HydroPulse Drilling  

Science Conference Proceedings (OSTI)

Tempress HydroPulse{trademark} tool increases overbalanced drilling rates by generating intense suction pulses at the drill bit. This report describes the operation of the tool; results of pressure drilling tests, wear tests and downhole drilling tests; and the business case for field applications. The HydroPulse{trademark} tool is designed to operate on weighted drilling mud at conventional flow rates and pressures. Pressure drilling tests confirm that the HydroPulse{trademark} tool provides 33% to 200% increased rate of penetration. Field tests demonstrated conventional rotary and mud motor drilling operations. The tool has been operated continuous for 50 hours on weighted mud in a wear test stand. This level of reliability is the threshold for commercial application. A seismic-while-drilling version of the tool was also developed and tested. This tool was used to demonstrate reverse vertical seismic profiling while drilling an inclined test well with a PDC bit. The primary applications for the HydroPulse{trademark} tool are deep onshore and offshore drilling where rate of penetration drives costs. The application of the seismic tool is vertical seismic profiling-while-drilling and look-ahead seismic imaging while drilling.

Lifting hydro's potential  

Science Conference Proceedings (OSTI)

Electric utilities are taking another look at potential sites for hydroelectric installations, reevaluating sites that had been uneconomic to develop and those that can be renovated or expanded. Both large- and small-scale facilities now offer the advantages of free fuel, no air or thermal pollution, and no waste - making hydro an attractive way to increase utility capacity. The Electric Power Research Institute (EPRI) is participating in screening studies which evaluate the unique characteristics of specific sites and recommend technical improvements for better water control and a higher output. Pumped-hydro facilities are increasing, with new attention going to underground storage as new aboveground sites become harder to find. The institutional hurdles of licensing and regulation, interference with recreational and shoreline activities, down-stream water temperature changes, fish migration, and insurance are often in conflict. EPRI's screening program includes a simplified cost/benefit analysis and a site characterization, which utilities can use for their evaluation. Future research will explore a new financing arrangement that will lower front-end costs. (DCK)

A new method for stochastic production simulation in generation system with multiple hydro units  

SciTech Connect

This paper describes a new method of calculating loss of load probability, expected energy generation and production cost for units in a generating system with multiple hydro units. The method uses the equivalent load duration curve (ELDC) obtained by convolving the distributions of the original load and the forced outage power loss of all generators. Hydro units are scheduled on the ELDC according to their assigned energy and available capacity. Then the deconvolution procedure is performed to obtain a load duration curve for an equivalent system without hydro units. The expected energy of the thermal units is achieved by convolving the generating units in an economic merit order of loading.

E-Print Network (OSTI)

A new cosmological multidimensional hydrodynamic and N-body code based on an Adaptive Mesh Refinement scheme is described and tested. The hydro part is based on modern high-resolution shock-capturing techniques, whereas N-body approach is based on the Particle Mesh method. The code has been specifically designed for cosmological applications. Tests including shocks, strong gradients, and gravity have been considered. A cosmological test based on Santa Barbara cluster is also presented. The usefulness of the code is discussed. In particular, this powerful tool is expected to be appropriate to describe the evolution of the hot gas component located inside asymmetric cosmological structures.

Fundamental economic issues in the development of small scale hydro  

DOE Green Energy (OSTI)

Some basic economic issues involved in the development of small-scale hydroelectric power are addressed. The discussion represents an economist's view of the investment process in this resource. Very little investment has been made in small-scale hydro development and an attempt is made to show that the reason for this may not be that the expected present worth of the returns of the project do not exceed the construction cost by a sufficient amount. Rather, a set of factors in combination impose costs on the project not normally incurred in small businesses. The discussion covers costs, supply, demand, and profitability.

Ontario Hydro Motor Efficiency Study  

E-Print Network (OSTI)

Electric motors consume more than one-half of the electrical energy produced by Ontario Hydro. In the residential sector, the major motor load is for refrigerators and freezers while packaged equipment dominate the motor load in the commercial market. However, this paper concentrates on the industrial market since 76% of this market's load is motors. The poly phase integral horsepower motor is the "workhorse" of industry. The efficiency of the standard induction motor can be improved. The new "high efficiency" motor is described and the operating cost is compared to the standard motor. Payback for high efficiency motors is found to be about one year for continuous duty applications. Specific instructions are presented for use in industry.

Fresh Look at Weather Impact on Peak Electricity Demand and Energy Use of Fresh Look at Weather Impact on Peak Electricity Demand and Energy Use of Buildings Using 30-Year ActualWeather Data Title A Fresh Look at Weather Impact on Peak Electricity Demand and Energy Use of Buildings Using 30-Year ActualWeather Data Publication Type Journal Year of Publication 2013 Authors Hong, Tianzhen, Wen-Kuei Chang, and Hung-Wen Lin Keywords Actual meteorological year, Building simulation, Energy use, Peak electricity demand, Typical meteorological year, Weather data Abstract Buildings consume more than one third of the world's total primary energy. Weather plays a unique and significant role as it directly affects the thermal loads and thus energy performance of buildings. The traditional simulated energy performance using Typical Meteorological Year (TMY) weather data represents the building performance for a typical year, but not necessarily the average or typical long-term performance as buildings with different energy systems and designs respond differently to weather changes. Furthermore, the single-year TMY simulations do not provide a range of results that capture yearly variations due to changing weather, which is important for building energy management, and for performing risk assessments of energy efficiency investments. This paper employs large-scale building simulation (a total of 3162 runs) to study the weather impact on peak electricity demand and energy use with the 30-year (1980 to 2009) Actual Meteorological Year (AMY) weather data for three types of office buildings at two design efficiency levels, across all 17 ASHRAE climate zones. The simulated results using the AMY data are compared to those from the TMY3 data to determine and analyze the differences. Besides further demonstration, as done by other studies, that actual weather has a significant impact on both the peak electricity demand and energy use of buildings, the main findings from the current study include: 1) annual weather variation has a greater impact on the peak electricity demand than it does on energy use in buildings; 2) the simulated energy use using the TMY3 weather data is not necessarily representative of the average energy use over a long period, and the TMY3 results can be significantly higher or lower than those from the AMY data; 3) the weather impact is greater for buildings in colder climates than warmer climates; 4) the weather impact on the medium-sized office building was the greatest, followed by the large office and then the small office; and 5) simulated energy savings and peak demand reduction by energy conservation measures using the TMY3 weather data can be significantly underestimated or overestimated. It is crucial to run multi-decade simulations with AMY weather data to fully assess the impact of weather on the long-term performance of buildings, and to evaluate the energy savings potential of energy conservation measures for new and existing buildings from a life cycle perspective.

The Impact of Residential Air Conditioner Charging and Sizing on Peak Electrical Demand  

E-Print Network (OSTI)

Electric utilities have had a number of air conditioner rebate and maintenance programs for many years. The purpose of these programs was to improve the efficiency of the stock of air conditioning equipment and provide better demand-side management. This paper examines the effect of refrigerant charging (proper servicing of the equipment), system sizing, and efficiency on the steady-state, coincident peak utility demand of a residential central air conditioning system. The study is based on the results of laboratory tests of a three-ton, capillary tube expansion, split-system air conditioner, system capacity and efficiency data available from manufacturer's literature, and assumptions about relative sizing of the equipment to cooling load on a residence. A qualitative discussion is provided concerning the possible impacts of transient operation and total energy use on utility program decisions. The analysis indicates that proper sizing of the unit is the largest factor affecting energy demand of the three factors (sizing, charging, and efficiency) studied in this paper. For typical oversizing of units to cooling loads in houses, both overcharging and undercharging showed significant negative impact on peak demand. The impacts of SEER changes in utility peak demand were found to be virtually independent of oversizing. For properly sized units, there was a small peak benefit to higher efficiency air conditioners.

Distillate Stocks Expected  

Gasoline and Diesel Fuel Update (EIA)

4 4 Notes: So let's get to what you want to know. What do we expect this upcoming winter? When EIA's demand forecast is combined with its outlook for production and net imports, distillate stocks are projected to remain towards the lower end of the normal range. We are forecasting about an 11 million barrel build between the end of July 2001 and the end of November 2001, slightly more than the average over the past 5 years (10 million barrels), but less than the average of the last 10 years (15 ½ million barrels). If, however, economic incentives are high enough, distillate stocks could build more, resulting in a higher distillate stock level heading into the winter. Of course, the reverse is true as well, if for example, the distillate fuel refining spread declines substantially. Since 1994,

Groundwater Data Modeling for Arc Hydro  

E-Print Network (OSTI)

During the years 19992002, a consortium for geographic information systems (GIS) in water resources, led by the Center for Research in Water Resources (CRWR) and the Environmental Systems Research Institute (ESRI), developed a data model, named Arc Hydro, for the presentation of surface water data in ArcGIS. This model was published in the summer of 2002 (Maidment, 2002) and has since been adopted as a common framework by data producing agencies, such as the USGS, and by creators of hydrologic models requiring GIS data such as the Hydrologic Engineering Center and the Danish Hydraulic Institute. The Design of Arc Hydro revealed that it is possible to define a hydrologic information system which is a synthesis of geospatial and temporal data supporting hydrologic analysis and modeling (Maidment, 2002). This is an exciting new concept because rather than simply applying GIS in water resources, it provides a new way of thinking about how information technology can be used to support water resources planning, modeling and management. While the first Arc Hydro data model focused on describing surface water behavior, it has become apparent that a similar effort is needed to define an ArcGIS data model for groundwater, as part of Arc Hydro. This need is emphasized by the lack of a well understood and generally agreed

[Hydro-Quebec]: Annual report, 1998  

SciTech Connect

Hydro Quebec is a publicly owned utility constituted by an Act of the Quebec Legislative Assembly in April 1944. In 1981, it became a joint stock company with a single shareholder: The Quebec government. It generates, transmits and distributes almost all the electricity consumed in Quebec and also sells and purchases both energy and power under agreement with neighboring systems in Canada and the United States. The annual report discusses the year's activities, and includes a financial review, financial statements and a five-year review, a list of the Board of Directors and senior management, descriptions of subsidiaries and affiliates and statistics covering the power system.

The development of a charge protocol to take advantage of off- and on-peak demand economics at facilities  

DOE Green Energy (OSTI)

This document reports the work performed under Task 1.2.1.1: 'The development of a charge protocol to take advantage of off- and on-peak demand economics at facilities'. The work involved in this task included understanding the experimental results of the other tasks of SOW-5799 in order to take advantage of the economics of electricity pricing differences between on- and off-peak hours and the demonstrated charging and facility energy demand profiles. To undertake this task and to demonstrate the feasibility of plug-in hybrid electric vehicle (PHEV) and electric vehicle (EV) bi-directional electricity exchange potential, BEA has subcontracted Electric Transportation Applications (now known as ECOtality North America and hereafter ECOtality NA) to use the data from the demand and energy study to focus on reducing the electrical power demand of the charging facility. The use of delayed charging as well as vehicle-to-grid (V2G) and vehicle-to-building (V2B) operations were to be considered.

Methodology for Costing Ancillary Services from Hydro Resources  

Science Conference Proceedings (OSTI)

Due to the unique flexibility of Hydro resources, Hydro resource owners perceive a unique opportunity to profit from emerging markets for Ancillary Services (A/S) service products. Effective pricing and profitability measurement tools, however, are not widely available. This report creates a framework for defining A/S products and develops a methodology for calculating total incremental costs of providing A/S in terms of five cost elements.

3-D hydro + cascade model at RHIC  

E-Print Network (OSTI)

We present a 3-D hydro + cascade model, in which viscosity and a realistic freezeout process for the hadronic phase are taken into account. We compare our results to experimental data and discuss the final state interaction effects on physical observables. 1. FREEZEOUT PROCESS AND VISCOSITY IN HYDRODYNAMICS Hydrodynamic models have been very successful in describing the collective behavior of matter at RHIC, such as single particle spectra and elliptic flow. In particular the strong elliptic flow which, for the first time, reaches the hydrodynamic limit at RHIC, provides us with a new understanding of the nature of the quark-gluon plasma (QGP) created at RHIC as strongly interacting or correlated QGP [ 1]. However there exist a number of experimental observations that contradict ideal hydrodynamic models: transverse momentum spectra above 2 GeV, elliptic flow at large pseudo-rapdities ? and Hanbury Brown- Twiss (HBT) interferometry. These observations suggest that there exist limitations to the application of a simple ideal hydrodynamic model to RHIC physics and that an improvement on an ideal hydrodynamic model is needed in order to obtain a comprehensive and unified description of the data from the point of view of hydrodynamics. In general, hydrodynamic models require initial conditions, an equations of state (EoS)

Evolving Einstein's Field Equations with Matter: The ``Hydro without Hydro'' Test  

E-Print Network (OSTI)

We include matter sources in Einstein's field equations and show that our recently proposed 3+1 evolution scheme can stably evolve strong-field solutions. We insert in our code known matter solutions, namely the Oppenheimer-Volkoff solution for a static star and the Oppenheimer-Snyder solution for homogeneous dust sphere collapse to a black hole, and evolve the gravitational field equations. We find that we can evolve stably static, strong-field stars for arbitrarily long times and can follow dust sphere collapse accurately well past black hole formation. These tests are useful diagnostics for fully self-consistent, stable hydrodynamical simulations in 3+1 general relativity. Moreover, they suggest a successive approximation scheme for determining gravitational waveforms from strong-field sources dominated by longitudinal fields, like binary neutron stars: approximate quasi-equilibrium models can serve as sources for the transverse field equations, which can be evolved without having to re-solve the hydrodynamical equations (``hydro without hydro'').

Papua New Guinea plans for more hydro power  

SciTech Connect

Papua New Guinea is one of the world's last reserves of untapped hydro power, but the needs of the country's isolated utility systems are comparatively small. The government has recently unveiled a study, based on an 8% annual growth rate, which defines the opportunities for hydro development in the next decade. The Electricity Commission of Papua New Guinea is carrying out a province-by-province survey of potential for comparatively low-cost small-scale hydro deveopment, which can form the basis of provincial electrification in areas that cannot be reached by network distribution lines from the Ramu Valley or Port Mores by hydro grids. Funding for these projects has already been approved. The program for the ten-year power development plan 1978 to 1987 incudes the Port Moresby and Ramu service areas, East New Britain, Wewak and Kavieng, and other provinces. The big projects included in the program are all hydro schemes: Upper Warangoi No. 1 and 2, Rouna 4, Daugel, and Angabunga. Specifically, the Port Moresby System, the Ramu Service Area, and Rabaul/Kerevat/Warangoi System are discussed. (MCW)

North Dome decision expected soon  

Science Conference Proceedings (OSTI)

Decisions soon will be made which will set in motion the development of Qatar's huge North Dome gas field. The government and state company, Qatar General Petroleum Corp. (QGPC) is studying the results of 2 feasibility studies on the economics of LNG export, although initially North Dome exploitation will be aimed at the domestic market. Decisions on the nature and timing of the North Dome development are the most important that have had to be faced in the short 10-yr history of the small Gulf state. The country's oil production is currently running at approximately 500,000 bpd, with 270,000 bpd originating from 3 offshore fields. Output is expected to decline through 1990, and it generally is accepted that there is little likelihood of further major crude discoveries. Therefore, Qatar has to begin an adjustment from an economy based on oil to one based on gas, while adhering to the underlying tenets of long-term conservation and industrial diversification.

Laotian hydro scheme will supply Thailand  

SciTech Connect

Transmission lines between Laos and Thailand are being strengthened to allow Thailand the opportunity to benefit from the surplus power of the Nam Ngum hydroelectric project. Phase 2 of the project has increased capacity beyond expected Laotian demand in order to develop a long-term economic program of sales to Thailand, which can use the energy as a fuel replacement. Agreements of the Electric Generating Authority of Thailand (EGAT) and Electrite du Laos (EdL) specify sales at the rate of $4.50 per megawatt hour, with a mutual option to renew after ten years. Rural electrification, fisheries, and flood control benefits for Laos will add to the possibilities for economic development. Details are given in the article for the expansion and costs of the powerhouse, reservoirs, and transmission equipment. (DCK)

Hydro-kinetic approach to relativistic heavy ion collisions  

E-Print Network (OSTI)

We develop a combined hydro-kinetic approach which incorporates hydrodynamical expansion of the systems formed in \\textit{A}+\\textit{A} collisions and their dynamical decoupling described by escape probabilities. The method corresponds to a generalized relaxation time ($\\tau_{\\text{rel}}$) approximation for Boltzmann equation applied to inhomogeneous expanding systems; at small $\\tau_{\\text{rel}}$ it also allows one to catch the viscous effects in hadronic component - hadron-resonance gas. We demonstrate how the approximation of sudden freeze-out can be obtained within this dynamical picture of continuous emission and find that hypersurfaces, corresponding to sharp freeze-out limit, are momentum dependent. The pion $m_{T}$ spectra are computed in the developed hydro-kinetic model, and compared with those obtained from ideal hydrodynamics with the Cooper-Frye isothermal prescription. Our results indicate that there does not exist a universal freeze-out temperature for pions with different momenta, and support ...

Modeling hydro power plants in deregulated electricity markets : integration and application of EMCAS and VALORAGUA.  

Science Conference Proceedings (OSTI)

In this paper, we present details of integrating an agent-based model, Electricity Market Complex Adaptive System (EMCAS) with a hydro-thermal coordination model, VALORAGUA. EMCAS provides a framework for simulating deregulated markets with flexible regulatory structure along with bidding strategies for supply offers and demand bids. VALORAGUA provides longer-term operation plans by optimizing hydro and thermal power plant operation for the entire year. In addition, EMCAS uses the price forecasts and weekly hydro schedules from VALORAGUA to provide intra-week hydro plant optimization for hourly supply offers. The integrated model is then applied to the Iberian electricity market which includes about 111 thermal plants and 38 hydro power plants. We then analyze the impact of hydro plant supply offers on the market prices and ways to minimize the Gencospsila exposure to price risk.

Role of Pumped Storage Hydro Resources in Electricity Markets and System Operation: Preprint  

DOE Green Energy (OSTI)

The most common form of utility- sized energy storage system is the pumped storage hydro system. Originally, these types of storage systems were economically viable simply because they displace more expensive generating units. However, over time, as those expensive units became more efficient and costs declined, pumped hydro storage units no longer have the operational edge. As a result, in the current electricity market environment, pumped storage hydro plants are struggling. To offset this phenomenon, certain market modifications should be addressed. This paper will introduce some of the challenges faced by pumped storage hydro plants in today's markets and purpose some solutions to those problems.

Pion correlations in hydro-inspired models with resonances  

E-Print Network (OSTI)

The effects of the freeze-out hypersurface and resonance decays on the pion correlation functions in relativistic heavy-ion collisions are studied with help of the hydro-inspired models with single freeze-out. The heavy-ion Monte-Carlo generator THERMINATOR is used to generate hadronic events describing production of particles from a thermalized and expanding source. We find that the short-lived resonances increase the pionic HBT radii by about 1 fm. We also find that the pion HBT data from RHIC are fully compatible with the single freeze-out scenario provided a special choice of the freeze-out hypersurface is made.

A comparative analysis of accident risks in fossil, hydro, and nuclear energy chains  

Science Conference Proceedings (OSTI)

This study presents a comparative assessment of severe accident risks in the energy sector, based on the historical experience of fossil (coal, oil, natural gas, and LPG (Liquefied Petroleum Gas)) and hydro chains contained in the comprehensive Energy-related Severe Accident Database (ENSAD), as well as Probabilistic Safety Assessment (PSA) for the nuclear chain. Full energy chains were considered because accidents can take place at every stage of the chain. Comparative analyses for the years 1969-2000 included a total of 1870 severe ({>=} 5 fatalities) accidents, amounting to 81,258 fatalities. Although 79.1% of all accidents and 88.9% of associated fatalities occurred in less developed, non-OECD countries, industrialized OECD countries dominated insured losses (78.0%), reflecting their substantially higher insurance density and stricter safety regulations. Aggregated indicators and frequency-consequence (F-N) curves showed that energy-related accident risks in non-OECD countries are distinctly higher than in OECD countries. Hydropower in non-OECD countries and upstream stages within fossil energy chains are most accident-prone. Expected fatality rates are lowest for Western hydropower and nuclear power plants; however, the maximum credible consequences can be very large. Total economic damages due to severe accidents are substantial, but small when compared with natural disasters. Similarly, external costs associated with severe accidents are generally much smaller than monetized damages caused by air pollution.

L'utilisation des hydro-jecteurs au CERN  

E-Print Network (OSTI)

Les jecteurs buse variable sont destins remplacer les vannes trois voies conventionnelles et les pompes secondaires de circulation dans les installations de chauffage eau chaude et de conditionnement d'air. Ces jecteurs liquide - liquide utilisent l'nergie d'un fluide primaire pour maintenir le dbit d'un fluide secondaire grce un saut de pression. L'utilisation de ces jecteurs permet notamment de rduire les co ts d'investissement, de consommation nergtique et aussi de maintenance. Cette technique qui a fait ses preuves depuis plus de 20 ans, est abondamment utilise en Allemagne, Italie et Belgique (50 000 boucles) et peu dans d'autres pays comme la France (500 boucles). Au CERN, aucune application d'hydro-jecteur de ce type n'a encore t mise en oeuvre ce jour.

Bentonite alteration due to thermal-hydro-chemical processes during the early thermal period in a nuclear waste repository  

SciTech Connect

After closure of an underground nuclear waste repository, the decay of radionuclides will raise temperature in the repository, and the bentonite buffer will resaturate by water inflow from the surrounding host rock. The perturbations from these thermal and hydrological processes are expected to dissipate within hundreds to a few thousand years. Here, we investigate coupled thermal-hydro-chemical processes and their effects on the short-term performance of a potential nuclear waste repository located in a clay formation. Using a simplified geometric configuration and abstracted hydraulic parameters of the clayey formation, we examine geochemical processes, coupled with thermo-hydrologic phenomena, and potential changes in porosity near the waste container during the early thermal period. The developed models were used for evaluating the mineral alterations and potential changes in porosity of the buffer, which can affect the repository performance. The results indicate that mineral alteration and associated changes in porosity induced by early thermal and hydrological processes are relatively small and are expected to not significantly affect flow and transport properties. Chlorite precipitation was obtained in all simulation cases. A maximum of one percent volume fraction of chlorite could be formed, whose process may reduce swelling and sorption capacity of bentonite clay, affecting the performance of the repository. llitisation process was not obtained from the present simulations.

Hydro-Gravitational-Dynamics of Planets and Dark Energy

Moderate accretion rates produce white dwarfs that evaporate surrounding gas planets by spin-radiation to form planetary nebulae before Supernova Ia events, dimming some events to give systematic distance errors misinterpreted as the dark energy hypothesis and overestimates of the universe age. Failures of standard LCDM cosmological models reflect not only obsolete Jeans 1902 fluid mechanical assumptions, but also failures of standard turbulence models that claim the cascade of turbulent kinetic energy is from large scales to small. Because turbulence is always driven at all scales by inertial-vortex forces the turbulence cascade is always from small scales to large.

Hydrogen Resource Assessment: Hydrogen Potential from Coal, Natural Gas, Nuclear, and Hydro Power  

DOE Green Energy (OSTI)

This paper estimates the quantity of hydrogen that could be produced from coal, natural gas, nuclear, and hydro power by county in the United States. The study estimates that more than 72 million tonnes of hydrogen can be produced from coal, natural gas, nuclear, and hydro power per year in the country (considering only 30% of their total annual production). The United States consumed about 396 million tonnes of gasoline in 2007; therefore, the report suggests the amount of hydrogen from these sources could displace about 80% of this consumption.

A Hydro-mechanical Model and Analytical Solutions for Geomechanical Modeling of Carbon Dioxide Geological Sequestration  

SciTech Connect

We present a hydro-mechanical model for geological sequestration of carbon dioxide. The model considers the poroelastic effects by taking into account the coupling between the geomechanical response and the fluid flow in greater detail. The simplified hydro-mechanical model includes the geomechanical part that relies on the linear elasticity, while the fluid flow is based on the Darcys law. Two parts were coupled using the standard linear poroelasticity. Analytical solutions for pressure field were obtained for a typical geological sequestration scenario. The model predicts the temporal and spatial variation of pressure field and effects of permeability and elastic modulus of formation on the fluid pressure distribution.

We have performed detailed NLTE spectral synthesis modeling of 2 types of 1-D hydro models: the very highly parameterized deflagration model W7, and two delayed detonation models. We find that overall both models do about equally well at fitting well observed SNe Ia near to maximum light. However, the Si II 6150 feature of W7 is systematically too fast, whereas for the delayed detonation models it is also somewhat too fast, but significantly better than that of W7. We find that a parameterized mixed model does the best job of reproducing the Si II 6150 line near maximum light and we study the differences in the models that lead to better fits to normal SNe Ia. We discuss what is required of a hydro model to fit the spectra of observed SNe Ia near maximum light.

Buda-Lund hydro model and the elliptic flow at RHIC  

E-Print Network (OSTI)

The ellipsoidally symmetric Buda-Lund hydrodynamic model describes naturally the transverse momentum and the pseudorapidity dependence of the elliptic flow in Au+Au collisions at $\\sqrt{s_{NN}} = 130$ and 200 GeV. The result confirms the indication of quark deconfinement in Au+Au collisions at RHIC, obtained from Buda-Lund hydro model fits to combined spectra and HBT radii of BRAHMS, PHOBOS, PHENIX and STAR.

Stochastic Lagrangian relaxation applied to power scheduling in a hydro-thermal system under uncertainty  

E-Print Network (OSTI)

A dynamic (multi-stage) stochastic programming model for the weekly cost-optimal generation of electric power in a hydro-thermal generation system under uncertain load is developed. The model involves a large number of mixed-integer (stochastic) decision variables and constraints linking time periods and operating power units. Astochastic Lagrangian relaxation scheme is designed by assigning (stochastic) multipliers to all constraints coupling power units. It is assumed that the stochastic load process is given (or approximated) by a nite number of realizations (scenarios) in scenario tree form. Solving the dual by a bundle subgradient method leads to a successive decomposition into stochastic single (thermal or hydro) unit subproblems. The stochastic thermal and hydro subproblems are solved by astochastic dynamic programming technique and by a speci c descent algorithm, respectively. A Lagrangian heuristics that provides approximate solutions for the rst stage (primal) decisions starting from the optimal (stochastic) multipliers is developed. Numerical results are presented for realistic data from a German power utility andfornumbers of scenarios ranging from 5 to 100 and a time horizon from 7 to 9 days. The sizes of the corresponding optimization problems go up to 200.000 binary and 350.000 continuous variables, and more than 500.000 constraints.

Boundary Conditions of the Hydro-Cascade Model and Relativistic Kinetic Equations for Finite Domains  

E-Print Network (OSTI)

A detailed analysis of the coupled relativistic kinetic equations for two domains separated by a hypersurface having both space- and time-like parts is presented. Integrating the derived set of transport equations, we obtain the correct system of the hydro+cascade equations to model the relativistic nuclear collision process. Remarkably, the conservation laws on the boundary between domains conserve separately both the incoming and outgoing components of energy, momentum and baryonic charge. Thus, the relativistic kinetic theory generates twice the number of conservation laws compared to traditional hydrodynamics. Our analysis shows that these boundary conditions between domains, the three flux discontinuity, can be satisfied only by a special superposition of two cut-off distribution functions for the ``out'' domain. All these results are applied to the case of the phase transition between quark gluon plasma and hadronic matter. The possible consequences for an improved hydro+cascade description of the relativistic nuclear collisions are discussed. The unique properties of the three flux discontinuity and their effect on the space-time evolution of the transverse expansion are also analyzed. The possible modifications of both transversal radii from pion correlations generated by a correct hydro+cascade approach are discussed.

Witnessing the construction/commissioning of a small hydro plant as the bank's engineer  

Science Conference Proceedings (OSTI)

Many small hydro sites today are constructed as water-to-wire packages with equipment installation {und and} engineering provided by the equipment vendor. In many cases; the client has no immediate knowledge of the design/engineering associated with a hydropower facility; and is enticed by the equipment vendor to believe that the involvement of outside engineering firms is an unnecessary extra cost. Fortunately, most clients employ an outside engineering firm to confirm that the equipment the vendor is furnishing does comply with the client's equipment specifications and will function properly at this specific site. The author discusses how most banks which provide the financing for a hydro project currently hire their own hydro engineering firm to separately review the final equipment specifications, the site construction progress and the quality of construction at site. This separate review is to ensure the bank that the unit has been constructed properly and will be commissioned on time, notify the bank in a very timely manner that there are construction problems/commissioning delays, and confirm that the unit will produce its guaranteed kW output.

On uncertainties associated with expected backgrounds in planned experiments  

SciTech Connect

The expected numbers of events of several backgrounds in experiment are estimated from Monte Carlo experiments. In the analysis we take into account an integrated luminosity of Monte Carlo experiments. The expected number of events allows to construct the distribution of probabilities of number of events which in real experiment may be observed (in accordance with formulae in [1]). The formulae allow to take into account statistical uncertainty of corresponding Monte Carlo experiment. The influence of systematics is determined by additional Monte Carlo experiments with expected number of events.

A new opportunity for hydro: Using air turbines for generating electricity  

SciTech Connect

A concept that uses hydropower to compress air could increase the number of locations where hydro is economically and environmentally feasible. The idea is being tested in a demonstration project in the northeastern U.S. The hydroelectric industry could experience substantial growth in low-head hydro facilities if a concept now being developed proves successful. This concept aims to enable power developers to generate electricity economically at sites currently not feasible for hydropower because water heads are too low. Many areas of North America are studded with low-head dams that could provide considerable hydro capacity if low-head generation were economically feasible. The six New England states in the US, for example, contain approximately 15,000 dams that have never been used to generate electric power because they impound water with heads ranging from 3 to 13 feet. Conventional facilities are not economically practical for generating electricity at these low heads. However, a promising alternative approach is to use water at these low-head dams to compress air, and then to use the air to power an air turbine-generator that produces electricity. The concept, called hydropneumatic generation, can be visualized by imagining a container, such as a large teacup, inverted and submerged in tidal waters. As the tide rises, the water compresses the air trapped inside the container. When the tide ebbs, the pressure decreases, putting the air into a partial vacuum. If a vent pipe were installed from the container to the atmosphere, air would flow out of the container as the water depth increased, and flow back in as the water depth decreased. Hydropneumatic energy is generated by installing an air-powered turbine to harness the energy of this airflow through the vent pipe. The turbine can be installed to rotate in the same direction at all times, even though the airflow reverses direction.

Evaluation of Blade-Strike Models for Estimating the Biological Performance of Large Kaplan Hydro Turbines  

DOE Green Energy (OSTI)

BioIndex testing of hydro-turbines is sought as an analog to the hydraulic index testing conducted on hydro-turbines to optimize their power production efficiency. In BioIndex testing the goal is to identify those operations within the range identified by Index testing where the survival of fish passing through the turbine is maximized. BioIndex testing includes the immediate tailrace region as well as the turbine environment between a turbine's intake trashracks and the exit of its draft tube. The US Army Corps of Engineers and the Department of Energy have been evaluating a variety of means, such as numerical and physical turbine models, to investigate the quality of flow through a hydro-turbine and other aspects of the turbine environment that determine its safety for fish. The goal is to use these tools to develop hypotheses identifying turbine operations and predictions of their biological performance that can be tested at prototype scales. Acceptance of hypotheses would be the means for validation of new operating rules for the turbine tested that would be in place when fish were passing through the turbines. The overall goal of this project is to evaluate the performance of numerical blade strike models as a tool to aid development of testable hypotheses for bioIndexing. Evaluation of the performance of numerical blade strike models is accomplished by comparing predictions of fish mortality resulting from strike by turbine runner blades with observations made using live test fish at mainstem Columbia River Dams and with other predictions of blade strike made using observations of beads passing through a 1:25 scale physical turbine model.

The centrality dependence of v2/epsilon: the ideal hydro limit and eta/s  

E-Print Network (OSTI)

The large elliptic flow observed at RHIC is considered to be evidence for almost perfect liquid behavior of the strongly coupled quark-gluon plasma produced in the collisions. In these proceedings we present a two parameter fit for the centrality dependence of the elliptic flow scaled by the spatial eccentricity. We show by comparing to viscous hydrodynamical calculations that these two parameters are in good approximation proportional to the shear viscosity over entropy ratio and the ideal hydro limit of the ratio v2/epsilon.

Yield and grain quality maps have been produced at full-scale field trials within a 10.5 ha field for four different nitrogen strategies. Grain samples have been collected directly from the grain flow of a combine harvester and analysed for quality in the laboratory and merged with the yield meter registrations. Within the field great variance was observed in yield and grain quality. This paper evaluates the impact on yield and grain quality -- protein when nitrogen is sensor applied by the Hydro-Precise N-Sensor system. The results are discussed in terms of a potential new precision nitrogen application strategy for Danish winter wheat

An Optimization-Based Algorithm for Scheduling Hydrothermal Power Systems with Cascaded Reservoirs and Discrete Hydro Constraints  

E-Print Network (OSTI)

An optimization-based algorithm is presented for the short-term scheduling of hydrothermal power systems using the Lagrangian relaxation technique. This paper concentrates on the solution methodology for hydro subproblems with cascaded reservoirs and discrete hydro constraints. Continuous reservoir dynamics and constraints, discontinuous operating regions, discrete operating states, and hydraulic coupling of cascaded reservoirs are considered in an integrated fashion. The key idea is to substitute out the reservoir dynamics and to relax the reservoir level constraints by using another set of multipliers, making a hydro subproblem unit-wise and stage-wise decomposable. The optimal generation level for each operating state at each hour can be obtained simply by minimizing a single variable function. Dynamic programming is then applied to optimize the operating states across the planning horizon with a small number of well-structured transitions. A modified subgradient algorithm is used...

An Integrated Approach for Optimal Coordination of Wind Power and Hydro Pumping Storage  

E-Print Network (OSTI)

The increasing wind power penetration in power systems represents a techno-economic challenge for power producers and system operators. Due to the variability and uncertainty of wind power, system operators require new solutions in order to increase the controllability of wind farm output. On the other hand, producers that include wind farms in their portfolio need to find new ways to boost their profits in electricity markets. This can be done by optimizing the combination of wind farms and storage so as to make larger profits when selling power (trading) and reduce penalties from imbalances in the operation. The present work describes a new integrated approach for analyzing wind-storage solutions that make use of probabilistic forecasts and optimization techniques to aid decision-making on operating such systems. The approach includes a set of three complementary functions suitable for use in current systems. A reallife system is studied, comprising two wind farms and a large hydro station with pumping capacity. Economic profits and better operational features can be obtained from the proposed cooperation between the wind farms and storage. The revenues are function of the type of hydro storage used and the market characteristics and several options are compared in this study. The results show that the use of a storage device can lead to a significant increase in revenue, up to 11 % (2010 data, Iberian market). Also, the

Power management in a hydro-thermal system under uncertainty by Lagrangian relaxation  

E-Print Network (OSTI)

We present a dynamic multistage stochastic programming model for the cost-optimal generation of electric power in a hydro-thermal system under uncertainty in load, inflow to reservoirs and prices for fuel and delivery contracts. The stochastic load process is approximated by a scenario tree obtained by adapting a SARIMA model to historical data, using empirical means and variances of simulated scenarios to construct an initial tree, and reducing it by a scenario deletion procedure based on a suitable probability distance. Our model involves many mixed-integer variables and individual power unit constraints, but relatively few coupling constraints. Hence we employstochastic Lagrangian relaxation that assigns stochastic multipliers to the coupling constraints. Solving the Lagrangian dual by a proximal bundle method leads to successive decomposition into single thermal and hydro unit subproblems that are solved by dynamic programming and a specialized descent algorithm, respectively. The optimal stochastic multipliers are used in Lagrangian heuristics to construct approximately optimal first stage decisions. Numerical results are presented for realistic data from a German power utility, with a time horizon of one week and scenario numbers ranging from 5 to 100. The corresponding optimization problems have up to 200,000 binary and 350,000 continuous variables, and more than 500,000 constraints.

BETHE-Hydro: An Arbitrary Lagrangian-Eulerian Multi-dimensional Hydrodynamics Code for Astrophysical Simulations  

E-Print Network (OSTI)

In this paper, we describe a new hydrodynamics code for 1D and 2D astrophysical simulations, BETHE-hydro, that uses time-dependent, arbitrary, unstructured grids. The core of the hydrodynamics algorithm is an arbitrary Lagrangian-Eulerian (ALE) approach, in which the gradient and divergence operators are made compatible using the support-operator method. We present 1D and 2D gravity solvers that are finite differenced using the support-operator technique, and the resulting system of linear equations are solved using the tridiagonal method for 1D simulations and an iterative multigrid-preconditioned conjugate-gradient method for 2D simulations. Rotational terms are included for 2D calculations using cylindrical coordinates. We document an incompatibility between a subcell pressure algorithm to suppress hourglass motions and the subcell remapping algorithm and present a modified subcell pressure scheme that avoids this problem. Strengths of this code include a straightforward structure, enabling simple inclusion of additional physics packages, the ability to use a general equation of state, and most importantly, the ability to solve self-gravitating hydrodynamic flows on time-dependent, arbitrary grids. In what follows, we describe in detail the numerical techniques employed and, with a large suite of tests, demonstrate that BETHE-hydro finds accurate solutions with 2$^{nd}$-order convergence.

A numerical model of hydro-thermo-mechanical coupling in a fractured rock mass  

DOE Green Energy (OSTI)

Coupled hydro-thermo-mechanical codes with the ability to model fractured materials are used for predicting groundwater flow behavior in fractured aquifers containing thermal sources. The potential applications of such a code include the analysis of groundwater behavior within a geothermal reservoir. The capability of modeling hydro-thermo systems with a dual porosity, fracture flow model has been previously developed in the finite element code, FEHM. FEHM has been modified to include stress coupling with the dual porosity feature. FEHM has been further developed to implicitly couple the dependence of fracture hydraulic conductivity on effective stress within two dimensional, saturated aquifers containing fracture systems. The cubic law for flow between parallel plates was used to model fracture permeability. The Bartin-Bandis relationship was used to determine the fracture aperture within the cubic law. The code used a Newton Raphson iteration to implicitly solve for six unknowns at each node. Results from a model of heat flow from a reservoir to the moving fluid in a single fracture compared well with analytic results. Results of a model showing the increase in fracture flow due to a single fracture opening under fluid pressure compared well with analytic results. A hot dry rock, geothermal reservoir was modeled with realistic time steps indicating that the modified FEHM code does successfully model coupled flow problems with no convergence problems.

Conservation Laws for Coupled Hydro-mechanical Processes in Unsaturated Porous Media: Theory and Implementation  

Science Conference Proceedings (OSTI)

We develop conservation laws for coupled hydro-mechanical processes in unsaturated porous media using three-phase continuum mixture theory. From the first law of thermodynamics, we identify energy-conjugate variables for constitutive modeling at macroscopic scale. Energy conjugate expressions identified relate a certain measure of effective stress to the deformation of the solid matrix, the degree of saturation to the matrix suction, the pressure in each constituent phase to the corresponding intrinsic volume change of this phase, and the seepage forces to the corresponding pressure gradients. We then develop strong and weak forms of boundary-value problems relevant for 3D finite element modeling of coupled hydro-mechanical processes in unsaturated porous media. The paper highlights a 3D numerical example illustrating the advances in the solution of large-scale coupled finite element systems, as well as the challenges in developing more predictive tools satisfying the basic conservation laws and the observed constitutive responses for unsaturated porous materials.

LPB Hydro-Climate Variability as Simulated by GCM Experiments: Role of

LPB Hydro-Climate Variability as Simulated by GCM Experiments: Role of LPB Hydro-Climate Variability as Simulated by GCM Experiments: Role of Remote SST Forcing Title LPB Hydro-Climate Variability as Simulated by GCM Experiments: Role of Remote SST Forcing Publication Type Journal Article Year of Publication 2013 Authors Cherchi, A, Carril, AF, Zamboni, L, Menendez, C Journal Climate Dynamics Date Published 04/2012 Other Numbers ANL/MCS-P3016-0712 Abstract A set of AMIP-type experiments is computed and analyzed to study springtime hydro-climate variability in the region of La Plata Basin (LPB). In particular, an ensemble of nine experiments with same interannually varying SST, as boundary forcing, and different initial conditions is used to investigate the relative role of the Pacific, Indian and Atlantic tropical oceans on modulating the local precipitation. The AMIP type ensemble results have been compared with a coupled model experiment (using the same atmospheric component). The comparison reveals that the model has a good performance in the simulation of precipitation over LPB and South America, with a slight overestimation of the seasonal mean and an underestimation of the variability. Nevertheless, an EOF analysis of South America precipitation shows that the model is able to realistically reproduce the dominant modes of variability in spring. Further, its principal component (PC1) when correlated with global SST and atmospheric fields identifies the pattern related to ENSO and the large-scale connections. Overall the teleconnection pattern in the tropical and Southern Pacific Ocean is well captured by the SST-forced ensemble, but it is absent or too weak in other oceanic areas. In the subtropical South Atlantic the correlation is more realistic in the coupled model experiment suggesting the importance of air-sea feedbacks for that region, even at lower than interannual timescales. When the composite analysis of SST and atmospheric fields is done only over the ensemble members having a PC1 in agreement with the observations, both in terms of sign and intensity, then the correspondence between model and data is much improved. The improvement relies on avoiding climate noise by averaging only over members that are statistically similar and it suggests a high level of uncertainty due to internal atmospheric variability. Some individual springs have been analyzed as well. In particular, 1982 represents a clean case with a clear wave train propagating from the central Pacific and merging with a secondary one from eastern tropical South Indian Ocean, and it corresponds to a strong El Nino. Another case, 2003, corresponds to a rainy spring for SESA but in this case the en-semble mean does not exhibit any teleconnection through the South Pacific and it is not able to reproduce the correct local precipitation pattern, suggesting that in this case regional effects are more important than remote forcing.

Buda-Lund hydro model for ellipsoidally symmetric fireballs and the elliptic flow at RHIC  

E-Print Network (OSTI)

The ellipsoidally symmetric extension of Buda-Lund hydrodynamic model is shown here to yield a natural description of the pseudorapidity dependence of the elliptic flow $v_2(\\eta)$, as determined recently by the PHOBOS experiment for Au+Au collisions at $\\sqrt{s_{NN}} = 130$ and 200 GeV. With the same set of parameters, the Buda-Lund model describes also the transverse momentum dependence of $v_2$ of identified particles at mid-rapidity. The results confirm the indication for quark deconfinement in Au+Au collisions at RHIC, obtained from a successful Buda-Lund hydro model fit to the single particle spectra and two-particle correlation data, as measured by the BRAHMS, PHOBOS, PHENIX and STAR collaborations.

The objective is to maximize the profit of the company from selling energy in the day-ahead market. This paper proposes a 0/1 mixed-integer linear programming model to account, in every plant, for the nonlinear and nonconcave three-dimensional (3-D) relationship between the power produced, the water discharged, and the head of the associated reservoir. Additionally, start-up costs due mainly to the wear and tear are considered. Finally, different realistic case studies are analyzed in detail.

E-Print Network (OSTI)

This paper evaluates the central insight of the consumption capital asset pricing model that an assets expected return is determined by its equilibrium risk to consumption. Rather than measure risk by the contemporaneous covariance of an assets return and consumption growth, we measure risk by the covariance of an assets return and consumption growth cumulated over many quarters following the return. While contemporaneous consumption risk explains little of the variation in average returns across the 25 Fama-French portfolios, our measure of ultimate consumption risk at a horizon of three years explains a large fraction of this variation.

Self-Adjusting Networks to Minimize Expected Path Length  

E-Print Network (OSTI)

Given a network infrastructure (e.g., a grid, data-center or on-chip-network) and a distribution on the source-destination requests, the expected path (route) length is an important measure for the performance, efficiency and power consumption of the network. In this work we initiate a study on self-adjusting networks: networks that use local-distributed mechanisms to adjust the position of the nodes in the network to any distribution of route requests. Finding the optimal placement of nodes is defined as the minimum expected path length (MEPL) problem. While, as we show, the MEPL problem is NP-hard to solve exactly in general we give efficient and simple approximation algorithms for interesting and practically relevant special cases of the problem. E.g., we consider grid networks in which the distribution of requests is a symmetric product distribution. In this setting we show that simple greedy switches, which locally minimize an objective function, achieve good approximation ratios. We are able to prove th...

Analyzing Facebook privacy settings: User expectations vs. reality  

E-Print Network (OSTI)

The sharing of personal data has emerged as a popular activity over online social networking sites like Facebook. As a result, the issue of online social network privacy has received significant attention in both the research literature and the mainstream media. Our overarching goal is to improve defaults and provide better tools for managing privacy, but we are limited by the fact that the full extent of the privacy problem remains unknown; there is little quantification of the incidence of incorrect privacy settings or the difficulty users face when managing their privacy. In this paper, we focus on measuring the disparity between the desired and actual privacy settings, quantifying the magnitude of the problem of managing privacy. We deploy a survey, implemented as a Facebook application, to 200 Facebook users recruited via Amazon Mechanical Turk. We find that 36 % of content remains shared with the default privacy settings. We also find that, overall, privacy settings match users expectations only 37 % of the time, and when incorrect, almost always expose content to more users than expected. Finally, we explore how our results have potential to assist users in selecting appropriate privacy settings by examining the user-created friend lists. We find that these have significant correlation with the social network, suggesting that information from the social network may be helpful in implementing new tools for managing privacy.

Expected brine movement at potential nuclear waste repository salt sites  

SciTech Connect

The BRINEMIG brine migration code predicts rates and quantities of brine migration to a waste package emplaced in a high-level nuclear waste repository in salt. The BRINEMIG code is an explicit time-marching finite-difference code that solves a mass balance equation and uses the Jenks equation to predict velocities of brine migration. Predictions were made for the seven potentially acceptable salt sites under consideration as locations for the first US high-level nuclear waste repository. Predicted total quantities of accumulated brine were on the order of 1 m/sup 3/ brine per waste package or less. Less brine accumulation is expected at domal salt sites because of the lower initial moisture contents relative to bedded salt sites. Less total accumulation of brine is predicted for spent fuel than for commercial high-level waste because of the lower temperatures generated by spent fuel. 11 refs., 36 figs., 29 tabs.

An Expectation States Approach to Examining Medical Team Information Exchange  

E-Print Network (OSTI)

This project is the first step in a long line of research that will examine the impact of status on information exchange in small groups of medical professionals. Specifically, we employ the expectation states theory and observable power and prestige methodology to develop a coding scheme and live coding methodology that is attuned to the unique status organizing process in interprofessional medical teams. This paper begins with an explanation of the shortcomings in current research that examines medical teams. We then discuss the conceptual development of the coding scheme and methodology. Next, we establish reliability between live coders and between the transcript coders. We conclude by employing our coding scheme to examine how occupational status (physician vs. nurse) operates in medical teams, and find that our scheme possesses both criterion and face validity. Future steps include increasing our sample size to have more statistical power in detecting status differences and dropping some items from the coding scheme to increase reliability.

Adapting to the task environment: Explorations in expected value  

E-Print Network (OSTI)

Small variations in how a task is designed can lead humans to trade off one set of strategies for another. In this paper we discuss our failure to model such tradeoffs in the Blocks World task using ACT-Rs default mechanism for selecting the best production among competing productions. ACT-Rs selection mechanism, its expected value equation, has had many successes (see, for example [Anderson, J. R., & Lebiere, C. (Eds.). (1998). Atomic components of thought. Hillsdale, NJ: Lawrence Erlbaum Associates.]) and a recognized strength of this approach is that, across a wide variety of tasks, it tends to produce models that adapt to their task environment about as fast as humans adapt. (This congruence with human behavior is in marked contrast to other popular ways of computing the utility of alternative choices; for example, Reinforcement Learning or most Connectionist learning methods.) We believe that the failure to model the Blocks World task stems from the requirement in ACT-R that all actions must be counted as a binary success or failure. In Blocks World, as well as in many other circumstances, actions can be met with mixed success or partial failure. Working within ACT-Rs expected value equation we replace the binary success/failure judgment with three variations on a scalar one. We then compare the performance of each alternative with ACT-Rs default scheme and with the human data. We conclude by discussing the limits and generality of our attempts to replace ACT-Rs binary scheme with a scalar credit assignment mechanism.

From it we construct the Fock representation of an orthosymplectic Lie superalgebra osp associated to V. Particular attention is paid to defining Howe's oscillator semigroup and the representation that partially exponentiates the Lie algebra representation of sp in osp. In the process, by pushing the semigroup representation to its boundary and arguing by continuity, we provide a construction of the Shale-Weil-Segal representation of the metaplectic group. To deal with a product of n ratios of characteristic polynomials, we let V = C^n \\otimes C^N where C^N is equipped with its standard K-representation, and focus on the subspace of K-equivariant forms. By Howe duality, this is a highest-weight irreducible representation of the centralizer g of Lie(K) in osp. We identify the K-Haar expectation of n ratios with the character of this g-representation, which we show to be uniquely determined by analyticity, Weyl group invariance, certain weight constraints and a system of differential equations coming from the Laplace-Casimir invariants of g. We find an explicit solution to the problem posed by all these conditions. In this way we prove that the said Haar expectations are expressed by a Weyl-type character formula for all integers N \\ge 1. This completes earlier work by Conrey, Farmer, and Zirnbauer for the case of U(N).

Testing the accuracy of the Hydro-PM approximation in numerical simulations of the Lyman-alpha forest  

E-Print Network (OSTI)

We implement the hydro-PM (HPM) technique (Gnedin & Hui 1998) in the hydrodynamical simulation code GADGET-II and quantify the differences between this approximate method and full hydrodynamical simulations of the Lyman-alpha forest in a concordance LCDM model. At redshifts z=3 and z=4, the differences between the gas and dark matter (DM) distributions, as measured by the one-point distribution of density fluctuations, the density power spectrum and the flux power spectrum, systematically decrease with increasing resolution of the HPM simulqation. However, reducing these differences to less than a few percent requires a significantly larger number of grid-cells than particles, with a correspondingly larger demand for memory. Significant differences in the flux decrement distribution remain even for very high resolution hydro-PM simulations, particularly at low redshift. At z=2, the differences between the flux power spectra obtained from HPM simulations and full hydrodynamical simulations are generally la...

CO{sub 2} Geologic Storage: Coupled Hydro-Chemo-Thermo-Mechanical Phenomena - From Pore-scale Processes to Macroscale Implications -  

SciTech Connect

Global energy consumption will increase in the next decades and it is expected to largely rely on fossil fuels. The use of fossil fuels is intimately related to CO{sub 2} emissions and the potential for global warming. Geological CO{sub 2} storage aims to mitigate the global warming problem by sequestering CO{sub 2} underground. Coupled hydro-chemo-mechanical phenomena determine the successful operation and long term stability of CO{sub 2} geological storage. This research explores coupled phenomena, identifies different zones in the storage reservoir, and investigates their implications in CO{sub 2} geological storage. In particular, the research: Explores spatial patterns in mineral dissolution and precipitation (comprehensive mass balance formulation); experimentally determines the interfacial properties of water, mineral, and CO{sub 2} systems (including CO{sub 2}-water-surfactant mixtures to reduce the CO{sub 2}- water interfacial tension in view of enhanced sweep efficiency); analyzes the interaction between clay particles and CO{sub 2}, and the response of sediment layers to the presence of CO{sub 2} using specially designed experimental setups and complementary analyses; couples advective and diffusive mass transport of species, together with mineral dissolution to explore pore changes during advection of CO{sub 2}-dissolved water along a rock fracture; upscales results to a porous medium using pore network simulations; measures CO{sub 2} breakthrough in highly compacted fine-grained sediments, shale and cement specimens; explores sealing strategies; and experimentally measures CO{sub 2}-CH{sub 4} replacement in hydrate-bearing sediments during. Analytical, experimental and numerical results obtained in this study can be used to identify optimal CO{sub 2} injection and reservoir-healing strategies to maximize the efficiency of CO{sub 2} injection and to attain long-term storage.

3D-radiation hydro simulations of disk-planet interactions: I. Numerical algorithm and test cases  

E-Print Network (OSTI)

We study the evolution of an embedded protoplanet in a circumstellar disk using the 3D-Radiation Hydro code TRAMP, and treat the thermodynamics of the gas properly in three dimensions. The primary interest of this work lies in the demonstration and testing of the numerical method. We show how far numerical parameters can influence the simulations of gap opening. We study a standard reference model under various numerical approximations. Then we compare the commonly used locally isothermal approximation to the radiation hydro simulation using an equation for the internal energy. Models with different treatments of the mass accretion process are compared. Often mass accumulates in the Roche lobe of the planet creating a hydrostatic atmosphere around the planet. The gravitational torques induced by the spiral pattern of the disk onto the planet are not strongly affected in the average magnitude, but the short time scale fluctuations are stronger in the radiation hydro models. An interesting result of this work lies in the analysis of the temperature structure around the planet. The most striking effect of treating the thermodynamics properly is the formation of a hot pressure--supported bubble around the planet with a pressure scale height of H/R ~ 0.5 rather than a thin Keplerian circumplanetary accretion disk. We also observe an outflow of gas above and below the planet during the gap opening phase.

Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics  

Science Conference Proceedings (OSTI)

The Large Hadron Collider (LHC) at CERN promises a major step forward in the understanding of the fundamental nature of matter. The ATLAS experiment is a general-purpose detector for the LHC, whose design was guided by the need to accommodate the wide spectrum of possible physics signatures. The major remit of the ATLAS experiment is the exploration of the TeV mass scale where groundbreaking discoveries are expected. In the focus are the investigation of the electroweak symmetry breaking and linked to this the search for the Higgs boson as well as the search for Physics beyond the Standard Model. In this report a detailed examination of the expected performance of the ATLAS detector is provided, with a major aim being to investigate the experimental sensitivity to a wide range of measurements and potential observations of new physical processes. An earlier summary of the expected capabilities of ATLAS was compiled in 1999 [1]. A survey of physics capabilities of the CMS detector was published in [2]. The design of the ATLAS detector has now been finalised, and its construction and installation have been completed [3]. An extensive test-beam programme was undertaken. Furthermore, the simulation and reconstruction software code and frameworks have been completely rewritten. Revisions incorporated reflect improved detector modelling as well as major technical changes to the software technology. Greatly improved understanding of calibration and alignment techniques, and their practical impact on performance, is now in place. The studies reported here are based on full simulations of the ATLAS detector response. A variety of event generators were employed. The simulation and reconstruction of these large event samples thus provided an important operational test of the new ATLAS software system. In addition, the processing was distributed world-wide over the ATLAS Grid facilities and hence provided an important test of the ATLAS computing system - this is the origin of the expression 'CSC studies' ('computing system commissioning'), which is occasionally referred to in these volumes. The work reported does generally assume that the detector is fully operational, and in this sense represents an idealised detector: establishing the best performance of the ATLAS detector with LHC proton-proton collisions is a challenging task for the future. The results summarised here therefore represent the best estimate of ATLAS capabilities before real operational experience of the full detector with beam. Unless otherwise stated, simulations also do not include the effect of additional interactions in the same or other bunch-crossings, and the effect of neutron background is neglected. Thus simulations correspond to the low-luminosity performance of the ATLAS detector. This report is broadly divided into two parts: firstly the performance for identification of physics objects is examined in detail, followed by a detailed assessment of the performance of the trigger system. This part is subdivided into chapters surveying the capabilities for charged particle tracking, each of electron/photon, muon and tau identification, jet and missing transverse energy reconstruction, b-tagging algorithms and performance, and finally the trigger system performance. In each chapter of the report, there is a further subdivision into shorter notes describing different aspects studied. The second major subdivision of the report addresses physics measurement capabilities, and new physics search sensitivities. Individual chapters in this part discuss ATLAS physics capabilities in Standard Model QCD and electroweak processes, in the top quark sector, in b-physics, in searches for Higgs bosons, supersymmetry searches, and finally searches for other new particles predicted in more exotic models.

Expected behavior of plutonium in the IFR fuel cycle  

Science Conference Proceedings (OSTI)

The Integral Fast Reactor (IFR) is a metal-fueled, sodium-cooled reactor that will consist initially of a U-Zr alloy core in which the enriched uranium will be replaced gradually by plutonium bred in a uranium blanket. The plutonium is concentrated to the required level by extraction from the molten blanket material with a CaCl/sub 2/-BaCl/sub 2/ salt containing MgCl/sub 2/ as an oxidant (halide slagging). The CaCl/sub 2/-BaCl/sub 2/ salt containing dissolved PuCl/sub 3/ and UCl/sub 3/ is added to the core process where fission products are removed by electrorefining, using a liquid cadmium anode, a metal cathode, and a LiCl-NaCl-CaCl/sub 2/-BaCl/sub 2/ molten salt electrolyte. The product is recovered as a metallic deposit on the cathode. The halide slagging step is operated at about 1250/sup 0/ and the electrorefining step at about 450/sup 0/C. These processes are expected to give low fission-product decontamination factors of the order of 100.

Why the Earth has not warmed as much as expected?  

Science Conference Proceedings (OSTI)

The observed increase in global mean surface temperature (GMST) over the industrial era is less than 40% of that expected from observed increases in long-lived greenhouse gases together with the best-estimate equilibrium climate sensitivity given by the 2007 Assessment Report of the Intergovernmental Panel on Climate Change. Possible reasons for this warming discrepancy are systematically examined here. The warming discrepancy is found to be due mainly to some combination of two factors: the IPCC best estimate of climate sensitivity being too high and/or the greenhouse gas forcing being partially offset by forcing by increased concentrations of atmospheric aerosols; the increase in global heat content due to thermal disequilibrium accounts for less than 25% of the discrepancy, and cooling by natural temperature variation can account for only about 15%. Current uncertainty in climate sensitivity is shown to preclude determining the amount of future fossil fuel CO2 emissions that would be compatible with any chosen maximum allowable increase in GMST; even the sign of such allowable future emissions is unconstrained. Resolving this situation, by empirical determination of the earth's climate sensitivity from the historical record over the industrial period or through use of climate models whose accuracy is evaluted by their performance over this period, is shown to require substantial reduction in the uncertainty of aerosol forcing over this period.

Monte Carlo: in the beginning and some great expectations  

SciTech Connect

The central theme will be on the historical setting and origins of the Monte Carlo Method. The scene was post-war Los Alamos Scientific Laboratory. There was an inevitability about the Monte Carlo Event: the ENIAC had recently enjoyed its meteoric rise (on a classified Los Alamos problem); Stan Ulam had returned to Los Alamos; John von Neumann was a frequent visitor. Techniques, algorithms, and applications developed rapidly at Los Alamos. Soon, the fascination of the Method reached wider horizons. The first paper was submitted for publication in the spring of 1949. In the summer of 1949, the first open conference was held at the University of California at Los Angeles. Of some interst perhaps is an account of Fermi's earlier, independent application in neutron moderation studies while at the University of Rome. The quantum leap expected with the advent of massively parallel processors will provide stimuli for very ambitious applications of the Monte Carlo Method in disciplines ranging from field theories to cosmology, including more realistic models in the neurosciences. A structure of multi-instruction sets for parallel processing is ideally suited for the Monte Carlo approach. One may even hope for a modest hardening of the soft sciences.

Quantifying mortal injury of juvenile Chinook salmon exposed to simulated hydro-turbine passage  

Science Conference Proceedings (OSTI)

A proportion of juvenile Chinook salmon and other salmonids travel through one or more turbines during seaward migration in the Columbia and Snake River every year. Despite this understanding, limited information exists on how these fish respond to hydraulic pressures found during turbine passage events. In this study we exposed juvenile Chinook salmon to varied acclimation pressures and subsequent exposure pressures (nadir) to mimic the hydraulic pressures of large Kaplan turbines (ratio of pressure change). Additionally, we varied abiotic (total dissolved gas, rate of pressure change) and biotic (condition factor, fish length, fish weight) factors that may contribute to the incidence of mortal injury associated with fish passing through hydro-turbines. We determined that the main factor associated with mortal injury of juvenile Chinook salmon during simulated turbine passage was the ratio between acclimation and nadir pressures. Condition factor, total dissolved gas, and the rate of pressure change were found to only slightly increase the predictive power of equations relating probability of mortal injury to conditions of exposure or characteristics of test fish during simulated turbine passage. This research will assist engineers and fisheries managers in operating and improving hydroelectric facility efficiency while minimizing mortality and injury of turbine-passed juvenile Chinook salmon. The results are discussed in the context of turbine development and the necessity of understanding how different species of fish will respond to the hydraulic pressures of turbine passage.

Hydro-gravitational fragmentation, diffusion and condensation of the primordial plasma, dark-matter and gas  

E-Print Network (OSTI)

The first structures were proto-voids formed in the primordial plasma. Viscous and weak turbulence forces balanced gravitational forces when the scale of causal connection at time 30,000 years matched the viscous and turbulent Schwarz scales of hydro-gravitational theory (Gibson 1996). The photon viscosity allows only weak turbulence from the Reynolds number Re = 200, with fragmentation to give proto-supercluster voids, buoyancy forces, fossil vorticity turbulence, and strong sonic damping. The expanding, cooling, plasma continued fragmentation to proto-galaxy-mass with the density and rate-of-strain preserved as fossils of the weak turbulence and first structure. Turbulence fossilization by self-gravitational buoyancy explains the cosmic microwave background temperature fluctuations, not sonic oscillations in cold-dark-matter fragments. After plasma to gas transition at 300,000 years, gas fragmentation occurred within the proto-galaxies to form proto-globular-star-cluster (PGCs) clouds of small-planetary-mass primordial-fog-particles (PFPs). Dark PGC clumps of frozen PFPs persist as the inner-galaxy-halo dark matter, supporting Schild's 1996 quasar-microlensing interpretation. Non-baryonic dark matter diffused into the plasma proto-cluster-voids and later fragmented as outer-galaxy-halos at diffusive Schwarz scales, indicating light, weakly-collisional fluid particles (possibly neutrinos). Observations support the theory (Gibson and Schild 2003).

Interpretation of the Helix Planetary Nebula using Hydro-Gravitational Theory  

E-Print Network (OSTI)

Wide angle Hubble Space Telescope (HST/ACS) images of the Helix Planetary Nebula (NGC 7293) are interpreted using the hydro-gravitational theory (HGT) of Gibson 1996-2000 that predicts the baryonic dark matter and interstellar medium (ISM) consists of Mars-mass primordial-fog-particle (PFP) frozen H-He planets. The new ACS images confirm and extend the O'Dell and Handron 1996 WFPC2 images showing thousands of cometary globules, which we suggest are cocoons of PFP and Jupiter frozen-gas-planets evaporated by powerful beamed radiation from the hot central white dwarf and its companion. The atmosphere mass of the largest cometary globules is ~ 3x10^{25} kg with spacing ~ 10^{14} m, supporting the prediction of HGT that the mass density of the ISM in Galaxy star forming regions should match the large baryonic primordial value at the time of first structure formation (10^{12} s or 30,000 years), with \\rho ~ (3-1)x 10^{-17} kg m^{-3}.

Interpretation of the Stephan Quintet Galaxy Cluster using Hydro-Gravitational Theory  

E-Print Network (OSTI)

Stephan's Quintet (SQ) is a compact group of galaxies that has been well studied since its discovery in 1877 but is mysterious using cold dark matter hierarchical clustering cosmology (CDMHCC). Anomalous red shifts z = (0.0027,0.019, 0.022, 0.022, 0.022) among galaxies in SQ either; reduce it to a Trio with two highly improbable intruders from CDMHCC, or support the Arp (1973) hypothesis that its red shifts may be intrinsic. An alternative is provided by the Gibson 1996-2000 hydro-gravitational-theory (HGT) where superclusters, clusters and galaxies all originate by universe expansion and gravitational fragmentation in the super-viscous plasma epoch (after which the gas condenses as 10^{24} kg fog-particles in metastable 10^{36} kg dark-matter-clumps). By this fluid mechanical cosmology, the SQ galaxies gently separated recently and remain precisely along a line of sight because of perspective and the small transverse velocities permitted by their sticky, viscous-gravitational, beginnings. Star and gas bridges and young-globular-star-cluster (YGC) trails observed by the HST are triggered as SQ galaxies separate through each other's frozen baryonic-dark-matter halos of dark proto-globular-cluster (PGC) clumps of planetary-mass primordial-fog-particles (PFPs). Discordant red shifts (from CDMHCC) between angularly clustered quasars and bright galaxies are similarly explained by HGT.

Interpretation of the Tadpole VV29 Merging Galaxy System using Hydro-Gravitational Theory  

E-Print Network (OSTI)

Hubble Space Telescope (HST/ACS) images of the galaxy merger Tadpole are interpreted using the hydro-gravitational theory of Gibson 1996-2000 (HGT) that predicts galaxy masses within about 100 kpc are dominated by dark halos of planetary mass primordial-fog-particles (PFPs) in dark proto-globular-star-clusters (PGCs). According to our interpretation, stars and young-globular-clusters (YGCs) appear out of the dark as merging galaxy components VV29cdef move through the baryonic-dark-matter halo of the larger galaxy VV29a creating luminous star-wakes. Frozen PFP planets are evaporated by radiation and tidal forces of the intruders. Friction from the gas accelerates an accretional cascade of PFPs to form larger planets, stars and YGCs of the filamentary galaxy VV29b. Star-wakes show that galaxy VV29c, identified as a blue dwarf by radio telescope observations of gas density and velocity (Briggs et al. 2001), with companions VV29def entered the dark halo of the larger VV29a galaxy at a radius 130 kpc and then spiraled in on different tracks toward frictional capture by the VV29a core. A previously dark dwarf galaxy is identified from a Keck spectrographic study showing a VV29c star-wake dense cluster of YGCs aligned to 1 degree in a close straight row (Tran et al. 2003).

Water Management Lessons for California from Statewide Hydro-economic Modeling Using the CALVIN Model  

E-Print Network (OSTI)

Californias complex water management system often defies comprehensive analysis. We summarize the results of a decade of quantification and analysis of this system from a hydro-economic perspective using the CALVIN Model. The general approach taken dates back to Roman times, when Frontinus (97 AD) began his oversight of Romes water system with a systematic inventory and quantification of its water system. This approach has been formalized and expanded in the modern era as economists, planners, and engineers have sought to grapple with complex water management systems and problems. In California water supply and demands are inconvenient in space and time. Most water availability is in northern California from winter precipitation and spring snow-melt; whereas water demands are more in the south during the dry summer. Consequently, major floods and seasonal and multiyear droughts characterize water resources in California. The Sacramento-San Joaquin Delta is the major north-south hub for this water network. Population growth, climate change, a vulnerable Delta, and decentralized water governance pose opportunities and challenges to water management in California. Portfolios of water management activities, including diverse general policy tools, demand management, and operations and supply expansion options, are available to manage competing demands in complex situations. Exploring promising portfolios of actions is the main intent of the CALVIN model. The CALVIN model

Hydro-ball in-core instrumentation system and method of operation  

DOE Patents (OSTI)

A hydro-ball in-core instrumentation system employs detector strings each comprising a wire having radiation sensitive balls affixed diametrically at spaced positions therealong and opposite tip ends of which are transportable by fluid drag through interior passageways. In the passageways primary coolant is caused to flow selectively in first and second opposite directions for transporting the detector strings from stored positions in an exterior chamber to inserted positions within the instrumentation thimbles of the fuel rod assemblies of a pressure vessel, and for return. The coolant pressure within the detector passageways is the same as that within the vessel; face contact, disconnectable joints between sections of the interior passageways within the vessel facilitate assembly and disassembly of the vessel for refueling and routine maintenance operations. The detector strings may pass through a very short bend radius thereby minimizing space requirements for the connections of the instrumentation system to the vessel and concomitantly the vessel containment structure. Improved radiation mapping and a significant reduction in potential exposure of personnel to radiation are provided. Both top head and bottom head penetration embodiments are disclosed.

Optimizing hourly hydro operations at the Salt Lake City Area integrated projects  

DOE Green Energy (OSTI)

The Salt Lake City Area (SLCA) office of the Western Area Power Administration (Western) is responsible for marketing the capacity and energy generated by the Colorado Storage, Collbran, and Rio Grande hydropower projects. These federal resources are collectively called the Salt Lake City Area Integrated Projects (SLCA/IP). In recent years, stringent operational limitations have been placed on several of these hydropower plants including the Glen Canyon Dam, which accounts for approximately 80% of the SLCA/IP resources. Operational limitations on SLCA/IP hydropower plants continue to evolve as a result of decisions currently being made in the Glen Canyon Dam Environmental Impact Statement (EIS) and the Power Marketing EIS. To analyze a broad range of issues associated with many possible future operational restrictions, Argonne National Laboratory (ANL), with technical assistance from Western has developed the Hydro LP (Linear Program) Model. This model simulates hourly operations at SLCA/IP hydropower plants for weekly periods with the objective of maximizing Western`s net revenues. The model considers hydropower operations for the purpose of serving SLCA firm loads, loads for special projects, Inland Power Pool (IPP) spinning reserve requirements, and Western`s purchasing programs. The model estimates hourly SLCA/IP generation and spot market activities. For this paper, hourly SLCA/IP hydropower plant generation is simulated under three operational scenarios and three hydropower conditions. For each scenario an estimate of Western`s net revenue is computed.

E-Print Network (OSTI)

Stephan's Quintet (SQ) is a compact group of galaxies that has been well studied since its discovery in 1877 but is mysterious using cold dark matter hierarchical clustering cosmology (CDMHCC). Anomalous red shifts $z = (0.0027,0.019, 0.022, 0.022, 0.022)$ among galaxies in SQ either reduce it to a Trio with two highly improbable intruders from CDMHCC or support the Arp (1973) hypothesis that its red shifts are intrinsic. An alternative is provided by the Gibson 1996-2006 hydro-gravitational-dynamics (HGD) theory where superclusters, clusters and galaxies all originate by gravitational fragmentation in the super-viscous plasma epoch and at planetary and star cluster mass scales in the primordial gas of the expanding universe. By this fluid-mechanical cosmology, the SQ galaxies gently separate and remain precisely along a line of sight because of perspective and the small transverse velocities permitted by their sticky viscous-gravitational beginnings.

Interpretation of the Helix Planetary Nebula using Hydro-Gravitational-Dynamics: Planets and Dark Energy  

E-Print Network (OSTI)

Hubble Space Telescope images of the Helix Planetary Nebula are interpreted using the hydro-gravitational-dynamics theory (HGD) of Gibson 1996-2006. HGD claims that baryonic-dark-matter (BDM) dominates the halo masses of galaxies (Schild 1996) as Jovian (Primordial-fog-particle [PFP]) Planets (JPPs) in proto-globular-star-cluster (PGC) clumps for all galaxy halo diameters bounded by stars. From HGD, supernova Ia (SNe Ia) events always occur in planetary nebulae (PNe) within PGCs. The dying central star of a PNe slowly accretes JPP mass to grow the white-dwarf to instability. Plasma jets, winds and radiation driven by contraction and spin-up of the carbon star evaporate JPPs revealing its Oort accretional cavity. SNe Ia events may thus be obscured or not obscured by radiation-inflated JPP atmospheres producing systematic SNe Ia distance errors, so the otherwise mysterious ``dark energy'' concept is unnecessary. HST/ACS and WFPC2 Helix images show >7,000 cometary globules and SST/IRAC images show >20,000-40,000, here interpreted as gas-dust cocoons of JPPs evaporated by the spin powered radiation of the PNe central white-dwarf. Observed JPP masses fossilizes the primordial density existing when the plasma universe fragmented into proto-superclusters, proto-clusters, and proto-galaxies. Pulsar scintillation spectra support the postulated multi-planet atmospheres.

Energy Efficiency Services Sector: Workforce Size and Expectations for Growth  

SciTech Connect

The energy efficiency services sector (EESS) is poised to become an increasingly important part of the U.S. economy. Climate change and energy supply concerns, volatile and increasing energy prices, and a desire for greater energy independence have led many state and national leaders to support an increasingly prominent role for energy efficiency in U.S. energy policy. The national economic recession has also helped to boost the visibility of energy efficiency, as part of a strategy to support economic recovery. We expect investment in energy efficiency to increase dramatically both in the near-term and through 2020 and beyond. This increase will come both from public support, such as the American Recovery and Reinvestment Act (ARRA) and significant increases in utility ratepayer funds directed toward efficiency, and also from increased private spending due to codes and standards, increasing energy prices, and voluntary standards for industry. Given the growing attention on energy efficiency, there is a concern among policy makers, program administrators, and others that there is an insufficiently trained workforce in place to meet the energy efficiency goals being put in place by local, state, and federal policy. To understand the likelihood of a potential workforce gap and appropriate response strategies, one needs to understand the size, composition, and potential for growth of the EESS. We use a bottom-up approach based upon almost 300 interviews with program administrators, education and training providers, and a variety of EESS employers and trade associations; communications with over 50 sector experts; as well as an extensive literature review. We attempt to provide insight into key aspects of the EESS by describing the current job composition, the current workforce size, our projections for sector growth through 2020, and key issues that may limit this growth.

Research and development of the Osmo-Hydro Power heat engine. Final report  

SciTech Connect

The Osmo-Hydro Power (OHP) or Pressure-Retarded Osmosis (PRO) heat engine is a possible means for producing economical electric power from low-temperature heat sources. The engine utilizes semipermeable membranes to cause the permeation of a solvent from a dilute low-pressure solution to a concentrated high-pressure solution. The potential energy thus acquired is converted to useful energy by means of a turbogenerator. The process can be considered as one in which the free energy of mixing is converted to useful power. By appropriate application of a heat source and a heat sink, the original dilute and concentrated solutions are recovered, thus completing the heat engine cycle. The results of this initial project to study osmotic power generation from waste heat indicate what research paths must be followed to continue the development of distillation and conjugation as unmixing methods. In addition, precipitation and stratification have been shown to be desirable because of the possibility of readily matching a binary system with either a membrane presently available or one readily modified from an existing membrane. The OHP heat engine in its ultimate development would have the following general characteristics: it would be able to utilize low-grade heat sources, such as unconcentrated solar energy or waste heat below 100/sup 0/C., heat sources as low as 50/sup 0/C can be used; the engine should be able to produce electricity for 0.12 $/kWh, or less, but the thermal efficiency will be less than 25% of Carnot efficiency at the same temperature limits; and the engine would be modular; i.e., it could be scaled up or down largely by adding or subtracting discrete permeator and heat exchanger units.

Stochastic Analysis of Waterhammer and Applications in Reliability-Based Structural Design for Hydro Turbine Penstocks  

Science Conference Proceedings (OSTI)

Abstract: The randomness of transient events, and the variability in factors which influence the magnitudes of resultant pressure fluctuations, ensures that waterhammer and surges in a pressurized pipe system are inherently stochastic. To bolster and improve reliability-based structural design, a stochastic model of transient pressures is developed for water conveyance systems in hydropower plants. The statistical characteristics and probability distributions of key factors in boundary conditions, initial states and hydraulic system parameters are analyzed based on a large record of observed data from hydro plants in China; and then the statistical characteristics and probability distributions of annual maximum waterhammer pressures are simulated using Monte Carlo method and verified by the analytical probabilistic model for a simplified pipe system. In addition, the characteristics (annual occurrence, sustaining period and probability distribution) of hydraulic loads for both steady and transient states are discussed. Illustrating with an example of penstock structural design, it is shown that the total waterhammer pressure should be split into two individual random variable loads: the steady/static pressure and the waterhammer pressure rise during transients; and that different partial load factors should be applied to each individual load to reflect its unique physical and stochastic features. Particularly, the normative load (usually the unfavorable value at 95-percentage point) for steady/static hydraulic pressure should be taken from the probability distribution of its maximum values during the pipe's design life, while for waterhammer pressure rise, as the second variable load, the probability distribution of its annual maximum values is used to determine its normative load.

A two-stage planning model for power scheduling in a hydro-thermal system under uncertainty  

E-Print Network (OSTI)

Abstract. A two-stage stochastic programming model for the short- or mid-term cost-optimal electric power production planning is developed. We consider the power generation in a hydro-thermal generation system under uncertainty in demand (or load) and prices for fuel and delivery contracts. The model involves a large number of mixed-integer (stochastic) decision variables and constraints linking time periods and operating power units. A stochastic Lagrangian relaxation scheme is designed by assigning (stochastic) multipliers to all constraints that couple power units. It is assumed that the stochastic load and price processes are given (or approximated) by a finite number of realizations (scenarios). Solving the dual by a bundle subgradient method leads to a successive decomposition into stochastic single unit subproblems. The stochastic thermal and hydro subproblems are solved by a stochastic dynamic programming technique and by a specific descent algorithm, respectively. A Lagrangian heuristics that provides approximate solutions for the primal problem is developed. Numerical results are presented for realistic data from a German power utility and for numbers of scenarios ranging from 5 to 100 and a time horizon of 168 hours. The sizes of the corresponding optimization problems go up to 400.000 binary and 650.000 continuous variables, and more than 1.300.000 constraints.

Training and Research on Probabilistic Hydro-Thermo-Mechanical Modeling of Carbon Dioxide Geological Sequestration in Fractured Porous Rocks  

SciTech Connect

Colorado School of Mines conducted research and training in the development and validation of an advanced CO{sub 2} GS (Geological Sequestration) probabilistic simulation and risk assessment model. CO{sub 2} GS simulation and risk assessment is used to develop advanced numerical simulation models of the subsurface to forecast CO2 behavior and transport; optimize site operational practices; ensure site safety; and refine site monitoring, verification, and accounting efforts. As simulation models are refined with new data, the uncertainty surrounding the identified risks decrease, thereby providing more accurate risk assessment. The models considered the full coupling of multiple physical processes (geomechanical and fluid flow) and describe the effects of stochastic hydro-mechanical (H-M) parameters on the modeling of CO{sub 2} flow and transport in fractured porous rocks. Graduate students were involved in the development and validation of the model that can be used to predict the fate, movement, and storage of CO{sub 2} in subsurface formations, and to evaluate the risk of potential leakage to the atmosphere and underground aquifers. The main major contributions from the project include the development of: 1) an improved procedure to rigorously couple the simulations of hydro-thermomechanical (H-M) processes involved in CO{sub 2} GS; 2) models for the hydro-mechanical behavior of fractured porous rocks with random fracture patterns; and 3) probabilistic methods to account for the effects of stochastic fluid flow and geomechanical properties on flow, transport, storage and leakage associated with CO{sub 2} GS. The research project provided the means to educate and train graduate students in the science and technology of CO{sub 2} GS, with a focus on geologic storage. Specifically, the training included the investigation of an advanced CO{sub 2} GS simulation and risk assessment model that can be used to predict the fate, movement, and storage of CO{sub 2} in underground formations, and the evaluation of the risk of potential CO{sub 2} leakage to the atmosphere and underground aquifers.

Testing the accuracy of the Hydro-PM approximation in numerical simulations of the Lyman-alpha forest  

E-Print Network (OSTI)

We implement the hydro-PM (HPM) technique (Gnedin & Hui 1998) in the hydrodynamical simulation code GADGET-II and quantify the differences between this approximate method and full hydrodynamical simulations of the Lyman-alpha forest in a concordance LCDM model. At redshifts z=3 and z=4, the differences between the gas and dark matter (DM) distributions, as measured by the one-point distribution of density fluctuations, the density power spectrum and the flux power spectrum, systematically decrease with increasing resolution of the HPM simulqation. However, reducing these differences to less than a few percent requires a significantly larger number of grid-cells than particles, with a correspondingly larger demand for memory. Significant differences in the flux decrement distribution remain even for very high resolution hydro-PM simulations, particularly at low redshift. At z=2, the differences between the flux power spectra obtained from HPM simulations and full hydrodynamical simulations are generally large and of the order of 20-30 %, and do not decrease with increasing resolution of the HPM simulation. This is due to the presence of large amounts of shock-heated gas, a situation which is not adequately modelled by the HPM approximation. We confirm the results of Gnedin & Hui (1998) that the statistical properties of the flux distribution are discrepant by > 5-20 % when compared to full hydrodynamical simulations. The discrepancies in the flux power spectrum are strongly scale- and redshift-dependent and extend to large scales. Considerable caution is needed in attempts to use calibrated HPM simulations for quantitative predictions of the flux power spectrum and other statistical properties of the Lyman-alpha forest.

Study of community leaders in a nuclear host community: local issues, expectations and support and opposition  

SciTech Connect

A study of community leaders was undertaken in Hartsville, Tennessee, site of the TVA Hartsville Nuclear Power Plant currently under construction. Leaders were found to be extremely supportive of the plant and of TVA's efforts to mitigate impacts expected to result from construction. Like their citizen counterparts, leaders expect economic benefits and some growth-related disruption to occur as a result of the plant, while environmental impacts are seen as extremely unlikely to occur. Plant-related issues, such as housing availability and traffic congestion, dominate leaders' thinking about current issues.

Cumulative Effects of Micro-Hydro Development on the Fisheries of the Swan River Drainage, Montana, First Annual Progress Report (Covering Field Season July-November 1982).  

DOE Green Energy (OSTI)

This fisheries study is to determine the potential cumulative biological and economic effects of 20 small or micro-hydro-electric facilities (less than 5 megawatts) proposed to be constructed on tributaries to the Swan River, a 1738 square kilometer (671 square mile) drainage located in northwestern Montana. The study addresses portions of measure 1204 (b) (2) of the Norwthwest Power Planning Council's Columbia River Basin Fish and Wildlife Program. Aerial pre-surveys conducted during 1982 identified 102 stream reaches that may support fish populations in the Swan drainage between Swan and Lindbergh lakes. These reaches were located in 49 tributary streams and constituted 416 kilometers (258 miles) of potential fish habitat. Construction of all proposed small hydro projects would divert water from 54 kilometers (34 miles) or about 13 percent of the tributary system. Only two of the 20 proposed hydro sites did not support trout populations and most were populated by migratory bull trout and westslope cutthroat trout. Potential cumulative habitat losses that could result from dewatering of all proposed project areas were predicted using a stream reach classification scheme involving stream gradient, drainage ara, and fish population data. Preliminary results of this worst case analysis indicate that 23, 19 and 6 percent of the high quality rearing habitat for cutthroat, bull, and brook trout respectively would be lost.

Evidence for Hydro-Gravitational Structure Formation Theory versus Cold-Dark-Matter, Hierarchical-Clustering, and Jeans 1902  

E-Print Network (OSTI)

Observations are compared to conflicting predictions about self-gravitational structure formation by the hydro-gravitational theory (HGT) of Gibson 1996-2003 versus cold-dark-matter hierarchical-clustering-cosmology (CDMHCC) and the Jeans 1902 criterion. According to HGT, gravitational structures form immediately after mass-energy equality by plasma fragmentation at 30,000 years when viscous and weak turbulence forces first balance gravitational forces within the horizon L_H = ct < L_J = c/[3\\rho G]^1/2, contrary to the Jeans 1902 criterion. Buoyancy forces fossilize the 10^-12 s^-1 rate-of-strain and the 10^-17 kg m^-3 baryonic density. The non-baryonic dark matter (NBDM) diffuses into the voids rather than forming cold-dark-matter (CDM) halos required by CDMHCC. From HGT, supercluster-mass to galaxy-mass fragments exist at the plasma to gas transition, and these fragment further to form proto-globular-star clusters (PGCs) and planetary-mass primordial-fog-particles (PFPs): the baryonic dark matter of the interstellar-medium and inner-galaxy-dark-matter-halos, from which all planets and stars are formed by accretion (Gibson 1996, Schild 1996). From HGT and a rich cluster mass profile (Tyson and Fischer 1995), D_NBDM = 6 x10^28 m^2 s^-1, m_NBDM <= 10^-33 kg, and the NBDM forms outer-galaxy halos after 300,000 years.

Halo expansion in cosmological hydro simulations: towards a baryonic solution of the cusp/core problem in massive spirals  

E-Print Network (OSTI)

A clear prediction of the Cold Dark Matter model is the existence of cuspy dark matter halo density profiles on all mass scales. This is not in agreement with the observed rotation curves of spiral galaxies, challenging on small scales the otherwise successful CDM paradigm. In this work we employ high resolution cosmological hydro-dynamical simulations to study the effects of dissipative processes on the inner distribution of dark matter in Milky-Way like objects (M~1e12 Msun). Our simulations include supernova feedback, and the effects of the radiation pressure of massive stars before they explode as supernovae. The increased stellar feedback results in the expansion of the dark matter halo instead of contraction with respect to N-body simulations. Baryons are able to erase the dark matter cuspy distribution creating a flat, cored, dark matter density profile in the central several kpc of a massive Milky-Way like halo. The profile is well fit by a Burkert profile, with fitting parameters consistent with the ...

Active hurricane season expected to shut-in higher amount of Active hurricane season expected to shut-in higher amount of oil and natural gas production An above-normal 2013 hurricane season is expected to cause a median production loss of about 19 million barrels of U.S. crude oil and 46 billion cubic feet of natural gas production in the Gulf of Mexico, according to the new forecast from the U.S. Energy Information Administration. That's about one-third more than the amount of oil and gas production knocked offline during last year's hurricane season. Government weather forecasts predict 13 to 20 named storms will form between June and the end of November, with 7 to 11 of those turning into hurricanes. Production outages in previous hurricane seasons were as high as 107 million barrels of crude oil

On Estimating the Conditional Expected Shortfall Franco Peracchi and Andrei V.  

E-Print Network (OSTI)

Unlike the value at risk, the expected shortfall is a coherent measure of risk. In this paper, we discuss estimation of the expected shortfall of a random variable Yt with special reference to the case when auxiliary information is available in the form of a set of predictors Xt. We consider three classes of estimators of the conditional expected shortfall of Yt given Xt: a class of fully non-parametric estimators and two classes of analog estimators based, respectively, on the empirical conditional quantile function and the empirical conditional distribution function. We study their sampling properties by means of a set of Monte Carlo experiments and analyze their performance in an empirical application to financial data.

Wavefunctions, Green's functions and expectation values in terms of spectral determinants  

E-Print Network (OSTI)

We derive semiclassical approximations for wavefunctions, Green's functions and expectation values for classically chaotic quantum systems. Our method consists of applying singular and regular perturbations to quantum Hamiltonians. The wavefunctions, Green's functions and expectation values of the unperturbed Hamiltonian are expressed in terms of the spectral determinant of the perturbed Hamiltonian. Semiclassical resummation methods for spectral determinants are applied and yield approximations in terms of a finite number of classical trajectories. The final formulas have a simple form. In contrast to Poincare surface of section methods, the resummation is done in terms of the periods of the trajectories.

Training Strategies to Mitigate Expectancy-Induced Response Bias in Combat Identification: A Research Agenda  

Science Conference Proceedings (OSTI)

Historical assessments of combat fratricide reveal principal contributing factors in the effects of stress, continuous operations or sleep deprivation, poor situational awareness, emotions, and lack of training. This paper discusses what and how improvements in combat identification (CID) may be achieved through training. In addition to skill-based training, CID training must focus on countering the negative effects of expectancy in the face of heightened anxiety and stressors of continuous operations that lead to combat errors or fratricide. The paper examines possible approaches to training for overcoming erroneous expectancies and emotional factors that may distort or limit accurate "blue force" identification.

Understanding Spatio-Temporal Variability and Associated Physical Controls of Near-Surface Soil Moisture in Different Hydro-Climates  

E-Print Network (OSTI)

Near-surface soil moisture is a key state variable of the hydrologic cycle and plays a significant role in the global water and energy balance by affecting several hydrological, ecological, meteorological, geomorphologic, and other natural processes in the land-atmosphere continuum. Presence of soil moisture in the root zone is vital for the crop and plant life cycle. Soil moisture distribution is highly non-linear across time and space. Various geophysical factors (e.g., soil properties, topography, vegetation, and weather/climate) and their interactions control the spatio-temporal evolution of soil moisture at various scales. Understanding these interactions is crucial for the characterization of soil moisture dynamics occurring in the vadose zone. This dissertation focuses on understanding the spatio-temporal variability of near-surface soil moisture and the associated physical control(s) across varying measurement support (point-scale and passive microwave airborne/satellite remote sensing footprint-scale), spatial extents (field-, watershed-, and regional-scale), and changing hydro-climates. Various analysis techniques (e.g., time stability, geostatistics, Empirical Orthogonal Function, and Singular Value Decomposition) have been employed to characterize near-surface soil moisture variability and the role of contributing physical control(s) across space and time. Findings of this study can be helpful in several hydrological research/applications, such as, validation/calibration and downscaling of remote sensing data products, planning and designing effective soil moisture monitoring networks and field campaigns, improving performance of soil moisture retrieval algorithm, flood/drought prediction, climate forecast modeling, and agricultural management practices.

Plasma parameters and electromagnetic forces induced by the magneto hydro dynamic interaction in a hypersonic argon flow experiment  

SciTech Connect

This work proposes an experimental analysis on the magneto hydro dynamic (MHD) interaction induced by a magnetic test body immersed into a hypersonic argon flow. The characteristic plasma parameters are measured. They are related to the voltages arising in the Hall direction and to the variation of the fluid dynamic properties induced by the interaction. The tests have been performed in a hypersonic wind tunnel at Mach 6 and Mach 15. The plasma parameters are measured in the stagnation region in front of the nozzle of the wind tunnel and in the free stream region at the nozzle exit. The test body has a conical shape with the cone axis in the gas flow direction and the cone vertex against the flow. It is placed at the nozzle exit and is equipped with three permanent magnets. In the configuration adopted, the Faraday current flows in a closed loop completely immersed into the plasma of the shock layer. The electric field and the pressure variation due to MHD interaction have been measured on the test body walls. Microwave adsorption measurements have been used for the determination of the electron number density and the electron collision frequency. Continuum recombination radiation and line radiation emissions have been detected. The electron temperature has been determined by means of the spectroscopic data by using different methods. The electron number density has been also determined by means of the Stark broadening of H{sub {alpha}} and the H{sub {beta}} lines. Optical imaging has been utilized to visualize the pattern of the electric current distribution in the shock layer around the test body. The experiments show a considerable effect of the electromagnetic forces produced by the MHD interaction acting on the plasma flow around the test body. A comparison of the experimental data with simulation results shows a good agreement.

The Effect of Price Expectations on Auto-Repair Price Quotes  

E-Print Network (OSTI)

We show that price expectations alter outcomes in a negotiated price environment. By experimentally manipulating the price expectations that consumers communicate to firms, we show that consumers price expectations alter outcomes by directly changing firms behavior. We implement a large-scale field experiment in which callers request price quotes from automotive repair shops. We find that repair shops quote higher prices if they know that callers perception of the market price is high. We find that women are quoted higher prices than men when callers signal that they are uninformed about market prices. However, gender differences disappear when callers mention an expected price for the repair. Finally, we find that repair shops are more likely to offer In an environment in which prices customarily are negotiated, it can be difficult and time-consuming for consumers to gather enough information to create a good estimate of the market price. This phenomenon is common to many industries: buying a car entails lengthy negotiations in which dealers want to know about a consumers current vehicle, her financing preferences, the available

U.S. crude oil production expected to exceed oil imports later this year  

U.S. Energy Information Administration (EIA) Indexed Site

crude oil production expected to exceed oil imports later crude oil production expected to exceed oil imports later this year U.S. crude oil production is expected to surpass U.S. crude oil imports by the fourth quarter of this year. That would mark the first time since February 1995 that domestic crude oil output exceeds imports, according to the latest monthly energy outlook from the U.S. Energy Information Administration. The United States will still need to import crude oil to help meet domestic demand. However, total crude oil imports this year are on track to fall to their lowest level since 1997. U.S. oil production is expected to continue to rise over the next two years as imports fall. As a result, the share of total U.S. petroleum consumption met by net imports is forecast to fall to 32 percent next year, the lowest level since 1985 and nearly half the peak level of 60 percent seen in

Exploring the industrial hygiene academic curriculum: Expectations and perceptions of the profession  

E-Print Network (OSTI)

Although the multi-disciplinary profession of industrial hygiene (IH) has been established for many years and IH practitioners have been prolific in developing the technical tools for recognition, evaluation and control of workplace hazards, few in the IH discipline have turned the tools and methods of academic research toward the academic curriculum itself. A review of the literature revealed that published research in IH curriculum has been minimal, and that none has considered comparing faculty and employer expectations. Evaluating the nature of the current IH curriculum, and the preferences and expectations of the IH profession for graduates competencies, is true to the goal of IH practice, i.e., conducting research as a basis for on-going evaluation and review of existing programs, and using research findings to plan preventive interventions in order to ensure continued good health of both programs and impacted individuals. This research was an initial, exploratory study to identify and assess the expectations and perceptions of the IH faculty and employers in the areas of IH curriculum content and structure. The expectations and perceptions of IH academic program faculty were compared with those of employers of graduates of IH programs. Characteristics of current IH academic programs were identified, as a baseline for future evaluation of the IH curriculum. Actual and expected undergraduate majors of those entering IH masters programs were identified to aid in targeting effective recruitment programs and efficient resource allocation. The study populations skill and capacity with computers and the Internet were assessed as an indicator of readiness to incorporate distance learning methodology and electronic media delivery into traditional classroom delivery of industrial hygiene education. Recommendations were given for model IH curricula derived from the survey participants responses, and for future work.

Moon's Radiation Environment and Expected Performance of Solar Cells during Future Lunar Missions  

E-Print Network (OSTI)

Several lunar missions are planned ahead and there is an increasing demand for efficient photovoltaic power generation in the moon. The knowledge of solar cell operation in the lunar surface obtained during early seventies need to be updated considering current views on solar variability and emerging space solar cell technologies. In this paper some aspects of the solar cell performance expected under variable lunar radiation environment during future space missions to moon are addressed. We have calculated relative power expected from different types of solar cells under extreme solar proton irradiation conditions and high lunar daytime temperature. It is also estimated that 2-3 % of annual solar cell degradation is most probable during the future lunar missions. We have also discussed photovoltaic power generation in long term lunar bases emphasizing technological needs such as sunlight concentration, solar cell cooling and magnetic shielding of radiation for improving the efficiency of solar cells in the lunar environment.

DOE Green Energy (OSTI)

This study was designed to develop and apply methods to evaluate the cumulative effects of 20 proposed small hydro projects on the fisheries resources of the Swan River drainage located in northwestern Montana. Fish population and reach classification information was used to estimate total populations of 107,000 brook trout, 65,000 cut-throat trout and 31,000 juvenile bull trout within the tributary system. Distribution, abundance, and life history of fish species in the drainage and their contribution to the sport fishery were considered in the cumulative impact analysis. Bull trout were chosen as the primary species of concern because of their extensive use of project areas, sensitivity to streambed sedimentation, and their importance to the lake and river sport fisheries. Dewatering of hydroelectric diversion zones and streambed sedimentation (resulting from forest and small hydro development) were the major impacts considered. The developer proposed to divert up to the entire streamflow during low flow months because maintenance of recommended minimum bypass flows would not allow profitable project operation. Dewatering was assumed to result in a total loss of fish production in these areas. 105 refs., 19 figs., 38 tabs.

These specifications are made available by the Department of Energy for the voluntary use by any person, corporation or governmental body in the writing of purchase specifications for the automatic control of small hydro generating stations, i.e., hydro plants ranging in size from 50 kW to 15 MW. It is believed that the use of these specifications will permit competition among capable vendors and, at the same time, assure proper and reliable operation of both the automation hardware and software purchased. The specifications are detailed to a degree which should assure the interchangeability of hardware and software from various suppliers. This also increases the likelihood that spare parts and service will be available for many years. The specifications are written in modules, each of which can be included or excluded for ease of editing to match a particular application. Brief but detailed instructions are included for such editing. An extensive appendix gives the alternatives which were considered and reasons for the various choices specified.

Numerical Modeling of Hydraulic Fracture Propagation Using Thermo-hydro-mechanical Analysis with Brittle Damage Model by Finite Element Method  

E-Print Network (OSTI)

Better understanding and control of crack growth direction during hydraulic fracturing are essential for enhancing productivity of geothermal and petroleum reservoirs. Structural analysis of fracture propagation and impact on fluid flow is a challenging issue because of the complexity of rock properties and physical aspects of rock failure and fracture growth. Realistic interpretation of the complex interactions between rock deformation, fluid flow, heat transfer, and fracture propagation induced by fluid injection is important for fracture network design. In this work, numerical models are developed to simulate rock failure and hydraulic fracture propagation. The influences of rock deformation, fluid flow, and heat transfer on fracturing processes are studied using a coupled thermo-hydro-mechanical (THM) analysis. The models are used to simulate microscopic and macroscopic fracture behaviors of laboratory-scale uniaxial and triaxial experiments on rock using an elastic/brittle damage model considering a stochastic heterogeneity distribution. The constitutive modeling by the energy release rate-based damage evolution allows characterizing brittle rock failure and strength degradation. This approach is then used to simulate the sequential process of heterogeneous rock failures from the initiation of microcracks to the growth of macrocracks. The hydraulic fracturing path, especially for fractures emanating from inclined wellbores and closed natural fractures, often involves mixed mode fracture propagation. Especially, when the fracture is inclined in a 3D stress field, the propagation cannot be modeled using 2D fracture models. Hence, 2D/3D mixed-modes fracture growth from an initially embedded circular crack is studied using the damage mechanics approach implemented in a finite element method. As a practical problem, hydraulic fracturing stimulation often involves fluid pressure change caused by injected fracturing fluid, fluid leakoff, and fracture propagation with brittle rock behavior and stress heterogeneities. In this dissertation, hydraulic fracture propagation is simulated using a coupled fluid flow/diffusion and rock deformation analysis. Later THM analysis is also carried out. The hydraulic forces in extended fractures are solved using a lubrication equation. Using a new moving-boundary element partition methodology (EPM), fracture propagation through heterogeneous media is predicted simply and efficiently. The method allows coupling fluid flow and rock deformation, and fracture propagation using the lubrication equation to solve for the fluid pressure through newly propagating crack paths. Using the proposed model, the 2D/3D hydraulic fracturing simulations are performed to investigate the role of material and rock heterogeneity. Furthermore, in geothermal and petroleum reservoir design, engineers can take advantage of thermal fracturing that occurs when heat transfers between injected flow and the rock matrix to create reservoir permeability. These thermal stresses are calculated using coupled THM analysis and their influence on crack propagation during reservoir stimulation are investigated using damage mechanics and thermal loading algorithms for newly fractured surfaces.

Microbial Gas Generation Under Expected Waste Isolation Pilot Plant Repository Conditions: Final Report  

Science Conference Proceedings (OSTI)

Gas generation from the microbial degradation of the organic constituents of transuranic (TRU) waste under conditions expected in the Waste Isolation Pilot Plant (WIPP) was investigated. The biodegradation of mixed cellulosic materials and electron-beam irradiated plastic and rubber materials (polyethylene, polyvinylchloride, hypalon, leaded hypalon, and neoprene) was examined. We evaluated the effects of environmental variables such as initial atmosphere (air or nitrogen), water content (humid ({approx}70% relative humidity, RH) and brine inundated), and nutrient amendments (nitogen phosphate, yeast extract, and excess nitrate) on microbial gas generation. Total gas production was determined by pressure measurement and carbon dioxide (CO{sub 2}) and methane (CH{sub 4}) were analyzed by gas chromatography; cellulose degradation products in solution were analyzed by high-performance liquid chromatography. Microbial populations in the samples were determined by direct microscopy and molecular analysis. The results of this work are summarized.

Expected Power-Utility Maximization Under Incomplete Information and with Cox-Process Observations  

SciTech Connect

We consider the problem of maximization of expected terminal power utility (risk sensitive criterion). The underlying market model is a regime-switching diffusion model where the regime is determined by an unobservable factor process forming a finite state Markov process. The main novelty is due to the fact that prices are observed and the portfolio is rebalanced only at random times corresponding to a Cox process where the intensity is driven by the unobserved Markovian factor process as well. This leads to a more realistic modeling for many practical situations, like in markets with liquidity restrictions; on the other hand it considerably complicates the problem to the point that traditional methodologies cannot be directly applied. The approach presented here is specific to the power-utility. For log-utilities a different approach is presented in Fujimoto et al. (Preprint, 2012).

WTI Crude Oil Prices Are Expected To Remain Relatively High Through At  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: As we just saw, one of the primary factors impacting gasoline price is the crude oil price. This graph shows monthly average spot West Texas Intermediate crude oil prices. Spot WTI crude oil prices broke $36 per barrel in November briefly as anticipated boosts to world supply from OPEC and other sources did not show up in actual stocks data. Crude oil prices are expected to be about $30 per barrel for the rest of this year, but note the uncertainty bands on this projection. They give an indication of how difficult it is to know what these prices are going to do. Also, EIA does not forecast volatility. This relatively flat forecast could be correct on average, with wide swings around the base line. With the EIA forecast for crude prices staying high this year,

Effects of microbial processes on gas generation under expected WIPP repository conditions: Annual report through 1992  

Science Conference Proceedings (OSTI)

Microbial processes involved in gas generation from degradation of the organic constituents of transuranic waste under conditions expected at the Waste Isolation Pilot Plant (WIPP) repository are being investigated at Brookhaven National Laboratory. These laboratory studies are part of the Sandia National Laboratories -- WIPP Gas Generation Program. Gas generation due to microbial degradation of representative cellulosic waste was investigated in short-term ( 6 months) experiments by incubating representative paper (filter paper, paper towels, and tissue) in WIPP brine under initially aerobic (air) and anaerobic (nitrogen) conditions. Samples from the WIPP surficial environment and underground workings harbor gas-producing halophilic microorganisms, the activities of which were studied in short-term experiments. The microorganisms metabolized a variety of organic compounds including cellulose under aerobic, anaerobic, and denitrifying conditions. In long-term experiments, the effects of added nutrients (trace amounts of ammonium nitrate, phosphate, and yeast extract), no nutrients, and nutrients plus excess nitrate on gas production from cellulose degradation.

U.S. average gasoline and diesel fuel prices expected to be slightly lower in 2013 than in 2012  

U.S. Energy Information Administration (EIA) Indexed Site

average gasoline and diesel fuel prices expected to be average gasoline and diesel fuel prices expected to be slightly lower in 2013 than in 2012 Despite the recent run-up in gasoline prices, the U.S. Energy Information Administration expects falling crude oil prices will lead to a small decline in average motor fuel costs this year compared with last year. The price for regular gasoline is expected to average $3.55 a gallon in 2013 and $3.39 next year, according to EIA's new Short-Term Energy Outlook. That's down from $3.63 a gallon in 2012. For the short-term, however, pump prices are expected to peak at $3.73 per gallon in May because of higher seasonal fuel demand and refiners switching their production to make cleaner burning gasoline for the summer. Diesel fuel will continue to cost more than gasoline because of strong global demand for diesel.

Organ sample generator for expected treatment dose construction and adaptive inverse planning optimization  

Science Conference Proceedings (OSTI)

Purpose: To create an organ sample generator (OSG) for expected treatment dose construction and adaptive inverse planning optimization. The OSG generates random samples of organs of interest from a distribution obeying the patient specific organ variation probability density function (PDF) during the course of adaptive radiotherapy. Methods: Principle component analysis (PCA) and a time-varying least-squares regression (LSR) method were used on patient specific geometric variations of organs of interest manifested on multiple daily volumetric images obtained during the treatment course. The construction of the OSG includes the determination of eigenvectors of the organ variation using PCA, and the determination of the corresponding coefficients using time-varying LSR. The coefficients can be either random variables or random functions of the elapsed treatment days depending on the characteristics of organ variation as a stationary or a nonstationary random process. The LSR method with time-varying weighting parameters was applied to the precollected daily volumetric images to determine the function form of the coefficients. Eleven h and n cancer patients with 30 daily cone beam CT images each were included in the evaluation of the OSG. The evaluation was performed using a total of 18 organs of interest, including 15 organs at risk and 3 targets. Results: Geometric variations of organs of interest during h and n cancer radiotherapy can be represented using the first 3 {approx} 4 eigenvectors. These eigenvectors were variable during treatment, and need to be updated using new daily images obtained during the treatment course. The OSG generates random samples of organs of interest from the estimated organ variation PDF of the individual. The accuracy of the estimated PDF can be improved recursively using extra daily image feedback during the treatment course. The average deviations in the estimation of the mean and standard deviation of the organ variation PDF for h and n cancer radiotherapy were less than 2 and 1 mm, respectively, for most organs after the second week of treatment. After the first three weeks of treatment, the mean discrepancy of the dose estimation accuracy was within 1% for most of organs, the corresponding standard deviation was within 2.5% for parotids, the brain stem and the cochleae, and within 1% for other organs. Conclusions: A patient specific OSG is feasible and can be used to generate random samples of organs of interest for the expected treatment dose construction and adaptive inverse planning. The accuracy of the OSG can be improved continuously and recursively during the adaptive treatment course using daily volumetric image feedback.

Silicon detectors for the next generation of high energy physics experiments: expected degradation  

E-Print Network (OSTI)

There exists an enormous interest for the study of very high energy domain in particle physics, both theoretically and experimentally, in the aim to construct a general theory of the fundamental constituents of matter and of their interactions. Until now, semiconductor detectors have widely been used in modern high energy physics experiments. They are elements of the high resolution vertex and tracking system, as well as of calorimeters. The main motivation of this work is to discuss how to prepare some possible detectors - only silicon option being considered, for the new era of HEP challenges because the bulk displacement damage in the detector, consequence of irradiation, produces effects at the device level that limit their long time utilisation, increasing the leakage current and the depletion voltage, eventually up to breakdown, and thus affecting the lifetime of detector systems. In this paper, physical phenomena that conduce to the degradation of the detector are discussed and effects are analysed at the device level (leakage current and effective carrier concentration) in the radiation environments expected in the next generation of hadron colliders after LHC, at the next lepton and gamma-gamma colliders, as well as in astroparticle experiments, in conditions of long time continuum irradiations, for different technological options. The predicted results permit a better decision to obtain devices with harder parameters to radiation.

Damage-expectancy uncertainties for deeply buried targets. Technical report 1 Jan-10 Jul 89  

SciTech Connect

This targeting uncertainties methodology quantifies the effect of systematic errors on the targeting prediction measure damage expectancy. The methodology, developed specifically to support the SEPW Phase 2 Study, evaluates and ranks the effect of uncertainties for applications involving a single buried target and a single earth penetrating weapon. This methodology models the penetration of the EPW, the ground shock environment, and the probability of damage to the underground target. Potential error sources treated in the methodology are impact velocity, geology, depth of burst, target hardness, ground shock prediction model, ground shock depth-to-effect, weapon aiming accuracy, distance damage prediction model, and target depth, location and size. The methodology makes minimal use of assumed distributions and Monte Carlo techniques; instead it uses three points to describe the inherent dispersion for all but one error source. The values are sorted and used to define a distribution for DE. In addition, and analysis of variance technique is used to calculate the relative contributions of each error source to the uncertainty in DE. The added benefit of ranking the error sources in terms of their contribution to the uncertainty in DE can provide insight into deeply buried targeting problems.

First laboratory perforating tests in coal show lower-than-expected penetration  

Science Conference Proceedings (OSTI)

Worldwide Coal Bed Methane (CBM) resources are huge, estimated at 3,000 to 9,000 Tcf. The production rate from CBM reservoirs is low, perhaps 50-100 mcf/day. Various completion methods are being evaluated and new technologies are being developed with the aim of increasing production rates. Considering this interest and activity level, little attention has been paid to the CBM completion fundamentals. Perforating is a critical part of this process, especially considering the PRB development migration from single-coal, open-hole completions into multi-zone, cased-hole completions. This paper describes the first known laboratory-testing program to investigate shaped charge penetration in coal targets. We describe mechanical properties of the coals tested, and penetration results for different shaped charges (of different designs), shot at various stress conditions. CT scan and cutaway imaging of the perforation tunnels are also discussed. Tests were conducted under dry and saturated conditions. The preliminary experiments reported here indicate that shaped charge penetration in coal is significantly less than expected, considering the target's density and strength. The authors provide insight into what may be the reasons for these unexpected results and recommend a path forward for shaped charge testing, designs, predictive tools, and how to optimize CBM completions.

Analysis of past and expected future trends in U. S. energy consumption, 1947--2000  

SciTech Connect

In the first part of this paper, energy consumption trends to the year 2000 are estimated for 110 different industrial sectors and for household and government final demand sectors, and these trends are compared with historical 1947-to-1967 trends. For most sectors, energy consumption is expected to increase much less rapidly in the 1967-1985 period than it did in the 1947-1967 period as a result of the recent large energy price increases. Between 1985 and 2000, the rate of growth of energy consumption continues to moderate for most purchasing sectors primarily because of a slackening in output growth rates rather than because of any further decrease in per unit of output energy requirements. These future trends are estimated under the assumption that post-1976 energy price increases will be moderate. In the second part of the paper, alternative strategies for further reducing future energy consumption are considered, and a data base is presented for use in analyzing the effects of implementing the alternative strategies.

Fatigue expectations in a molybdenum/silicon multilayer under pulsed soft X-ray radiation  

Science Conference Proceedings (OSTI)

The temperature rise in a Mo/a-Si multilayer x-ray reflective film due to radiation absorption is modeled for the first condenser mirror in a projection lithography system such as the one designed by the Advanced Microtechnology Program at LLNL. The radiation load is pulsed at 1000 Hz with a time average intensity of 500mW/cm{sup 2}. This intensity is the expected maximum on the first condenser mirror. The temperature rise is calculated using the integral transform technique. The film is assumed to have the thermal properties of its poorly conducting substrate, yielding a more conservative (higher) temperature estimate. The surface temperature rise is found to range between 35.6{degrees}C and 76.3{degrees}C. The stress due to this rise is greatest in the molybdenum film and ranges between 73MPa and 166MPa compressive. This fluctuating stress level, however, is believed to be insufficient, by a factor of five or so, to cause fatigue failure of the film.

Expected environments in high-level nuclear waste and spent fuel repositories in salt  

SciTech Connect

The purpose of this report is to describe the expected environments associated with high-level waste (HLW) and spent fuel (SF) repositories in salt formations. These environments include the thermal, fluid, pressure, brine chemistry, and radiation fields predicted for the repository conceptual designs. In this study, it is assumed that the repository will be a room and pillar mine in a rock-salt formation, with the disposal horizon located approx. 2000 ft (610 m) below the surface of the earth. Canistered waste packages containing HLW in a solid matrix or SF elements are emplaced in vertical holes in the floor of the rooms. The emplacement holes are backfilled with crushed salt or other material and sealed at some later time. Sensitivity studies are presented to show the effect of changing the areal heat load, the canister heat load, the barrier material and thickness, ventilation of the storage room, and adding a second row to the emplacement configuration. The calculated thermal environment is used as input for brine migration calculations. The vapor and gas pressure will gradually attain the lithostatic pressure in a sealed repository. In the unlikely event that an emplacement hole will become sealed in relatively early years, the vapor space pressure was calculated for three scenarios (i.e., no hole closure - no backfill, no hole closure - backfill, and hole closure - no backfill). It was assumed that the gas in the system consisted of air and water vapor in equilibrium with brine. A computer code (REPRESS) was developed assuming that these changes occur slowly (equilibrium conditions). The brine chemical environment is outlined in terms of brine chemistry, corrosion, and compositions. The nuclear radiation environment emphasized in this report is the stored energy that can be released as a result of radiation damage or crystal dislocations within crystal lattices.

The hydro(solvo)thermal self-assembles of CuI, KI and 2,5-dicarboxylpyridine [2,5-(COOH){sub 2}py] in different molar ratios in H{sub 2}O/alcohol solutions produced three Cu coordination polymers as 2-D [N-C{sub 2}H{sub 5}py][Cu{sub 3}I{sub 4}] 1, 1-D [N-CH{sub 3}py][Cu{sub 2}I{sub 3}] 2 as well as 1-D [Cu(2-COOpy){sub 2}]{center_dot}H{sub 2}O 3 (N-C{sub 2}H{sub 5}py=N-ethylpyridine, N-CH{sub 3}py=N-methylpyridine, 2-COOpy=2-carboxylpyridine). N-C{sub 2}H{sub 5}py in 1 and N-CH{sub 3}py in 2 derived from the solvothermal in situ simultaneous decarboxylation and N-alkylation reactions of 2,5-(COOH){sub 2}py. The semi-decarboxylation reaction of 2,5-(COOH){sub 2}py into 2-COOpy occurred in the preparation of 3.

Compound 3 is a divalent Cu compound. The Cu(II) centers with a 4+2 geometry are coordinated by {mu}{sub 3}-mode 2-COOpy ligands. All of the title compounds were characterized by CHN analysis, IR spectrum analysis and TG analysis.

Hydro-Gravitational-Dynamics Interpretation of the Tadpole VV29 Merging Galaxy System: Dark-Matter-Halo-Planet Star-Cluster Wakes  

E-Print Network (OSTI)

Hubble Space telescope (HST) images of merging galaxy system VV29 reveal the 0.3 Mpc baryonic-dark-matter (BDM) halo composed of primordial protoglobularstarcluster (PGC) clumps of planets. Star-cluster-wakes trace the merger by formation of stars from the planets. Aligned young globular star clusters (YGCs), star-wakes and dust-trails show the frictional, spiral passage of galaxy fragments VV29cdef in a long tail-like galaxy (VV29b) as the fragments merge on the accretion disk plane of the central spiral galaxy VV29a. The observations confirm the hydro-gravitational-dynamics (HGD) prediction of Gibson 1996 and quasar microlensing inference of Schild 1996 that the dark matter of galaxies is dominated by planets (PFPs) in million-solar-mass clumps. Globular star clusters (YGCs, OGCs, PGCs) preserve the density of the plasma epoch 30,000 years after the big bang when viscous supercluster-fragmentation began. Tadpole images show linear galaxy clusters reflecting turbulent vortex lines of protogalaxy fragmentation at the 0.003 Mpc Kolmogorov-Nomura scale of the plasma before transition to gas. The halo size indicates strong diffusion of PGC primordial-planet-clumps from a cooling protogalaxy as its planets freeze.

Water energy resource sites identified in the resource assessment study reported in Water Energy Resources of the United States with Emphasis on Low Head/Low Power Resources, DOE/ID-11111, April 2004 were evaluated to identify which could feasibly be developed using a set of feasibility criteria. The gross power potential of the sites estimated in the previous study was refined to determine the realistic hydropower potential of the sites using a set of development criteria assuming they are developed as low power (less than 1 MW) or small hydro (between 1 and 30 MW) projects. The methodologies for performing the feasibility assessment and estimating hydropower potential are described. The results for the country in terms of the number of feasible sites, their total gross power potential, and their total hydropower potential are presented. The spatial distribution of the feasible potential projects is presented on maps of the conterminous U.S. and Alaska and Hawaii. Results summaries for each of the 50 states are presented in an appendix.

Cool storage technology can be used to significantly reduce energy costs by allowing energy intensive, electrically driven cooling equipment to be predominantly operated during off-peak hours when electricity rates are lower. In addition, some system configurations may result in lower first costs and/or lower operating costs. Cool storage systems of one type or another could potentially be cost-effectively applied in most buildings with a space cooling system. A survey of approximately 25 manufacturers providing cool storage systems or components identified several thousand current installations, but less than 1% of these were at Federal facilities. With the Federal sector representing nearly 4% of commercial building floor space and 5% of commercial building energy use, Federal utilization would appear to be lagging. Although current applications are relatively few, the estimated potential annual savings from using cool storage in the Federal sector is $50 million. There are many different types of cool storage systems representing different combinations of storage media, charging mechanisms, and discharging mechanisms. The basic media options are water, ice, and eutectic salts. Ice systems can be further broken down into ice harvesting, ice-on-coil, ice slurry, and encapsulated ice options. Ice-on-coil systems may be internal melt or external melt and may be charged and discharged with refrigerant or a single-phase coolant (typically a water/glycol mixture). Independent of the technology choice, cool storage systems can be designed to provide full storage or partial storage, with load-leveling and demand-limiting options for partial storage. Finally, storage systems can be operated on a chiller-priority or storage priority basis whenever the cooling load is less than the design conditions. The first section describes the basic types of cool storage technologies and cooling system integration options. The next three sections define the savings potential in the Federal sector, present application advice, and describe the performance experience of specific Federal users. A step-by-step methodology illustrating how to evaluate cool storage options is presented next, followed by a case study of a GSA building using cool storage. Latter sections list manufacturers, selected Federal users, and reference materials. Finally, the appendixes give Federal life-cycle costing procedures and results for a case study.

Contribution from the interaction Hamiltonian to the expectation value of particle number with the non-equilibrium quantum field theory  

SciTech Connect

We develop the method analyzing particle number non-conserving phenomena with non-equilibrium quantum field-theory. In this study, we consider a CP violating model with interaction Hamiltonian that breaks particle number conservation. To derive the quantum Boltzmann equation for the particle number, we solve Schwinger-Dyson equation, which are obtained from two particle irreducible closed-time-path (2PI CTP) effective action. In this calculation, we show the contribution from interaction Hamiltonian to the time evolution of expectation value of particle number.

The first objective listed on page 2 of the draft engagement plan states that the stakeholder engagements goal is to provide stakeholders the opportunity to provide feedback to MACD on their business needs around the auditing process (e.g. audit preparation materials, timing of deadlines, etc). However, on page 1 of the plan, items such as evidentiary requirements and disclosure of audit results are listed as Out of Scope. Hydro One submits that these items and others are important parts of the audit process and should be discussed and agreed on so Ontario entities can prepare accordingly. 2. The last bullet in the Terms of Reference document states that the Working Group is meant to provide advice and as a result consensus is not a goal of the engagement. Hydro One submits that, considering that Market Rule amendments will need to be in place (including Stakeholders Engagement, Technical Panel and IESO Board of Directors approval) to allow MACD to proceed with audit activities in Ontario, the RSAWG is the appropriate group to discuss and reach

Load controller and method to enhance effective capacity of a photovotaic power supply using a dynamically determined expected peak loading  

DOE Patents (OSTI)

A load controller and method are provided for maximizing effective capacity of a non-controllable, renewable power supply coupled to a variable electrical load also coupled to a conventional power grid. Effective capacity is enhanced by monitoring power output of the renewable supply and loading, and comparing the loading against the power output and a load adjustment threshold determined from an expected peak loading. A value for a load adjustment parameter is calculated by subtracting the renewable supply output and the load adjustment parameter from the current load. This value is then employed to control the variable load in an amount proportional to the value of the load control parameter when the parameter is within a predefined range. By so controlling the load, the effective capacity of the non-controllable, renewable power supply is increased without any attempt at operational feedback control of the renewable supply. The expected peak loading of the variable load can be dynamically determined within a defined time interval with reference to variations in the variable load.

Irradiation Tests and Expected Performance of Readout Electronics of the ATLAS Hadronic Endcap Calorimeter for the HL-LHC  

E-Print Network (OSTI)

The readout electronics of the ATLAS Hadronic Endcap Calorimeter (HEC) will have to withstand an about 3-5 times larger radiation environment at the future high-luminosity LHC (HLLHC) compared to their design values. The preamplifier and summing boards (PSBs), which are equipped with GaAs ASICs and comprise the heart of the readout electronics, were irradiated with neutrons and protons with fluences surpassing several times ten years of operation of the HL-LHC. Neutron tests were performed at the NPI in Rez, Czech Republic, where a 36 MeV proton beam was directed on a thick heavy water target to produce neutrons. The proton irradiation was done with 200 MeV protons at the PROSCAN area of the Proton Irradiation Facility at the PSI in Villigen, Switzerland. In-situ measurements of S-parameters in both tests allow the evaluation of frequency dependent performance parameters, like gain and input impedance, as a function of fluence. The linearity of the ASIC response was measured directly in the neutron tests with a triangular input pulse of varying amplitude. The results obtained allow an estimation of the expected performance degradation of the HEC. For a possible replacement of the PSB chips, alternative technologies were investigated and exposed to similar neutron radiation levels. In particular, IHP 250 nm Si CMOS technology has turned out to show good performance and match the specifications required. The performance measurements of the current PSB devices, the expected performance degradations under HL-LHC conditions, and results from alternative technologies will be presented.

CALCULATION OF THE SAFE LIFE TIME EXPECTANCY OF ZIRCONIUM ALLOY CANNING IN THE FUEL ELEMENTS OF THE NERO REACTOR  

DOE Green Energy (OSTI)

Based on the present day knowledge of the oxidation and hydridation behaviour of Zirconium alloys under PWR conditions, a calculation of the safe life time expectancy of Zirconium alloy canning in the fuel elements of the NERO reactor is presented. The decisive NERO conditions for life time calculations are a heat flow of 100 W/cm {sup 2} and a temperature of 345 deg C at the oxide-water surface. The calculations take account of the increase in oxidation rate under the influence of the heat flow and of the distribution of absorbed hydrogen in the canning wall in the radial direction. The maximum tolerable oxide or oxide + hydride layer thickness, on Zirconium alloy canning tubes was fixed at 35 {mu}. The calculated data led to the conclusion that from the corrosion point of view, the safe life time of Zirconium alloy canning tubes, having a wall thickness of 0.85 mm, operating under NERO conditions is 2.40 years for Zircaloy-2, 3.40 years for Zr-2% Nb and Zr-3% Sn, and 3.60 years for Zircaloy-4.

Addiction: Decreased reward sensitivity and increased expectation sensitivity conspire to overwhelm the brains control circuit  

SciTech Connect

Based on brain imaging findings, we present a model according to which addiction emerges as an imbalance in the information processing and integration among various brain circuits and functions. The dysfunctions reflect (a) decreased sensitivity of reward circuits, (b) enhanced sensitivity of memory circuits to conditioned expectations to drugs and drug cues, stress reactivity, and (c) negative mood, and a weakened control circuit. Although initial experimentation with a drug of abuse is largely a voluntary behavior, continued drug use can eventually impair neuronal circuits in the brain that are involved in free will, turning drug use into an automatic compulsive behavior. The ability of addictive drugs to co-opt neurotransmitter signals between neurons (including dopamine, glutamate, and GABA) modifies the function of different neuronal circuits, which begin to falter at different stages of an addiction trajectory. Upon exposure to the drug, drug cues or stress this results in unrestrained hyperactivation of the motivation/drive circuit that results in the compulsive drug intake that characterizes addiction.

A characterization of robust radiation therapy treatment planning methods-from expected value to worst case optimization  

SciTech Connect

Purpose: To characterize a class of optimization formulations used to handle systematic and random errors in radiation therapy, and to study the differences between the methods within this class. Methods: The class of robust methods that can be formulated as minimax stochastic programs is studied. This class generalizes many previously used methods, ranging between optimization of the expected and the worst case objective value. The robust methods are used to plan intensity-modulated proton therapy (IMPT) treatments for a case subject to systematic setup and range errors, random setup errors with and without uncertain probability distribution, and combinations thereof. As reference, plans resulting from a conventional method that uses a margin to account for errors are shown. Results: For all types of errors, target coverage robustness increased with the conservativeness of the method. For systematic errors, best case organ at risk (OAR) doses increased and worst case doses decreased with the conservativeness. Accounting for random errors of fixed probability distribution resulted in heterogeneous dose. The heterogeneities were reduced when uncertainty in the probability distribution was accounted for. Doing so, the OAR doses decreased with the conservativeness. All robust methods studied resulted in more robust target coverage and lower OAR doses than the conventional method. Conclusions: Accounting for uncertainties is essential to ensure plan quality in complex radiation therapy such as IMPT. The utilization of more information than conventional in the optimization can lead to robust target coverage and low OAR doses. Increased target coverage robustness can be achieved by more conservative methods.

Aerosol Properties from Multi-spectral and Multi-angular Aircraft 4STAR Observations: Expected Advantages and Challenges  

SciTech Connect

The airborne Spectrometer for Sky-Scanning, Sun-Tracking Atmospheric Research (4STAR) is developed to retrieve aerosol microphysical and optical properties from multi-angular and multi-spectral measurements of sky radiance and direct-beam sun transmittance. The necessarily compact design of the 4STAR may cause noticeable apparent enhancement of sky radiance at small scattering angles. We assess the sensitivity of expected 4STAR-based aerosol retrieval to such enhancement by applying the operational AERONET retrieval code and constructed synthetic 4STARlike data. Also, we assess the sensitivity of the broadband fluxes and the direct aerosol radiative forcing to uncertainties in aerosol retrievals associated with the sky radiance enhancement. Our sensitivity study results suggest that the 4STARbased aerosol retrieval has limitations in obtaining detailed information on particle size distribution and scattering phase function. However, these limitations have small impact on the retrieved bulk optical parameters, such as the asymmetry factor (up to 4%, or 0.02) and single-scattering albedo (up to 2%, or 0.02), and the calculated direct aerosol radiative forcing (up to 6%, or 2 Wm-2).

Draft environmental impact statement for construction and operation of the proposed Bangor Hydro-Electric Company`s second 345-kV transmission tie line to New Brunswick  

Science Conference Proceedings (OSTI)

This Draft Environmental Impact Statement (DEIS) was prepared by the US Department of Energy (US DOE). The proposed action is the issuance of Presidential Permit PP-89 by DOE to Bangor Hydro-Electric Company to construct and operate a new international transmission line interconnection to New Brunswick, Canada that would consist of an 83.8 mile (US portion), 345-kilovolt (kV) alternating current transmission line from the US-Canadian border at Baileyville, Maine to an existing substation at Orrington, Maine. The principal environmental impacts of the construction and operation of the transmission line would be incremental in nature and would include the conversion of forested uplands (mostly commercial timberlands) and wetlands to right-of-way (small trees, shrubs, and herbaceous vegetation). The proposed line would also result in localized minor to moderate visual impacts and would contribute a minor incremental increase in the exposure of some individuals to electromagnetic fields. This DEIS documents the purpose and need for the proposed action, describes the proposed action and alternatives considered and provides a comparison of the proposed and alternatives routes, and provides detailed information on analyses of the environmental consequences of the proposed action and alternatives, as well as mitigative measures to minimize impacts.

FEMAXI-V benchmarking study on peak temperature and fission gas release prediction of PWR rod fuel  

Science Conference Proceedings (OSTI)

The present paper reports a study of FEMAXI-V code and related report on code benchmarking. Capabilities of the FEMAXI-V code to predict the thermal and fission gas release have been tested on MOX fuels in LWRs which has been done in SCK{center_dot}CEN and Belgonucleaire by using PRIMO MOX rod BD8 irradiation experiment after V Sobolev as reported O. J. Ott. Base irradiation in the BR3 reactor, the BD8 rod was transported to CEA-Saclay for irradiation in the OSIRIS reactor (ramp power excursion). The irradiation device used for the PRIMO ramps was the ISABELLE 1 loop, installed on a movable structure of the core periphery. The power variations were obtained by inwards/backwards movements of the loop in the core water. The preconditioning phase for rod BD8 occurred at a peak power level of 189 W/cm with a hold time of 27 hours. The subsequent power excursion rate amounted to 77 W/ (cm.min), reaching a terminal peak power level of 395 W/cm that lasted for 20 hours.

Calculation of the expectation values of the spin and the magnetic moment of the gamma photons created as a result of the electron-positron annihilation  

E-Print Network (OSTI)

We have calculated the expectation values of the spin and the intrinsic magnetic moment of the gamma photons created as a result of the electron-positron annihilation. We show that, depending on its helicity a gamma photon propagating in z direction with an angular frequency carries a magnetic moment of along the propagation direction. Here the (+) and (-) signs stand for the right hand and left circular helicity respectively. We also show that whatever the helicity is, the spin of each gamma photon is equal to zero (but not !). We argue that in a Stern-Gerlach experiment (SGE) the magnetic moment is an important property but not the spin of the particles. Because of these two symmetric values of the magnetic moment, we expect a splitting of the gamma photon beam into two symmetric subbeams in a (SGE). We believe that the present result will be helpful for understanding the recent attempts on the (SGE) with slow light and the behavior of the dark polaritons and also the atomic spinor polaritons.

Hydro-flow supra-turbine engine  

SciTech Connect

A turbine engine operates at high pressure and at relatively low temperatures and revolutions per minute through the use of special carburetion, compressor, combustion unit, and turbine arrangements. The system is characterized by the use of water which is vaporized and concurrently reduces the temperature of the vaporized fuel and air mixture as compression occurs, and is not physically intermixed with the combustion gases until after initial combustion takes place. The compressor includes a pair of back-to-back, four stage composite compressors to which synchronized dual carburetion or meter-flow arrangements separately supply water and gasoline or other fuel, along with air. The water absorbs heat from the compression of both of the two compressors, and the resultant vaporous product gases are routed to the jacket of a combustion chamber in which the compressed fuel and air mixture is burned. Following initial ignition and some burning of the fuel, the superheated steam and combustion products are combined, and the combination is supplied to a multistage transverse flow turbine having in the order of 17 pressure stages. The turbine includes arrangements for directing the high pressure gases back and forth through the rotor blades at different radial distances from the axis of the turbine. Exhaust gases from the turbine are applied to a ''floating'' muffler, including a rotatable inner chamber to facilitate mixing exhaust gases with the ambient air, and to disperse the high moisture content of the exhaust gases.

Helicity in Hydro and MHD Reconnection  

E-Print Network (OSTI)

Helicity, a measure of the linkage of flux lines, has subtle and largely unknown effects upon dynamics. Both magnetic and hydrodynamic helicity are conserved for ideal systems and could suppress nonlinear dynamics. What actually happens is not clear because in a fully three-dimensional system there are additional channels whereby intense, small-scale dynamics can occur. This contribution shows one magnetic and one hydrodynamic case where for each the presence of helicity does not suppress small-scale intense dynamics of the type that might lead to reconnection.

The second act of hydro: small perturbations  

E-Print Network (OSTI)

Hydrodynamical description of the "Little Bang" in heavy ion collisions is surprisingly successful: here we systematically study propagation of small perturbations %, also treated hydrodynamically. Using analytic description of the expanding fireball known as the "Gubser flow", we proceed to linearized equations for perturbations. As all variables are separated and all equations solved (semi)analytically, we can collect all the harmonics and reconstruct the complete Green function of the problem, even in the viscous case. Applying it to the power spectrum we found acoustic minimum at the $m=7$ and maximum at $m=9$, which remarkably have some evidence for both in the data. We estimate effective viscosity and size of the perturbation from a fit to power spectrum. The shape of the two-point correlator is also reproduced remarcably well. At the end we argue that independent perturbations are local, and thus harmonics phases are correlated.

Hydro static water level systems at Fermilab  

Science Conference Proceedings (OSTI)

Several Hydrostatic Water Leveling systems (HLS) are in use at Fermilab. Three systems are used to monitor quadrupoles in the Tevatron and two systems are used to monitor ground motion for potential sites for the International Linear Collider (ILC). All systems use capacitive sensors to determine the water level of water in a pool. These pools are connected with tubing so that relative vertical shifts between sensors can be determined. There are low beta quadrupoles at the B0 and D0 interaction regions of Tevatron accelerator. These quadrupoles use BINP designed and built sensors and have a resolution of 1 micron. All regular lattice superconducting quadrupoles (a total of 204) in the Tevatron use a Fermilab designed system and have a resolution of 6 microns. Data on quadrupole motion due to quenches, changes in temperature will be presented. In addition data for ground motion for ILC studies caused by natural and cultural factors will be presented.

Galaxy formation from dry and hydro simulations  

E-Print Network (OSTI)

The effects of dry and wet merging on the Scaling Laws (SLs) of elliptical galaxies (Es) are discussed. It is found that the galaxy SLs, possibly established at high redshift by the fast collapse of gas-rich and clumpy stellar distributions in preexisting dark matter halos following the cosmological SLs, are compatible with a (small) number of galaxy mergers at lower redshift.

Old Harbor Scammon Bay Hydro Feasibility  

DOE Green Energy (OSTI)

The grantee, Alaska Village Electric Cooperative (AVEC), is a non-profit member owned rural electric generation and distribution cooperative. The proposed Project is located near the community of Old Harbor, Alaska. Old Harbor is on the southeastern coast of Kodiak Island, approximately 70 miles southwest of the City of Kodiak and 320 miles southwest of Anchorage. In 1998 sufficient information had been developed to apply for a license to construct the project and the cost was estimated to be $2,445,000 for a 500 KW project on Lagoon Creek. Major features of the project included an eight-foot high diversion dam on Mountain Creek, a desander box, a 9,800-foot long penstock to the powerhouse on Lagoon Creek, and a 5,500-foot long access road. It was also anticipated that the project could provide an additional source of water to Old Harbor. The report details the history and lessons learned in designing and permiting the proposed hydroelectric facility.

Hydro-without-Hydro Framework for Simulations of Black Hole-Neutron Star Binaries  

E-Print Network (OSTI)

We introduce a computational framework which avoids solving explicitly hydrodynamic equations and is suitable to study the pre-merger evolution of black hole-neutron star binary systems. The essence of the method consists of constructing a neutron star model with a black hole companion and freezing the internal degrees of freedom of the neutron star during the course of the evolution of the space-time geometry. We present the main ingredients of the framework, from the formulation of the problem to the appropriate computational techniques to study these binary systems. In addition, we present numerical results of the construction of initial data sets and evolutions that demonstrate the feasibility of this approach.

Distillate Stocks Expected to Remain Low  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: When EIA's demand forecast is combined with its outlook for production and net imports, distillate stocks are projected to remain low for the rest of the year. - Stocks are beginning at very low levels. The September 1 distillate fuel stock level (112 million barrels) is nearly 20% less than last year, and about 15% below the 10 year average for end of August levels. - But stocks on the East Coast, at 39.8 million barrels, are 39% behind year-ago levels, and about a similar percentage below end-of-August 10-year average levels. Over the last 10 years, the average stock build from the end of August through the end of November has been about 10 million barrels. We are forecasting about a 12 million barrel build, which does not reach the normal band. Forecast stocks peak at the end of November at 127 million

Higher price expectations are spurring optimism  

Science Conference Proceedings (OSTI)

This article reports on some encouraging developments for industry in the '80s despite one of the most sever price downturns in the history of the business. The 1970s were characterized by a boom solely led by price increases. The 1990:0090s should see some price growth and profitability caused by efficiency. Technologies such as 3-D seismic and horizontal drilling will allow the U.S. and other high cost areas to once again expand activity in the oil patch. While the 1980s can be viewed as one of industry's most trying times, many advances in technology funded during boom years came and are coming to fruition. Finding, developing and producing reserves at the lowest possible cost will be the theme of the '90s if the U.S. oil and gas business and other high cost countries are to stay in the game. Advancements in drilling and completion technology for horizontal wells is an excellent case in point. Multiple developments in MWD, logging, tubing-conveyed or drill sting-conveyed systems, underbalanced drilling techniques, moving equipment around tight angles, and many other developments have made horizontal drilling the in subject of today. Formations like the Austin Chalk in Texas may finally be economic despite failures of vertical wells, even in the boom times. While no panacea, horizontal drilling has the potential for improving per well productivities in many environments.

Washington in `97: Positive energy moves expected  

Science Conference Proceedings (OSTI)

After the stormy closing weeks of the 1996 electrons, when the fog finally lifted, a strong indication of the direction American politics is taking emerged. It is still moving clearly to the right. Donald Lambro, chief political correspondent of The Washington Times, put it this way, ``Contemporary liberalism may not be dead and buried yet, but it remains comatose and continues to wither away--without a clear and relevant agenda, without a credible champion, and without a majority party. Meanwhile, the Congress that will be sworn in next January will be one of the most conservative in decades.`` Why that will likely bode well for the US oil and gas industry is the theme of the following discussion. Outlined therein are: some thoughts on why Clinton won; a wrapup of key seats and committee members of the 105th Congress; news of a bipartisan forum for the oil/gas industry; improved outlook for movement on the Arctic National Wildlife Refuge (ANWR); progress on the national public education program; and a list of industry`s challenges for the next few years.
