating tailored analyses over different geographical regions and scales (e.g., state, county, watershed, interconnection). An interactive interface allows direct control of the model and access to real-time results displayed as charts, graphs and maps. The framework currently supports modules for calculating water withdrawal and consumption for current and planned electric power generation; projected water demand from competing use sectors; and, surface and groundwater availability. WECC's long range planning is organized according to two target planning horizons, a 10-year and a 20-year. This study supports WECC in the 10-year planning endeavor. In this case the water implications associated with four of WECC's alternative future study cases (described below) are calculated and reported. In future phases of planning we will work with WECC to craft study cases that aim to reduce the thermoelectric footprint of the interconnection and/or limit production in the most water stressed regions of the West.

Monte Carlo Study of the abBA Experiment: Detector Response and Physics Analysis  

E-Print Network (OSTI)

The abBA collaboration proposes to conduct a comprehensive program of precise measurements of neutron $\\beta$-decay coefficients $a$ (the correlation between the neutrino momentum and the decay electron momentum), $b$ (the electron energy spectral distortion term), $A$ (the correlation between the neutron spin and the decay electron momentum), and $B$ (the correlation between the neutron spin and the decay neutrino momentum) at a cold neutron beam facility. We have used a GEANT4-based code to simulate the propagation of decay electrons and protons in the electromagnetic spectrometer and study the energy and timing response of a pair of Silicon detectors. We used these results to examine systematic effects and find the uncertainties with which the physics parameters $a$, $b$, $A$, and $B$ can be extracted from an over-determined experimental data set.

Prefeasibility analysis and study of the seasonal storage systems for the Pennsylvania Avenue Redevelopment Project  

DOE Green Energy (OSTI)

An Annual Cycle Energy Storage (ACES) concept as applied on a community scale to Market Square Complex on Pennsylvania Avenue, Washington, D.C. is discussed. Four alternatives of seasonal energy storage are examined. Each alternative was examined on the energy saving aspect and its operational and economic feasibility. Of the alternatives considered the most efficient system from the point of view of energy and economic feasibility was found to be system No. 3 dealing with heat pump generated ice for seasonal storage and it was thus selected and recommended for further study. The system utilizes the heat pump for heating the buildings in winter and for meeting the domestic hot water requirements. The heat pump obtains its heat by extracting the heat of fusion of water and thereby converting it to ice. The method suggested is to use the ice maker evaporator with water sprayed over the evaporator coil and being converted to ice. The ice would be used to cool the buildings during the summer by circulating chilled water through the ice bin. This system is expected to supply about 70% of the summer cooling requirements and provide a 100% cut in electric peak demand. The heat pumpsystem using the slab as storage of the heat rejected for reusing in winter time was found inefficient from the energy point of view. Only about 4% of the heat required during winter could be stored in the slab. The solar energy annual storage was found efficient energywise but prohibitive from the economical point of view. The winter cold air potential to make ice for storage was found efficient from the energy point of view but prohibitive from the economical point of view and because of unpredictability of system performance. It is therefore, recommended that the heat pump system with ice storage be taken up for a further feasibility study.

Phase behavior of DODAB aqueous solution  

SciTech Connect

Phase behavior of DODAB aqueous solution, prepared without sonication, was studied by adiabatic scanning calorimetry. Measurements revealed four phase transitions with the temperatures 35.2, 39.6, 44.6, and 52.4 Degree-Sign C at heating and one transition at the temperature 40.4 Degree-Sign C at cooling. The first three transitions at heating occur in unilamellar vesicles. The first and third transitions correspond to the subgel-gel and gelliquid phase transitions, corresponding enthalpy jumps are equal to 33 and 49 kJ/mol. The second transition appears after some aging and is similar to gel-ripple phase transition in a DPPC solution, with the enthalpy jump under the transition exceeding 7.4 kJ/mol. The transition occurs in unilamellar vesicles. The transition at the temperature 52.4 Degree-Sign C occurs in another subsystem of the solution, which we believe to be multilamellar vesicles. The enthalpy jump at this transition is equal to 97 kJ/mol, and data analysis suggests that this is a subgel-liquid transition. The phase transition at cooling is the liquid-gel transition in unilamellar vesicles. During the measurements, a slow evolution of the solution occurs, consisting in a change of concentrations of unilamellar and multilamellar vesicles. This transformation mainly occurs at low temperatures.

Mathematical modeling of the behavior of geothermal systems under exploitation  

DOE Green Energy (OSTI)

Analytical and numerical methods have been used in this investigation to model the behavior of geothermal systems under exploitation. The work is divided into three parts: (1) development of a numerical code, (2) theoretical studies of geothermal systems, and (3) field applications. A new single-phase three-dimensional simulator, capable of solving heat and mass flow problems in a saturated, heterogeneous porous or fractured medium has been developed. The simulator uses the integrated finite difference method for formulating the governing equations and an efficient sparse solver for the solution of the linearized equations. In the theoretical studies, various reservoir engineering problems have been examined. These include (a) well-test analysis, (b) exploitation strategies, (c) injection into fractured rocks, and (d) fault-charged geothermal reservoirs.

Comprehensive Mechanisms for Combustion Chemistry: An Experimental and Numerical Study with Emphasis on Applied Sensitivity Analysis  

Science Conference Proceedings (OSTI)

This project was an integrated experimental/numerical effort to study pyrolysis and oxidation reactions and mechanisms for small-molecule hydrocarbon structures under conditions representative of combustion environments. The experimental aspects of the work were conducted in large-diameter flow reactors, at 0.3 to 18 atm pressure, 500 to 1100 K temperature, and 10-2 to 2 seconds reaction time. Experiments were also conducted to determine reference laminar flame speeds using a premixed laminar stagnation flame experiment and particle image velocimetry, as well as pressurized bomb experiments. Flow reactor data for oxidation experiments include: (1)adiabatic/isothermal species time-histories of a reaction under fixed initial pressure, temperature, and composition; to determine the species present after a fixed reaction time, initial pressure; (2)species distributions with varying initial reaction temperature; (3)perturbations of a well-defined reaction systems (e.g. CO/H2/O2 or H2/O2)by the addition of small amounts of an additive species. Radical scavenging techniques are applied to determine unimolecular decomposition rates from pyrolysis experiments. Laminar flame speed measurements are determined as a function of equivalence ratio, dilution, and unburned gas temperature at 1 atm pressure. Hierarchical, comprehensive mechanistic construction methods were applied to develop detailed kinetic mechanisms which describe the measurements and literature kinetic data. Modeling using well-defined and validated mechanisms for the CO/H2/Oxidant systems and perturbations of oxidation experiments by small amounts of additives were also used to derive absolute reaction rates and to investigate the compatibility of published elementary kinetic and thermochemical information. Numerical tools were developed and applied to assess the importance of individual elementary reactions to the predictive performance of the developed mechanisms and to assess the uncertainties in elementary rate constant evaluations.

Study and analysis of the stress state in a ceramic, button-head, tensile specimen  

DOE Green Energy (OSTI)

The final results are reported for a study to identify and correct the causes of nongage-section failures (notably button-head failures) in ceramic tensile specimens observed in several laboratories. Numerical modeling of several candidate specimen gripping systems has shown inherent stress concentrations near the specimen button head at which the maximum stress may approach 75 to 100% of the gage-section stress for certain grip conditions. Empirical comparisons of both tapered- and straight-collet gripping systems revealed compromises in both systems. The straight-collet system, with deformable collets, is simpler to use but produces statistically significant greater average percent bending for all tests than those produced for the tapered-collet system, which is slightly more difficult to use. Empirical tensile tests of {approximately}50 aluminium oxide and {approximately}50 silicon nitride specimens were conducted to evaluate the loading capability of both gripping systems, the percent bending in each system, and the potential of consistently producing successful test results. These tests revealed that, due to variations in individuals specimens or the individual specimen/grip interfaces, neither of the gripping systems can consistently produce bending of less than 3 to 4% at failure although occasional values of {approximately}0.5% bending were attained. Refinements of grinding procedures and dimensional measurement techniques have shown critical details in both the practices and consistency of machining necessary for achieving the dimensional tolerances while minimizing subsurface damage. Numerical integration techniques indicate that up to a consistent 5.0% bending during fast- fracture tests can be tolerated before large influences are detected in the determination of the Weibull modulus and the Weibull characteristic strength.

Distributed energy resources in practice: A case study analysis and validation of LBNL's customer adoption model  

SciTech Connect

This report describes a Berkeley Lab effort to model the economics and operation of small-scale (<500 kW) on-site electricity generators based on real-world installations at several example customer sites. This work builds upon the previous development of the Distributed Energy Resource Customer Adoption Model (DER-CAM), a tool designed to find the optimal combination of installed equipment, and idealized operating schedule, that would minimize the site's energy bills, given performance and cost data on available DER technologies, utility tariffs, and site electrical and thermal loads over a historic test period, usually a recent year. This study offered the first opportunity to apply DER-CAM in a real-world setting and evaluate its modeling results. DER-CAM has three possible applications: first, it can be used to guide choices of equipment at specific sites, or provide general solutions for example sites and propose good choices for sites with similar circumstances; second, it can additionally provide the basis for the operations of installed on-site generation; and third, it can be used to assess the market potential of technologies by anticipating which kinds of customers might find various technologies attractive. A list of approximately 90 DER candidate sites was compiled and each site's DER characteristics and their willingness to volunteer information was assessed, producing detailed information on about 15 sites of which five sites were analyzed in depth. The five sites were not intended to provide a random sample, rather they were chosen to provide some diversity of business activity, geography, and technology. More importantly, they were chosen in the hope of finding examples of true business decisions made based on somewhat sophisticated analyses, and pilot or demonstration projects were avoided. Information on the benefits and pitfalls of implementing a DER system was also presented from an additional ten sites including agriculture, education, health care, airport, and manufacturing facilities.

Installation of cogeneration system based on Gas Turbine (GT) and Heat Recovery Heat Exchanger with thermal capacity of 30 MW and electrical capacity of 13.5 MW. This Option assumes utilization of five existing boilers with total capacity of 221 MW. Existing boilers will be equipped with modern controls. Equipment in this Option was sized for longest operating hours, about 8000 based on the available summer baseload. 2. Installation of Gas Turbine Combined Cycle (GTCC) and Heat Recovery Steam Generator (HRSG) with thermal capacity 45 MW and electrical capacity of 58.7 MW. This Option assumes utilization of five existing boilers with total capacity of 221 MW. Existing boilers will be equipped with modern controls. The equipment was sized for medium, shoulder season thermal load, and some cooling was assumed during the summer operation for extension of operating hours for electricity production. 3. Retrofit of six existing boilers (NGB) with total thermal capacity of 255.9 MW by installation of modern control system and minor upgrades. This option assumes only heat production with minimum investment. The best economic performance and the largest investment cost would result from alternative GTCC. This alternative has positive Net Present Value (NPV) with discount rate lower than about 12%, and has IRR slightly above 12%. The lowest economic results, and the lowest required investment, would result from alternative NGB. This Option's NPV is negative even at 0% discount rate, and would not become positive even by improving some parameters within a reasonable range. The Option with Gas Turbine displays relatively modest results and the NPV is positive for low discount rate, higher price of sold electricity and lower cost of natural gas. The IRR of this alternative is 9.75%, which is not very attractive. The largest influences on the investment are from the cost of electricity sold to the grid, the heat tariff, and the cost of natural gas. Assuming the implementation of the GTCC alternative, the benefit of the project is also reflected in lower Green House Emissions.

The Behavior of Lakes  

NLE Websites -- All DOE Office Websites (Extended Search)

Behavior of Lakes Behavior of Lakes Nature Bulletin No, 320-A November 9, 1968 Forest Preserve District of Cook County Richard B. Ogilvie, President Roland F. Eisenbeis, Supt. of Conservation THE BEHAVIOR OF LAKES In many ways lakes are like living things -- especially a tree. A lake breathes and has a circulation; it is warmed and fed; it harbors many other living things; and in cold weather it goes into a winter sleep. If it were not for the special character of a body of standing water which we call a lake, the things that live in it would be radically different or, perhaps, not exist at all. Water is a very strange substance in many ways. For example, it is remarkable because it expands, becomes lighter and floats when it freezes into ice. If, like most substances, water shrank when it changed from a liquid to a solid, it would sink. Then, ponds and lakes would freeze from the bottom up and become solid blocks of ice. This would make life impossible for most kinds of aquatic plants and animals and indirectly affect all living things. Further, water is a poor conductor of heat -- otherwise lakes would freeze much deeper and, again most living things in it would perish.

Individual energy-conservation behaviors  

SciTech Connect

One important basis for sound energy policy is an understanding of how American consumers view and practice energy conservation. Project Monitor, a study of consumers' energy attitudes and behavior surveyed more than 1000 household consumers to determine individual attributes, situational factors, attitudes, and perceptions that influence (or fail to influence) energy conservation. Using these data, the authors related specific types of energy conservation - general, winterization, heating, cooling, appliance, transportation, and electricity reductions - to 24 demographic, situational, attitudinal, and perceptual variables in the household sample. To determine the characteristics that differentiate conservers from nonconservers, simple correlations are made between each of the independent variables and the dependent measures of conservation; the results of multivariate regression analyses are used to estimate the effects of the independent variables simultaneously. Also measured were the effects on households of two exogenous events during the period of the study. It concludes with recommendations for implementing and increasing energy conservation. 296 references, 42 tables.

Oil dependence and Thai foreign-policy behavior during the Arab-Israeli war of October 1973  

SciTech Connect

The purpose of this study is to explain Thai foreign-policy behavior toward the Arab-Israeli conflict during the Arab oil embargo of 1973-1974 in the wake of the October 1973 War. The major hypothesis is that Thai foreign policy behavior shifted from a neutral to a pro-Arab position after the Arab oil embargo. This shift was motivated by Thai oil-import dependence on OAPEC (Organization of Arab Petroleum Exporting Countries). Oil has assumed an economic as well as a political dimension. Therefore, its political influence over the oil-dependent states cannot be dismissed. Thai foreign-policy behavior in the Arab-Israeli conflict is analyzed through the use of the dependence approach, which contends that external reliance is a potent factor for explaining behavior of actors. Thailand's foreign-policy stand is first delineated through the use of documents containing policy statements by Thai delegates to the United Nations. It was found that although Thai public policy statements were never bluntly anti-Israel, they moved from between neutrality before the oil crisis to a pro-Arab position after the oil crisis of 1973-1974. This shift of Thailand's foreign policy behavior position was then measured against its UN voting records. Results of the voting analysis indicated that the shifting of Thai foreign policy behavior during the October war was motivated by Thailand's oil-import dependence.

Evaluation of uncertainties due to hydrogeological modeling and groundwater flow analysis: Steady flow, transient flow, and thermal studies  

SciTech Connect

Starting with regional geographic, geologic, surface and subsurface hydrologic, and geophysical data for the Tono area in Gifu, Japan, we develop an effective continuum model to simulate subsurface flow and transport in a 4 km by 6 km by 3 km thick fractured granite rock mass overlain by sedimentary layers. Individual fractures are not modeled explicitly. Rather, continuum permeability and porosity distributions are assigned stochastically, based on well-test data and fracture density measurements. Lithologic layering and one major fault, the Tsukiyoshi Fault, are assigned deterministically. We conduct three different studies: (1) the so-called base case, in which the model simulates the steady-state groundwater flow through the site, and then stream trace analysis is used to calculate travel times to the model boundary from specified release points; (2) simulations of transient flow during long term pump tests (LTPT) using the base-case model; and (3) thermal studies in which coupled heat flow and fluid flow are modeled, to examine the effects of the geothermal gradient on groundwater flow. The base-case study indicates that the choice of open or closed lateral boundaries has a strong influence on the regional groundwater flow patterns produced by the models, but no field data exist that can be used to determine which boundary conditions are more realistic. The LTPT study cannot be used to distinguish between the alternative boundary conditions, because the pumping rate is too small to produce an analyzable pressure response at the model boundaries. In contrast, the thermal study shows that the temperature distributions produced by the open and closed models differ greatly. Comparison with borehole temperature data may be used to eliminate the closed model from further consideration.

Thermogravimetric analysis studies  

SciTech Connect

Independent of thermal loading scenarios, the waste packages at the proposed repository at Yucca Mountain, Nevada will be exposed to environmental conditions of temperatures below 100 C with a range of possible relative humidities. Under high relative humidities, the formation of thin water films on the metal surfaces will occur. Previous work at ambient conditions has shown that on susceptible metals, the water-film-covered metal has an enhanced corrosion rate relative to the dry oxidation of the metal. The transition relative humidity where oxidation changes from dry oxidation to aqueous electrochemical corrosion is called the critical relative humidity. Determination of this transition is important in estimating the performance of the candidate materials (especially corrosion allowance materials), because of the marked increase in degradation rate above the critical relative humidity, typically 10-10{sup 2} times This activity is concerned with short term measurements of corrosion and oxidation rates using a high sensitivity microbalance. The experimental work will determine the critical humidity level for candidate metals under a variety of conditions. From the literature, the critical humidity level typically are around 70% relative humidity, but this level is affected by the metal, gas composition, temperature, and the presence of contaminants on the surface, particularly contaminants that are deliquescent. A series of experiments will bracket a range of humidity, temperature, metal alloy, and surface condition.

A retrospective study of the chemical analysis cost for the remediation of Lower East Fork Poplar Creek, Oak Ridge, Tennessee  

Science Conference Proceedings (OSTI)

A retrospective study of the remediation of Lower East Fork Poplar Creek (LEFPC) in Oak Ridge, Tennessee was completed. The study was conducted by reviewing the public Comprehensive Environmental Response, Compensation, and Liability Act record documents associated with the remediation of LEFPC and through discussions with the project staff involved or familiar with the project. The remediation took place in two phases. The first phase involved the excavation of about 5,560 yd{sup 3} of soil at the National Oceanic and Atmospheric Administration (NOAA) locations in 1996. The second phase involved the excavation of 39,200 yd{sup 3} at another NOAA location and at the Bruner location in 1997. For the entire project (remedial investigation through cleanup), a total of 7,708 samples (1 sample for each 5.8 yd{sup 3} of soil remediated) were analyzed for mercury. The project obtained special regulatory approval to use two methods for the determination of mercury in soils that are not part of the Resource Conservation and Recovery Act SW-846 methods manual. The mercury analysis cost was $678,000, which represents 9.6% of the cleanup cost. During the cleanup phase of the project, an on-site laboratory was used. The estimated cost savings that the on-site laboratory provided fall into two categories: direct reduction of costs associated with chemical analysis and sample shipment totaling approximately $38,000, which represents a 5.3% savings relative to the estimated cost of using an off-site laboratory, and savings in the amount of $890,000 (12.5% of the $7.1 M cleanup cost), associated with expediting execution of the cleanup work by providing rapid (< 3 hours) sample result turnaround time. The manner in which the analytical services were procured for the LEFPC project suggest that the development of new chemical analysis technology must address deployment, performance, regulatory, robustness, reliability, and business appropriateness factors if the technology is to be used in environmental remediation.

Calibrating Bayesian Network Representations of Social-Behavioral Models  

Science Conference Proceedings (OSTI)

While human behavior has long been studied, recent and ongoing advances in computational modeling present opportunities for recasting research outcomes in human behavior. In this paper we describe how Bayesian networks can represent outcomes of human behavior research. We demonstrate a Bayesian network that represents political radicalization research – and show a corresponding visual representation of aspects of this research outcome. Since Bayesian networks can be quantitatively compared with external observations, the representation can also be used for empirical assessments of the research which the network summarizes. For a political radicalization model based on published research, we show this empirical comparison with data taken from the Minorities at Risk Organizational Behaviors database.

Multi-wavelength analysis of high energy electrons in solar flares: a case study of August 20, 2002 flare  

E-Print Network (OSTI)

A multi-wavelength spatial and temporal analysis of solar high energy electrons is conducted using the August 20, 2002 flare of an unusually flat (gamma=1.8) hard X-ray spectrum. The flare is studied using RHESSI, Halpha, radio, TRACE, and MDI observations with advanced methods and techniques never previously applied in the solar flare context. A new method to account for X-ray Compton backscattering in the photosphere (photospheric albedo) has been used to deduce the primary X-ray flare spectra. The mean electron flux distribution has been analysed using both forward fitting and model independent inversion methods of spectral analysis. We show that the contribution of the photospheric albedo to the photon spectrum modifies the calculated mean electron flux distribution, mainly at energies below 100 keV. The positions of the Halpha emission and hard X-ray sources with respect to the current-free extrapolation of the MDI photospheric magnetic field and the characteristics of the radio emission provide evidence of the closed geometry of the magnetic field structure and the flare process in low altitude magnetic loops. In agreement with the predictions of some solar flare models, the hard X-ray sources are located on the external edges of the Halpha emission and show chromospheric plasma heated by the non-thermal electrons. The fast changes of Halpha intensities are located not only inside the hard X-ray sources, as expected if they are the signatures of the chromospheric response to the electron bombardment, but also away from them.

Function-based Design Tools for Analyzing the Behavior and Sensitivity of Complex Systems During Conceptual Design  

E-Print Network (OSTI)

Complex engineering systems involve large numbers of functional elements. Each functional element can exhibit complex behavior itself. Ensuring the ability of such systems to meet the customer's needs and requirements requires modeling the behavior of these systems. Behavioral modeling allows a quantitative assessment of the ability of a system to meet specific requirements. However, modeling the behavior of complex systems is difficult due to the complexity of the elements involved and more importantly the complexity of these elements' interactions. In prior work, formal functional modeling techniques have been applied as a means of performing a qualitative decomposition of systems to ensure that needs and requirements are addressed by the functional elements of the system. Extending this functional decomposition to a quantitative representation of the behavior of a system represents a significant opportunity to improve the design process of complex systems. To this end, a functionality-based behavioral modeling framework is proposed along with a sensitivity analysis method to support the design process of complex systems. These design tools have been implemented in a computational framework and have been used to model the behavior of various engineering systems to demonstrate their maturity, application and effectiveness. The most significant result is a multi-fidelity model of a hybrid internal combustion-electric racecar powertrain that enabled a comprehensive quantitative study of longitudinal vehicle performance during various stages in the design process. This model was developed using the functionality-based framework and allowed a thorough exploration of the design space at various levels of fidelity. The functionality-based sensitivity analysis implemented along with the behavioral modeling approach provides measures similar to a variance-based approach with a computation burden of a local approach. The use of a functional decomposition in both the behavioral modeling and sensitivity analysis significantly contributes to the flexibility of the models and their application in current and future design efforts. This contribution was demonstrated in the application of the model to the 2009 Texas A&M Formula Hybrid powertrain design.

Development of SRC-I product analysis. Volume 2. Evaluation of analytical techniques for SRC-I characterization, recycle solvent studies, and product fractionation studies  

Science Conference Proceedings (OSTI)

A data analysis was performed to determine the relationship between the Wilsonville Solvent Quality test result and SRC liquefaction process parameters. The data base studied covers the years 1979 to 1982, Wilsonville runs 133 to 234. Only process-defined material balance data sets were included to best represent steady-state operation. Each material balance period provided 48 variables from which common process conditions were selected by imposing a range of acceptable deviations from a norm, e.g., a reactor hydrogen pressure of 2000 +- 100 psi. Data for all variables vs. solvent quality were plotted, and in some cases variables were compared with each other to determine common trends, e.g. gas production vs. hydrogen consumption. The plotted data produced no discernible trends. Separating the data by coal type (mine location) and identifying common process conditions with coal types still provided no absolute correlations with solvent quality. However, the effect of the weight percent pyrite present in the feed coal produced a consistent trend. A coal containing more than 1.2% pyrite and less than 0.1% sulfate sulfur yielded results in which any one correlation would cluster about a central point. It was observed that, on average, Kentucky Fies and Pyro mine coal and Indiana V coal clustered together, while Kentucky Lafayette and Dotiki mine coals clustered together. These data point clusters for the variables tested were nearly independent of reactor pressure, space rate, and temperature. One unusual observation of all the data points, independent of process conditions, was that at each change of feed coal, the sum of hydrocarbon and heteroatom gas production was greatest for the first 30 days, after which gas production reached a steady state dependent on process conditions, primarily temperature.

Solution behavior of PEO : the ultimate biocompatible polymer.  

DOE Green Energy (OSTI)

Poly(ethylene oxide) (PEO) is the quintessential biocompatible polymer. Due to its ability to form hydrogen bonds, it is soluble in water, and yet is uncharged and relatively inert. It is being investigated for use in a wide range of biomedical and biotechnical applications, including the prevention of protein adhesion (biofouling), controlled drug delivery, and tissue scaffolds. PEO has also been proposed for use in novel polymer hydrogel nanocomposites with superior mechanical properties. However, the phase behavior of PEO in water is highly anomalous and is not addressed by current theories of polymer solutions. The effective interactions between PEO and water are very concentration dependent, unlike other polymer/solvent systems, due to water-water and water-PEO hydrogen bonds. An understanding of this anomalous behavior requires a careful examination of PEO liquids and solutions on the molecular level. We performed massively parallel molecular dynamics simulations and self-consistent Polymer Reference Interaction Site Model (PRISM) calculations on PEO liquids. We also initiated MD studies on PEO/water solutions with and without an applied electric field. This work is summarized in three parts devoted to: (1) A comparison of MD simulations, theory and experiment on PEO liquids; (2) The implementation of water potentials into the LAMMPS MD code; and (3) A theoretical analysis of the effect of an applied electric field on the phase diagram of polymer solutions.

Characterizing Application Runtime Behavior from System Logs and Metrics  

Science Conference Proceedings (OSTI)

Large-scale systems are heavily shared resource environments where a mix of applications are launched concurrently competing for network and storage resources. It is essential to characterize the runtime behavior of these applications for provisioning system resources and understanding the impact of application s performance when competing for resources. In this paper, we study the use of zero- and low-overhead system logs and other system metric data for characterizing the runtime behavior of several applications. We present our preliminary work on estimating individual application s I/O demands by observing file system usage pattern over multiple runs, and interpreting application s network utilization characteristics by observing link-layer error logs. We also present preliminary findings on using such information in making context-sensitive scheduling decisions that minimize potentially negative interactions between applications competing for shared resources. Our analysis is based on four months of system log data collected on one of the world s largest supercomputing facilities, the Jaguar XT5 petaflop system at Oak Ridge National Laboratory.

Analysis of Unit-Level Changes in Operations with Increased SPP Wind from EPRI/LCG Balancing Study  

DOE Green Energy (OSTI)

Wind power development in the United States is outpacing previous estimates for many regions, particularly those with good wind resources. The pace of wind power deployment may soon outstrip regional capabilities to provide transmission and integration services to achieve the most economic power system operation. Conversely, regions such as the Southeastern United States do not have good wind resources and will have difficulty meeting proposed federal Renewable Portfolio Standards with local supply. There is a growing need to explore innovative solutions for collaborating between regions to achieve the least cost solution for meeting such a renewable energy mandate. The Department of Energy funded the project 'Integrating Midwest Wind Energy into Southeast Electricity Markets' to be led by EPRI in coordination with the main authorities for the regions: SPP, Entergy, TVA, Southern Company and OPC. EPRI utilized several subcontractors for the project including LCG, the developers of the model UPLAN. The study aims to evaluate the operating cost benefits of coordination of scheduling and balancing for Southwest Power Pool (SPP) wind transfers to Southeastern Electric Reliability Council (SERC) Balancing Authorities (BAs). The primary objective of this project is to analyze the benefits of regional cooperation for integrating mid-western wind energy into southeast electricity markets. Scenarios were defined, modeled and investigated to address production variability and uncertainty and the associated balancing of large quantities of wind power in SPP and delivery to energy markets in the southern regions of the SERC. DOE funded Oak Ridge National Laboratory to provide additional support to the project, including a review of results and any side analysis that may provide additional insight. This report is a unit-by-unit analysis of changes in operations due to the different scenarios used in the overall study. It focuses on the change in capacity factors and the number of start-ups required for each unit since those criteria summarize key aspects of plant operations, how often are they called upon and how much do they operate. The primary analysis of the overall project is based on security-constrained unit commitment (SCUC) and economic dispatch (SCED) simulations of the SPP-SERC regions as modeled for the year 2022. The SCUC/SCED models utilized for the project were developed through extensive consultation with the project utility partners, to ensure the various regions and operational practices are represented as best as possible in the model. SPP, Entergy, Oglethorpe Power Company (OPC), Southern Company, and the Tennessee Valley Authority (TVA) actively participated in the project providing input data for the models and review of simulation results and conclusions. While other SERC utility systems are modeled, the listed SERC utilities were explicitly included as active participants in the project due to the size of their load and relative proximity to SPP for importing wind energy.

DRAFT DO NOT QUOTE Energy Prices and Energy Intensity in China: A Structural Decomposition Analysis and Econometrics Study  

E-Print Network (OSTI)

Since the start of its economic reforms in 1978, China's energy prices relative to other prices have increased. At the same time, its energy intensity, i.e., energy consumption per unit of Gross Domestic Product (GDP), has declined dramatically, by about 70%, in spite of increases in energy consumption. Is this just a coincidence? Or does a systematic relationship exist between energy prices and energy intensity? In this study, we examine whether and how China’s energy price changes affect its energy intensity trend during 1980-2002 at a macro level. We conduct the research by using two complementary economic models: the input-output-based structural decomposition analysis (SDA) and econometric regression models and by using a decomposition method of own-price elasticity of energy intensity. Findings include a negative own-price elasticity of energy intensity, a price-inducement effect on energyefficiency improvement, and a greater sensitivity (in terms of the reaction of energy intensity towards changes in energy prices) of the industry sector, compared to the overall economy. Analysts can use these results as a starting point for China's energy and carbon

DOE Green Energy (OSTI)

This report describes the work performed by the University of Illinois at Urbana-Champaign. The following results were obtained under the work funded by this subcontract: (1) Point defects and electronic properties of Cu(In{sub 1-x}Ga{sub x})Se{sub 2}: New record results for hole mobilities in Cu(In{sub 1-x}Ga{sub x})Se{sub 2} based on single crystals grown by Rockett's group; Demonstrated the role of Ga in determining hole concentrations; Showed that Ga does not affect the hole mobility in this material and why this is the case; Determined the diffusion coefficient for Ga in single-crystal Cu(In{sub 1-x}Ga{sub x})Se{sub 2}; Demonstrated the structure and optoelectronic properties of the CuIn{sub 3}Se{sub 5} ordered-defect phase of CuInSe{sub 2}; Characterized the detailed effects of Na on Cu(In{sub 1-x}Ga{sub x})Se{sub 2} solar cells and on the fundamental properties of the material itself (reduces compensating donors in p-type materials); and In collaboration with groups at the Universities of Salford and Liverpool in the United Kingdom, studied the effect of ion implantation damage on Cu(In{sub 1-x}Ga{sub x})Se{sub 2} single-crystals. (2) Materials for and characterization of devices: Developed a novel contact metallurgy that improves adhesion to the underlying Mo back-contact in solar cells made with Cu(In{sub 1-x}Ga{sub x})Se{sub 2}; (This material has also yielded substantial novel materials science behaviors, including grain rotation and growth prior to phase separation in a metastable binary alloy.) Characterized the electroluminescence as a function of temperature and Ga content in Cu(In{sub 1-x}Ga{sub x})Se{sub 2} solar cells and showed that the radiative recombination pathways are not band-to-band as in normal semiconductors, but rather, proceed through defect states; and Working with a group at the University of Uppsala in Sweden, demonstrated novel aspects of the bonding and chemistry of dip-coated CdS heterojunction materials used as heterojunction partner materials in Cu(In{sub 1-x}Ga{sub x})Se{sub 2} solar cells.

Tracing the behavior of parallel applications on extreme-scale systems |  

NLE Websites -- All DOE Office Websites (Extended Search)

Tracing the behavior of parallel applications on extreme-scale systems Tracing the behavior of parallel applications on extreme-scale systems January 3, 2014 Tweet EmailPrint Event-tracing tools have proved vital for understanding how parallel applications behave. But new challenges make the use of event tracing on extreme-scale machines problematic. Tracing tools generate large amounts of data, which can overload the parallel file system and skew the application being studied. To remedy this problem, researchers from Argonne National Laboratory, the Technische Universität Dresden in Germany, and Oak Ridge National Laboratory have devised a new technique that enables event tracing on exascale systems. Scientists who have been using existing performance analysis tools find that these frequently do not scale to large systems. And even if they do

Strange Metallic Behavior in Anisotropic Background  

E-Print Network (OSTI)

We continue our analysis on conductivity in the anisotropic background by employing the D-brane probe technique, where the D-branes play the role of charge carriers. The DC and AC conductivity for massless charge carriers are obtained analytically, while interesting curves for the AC conductivity are also plotted. For massive charge carriers, we calculate the DC and AC conductivities in the dilute limit and we fix the parameters in the Einstein-Maxwell-dilaton theory so that the background exhibits the same scaling behaviors as those for real-world strange metals. The DC conductivity at finite density is also computed.

X-rays structural analysis and thermal stability studies of the ternary compound {alpha}-AlFeSi  

Science Conference Proceedings (OSTI)

From literature data presently available, the decomposition temperature and the nature of the decomposition reaction of the ternary compound {alpha}-AlFeSi (also designated as {alpha}{sub H} or {tau}{sub 5}) are not clearly identified. Moreover, some uncertainties remain concerning its crystal structure. The crystallographic structure and thermochemical behaviour of the ternary compound {alpha}-AlFeSi were meticulously studied. The crystal structure of {alpha}-AlFeSi was examined at room temperature from X-ray single crystal intensity data. It presents hexagonal symmetry, space group P6{sub 3}/mmc with unit cell parameters (293 K) a=12.345(2) A and c=26.210(3) A (V=3459 A{sup 3}). The average chemical formula obtained from refinement is Al{sub 7.1}Fe{sub 2}Si. From isothermal reaction-diffusion experiments and Differential Thermal Analysis, the title compound decomposes peritectically upon heating into {theta}-Fe{sub 4}Al{sub 13}(Si), {gamma}-Al{sub 3}FeSi and a ternary Al-rich liquid. Under atmospheric pressure, the temperature of this reversible transformation has been determined to be 772{+-}12 {sup o}C. -- Graphical abstract: Partial representation of the crystal structure of the {alpha}-Al{sub 7.1}Fe{sub 2}Si compound.

Use of 2nd and 3rd Level Correlation Analysis for Studying Degradation in Polycrystalline Thin-Film Solar Cells  

DOE Green Energy (OSTI)

The correlation of stress-induced changes in the performance of laboratory-made CdTe solar cells with various 2nd and 3rd level metrics is discussed. The overall behavior of aggregated data showing how cell efficiency changes as a function of open-circuit voltage (Voc), short-circuit current density (Jsc), and fill factor (FF) is explained using a two-diode, PSpice model in which degradation is simulated by systematically changing model parameters. FF shows the highest correlation with performance during stress, and is subsequently shown to be most affected by shunt resistance, recombination and in some cases voltage-dependent collection. Large decreases in Jsc as well as increasing rates of Voc degradation are related to voltage-dependent collection effects and catastrophic shunting respectively. Large decreases in Voc in the absence of catastrophic shunting are attributed to increased recombination. The relevance of capacitance-derived data correlated with both Voc and FF is discussed.

An analysis of the pull strength behaviors of fine-pitch, flip chip solder interconnections using a Au-Pt-Pd thick film conductor on Low-Temperature, Co-fired Ceramic (LTCC) substrates.  

Science Conference Proceedings (OSTI)

The assembly of the BDYE detector requires the attachment of sixteen silicon (Si) processor dice (eight on the top side; eight on the bottom side) onto a low-temperature, co-fired ceramic (LTCC) substrate using 63Sn-37Pb (wt.%, Sn-Pb) in a double-reflow soldering process (nitrogen). There are 132 solder joints per die. The bond pads were gold-platinum-palladium (71Au-26Pt-3Pd, wt.%) thick film layers fired onto the LTCC in a post-process sequence. The pull strength and failure modes provided the quality metrics for the Sn-Pb solder joints. Pull strengths were measured in both the as-fabricated condition and after exposure to thermal cycling (-55/125 C; 15 min hold times; 20 cycles). Extremely low pull strengths--referred to as the low pull strength phenomenon--were observed intermittently throughout the product build, resulting in added program costs, schedule delays, and a long-term reliability concern for the detector. There was no statistically significant correlation between the low pull strength phenomenon and (1) the LTCC 'sub-floor' lot; (2) grit blasting the LTCC surfaces prior to the post-process steps; (3) the post-process parameters; (4) the conductor pad height (thickness); (5) the dice soldering assembly sequence; or (5) the dice pull test sequence. Formation of an intermetallic compound (IMC)/LTCC interface caused by thick film consumption during either the soldering process or by solid-state IMC formation was not directly responsible for the low-strength phenomenon. Metallographic cross sections of solder joints from dice that exhibited the low pull strength behavior, revealed the presence of a reaction layer resulting from an interaction between Sn from the molten Sn-Pb and the glassy phase at the TKN/LTCC interface. The thick film porosity did not contribute, explicitly, to the occurrence of reaction layer. Rather, the process of printing the very thin conductor pads was too sensitive to minor thixotropic changes to ink, which resulted in inconsistent proportions of metal and glassy phase particles present during the subsequent firing process. The consequences were subtle, intermittent changes to the thick film microstructure that gave rise to the reaction layer and, thus, the low pull strength phenomenon. A mitigation strategy would be the use of physical vapor deposition (PVD) techniques to create thin film bond pads; this is multi-chip module, deposited (MCM-D) technology.

Fundamental Scratch Behavior of Styrene-Acrylonitrile Random Copolymers  

E-Print Network (OSTI)

The present study employs a standardized progressive load scratch test (ASTM D7027/ISO 19252) to investigate the fundamental physical and mechanistic origins of scratch deformation in styrene-acrylonitrile (SAN) random copolymers. Previous findings from numerical simulation using finite element methods are used to establish correlation between mechanical properties and key scratch deformation mechanisms of the SAN model systems. For SAN, the acrylonitrile (AN) content and molecular weight (MW) can be changed to alter mechanical properties such as tensile strength and ductility. The key scratch deformation mechanisms are identified as: scratch groove formation, scratch visibility, periodic micro-cracking and plowing. Groove formation has been correlated to the secant modulus at the compressive yield point while micro-cracking and plowing are related to the tensile strength of the material. The fundamentals and physical origins of scratch visibility are discussed. It is explained how unbiased evaluation is accomplished by means of an automatic digital image analysis software package (ASV®). Frictional behavior and the effects of scratch speed and moisture absorption are also addressed. Increasing the AN content and/or the MW of the SAN random copolymers generally enhances the scratch resistance of the material with regard to the onset of the key deformation mechanisms. Increasing the scratch speed increases the brittleness of the material, resulting in failure at lower applied loads. Moisture absorption increases with AN content and imparts a degree of plasticization as the moisture diffuses into the sub-surface. This plasticization initially results in a degradation of scratch resistance with respect to the key deformation mechanisms, but then, after saturation, the moisture on the surface provides lubrication and improves the scratch resistance. It is important to note that polymers are fundamentally different in nature, but the findings of this study serve as an important stepping stone down the path to a deeper understanding of polymer scratch behavior.

Alternative models of OPEC behavior  

Science Conference Proceedings (OSTI)

Since the 1973 oil price jump there has been considerable interest in the Organization of the Petroleum Exporting Countries (OPEC) and its role in the international oil market. However, most of the literature on this subject is mainly concerned with either a time-control problem in which the optimality and implication of certain market behavior is analyzed or a simulation of the oil market assuming a particular market behavior by OPEC members. Our objective in this preliminary research is to present a unified framework in which we construct models of viable alternative market behaviors for OPEC members assuming profit-maximization behavior. Each model will be specified as a system of nonlinear simultaneous equations, and for a particular functional forms specification, we present the estimates of the first two models considered.

Selected Area Fishery Evaluation Project Economic Analysis Study Final Report, Final Draft Revision 4: November 10, 2006.  

DOE Green Energy (OSTI)

The purpose of this Study is to provide an economic review of current and proposed changes to the Select Area Fishery Evaluation Project (SAFE or Project). The Study results are the information requested in comments made on the Project by a joint review dated March 2005 by the Northwest Power and Conservation Council (NPCC) Independent Scientific Review Panel (ISRP) and Independent Economic Analysis Board (IEAB). North et al. (2006) addressed technical questions about operations and plans, and this report contains the response information for comments concerning Project economics. This report can be considered an economic feasibility review meeting guidelines for cost-effective analysis developed by the IEAB (2003). It also contains other economic measurement descriptions to illustrate the economic effects of SAFE. The SAFE is an expansion of a hatchery project (locally called the Clatsop Economic Development Council Fisheries Project or CEDC) started in 1977 that released an early run coho (COH) stock into the Youngs River. The Youngs River entrance to the Columbia River at River Mile 12 is called Youngs Bay, which is located near Astoria, Oregon. The purpose of the hatchery project was to provide increased fishing opportunities for the in-river commercial fishing gillnet fleet. Instead of just releasing fish at the hatchery, a small scale net pen acclimation project in Youngs Bay was tried in 1987. Hirose et al. (1998) found that 1991-1992 COH broodstock over-wintered at the net pens had double the smolt-to-adult return rate (SAR) of traditional hatchery release, less than one percent stray rates, and 99 percent fishery harvests. It was surmised that smolts from other Columbia River hatcheries could be hauled to the net pens for acclimation and release to take advantage of the SAR's and fishing rates. Proposals were tendered to Bonneville Power Administration (BPA) and other agencies to fund the expansion for using other hatcheries smolts and other off-channel release sites. The BPA, who had been providing funds to the Project since 1982, greatly increased their financial participation for the experimental expansion of the net pen operations in 1993. Instead of just being a funding partner in CEDC operations, the BPA became a major financing source for other hatchery production operations. The BPA has viewed the 10 plus years of funding since then as an explorative project with two phases: a 'research' phase ending in 1993, and a 'development' phase ending in 2006. The next phase is referred to in proposals to BPA for continued funding as an 'establishment' phase to be started in 2007. There are three components of SAFE: (1) The CEDC owns and operates the net pens in the Columbia River estuary on the Oregon side. The CEDC also owns and operates a hatchery on the South Fork Klaskanine River. (2) There are many other hatcheries contributing smolts to the net pen operations. The present suite of hatcheries are operated by the Washington Department of Fish and Wildlife (WDFW) and Oregon Department of Fish and Wildlife (ODFW). The WDFW owns and operates the net pens at Deep River on the Washington side of the Columbia River. (3) The monitoring and evaluation (M&E) responsibilities are performed by employees of WDFW and ODFW. BPA provides funding for all three components as part of NPCC Project No. 199306000. The CEDC and other contributing hatcheries have other sources of funds that also support the SAFE. BPA's minor share (less than 10 percent) of CEDC funding in 1982 grew to about 55 percent in 1993 with the beginning of the development phase of the Project. The balance of the CEDC budget over the years has been from other federal, state, and local government programs. It has also included a 10 percent fee assessment (five percent of ex-vessel value received by harvesters plus five percent of purchase value made by processors) on harvests that take place in off-channel locations near the release sites. The CEDC total annual budget in the last several years has been in the $600 to $700 thousand range. The Project over

An important output is the flux-density pattern (W/cm/sup 2/) at a grid of points on a surface such as the absorbing surface of a receiver and its integral (power in watts) over the surface. The angular distribution of sunrays for the radiation incident on a concentrator is modified by convolution, using the fast Fourier transform, to incorporate the effects of other nondeterministic factors such as sun-tracking errors, surface slope errors, and reflectance properties. The analytical methods used for the statistics, the off-axis reflecting optics, the atmospheric effects, and the various coordinate systems are described and illustrated. This model forms a basis for the simulation code HELIOS as well as for other codes under development. Some of the HELIOS routines are described, a few of its capabilities are discussed and illustrated, and comparisons of data with calculations are presented. These capabilities have been used for performance predictions, safety studies, design trade-offs, data analysis problems, the specification and analysis of concentrator quality, and for the general understanding of solar-concentrator technology.

Decomposition of NH3BH3 at sub-ambient pressures: A combined thermogravimetry-differential thermal analysis-mass spectrometry study  

DOE Green Energy (OSTI)

We report a systematic study of the isothermal decomposition of ammonia borane, NH3BH3, at 363 K as a function of argon pressure ranging between 50 and 1040 mbar using thermogravimetry and differential thermal analysis coupled with mass analysis of the volatile species. During thermal aging at 363 K, evolution of hydrogen, aminoborane and borazine is monitored, with the relative mass loss strongly depending on the pressure in the reaction chamber. Furthermore, the induction period required for hydrogen release at 363 K decreases with decreasing pressure.

The Design and Analysis of Salmonid Tagging Studies in the Columbia Basin : Volume II: Experiment Salmonid Survival with Combined PIT-CWT Tagging.  

DOE Green Energy (OSTI)

Experiment designs to estimate the effect of transportation on survival and return rates of Columbia River system salmonids are discussed along with statistical modeling techniques. Besides transportation, river flow and dam spill are necessary components in the design and analysis otherwise questions as to the effects of reservoir drawdowns and increased dam spill may never be satisfactorily answered. Four criteria for comparing different experiment designs are: (1) feasibility, (2) clarity of results, (3) scope of inference, and (4) time to learn. In this report, alternative designs for conducting experimental manipulations of smolt tagging studies to study effects of river operations such as flow levels, spill fractions, and transporting outmigrating salmonids around dams in the Columbia River system are presented. The principles of study design discussed in this report have broad implications for the many studies proposed to investigate both smolt and adult survival relationships. The concepts are illustrated for the case of the design and analysis of smolt transportation experiments. The merits of proposed transportation studies should be measured relative to these principles of proper statistical design and analysis.

Convergence Studies of Thermal and Electromagnetic Transient Quench Analysis of 11 GeV Super High Momentum Spectrometer Superconducting Magnets in Jefferson Lab  

Science Conference Proceedings (OSTI)

This paper presents results of convergence studies of transient thermal and electromagnetic quench analysis of five Super High Momentum Spectrometer (SHMS) superconducting magnets: HB, Q1, Q2, Q3, and Dipole, using Vector Fields Quench analysis codes. The convergence of the hot spot temperature and solution solve times were used to investigate the effects of element types, mesh densities, and tolerance criteria. The comparisons between tetrahedral elements and hexahedral elements was studied, and their advantages and disadvantages were discussed. Based on the results of convergence studies, a meshing guideline for coils is presented. The impact of iteration tolerance to the hot spot temperature was also explored, and it is found that tight tolerances result in extremely long solve times with only marginal improvements in the results.

Thermal-fluid and electrochemical modeling and performance study of a planar solid oxide electrolysis cell : analysis on SOEC resistances, size, and inlet flow conditions.  

DOE Green Energy (OSTI)

Argonne National Laboratory and Idaho National Laboratory researchers are analyzing the electrochemical and thermal-fluid behavior of solid oxide electrolysis cells (SOECs) for high temperature steam electrolysis using computational fluid dynamics (CFD) techniques. The major challenges facing commercialization of steam electrolysis technology are related to efficiency, cost, and durability of the SOECs. The goal of this effort is to guide the design and optimization of performance for high temperature electrolysis (HTE) systems. An SOEC module developed by FLUENT Inc. as part of their general CFD code was used for the SOEC analysis by INL. ANL has developed an independent SOEC model that combines the governing electrochemical mechanisms based on first principals to the heat transfer and fluid dynamics in the operation of SOECs. The ANL model was embedded into the commercial STAR-CD CFD software, and is being used for the analysis of SOECs by ANL. The FY06 analysis performed by ANL and reported here covered the influence of electrochemical properties, SOEC component resistances and their contributing factors, SOEC size and inlet flow conditions, and SOEC flow configurations on the efficiency and expected durability of these systems. Some of the important findings from the ANL analysis are: (1) Increasing the inlet mass flux while going to larger cells can be a compromise to overcome increasing thermal and current density gradients while increasing the cell size. This approach could be beneficial for the economics of the SOECs; (2) The presence of excess hydrogen at the SOEC inlet to avoid Ni degradation can result in a sizeable decrease in the process efficiency; (3) A parallel-flow geometry for SOEC operation (if such a thing be achieved without sealing problems) yields smaller temperature gradients and current density gradients across the cell, which is favorable for the durability of the cells; (4) Contact resistances can significantly influence the total cell resistance and cell temperatures over a large range of operating potentials. Thus it is important to identify and avoid SOEC stack conditions leading to such high resistances due to poor contacts.

Location of hydrogen adsorbed on Rh(111) studied by low-energy electron diffraction and nuclear reaction analysis  

Science Conference Proceedings (OSTI)

The structures of clean and hydrogen-adsorbed Rh(111) surfaces were investigated by dynamical low-energy electron-diffraction (LEED) analysis. Exposure of D{sub 2} induced no additional LEED patterns except for (1x1). Surface-layer relaxation occurs vertically on both clean and D-saturated surfaces. On the clean surface, the interlayer distance between the first and second layers (d{sub 12}) is smaller by 1.2({+-}0.6)% than the corresponding bulk distance of 2.194 A. On the other hand, the contraction of d{sub 12} is removed on the D-saturated surface. Detailed LEED analysis demonstrates that the D atoms are adsorbed on the fcc threefold hollow sites. The absolute saturation coverage of H on Rh(111) was determined to be 0.84 ML by nuclear reaction analysis (NRA). Moreover, the zero-point vibrational energy of H was derived from the analysis of the NRA resonance profile, which is discussed in comparison with the results of high-resolution electron-energy-loss spectroscopy.

Comprehensive Video Ethogram on Beluga (Delphinapterus leucas) Behavior  

E-Print Network (OSTI)

Research is limited for belugas in both the wild and in the care of humans. To address this lack of knowledge, I created a comprehensive video ethogram of beluga behavior, collected from the beluga population located at Sea World San Antonio. The purpose of this study was to create an educational tool to train future research observers and to increase public awareness. Video recordings were taken from above water and then imported into video editing software. A total of 103 videos were reviewed, which represented 24 hours 49 minutes of video data. Each video was examined for the best examples of each behavior of interest. Clips of these behaviors were recorded and edited together into a single video paired with a voiceover commentary to explain the clip. The video ethogram comprises 82 percent of the behaviors in the comprehensive ethogram. A total of 268 clips of behaviors are in the video. The full running length of the video ethogram is 1 hour 5 minutes 2.03 seconds. Of all the potential behaviors, 64 percent were found to be frequent and 36 percent were found to be rare. The video portion provides visual examples of the behavior while the voiceover commentary provides explanations. Due to the lack of a comprehensive ethogram in the literature and time consuming process of training observers, this video ethogram is a necessary and practical addition to the study of belugas.

Integrated systems analysis of the PIUS reactor  

SciTech Connect

Results are presented of a systems failure analysis of the PIUS plant systems that are used during normal reactor operation and postulated accidents. This study was performed to provide the NRC with an understanding of the behavior of the plant. The study applied two diverse failure identification methods, Failure Modes Effects & Criticality Analysis (FMECA) and Hazards & Operability (HAZOP) to the plant systems, supported by several deterministic analyses. Conventional PRA methods were also used along with a scheme for classifying events by initiator frequency and combinations of failures. Principal results of this study are: (a) an extensive listing of potential event sequences, grouped in categories that can be used by the NRC, (b) identification of support systems that are important to safety, and (c) identification of key operator actions.

Individual energy conservation behaviors  

Science Conference Proceedings (OSTI)

One important basis for sound energy policy is an understanding of how American consumers view and practice energy conservation. This volume reports the results of Project Monitor, a study of consumers' energy attitudes and behaviour. More than 1000 household consumers were interviewed to determine individual attributes, situational factors, attitudes, and perceptions that influence (or fail to influence) energy conservation. Using these data, the authors related specific types of energy conservation-general, winterization, heating, cooling, appliance, transportation, and electricity reductions-to twenty-four demographic, situational, attitudinal, and perceptual variables in the household sample. To determine the characteristics that differentiate conservers from nonconservers, simple correlations are made between each of the ''independent'' variables and the ''dependent'' measures of conservation and the results of multivariate regression analyses are used to estimate the effects of the independent variables simultaneously.

Fighting behavior in Bald Eagles: a test of game theory. [Haliaeetus leucocephalus  

Science Conference Proceedings (OSTI)

Seven predictions of evolutionary game theory were examined in field studies of foraging behavior of Bald Eagles (Haliaeetus leucocephalus) wintering in the Chilkat Valley, Alaska. A cost/benefit analysis revealed that the frequencies of two foraging strategies (hunting and stealing from conspecifics) were balanced such that the payoffs of the two were nearly equal. Asymmetries in probable correlates of fighting ability (size and, possibly, spatial position (being in the air vs. on the ground), but not age) and expected gain in victory (hunger level) influenced the outcome of contests over food. Individuals used conditions strategies: small or young birds appeared to hung (rather than steal) relatively more often than others. Pirating eagles often assessed the size and hunger level of food defenders and attacked those most likely to retreat. Contrary to prediction, ritualized displays served to advertise expected gain in victory and were good indicators of subsequent behavior. The level of escalated fighting was inversely related to resource availability. Finally, a graphical model shows that pirating frequency may or may not be influenced by changes in food abundance. The results generally support the predictions of game theory and explain several aspects of Bald Eagle foraging behavior.

Oxygen chemisorption on Cu(19 19 1) studied by spot profile analysis low-energy electron diffraction  

SciTech Connect

Cu(110) and the vicinal Cu(19 19 1) surfaces were characterized by recording maps of the reciprocal space by means of spot profile analysis low-energy electron diffraction (SPA-LEED). For both surfaces, kinematic simulations were performed to get insight into the main features of the experimental data. Furthermore, it is shown that chemisorption of oxygen and subsequent annealing lead to the formation of a Cu-CuO stripe phase and induce faceting of the Cu(19 19 1) surface. The evolution from the clean Cu(19 19 1) surface to the coexistence of the (110) and (111) facets with increasing oxygen exposure was characterized by SPA-LEED.

An experimental study of assessment of weld quality on fatigue reliability analysis of a nuclear pressure vessel  

SciTech Connect

The steam generator in a PWR primary coolant system is one of the pieces of equipment made in China for the Qinshan nuclear power plant, Zhejiang. It is a crucial unit belonging to the category of nuclear pressure vessel. The purpose of this research work is to carry out an examination of the weld quality of the steam generator under fatigue loading and to assess its reliability by using experimental results of a fatigue test of the nuclear pressure vessel steel S-271 (Chinese Standard) and of qualified tests of welded seams of a simulated prototype of the bottom closure head of the steam generator. A guarantee of weld quality is proposed as the quality assurance of safety for the China National Nuclear Safety Supervision Bureau. The results of the reliability analysis reported in this work can be taken as supplementary material for a Probabilistic Risk Assessment (PRA) of the Qinshan nuclear power plant. According to the requirement of Provision 2-1500 CYCLIC TESTING, ASME Boiler and Pressure Vessel Code, Section 3, Rules for Construction of Nuclear Power Plant Components, a simulated prototype of the bottom closure head of the steam generator was made in this work for the qualified tests. Qualified tests with small sample size present a problem which is difficult to solve in reliability analysis, and are therefore of interest. Here, the authors offer proposals attempting to solve this problem.

An Analysis of Wind Power Development in the Town of Hull, MA, Appendix 2: LaCapra Financial Study  

SciTech Connect

The financial analysis and summary results presented in this document represent a first cut at an economic assessment of the proposed Hull Offshore Wind Project. Wind turbine price increases have outpaced the materials and labor price pressures faced by nonrenewable power plant developers due to increased demands on a limited pool of turbine manufacturers and offshore installation companies. Moreover, given the size of the proposed offshore facility, it may be difficult to contract with turbine manufacturers and/or foundation companies given the size and scope of competing worldwide demand. The results described in this report assume that such conditions will not significantly impact the prices that will have to be received from the output of the project; rather, the project size may require as a prerequisite that Hull be able to piggyback on other offshore efforts. The financial estimates provided here necessarily feature a range due to uncertainty in a number of project assumptions as well as overall uncertainty in offshore wind costs. Nevertheless, taken together, the analysis provides a ballpark revenue requirement of approximately $157/MWh for the municipal financing option, with higher estimates possible assuming escalation in costs to levels higher than assumed here.

DOE Green Energy (OSTI)

The object of this phase of the program has been to investigate the effects of various processes, metal contaminants and contaminant-process interactions on the properties of silicon and on the performance of terrestrial silicon solar cells. The study encompassed topics including thermochemical (gettering) treatments, base doping concentration, base doping type (n vs. p), grain boundary-impurity interaction, non-uniformity of impurity distribution, long term effects of impurities, as well as synergic and complexing phenomena. The program approach consists in: (1) the growth of doubly and multiply-doped silicon single crystals containing a baseline boron or phosphorus dopant and specific impurities which produce deep levels in the forbidden band gap; (2) assessment of these crystals by chemical, microstructural, electrical and solar cell tests; (3) correlation of the impurity type and concentration with crystal quality and device performance; and (4) delineation of the role of impurities and processing on subsequent silicon solar cell performance. The overall results reported are based on the assessment of nearly 200 silicon ingots. (WHK)

Isoscaling behavior in the Fission Dynamics  

E-Print Network (OSTI)

The fission processes of $^{112}$Sn + $^{112}$Sn and $^{116}$Sn + $^{116}$Sn are simulated with the combination of the Langevin equation and the statistical decay model. The masses of two fission fragments are given by assuming the process of symmetric fission or asymmetric fission by the Monte Carlo sampling with the Gaussian probability distribution. From the analysis to the isotopic/isotonic ratios of the fission fragments from both reactions, the isoscaling behavior has been observed and investigated in details. Isoscaling parameters $\\alpha$ and $\\beta$ are extracted as a function of the charge number and neutron number, respectively, in different width of the sampling Gaussian probability distribution. It seems that $\\alpha$ is sensitive to the width of fission probability distribution of the mass asymmetrical parameter but $\\beta$ is not. Both $\\alpha$ and $\\beta$ drop with the increasing of beam energy and the reduced friction parameter.

Online elemental analysis of process gases with ICP-OES: A case study on waste wood combustion  

SciTech Connect

Highlights: Black-Right-Pointing-Pointer Simultaneous measurements of 23 elements in process gases of a waste wood combustor. Black-Right-Pointing-Pointer Mobile ICP spectrometer allows measurements of high quality at industrial plants. Black-Right-Pointing-Pointer Continuous online measurements with high temporal resolution. Black-Right-Pointing-Pointer Linear correlations among element concentrations in the raw flue gas were detected. Black-Right-Pointing-Pointer Novel sampling and calibration methods for ICP-OES analysis of process gases. - Abstract: A mobile sampling and measurement system for the analysis of gaseous and liquid samples in the field was developed. An inductively coupled plasma optical emission spectrometer (ICP-OES), which is built into a van, was used as detector. The analytical system was calibrated with liquid and/or gaseous standards. It was shown that identical mass flows of either gaseous or liquid standards resulted in identical ICP-OES signal intensities. In a field measurement campaign trace and minor elements in the raw flue gas of a waste wood combustor were monitored. Sampling was performed with a highly transport efficient liquid quench system, which allowed to observe temporal variations in the elemental process gas composition. After a change in feedstock an immediate change of the element concentrations in the flue gas was detected. A comparison of the average element concentrations during the combustion of the two feedstocks showed a high reproducibility for matrix elements that are expected to be present in similar concentrations. On the other hand elements that showed strong differences in their concentration in the feedstock were also represented by a higher concentration in the flue gas. Following the temporal variations of different elements revealed strong correlations between a number of elements, such as chlorine with sodium, potassium and zinc, as well as arsenic with lead, and calcium with strontium.

Aging behavior of polymeric solar absorber materials - Part 2: Commodity plastics  

SciTech Connect

In this series of two papers, various polymeric materials are investigated as to their potential applicability as absorber materials for solar thermal collectors. While Part 1 of this paper series deals with the aging behavior of engineering plastics, including two amorphous polymers (PPE + PS) and (PC) and two semi-crystalline polymers (two types of PA12), the present Part 2 treats the aging behavior of semi-crystalline so-called ''commodity'' plastics (two types of crosslinked polyethylene (PE-X) and two types of polypropylene (PP)). As in Part 1, the focus of the investigation is to study the aging behavior of these materials under maximum operating conditions (80 C in water up to 16,000 h) and stagnation conditions (140 C in air up to 500 h) typical for northern climate. The materials supplied or produced as polymer films were first characterized in the unaged state and then for different states of aging by differential scanning calorimetry (DSC), by size exclusion chromatography (SEC) and by mechanical tensile tests. DSC was applied primarily to obtain information on physical aging phenomena, whereas SEC analysis was used to characterize chemical degradation of the materials. In addition, physical and chemical aging were both analyzed via the small and large strain mechanical behavior. Comparing the two aging conditions in hot air and hot water, a rather stable mechanical performance profile was found for both PP types over the investigated aging time, which was interpreted in terms of competing physical and chemical aging mechanisms. Analogously such competing mechanisms were also inferred for one of the PE-X materials, while the other exhibited substantial degradation in terms of strain-to-break values for both aging conditions. In principle, both PP and PE-X are promising candidates for black absorber applications in northern climates if proper measures against overheating are taken and when adequately modified. (author)

Global Assessment of Hydrogen Technologies – Tasks 3 & 4 Report Economic, Energy, and Environmental Analysis of Hydrogen Production and Delivery Options in Select Alabama Markets: Preliminary Case Studies  

Science Conference Proceedings (OSTI)

This report documents a set of case studies developed to estimate the cost of producing, storing, delivering, and dispensing hydrogen for light-duty vehicles for several scenarios involving metropolitan areas in Alabama. While the majority of the scenarios focused on centralized hydrogen production and pipeline delivery, alternative delivery modes were also examined. Although Alabama was used as the case study for this analysis, the results provide insights into the unique requirements for deploying hydrogen infrastructure in smaller urban and rural environments that lie outside the DOE’s high priority hydrogen dep
