Corona losses in HVdc bipolar lines  

SciTech Connect

The problem related to the prediction of corona losses in HVdc bipolar lines has been solved, in the past, by means of semi-empirical monomial formulae. However, the proposed formulae that are simpler to use do not always give adequate calculation precision, while the formulae that provide the closest results require implicit functions of different complexity, which are difficult to apply; moreover, it is not possible to understand clearly what influence the variations of the different line parameters have on the losses themselves. The new monomial semi-empirical relationship, proposed to predict the corona losses in HVdc bipolar lines, is very simple to use; it highlights the dependence of power losses due to the corona effect by the different line parameters. The formula has been developed by elaborating a considerable amount of available experimental data.

Loss of line shutdown for line-commutated utility-interactive inverter  

SciTech Connect

The line-commutated, single-phase, utility-interactive inverter has been used in utility-connected photovoltaic (PV) and wind energy systems because it is commercially available at an attractive price. If unity power factor operation is required, a shunt capacitor can be used. This causes a problem if the utility line is disconnected; the inverter can continue to run and can thus be a hazard. This can be solved by using a fast-acting overvoltage detection circuit which operates directly on the inverter control electronics.

Quasi-Static Conductor Loss Calculations in Transmission Lines using a New Conformal Mapping Technique  

E-Print Network (OSTI)

Abstract- A new approximation technique to find the total series impedance per unit length for quasi-TEM transmission lines including conductor loss has been developed. It is shown through the use of conformal mapping that both frequency dependent skin-depth and proximity effects can be accurately modeled. Comparison between experimental measurements and calculations for twin-lead, coplanar strips, parallel square bars, and coplanar waveguide all show excellent agreement. This technique is easily generalized to any transmission line making use of polygonal cross-section conductors. I.

Numerical study of electron-leakage power loss in a tri-plate transmission line  

SciTech Connect

Numerical simulations have been conducted using NRL's DIODE2D computer code to model the steady-state behavior of electron flow in a radial diode and in its adjacent tri-plate transmission line (TTL). Particular attention was paid to the magnitude of the electron current flowing from the cathode to the anode surface in the TTL. A quantitative value for this effective power loss is given. The electron current is restricted mainly to the transition region in the TTL into which there is seepage of the B/sub z/ that is imposed in the diode gap. This finding highlights the importance of that region to diode designers.

Depinning of flux lines and AC losses in magnet-superconductor levitation system  

DOE Green Energy (OSTI)

The AC loss characteristics of a magnet-superconductor system were studied with the magnet fixed to the free end of an oscillating cantilever located near a stationary melt-textured YBCO pellet. Below a threshold AC field amplitude {approx}2Oe, the dissipation of the oscillator is amplitude-independent, characteristic of a linear, non-hysteretic regime. Above threshold,dissipation increases with amplitude, reflecting the depinning and hysteretic motion of flux lines. The threshold AC field is an order of magnitude higher than that measured for the same YBCO material via AC susceptometry in a uniform DC magnetic field, A partial lock-in of flux lines between YBCO ab planes is proposed as the mechanism for the substantial increase of the depinning threshold.

Influence of the airflow speed along transmission lines on the DC corona discharge loss, using finite element approach  

SciTech Connect

Corona discharge is of great interest from the physical point of view and due to its numerous practical applications in industry and especially one of the most important sources of loss in the high voltage transmission lines. This paper provides guidelines for the amount of electric loss caused by corona phenomenon occurred around a DC high voltage wire placed between two flat plates and influence of wind speed rate on the amount of corona loss using COMSOL Multiphysics. So electric potential distribution patterns and charge density diffusion around the wire are studied in this article.

Beam Loss Studies for the 2-MW LBNE Proton Beam Line  

SciTech Connect

Severe limits are put on allowable beam loss during extraction and transport of a 2.3 MW primary proton beam for the Long Baseline Neutrino Experiment (LBNE) at Fermilab. Detailed simulations with the STRUCT and MARS codes have evaluated the impact of beam loss of 1.6 x 10{sup 14} protons per pulse at 120 GeV, ranging from a single pulse full loss to sustained small fractional loss. It is shown that loss of a single beam pulse at 2.3 MW will result in a catastrophic event: beam pipe destruction, damaged magnets and very high levels of residual radiation inside and outside the tunnel. Acceptable beam loss limits have been determined and robust solutions developed to enable efficient proton beam operation under these constraints.

Single and three-phase AC losses in HTS superconducting power transmission line prototype cables  

SciTech Connect

AC losses in two, one-meter-long lengths of HTS prototype multi-strand conductors (PMC`s) are measured with a temperature-difference calorimeter. Both single-phase and three-phase losses are examined with ac currents up to 1,000 A rms. The calorimeter, designed specifically for these measurements, has a precision of 1 mW. PMC {number_sign}1 has two helically-wound, non-insulated layers of HTS tape (19 tapes per layer), each layer wrapped with opposite pitch. PMC {number_sign}2 is identical except for insulation between the layers. The measured ac losses show no significant effect of interlayer insulation and depend on about the third power of the current--a result in agreement with the Bean-Norris model adapted to the double-helix configuration. The three-phase losses are a factor of two higher than those exhibited by a single isolated conductor, indicating a significant interaction between phases.

Auger line shape and electron energy loss spectroscopy analysis of amorphous, microcrystalline, and. beta. -SiC  

DOE Green Energy (OSTI)

Auger electron spectroscopy (AES) line shape analysis of the Si-{ital L}{sub 23}{ital VV} and C-{ital KLL} peaks has been performed in conjunction with electron energy loss spectroscopy (EELS) on Hg-sensitized photodeposited amorphous and microcyrstalline SiC films. Mixtures of SiH{sub 4}/CH{sub 3}SiH{sub 3} and SiH{sub 4}/(CH{sub 3}){sub 2}SiH{sub 2} with helium or hydrogen dilution were used for the depositions. AES line shape and EELS analyses were also performed on {beta}-SiC for comparison. Quantitative bulk compositional analysis to determine the Si and C concentrations in these films was performed with an electron microprobe (EMPA) using x-ray wavelength dispersive spectroscopy (WDS). AES and EELS results reveal the predominant Si--C bonding and relative crystallinity in the films as a function of deposition parameters, which includes the gas mixture, pressure, and H{sub 2}/He dilution. These parameters determine the H radical flux during growth, which leads to changes in the film structure.

THE TRANSITION MASS-LOSS RATE: CALIBRATING THE ROLE OF LINE-DRIVEN WINDS IN MASSIVE STAR EVOLUTION  

Science Conference Proceedings (OSTI)

A debate has arisen regarding the importance of stationary versus eruptive mass loss for massive star evolution. The reason is that stellar winds have been found to be clumped, which results in the reduction of unclumped empirical mass-loss rates. Most stellar evolution models employ theoretical mass-loss rates which are already reduced by a moderate factor of {approx_equal}2-3 compared to non-corrected empirical rates. A key question is whether these reduced rates are of the correct order of magnitude, or if they should be reduced even further, which would mean that the alternative of eruptive mass loss becomes necessary. Here we introduce the transition mass-loss rate M-dot{sub trans} between O and Wolf-Rayet stars. Its novelty is that it is model independent. All that is required is postulating the spectroscopic transition point in a given data set, and determining the stellar luminosity, which is far less model dependent than the mass-loss rate. The transition mass-loss rate is subsequently used to calibrate stellar wind strength by its application to the Of/WNh stars in the Arches cluster. Good agreement is found with two alternative modeling/theoretical results, suggesting that the rates provided by current theoretical models are of the right order of magnitude in the {approx}50 M{sub Sun} mass range. Our results do not confirm the specific need for eruptive mass loss as luminous blue variables, and current stellar evolution modeling for Galactic massive stars seems sound. Mass loss through alternative mechanisms might still become necessary at lower masses, and/or metallicities, and the quantification of alternative mass loss is desirable.

Groups defined by automata  

E-Print Network (OSTI)

This is Chapter 24 in the "AutoMathA" handbook. Finite automata have been used effectively in recent years to define infinite groups. The two main lines of research have as their most representative objects the class of automatic groups (including word-hyperbolic groups as a particular case) and automata groups (singled out among the more general self-similar groups). The first approach implements in the language of automata some tight constraints on the geometry of the group's Cayley graph, building strange, beautiful bridges between far-off domains. Automata are used to define a normal form for group elements, and to monitor the fundamental group operations. The second approach features groups acting in a finitely constrained manner on a regular rooted tree. Automata define sequential permutations of the tree, and represent the group elements themselves. The choice of particular classes of automata has often provided groups with exotic behaviour which have revolutioned our perception of infinite finitely ge...

PVMaT cost reductions in the EFG high volume PV manufacturing line: Annual report, 5 August 1998--4 August 1999[PhotoVoltaic Manufacturing Technology, Edge-defined Film-fed Growth  

DOE Green Energy (OSTI)

This report describes work performed by ASE Americas researchers during the first year of this Photovoltaic Manufacturing Technology 5A2 program. Significant accomplishments in each of three task are as follows. Task 1--Manufacturing Systems: Researchers completed key node analysis, started statistical process control (SPC) charting, carried out design-of-experiment (DoE) matrices on the cell line to optimize efficiencies, performed a capacity and bottleneck study, prepared a baseline chemical waste analysis report, and completed writing of more than 50% of documentation and statistical sections of ISO 9000 procedures. A highlight of this task is that cell efficiencies in manufacturing were increased by 0.4%--0.5% absolute, to an average in excess of 14.2%, with the help of DoE and SPC methods. Task 2--Low-Cost Processes: Researchers designed, constructed, and tested a 50-cm-diameter, edge-defined, film-fed growth (EFG) cylinder crystal growth system to successfully produce thin cylinders up to 1.2 meters in length; completed a model for heat transfer; successfully deployed new nozzle designs and used them with a laser wafer-cutting system with the potential to decrease cutting labor costs by 75% and capital costs by 2X; achieved laser-cutting speeds of up to 8X and evaluation of this system is proceeding in production; identified laser-cutting conditions that reduce damage for both Q-switched Nd:YAG and copper-vapor lasers with the help of a breakthrough in fundamental understanding of cutting with these short-pulse-length lasers; and found that bulk EFG material lifetimes are optimized when co-firing of silicon nitride and aluminum is carried out with rapid thermal processing (RTP). Task 3--Flexible Manufacturing: Researchers improved large-volume manufacturing of 10-cm {times} 15-cm EFG wafers by developing laser-cutting fixtures, adapting carriers and fabricating adjustable racks for etching and rinsing facilities, and installing a high-speed data collection net work; initiated fracture studies to develop methods to reduce wafer breakage; and started a module field studies program to collect data on field failures to help identify potential manufacturing problems. New encapsulants, which cure at room temperature, are being tested to improve flexibility and provide higher yields for thin wafers in lamination.

Flu Terms Defined  

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

Flu Terms Defined Flu Terms Defined H1N1 Influenza is a respiratory disease of pigs caused by type A influenza viruses that causes regular outbreaks in pigs. People do not normally get H1N1 flu, but human infections can and do happen. H1N1 flu viruses have been reported to spread from person-to-person, but in the past, this transmission was limited and not sustained beyond three people. Avian flu (AI) is caused by influenza viruses that occur naturally among wild birds. Low pathogenic AI is common in birds and causes few problems. Highly pathogenic H5N1 is deadly to domestic fowl, can be transmitted from birds to humans, and is deadly to humans. There is virtually no human immunity and human vaccine availability is very limited. Pandemic flu is virulent human flu that causes a global outbreak, or pandemic, of serious illness. Because there is little natural immunity, the disease can spread easily from person to person. Currently, there is no pandemic flu.

Defining resilience within a risk-informed assessment framework  

Science Conference Proceedings (OSTI)

The concept of resilience is the subject of considerable discussion in academic, business, and governmental circles. The United States Department of Homeland Security for one has emphasised the need to consider resilience in safeguarding critical infrastructure and key resources. The concept of resilience is complex, multidimensional, and defined differently by different stakeholders. The authors contend that there is a benefit in moving from discussing resilience as an abstraction to defining resilience as a measurable characteristic of a system. This paper proposes defining resilience measures using elements of a traditional risk assessment framework to help clarify the concept of resilience and as a way to provide non-traditional risk information. The authors show various, diverse dimensions of resilience can be quantitatively defined in a common risk assessment framework based on the concept of loss of service. This allows the comparison of options for improving the resilience of infrastructure and presents a means to perform cost-benefit analysis. This paper discusses definitions and key aspects of resilience, presents equations for the risk of loss of infrastructure function that incorporate four key aspects of resilience that could prevent or mitigate that loss, describes proposed resilience factor definitions based on those risk impacts, and provides an example that illustrates how resilience factors would be calculated using a hypothetical scenario.

Defining a Standard Metric for Electricity Savings  

SciTech Connect

The growing investment by governments and electric utilities in energy efficiency programs highlights the need for simple tools to help assess and explain the size of the potential resource. One technique that is commonly used in this effort is to characterize electricity savings in terms of avoided power plants, because it is easier for people to visualize a power plant than it is to understand an abstraction such as billions of kilowatt-hours. Unfortunately, there is no standardization around the characteristics of such power plants. In this letter we define parameters for a standard avoided power plant that have physical meaning and intuitive plausibility, for use in back-of-the-envelope calculations. For the prototypical plant this article settles on a 500 MW existing coal plant operating at a 70percent capacity factor with 7percent T&D losses. Displacing such a plant for one year would save 3 billion kW h per year at the meter and reduce emissions by 3 million metric tons of CO2 per year. The proposed name for this metric is the Rosenfeld, in keeping with the tradition among scientists of naming units in honor of the person most responsible for the discovery and widespread adoption of the underlying scientific principle in question--Dr. Arthur H. Rosenfeld.

The line-above-ground attenuator provides a continuously variable microwave attenuator for a coaxial line that is capable of high attenuation and low insertion loss. The device consists of a short section of the line-above- ground plane type transmission lime, a pair of identical rectangular slabs of lossy material like polytron, whose longitudinal axes are parallel to and indentically spaced away from either side of the line, and a geared mechanism to adjust amd maintain this spaced relationship. This device permits optimum fineness and accuracy of attenuator control which heretofore has been difficult to achieve.

Distribution System Losses Evaluation  

Science Conference Proceedings (OSTI)

Currently, there is not an industry standard on how utilities calculate and account for electrical losses and reductions in electric system losses. Computer models used to analyze power flows typically only include the primary components of the distribution system infrastructure. More detailed electric system models can benefit utilities by providing more accurate loss calculations as well as benefits for system planning and engineering. The utility industry could benefit from having a consistent and uni...

Energy losses in switches  

DOE Green Energy (OSTI)

The authors experiments show energy losses between 2 and 10 times that of the resistive time predictions. The experiments used hydrogen, helium, air, nitrogen, SF{sub 6} polyethylene, and water for the switching dielectric. Previously underestimated switch losses have caused over predicting the accelerator outputs. Accurate estimation of these losses is now necessary for new high-efficiency pulsed power devices where the switching losses constitute the major portion of the total energy loss. They found that the switch energy losses scale as (V{sub peak}I{sub peak}){sup 1.1846}. When using this scaling, the energy losses in any of the tested dielectrics are almost the same. This relationship is valid for several orders of magnitude and suggested a theoretical basis for these results. Currents up to .65 MA, with voltages to 3 MV were applied to various gaps during these experiments. The authors data and the developed theory indicates that the switch power loss continues for a much longer time than the resistive time, with peak power loss generally occurring at peak current in a ranging discharge instead of the early current time. All of the experiments were circuit code modeled after developing a new switch loss version based on the theory. The circuit code predicts switch energy loss and peak currents as a function of time. During analysis of the data they noticed slight constant offsets between the theory and data that depended on the dielectric. They modified the plasma conductivity for each tested dielectric to lessen this offset.

B Plant ion exchange feed line leak  

SciTech Connect

>One of the objectives of the Waste Management Program is to separate the long-lived heat emitter /aup 137/Cs from the bulk of the high-level Iiquid wastes. This separation is accomplished by the ion exchange process in the 221-B Building. Interim storage of the cesium is in solution as a nitrate. The feed for the B Plant cesinm ion exchange process is pumped from the lag storage tank, 105-C, through a pipeline and several diversion boxes to the 221-B Building. On December 19, 1969, a leak was discovered near the 241-C-152 diversion box in the section of this line, V-122, from the 105-C tank. Although the leak represented a loss of feed for the processing of /sup 137/Cs, more important was the consequence of environmental contmination to the soil from the line leak. For this reason, an investigation was made to estblish the extent of the radioactivity spread. The results of a well drilling operation undertaken to define the boundary and to estimate the extent of the leak are summarized. (CR)

What Defines a Separate Hydrothermal System  

DOE Green Energy (OSTI)

Separate hydrothermal systems can be defined in a variety of ways. Criteria which have been applied include separation of heat source, upflow, economic resource and geophysical anomaly. Alternatively, connections have been defined by the effects of withdrawal of economically useful fluid and subsidence, effects of reinjection, changes in thermal features, or by a hydrological connection of groundwaters. It is proposed here that: ''A separate hydrothermal system is one that is fed by a separate convective upflow of fluid, at a depth above the brittle-ductile transition for the host rocks, while acknowledging that separate hydrothermal systems can be hydrologically interconnected at shallower levels''.

Software-defined Quantum Communication Systems  

SciTech Connect

We show how to extend the paradigm of software-defined communication to include quantum communication systems. We introduce the decomposition of a quantum communication terminal into layers separating the concerns of the hardware, software, and middleware. We provide detailed descriptions of how each component operates and we include results of an implementation of the super-dense coding protocol. We argue that the versatility of software-defined quantum communication test beds can be useful for exploring new regimes in communication and rapidly prototyping new systems.

Stepwise method determines source of FCC catalyst losses  

Science Conference Proceedings (OSTI)

A set of guidelines for fluid catalytic cracking unit (FCCU) monitoring and a logical, stepwise approach to troubleshooting FCC catalyst losses is discussed. This will help process or operations engineers find the causes of such losses. A thorough understanding of the entire catalyst stem during normal operations establishes the base line data necessary for troubleshooting. A comprehensive, ongoing analysis of catalyst losses include: catalyst balance, fresh catalyst physical properties, equilibrium catalyst properties, fine particle size distribution, pressure surveys, and line and restriction orifice records. The paper goes on to identify each step in monitoring these operations and properties.

DOE Green Energy (OSTI)

Reliable systems are an essential ingredient of any technology progressing toward commercial maturity and large-scale deployment. This paper defines reliability as meeting system fictional requirements, and then develops a framework to understand and quantify photovoltaic system reliability based on initial and ongoing costs and system value. The core elements necessary to achieve reliable PV systems are reviewed. These include appropriate system design, satisfactory component reliability, and proper installation and servicing. Reliability status, key issues, and present needs in system reliability are summarized for four application sectors.

System Assessment Standards: Defining the Market for Assessment Services  

E-Print Network (OSTI)

Improved system efficiency can contribute to an industrial facility’s bottom line and also improve reliability and better utilize assets. Despite these opportunities, many industrial facilities continue to have unrealized system optimization potential. A significant barrier to realizing this potential is the lack of market definition for system energy efficiency assessment services. This creates problems for service providers in establishing market value for their services and problems for consumers in determining the relative quality of assessment service offerings. Achieving certification for energy efficiency will require industrial facilities to document a specified reduction in energy intensity. Application of System Assessment Standards will offer industrial facilities seeking certification a well-defined path toward improved energy intensity. System Assessment Standards will help define the market for both users and providers of industrial system assessment services. Use of these standards will provide assurance that a particular assessment represents a recognized threshold for accuracy and completeness. The goal is a significant increase in system energy efficiency improvements in U.S. industry.

Defining and testing a granular continuum element  

Science Conference Proceedings (OSTI)

Continuum mechanics relies on the fundamental notion of amesoscopic volume "element" in which properties averaged over discreteparticles obey deterministic relationships. Recent work on granularmaterials suggests a continuum law may be inapplicable, revealinginhomogeneities at the particle level, such as force chains and slow cagebreaking. Here, we analyze large-scale Discrete-Element Method (DEM)simulations of different granular flows and show that a "granularelement" can indeed be defined at the scale of dynamical correlations,roughly three to five particle diameters. Its rheology is rather subtle,combining liquid-like dependence on deformation rate and solid-likedependence on strain. Our results confirm some aspects of classicalplasticity theory (e.g., coaxiality of stress and deformation rate),while contradicting others (i.e., incipient yield), and can guide thedevelopment of more realistic continuum models.

Defining nuclear security in the 21st century  

Science Conference Proceedings (OSTI)

A conference devoted to Reducing the Risks from Radioactive and Nuclear Materials presupposes that such risks exist. Few would disagree, but what are they? While debate on the nature and severity of risks associated with nuclear energy will always remain, it is easy to define a set of risks that are almost universally acknowledged. These include: (1) Nuclear warfare between states; (2) Continued proliferation of nuclear weapons and weapons-grade nuclear materials to states and non-state actors; (3) Terrorists or non-state actor acquisition or use nuclear weapons or nuclear materials; (4) Terrorists or non-state actors attack on a nuclear facility; and (5) Loss or diversion of nuclear weapons or materials by a state to unauthorized uses. These are listed in no particular order of likelihood or potential consequence. They are also very broadly stated, each one could be broken down into a more detailed set of discrete risks or threats. The fact that there is a strong consensus on the existence of these risks is evidence that we remain in an era of nuclear insecurity. This becomes even clearer when we note that most major trends influencing the probability of these risks continue to run in a negative direction.

System Losses and Assessment Trade Study  

SciTech Connect

This Advanced Fuel Cycle Initiative (AFCI) study has developed new analysis methods to examine old and new technology options toward the goal of improving fuel cycle systems. We have integrated participants and information from AFCI Systems Analysis, Transmutation Fuels, Separations, and Waste Form Campaigns in the Systems Losses and Assessment Trade Study. The initial objectives of this study were to 1) increase understanding of system interdependencies and thereby identify system trade-offs that may yield important insights, 2) define impacts of separations product purity on fuel manufacture and transmutation reactivity, 3) define impacts from transuranic (TRU) losses to waste, 4) identify the interrelationships involved in fuels and separations technology performance, and 5) identify system configuration adjustments with the greatest potential for influencing system losses. While bounding and analyzing this initial problem, we also identified significantly higher-level programmatic drivers with broad implications to the current fuel cycle research charter and the general issue of a DOE complex wide need for a comprehensive and integrated nuclear material management as addressed by the new DOE Order 410.2 titled “Management of Nuclear Materials”. The initial modeling effort developed in this study for a much smaller subset of material (i.e., commercial fuel) and a selected transmutation scheme (i.e., fast reactor recycling) is a necessary first step towards examining a broader set of nuclear material management options, dispositioning strategies and integrated waste management options including potential areas of research leverage. The primary outcome from this initial study has been an enhanced integration among Campaigns and associated insights and analysis methods. Opportunities for improved understanding between the groups abound. The above lanthanide-actinide example highlights the importance of evaluating options via integration across the Campaigns. Plans for Fiscal Year 2010 are being made in a coordinated fashion such that the knowledge gained from the research performed by the Campaigns can benefit on-going work of the study, and that improved understanding of the system relationships can be used to guide the specific research and development (R&D) activities within the Campaigns. In FY-10, the System Losses and Assessment Trade Study will carry-over activities from FY-09. We will continue to refine impurity and loss estimates and impurity limits on fuels by incorporating results from ongoing R&D. And we will begin work on an enhanced nuclear material management model to allow us to continue to improve our overall system understanding of the trade-offs between separations, fuel fabrication, waste forms, waste disposition, SNM losses, reactor performance, and proliferation resistance. In the future, we can also better understand how used fuel and other forms of remote-handled SNM can be better integrated into an overall nuclear material management program that will evolve for the DOE complex via Order 410.2 (DOE 2009).

DOE Patents (OSTI)

A magnetically insulated transmission line oscillator employs self-generated magnetic fields to generate microwave energy. An anode of the oscillator includes slow-wave structures which are formed of a plurality of thin conductive vanes defining cavities therebetween, and a gap is formed between the anode and a cathode of the oscillator. In response to a pulsed voltage applied to the anode and cathode, self-generated magnetic fields arfe produced in a cross-field orientation with respect to the orientation of the electric field between the anode and the cathode. The cross-field magnetic fields insulate the flow of electrons in the gap and confine the flow of electrons within the gap.

Power Line Calculator for DOS  

Science Conference Proceedings (OSTI)

The Power Line Calculator (PLC) for DOS, version 1.0, is a program that describes the electrical characteristics of a transmission or distribution system given user-defined input. This input may consist of a combination of operating currents and phases, symmetric components, power factor, and real or reactive power. The program also allows the user to designate whether currents are present on the system neutral or in the ground. The PLC assumes that any value entered by the user remains fixed (e.g., phase current, power factor), and for underdetermined systems, basic default assumptions are incorporated: the power factor is held at or near 1.0, the net phase current is kept at or near zero, and the phase conductor currents are kept balanced. The program operates under PC/MS-DOS version 3.3 or later, and the output is available in both tabular and graphic formats.

An anode of the oscillator includes slow-wave structures which are formed of a plurality of thin conductive vanes defining cavities therebetween, and a gap is formed between the anode and a cathode of the oscillator. In response to a pulsed voltage applied to the anode and cathode, self-generated magnetic fields are produced in a cross-field orientation with respect to the orientation of the electric field between the anode and the cathode. The cross-field magnetic fields insulate the flow of electrons in the gap and confine the flow of electrons within the gap. 11 figs.

Germ-line Allele  

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

Germ-line Allele Germ-line Allele Name: Rachel Location: N/A Country: N/A Date: N/A Question: Can you please explain a "germ-line allele" to me! It is very important for a research paper I am writing about breast cancer. Replies: Mutations in genes are only able to be passed to the offspring if they are found in gametes (egg, sperm) mutations that occur in body cells other than gametes are usually not important because the cells can be replaced and they die eventually. The only way a characteristic can be passed to the offspring is through the eggs and sperm, so if there is a mutation in one these cells, the offspring can inherit the mutation. So a germ-line cell is a gamete. And a germ line allele is a version of the trait that is passed to the offspring through the germ line cell (or gamete).

On the reliability of mass-loss-rate estimates for AGB stars  

E-Print Network (OSTI)

In the recent literature there has been some doubt as to the reliability of CO multi-transitional line observations as a mass-loss-rate estimator for AGB stars. Mass-loss rates for 10 intermediate- to high-mass-loss-rate AGB stars are derived using a detailed non-LTE, non-local radiative transfer code based on the Monte-Carlo method to model the CO radio line intensities. The circumstellar envelopes are assumed to be spherically symmetric and formed by constant mass-loss rates. The energy balance is solved self-consistently and the effects of dust on the radiation field and thermal balance are included. An independent estimate of the mass-loss rate is also obtained from the combination of dust radiative transfer modelling with a dynamical model of the gas and dust particles. We find that the CO radio line intensities and shapes are successfully reproduced for the majority of our objects assuming a constant mass-loss rate. Moreover, the CO line intensities are only weakly dependent on the adopted micro-turbulent velocity, in contrast to recent claims in the literature. The two methods used in the present work to derive mass-loss-rates are consistent within a factor of ~3 for intermediate- to high-mass-loss-rate objects, indicating that this is a lower limit to the uncertainty in present mass-loss-rate estimates. We find a tentative trend with chemistry. Mass-loss rates from the dust/dynamical model are systematically higher than those from the CO model for the carbon stars and vice versa for the M-type stars. This could be ascribed to a discrepancy in the adopted CO/H_2-abundance ratio, but we caution that the sample is small and systematic errors cannot be excluded.

Sound energy loss during sonolysis  

Science Conference Proceedings (OSTI)

This paper gives an analysis of sound energy losses due to sonolysis — dissociation of the part of water molecules to radicals H? and ?OH. The value of the energy loss can be evaluated by using the concentration of hydrogen peroxide which appears in the water as a result of cross?recombination of radicals ?OH+?OH=H2O2. Data previously obtained by different authors were used for the present analysis. Data for fresh water and also for water with dissolved gases were considered. Data covered a sound frequency range from 1.5 kHz to 2 MHz and sound pressure amplitudes 0.6–2.5 atm for normal static pressure and a water temperature of 20?°C. It is shown that the rate of increasing hydrogen peroxide concentration is proportional to the intensity of sound. The rate is also propor? tional to the concentration of dissolved oxygen and argon in water while other gases (hydrogen

Mechanical model for ductility loss  

Science Conference Proceedings (OSTI)

A mechanical model was constructed to probe into the mechanism of ductility loss. Fracture criterion based on critical localized deformation was undertaken. Two microstructure variables were considered in the model. Namely, the strength ratio of grain boundary affected area to the matrix, ..cap omega.., and the linear fraction, x, of grain boundary affected area. A parametrical study was carried out. The study shows that the ductility is very sensitive to those microstructure parameters. The functional dependence of ductility to temperature as well as strain-rate, suggested by the model, is demonstrated to be consistent with the observation.

Transmission line capital costs  

Science Conference Proceedings (OSTI)

The displacement or deferral of conventional AC transmission line installation is a key benefit associated with several technologies being developed with the support of the U.S. Department of Energy`s Office of Energy Management (OEM). Previous benefits assessments conducted within OEM have been based on significantly different assumptions for the average cost per mile of AC transmission line. In response to this uncertainty, an investigation of transmission line capital cost data was initiated. The objective of this study was to develop a database for preparing preliminary estimates of transmission line costs. An extensive search of potential data sources identified databases maintained by the Bonneville Power Administration (BPA) and the Western Area Power Administration (WAPA) as superior sources of transmission line cost data. The BPA and WAPA data were adjusted to a common basis and combined together. The composite database covers voltage levels from 13.8 to 765 W, with cost estimates for a given voltage level varying depending on conductor size, tower material type, tower frame type, and number of circuits. Reported transmission line costs vary significantly, even for a given voltage level. This can usually be explained by variation in the design factors noted above and variation in environmental and land (right-of-way) costs, which are extremely site-specific. Cost estimates prepared from the composite database were compared to cost data collected by the Federal Energy Regulatory Commission (FERC) for investor-owned utilities from across the United States. The comparison was hampered because the only design specifications included with the FERC data were voltage level and line length. Working within this limitation, the FERC data were not found to differ significantly from the composite database. Therefore, the composite database was judged to be a reasonable proxy for estimating national average costs.

The tractability of CSP classes defined by forbidden patterns  

E-Print Network (OSTI)

The constraint satisfaction problem (CSP) is a general problem central to computer science and artificial intelligence. Although the CSP is NP-hard in general, considerable effort has been spent on identifying tractable subclasses. The main two approaches consider structural properties (restrictions on the hypergraph of constraint scopes) and relational properties (restrictions on the language of constraint relations). Recently, some authors have considered hybrid properties that restrict the constraint hypergraph and the relations simultaneously. Our key contribution is the novel concept of a CSP pattern and classes of problems defined by forbidden patterns (which can be viewed as forbidding generic subproblems). We describe the theoretical framework which can be used to reason about classes of problems defined by forbidden patterns. We show that this framework generalises relational properties and allows us to capture known hybrid tractable classes. Although we are not close to obtaining a dichotomy concern...

An investigation was made of Cosmotron intensity versus time through the entire time interval from the beginning of injection to the completion of r-f capture. The induction electrode signal was used for the instartaneous measurement of beam intensity. Oscilloscope displays of the signal were photographed and traced. Base lines were filled in on the tracings and the area of the pulses measured with a polar pianimeter. It was found that the relation losses of beam intensity increase with injection intensity (total injected charge), and that most of the losses take place in the time interval between the end of injection and the completion of the first synchrotron oscillation.

Defining cell culture conditions to improve human norovirus infectivity assays  

SciTech Connect

Significant difficulties remain for determining whether human noroviruses (hNoV) recovered from water, food, and environmental samples are infectious. Three-dimensional tissue culture of human intestinal cells has shown promise in developing an infectivity assay, but reproducibility, even within a single laboratory, remains problematic. From the literature and our observations, we hypothesized that the common factors that leads to more reproducible hNoV infectivity in vitro requires that the cell line be 1) of human gastrointestinal origin, 2) expresses apical microvilli, and 3) be a positive secretor cell line. The C2BBe1 cell line, which is a brush-border producing clone of Caco-2, meets these three criteria. When challenged with Genogroup II viruses, we observed a 2 Log10 increase in viral RNA titer. A passage experiment with GII viruses showed evidence of the ability to propagate hNoV by both reverse transcription quantitative PCR (qRT-PCR) and microscopy. Using 3-D C2BBe1 cells improves reproducibility of the infectivity assay for hNoV, but the assay can still be variable. Two sources of variability include the cells themselves (mixed phenotypes of small and large intestine) and initial titer measurements using quantitative reverse transcription PCR (qRT-PCR) that measures all RNA vs. plaque assays that measure infectious virus.

In this work we give a concise definition of information loss from a system-theoretic point of view. Based on this definition, we analyze the information loss in static input-output systems subject to a continuous-valued input. For a certain class of multiple-input, multiple-output systems the information loss is quantified. An interpretation of this loss is accompanied by upper bounds which are simple to evaluate. Finally, a class of systems is identified for which the information loss is necessarily infinite. Quantizers and limiters are shown to belong to this class.

DOE Green Energy (OSTI)

A cryopumping module using metallic surfaces at liquid helium temperature for condensation of hydrogen and deuterium gas has been constructed. This pump, a prototype of four units which will provide pumping for the Livermore 200 kV test stand, will be used to verify the concept and establish engineering parameters. Upon completion of engineering tests and evaluation the pump will be installed in an operating beam line. The design point pumping capacity is 80,000 liters per second for hydrogen and deuterium at 10$sup -4$ torr based on sticking coefficients of 0.15 and 0.25, respectively. Both the liquid helium temperature pumping surface and the liquid nitrogen temperature radiation shields are constructed of quilted double wall cylindrical shells. The pumping shell dimensions are 1.5 meters dia. x 0.6 meters long. Cryogen circulation is convection current driven in both cases. Liquid helium is supplied from an overhead Dewar through bayonet coupling. In the 200 kV beam line, pumping modules will be supplied via transfer lines from a central Dewar. Voltage standoff will be accomplished in the transfer lines. (auth)

Independent Signs of Lower Mass-Loss Rates for O-Type Stars  

E-Print Network (OSTI)

I discuss observational evidence -- independent of the direct spectral diagnostics of stellar winds themselves -- suggesting that mass-loss rates for O stars need to be revised downward by roughly a factor of three or more, in line with recent observed mass-loss rates for clumped winds. These independent constraints include the large observed mass-loss rates in LBV eruptions, the large masses of evolved massive stars like LBVs and WNH stars, WR stars in lower metallicity environments, observed rotation rates of massive stars at different metallicity, supernovae that seem to defy expectations of high mass-loss rates in stellar evolution, and other clues. I pay particular attention to the role of feedback that would result from higher mass-loss rates, driving the star to the Eddington limit too particular attention to the role of feedback that would result from higher mass-loss rates, driving the star to the Eddington limit too soon, and therefore making higher rates appear highly implausible. Some of these arguments by themselves may have more than one interpretation, but together they paint a consistent picture that steady line-driven winds of O-type stars have lower mass-loss rates and are significantly clumped.

EIA - International Energy Outlook 2008-Defining the Limits of Oil  

Gasoline and Diesel Fuel Update (EIA)

Defining the Limits of Oil Production Defining the Limits of Oil Production Preparing mid-term projections of oil production requires an assessment of the availability of resources to meet production requirements, particularly for the later years of the 2005-2030 projection period in IEO2008. The IEO2008 oil production projections were limited by three factors: the estimated quantity of petroleum in place before production begins (“petroleum-initially-in-place” or IIP), the percentage of IIP extracted over the life of a field (ultimate recovery factor), and the amount of oil that can be produced from a field in a single year as a function of its remaining reserves. Total IIP resources are the quantities of petroleum—both conventional and unconventional—estimated to exist originally in naturally occurring accumulations.a IIP resources are those quantities of petroleum which are estimated, on a given date, to be contained in known accumulations, plus those quantities already produced, as well as those estimated quantities in accumulations yet to be discovered. The estimate of IIP resources includes both recoverable and unrecoverable resources.

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

Defining How Botulinum Toxin Binds to Defining How Botulinum Toxin Binds to the Synaptotagmin Receptor and Creating Improved Therapeutics to Block Toxicity Botulinum neurotoxin (BoNT), the most potent toxin known, induces a potentially fatal paralytic condition known as "botulism". Botulism can occur when toxin-producing bacteria infect wounds (wound botulism) or the intestinal tract (infant/intestinal botulism), or following the ingestion of contaminated food in which toxin has been produced (food-borne botulism). In the USA, infant botulism represents the most common manifestation of the disease, where its prevalence has led to speculation of a link to sudden infant death syndrome. BoNTs are subdivided into seven distinct serotypes (types A through G), and an increasingly large number of subtypes continue to be identified within each serotype, highlighting the need to produce broad-spectrum therapeutics. BoNT variants are an important biochemical set of tools for understanding nerve function, and important therapeutic agents in current clinical use to provide relief to patients with a wide spectrum of neurological disorders.

Nonlinear magnetoinductive transmission lines  

E-Print Network (OSTI)

Power transmission in one-dimensional nonlinear magnetic metamaterials driven at one end is investigated numerically and analytically in a wide frequency range. The nonlinear magnetic metamaterials are composed of varactor-loaded split-ring resonators which are coupled magnetically through their mutual inductances, forming thus a magnetoiductive transmission line. In the linear limit, significant power transmission along the array only appears for frequencies inside the linear magnetoinductive wave band. We present analytical, closed form solutions for the magnetoinductive waves transmitting the power in this regime, and their discrete frequency dispersion. When nonlinearity is important, more frequency bands with significant power transmission along the array may appear. In the equivalent circuit picture, the nonlinear magnetoiductive transmission line driven at one end by a relatively weak electromotive force, can be modeled by coupled resistive-inductive-capacitive (RLC) circuits with voltage-dependent cap...

Vehicle Technologies Office: Parasitic Loss Reduction  

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

Parasitic Loss Reduction Parasitic Loss Reduction Heavy vehicles lose a tremendous amount of energy to wind resistance and drag, braking, and rolling resistance. Such non-engine losses can account for an approximate 45% decrease in efficiency. Other sources of energy loss include: friction and wear in the power train, thermal (heat) loads, operation of auxiliary loads (air conditioning, heaters, refrigeration, etc.), and engine idling. The parasitic loss activity identifies methodologies that may reduce energy losses, and tests those in the laboratory. Promising technologies are then prototyped and tested onboard heavy vehicles. Once validated, technologies must be tested on-road to obtain durability, reliability, and life-cycle cost data for the developmental component and/or design strategy.

765kV Transmission line Voltage gradient  

E-Print Network (OSTI)

Corona ring Transmission lines Nowadays, due to the ever increasing energy consumption and power supply optimization, it is required to construct new power plants, substations and transmission lines. In Iran, also, because of increasing demand for electrical energy, for a significant power loss reduction in power transmission over long distances, and to construct high transmission lines that lead to reduction in the economic costs of transmission lines, the transmission lines must be considered at extra high voltage (EHV) levels. These EHV levels should be compared with the low voltage levels in order to extract the benefits. Therefore, in this paper, a review has been conducted on the types of 765 kV transmission lines used in different countries and a comparison between them and the low voltage levels have been performed. Accordingly, the advantages of EHV transmission lines are summarized. Finally, designing a line of 765 kV single-circuit with 6 conductors per bundle based on existing standards is presented.

Heat loss from an open cavity  

DOE Green Energy (OSTI)

Cavity type receivers are used extensively in concentrating solar thermal energy collecting systems. The Solar Total Energy Project (STEP) in Shenandoah, Georgia is a large scale field test for the collection of solar thermal energy. The STEP experiment consists of a large field array of solar collectors used to supplement the process steam, cooling and other electrical power requirements of an adjacent knitwear manufacturing facility. The purpose of the tests, conducted for this study, was to isolate and quantify the radiative, conductive, and convective components of total heat loss, and to determine the effects of operating temperature, receiver angle, and aperture size on cavity heat loss. An analytical model for radiative heat loss was developed and compared with two other methods used to determine radiative heat loss. A proposed convective heat loss correlation, including effects of aperture size, receiver operating temperature, and receiver angle is presented. The resulting data is a source to evaluate the STEP measurements.

Formation of Well-defined Nanocolumns by Ion Tracking Lithography  

SciTech Connect

Low dimensional systems on the nanometer scale afford a wealth of interesting possibilities including highly anisotropic behavior and quantum effects. Nanocolumns permit electrical and mechanical contact, yet benefit from two confined dimensions. This confinement leads to new optical, mechanical, electrical, chemical, and magnetic properties. We construct nanocolumn arrays with precise definition and independent control of diameter, length, orientation, areal density and composition so that geometry can be directly correlated to the quantum physical property of interest. The precision and control are products of the fabrication technique that we use. The process starts with an ion of sufficient energy to ''track'' a dielectric such as a film applied uniformly onto a substrate. The energy loss of the ion alters chemical bonding in the dielectric along the ion's straight trajectory. A suitable etchant quickly dissolves the latent tracks leaving high aspect ratio holes of small diameter ({approx}10nm) penetrating a film as thick as several microns. These small holes are interesting and useful in their own right and can be made to any desired size by continuing the etching process. Moreover, they serve as molds for electrochemical filling. After this electro-deposition, the mold material can be removed leaving the columns firmly attached to the substrate at the desired orientation. A variety of structures can be envisioned with these techniques. As examples, we have created arrays of Ni and of Pt nanocolumns ({approx}60 nm diameter and {approx}600 nm long) oriented perpendicular to the substrate. The high aspect ratio and small diameter of the columns enables easy observation of quantum behavior, namely efficient electron field emission and Fowler Nordheim behavior.

Chemisorption of Aromatic Compounds on Well-Defined Palladium Surfaces: Studies by Electron Spectroscopy and Electrochemistry  

E-Print Network (OSTI)

The chemisorption of aromatic compounds, derivatized with different functional groups, on well-defined Pd(111) surfaces was studied by a combination of Auger electron spectroscopy (AES), low energy electron diffraction (LEED), high resolution electron energy loss spectroscopy (HREELS), and electrochemistry (EC). The results of this work led to the following trends and conclusions: (a) At low concentrations, 2,5-dihydroxythiophenol (DHT) chemisorbs on a Pd surface through both diphenolic ring and thiol group. At high concentrations, it chemisorbs only through the thiol group. (b) There is extensive intermolecular attraction between the co-adsorbed thiolated quinone and thiolated hydroquinone molecules. The interaction occurs through the Pd substrate and not through space. (c) The chemisorption properties of Nheteroaromatic compounds are pH-dependent. When the nitrogen heteroatom is protonated, it becomes very weakly surface-active. When the nitrogen heteroatom is deprotonated, surface activity stronger than the diphenolic ring is exhibited. (d) On a palladium surface, the binding strengths of ligands increase in the order: phenyl ring < quinonoid ring, < N-heteroatom < I < -SH.

Improving the thermal performance of a trough plant will lower the LCOE: (1) Improve mirror alignment using the TOPCAT system - Current - increase optical intercept of existing trough solar power plants, Future - allows larger apertures with same receiver size in new trough solar power plants, and Increased concentration ratios/collection efficiencies & economies of scale; and (2) Improve tracking using a closed loop tracking system - Open loop tracking currently used own experience and from industry show need for a improved method. Performance testing of a Trough module and/or receiver on the rotating platform: (1) Installed costs of a trough plant are high. A significant portion of this is the material and assembly cost of the trough module. These costs need to be reduced without sacrificing performance; and (2) New receiver coatings with lower heat loss and higher absorbtivity. TOPCAT system is an optical evaluation tool for parabolic trough solar collectors. Aspects of the TOPCAT system are: (1) Practical, rapid, and cost effective; (2) Inherently aligns mirrors to the receiver of an entire solar collector array (SCA); (3) Can be used for existing installations -no equivalent tool exits; (4) Can be used during production; (5) Currently can be used on LS-2 or LS-3 configurations, but can be easily modified for any configuration; and (6)Generally, one time use.

We show how the multiloop bosonic Green function of closed string theory reduces to the world-line Green function as defined by Schmidt and Schubert in the limit where the string world-sheet degenerates into a $\\Phi^3$ particle diagram. To obtain this correspondence we have to make an appropriate choice of the local coordinates defined on the degenerate string world sheet. We also present a set of simple rules that specify, in the explicit setting of the Schottky parametrization, which is the corner of moduli space corresponding to a given multiloop $\\Phi^3$ diagram.

Analytic Loss Distributional Approach Model for Operational Risk from the alpha-Stable Doubly Stochastic Compound Processes and Implications for Capital Allocation  

E-Print Network (OSTI)

Under the Basel II standards, the Operational Risk (OpRisk) advanced measurement approach is not prescriptive regarding the class of statistical model utilised to undertake capital estimation. It has however become well accepted to utlise a Loss Distributional Approach (LDA) paradigm to model the individual OpRisk loss process corresponding to the Basel II Business line/event type. In this paper we derive a novel class of doubly stochastic alpha-stable family LDA models. These models provide the ability to capture the heavy tailed loss process typical of OpRisk whilst also providing analytic expressions for the compound process annual loss density and distributions as well as the aggregated compound process annual loss models. In particular we develop models of the annual loss process in two scenarios. The first scenario considers the loss process with a stochastic intensity parameter, resulting in an inhomogeneous compound Poisson processes annually. The resulting arrival process of losses under such a model...

We introduce approximate query techniques for searching and analyzing two-dimensional data sets such as line or scatter plots. Our techniques allow users to explore a dataset by defining QueryLines: soft constraints and preferences for selecting and sorting a subset of the data. By using both preferences and soft constraints for query composition, we allow greater flexibility and expressiveness than previous visual query systems. When the user over-constrains a query, for example, a system using approximate techniques can display ¨near misses¨to enable users to quickly and continuously refine queries.

ANALYSIS OF DISTRIBUTION FEEDER LOSSES DUE TO ADDITION OF DISTRIBUTED PHOTOVOLTAIC GENERATORS  

SciTech Connect

Distributed generators (DG) are small scale power supplying sources owned by customers or utilities and scattered throughout the power system distribution network. Distributed generation can be both renewable and non-renewable. Addition of distributed generation is primarily to increase feeder capacity and to provide peak load reduction. However, this addition comes with several impacts on the distribution feeder. Several studies have shown that addition of DG leads to reduction of feeder loss. However, most of these studies have considered lumped load and distributed load models to analyze the effects on system losses, where the dynamic variation of load due to seasonal changes is ignored. It is very important for utilities to minimize the losses under all scenarios to decrease revenue losses, promote efficient asset utilization, and therefore, increase feeder capacity. This paper will investigate an IEEE 13-node feeder populated with photovoltaic generators on detailed residential houses with water heater, Heating Ventilation and Air conditioning (HVAC) units, lights, and other plug and convenience loads. An analysis of losses for different power system components, such as transformers, underground and overhead lines, and triplex lines, will be performed. The analysis will utilize different seasons and different solar penetration levels (15%, 30%).

SciTech Connect

The Power Line Calculator (PLC) for Windows [trademark], version 1.0, is a program that describes the electrical characteristics of a transmission or distribution system given user-defined input. This input may consist of a combination of operating currents and phases, symmetric components, power factor, and real or reactive power. The program also allows the user to designate whether currents are present on the system neutral or in the ground. The PLC assumes that any value entered by the user remains fixed (e.g., phase current, power factor), and for underdetermined systems, basic default assumptions are incorporated: the power factor is held at or near 1.0, the net phase current is kept at or near zero, and the phase conductor currents are kept balanced. The program operates through a graphical user interface provided by Microsoft[reg sign] Windows [trademark] (version 3.1 or higher required), and the output is available in both tabular and graphic formats.

The Fortran 90 RIAPMTQ/IMPACT code package is a pair of linked beam-dynamics simulation codes that have been developed for end-to-end computer simulations of multiple-charge-state heavy-ion linacs for future exotic-beam facilities. These codes have multiple charge-state capability, and include space-charge forces. The simulations can extend from the low-energy beam-transport line after an ECR ion source to the end of the linac. The work has been performed by a collaboration including LANL, LBNL, ANL, and MSU. The code RIAPMTQ simulates the linac front-end beam dynamics including the LEBT, RFQ, and MEBT. The code IMPACT simulates the beam dynamics of the main superconducting linac. The codes have been benchmarked for rms beam properties against previously existing codes at ANL and MSU. The codes allow high-statistics runs on parallel supercomputing platforms, particularly at NERSC at LBNL, for studies of beam losses. The codes also run on desktop PC computers for low-statistics work. The code package is described in more detail in a recent publication [1] in the Proceedings of PAC07 (2007 US Particle Accelerator Conference). In this report we describe the main activities for the FY07 beam-loss studies project using this code package.

Interactive Transmission Line Computer Program for Undergraduate Teaching  

E-Print Network (OSTI)

Distributed-circuit analysis using transmission lines is a standard topic in undergraduate education in electrical engineering and computer engineering. This paper presents a simple menu-driven program that students can use to explore the behavior of transmission line circuits, and as a computational laboratory for verifying their solutions to homework problems. At the introductory level the program demonstrates traveling waves and standing waves. Smith-chart calculations of impedance and reflection coefficient can be associated with the standing-wave pattern on the transmission line. A branching circuit can be solved, including impedance matching with a quarter-wave transformer. At the intermediate level, students can use the program to test their designs for two- and three-step Chebyshev transformers, and for impedance matching using single, double and triple-stub circuits. The program makes easy the calculation of the bandwidth of a design by displaying the return loss or transmission loss as a function of frequency. Low-pass and bandstop filters can be solved. The program encourages students to explore the behavior of the voltages and currents on the lines as the frequency is changed to gain insight into the operation of transformers, matching schemes and filters.

The energy injection and losses in the Monte Carlo simulations of a diffusive shock  

E-Print Network (OSTI)

Although diffusive shock acceleration (DSA) could be simulated by some well-established models, the assumption of the injection rate from the thermal particles to the superthermal population is still a contentious problem. But in the self-consistent Monte Carlo simulations, because of the prescribed scattering law instead of the assumption of the injected function, hence particle injection rate is intrinsically defined by the prescribed scattering law. We expect to examine the correlation of the energy injection with the prescribed multiple scattering angular distributions. According to the Rankine-Hugoniot conditions, the energy injection and the losses in the simulation system can directly decide the shock energy spectrum slope. By the simulations performed with multiple scattering law in the dynamical Monte Carlo model, the energy injection and energy loss functions are obtained. As results, the case applying anisotropic scattering law produce a small energy injection and large energy losses leading to a s...

Atom-molecule conversion with particle losses  

E-Print Network (OSTI)

Based on the mean-field approximation and the phase space analysis, we study the dynamics of an atom-molecule conversion system subject to particle loss. Starting from the many-body dynamics described by a master equation, an effective nonlinear Schr\\"odinger equation is introduced. The classical phase space is then specified and classified by fixed points. The boundary, which separate different dynamical regimes have been calculated and discussed. The effect of particle loss on the conversion efficiency and the self-trapping is explored.

AC Loss Measurements with a Cryocooled Sample  

SciTech Connect

A new cryostat cooled by a closed-cycle Cryomech GB-37 cryocooler for superconductor measurements at temperatures down to 20 K is described. The sample is conductively coupled to the cold stage so as to minimize vibration and thermal stresses. AC losses have been measured calorimetrically in several HTSC coils that have been wound to simulate sub-scale transformer winding pairs. Stable temperatures down to 20 K were reached on these coils, allowing measurements at practical levels of ac current and I{sub c}. By using short ac current pulses, losses on individual turns could be resolved. Results are reported mainly to showcase the apparatus, measurement procedure and analytical approach.

Chemistry and line emission from evolving Herbig Ae disks  

E-Print Network (OSTI)

Aims: To calculate chemistry and gas temperature of evolving protoplanetary disks with decreasing mass or dust settling, and to explore the sensitivity of gas-phase tracers. Methods: The density and dust temperature profiles for a range of models of flaring and self-shadowed disks around a typical Herbig Ae star are used together with 2-dimensional ultraviolet (UV) radiative transfer to calculate the chemistry and gas temperature. In each model the line profiles and intensities for the fine structure lines of [O I], [C II] and [C I] and the pure rotational lines of CO, CN, HCN and HCO+ are determined. Results: The chemistry shows a strong correlation with disk mass. Molecules that are easily dissociated, like HCN, require high densities and large extinctions before they can become abundant. The products of photodissociation, like CN and C2H, become abundant in models with lower masses. Dust settling mainly affects the gas temperature, and thus high temperature tracers like the O and C+ fine structure lines. The carbon chemistry is found to be very sensitive to the adopted PAH abundance. The line ratios CO/13CO, CO/HCO+ and [O I] 63 um/146 um can be used to distinguish between disks where dust growth and settling takes place, and disks that undergo overall mass loss.

Economics of heat loss for power cables  

SciTech Connect

Energy losses occur in power cables which cause a rise in the conductor temperature. A trend toward higher allowable conductor temperatures has increased the energy losses during operation. At the same time, the costs of the energy has increased dramatically. With a given installation and load, energy costs vary inversely with the conductor size. However, initial costs vary directly with the conductor size. This relationship can be utilized to select a conductor size which minimizes the sum of the initial costs an the energy costs. This paper reviews present value techniques and identifies the level of energy costs in some particular installation configurations. An analysis is made of the marginal costs and savings available by changing the size of the conductor in a cable circuit.

Information Loss in Black Hole Evaporation  

E-Print Network (OSTI)

Parikh-Wilczek tunnelling framework is investigated again. We argue that Parikh-Wilczek's treatment, which satisfies the first law of black hole thermodynamics and consists with an underlying unitary theory, is only suitable for a reversible process. Because of the negative heat capacity, an evaporating black hole is a highly unstable system. That is, the factual emission process is irreversible, the unitary theory will not be satisfied and the information loss is possible.

Sirius A: turbulence or mass loss?  

E-Print Network (OSTI)

Context. Abundance anomalies observed in a fraction of A and B stars of both Pop I and II are apparently related to internal particle transport. Aims. Using available constraints from Sirius A, we wish to determine how well evolutionary models including atomic diffusion can explain observed abundance anomalies when either turbulence or mass loss is used as the main competitor to atomic diffusion. Methods. Complete stellar evolution models, including the effects of atomic diffusion and radiative accelerations, have been computed from the zero age main-sequence of 2.1M\\odot stars for metallicities of Z0 = 0.01 \\pm 0.001 and shown to agree with the observed parameters of Sirius A. Surface abundances were predicted for three values of the mass loss rate and for four values of the mixed surface zone. Results. A mixed mass of ~ 10^-6 M\\odot or a mass loss rate of 10^-13 M\\odot/yr were determined through comparison with observations. Of the 17 abundances determined observationally which are included in our calculati...

DIVERSITY OF LUMINOUS SUPERNOVAE FROM NON-STEADY MASS LOSS  

Science Conference Proceedings (OSTI)

We show that the diversity in the density slope of the dense wind due to non-steady mass loss can be one way to explain the spectral diversity of Type II luminous supernovae (LSNe). The interaction of SN ejecta and wind surrounding it is considered to be a power source to illuminate LSNe because many LSNe show the wind signature in their spectra (Type IIn LSNe). However, there also exist LSNe without the spectral features caused by the wind (Type IIL LSNe). We show that, even if LSNe are illuminated by the interaction, it is possible that they do not show the narrow spectra from the wind if we take into account the non-steady mass loss of their progenitors. When the shock breakout takes place in a dense wind with the density structure {rho}{proportional_to}r{sup -w}, the ratio of the diffusion timescale in the optically thick region of the wind (t{sub d} ) and the shock propagation timescale of the entire wind after the shock breakout (t{sub s} ) strongly depends on w. For the case w {approx}< 1, both timescales are comparable (t{sub d} /t{sub s} {approx_equal} 1) and t{sub d} /t{sub s} gets smaller as w gets larger. For the case t{sub d} /t{sub s} {approx_equal} 1, the shock goes through the entire wind just after the light-curve (LC) peak, and narrow spectral lines from the wind cannot be observed after the LC peak (Type IIL LSNe). If t{sub d} /t{sub s} is much smaller, the shock wave continues to propagate in the wind after the LC peak, and unshocked wind remains (Type IIn LSNe). This difference can be obtained only through careful treatment of the shock breakout condition in a dense wind. The lack of narrow Lorentzian line profiles in Type IIL LSNe before the LC peak can also be explained by the difference in the density slope. Furthermore, we apply our model to Type IIn LSN 2006gy and Type IIL LSN 2008es and find that our model is consistent with the observations.

Experimental performance evaluation of line-focus sun trackers  

DOE Green Energy (OSTI)

Two sun trackers have been tested for tracking accuracy on an sun tracker. Both performed well during the entire test period. Their tracking performance as a function of insolation level was established, and their overall tracking accuracy (rms tracking error) was calculated. Both the flux-line and the shadowband tracker were found to have an effective rms error of about 1 milliradian. This information was used to determine the impact that the two trackers have on the annual energy performance of typical parabolic trough concentrating collectors. One milliradian rms tracking errors were found to result in negligibly small annual performance losses.

Optimal detection of losses by thermal probes  

E-Print Network (OSTI)

We consider the discrimination of lossy bosonic channels and focus to the case when one of the values for the loss parameter is zero, i.e., we address the detection of a possible loss against the alternative hypothesis of an ideal lossless channel. This discrimination is performed by inputting one-mode or two-mode squeezed thermal states with fixed total energy. By optimizing over this class of states, we find that the optimal inputs are pure, thus corresponding to single- and two-mode squeezed vacuum states. In particular, we show that for any value of the damping rate smaller than a critical value there is a threshold on the energy that makes the two-mode squeezed vacuum state more convenient than the corresponding single-mode state, whereas for damping larger than this critical value two-mode squeezed vacua are always better. We then consider the discrimination in realistic conditions, where it is unlikely to have pure squeezing. Thus by fixing both input energy and squeezing, we show that two-mode squeezed thermal states are always better than their single- mode counterpart when all the thermal photons are directed into the dissipative channel. Besides, this result also holds approximately for unbalanced distribution of the thermal photons. Finally, we also investigate the role of correlations in the improvement of detection. For fixed input squeezing (single-mode or two-mode), we find that the reduction of the quantum Chernoff bound is a monotone function of the two-mode entanglement as well as the quantum mutual information and the quantum discord. We thus verify that employing squeezing in the form of correlations (quantum or classical) is always a resource for loss detection whenever squeezed thermal states are taken as input.

Coiled transmission line pulse generators  

DOE Patents (OSTI)

Methods and apparatus are provided for fabricating and constructing solid dielectric "Coiled Transmission Line" pulse generators in radial or axial coiled geometries. The pour and cure fabrication process enables a wide variety of geometries and form factors. The volume between the conductors is filled with liquid blends of monomers, polymers, oligomers, and/or cross-linkers and dielectric powders; and then cured to form high field strength and high dielectric constant solid dielectric transmission lines that intrinsically produce ideal rectangular high voltage pulses when charged and switched into matched impedance loads. Voltage levels may be increased by Marx and/or Blumlein principles incorporating spark gap or, preferentially, solid state switches (such as optically triggered thyristors) which produce reliable, high repetition rate operation. Moreover, these Marxed pulse generators can be DC charged and do not require additional pulse forming circuitry, pulse forming lines, transformers, or an a high voltage spark gap output switch. The apparatus accommodates a wide range of voltages, impedances, pulse durations, pulse repetition rates, and duty cycles. The resulting mobile or flight platform friendly cylindrical geometric configuration is much more compact, light-weight, and robust than conventional linear geometries, or pulse generators constructed from conventional components. Installing additional circuitry may accommodate optional pulse shape improvements. The Coiled Transmission Lines can also be connected in parallel to decrease the impedance, or in series to increase the pulse length.

Status of wake and array loss research  

DOE Green Energy (OSTI)

In recent years, many projects have evaluated wind turbine wake effects and resultant array losses in both Europe and the United States. This paper examines the status of current knowledge about wake effects and array losses and suggests future research. Single-turbine wake characteristics have been studied extensively and are generally described well by existing theoretical models. Field measurements of wake effects in wind turbine arrays are largely limited to small arrays, with 2 to 4 rows of turbines. Few data have been published on wake effects within large arrays. Measurements of wake deficits downwind of large arrays that deficits are substantially larger and extend farther downwind than expected. Although array design models have been developed, these models have been tested and verified using only limited data from a few rows of wind turbines in complex terrain, whereas some of the largest arrays have more than 40 rows of wind turbines. Planned cooperative efforts with the wind industry will obtain existing data relevant to analyzing energy deficits within large arrays and identifying data sets for potential use in array model verification efforts. Future research being considered include a cooperative research experiment to obtain more definitive data on wake deficits and turbulence within and downwind of large arrays. 16 refs., 9 figs., 1 tab.

Parabolic Trough Receiver Heat Loss Testing (Poster)  

DOE Green Energy (OSTI)

Parabolic trough receivers, or heat collection elements (HCEs), absorb sunlight focused by the mirrors and transfer that thermal energy to a fluid flowing within them. Thje absorbing tube of these receivers typically operates around 400 C (752 F). HCE manufacturers prevent thermal loss from the absorbing tube to the environment by using sputtered selective Cermet coatings on the absorber and by surrounding the absorber with a glass-enclosed evacuated annulus. This work quantifies the heat loss of the Solel UVAC2 and Schott PTR70 HCEs. At 400 C, the HCEs perform similarly, losing about 400 W/m of HCE length. To put this in perspective, the incident beam radiation on a 5 m mirror aperture is about 4500 W/m, with about 75% of that energy ({approx} 3400 W/m) reaching the absorber surface. Of the 3400 W/m on the absorber, about 3000 W/m is absorbed into the working fluid while 400 W/m is lost to the environment.

An overview of MHD seawater thruster performance and loss mechanisms  

DOE Green Energy (OSTI)

Loss mechanisms affecting the performance of an MHD seawater thruster system have ben identified and discussed. Among those losses are the jet and nozzle losses, joule heating losses, surface potential and electro-chemical losses, frictional losses, and electrical end losses. Simple, but accurate, models have seen used to assess the relative and absolute magnitude of these losses and to investigate their influence on the overall thruster efficiency. A parametric study has been performed for a generic full size seawater vehicle propelled by an MHD thruster at different operating conditions. The results of this study confirm that higher efficiencies can be achieved at high magnetic field strengths (> 10 Tesla). Furthermore, the results indicate that higher efficiencies can be maintained over a wide range of cruising speeds (2--20 m/s or 4--40 knots) at higher magnetic fields (20 Tesla).

The results of this study confirm that higher efficiencies can be achieved at high magnetic field strengths (> 10 Tesla). Furthermore, the results indicate that higher efficiencies can be maintained over a wide range of cruising speeds (2--20 m/s or 4--40 knots) at higher magnetic fields (20 Tesla).

Beam line windows at LAMPF  

Science Conference Proceedings (OSTI)

The A-6 main beam-line window at LAMPF separates the vacuum of the main beam line from the isotope production station, proton irradiation ports, and the beam stop, which operate in air. This window must withstand the design beam current of 1 mA at 800 MeV for periods of at least 3000 hours without failure. The window is water cooled and must be strong enough to withstand the 2.1 MPa (300 psig) cooling water pressure, as well as beam-induced thermal stresses. Two designs have been used to meet these goals, a stepped-plate window and a hemispherical window, both made from a precipitation-hardened nickel base alloy, Alloy 718. Calculations of the temperatures and stresses in each of these windows are presented.

Quantum cryptographic system with reduced data loss  

DOE Patents (OSTI)

A secure method for distributing a random cryptographic key with reduced data loss. Traditional quantum key distribution systems employ similar probabilities for the different communication modes and thus reject at least half of the transmitted data. The invention substantially reduces the amount of discarded data (those that are encoded and decoded in different communication modes e.g. using different operators) in quantum key distribution without compromising security by using significantly different probabilities for the different communication modes. Data is separated into various sets according to the actual operators used in the encoding and decoding process and the error rate for each set is determined individually. The invention increases the key distribution rate of the BB84 key distribution scheme proposed by Bennett and Brassard in 1984. Using the invention, the key distribution rate increases with the number of quantum signals transmitted and can be doubled asymptotically.

Benchmark Models, Planes, Lines and Points for Future SUSY Searches at the LHC  

E-Print Network (OSTI)

We define benchmark models for SUSY searches at the LHC, including the CMSSM, NUHM, mGMSB, mAMSB, MM-AMSB and p19MSSM, as well as models with R-parity violation and the NMSSM. Within the parameter spaces of these models, we propose benchmark subspaces, including planes, lines and points along them. The planes may be useful for presenting results of the experimental searches in different SUSY scenarios, while the specific benchmark points may serve for more detailed detector performance tests and comparisons. We also describe algorithms for defining suitable benchmark points along the proposed lines in the parameter spaces, and we define a few benchmark points motivated by recent fits to existing experimental data.

The Oak Ridge Spallation Neutron Source (SNS) accelerator complex routinely delivers 1 MW of beam power to the spallation target. Due to this high beam power, understanding and minimizing the beam loss is an ongoing focus area of the accelerator physics program. In some areas of the accelerator facility the equipment parameters corresponding to the minimum loss are very different from the design parameters. In this presentation we will summarize the SNS beam loss measurements, the methods used to minimize the beam loss, and compare the design vs. the loss-minimized equipment parameters.

Energy harvesting: A battle against power losses  

E-Print Network (OSTI)

Is it possible, are indefinite operational life and wireless power grids possible? Maybe not for every application, but how about for micro-scale devices? The fact is in situ energy sources like MEMS vibrational and thermoelectric generators can potentially achieve these goals for small footprint systemin-package (SiP) solutions like bio-implantable devices and wireless sensor transceiver network nodes. The key objective is to scavenge sufficient energy from the environment to sustain the micro-power system indefinitely, or at least extend life to practical levels. The problem, however, is micro-scale harvesters can only generate low-to-moderate power, and the energy-storage and power-delivery processes of the system inherently consume a portion of that, which is why the various functions of a loading application must be power-moded, that is, multiplexed, duty-cycled, and turned off when not needed. Fortunately, low frequency ambient vibrations are relatively abundant, stable, and predictable, and tuned MEMS- and CMOS-compatible electrostatic harvesters, for instance, can generate moderate power levels [1], but only if they prevail over the power losses associated with energy storage and power delivery. The focus of this article is to therefore identify, quantify, and discuss the power-consuming mechanisms present in a harvester circuit. Harvesting energy

Detonation propagation in a high loss configuration  

SciTech Connect

This work presents an experimental study of detonation wave propagation in tubes with inner diameters (ID) comparable to the mixture cell size. Propane-oxygen mixtures were used in two test section tubes with inner diameters of 1.27 mm and 6.35 mm. For both test sections, the initial pressure of stoichiometric mixtures was varied to determine the effect on detonation propagation. For the 6.35 mm tube, the equivalence ratio {phi} (where the mixture was {phi} C{sub 3}H{sub 8} + 50{sub 2}) was also varied. Detonations were found to propagate in mixtures with cell sizes as large as five times the diameter of the tube. However, under these conditions, significant losses were observed, resulting in wave propagation velocities as slow as 40% of the CJ velocity U{sub CJ}. A review of relevant literature is presented, followed by experimental details and data. Observed velocity deficits are predicted using models that account for boundary layer growth inside detonation waves.

Process Refinements - Accounting for Motor-Fuel Losses  

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

Accounting for Motor-Fuel Losses Accounting for Motor-Fuel Losses Motor fuel may be lost by leakage from storage tanks, spillage, fire, or other means; in addition, measurement differences brought about by temperature or other conditions and meter faults can result in apparent losses. Because this lost fuel is neither consumed on the highway nor used for off-highway purposes, it presents a problem for determining the appropriate base for taxation. In the past, FHWA allowed States to report actual losses or a percentage loss, which was capped at 1%. Usage data for States that did not report losses were not adjusted by FHWA to account for losses. In addition, diesel losses were not considered significant and were not counted. During the reassessment meetings and in the Federal Register notice of August 17, 2000, it was recommended that actual diesel losses also be documented and reported. However, because diesel reporting accounts for actual on-highway fuel use, a reporting of diesel losses is unnecessary.

Shoreline erosion and wetland loss in Mississippi  

Science Conference Proceedings (OSTI)

Set within a geologic framework that includes Pleistocene and Holocene barrier complexes, estuarine bays, and fluvio-deltaic tidal wetlands, coastal Mississippi shares environmental problems of shoreline erosion and wetland loss with her neighboring Gulf Coast states. The mainland coast consists of several Pleistocene headlands and barrier complexes interspersed with the St. Louis Bay and Back Bay of Biloxi estuaries. Tidal wetlands are found in the protected bays and tributary streams, as well as in the Pleistocene/Holocene deltaic environments associated with the Escatawpa, Pascagoula, Pearl, and Mississippi fluvial systems. Four barrier islands, formed by erosion and modification of a late Pleistocene/Holocene beach ridge, lie 6 to 12 mi offshore. Historically, these islands with a combined length of 30 mi have both migrated westward in response to prevailing longshore currents and also transgressed across the shallow platform of Mississippi Sound. Wave erosion, both normal and storm-induced, has historically caused shoreline retreat on both the barrier islands and on the mainland. Erosion rates in excess of 30 ft/yr have been measured at the updrift ends of the barrier islands while accretion has characterized the downdrift ends. Net shoreline retreat rates of 6 ft/yr have been measured on the Gulf side of the islands, although the Sound side rates are nearly as high. Since the earliest accurate maps were made in 1848, Mississippi's barrier islands have experienced a 20% reduction in area, amounting to about 2,000 acres (800 ha). Mainland shoreline retreat rates are similarly high, except for along the more stable and now artificially nourished beaches of Harrison County. Erosion rates exceeding 10 ft/yr since 1940 have been noted at the Point aux Chenes headland and the Grand Batture Islands. These islands, which formerly sheltered valuable oyster grounds and protected fragile marshes, have been reduced to shoals over the last several decades.

Heating and cooling the Raft River geothermal transite pipe line  

SciTech Connect

A preliminary transient heat transfer analysis to aid in defining operating limits for the 4000-foot-long transite pipe line at the Raft River geothermal test site was completed. The heat transfer problem was to determine the time required to cool down the line from a 285/sup 0/F operating temperature to 50/sup 0/F and the time to heat up the line from 50/sup 0/F to 285/sup 0/F such that the temperature differential across the pipe wall will not exceed 25/sup 0/F. The pipe and the surrounding soil was modeled with a two-dimensional heat transfer computer code assuming constant convective heat transfer at the soil-atmosphere interface. The results are sensitive to the soil thermal conductivity used in the calculation and imply that measurement of soil thermal conductivity used in the calculation and imply that measurement of soil thermal properties should be made in order to refine the calculations. Also, the effect of variable convective heat transfer at the soil surface should be investigated. However, the results reported here indicate the order of magnitude to be expected for cool-down and heat-up times when operating the transite pipe at the stated condition.

Confidence in drip-line predictions of such models requires their comparison with new mass data for nuclides far from stability. We combine theory and experiment using results that are state of the art: the latest mass measurements from the Penning-trap spectrometer ISOLTRAP at CERN-ISOLDE are used to confront the predictions of the latest Skyrme-Hartree-Fock-Bogoliubov (HFB) microscopic mass models. In addition, we compare the new data to predictions of other types of mass models and the extrapolative behavior of the various models is analyzed to highlight topographical trends along the shores of the nuclear chart.

Gamma-Ray Burst Lines  

E-Print Network (OSTI)

The evidence for spectral features in gamma-ray bursts is summarized. As a guide for evaluating the evidence, the properties of gamma-ray detectors and the methods of analyzing gamma-ray spectra are reviewed. In the 1980's, observations indicated that absorption features below 100 keV were present in a large fraction of bright gamma-ray bursts. There were also reports of emission features around 400 keV. During the 1990's the situation has become much less clear. A small fraction of bursts observed with BATSE have statistically significant low-energy features, but the reality of the features is suspect because in several cases the data of the BATSE detectors appear to be inconsistent. Furthermore, most of the possible features appear in emission rather than the expected absorption. Analysis of data from other instruments has either not been finalized or has not detected lines.

On-line transformer monitoring  

Science Conference Proceedings (OSTI)

There are presently many different approaches to transformer monitoring, either on the market or under development. There are also, many different opinions about how on-line monitoring should be accomplished. On the one hand, efforts are being made to develop expert systems that monitor all transformer parameters and generate an estimate of overall transformer condition. On the other hand, a large number of transformer monitors, designed to monitor one or two specific parameters are already on the market. Another important factor to consider in choosing a monitor is who receives the information and how it is transmitted. The ultimate transformer monitor should feed into the supervisory control and data acquisition (Scada) system. This paper discusses the various aspects of this issue including asset protection, cost control, dissolved gases, pinpointing bad bushings and current transformers, hot spot measurement partial discharge, and water-in-oil measurements. 10 figs.

Science Conference Proceedings (OSTI)

This paper discusses the basis of a design for real time special nuclear material (SNM) loss detectors. The design utilizes process measurements and signal processing techniques to produce a timely estimate of material loss. A state estimator is employed as the primary signal processing algorithm. Material loss is indicated by changes in the states or process innovations (residuals). The design philosophy is discussed in the context of these changes.

Separation of magnetic field lines  

SciTech Connect

The field lines of magnetic fields that depend on three spatial coordinates are shown to have a fundamentally different behavior from those that depend on two coordinates. Unlike two-coordinate cases, a flux tube in a magnetic field that depends on all three spatial coordinates that has a circular cross section at one location along the tube characteristically has a highly distorted cross section at other locations. In an ideal evolution of a magnetic field, the current densities typically increase. Crudely stated, if the current densities increase by a factor {sigma}, the ratio of the long to the short distance across a cross section of a flux tube characteristically increases by e{sup 2{sigma}}, and the ratio of the longer distance to the initial radius increases as e{sup {sigma}}. Electron inertia prevents a plasma from isolating two magnetic field structures on a distance scale shorter than c/{omega}{sub pe}, which is about 10 cm in the solar corona, and reconnection must be triggered if {sigma} becomes sufficiently large. The radius of the sun, R{sub Circled-Dot-Operator }=7 Multiplication-Sign 10{sup 10}cm is about e{sup 23} times larger, so when {sigma} Greater-Than-Or-Equivalent-To 23, two lines separated by c/{omega}{sub pe} at one location can be separated by the full scale of any magnetic structures in the corona at another. The conditions for achieving a large exponentiation, {sigma}, are derived, and the importance of exponentiation is discussed.

Marine surveys aid gas line  

Science Conference Proceedings (OSTI)

Detailed marine surveys helped B.C. Hydro, a Canadian gas distribution utility, select the submarine route portion of the proposed Vancouver Island gas pipeline system. In 1984, after a series of government hearings, B.C. Hydro's route selection was adopted by the British Columbia Provincial Government. Vancouver Island is the last major population center in Western Canada not supplied with natural gas. In fact, studies of a gas pipeline to the island have been carried out periodically over the past 30 years. But until recently, all schemes have appeared unattractive because of a combination of technical, economic, and political factors. The proposed Vancouver Island project which is awaiting funding, consists of a dual 52.7-km marine transmission pipeline link from the mainland to the island. Diameter of this portion of line will be either 12 of 16-in. Also, part of the proposed system will be an 18.5-km line on the mainland, a 280-km transmission pipeline on the island, compression facilities, and distribution systems in the major population centers. Diameters for the land portions will vary between 6 and 24 in. For several months in late 1983 and early 1984, the project was the subject of public hearings held by the British Columbia Utilities Commission. This process was complicated when two companies applied to construct and operate the marine pipeline link to the island using completely different routes and techniques. In July 1984, the commission recommended to the Provincial Government that B.C. Hydro's proposal for the marine pipeline be accepted. It further recommended that an Energy Project Certificate for construction of the pipeline link to the island be awarded to B.C. Hydro. The recommendation was accepted by the Provincial Government and the project now awaits a funding agreement between the Federal and Provincial Governments.

Plasma end-loss studies on Scylla I-C  

SciTech Connect

The end-loss process in the collision dominated Scylla I-C plasma has been investigated with a local pressure sensitive diagnostic, integrated density measurement and axially arrayed diamagnetic loop probes. The development of a plasma loss orifice, well within the theta-pinch coil, has been identified. The magnitude of the observed orifice is found to be in excellent agreement with that predicted from collisional MHD theories. The axially flowing plasma is well confined until it flows through the loss orifice. After passing through the orifice, rapid axial expansion is observed. An indication of the existence of inward traveling rarefaction waves has been observed from the plasma midplane temperature data; an abrupt decrease in the plasma temperature at t approximately equal to 6.5 ..mu..s corresponds to the predicted time of arrival of rarefaction waves at the coil midplane. The plasma loss rate derived from the pressure data indicates an initial period (t < 4 ..mu..s) of rapid particle loss followed by a period (t > 4 ..mu..s) of gradual decay in the loss rate. This initial period of high loss rate is predicted from the MHD flow theories when the measured, time dependent plasma parameters are substituted into the analytical models. The loss rate determined from the end-on interferograms does not respond to the detailed structure of the plasma loss process.

Analysis of beam loss induced abort kicker instability  

SciTech Connect

Through more than a decade of operation, we have noticed the phenomena of beam loss induced kicker instability in the RHIC beam abort systems. In this study, we analyze the short term beam loss before abort kicker pre-fire events and operation conditions before capacitor failures. Beam loss has caused capacitor failures and elevated radiation level concentrated at failed end of capacitor has been observed. We are interested in beam loss induced radiation and heat dissipation in large oil filled capacitors and beam triggered thyratron conduction. We hope the analysis result would lead to better protection of the abort systems and improved stability of the RHIC operation.

Computing criticality of lines in power systems

Abstract — We propose a computationally efficient method based on nonlinear optimization to identify critical lines, failure of which can cause severe blackouts. Our method computes criticality measure for all lines at a time, as opposed to detecting a single vulnerability, providing a global view of the system. This information on criticality of lines can be used to identify multiple contingencies by selectively exploring multiple combinations of broken lines. The effectiveness of our method is demonstrated on the IEEE 30 and 118 bus systems, where we can very quickly detect the most critical lines in the system and identify severe multiple contingencies.

The Price of Synchrony: Resistive Losses due to Phase Synchronization in Power Networks  

E-Print Network (OSTI)

We investigate the total resistive losses incurred in returning a power network of identical generators to a synchronous state following a transient stability event or in maintaining this state in the presence of persistent stochastic disturbances. We formulate this cost as the input-output $H^2$ norm of a linear dynamical system with distributed disturbances. We derive an expression for the total resistive losses that scales with the size of the network as well as properties of the generators and power lines, but is independent of the network topology. This topologically invariant scaling of what we term the price of synchrony is in contrast to typical power system stability notions like rate of convergence or the region of attraction for rotor-angle stability. Our result indicates that highly connected power networks, whilst desirable for higher phase synchrony, do not offer an advantage in terms of the total resistive power losses needed to achieve this synchrony. Furthermore, if power flow is the mechanism used to achieve synchrony in highly-distributed-generation networks, the cost increases unboundedly with the number of generators.

Digital multimode buck converter control with loss-minimizing synchronous rectifier adaptation  

E-Print Network (OSTI)

Abstract—This paper develops a multimode control strategy which allows for efficient operation of the buck converter over a wide load range. A method for control of synchronous rectifiers as a direct function of the load current is introduced [1]. The function relating the synchronous-rectifier timing to the load current is optimized on-line with a gradient power-loss-minimizing algorithm. Only low-bandwidth measurements of the load current and a power-loss-related quantity are required, making the technique suitable for digital controller implementations. Compared to alternative loss-minimizing approaches, this method has superior adjustment speed and robustness to disturbances, and can simultaneously optimize multiple parameters. The proposed synchronous-rectifier control also accomplishes an automatic, optimal transition to discontinuous-conduction mode at light load. Further, by imposing a minimum duty-ratio, the converter automatically enters pulse-skipping mode at very light load. Thus, the same controller structure can be used in both fixed-frequency pulsewidth modulation and variable-frequency pulse-skipping modes. These techniques are demonstrated on a digitally-controlled 100-W buck converter. Index Terms—Adaptive control, dead-time, digital control, gradient methods, multimode control, optimization methods, pulse skipping, pulsewidth modulated (PWM) power converters, pulsewidth modulation (PWM), synchronous rectifier (SR), variable frequency control.

Development and application of a conceptual approach for defining high-level waste  

SciTech Connect

This paper presents a conceptual approach to defining high-level radioactive waste (HLW) and a preliminary quantitative definition obtained from an example implementation of the conceptual approach. On the basis of the description of HLW in the Nuclear Waste Policy Act of 1982, we have developed a conceptual model in which HLW has two attributes: HLW is (1) highly radioactive and (2) requires permanent isolation via deep geologic disposal. This conceptual model results in a two-dimensional waste categorization system in which one axis, related to ''requires permanent isolation,'' is associated with long-term risks from waste disposal and the other axis, related to ''highly radioactive,'' is associated with short-term risks from waste management and operations; this system also leads to the specification of categories of wastes that are not HLW. Implementation of the conceptual model for defining HLW was based primarily on health and safety considerations. Wastes requiring permanent isolation via deep geologic disposal were defined by estimating the maximum concentrations of radionuclides that would be acceptable for disposal using the next-best technology, i.e., greater confinement disposal (GCD) via intermediate-depth burial or engineered surface structures. Wastes that are highly radioactive were defined by adopting heat generation rate as the appropriate measure and examining levels of decay heat that necessitate special methods to control risks from operations in a variety of nuclear fuel-cycle situations. We determined that wastes having a power density >200 W/m/sup 3/ should be considered highly radioactive. Thus, in the example implementation, the combination of maximum concentrations of long-lived radionuclides that are acceptable for GCD and a power density of 200 W/m/sup 3/ provides boundaries for defining wastes that are HLW.

High channel density wavelength division multiplexer with defined diffracting means positioning  

DOE Patents (OSTI)

A wavelength division multiplexer/demultiplexer is disclosed having optical path lengths between a fiber array and a Fourier transform lens, and between a dispersion grating and the lens equal to the focal length of the lens. The optical path lengths reduce losses due to angular acceptance mismatch in the multiplexer. Close orientation of the fiber array about the optical axis and the use of a holographic dispersion grating reduces other losses in the system. Multi-exposure holographic dispersion gratings enable the multiplexer/demultiplexer for extremely broad-band simultaneous transmission and reflection operation. Individual Bragg plane sets recorded in the grating are dedicated to and operate efficiently on discrete wavelength ranges. 11 figs.

Global yields of the world-s six most widely grown crops--wheat, rice, maize, soybeans, barley, sorghum--have increased since 1961. Year-to-year variations in growing season minimum temperature, maximum temperature, and precipitation explain 30% or more of the variations in yield. Since 1991, climate trends have significantly decreased yield trends in all crops but rice, leading to foregone production since 1981 of about 12 million tons per year of wheat or maize, representing an annual economic loss of $1.2 to $1.7 billion. At the global scale, negative impacts of climate trends on crop yields are already apparent. Annual global temperatures have increased by {approx}0.4 C since 1980, with even larger changes observed in several regions (1). While many studies have considered the impacts of future climate changes on food production (2-5), the effects of these past changes on agriculture remain unclear. It is likely that warming has improved yields in some areas, reduced them in others, and had negligible impacts in still others; the relative balance of these effects at the global scale is unknown. An understanding of this balance would help to anticipate impacts of future climate changes, as well as to more accurately assess recent (and thereby project future) technologically driven yield progress. Separating the contribution of climate from concurrent changes in other factors--such as crop cultivars, management practices, soil quality, and atmospheric carbon dioxide (CO{sub 2}) levels--requires models that describe the response of yields to climate. Studies of future global impacts of climate change have typically relied on a bottom-up approach, whereby field scale, process-based models are applied to hundreds of representative sites and then averaged (e.g., ref 2). Such approaches require input data on soil and management conditions, which are often difficult to obtain. Limitations on data quality or quantity can thus limit the utility of this approach, especially at the local scale (6-8). At the global scale, however, many of the processes and impacts captured by field scale models will tend to cancel out, and therefore simpler empirical/statistical models with fewer input requirements may be as accurate (8, 9). Empirical/statistical models also allow the effects of poorly modeled processes (e.g., pest dynamics) to be captured and uncertainties to be readily quantified (10). Here we develop new, empirical/statistical models of global yield responses to climate using datasets on broad-scale yields, crop locations, and climate variability. We focus on global average yields for the six most widely grown crops in the world: wheat, rice, maize, soybeans, barley, and sorghum. Production of these crops accounts for over 40% of global cropland area (11). 55% of non-meat calories, and over 70% of animal feed (12).

In this paper we show the capabilities of the Large Volume Detector (INFN Gran Sasso National Laboratory) to identify a neutrino burst associated to a supernova explosion, in the absence of an "external trigger", e.g., an optical observation. We describe how the detector trigger and event selection have been optimized for this purpose, and we detail the algorithm used for the on-line burst recognition. The on-line sensitivity of the detector is defined and discussed in terms of supernova distance and electron anti-neutrino intensity at the source.

Elegiac Rhetorics: From Loss to Dialogue in Lyric Poetry  

E-Print Network (OSTI)

By reading mournful poems rhetorically, I expand the concept of the elegy in order to reveal continuities between private and communal modes of mourning. My emphasis on readers of elegies challenges writer-centered definitions of the elegy, like that given by Peter Sacks, who describes how the elegy's formal conventions express the elegist's own motives for writing. Although Sacks's Freudian approach helpfully delineates some of the consoling effects that writing poetry has on the elegist herself, this dissertation revises such writer-centered concepts of the elegy by asking how elegies rhetorically invoke ethical relationships between writers and readers. By reading elegiac poems through Kenneth Burke's rhetorical theories and Emmanuel Levinas's ethics, I argue that these poems characterize, as Levinas suggests, subjectivity as fundamentally structured by ethical relationships with others. In keeping with this ethical focus, I analyze anthology poems, meaning short lyric poems written by acclaimed authors, easily accessible, and easily remembered - including several well-known poems by such authors as Emily Dickinson, Gerard Manley Hopkins, and Robert Frost. Anthology pieces invite ethical evaluation in part because they represent what counts as valuable poetry - and also, by implication, what does not. Because anthology poems are read by broad, diverse audiences, I suggest that a rhetorical methodology focusing on writer-reader relationships is essential to evaluating these poems' ethical implications. This rhetorical approach to poetry, however, questions rhetoricians and aesthetic theorists from Aristotle and Longinus to Lloyd F. Bitzer and Derek Attridge who emphasize distinctions between rhetoric and poetics. I address the ongoing debate about the relationship between rhetoric and poetics by arguing, along the lines of Wayne C. Booth's affirmation that fiction and rhetoric are interconnected, that poetry and rhetoric are likewise integrally tied. To this debate, I add an emphasis on philosophy - from which Plato, Ramus, and others exclude rhetoric and poetry - as likewise essential to understanding both poetry and rhetoric. By recognizing the interrelatedness of these disciplines, we may better clarify poetry's broad, ethical appeals that seem so valuable to readers in situations of loss.

Defining an end state for CO2 sequestration and EOR in North America  

SciTech Connect

CO{sub 2} capture and storage (CCS) presents a challenge to long-range planners, economic interests, regulators, law-makers, and other stakeholders and decision makers. To improve and optimize the use of limited resources and finances, it is important to define an end state for CCS. This ends state should be defined around desired goals and reasonable timelines for execution. While this definition may have substantial technology, policy or economic implications, it need not be prescriptive in terms of technology pathway, policy mechanism, or economic targets. To illustrate these concerns, this paper will present a credible vision of what an end state for North American might look like. From that, examples of key investment and planning decisions are provided to illustrate the value of end-state characterization.

solar reflectance-Part I: Defining a metric that accurately solar reflectance-Part I: Defining a metric that accurately predicts solar heat gain Title Measuring solar reflectance-Part I: Defining a metric that accurately predicts solar heat gain Publication Type Journal Article Year of Publication 2010 Authors Levinson, Ronnen M., Hashem Akbari, and Paul Berdahl Journal Solar Energy Volume 84 Pagination 1717-1744 Keywords Heat Island, Methods & Protocols Abstract Solar reflectance can vary with the spectral and angular distributions of incident sunlight, which in turn depend on surface orientation, solar position and atmospheric conditions. A widely used solar reflectance metric based on the ASTM Standard E891 beam-normal solar spectral irradiance underestimates the solar heat gain of a spectrally selective "cool colored" surface because this irradiance contains a greater fraction of near-infrared light than typically found in ordinary (unconcentrated) global sunlight. At mainland US latitudes, this metric RE891BN can underestimate the annual peak solar heat gain of a typical roof or pavement (slope 5:12 [23°]) by as much as 89 W m-2, and underestimate its peak surface temperature by up to 5 K. Using RE891BN to characterize roofs in a building energy simulation can exaggerate the economic value N of annual cool roof net energy savings by as much as 23%.

Transmission Line Security Monitor: Final Report  

SciTech Connect

The Electric Power Transmission Line Security Monitor System Operational Test is a project funded by the Technical Support Working Group (TSWG). TSWG operates under the Combating Terrorism Technical Support Office that functions under the Department of Defense. The Transmission Line Security Monitor System is based on technology developed by Idaho National Laboratory. The technology provides a means for real-time monitoring of physical threats and/or damage to electrical transmission line towers and conductors as well as providing operational parameters to transmission line operators to optimize transmission line operation. The end use is for monitoring long stretches of transmission lines that deliver electrical power from remote generating stations to cities and industry. These transmission lines are generally located in remote transmission line corridors where security infrastructure may not exist. Security and operational sensors in the sensor platform on the conductors take power from the transmission line and relay security and operational information to operations personnel hundreds of miles away without relying on existing infrastructure. Initiated on May 25, 2007, this project resulted in pre-production units tested in realistic operational environments during 2010. A technology licensee, Lindsey Manufacturing of Azusa California, is assisting in design, testing, and ultimately production. The platform was originally designed for a security monitoring mission, but it has been enhanced to include important operational features desired by electrical utilities.

Experimentally determined level populations of hydrogen excited states from a low-density Z pinch are used as initial conditions in a simulation to derive electron-velocity distributions. These velocity distributions show excess electrons in the high velocity end of the distribution when compared to a Maxwellian velocity distribution. The non-Maxwellian velocity distributions are used to find the nonequilibrium structure factors which are a main component in the plasma line broadening of hydrogen lines. The line profiles generated using the structure factors show plasmon satellites on the wings of the Balmer-..cap alpha..- and -..beta..-line profiles.

Effects of line shifts and the ion quadrupole contribution of spectral line asymmetries.  

SciTech Connect

Line asymmetries and the corresponding shift of spectral lines due to the electron penetration of the radiator orbitals and the ion quadrupole contribution become more significant with increasing principal quantum number and increasing electron density. The mean field static shift due to electron penetration of the orbitals gives rise to an overall shift of the line to lower energy and a significant asymmetry near line center, but does not generate much redhlue far wing asymmetry. The ion quadrupole contribution results in a small blue shift of the spectral line and a small change in asymmetry near line center, but it gives rise to a significant redhlue wing asymmetry in the far wings of the line. Experimental data fiom recent spherical implosion experiments on OMEGA shows evidence of the mean field static shift and may also show the effects of level interactions between the Ar Lyman -{gamma}, -{delta}, -{var_epsilon} lines and also the Ar He -{gamma}, -{delta} lines.

Beam Loss Monitors for NSLS-II Storage Ring  

SciTech Connect

The shielding for the NSLS-II storage ring will provide adequate protection for the full injected beam losses in two cells of the ring around the injection point, but the remainder of the ring is shielded for lower losses of <10% top-off injection beam current. This will require a system to insure that beam losses do not exceed levels for a period of time that could cause excessive radiation exposure outside the shield walls. This beam Loss Control and Monitoring system will have beam loss monitors that will measure where the beam charge is lost around the ring, to warn operators if losses approach the design limits. To measure the charge loss quantitatively, we propose measuring the electron component of the shower as beam electrons hit the vacuum chamber (VC) wall. This will be done using the Cerenkov light as electrons transit ultra-pure fused silica rods placed close to the inner edge of the VC. The entire length of the rod will collect light from the electrons of the spread out shower resulting from the small glancing angle of the lost beam particles to the VC wall. The design and measurements results of the prototype Cerenkov BLM will be presented.

Boiler Tube Corrosion Characterization With a Scanning Thermal Line  

E-Print Network (OSTI)

Wall thinning due to corrosion in utility boiler waterwall tubing is a significant operational concern for boiler operators. Historically, conventional ultrasonics has been used for inspection of these tubes. Unfortunately, ultrasonic inspection is very manpower intense and slow. Therefore, thickness measurements are typically taken over a relatively small percentage of the total boiler wall and statistical analysis is used to determine the overall condition of the boiler tubing. Other inspection techniques, such as electromagnetic acoustic transducer (EMAT), have recently been evaluated, however they provide only a qualitative evaluation - identifying areas or spots where corrosion has significantly reduced the wall thickness. NASA Langley Research Center, in cooperation with ThermTech Services, has developed a thermal NDE technique designed to quantitatively measure the wall thickness and thus determine the amount of material thinning present in steel boiler tubing. The technique involves the movement of a thermal line source across the outer surface of the tubing followed by an infrared imager at a fixed distance behind the line source. Quantitative images of the material loss due to corrosion are reconstructed from measurements of the induced surface temperature variations. This paper will present a discussion of the development of the thermal imaging system as well as the techniques used to reconstruct images of flaws. The application of the thermal line source coupled with the analysis technique represents a significant improvement in the inspection speed and accuracy for large structures such as boiler waterwalls. A theoretical basis for the technique will be presented to establish the quantitative nature of the technique. Further, a dynamic calibration system ...

Forecasting photovoltaic array power production subject to mismatch losses  

Science Conference Proceedings (OSTI)

The development of photovoltaic (PV) energy throughout the world this last decade has brought to light the presence of module mismatch losses in most PV applications. Such power losses, mainly occasioned by partial shading of arrays and differences in PV modules, can be reduced by changing module interconnections of a solar array. This paper presents a novel method to forecast existing PV array production in diverse environmental conditions. In this approach, field measurement data is used to identify module parameters once and for all. The proposed method simulates PV arrays with adaptable module interconnection schemes in order to reduce mismatch losses. The model has been validated by experimental results taken on a 2.2 kW{sub p} plant, with three different interconnection schemes, which show reliable power production forecast precision in both partially shaded and normal operating conditions. Field measurements show interest in using alternative plant configurations in PV systems for decreasing module mismatch losses. (author)

Beam Loss Control for the Fermilab Main Injector  

E-Print Network (OSTI)

From 2005 through 2012, the Fermilab Main Injector provided intense beams of 120 GeV protons to produce neutrino beams and antiprotons. Hardware improvements in conjunction with improved diagnostics allowed the system to reach sustained operation at 400 kW beam power. Losses were at or near the 8 GeV injection energy where 95% beam transmission results in about 1.5 kW of beam loss. By minimizing and localizing loss, residual radiation levels fell while beam power was doubled. Lost beam was directed to either the collimation system or to the beam abort. Critical apertures were increased while improved instrumentation allowed optimal use of available apertures. We will summarize the impact of various loss control tools and the status and trends in residual radiation in the Main Injector.

Initial measurements of fast ion loss in KSTAR  

Science Conference Proceedings (OSTI)

A fast ion loss detector (FILD) has been installed and tested in Korea Superconducting Tokamak Advanced Research (KSTAR). KSTAR FILD measures the energy and the pitch-angle of the escaping ions with the striking positions on the scintillator plane. Measurements of the fast ion loss have been performed for the neutral beam heated plasmas. Initial experimental results indicate the prompt losses from neutral beam are dominant and the effects of the resonant magnetic perturbation on the fast ion loss are investigated. In addition, further design change of the detector-head in order to avoid excessive heat load and to detect the fusion products or the fast ions having order of MeV of energy is also discussed.

Further Results on Forecasting and Model Selection Under Asymmetric Loss  

E-Print Network (OSTI)

: We make three related contributions. First, we propose a new technique for solving prediction problems under asymmetric loss using piecewise-linear approximations to the loss function, and we establish existence and uniqueness of the optimal predictor. Second, we provide a detailed application to optimal prediction of a conditionally heteroskedastic process under asymmetric loss, the insights gained from which are broadly applicable. Finally, we incorporate our results into a general framework for recursive prediction-based model selection under the relevant loss function.

Development of a current collection loss management system for SDI homopolar power supplies  

Science Conference Proceedings (OSTI)

High speed, high power density current collection systems have been identified as an enabling technology required to construct homopolar power supplies to meet SDI missions. This work is part of a three-year effort directed towards the analysis, experimental verification, and prototype construction of a current collection system designed to operate continuously at 2 kA/cm{sup 2}, at a rubbing speed of 200 m/s, and with acceptable losses in a space environment. To data, no system has achieved these conditions simultaneously. This is the annual report covering the second year period of performance on DOE contract DE-AC03-86SF16518. Major areas covered include design, construction and operation of a cryogenically cooled brush test rig, design and construction of a high speed brush test rig, optimization study for homopolar machines, loss analysis of the current collection system, and an application study which defines the air-core homopolar construction necessary to achieve the goal of 80--90 kW/kg generator power density. 17 figs., 2 tabs.

Methodology for Defining Gap Areas between Course-over-ground Locations  

Science Conference Proceedings (OSTI)

Finding all areas that lie outside some distance d from a polyline is a problem with many potential applications. This application of the Visual Sample Plan (VSP) software required finding all areas that were more than distance d from a set of existing paths (roads and trails) represented by polylines. An outer container polygon (known in VSP as a “sample area”) defines the extents of the area of interest. The term “gap area” was adopted for this project, but another useful term might be “negative coverage area.” The project required a polygon solution rather than a raster solution. The search for a general solution provided no results, so this methodology was developed

Based on 143 deg. electrostatic deflectors we have realized a new spectrometer for electron energy loss spectroscopy which is particularly suitable for studies on surface spin waves and other low energy electronic energy losses. Contrary to previous designs high resolution is maintained even for diffuse inelastic scattering due to a specific management of the angular aberrations in combination with an angle aperture. The performance of the instrument is demonstrated with high resolution energy loss spectra of surface spin waves on a cobalt film deposited on the Cu(100) surface.

AC Loss Measurements on a 2G YBCO Coil  

SciTech Connect

The Oak Ridge National Laboratory (ORNL) is collaborating with Waukesha Electric Systems (WES) to continue development of HTS power transformers. For compatibility with the existing power grid, a commercially viable HTS transformer will have to operate at high voltages in the range of 138 kV and above, and will have to withstand 550-kV impulse voltages as well. Second-generation (2G) YBCO coated conductors will be required for an economically-competitive design. In order to adequately size the refrigeration system for these transformers, the ac loss of these HTS coils must be characterized. Electrical AC loss measurements were conducted on a prototype high voltage (HV) coil with co-wound stainless steel at 60 Hz in a liquid nitrogen bath using a lock-in amplifier technique. The prototype HV coil consisted of 26 continuous (without splice) single pancake coils concentrically centered on a stainless steel former. For ac loss measurement purposes, voltage tap pairs were soldered across each set of two single pancake coils so that a total of 13 separate voltage measurements could be made across the entire length of the coil. AC loss measurements were taken as a function of ac excitation current. Results show that the loss is primarily concentrated at the ends of the coil where the operating fraction of critical current is the highest and show a distinct difference in current scaling of the losses between low current and high current regimes.

Electric Power Lines : Questions and Answers on Research into Health Effects.  

Science Conference Proceedings (OSTI)

Most people know that electric power lines, like the wiring in our homes, can cause serious electric shocks if we`re not careful. Many people also want to know whether the electric and magnetic fields (EMF) produced by power lines and other electrical devices cause health effects. The purpose of this pamphlet is to answer some common questions that the Bonneville Power Administration (BPA) receives about the possible effects of power lines on health. (BPA is the Pacific Northwest`s Federal electric power marketing agency.) First, some basic electrical terms are defined, and electric and magnetic fields are described. Next, answers are given to several questions about recent scientific studies. We then describe how BPA is addressing public concerns raised by these studies. Some important information about electrical safety follows. The last section tells you how to obtain more detailed information about the health and safety issues summarized in this pamphlet.

Software-Defined Ultra-wideband Radio Communications: A New RF Technology for Emergency Response Applications  

SciTech Connect

Reliable wireless communication links for local-area (short-range) and regional (long-range) reach capabilities are crucial for emergency response to disasters. Lack of a dependable communication system can result in disruptions in the situational awareness between the local responders in the field and the emergency command and control centers. To date, all wireless communications systems such as cell phones and walkie-talkies use narrowband radio frequency (RF) signaling for data communication. However, the hostile radio propagation environment caused by collapsed structures and rubble in various disaster sites results in significant degradation and attenuation of narrowband RF signals, which ends up in frequent communication breakdowns. To address the challenges of reliable radio communication in disaster fields, we propose an approach to use ultra-wideband (UWB) or wideband RF waveforms for implementation on Software Defined Radio (SDR) platforms. Ultra-wideband communications has been proven by many research groups to be effective in addressing many of the limitations faced by conventional narrowband radio technologies. In addition, LLNL's radio and wireless team have shown significant success in field deployment of various UWB communications system for harsh environments based on LLNL's patented UWB modulation and equalization techniques. Furthermore, using software defined radio platform for UWB communications offers a great deal of flexibility in operational parameters and helps the radio system to dynamically adapt itself to its environment for optimal performance.

Essential elements of modeling gas generation from well defined plutonium materials  

DOE Green Energy (OSTI)

Processing of excess plutonium oxide (and related) materials intended for long-term storage is addressed in DOE standard 3013-2000. The essential elements addressed by this standard are eliminating or reducing to an acceptable level the entities that lead to gas evolution and consequent pressurization of the intended storage container system. Based upon the need to adequately understand and quantify these relevant parameters we briefly describe the current scientific knowledge of gas evolution from such systems. These associated research efforts have included fundamental kinetic and thermodynamic studies of water interactions at actinide oxide surfaces, radiolytic reactions of adsorbed water, interfacial reactions of hydrogen and oxygen, and radiolytic helium production. Utilizing, where possible, experimental parameters for many of the aforementioned processes we have developed a mathematical model with a minimum number of essential components that successfully models gas generation from well-defined PuO{sub 2} materials with known amounts of deliberately added water. In this work we verify this model against real pressure versus time data (described at greater length in another manuscript in these conference proceedings) and subsequently assure the safety envelope of design criteria for both short- and long-term storage and transportation of these material classes. These modeling results predict pressures and gas phase mole fractions over well-defined DOE 3013 container test cases well in advance of actual long-term surveillance information and provide confidence in safe storage of plutonium oxide material classes.

Semantic-driven Parallelization of Loops Operating on User-defined Containers  

SciTech Connect

The authors describe ROSE, a C++ infrastructure for source-to-source translation, that provides an interface for programmers to easily write their own translators for optimizing user-defined high-level abstractions. Utilizing the semantics of these high-level abstractions, they demonstrate the automatic parallelization of loops that iterate over user-defined containers that have interfaces similar to the lists, vectors and sets in the Standard Template Library (STL). The parallelization is realized in two phases. First, they insert OpenMP directives into a serial program, driven by the recognition of the high-level abstractions, containers, that are thread-safe. Then, they translate the OpenMP directives into library routines that explicitly create and manage parallelism. By providing an interface for the programmer to classify the semantics of their abstractions, they are able to automatically parallelize operations on containers, such as linked-lists, without resorting to complex loop dependence analysis techniques. The approach is consistent with general goals within telescoping languages.

Cascaded'' pilot regulators help reduce LPG loss in hot weather  

SciTech Connect

Fina Oil and Chemical Co. and Fisher Controls International used engineering resourcefulness to overcome heat-induced product loss from LPG storage bullets at Fina's Port Arthur, Tex., refinery. Fina had installed Fisher's Easy Joe 399A-6365, a pilot-operated, back-pressure-type regulator, on its LPG storage facility in 1991 as part of a fuel products modernization project. The regulators helped control the accumulation of noncondensible vapors, which collect in the storage bullets above the LPG. But summer heat extremes and surges in the tanks and lines made it possible for the operating pressure to increase so that the safety relief valve was activated before the pilot regulator was able to stabilize the pressure. The installation of pilot-type regulators, in cascaded, or series, formation, reduced product venting through relief valves.

Productivity Improvement of a Manual Assembly Line  

E-Print Network (OSTI)

The current project addresses the productivity improvement of a manual assembly line by making use of operations analysis in the framework of Lean production. A methodology is proposed that helps to improve the productivity of any production process. The methodology consists of selecting a product or product family to be studied followed by current process study. Once the existing process is documented, all the assembly tasks involved must be timed using time study techniques. Operations analysis enables the reduction of non-productive tasks and results in a set of standardized work elements along with the set of standard procedures for performing the operations. Assembly line balancing along with the associated operations analysis assists in constructing or re-configuring an assembly system, which is the key step in improving the overall performance of an assembly line. Following this approach, two manual assembly line configurations (single stage parallel line and five-stage serial line) are constructed for a case study. The results show that by changing over to the single stage assembly line configuration the operator productivity is doubled when compared to the existing assembly method.

Applications of Solar Technology for Catastrophe Response, Claims Management, and Loss Prevention  

DOE Green Energy (OSTI)

Today's insurance industry strongly emphasizes developing cost-effective hazard mitigation programs, increasing and retaining commercial and residential customers through better service, educating customers on their exposure and vulnerabilities to natural disasters, collaborating with government agencies and emergency management organizations, and exploring the use of new technologies to reduce the financial impact of disasters. In June of 1998, the National Renewable Energy Laboratory (NREL) and the National Association of Independent Insurers (NAII) sponsored a seminar titled, ''Solar Technology and the Insurance Industry.'' Presentations were made by insurance company representatives, insurance trade groups, government and state emergency management organizations, and technology specialists. The meeting was attended by insurers, brokers, emergency managers, and consultants from more than 25 US companies. Leading insurers from the personal line and commercial carriers were shown how solar technology can be used in underwriting, claims, catastrophe response, loss control, and risk management. Attendees requested a follow-up report on solar technology, cost, and applications in disasters, including suggestions on how to collaborate with the utility industry and how to develop educational programs for business and consumers. This report will address these issues, with an emphasis on pre-disaster planning and mitigation alternatives. It will also discuss how energy efficiency and renewable technologies can contribute to reducing insurance losses.

Caught in the act: the stage as a backdrop for defining crime in early modern England  

E-Print Network (OSTI)

This study seeks to explicate the complex relationship between crime and drama in early modern England. In a historical context of social, political, and religious upheaval, defining criminality becomes an essential component of maintaining social control when class conflicts often color the administration of justice. Several social stages, including the ceremony of the church, the pomp of the royal court, and the spectacle of criminal punishment, provide a setting in which criminals can be compared to actors. With old power structures reluctantly crumbling in response to economic change, the theater itself emerges as a forum for discussion where themes of corruption in the church and government are introduced. Shakespeare's Measure for Measure, John Webster's The Duchess of Malfi, and Ben Jonson's Bartholomew Fair offer examples of the relative nature of criminality and the unique role of the stage in conglomerating all of the societal stages to comment on their transgressions and shortcomings before an audience comprised of varying social classes.

Methods of defining ontologies, word disambiguation methods, computer systems, and articles of manufacture  

Science Conference Proceedings (OSTI)

Methods of defining ontologies, word disambiguation methods, computer systems, and articles of manufacture are described according to some aspects. In one aspect, a word disambiguation method includes accessing textual content to be disambiguated, wherein the textual content comprises a plurality of words individually comprising a plurality of word senses, for an individual word of the textual content, identifying one of the word senses of the word as indicative of the meaning of the word in the textual content, for the individual word, selecting one of a plurality of event classes of a lexical database ontology using the identified word sense of the individual word, and for the individual word, associating the selected one of the event classes with the textual content to provide disambiguation of a meaning of the individual word in the textual content.

System Losses Study - FIT (Fuel-cycle Integration and Tradeoffs)  

SciTech Connect

This team aimed to understand the broad implications of changes of operating performance and parameters of a fuel cycle component on the entire system. In particular, this report documents the study of the impact of changing the loss of fission products into recycled fuel and the loss of actinides into waste. When the effort started in spring 2009, an over-simplified statement of the objective was “the number of nines” – how would the cost of separation, fuel fabrication, and waste management change as the number of nines of separation efficiency changed. The intent was to determine the optimum “losses” of TRU into waste for the single system that had been the focus of the Global Nuclear Energy Program (GNEP), namely sustained recycle in burner fast reactors, fed by transuranic (TRU) material recovered from used LWR UOX-51 fuel. That objective proved to be neither possible (insufficient details or attention to the former GNEP options, change in national waste management strategy from a Yucca Mountain focus) nor appropriate given the 2009-2010 change to a science-based program considering a wider range of options. Indeed, the definition of “losses” itself changed from the loss of TRU into waste to a generic definition that a “loss” is any material that ends up where it is undesired. All streams from either separation or fuel fabrication are products; fuel feed streams must lead to fuels with tolerable impurities and waste streams must meet waste acceptance criteria (WAC) for one or more disposal sites. And, these losses are linked in the sense that as the loss of TRU into waste is reduced, often the loss or carryover of waste into TRU or uranium is increased. The effort has provided a mechanism for connecting these three Campaigns at a technical level that had not previously occurred – asking smarter and smarter questions, sometimes answering them, discussing assumptions, identifying R&D needs, and gaining new insights. The FIT model has been a forcing function, helping the team in this endeavor. Models don’t like “TBD” as an input, forcing us to make assumptions and see if they matter. A major addition in FY 2010 was exploratory analysis of “modified open fuel” cycles, employing “minimum fuel treatment” as opposed to full aqueous or electrochemical separation treatment. This increased complexity in our analysis and analytical tool development because equilibrium conditions do not appear sustainable in minimum fuel treatment cases, as was assumed in FY 2009 work with conventional aqueous and electrochemical separation. It is no longer reasonable to assume an equilibrium situation exists in all cases.

Results of stereotactic radiosurgery for patients with imaging defined cavernous sinus meningiomas  

Science Conference Proceedings (OSTI)

Introduction: The purpose of this study was to evaluate the efficacy and safety of stereotactic radiosurgery as primary management for patients with imaging defined cavernous sinus meningiomas. Methods: Between 1992 and 2001, 49 patients had radiosurgery for dural-based masses of the cavernous sinus presumed to be meningiomas. The mean patient age was 55.5 years. The mean tumor volume was 10.2 mL; the mean tumor margin dose was 15.9 Gy. The mean follow-up was 58 months (range, 16-144 months). Results: No tumor enlarged after radiosurgery. Twelve of 38 patients (26%) with preexisting diplopia or facial numbness/pain had improvement in cranial nerve function. Five patients (10%) had new (n = 3) or worsened (n = 2) trigeminal dysfunction; 2 of these patients (4%) underwent surgery at 20 and 25 months after radiosurgery despite no evidence of tumor progression. Neither patient improved after partial tumor resection. One patient (2%) developed an oculomotor nerve injury. One patient (2%) had an ischemic stroke related to occlusion of the cavernous segment of the internal carotid artery. Event-free survival was 98%, 85%, and 80% at 1, 3, and 7 years after radiosurgery, respectively. Univariate analysis of patient and dosimetric factors found no analyzed factor correlated with postradiosurgical morbidity. Conclusions: Radiosurgery was an effective primary management strategy for patients with an imaging defined cavernous sinus meningioma. Except in situations of symptomatic mass effect, unusual clinical presentation, or atypical imaging features, surgery to confirm the histologic diagnosis is unlikely to provide clinical benefit.

Design of the ILC RTML Extraction Lines  

SciTech Connect

The ILC [1] Damping Ring to the Main Linac beamline (RTML) contains three extraction lines (EL). Each EL can be used both for an emergency abort dumping of the beam and tune-up continual train-by-train extraction. Two of the extraction lines are located downstream of the first and second stages of the RTML bunch compressor, and must accept both compressed and uncompressed beam with energy spreads of 2.5% and 0.15%, respectively. In this paper we report on an optics design that allowed minimizing the length of the extraction lines while offsetting the beam dumps from the main line by the distance required for acceptable radiation levels in the service tunnel. The proposed extraction lines can accommodate beams with different energy spreads while at the same time providing the beam size acceptable for the aluminum dump window. The RTML incorporates three extraction lines, which can be used for either an emergency beam abort or for a train-by-train extraction. The first EL is located downstream of the Damping Ring extraction arc. The other two extraction lines are located downstream of each stage of the two-stage bunch compressor. The first extraction line (EL1) receives 5GeV beam with an 0.15% energy spread. The extraction line located downstream of the first stage of bunch compressor (ELBC1) receives both compressed and uncompressed beam, and therefore must accept beam with both 5 and 4.88GeV energy, and 0.15% and 2.5% energy spread, respectively. The extraction line located after the second stage of the bunch compressor (ELBC2) receives 15GeV beam with either 0.15 or 1.8% energy spread. Each of the three extraction lines is equipped with the 220kW aluminum ball dump, which corresponds to the power of the continuously dumped beam with 5GeV energy, i.e., the beam trains must be delivered to the ELBC2 dump at reduced repetition rate.

Analyzing Losses: Transuranics into Waste and Fission Products into Recycled Fuel  

SciTech Connect

All mass streams from separations and fuel fabrication are products that must meet criteria. Those headed for disposal must meet waste acceptance criteria (WAC) for the eventual disposal sites corresponding to their waste classification. Those headed for reuse must meet fuel or target impurity limits. A “loss” is any material that ends up where it is undesired. The various types of losses are linked in the sense that as the loss of transuranic (TRU) material into waste is reduced, often the loss or carryover of waste into TRU or uranium is increased. We have analyzed four separation options and two fuel fabrication options in a generic fuel cycle. The separation options are aqueous uranium extraction plus (UREX+1), electrochemical, Atomics International reduction oxidation separation (AIROX), and melt refining. UREX+1 and electrochemical are traditional, full separation techniques. AIROX and melt refining are taken as examples of limited separations, also known as minimum fuel treatment. The fuels are oxide and metal. To define a generic fuel cycle, a fuel recycling loop is fed from used light water reactor (LWR) uranium oxide fuel (UOX) at 51 MWth-day/kg-iHM burnup. The recycling loop uses a fast reactor with TRU conversion ratio (CR) of 0.50. Excess recovered uranium is put into storage. Only waste, not used fuel, is disposed – unless the impurities accumulate to a level so that it is impossible to make new fuel for the fast reactor. Impurities accumulate as dictated by separation removal and fission product generation. Our model approximates adjustment to fast reactor fuel stream blending of TRU and U products from incoming LWR UOX and recycling FR fuel to compensate for impurity accumulation by adjusting TRU:U ratios. Our mass flow model ignores postulated fuel impurity limits; we compare the calculated impurity values with those limits to identify elements of concern. AIROX and melt refining cannot be used to separate used LWR UOX-51 because they cannot separate U from TRU, it is then impossible to make X% TRU for fast reactors with UOX-51 used fuel with 1.3% TRU. AIROX and melt refining can serve in the recycle loop for about 3 recycles, at which point the accumulated impurities displace fertile uranium and the fuel can no longer be as critical as the original fast reactor fuel recipe. UREX+1 and electrochemical can serve in either capacity; key impurities appear to be lanthanides and several transition metals.

The Heat Loss Analysis and Commissioning of a Commercial Helium Dewar (SULI paper)  

SciTech Connect

A low temperature cryostat suitable for many different experiments will be commissioned at the cryogenic test facility at SLAC. The scope of the project is to make commission a commercial Helium dewar. The building of the top flange will be followed from its design phase through to its finished assembly. In addition, diagnostic tools such as thermometry, level detector, pressure gauge, transfer lines for He and N2, vent lines with relief valves for He and N2 will be incorporated. Instrumentation to read and plot this data will also be included. Once the cryostat is assembled, we will cool down the cryostat to measure its performance. A typical consumption rate of Helium will be measured and from this, the overall heat leak to the dewar will be calculated. A processing instrumentation diagram (PID) of the dewar system was created with SolidEdge and was later approved and published as an official SLAC document. The plots comparing the liquid level changes of the 36 inch probe with the time and the heat loss as a function of time proved to be a valid indication that the data was interpreted and recorded correctly and that the dewar was put together successfully.

Classical strongly coupled quark-gluon plasma. VII. Energy loss  

Science Conference Proceedings (OSTI)

We use linear response analysis and the fluctuation-dissipation theorem to derive the energy loss of a heavy quark in the SU(2) classical Coulomb plasma in terms of the l=1 monopole and nonstatic structure factor. The result is valid for all Coulomb couplings {Gamma}=V/K, the ratio of the mean potential to kinetic energy. We use the Liouville equation in the collisionless limit to assess the SU(2) nonstatic structure factor. We find the energy loss to be strongly dependent on {Gamma}. In the liquid phase with {Gamma}{approx_equal}4, the energy loss is mostly metallic and soundless with neither a Cerenkov nor a Mach cone. Our analytical results compare favorably with the SU(2) molecular dynamics simulations at large momentum and for heavy quark masses.

Gas-rich sediment and coastal wetland loss in Louisiana  

SciTech Connect

High rates of wetland loss in southern Louisiana provide the impetus for examining the role that trapped, biogenic gases play in regulating subsidence of coastal areas. A significant cause for wetland loss in this region is relative sea-level rise produced by sediment-volume reduction. Dewatering, grain reorientation and packing, and oxidation of organic-rich sediments are thought to be the main processes for volume loss. It is argued that natural and anthropogenic causes for sediment degasification play a critical role in sediment-volume reduction. Compressional wave velocities were measured at 34 sites in both the abandoned (Holocene) and modern parts of the Mssissippi Delta. A low-frequency source (<200 Hz) was used to maximize sound-wave dispersion caused by interstitial gas bubbles. Compressional wave velocities measured at low frequencies relative to the gas-bubble resonant-frequency undergo maximum change from the velocity for a gas-free sediment.

H- AND PROTON BEAM LOSS COMPARISON AT SNS SUPERCONDUCTING LINAC  

Science Conference Proceedings (OSTI)

A comparison of beam loss in the superconducting part (SCL) of the Spallation Neutron Source (SNS) linac for H- and protons is presented. During the experiment the nominal beam of negative hydrogen ions in the SCL was replaced by a proton beam created by insertion of a thin stripping carbon foil placed in the low energy section of the linac. The observed significant reduction in the beam loss for protons is explained by a domination of the intra beam stripping mechanism of the beam loss for H-. The details of the experiment are discussed, and a preliminary estimation of the cross section of the reaction H- + H- -> H- + H0 + e is presented. Earlier, a short description of these studies was presented in [1].

Fluid loss to formation stopped prior to gravel packing  

Science Conference Proceedings (OSTI)

Union Texas Petroleum has combined special techniques in offshore Louisiana gravel-packing operations to combat severe fluid loss that had jeopardized previous gravel-packed completions. By using an annulus pressure-controlled circulation valve and a crosslinked polymer gelled block, Union Texas was able to totally halt loss of fluid to a formation that had an 1,835-psi overbalanced (the hydrostatic pressure of well fluid in the treating string-to-casing annulus exceeded formation pressure by 1,835 psi). The pressure-controlled valve permitted process control without pipe movement, and the gelled block prevented fluid loss to the formation while the gravel pack was being installed. The well was perforated underbalanced, using tubing-conveyed guns, for perforation cleanup.

ANALYZING SURFACE ROUGHNESS DEPENDENCE OF LINEAR RF LOSSES  

SciTech Connect

Topographic structure on Superconductivity Radio Frequency (SRF) surfaces can contribute additional cavity RF losses describable in terms of surface RF reflectivity and absorption indices of wave scattering theory. At isotropic homogeneous extent, Power Spectrum Density (PSD) of roughness is introduced and quantifies the random surface topographic structure. PSD obtained from different surface treatments of niobium, such Buffered Chemical Polishing (BCP), Electropolishing (EP), Nano-Mechanical Polishing (NMP) and Barrel Centrifugal Polishing (CBP) are compared. A perturbation model is utilized to calculate the additional rough surface RF losses based on PSD statistical analysis. This model will not consider that superconductor becomes normal conducting at fields higher than transition field. One can calculate the RF power dissipation ratio between rough surface and ideal smooth surface within this field range from linear loss mechanisms.

Loss of benefits resulting from mandated nuclear plant shutdowns  

SciTech Connect

This paper identifies and discusses some of the important consequences of nuclear power plant unavailability, and quantifies a number of technical measures of loss of benefits that result from regulatory actions such as licensing delays and mandated nuclear plant outages. The loss of benefits that accompany such regulatory actions include increased costs of systems generation, increased demand for nonnuclear and often scarce fuels, and reduced system reliability. This paper is based on a series of case studies, supplemented by sensitivity studies, on hypothetical nuclear plant shutdowns. These studies were developed by Argonne in cooperation with four electric utilities.

Distilling single-photon entanglement from photon loss and decoherence  

E-Print Network (OSTI)

Single-photon entanglement may be the simplest type of entanglement but it is of vice importance in quantum communication. Here we present a practical protocol for distilling the single-photon entanglement from both photon loss and decoherence. With the help of some local single photons, the probability of single photon loss can be decreased and the less-entangled state can also be recovered to maximally entangled state simultaneously. It only requires some linear optical elements which makes it feasible in current experiment condition. This protocol might find applications in current quantum communications based on the quantum repeaters.

Passive magnetic bearing element with minimal power losses  

DOE Patents (OSTI)

Systems employing passive magnetic bearing elements having minimal power losses are provided. Improved stabilizing elements are shown, employing periodic magnet arrays and inductively loaded circuits, but with improved characteristics compared to the elements disclosed in U.S. Patent No. 5,495,221 entitled "Dynamically Stable Magnetic Suspension/Bearing System." The improvements relate to increasing the magnitude of the force derivative, while at the same time reducing the power dissipated during the normal operation of the bearing system, to provide a passive bearing system that has virtually no losses under equilibrium conditions, that is, when the supported system is not subject to any accelerations except those of gravity.

Implementation of Beam-Loss Monitor systems for the SSC  

Science Conference Proceedings (OSTI)

Beam-Loss Monitors (BLM) are used with each accelerator in the Superconducting Super Collider complex. The primary purpose of these detectors is to protect the accelerators from damage due to the loss of protons. Although the range of primary beam energies to be covered is very large, 20 MeV to 20 TeV, we plan to maintain commonality of detectors and electronics as much as possible. In this report the plans for developing and implementing BLM systems for each of the accelerators will be discussed. Possible solutions to problems that have been identified are presented.

Beam Loss Monitors for NSLS-II Storage Ring  

Science Conference Proceedings (OSTI)

The shielding for the NSLS-II storage ring will provide adequate protection for the full injected beam losses in two cells of the ring around the injection point, but the remainder of the ring is shielded for lower losses of Cerenkov light as electrons transit ultra-pure fused silica rods placed close to the inner edge of the VC. The entire length of the rod will collect light from the electrons of the spread out shower resulting from the small glancing angle of the lost beam particles to the VC wall. The design and measurements results of the prototype Cerenkov BLM will be presented.

The Los Alamos Neutron Science Center (LANSCE) currently provides 100-MeV H{sup +} and 800-MeV H{sup -} beams to several user facilities that have distinct beam requirements, e.g. intensity, micropulse pattern, duty factor, etc. Minimizing beam loss is critical to achieving good performance and reliable operation, but can be challenging in the context of simultaneous multi-beam delivery. This presentation will discuss various aspects related to the observation, characterization and minimization of beam loss associated with normal production beam operations in the linac.

Predictions of convective losses from a solar cavity receiver  

SciTech Connect

Convective losses arising from buoyancy driven flow were calculated for a two-dimensional model simulating a solar cavity receiver. The TEMPEST code, capable of fully three-dimensional coupled thermal-hydraulic transient calculations, was used for the simulation. Predicted velocity and temperature results for a 2.59 m deep by 2.88 m high rectangular cavity with an aperture opening of 1.72 m were used to determine convective losses for prescribed interior wall temperatures and cavity orientation. Velocity vector and temperature isotherm plots were used to analyze flow characteristics.

Energy Loss in Nuclear Drell-Yan Process  

E-Print Network (OSTI)

By means of the nuclear parton distributions which can be used to provide a good explanation for the EMC effect in the whole x range, we investigate the energy loss effect in nuclear Drell-Yan process. When the cross section of lepton pair production is considered varying with the center-of-mass energy of the nucleon-nucleon collision, we find that the nuclear Drell-Yan(DY) ratio is suppressed due to the energy loss, which balances the overestimate of the DY ratio only in consideration of the effect of nuclear parton distributions.

Energy-loss rate of a fast particle in graphene  

SciTech Connect

The energy-loss rate of a fast particle in graphene is studied. The energy-loss rate always increases with increasing incident particle energy, which is quite unusual when compared to electron gas in normal metal. Graphene exhibits a ''discriminating'' behavior where there exists a low energy cut-off below which the scattering process is strictly forbidden, leading to lossless traverse of an external particle in graphene. This low energy cutoff is of the order of nearest neighbor hopping bandwidth. Our results suggest that backscattering is also absent in the external particle scattering of graphene.

Well-defined ultrathin Pd films on Pt(111): electrochemical preparation and interfacial chemistry  

E-Print Network (OSTI)

Well-defined ultrathin films of palladium, with coverages ranging from submonolayer, ?Pd = 0.5 monolayer (ML), to multilayer, ?P d = 8 ML, were electrochemically deposited on Pt(111) using potentiostatic and potentiodynamic methods. In both methods, between the coverage regimes studied, the growth of the Pd films follows the Stranski-Krastanov mechanism. The interfacial electrochemical properties associated with the film-to-bulk transition were characterized by conventional voltammetric techniques in combination with low-energy electron diffraction (LEED) and Auger electron spectroscopy (AES). The voltammetric peaks associated with H-atom adsorption and desorption on terrace sites indicate that the Pd electrodeposit starts to exhibit bulk-like properties at a coverage of 3 ML. Voltammetric cycling, in sulfuric acid solution, between the hydrogen evolution and the double-layer regions, was found to exert minimal influence on the annealing (smoothening) of the electrodeposited Pd films. However, cycling within the same potential region in the presence of bromide anions (at which Br- adsorption/Br desorption takes place) smoothens the initially rough Pd films essentially as well as high-temperature annealing. The influence of chemisorbed bromine on the anodic dissolution of Pd was also studied; this was for comparison with previous work on the anodic dissolution of Pd, in inert electrolyte, catalyzed by chemisorbed iodine. The present studies indicated that a small but measurable amount of bromine was desorbed along with dissolution of the Pd step atoms; bromine at the Pd terrace behaved identically to iodine in that the coverage of iodine is maintained regardless of the amount or origin of the of anodically stripped Pd. Atomically smooth, well-defined ultrathin Pd films were prepared by a constant potential deposition (CPD) method followed by multiple potential cycles, in dilute Brsolution, within the double-layer region and reductive removal of Brads, by simple emersion at a potential just before the hydrogen evolution reaction potential (EHER). A previously adapted method for the same purpose involved the chemisorption of iodine onto ultrathin PdCPD films, from dilute I- solution, followed by reductive desorption of Iads in iodide-free solution at pH 10 and at a potential just before EHER.

Design and Analyses of Transmission Lines for the 110 GHzECH Upgrade to 6 MW for DIII-D  

SciTech Connect

During the summer of 1999 the installation of three new Electron Cyclotron Heating (ECH) transmission lines began as part of the 110 GHz ECH Upgrade to 6 MW project for DIII-D. An important step in the development of the transmission line design was the selection of the waveguide size. To make this selection, analyses were conducted to characterize the thermal and radio frequency (rf) loss performance of the key corrugated waveguide components under 1 MW, long pulse (10 s, 1% duty cycle) operation. Other factors that were analyzed included vacuum conductance and pumping speed, ease of installation, space considerations, and overall cost. The two candidate transmission line sizes were 2.50 in. and 1.25 in. id. An overview of the design and layout of the proposed transmission lines for the DIII-D ECH upgrade project is presented. Details and results are given for the vacuum conductance analysis of the overall transmission line, the rf loss analyses and tests on corrugated waveguide and miter bends, and the thermal analyses of the mirrors in the corrugated waveguide switch and the power monitor miter bend. Finally, a discussion is presented which weighs the results of these analyses with the experience gained through the installation and operation of the existing three 1 MW ECH systems at DIII-D and concludes with the selection of 1.25 in. i.d. waveguide and components for the upgrade project.

Dissolution of FB-Line Cabinet Sweepings  

DOE Green Energy (OSTI)

Three FB-Line samples were received by the Savannah River National Laboratory (SRNL) for characterization and evaluation for suitability for HB-Line dissolution. These samples are part of a larger sampling/evaluation program in support of FB-Line deinventory efforts. The samples studied were identified as MC04-147- HBL, MC04-148-HBL, and FBL-SWP-04-016-HBL (N). The first sample, MC04-147-HBL, is a portion of FB-Line Packaging and Stabilization (P&S) materials. The second sample, MC04-148-HBL, is a sweeping from Cabinet 6-8, which is not representative of the mechanical line. The third sample, FBL-SWP-04-016-HBL (N), is an FB-Line North cabinet sweeping. The samples were described by FB-Line personnel as containing plutonium oxide (PuO{sub 2}) which had not been high-fired. This description was generally confirmed by solids analysis and off gas measurements. All three samples were dissolved in 8 M HNO{sub 3}/0.1 M KF at 90-100 C leaving minor amounts of solid residue. During dissolution, sample MC04-147 did not generate hydrogen gas. Sample MC04-148 generated modest amounts of gas, which contained 4.0 to 4.7 volume percent (vol %) hydrogen (H{sub 2}) at a ratio of up to 8.4 x 10{sup -5} mol H{sub 2}/g sample. Sample FBL-SWP-04-016-HBL (N) was nearly completely soluble in 8 M HNO{sub 3}and produced a very small amount of gas. Apparently, the CaF{sub 2} in that sample dissolves and provides sufficient fluoride to support the dissolution of other components.

Measuring solar reflectance - Part I: Defining a metric that accurately predicts solar heat gain  

Science Conference Proceedings (OSTI)

Solar reflectance can vary with the spectral and angular distributions of incident sunlight, which in turn depend on surface orientation, solar position and atmospheric conditions. A widely used solar reflectance metric based on the ASTM Standard E891 beam-normal solar spectral irradiance underestimates the solar heat gain of a spectrally selective ''cool colored'' surface because this irradiance contains a greater fraction of near-infrared light than typically found in ordinary (unconcentrated) global sunlight. At mainland US latitudes, this metric R{sub E891BN} can underestimate the annual peak solar heat gain of a typical roof or pavement (slope {roofs in a building energy simulation can exaggerate the economic value N of annual cool roof net energy savings by as much as 23%. We define clear sky air mass one global horizontal (''AM1GH'') solar reflectance R{sub g,0}, a simple and easily measured property that more accurately predicts solar heat gain. R{sub g,0} predicts the annual peak solar heat gain of a roof or pavement to within 2 W m{sup -2}, and overestimates N by no more than 3%. R{sub g,0} is well suited to rating the solar reflectances of roofs, pavements and walls. We show in Part II that R{sub g,0} can be easily and accurately measured with a pyranometer, a solar spectrophotometer or version 6 of the Solar Spectrum Reflectometer. (author)

Defining How a Microbial Cell Senses and Responds to a Redox Active Environment  

Science Conference Proceedings (OSTI)

This grant was for four years, and the work was designed to look at the mechanisms of extracellular electron transfer by the dissimilatory iron reducing bacteria Shewanella oneidensis MR-1, and other closely related Shewanella strains and species. During this work, we defined many of the basic physiological and biochemical properties of the Shewanella group, Much of which was summarized in review articles. We also finished and published the genome sequence of strain MR-1, the first of the shewanellae to have its genome sequenced. Control at the transcriptional and translational level was studied in collaboration with colleagues at PNNL and ANL. We utilized synchrotron X-ray radiation to image both the bacteria and the metal oxide particles via a technique called STXM, synchrotron X-ray absorption (ref. No.9), and X-ray microbeam analysis. We purified several of the cytochromes involved with metal reduction, and improved gene annotation of the MR-1 genome. The conductive appendages (nanowires) of MR-1 were described and characterized. Comparative genomics and biochemistry revealed that the pathway for the utilization of N-acetyl glucosamine in the various strains of Shewanella exhibited great variability, and had a number of previously unknown genes.

System Energy Assessment (SEA), Defining a Standard Measure of EROI for Energy Businesses as Whole Systems  

E-Print Network (OSTI)

A more objective method for measuring the energy needs of businesses, System Energy Assessment (SEA), identifies the natural boundaries of businesses as self-managing net-energy systems, of controlled and self-managing parts. The method is demonstrated using a model Wind Farm case study, and applied to defining a true physical measure of its energy productivity for society (EROI-S), the global ratio of energy produced to energy cost. The traceable needs of business technology are combined with assignable energy needs for all other operating services. That serves to correct a large natural gap in energy use information. Current methods count traceable energy receipts for technology use. Self-managing services employed by businesses outsource their own energy needs to operate, and leave no records to trace. Those uncounted energy demands are often 80% of the total embodied energy of business end products. The scale of this "dark energy" was discovered from differing global accounts, and corrected so the average...

Site-Wide Integrated Water Monitoring -- Defining and Implementing Sampling Objectives to Support Site Closure  

SciTech Connect

The Underground Test Area (UGTA) activity is responsible for assessing and evaluating the effects of the underground nuclear weapons tests on groundwater at the Nevada National Security Site (NNSS), formerly the Nevada Test Site (NTS), and implementing a corrective action closure strategy. The UGTA strategy is based on a combination of characterization, modeling studies, monitoring, and institutional controls (i.e., monitored natural attenuation). The closure strategy verifies through appropriate monitoring activities that contaminants of concern do not exceed the SDWA at the regulatory boundary and that adequate institutional controls are established and administered to ensure protection of the public. Other programs conducted at the NNSS supporting the environmental mission include the Routine Radiological Environmental Monitoring Program (RREMP), Waste Management, and the Infrastructure Program. Given the current programmatic and operational demands for various water-monitoring activities at the same locations, and the ever-increasing resource challenges, cooperative and collaborative approaches to conducting the work are necessary. For this reason, an integrated sampling plan is being developed by the UGTA activity to define sampling and analysis objectives, reduce duplication, eliminate unnecessary activities, and minimize costs. The sampling plan will ensure the right data sets are developed to support closure and efficient transition to long-term monitoring. The plan will include an integrated reporting mechanism for communicating results and integrating process improvements within the UGTA activity as well as between other U.S. Department of Energy (DOE) Programs.

Dispersion measurement as a method of quantifying geologic characterization and defining reservoir heterogeneity. Final report  

Science Conference Proceedings (OSTI)

The main objective of this research project is to investigate dispersion as a method of quantifying geological characterization and defining reservoir heterogeneity in order to enhance crude oil recovery. The dispersion of flow of a reservoir rock (dispersion coefficient and dispersivity) was identified as one of the physical properties of a reservoir rock by measuring the mixing of two miscible fluids, one displacing the other in a porous medium. A rock was 100% saturated with a resident fluid and displaced by a miscible fluid of equal viscosity and equal density. Some specific experiments were performed with unequal densities. Produced fluid was analyzed by refractometer, nuclear reaction, electrical conductivity and X-ray scan. Several physical and flow characteristics were measured on the sand rock sample in order to establish correlations with the measured dispersion property. Absolute permeability, effective porosity, relative permeability, capillary pressure, the heterogeneity factor and electrical conductivity were used to better understand the flow system. Linear, transverse, 2-D and 3-D dispersions were measured and used to characterize the rock heterogeneity of the flow system. A new system of measuring dispersion was developed using a gas displacing gas system in a porous medium. An attempt was also made to determine the dispersion property of an actual reservoir from present day well log data on a producing well. 275 refs., 102 figs., 17 tabs.

USING CFD TO ANALYZE NUCLEAR SYSTEMS BEHAVIOR: DEFINING THE VALIDATION REQUIREMENTS  

SciTech Connect

A recommended protocol to formulate numeric tool specifications and validation needs in concert with practices accepted by regulatory agencies for advanced reactors is described. The protocol is based on the plant type and perceived transient and accident envelopes that translates to boundary conditions for a process that gives the: (a) key phenomena and figures-of-merit which must be analyzed to ensure that the advanced plant can be licensed, (b) specification of the numeric tool capabilities necessary to perform the required analyses—including bounding calculational uncertainties, and (c) specification of the validation matrices and experiments--including the desired validation data. The result of applying the process enables a complete program to be defined, including costs, for creating and benchmarking transient and accident analysis methods for advanced reactors. By following a process that is in concert with regulatory agency licensing requirements from the start to finish, based on historical acceptance of past licensing submittals, the methods derived and validated have a high probability of regulatory agency acceptance.

MCP Upgrade: Transmission Line and Pore Importance  

E-Print Network (OSTI)

In order to take advantage of all of the benefits of Multi-Channel Plate Photo-Multiplier Tubes (MCPs) a fast and efficient readout scheme must be implemented. One scheme that appears very promising is that of a transmission line coupled to a digital sampling readout. Transmission line readout allows for 2D position reconstruction, as well as an extremely fast response time, allowing for an exceptional timing resolution. I will be discussing the development of a method to connect the transmission line readout to the anode of the MCP, as well as testing the resultant MCP-transmission line readout system. This testing occurred at Argonnes laser lab, which featured a tunable fast rise time laser as well as a data acquisition system with a low noise level. A study to determine the importance of the pore size of the MCP was also carried out at Argonnes laser lab. In this study two MCPs which differed only in pore size (25µm and 10µm) were tested and their timing resolutions were compared. The objective of the following discussion is to quantify the effectiveness of the transmission line readout, learn more about the nature of the MCP and its signals, and look for ways in which to improve upon the present readout technique. 2 Tyler Natoli 1

A high accuracy computed water line list  

E-Print Network (OSTI)

A computed list of H$_{2}$$^{16}$O infra-red transition frequencies and intensities is presented. The list, BT2, was produced using a discrete variable representation two-step approach for solving the rotation-vibration nuclear motions. It is the most complete water line list in existence, comprising over 500 million transitions (65% more than any other list) and it is also the most accurate (over 90% of all known experimental energy levels are within 0.3 cm$^{-1}$ of the BT2 values). Its accuracy has been confirmed by extensive testing against astronomical and laboratory data. The line list has been used to identify individual water lines in a variety of objects including: comets, sunspots, a brown dwarf and the nova-like object V838 Mon. Comparison of the observed intensities with those generated by BT2 enables physical values to be derived for these objects. The line list can also be used to provide an opacity for models of the atmospheres of M-dwarf stars and assign previously unknown water lines in laboratory spectra.

Measurements of AC Losses and Current Distribution in Superconducting Cables  

Science Conference Proceedings (OSTI)

This paper presents our new experimental facility and techniques to measure ac loss and current distribution between the layers for High Temperature Superconducting (HTS) cables. The facility is powered with a 45 kVA three-phase power supply which can provide three-phase currents up to 5 kA per phase via high current transformers. The system is suitable for measurements at any frequency between 20 and 500 Hz to better understand the ac loss mechanisms in HTS cables. In this paper, we will report techniques and results for ac loss measurements carried out on several HTS cables with and without an HTS shielding layer. For cables without a shielding layer, care must be taken to control the effect of the magnetic fields from return currents on loss measurements. The waveform of the axial magnetic field was also measured by a small pick-up coil placed inside a two-layer cable. The temporal current distribution between the layers can be calculated from the waveform of the axial field.

A utility framework for bounded-loss market makers  

E-Print Network (OSTI)

We introduce a class of utility-based market makers that always accept orders at their risk-neutral prices. We derive necessary and sufficient conditions for such market makers to have bounded loss. We prove that hyperbolic absolute risk aversion utility market makers are equivalent to weighted pseudospherical scoring rule market makers. In particular, Hanson’s logarithmic scoring rule market maker corresponds to a negative exponential utility market maker in our framework. We describe a third equivalent formulation based on maintaining a cost function that seems most natural for implementation purposes, and we illustrate how to translate among the three equivalent formulations. We examine the tradeoff between the market’s liquidity and the market maker’s worst-case loss. For a fixed bound on worst-case loss, some market makers exhibit greater liquidity near uniform prices and some exhibit greater liquidity near extreme prices, but no market maker can exhibit uniformly greater liquidity in all regimes. For a fixed minimum liquidity level, we give the lower bound of market maker’s worst-case loss under some regularity conditions. 1

Discrete-Time Block Models for Transmission Line Channels: Static and Doubly Selective Cases  

E-Print Network (OSTI)

Most methodologies for modeling Transmission Line (TL) based channels define the input-output relationship in the frequency domain (FD) and handle the TL resorting to a two-port network (2PN) formalism. These techniques have not yet been formally mapped into a discrete-time (DT) block model, which is useful to simulate and estimate the channel response as well as to design optimal precoding strategies. TL methods also fall short when they are applied to Time Varying (TV) systems, such as the power line channel. The objective of this paper is to establish if and how one can introduce a DT block model for the Power Line Channel. We prove that it is possible to use Lifting and Trailing Zeros (L&TZ) techniques to derive a DT block model that maps the TL-based input-output description directly in the time domain (TD) block channel model. More specifically, we find an interesting relationship between the elements of an ABCD matrix, defined in the FD, and filtering kernels that allow an elegant representation of...

Cytogenetic characterization of three cell lines derived from primary cervical tumors of different histologic grade  

SciTech Connect

Braum et al.(1993) established three cell lines from keratinizing and nonkeratinizing cervical carcinomas. These cell lines were subsequently analyzed for growth properties and the physical state of the human papillomavirus type 16 genome. TC140, derived from a keratinizing cervical tumor, contains human papillomavirus type 16 in the episomal state. TC-146A and TC-146B, derived from a nonkeratinizing large-cell cervical carcinoma, contain human papillomavirus type 16 in the integrated state. The goal of the present study was to cytogenetically characterize these cell lines, developed from cervical carcinoma with a defined histopathology, in order to shed additional light on the biological basis of the histological and clinical heterogeneity of cervical cancers. Information on solid tumors has been limited because they are often difficult to culture and the karyotypes on the available metaphases are often complex with unidentifiable markers. The chromosomes of these three cell lines were characterized in the present study using GTG-banding. For cell line 140, the most striking chromosomal abnormalities noted were the presence of an i(5p) or i(12p) marker, an isochromosome 8q marker and multiple copies of chromosome 9. For cell line 146A, the most notable chromosomal abnormalities noted were the presence of a marker chromosome 7 with additional materials present on the long arms, an isochomosome of the long arms of chromosome 8 and a question of chromosome 19 markers. For cell line 146B, the most notable chromosomal abnormalities were found to be a deleted X chromosome, a marker chromosome 7 with additional material on the long arm, an isochromosome 8q marker, and isochromosome 16q marker and one or more copies of an isochromosome 17q marker. Fluorescent in situ hybridization experiments performed using select probes further corroborate the results of the above-mentioned conventional cytogenetic studies.

Theoretical mass loss rates of cool main-sequence stars  

E-Print Network (OSTI)

We develop a model for the wind properties of cool main-sequence stars, which comprises their wind ram pressures, mass fluxes, and terminal wind velocities. The wind properties are determined through a polytropic magnetised wind model, assuming power laws for the dependence of the thermal and magnetic wind parameters on the stellar rotation rate. We use empirical data to constrain theoretical wind scenarios, which are characterised by different rates of increase of the wind temperature, wind density, and magnetic field strength. Scenarios based on moderate rates of increase yield wind ram pressures in agreement with most empirical constraints, but cannot account for some moderately rotating targets, whose high apparent mass loss rates are inconsistent with observed coronal X-ray and magnetic properties. For fast magnetic rotators, the magneto-centrifugal driving of the outflow can produce terminal wind velocities far in excess of the surface escape velocity. Disregarding this aspect in the analyses of wind ram pressures leads to overestimations of stellar mass loss rates. The predicted mass loss rates of cool main-sequence stars do not exceed about ten times the solar value. Our results are in contrast with previous investigations, which found a strong increase of the stellar mass loss rates with the coronal X-ray flux. Owing to the weaker dependence, we expect the impact of stellar winds on planetary atmospheres to be less severe and the detectability of magnetospheric radio emission to be lower then previously suggested. Considering the rotational evolution of a one solar-mass star, the mass loss rates and the wind ram pressures are highest during the pre-main sequence phase.

NNSA's next generation safeguards initiative to define an effective state system of accounting and control  

SciTech Connect

The International Nuclear Safeguards and Engagement Program (INSEP), the international outreach component of the Next Generation Safeguards Initiative (NGSI), is a collaborative program that endeavors to strengthen international safeguards at all stages of nuclear development. One of the critical ways the program achieves this objective is through working with partners to increase the effectiveness of the State System of Accountancy for and Control of Nuclear Materials (SSAC) - the essential elements of national, regulatory and facility safeguards competencies that work as a system to provide the International Atomic Energy Agency (IAEA) and the world the full assurance of the state's adherence to its safeguards agreements. INSEP provides assistance in developing a state's SSAC in a number of areas, from developing national legislation governing the possession and use of nuclear material to working with nuclear facility operators to developing good practices in waste management. INSEP has collaborated with foreign partners in peaceful nuclear applications for over two decades, but recently, it has focused its efforts on strengthening SSACs due to the growth of nuclear power worldwide, particularly in countries with limited nuclear infrastructures. This new area of focus has prompted INSEP to develop a model of SSAC competencies that will serve not only as a structure for its engagement with partner states, but also as a means to facilitate coordination with other states that provide training and assistance, and as a mechanism for evaluating the effectiveness of its work in reaching its intended objectives. While this model uses as its starting point the requirements on a State that are presented in the Comprehensive Safeguards Agreement and the Additional Protocol, it is not, in itself, a requirements document or guidance for implementing requirements. It is rather an analysis of what capabilities will be needed in a State to be able to meet requirements and to build confidence in the State System. Viewed from this perspective, the model can be thought of as a quality assurance tool that assists states in ensuring that the outputs of their State System (the tangible 'goods' that are provided to the International Atomic Energy Agency under the State's agreements) are of high quality. As such, this tool is for the internal use of a State System that wishes to assess and improve its capacity. It is not intended for comparison or outside evaluation. In addition to providing a self-assessment tool, INSEP expects this model to be useful in several other ways: it will inform the approach that INSEP uses in bilateral consultations to identify areas where INSEP outreach and training may be of value, and it will provide a structure for its training curriculum. It will help INSEP to evaluate the effectiveness of its outreach - where there are gaps in the training provided, and whether the training that is provided meets its stated objectives. Finally, it will provide a framework for coordinating with the IAEA and other member states in the 'harmonization' efforts currently underway to align the outreach efforts of states that provide safeguards training. This paper describes the process of evaluation that INSEP is developing. It looks at the expected usefulness of the metrics for conducting self-assessments and joint assessments and enabling partners to identify training needs. The paper begins with a description of various performance requirements that define what must be done at the state and facility level to implement effective and efficient international safeguards. Next, technical performance measures are discussed, that define how well a state and its facilities are fulfilling these requirements. Then a functional analysis is conducted to align the technical requirements with competencies and determine who should carry out the various activities necessary to fulfill the performance requirements.

Inductive gas line for pulsed lasers  

DOE Patents (OSTI)

A gas laser having a metal inlet gas feed line assembly shaped as a coil, to function as an electrical inductance and therefore high impedance to pulses of electric current applied to electrodes at opposite ends of a discharge tube of a laser, for example. This eliminates a discharge path for the laser through the inlet gas feed line. A ferrite core extends through the coil to increase the inductance of the coil and provide better electric isolation. By elimination of any discharge breakdown through the gas supply, efficiency is increased and a significantly longer operating lifetime of the laser is provided.

Science Conference Proceedings (OSTI)

A thermostat that provides reliable, accurate temperature control is the key to a comfortable, efficient space-heating system. The lack of a commercially available line-voltage thermostat that is affordable and performs well has been a significant factor in limiting the comfort and popularity of zoned residential electric heating systems. With EPRI support, two manufacturers have developed innovative, electronics-based line-voltage thermostats that offer a cost-effective control option for creating a comfortable environment with zoned electric heat. These thermostats also may help reduce energy consumption.

Measuring solar reflectance Part I: Defining a metric that accurately predicts solar heat gain  

SciTech Connect

Solar reflectance can vary with the spectral and angular distributions of incident sunlight, which in turn depend on surface orientation, solar position and atmospheric conditions. A widely used solar reflectance metric based on the ASTM Standard E891 beam-normal solar spectral irradiance underestimates the solar heat gain of a spectrally selective 'cool colored' surface because this irradiance contains a greater fraction of near-infrared light than typically found in ordinary (unconcentrated) global sunlight. At mainland U.S. latitudes, this metric RE891BN can underestimate the annual peak solar heat gain of a typical roof or pavement (slope {le} 5:12 [23{sup o}]) by as much as 89 W m{sup -2}, and underestimate its peak surface temperature by up to 5 K. Using R{sub E891BN} to characterize roofs in a building energy simulation can exaggerate the economic value N of annual cool-roof net energy savings by as much as 23%. We define clear-sky air mass one global horizontal ('AM1GH') solar reflectance R{sub g,0}, a simple and easily measured property that more accurately predicts solar heat gain. R{sub g,0} predicts the annual peak solar heat gain of a roof or pavement to within 2 W m{sup -2}, and overestimates N by no more than 3%. R{sub g,0} is well suited to rating the solar reflectances of roofs, pavements and walls. We show in Part II that R{sub g,0} can be easily and accurately measured with a pyranometer, a solar spectrophotometer or version 6 of the Solar Spectrum Reflectometer.

Summit-Watertown transmission line project, South Dakota. Final Environmental Assessment  

SciTech Connect

The Western Area Power Administration (Western) needs to rebuild the existing Summit-Watertown 115-kV transmission line, located in northeastern South Dakota, and western Minnesota. Nearly 60 percent of the existing facility was replaced in 1965 after severe ice-loading broke structures and wires. Because of the extensive loss of the line, surplus poles had to be used to replace the damaged H-frame structures. These were of varying sizes, causing improper structure loading. Additionally, the conductors and overhead shield wires have been spliced in numerous places. This provides additional space on these wires for icing and wind resistance, which in turn create problems for reliability. Finally, a progressive fungal condition has weakened the poles and, along with the improper loading, has created an unsafe condition for maintenance personnel and the general public.

Integrating health impact assessment into the triple bottom line concept  

SciTech Connect

This theoretical study explores the links between the Triple Bottom Line (TBL) concept and the principles of HIA and considers the potential role of HIA to provide a mechanism for integrating health concerns within a broader agenda of government and business. TBL is a framework linked to the broader sustainability agenda that underpins and reviews environmental, economic and social performance of organizations. In its simplest form, TBL acts as a tool for reporting to stakeholders/shareholders organizational performance and the nature of the impacts on the community. The links to HIA are clear as both seek to determine the impact (potential and actual) on the health and well-being of the population. The study found that TBL can operate at four levels within organizations ranging from reporting through to full integration with the organization's goals and practices. Health is narrowly defined and there are tensions about how to undertake the social accountability functions. The study shows the potential role for HIA within the broader policy and accountability agenda. As health is one of the main outcomes of an organization's activities it needs to be taken into account at all levels of activity.

The Contribution of Self-discrepancy in the Relationship between Role Loss and Well-being in Older Adults  

E-Print Network (OSTI)

The purpose of the study is to investigate how older adults adjust to getting older and the losses that come with aging. This study examines how E.T. Higgins's theory of self-discrepancy mediates the relationship between role loss and subjective well-being. Subjective well-being (SWB) is defined as overall life satisfaction, the presence of positive affect and the absence of negative affect. This hypothesis, grounded in both self-discrepancy and life span developmental theory, is that the level of discrepancy between the actual and ideal self mediates the relationship between role losses and mental health. This study examined three models with each investigating how self-discrepancy mediates the relationship between role loss and a different outcome variable for each model: positive affect, negative affect, and satisfaction with life. The sample consisted of adults over the age of 60 living in both community and institutional settings. Several path analyses models were run to examine the tenability of the hypotheses within the three models. This study did not support any of its hypotheses of the indirect and direct effects mediation models with the outcome variables of positive affect, negative affect and satisfaction with life scale. However, it did show support for the self-discrepancy theory. Consistent with the theory, this study showed that those reporting more self-discrepancy reported less satisfaction with life, less positive affect, and more negative affect. This study also showed levels of SWB in non-clinical samples of older adults. This study supported the idea that more self-discrepancy is related to lower levels of SWB. This is important in a clinical setting to know for treatment of older adults suggesting that clinicians help their clients work towards less self-discrepancy and in turn, greater SWB.

100-N temporary construction line considerations  

SciTech Connect

Present thinking and planning appears to be developing from the following factors as concern the 13.8 KV temporary construction power limit. 1. It is understood that the present intent is to supply 100-N operating requirements from a single stub source in the 230 KV loop. 2. The original thoughts were to obtain construction power over a 13.8 KV line from 151-D substation. 3. Construction load requirements are now less than originally planned since steam has been substituted for electrical drive of primary loop pumps and 5500 hp motor tests are no longer necessary. 4. An extreme emergency backup source for the K plants has always been of concern, although minimized in recent planning. It is desirable to review the temporary construction line requirements from a future operating viewpoint to determine if the line could be useful to the operating plants after completion of construction. It is highly desirable to provide T.C. power source from K plants rather than 151-D and then leave the line and breakers in place for future maintenance assistance and as extreme emergency backup to K plants.

An Economic Analysis of Agricultural Soil Loss in Mitchell County, Texas  

E-Print Network (OSTI)

The Federal Water Pollution Control Act Amendments of 1972, Public Law 92-500, established a national goal of eliminating the discharge of pollutants into the nation's waterways by 1985. As a step toward that goal an interim water quality standard of "fishable, swimmable waters nationwide" by July 1, 1983 was set. Under section 208 of this law, each state was required to establish a "continuing planning process" to define controls for agricultural nonpoint sources of water pollution. Section 208 calls for the development of state and area-wide water quality management plans. The plans are to include "a process to (i) identify if appropriate, agriculturally and silviculturally related non-point sources of pollution, including runoff from manure disposal areas, and from land used for livestock and crop production, and (ii) set forth procedures and methods (including land use requirements) to control to the extent feasible such sources." In an earlier group of technical reports (TR 87, 88, 90, 93) in this series a model was developed to measure the net social benefits from controlling agricultural sediment given various policy options. This was done by contrasting benefits to be gained from reducing the sediment load in a watershed against costs involved in achieving that reduction using various voluntary or mandatory policies to accomplish the reduction. It was a major conclusion of these studies that no policy that restricted soil loss to less than that which was economically desirable from the farmers own viewpoint would generate benefits greater than the costs involved. This finding, in the watersheds of major sediment control concern lead to a decision to change the base area for this report to a county instead of a watershed and to only deal with the on-farm consequences of various management practices. These on-farm consequences would include the changes in topsoil loss and the yield losses that result from losing topsoil. Also included are profit levels that could be expected from different management practices and how the present value of a stream of these profits would vary over different planning horizons.

Developing a CD-CBM Anticipatory Approach for Cavitation - Defining a Model Descriptor Consistent Between Processes  

Science Conference Proceedings (OSTI)

A major problem with cavitation in pumps and other hydraulic devices is that there is no effective method for detecting or predicting its inception. The traditional approach is to declare the pump in cavitation when the total head pressure drops by some arbitrary value (typically 3o/0) in response to a reduction in pump inlet pressure. However, the pump is already cavitating at this point. A method is needed in which cavitation events are captured as they occur and characterized by their process dynamics. The object of this research was to identify specific features of cavitation that could be used as a model-based descriptor in a context-dependent condition-based maintenance (CD-CBM) anticipatory prognostic and health assessment model. This descriptor was based on the physics of the phenomena, capturing the salient features of the process dynamics. An important element of this concept is the development and formulation of the extended process feature vector @) or model vector. Thk model-based descriptor encodes the specific information that describes the phenomena and its dynamics and is formulated as a data structure consisting of several elements. The first is a descriptive model abstracting the phenomena. The second is the parameter list associated with the functional model. The third is a figure of merit, a single number between [0,1] representing a confidence factor that the functional model and parameter list actually describes the observed data. Using this as a basis and applying it to the cavitation problem, any given location in a flow loop will have this data structure, differing in value but not content. The extended process feature vector is formulated as follows: E`> [ , {parameter Iist}, confidence factor]. (1) For this study, the model that characterized cavitation was a chirped-exponentially decaying sinusoid. Using the parameters defined by this model, the parameter list included frequency, decay, and chirp rate. Based on this, the process feature vector has the form: @=> [, {01 = a, ~= b, ~ = c}, cf = 0.80]. (2) In this experiment a reversible catastrophe was examined. The reason for this is that the same catastrophe could be repeated to ensure the statistical significance of the data.
