The Near-Term Product Development Project  

SciTech Connect (OSTI)

Since 1990, the US Department of Energy (DOE) and members of the US wind industry have been working as partners to development advanced, highly efficient wind turbines. The overall goal of these partnerships is to develop turbines that can complete successfully in the world`s utility markets for low-cost electricity. The cost goal is to produce electricity at or below $0.05/kWh in moderate winds. Moderate winds (6.9 mps [15.4 mph] at hub heights) prevail in large expanses of the Great Plains, where much of the vast wind resources of this country are located. Under the Near-Term Product Development Project, begun in 1992, several US companies are building and testing turbine prototypes.

V V E R C O M I N G P L A N T R E C A L C I T R A N C E Supercomputers Tackle BIOFUEL Production Problems If you have ever dealt with an uncooperative, fractious kid or a combative employee, you understand the meaning of "recalcitrance" - over-the-top stubbornness, disobedience, and noncompliance. But recalcitrance is not just a human trait - plants can be recalcitrant, too, and for them it is a matter of survival. Over millions of years, plants have evolved complex structural and chemical mechanisms to ward off assaults on their structural sugars by microbial and animal marauders. So it should be no surprise that when humans attempt to turn plant biomass into biofuels to meet our energy needs, we discover how stubborn and noncompliant our vegetative friends can be. Plant recalcitrance is one of

Russian metallurgical coal supplies. A near-term perspective  

SciTech Connect (OSTI)

Calculations were made to estimate the changes in metallurgical coal supplies during the next 10 years. These calculations are based on three sets of data for the forecast period: (1) estimated changes in production at existing coal production and cleaning facilities in Kuznetsk, Pechora, and South Yakutsk basins; (2) production from new facilities as stipulated in licensing agreements for metallurgical coal production; and (3) Russian output of coke and washed coals. Estimates are given for two years: 2010 and 2015. A two-year base period of 2004 and 2005 was chosen because production was low in 2005 due to poor market conditions in the metal industry.

Phase I of the Near-Term Hybrid Passenger-Vehicle Development Program. Final report  

SciTech Connect (OSTI)

Heat engine/electric hybrid vehicles offer the potential of greatly reduced petroleum consumption, compared to conventional vehicles, without the disadvantages of limited performance and operating range associated with purely electric vehicles. This report documents a hybrid-vehicle design approach which is aimed at the development of the technology required to achieve this potential - in such a way that it is transferable to the auto industry in the near term. The development of this design approach constituted Phase I of the Near-Term Hybrid-Vehicle Program. The major tasks in this program were: (1) Mission Analysis and Performance Specification Studies; (2) Design Tradeoff Studies; and (3) Preliminary Design. Detailed reports covering each of these tasks are included as appendices to this report and issued under separate cover; a fourth task, Sensitivity Studies, is also included in the report on the Design Tradeoff Studies. Because of the detail with which these appendices cover methodology and both interim and final results, the body of this report was prepared as a brief executive summary of the program activities and results, with appropriate references to the detailed material in the appendices.

Tests show production logging problems in horizontal gas wells  

SciTech Connect (OSTI)

A study has concluded that production logging tools employed to evaluate multiphase horizontal well production behavior should be carefully screened as to their response characteristics in fully-segregated, two-phase flow. The study, performed at Marathon Oil Co.'s petroleum technology center in Littleton, Colo., indicated that gas in highly deviated well bores segregates rapidly in the presence of water, creating a downhole environment that produces sporadic responses from full bore and diverter spinners as well as density and holdup tools. Gas Research Institute (GRI), as part of its horizontal gas well completion technology program, initiated the full-scale laboratory study to determine the severity and consequences of multiphase flow on tool response from horizontal well production. The paper discusses background of the problem, the test objectives, test facility, experimental procedures, single-phase flow, two-phase flow, and recommendations.

Paraffin problems in crude oil production and transportation: A review  

SciTech Connect (OSTI)

Problems related to crystallization and deposition of paraffin waxes during production and transportation of crude oil cause losses of billions of dollars yearly to petroleum industry. The goal of this paper is to present the knowledge on such problems in a systematic and comprehensive form. The fundamental aspects of these problems are defined, and characterization of paraffins and their solubility tendencies have been discussed. It has been established conclusively that n-paraffins are predominantly responsible for this problem. Comprehensive discussion on the mechanism of crystallization of paraffins has been included. Compounds other than n-paraffins, especially asphaltenes and resins, have profound effects on solubility of n-paraffins. In evaluations of the wax potential of a crude, the climate of the area concerned should be considered. Under the most favorable conditions, n-paraffins form clearly defined orthorhombic crystals, but unfavorable conditions and the presence of impurities lead to hexagonal and/or amorphous crystallization.The gelation characteristics are also affected the same way. An attempt was made to classify the paraffin problems into those resulting from high pipeline pressure, high restarting pressure, and deposition on pipe surfaces. Fundamental aspects and mechanism of these dimensions are described. Wax deposition depends on flow rate, the temperature differential between crude and pipe surface, the cooling rate, and surface properties. Finally, methods available in the literature for predicting these problems and evaluating their mitigatory techniques are reviewed. The available methods present a very diversified picture; hence, using them to evaluate these problems becomes taxing. A top priority is standardizing these methods for the benefit of the industry. 56 refs.

Improved Oil Recovery in Fluvial Dominated Deltaic Reservoirs of Kansas - Near-Term  

SciTech Connect (OSTI)

The objective of this project is to address waterflood problems of the type found in Morrow sandstone reservoirs in southwestern Kansas and in Cherokee Group reservoirs in southeastern Kansas. Two demonstration sites operated by different independent oil operators are involved in this project. The Stewart Field is located in Finney County, Kansas and is operated by PetroSantander, Inc. Te Nelson Lease is located in Allen County, Kansas, in the N.E. Savonburg Field and is operated by James E. Russell Petroleum, Inc. General topics to be addressed are (1) reservoir management and performance evaluation, (2) waterflood optimization, and (3) the demonstration of recovery processes involving off-the-shelf technologies which can be used to enhance waterflood recovery, increase reserves, and reduce the abandonment rate of these reservoir types. In the Stewart Project, the reservoir management portion of the project conducted during Budget Period 1 involved performance evaluation. This included (1) reservoir characterization and the development of a reservoir database, (2) volumetric analysis to evaluate production performance, (3) reservoir modeling, (4) laboratory work, (5) identification of operational problems, (6) identification of unrecovered mobile oil and estimation of recovery factors, and (7) identification of the most efficient and economical recovery process. To accomplish these objectives the initial budget period was subdivided into three major tasks. The tasks were (1) geological and engineering analysis, (2) laboratory testing, and (3) unitization. Due to the presence of different operators within the field, it was necessary to unitize the field in order to demonstrate a field-wide improved recovery process. This work was completed and the project moved into Budget Period 2.

Improved oil recovery in fluvial dominated deltaic reservoirs of Kansas - Near-term, Class I  

SciTech Connect (OSTI)

This project involved two demonstration projects, one in a Marrow reservoir located in the southwestern part of the state and the second in the Cherokee Group in eastern Kansas. Morrow reservoirs of western Kansas are still actively being explored and constitute an important resource in Kansas. Cumulative oil production from the Morrow in Kansas is over 400,000,000 bbls. Much of the production from the Morrow is still in the primary stage and has not reached the mature declining state of that in the Cherokee. The Cherokee Group has produced about 1 billion bbls of oil since the first commercial production began over a century ago. It is a billion-barrel plus resource that is distributed over a large number of fields and small production units. Many of the reservoirs are operated close to the economic limit, although the small units and low production per well are offset by low costs associated with the shallow nature of the reservoirs (less than 1000 ft. deep).

LHC 2010: Summary of the Odyssey So Far and Near-Term Prospects (3/3)  

ScienceCinema (OSTI)

In 2010, the LHC delivered proton-proton collisions at an energy of 7 TeV, significantly higher than what was previously attained. This has allowed the experiments to complete the commissioning of the detectors and to perform early measurements of key standard model processes. The inclusive production of particles, jets and photons, the observation of onia and heavy-flavored meson decays, the measurement of the W and Z cross sections, and the observation of top-quark production and decay constitute a full set of measurements which form the base from which searches for physics beyond the standard model can be launched. The results from a number of searches for supersymmetry and some exotic signatures are now appearing. The lectures will review this impressive list of physics achievements from 2010 and consider briefly what 2011 may bring.

Biomass feedstock contracts: Role of land quality and yield variability in near term feasibility  

Science Journals Connector (OSTI)

Abstract In the absence of an infrastructure for the harvest, storage and purchase of cellulosic biomass, contracting is an important mechanism through which biorefineries can ensure adequate feedstock supply. We develop an optimization model to assess the economic potential of dedicated energy crops when profit-maximizing farmers allocate croplands of varying quality toward biomass in response to multi-year contracts. We evaluate the economic competitiveness of perennial grasses with traditional commodity crops, in a case study of switchgrass production in Tennessee. Assuming short-term contracts, we consider the importance of payment structure, land quality, energy crop yield and projected commodity crop returns on a farmer's decision to accept a contract for biomass production. We find that a wholesale contract, in which the farmer is guaranteed a price per unit biomass, is most effective on the highest quality of land, while a contract in which the farmer is guaranteed a price per acre is most effective on lower quality land. From the biorefinery perspective, a wholesale contract is most effective for short-term contracts while an acreage contract is most effective for long-term contracts. Breakeven pricing will only secure feedstock from farmers who produce commodity crops with unfavorable price outlooks on lower quality land; therefore, the contract price must include a premium in order to compete for space in the crop mix. The yield profile of energy crops has a significant effect on the terms at which short-term contracts will be accepted and land allocated toward feedstock production. The extent to which energy crop yields observed in field trials can be maintained at commercial scale also has a substantial effect on the scale at which farmers would be willing to participate in energy crop production.

On the Fielding of a High Gain, Shock-Ignited Target on the National Ignitiion Facility in the Near Term  

SciTech Connect (OSTI)

Shock ignition, a new concept for igniting thermonuclear fuel, offers the possibility for a near-term ({approx}3-4 years) test of high gain inertial confinement fusion on the National Ignition Facility at less than 1MJ drive energy and without the need for new laser hardware. In shock ignition, compressed fusion fuel is separately ignited by a strong spherically converging shock and, because capsule implosion velocities are significantly lower than those required for conventional hotpot ignition, fusion energy gains of {approx}60 may be achievable on NIF at laser drive energies around {approx}0.5MJ. Because of the simple all-DT target design, its in-flight robustness, the potential need for only 1D SSD beam smoothing, minimal early time LPI preheat, and use of present (indirect drive) laser hardware, this target may be easier to field on NIF than a conventional (polar) direct drive hotspot ignition target. Like fast ignition, shock ignition has the potential for high fusion yields at low drive energy, but requires only a single laser with less demanding timing and spatial focusing requirements. Of course, conventional symmetry and stability constraints still apply. In this paper we present initial target performance simulations, delineate the critical issues and describe the immediate-term R&D program that must be performed in order to test the potential of a high gain shock ignition target on NIF in the near term.

IMPROVED OIL RECOVERY IN MISSISSIPPIAN CARBONATE RESERVOIRS OF KANSAS--NEAR TERM--CLASS 2  

SciTech Connect (OSTI)

This annual report describes progress during the third year of the project entitled ''Improved Oil Recovery in Mississippian Carbonate Reservoirs in Kansas''. This project funded under the Department of Energy's Class 2 program targets improving the reservoir performance of mature oil fields located in shallow shelf carbonate reservoirs. The focus of this project is development and demonstration of cost-effective reservoir description and management technologies to extend the economic life of mature reservoirs in Kansas and the mid-continent. The project introduced a number of potentially useful technologies, and demonstrated these technologies in actual oil field operations. Advanced technology was tailored specifically to the scale appropriate to the operations of Kansas producers. An extensive technology transfer effort is ongoing. Traditional technology transfer methods (e.g., publications and workshops) are supplemented with a public domain relational database and an online package of project results that is available through the Internet. The goal is to provide the independent complete access to project data, project results and project technology on their desktop. Included in this report is a summary of significant project results at the demonstration site (Schaben Field, Ness County, Kansas). The value of cost-effective techniques for reservoir characterization and simulation at Schaben Field were demonstrated to independent operators. All major operators at Schaben have used results of the reservoir management strategy to locate and drill additional infill locations. At the Schaben Demonstration Site, the additional locations resulted in incremental production increases of 200 BOPD from a smaller number of wells.

IMPROVED OIL RECOVERY IN MISSISSIPPIAN CARBONATE RESERVOIRS OF KANSAS - NEAR TERM - CLASS 2  

SciTech Connect (OSTI)

This annual report describes progress during the final year of the project entitled ''Improved Oil Recovery in Mississippian Carbonate Reservoirs in Kansas''. This project funded under the Department of Energy's Class 2 program targets improving the reservoir performance of mature oil fields located in shallow shelf carbonate reservoirs. The focus of the project was development and demonstration of cost-effective reservoir description and management technologies to extend the economic life of mature reservoirs in Kansas and the mid-continent. As part of the project, tools and techniques for reservoir description and management were developed, modified and demonstrated, including PfEFFER spreadsheet log analysis software. The world-wide-web was used to provide rapid and flexible dissemination of the project results through the Internet. A summary of demonstration phase at the Schaben and Ness City North sites demonstrates the effectiveness of the proposed reservoir management strategies and technologies. At the Schaben Field, a total of 22 additional locations were evaluated based on the reservoir characterization and simulation studies and resulted in a significant incremental production increase. At Ness City North Field, a horizontal infill well (Mull Ummel No.4H) was planned and drilled based on the results of reservoir characterization and simulation studies to optimize the location and length. The well produced excellent and predicted oil rates for the first two months. Unexpected presence of vertical shale intervals in the lateral resulted in loss of the hole. While the horizontal well was not economically successful, the technology was demonstrated to have potential to recover significant additional reserves in Kansas and the Midcontinent. Several low-cost approaches were developed to evaluate candidate reservoirs for potential horizontal well applications at the field scale, lease level, and well level, and enable the small independent producer to identify efficiently candidate reservoirs and also to predict the performance of horizontal well applications.

SOLVING THE SHUGART QUEEN SAND PENASCO UNIT DECLINING PRODUCTION PROBLEM  

SciTech Connect (OSTI)

The Penasco Shugart Queen Sand Unit located in sections 8, 9, 16 & 17, T18S, 31E Eddy County New Mexico is operated by MNA Enterprises Ltd. Co. Hobbs, NM. The first well in the Unit was drilled in 1939 and since that time the Unit produced 535,000 bbl of oil on primary recovery and 375,000 bbl of oil during secondary recovery operations that commenced in 1973. The Unit secondary to primary ratio is 0.7, but other Queen waterfloods in the area had considerably larger S/P ratios. On June 25 1999 MNA was awarded a grant under the Department of Energy's ''Technology Development with Independents'' program. The grant was used to fund a reservoir study to determine if additional waterflood reserves could be developed. A total of 14 well bores that penetrate the Queen at 3150 ft are within the Unit boundaries. Eleven of these wells produced oil during the past 60 years. Production records were pieced together from various sources including the very early state production records. One very early well had a resistivity log, but nine of the wells had no logs, and four wells had gamma ray-neutron count-rate perforating logs. Fortunately, recent offset deep drilling in the area provided a source of modern logs through the Queen. The logs from these wells were used to analyze the four old gamma ray-neutron logs within the Unit. Additionally the offset well log database was sufficient to construct maps through the unit based on geostatistical interpolation methods. The maps were used to define the input parameters required to simulate the primary and secondary producing history. The history-matched simulator was then used to evaluate four production scenarios. The best scenario produces 51,000 bbl of additional oil over a 10-year period. If the injection rate is held to 300 BWPD the oil rate declines to a constant 15 BOPD after the first year. The projections are reasonable when viewed in the context of the historical performance ({approx}30 BOPD with a {approx}600 BWPD injection rate during 1980-1990). If an additional source of water is developed, increasing the injection rate to 600 BWPD will double the oil-producing rate. During the log evaluation work the presence of a possibly productive Penrose reservoir about 200 ft below the Queen was investigated. The Penrose zone exists throughout the Unit, but appears to be less permeable than the Queen. The maps suggest that either well 16D or 16C are suitable candidates for testing the Penrose zone.

Problem solving in product development: a model for the advanced materials industries  

Science Journals Connector (OSTI)

Problem solving has been identified as a key aspect of product development. Yet, existing descriptive models of problem solving in product development are derived from experience in traditional fabrication and assembly-based industries. This paper examines the sequence of problem solving activities in the advanced materials industries. As opposed to the paradigm of product development seen in industries based on traditional metal fabrication and assembly production technology, development activities in advanced materials industries are focused around a core effort in process development. The paper characterises the steps of design and the associated testing patterns in the advanced materials industries. The model formalises the emphasis on process design and process experimentation, providing a richer description of the problem-solving sequence than the traditional design-build-test sequence so common in the fabrication/assembly industries.

Abstract This paper treats the product location problem in warehouses, i.e., stock keeping units (SKUs) are to be assigned to storage positions in order to minimize the resulting picking effort when retrieving \\{SKUs\\} in a pick-by-order environment. We restrict our view on warehouses having a single cross aisle and show that already very simple layouts consisting of only a single rack lead to NP-hard optimization problems. In addition to a complexity analysis for different layouts, elementary solution procedures are introduced and tested. Finally, we investigate the robustness of our deterministic problem when facing erroneous input data.

Improved oil recovery in fluvial dominated deltaic reservoirs of Kansas -- Near term. Quarterly report, June 30--September 30, 1995  

SciTech Connect (OSTI)

The objective of this project is to address waterflood problems of the type found in Cherokee Group reservoirs in southeastern Kansas and in Morrow sandstone reservoirs in southwestern Kansas. Two demonstration sites operated by different independent oil operators are involved in the project. General topics to be addressed will be (1) reservoir management and performance evaluation; (2) waterflood optimization, and (3) the demonstration of recovery processes involving off-the-shelf technologies which can be used to enhance waterflood recovery, increase reserves, and reduce the abandonment rate of these reservoir types. The reservoir management portion of the project will involve performance evaluation and will include such work as (1) reservoir characterization and the development of a reservoir database, (2) identification of operational problems, (3) identification of near wellbore problems, (4) identification of unrecovered mobile oil and estimation of recovery factors, and (5) identification of the most efficient and economical recovery process. The waterflood optimization portion of the project involves only the Nelson Lease. It will be based on the performance evaluation and will involve (1) design and implementation of a water cleanup system for the waterflood, (2) application of well remedial work such as polymer gel treatments to improve vertical sweep efficiency, and (3) changes in waterflood patterns to increase sweep efficiency. Finally, it is planned to implement an improved recovery process on both field demonstration sites.

Brain microstructural development at near-term age in very-low-birth-weight preterm infants: An atlas-based diffusion imaging study  

Science Journals Connector (OSTI)

Abstract At near-term age the brain undergoes rapid growth and development. Abnormalities identified during this period have been recognized as potential predictors of neurodevelopment in children born preterm. This study used diffusion tensor imaging (DTI) to examine white matter (WM) microstructure in very-low-birth-weight (VLBW) preterm infants to better understand regional WM developmental trajectories at near-term age. DTI scans were analyzed in a cross-sectional sample of 45 VLBW preterm infants (BW ? 1500 g, GA ? 32 weeks) within a cohort of 102 neonates admitted to the NICU and recruited to participate prior to standard-of-care MRI, from 2010 to 2011, 66/102 also had DTI. For inclusion in this analysis, 45 infants had DTI, no evidence of brain abnormality on MRI, and were scanned at PMA ? 40 weeks (34.7–38.6). White matter microstructure was analyzed in 19 subcortical regions defined by DiffeoMap neonatal brain atlas, using threshold values of trace  0.15. Regional fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) were calculated and temporal–spatial trajectories of development were examined in relation to PMA and brain region location. Posterior regions within the corona radiata (CR), corpus callosum (CC), and internal capsule (IC) demonstrated significantly higher mean FA values compared to anterior regions. Posterior regions of the CR and IC demonstrated significantly lower RD values compared to anterior regions. Centrally located projection fibers demonstrated higher mean FA and lower RD values than peripheral regions including the posterior limb of the internal capsule (PLIC), cerebral peduncle, retrolenticular part of the IC, posterior thalamic radiation, and sagittal stratum. Centrally located association fibers of the external capsule had higher FA and lower RD than the more peripherally-located superior longitudinal fasciculus (SLF). A significant relationship between PMA-at-scan and FA, MD, and RD was demonstrated by a majority of regions, the strongest correlations were observed in the anterior limb of the internal capsule, a region undergoing early stages of myelination at near-term age, in which FA increased (r = .433, p = .003) and MD (r = ? .545, p = .000) and RD (r = ? .540, p = .000) decreased with PMA-at-scan. No correlation with PMA-at-scan was observed in the CC or SLF, regions that myelinate later in infancy. Regional patterns of higher FA and lower RD were observed at this near-term age, suggestive of more advanced microstructural development in posterior compared to anterior regions within the CR, CC, and IC and in central compared to peripheral WM structures. Evidence of region-specific rates of microstructural development was observed. Temporal–spatial patterns of WM microstructure development at near-term age have important implications for interpretation of near-term DTI and for identification of aberrations in typical developmental trajectories that may signal future impairment.

Water: May be the Best Near-Term Benefit and Driver of a Robust Wind Energy Future (Poster)  

SciTech Connect (OSTI)

Water may be the most critical natural resource variable that affects the selection of generation options in the next decade. Extended drought in the western United States and more recently in the Southeast has moved water management and policy to the forefront of the energy options discussions. Recent climate change studies indicate that rising ambient temperatures could increase evapotranspiration by more than 25% to 30% in large regions of the country. Increasing demand for electricity, and especially from homegrown sources, inevitably will increase our thermal fleet, which consumes 400 to 700 gal/MWh for cooling. Recovering the vast oil shale resources in the West (one of the energy options discussed) is water intensive and threatens scarce water supplies. Irrigation for the growing corn ethanol industry requires 1,000 to 2,000 gallons of water for 1 gallon of production. Municipalities continue to grow and drive water demands and emerging constrained market prices upward. As illustrated by the 20% Wind Energy by 2030 analysis, wind offers an important mitigation opportunity: a 4-trillion-gallon water savings. This poster highlights the emerging constrained water situation in the United States and presents the case for wind energy as one of the very few means to ameliorate the emerging water wars in various U.S. regions.

Improved oil recovery in fluvial dominated deltaic reservoirs of Kansas - near - term. Technical progress report, June 17, 1994--June 17, 1995  

SciTech Connect (OSTI)

Common oil field problems exist in fluvial dominated deltaic reservoirs in Kansas. The problems are poor waterflood sweep and lack of reservoir management. The poor waterflood sweep efficiency is due to (1) reservoir heterogeneity, (2) channeling of injected water through high permeability zones or fractures, and (3) clogging of water injection wells with solids as a result of poor water quality. In many instances the lack of reservoir management is due to lack of (1) data collection and organization, (2) integrated analysis of existing data by geological and engineering personnel, and (3) identification of optimum recovery techniques. Two demonstration sites operated by different independent oil operators are involved in the project. The Stewart Field (on the latter stage of primary production) is located in Finney County, Kansas, and was operated by Sharon Resources, Inc. and is now operated by North American Resources Company. The Nelson Lease (an existing waterflood) is located in Allen County, Kansas, in the N.E. Savonburg Field and is operated by James E. Russell Petroleum, Inc. The objective is to increase recovery efficiency and economics in these type of reservoirs. The technologies being applied to increase waterflood sweep efficiency are (1) in situ permeability modification treatments, (2) infill drilling, (3) pattern changes, and (4) air flotation to improve water quality. The technologies being applied to improve reservoir management are (1) database development, (2) reservoir simulation, (3) transient testing, (4) database management, and (5) integrated geological and engineering analysis.

Capital investment requirements for greenhouse gas emissions mitigation in power generation on near term to century time scales and global to regional spatial scales  

Science Journals Connector (OSTI)

Abstract Our paper explores the implication of climate mitigation policy and electricity generation technology performance for capital investment demands by the electric power sector on near term to century time scales. We find that stabilizing GHG emissions will require additional investment in the electricity generation sector over and above investments that would be needed in the absence of climate policy, in the range of 15 to 29 trillion US$ (48–94%) depending on the stringency of climate policy during the period 2015 to 2095 under default technology assumptions. This increase reflects the higher capital intensity of power systems that control emissions as well as increased electrification of the global economy. Limits on the penetration of nuclear and carbon capture and storage technology could increase costs substantially. Energy efficiency improvements can reduce the investment requirement by 18 to 24 trillion US$ (compared to default technology climate policy assumptions), depending on climate policy scenario. We also highlight the implications of different technology evolution scenarios for different regions. Under default technology set, the heaviest investments across scenarios in power generation were observed in China, India, SE Asia and Africa regions with the latter three regions dominating in the second half of the 21st century.

The peak of oil production—Timings and market recognition  

Science Journals Connector (OSTI)

Energy is essential for present societies. In particular, transportation systems depend on petroleum-based fuels. That world oil production is set to pass a peak is now a reasonably accepted concept, although its date is far from consensual. In this work, we analyze the true expectations of the oil market participants about the future availability of this fundamental energy source. We study the evolution through time of the curves of crude oil futures prices, and we conclude that the market participants, among them the crude oil producers, already expect a near-term peak of oil production. This agrees with many technical predictions for the date of peak production, including our own, that point to peak dates around the end of the present decade. If this scenario is confirmed, it can cause serious social and economical problems because societies will have little time to perform the necessary adjustments.

Identifying and Remediating High Water Production Problems in Basin-Centered Formations  

SciTech Connect (OSTI)

Through geochemical analyses of produced waters, petrophysics, and reservoir simulation we developed concepts and approaches for mitigating unwanted water production in tight gas reservoirs and for increasing recovery of gas resources presently considered noncommercial. Only new completion research (outside the scope of this study) will validate our hypothesis. The first task was assembling and interpreting a robust regional database of historical produced-water analyses to address the production of excessive water in basin-centered tight gas fields in the Greater Green (GGRB ) and Wind River basins (WRB), Wyoming. The database is supplemented with a sampling program in currently active areas. Interpretation of the regional water chemistry data indicates most produced waters reflect their original depositional environments and helps identify local anomalies related to basement faulting. After the assembly and evaluation phases of this project, we generated a working model of tight formation reservoir development, based on the regional nature and occurrence of the formation waters. Through an integrative approach to numerous existing reservoir concepts, we synthesized a generalized development scheme organized around reservoir confining stress cycles. This single overarching scheme accommodates a spectrum of outcomes from the GGRB and Wind River basins. Burial and tectonic processes destroy much of the depositional intergranular fabric of the reservoir, generate gas, and create a rock volume marked by extremely low permeabilities to gas and fluids. Stress release associated with uplift regenerates reservoir permeability through the development of a penetrative grain bounding natural fracture fabric. Reservoir mineral composition, magnitude of the stress cycle and local tectonics govern the degree, scale and exact mechanism of permeability development. We applied the reservoir working model to an area of perceived anomalous water production. Detailed water analyses, seismic mapping, petrophysics, and reservoir simulation indicate a lithologic and structural component to excessive in situ water permeability. Higher formation water salinity was found to be a good pay indicator. Thus spontaneous potential (SP) and resistivity ratio approaches combined with accurate formation water resistivity (Rw) information may be underutilized tools. Reservoir simulation indicates significant infill potential in the demonstration area. Macro natural fracture permeability was determined to be a key element affecting both gas and water production. Using the reservoir characterization results, we generated strategies for avoidance and mitigation of unwanted water production in the field. These strategies include (1) more selective perforation by improved pay determination, (2) using seismic attributes to avoid small-scale fault zones, and (3) utilizing detailed subsurface information to deliberately target optimally located small scale fault zones high in the reservoir gas column. Tapping into the existing natural fracture network represents opportunity for generating dynamic value. Recognizing the crucial role of stress release in the natural generation of permeability within tight reservoirs raises the possibility of manmade generation of permeability through local confining stress release. To the extent that relative permeabilities prevent gas and water movement in the deep subsurface a reduction in stress around a wellbore has the potential to increase the relative permeability conditions, allowing gas to flow. For this reason, future research into cavitation completion methods for deep geopressured reservoirs is recommended.

The discrete forward–reserve problem – Allocating space, selecting products, and area sizing in forward order picking  

Science Journals Connector (OSTI)

Abstract To reduce labor-intensive and costly order picking activities, many distribution centers are subdivided into a forward area and a reserve (or bulk) area. The former is a small area where most popular stock keeping units (SKUs) can conveniently be picked, and the latter is applied for replenishing the forward area and storing \\{SKUs\\} that are not assigned to the forward area at all. Clearly, reducing \\{SKUs\\} stored in forward area enables a more compact forward area (with reduced picking effort) but requires a more frequent replenishment. To tackle this basic trade-off, different versions of forward–reserve problems determine the \\{SKUs\\} to be stored in forward area, the space allocated to each SKU, and the overall size of the forward area. As previous research mainly focuses on simplified problem versions (denoted as fluid models), where the forward area can continuously be subdivided, we investigate discrete forward–reserve problems. Important subproblems are defined and computation complexity is investigated. Furthermore, we experimentally analyze the model gaps between the different fluid models and their discrete counterparts.

Production of Hydrogen from Peanut Shells  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Production of Hydrogen from Peanut Shells Production of Hydrogen from Peanut Shells The goal of this project is the production of renewable hydrogen from agricultural residues, in the near-term time frame (~three years) and at a comparable cost to existing methane reforming technologies. The hydrogen produced will be blended with CNG and used to power a bus in Albany, GA. Our strategy is to produce hydrogen from biomass pyrolysis oils in conjunction with high value co-products. Activated carbon can be made from agricultural residues in a two- stage process: (1) slow pyrolysis of biomass to produce charcoal, and (2) high temperature processing to form activated carbon. The vapor by-products from the first step can be steam reformed into hydrogen. NREL has developed the technology for bio-

Microbial production of energy: gaseous fuels  

SciTech Connect (OSTI)

Although several gaseous fuels could be derived by microbial fermentation, in the near term it will be economical to produce biomethane by anaerobic digestion of readily available heterogeneous feeds that may be obtained free or at low cost. Various wastes and biomass species grown in polluted waters are attractive feeds for commercial methane production. Biomethane could meet significant portions of the energy requirements of a number of countries. The conventional digestion-process configurations used for sewage sludge digestion were developed to ensure fail-safe maximized sludge stabilization, and are not necessarily suitable for maximized energy production. Commercial biomethane energy plants must be designed to optimize the net methane income production rate. Separate process designs are needed to effect optimized conversion of soluble, semisolid and solid feeds. Several approaches to improved process designs may be considered. The approaches include development of innovative fermentation modes, application of novel reactor designs, development of cost-effective pre/post-treatment techniques for feeds and unconverted residues, use of biostimulants, and development of new microbial strains. The last two approaches may not be feasible in the near future. In the near term, the objective of economical biomethane production at short HRT's and high loadings may be realized by applying new fermentation modes, such as two-phase digestion, and by utilizing new reactor designs, such as upflow digesters, the packed-bed reactors, plug-flow digesters, biodisc reactors, and others. The two-phase process has exhibited the highest reported methane yields from several soluble and particulate feeds and holos considerable commercialization potential. A number of new biomethanation processes have been proven feasible within the last decade by pilot- and commercial-scale application. 95 references, 14 figures, 12 tables.

Spreadsheet modelling for solving combinatorial problems: The vendor selection problem  

E-Print Network [OSTI]

Spreadsheets have grown up and became very powerful and easy to use tools in applying analytical techniques for solving business problems. Operations managers, production managers, planners and schedulers can work with them in developing solid and practical Do-It-Yourself Decision Support Systems. Small and Medium size organizations, can apply OR methodologies without the presence of specialized software and trained personnel, which in many cases cannot afford anyway. This paper examines an efficient approach in solving combinatorial programming problems with the use of spreadsheets. A practical application, which demonstrates the approach, concerns the development of a spreadsheet-based DSS for the Multi Item Procurement Problem with Fixed Vendor Cost. The DSS has been build using exclusively standard spreadsheet feature and can solve real problems of substantial size. The benefits and limitations of the approach are also discussed.

Pu Glass Fabrication and Product Consistency Testing  

SciTech Connect (OSTI)

The DOE/EM plans to conduct the Plutonium Vitrification Project at the Savannah River Site (SRS). An important part of this project is to reduce the attractiveness of the plutonium by fabricating a plutonium glass form and immobilizing the Pu form within the high level waste (HLW) glass prepared in the Defense Waste Processing Facility (DWPF). This requires that a project schedule that is consistent with EM plans for DWPF and cleanup of the SRS be developed. Critical inputs to key decisions in the vitrification project schedule are near-term data that will increase confidence that lanthanide borosilicate (LaBS) glass product is suitable for disposal in the Yucca Mountain Repository. A workshop was held on April 28, 2005 at Bechtel SAIC Company facility in Las Vegas, NV to define the near term data needs. Dissolution rate data and the fate of plutonium oxide and the neutron absorbers during the dissolution process were defined as key data needs. A suite of short-term tests were defined at the workshop to obtain the needed data. The objectives of these short-term tests are to obtain data that can be used to show that the dissolution rate of a LaBS glass is acceptable and to show that the extent of Pu separation from neutron absorbers, as the glass degrades and dissolves, is not likely to lead to criticality concerns. An additional data need was identified regarding the degree of macroscopic cracking that occurs during processing of the Pu glass waste form and subsequent pouring of HLW glass in the DWPF. A final need to evaluate new frit formulations that may increase the durability of the plutonium glass and/or decrease the degree to which neutron absorbers separate from the plutonium during dissolution was identified. This task plan covers testing to support a near term data need regarding glass dissolution performance. Separate task plans will be developed for testing to address the degree of macroscopic cracking and the development of alternative frit formulations. The Product Consistency Test (PCT) was identified as a means to provide some of the near term performance data. The PCT is a static test method in which known masses of crushed glass and demineralized water are reacted for a desired duration [1]. There are two reasons to perform the PCT. The first is that the results are used as a measure of acceptance in the Waste Acceptance Product Specifications Document (WAPS) [2]. The second is the need for long-term static test results that can be used to verify the applicability of the degradation model. Thus, the primary focus will be on the use of the PCT Method B (PCT-B) to study the formation and stability of colloids and to study alteration phases formed on the glass surface. The standard 7-day PCT in demineralized water (PCT-A) will be included to demonstrate compliance with the waste acceptance criterion and determine the value of the k{sub E} rate parameter for comparison with the Defense HLW Glass Degradation Model [3].

Economics of large-scale thorium oxide production: assessment of domestic resources  

SciTech Connect (OSTI)

The supply curve illustrates that sufficient amounts of thorium exist supply a domestic thorium-reactor economy. Most likely costs of production range from $3 to $60/lb ThO/sub 2/. Near-term thorium oxide resources include the stockpiles in Ohio, Maryland, and Tennessee and the thorite deposits at Hall Mountain, Idaho. Costs are under $10/lb thorium oxide. Longer term economic deposits include Wet Mountain, Colorado; Lemhi Pass, Idaho; and Palmer, Michigan. Most likely costs are under $20/lb thorium oxide. Long-term deposits include Bald Mountain, Wyoming; Bear Lodge, Wyoming; and Conway, New Hampshire. Costs approximately equal or exceed $50/lb thorium oxide.

Solving the platform selection problem using an evolutionary algorithm  

Science Journals Connector (OSTI)

Contemporary manufacturing is characterised by fierce competition on price, quality and features offered. Successful manufacturers avoid developing products individually and base their products on a platform, using it as the starting point and then adding or removing components to create the desired variety. In this paper, we select the optimal platform for the production of a product family while minimising the overall production cost. The problem is formulated as an optimisation problem, minimising the production cost. Both an optimal formulation and an evolutionary strategy based on genetic algorithm are presented. The approach is illustrated with an industrial example.

The Inverse Ising Problem  

Science Journals Connector (OSTI)

Abstract The inverse Ising problem consists of taking a set of Ising configurations generated with unknown interaction parameters, and deter- mining reliable estimates for the values of those interaction parameters. The problem first arose in connection with the Monte Carlo renormalization group, and was solved thirty years ago. Recently, there has been renewed interest in the inverse Ising problem due to biological applications. The original solution seems to have been forgotten, as it was rediscovered in a different representation by Aurell and Ekeberg in 2012. In this paper we modify the earlier equations to solve problems that are not translationally invariant.

Problems in squeeze cementing  

SciTech Connect (OSTI)

For the past half century, work has been carried out to improve squeeze cementing. During the course of time, new techniques, equipment, cement and cement additives were introduced. Work is still underway to improve squeeze cementing. Basic concept of squeeze cementing, understanding the problems, planning for a squeeze job and then later testing of the job help in achieving the goal. Solutions were offered to some common problems, whereas many regional problems need time to time study and effort. Squeezing long perforations in highly permeable sand has always been a problem, for which some techniques were presented.

High efficiency direct fuel cell hybrid power cycle for near term application  

SciTech Connect (OSTI)

Direct carbonate fuel cells being developed by Energy Research Corporation can generate power at an efficiency approaching 60% LHV. This unique fuel cell technology can consume natural gas and other hydrocarbon based fuels directly without requiring an external reformer, thus providing a simpler and inherently efficient power generation system. A 2 MW power plant demonstration of this technology has been initiated at an installation in the city of Santa Clara in California. A 2.85 MW commercial configuration shown in Figure 1 is presently being developed. The complete plant includes the carbonate fuel cell modules, an inverter, transformer and switchgear, a heat recovery unit and supporting instrument air and water treatment systems. The emission levels for this 2.85 MW plant are projected to be orders of magnitude below existing or proposed standards. The 30 year levelized cost of electricity, without inflation, is projected to be approximately 5{cents}/kW-h assuming capital cost for the carbonate fuel cell system of $1000/kW.

Radioisotope electric propulsion (REP): A near-term approach to nuclear propulsion  

Science Journals Connector (OSTI)

Studies over the last decade have shown radioisotope-based nuclear electric propulsion to be enhancing and, in some cases, enabling for many potential robotic science missions. Also known as radioisotope electric propulsion (REP), the technology offers the performance advantages of traditional reactor-powered electric propulsion (i.e., high specific impulse propulsion at large distances from the Sun), but with much smaller, affordable spacecraft. Future use of REP requires development of radioisotope power sources with system specific powers well above that of current systems. The US Department of Energy and NASA have developed an advanced Stirling radioisotope generator (ASRG) engineering unit, which was subjected to rigorous flight qualification-level tests in 2008, and began extended lifetime testing later that year. This advancement, along with recent work on small ion thrusters and life extension technology for Hall thrusters, could enable missions using REP sometime during the next decade.

Advanced Amine Solvent Formulations and Process Integration for Near-Term CO2 Capture Success  

SciTech Connect (OSTI)

This Phase I SBIR project investigated the economic and technical feasibility of advanced amine scrubbing systems for post-combustion CO2 capture at coal-fired power plants. Numerous combinations of advanced solvent formulations and process configurations were screened for energy requirements, and three cases were selected for detailed analysis: a monoethanolamine (MEA) base case and two “advanced” cases: an MEA/Piperazine (PZ) case, and a methyldiethanolamine (MDEA) / PZ case. The MEA/PZ and MDEA/PZ cases employed an advanced “double matrix” stripper configuration. The basis for calculations was a model plant with a gross capacity of 500 MWe. Results indicated that CO2 capture increased the base cost of electricity from 5 cents/kWh to 10.7 c/kWh for the MEA base case, 10.1 c/kWh for the MEA / PZ double matrix, and 9.7 c/kWh for the MDEA / PZ double matrix. The corresponding cost per metric tonne CO2 avoided was 67.20 $/tonne CO2, 60.19 $/tonne CO2, and 55.05 $/tonne CO2, respectively. Derated capacities, including base plant auxiliary load of 29 MWe, were 339 MWe for the base case, 356 MWe for the MEA/PZ double matrix, and 378 MWe for the MDEA / PZ double matrix. When compared to the base case, systems employing advanced solvent formulations and process configurations were estimated to reduce reboiler steam requirements by 20 to 44%, to reduce derating due to CO2 capture by 13 to 30%, and to reduce the cost of CO2 avoided by 10 to 18%. These results demonstrate the potential for significant improvements in the overall economics of CO2 capture via advanced solvent formulations and process configurations.

E-Print Network [OSTI]

A thermodynamic analogue of the Pauli problem (reconstruction of a wavefunction from the position and momentum distributions) is formulated. The coordinates of a quantum system are replaced by the inverse absolute temperature and other intensive quantities, and the Planck constant is replaced by the Boltzmann constant multiplied by two. A new natural mathematical generalization of the quasithermodynamic fluctuation theory is suggested and sufficient conditions for the existence of asymptotic solutions of the thermodynamic Pauli problem are obtained.

Gulf Coast Distillate Production  

Gasoline and Diesel Fuel Update (EIA)

4 of 15 4 of 15 Notes: PADD 3 is a major source of supply for the East Coast. This graph shows how during the winter of 1997-1998 when distillate stocks were very high, production fell back. In contrast, we entered the winter of 1996-1997 with very low stocks, and refineries reached record production levels as they tried to build stocks late in the season. Notice that production is normally reduced in January as distillate stocks are used to meet demand and as refineries begin maintenance and turnovers, which continue into February. This January is no different. There is room for some production increases in January and February, if refineries postpone maintenance. But postponing maintenance and turnarounds can create problems when the gasoline production season begins in March and April.

The chemical composition of the Sun is among the most important quantities in astrophysics. Solar abundances are needed for modelling stellar atmospheres, stellar structure and evolution, population synthesis, and galaxies as a whole. The solar abundance problem refers to the conflict of observed data from helioseismology and the predictions made by stellar interior models for the Sun, if these models use the newest solar chemical composition obtained with 3D and NLTE models of radiative transfer. Here we take a close look at the problem from observational and theoretical perspective. We also provide a list of possible solutions, which have yet to be tested.

A Quantum Production Model  

E-Print Network [OSTI]

The production system is a theoretical model of computation relevant to the artificial intelligence field allowing for problem solving procedures such as hierarchical tree search. In this work we explore some of the connections between artificial intelligence and quantum computation by presenting a model for a quantum production system. Our approach focuses on initially developing a model for a reversible production system which is a simple mapping of Bennett's reversible Turing machine. We then expand on this result in order to accommodate for the requirements of quantum computation. We present the details of how our proposition can be used alongside Grover's algorithm in order to yield a speedup comparatively to its classical counterpart. We discuss the requirements associated with such a speedup and how it compares against a similar quantum hierarchical search approach.

Both approaches divide the problem into two or more subproblems, together with linear constraints that enforce agreement between solutions to the different problems through a series of iterations.

2 - Production, properties and environmental impact of hydrocarbon fuel conversion  

Science Journals Connector (OSTI)

Abstract: Hydrocarbon fuels are an essential part of modern life and commerce and will remain so for the next 50 years. Carbon dioxide emissions from fossil fuels damage our environment, causing global climate changes. For 150 years, fossil fuels have caused atmospheric carbon dioxide levels to increase by amounts that are debatable, arguable and, at best, guestimates. A transition to cleaner, more secure energy is necessary to slow down global warming. Renewable energy is growing fast, but still far from replacing carbon-intensive energy sources. Even if oil production declines soon, fossil fuels will dominate the world’s energy mix for years. In the near term, improving the use of oil, natural gas and coal will be key. Oil will remain the world’s top energy source for decades, but decline in production could send prices soaring. A dream come true for climate activists – the eventual end of the Petroleum Age – could be a time wrought with tension for the industrialized world.

Large Spectral Library Problem  

SciTech Connect (OSTI)

Hyperspectral imaging produces a spectrum or vector at each image pixel. These spectra can be used to identify materials present in the image. In some cases, spectral libraries representing atmospheric chemicals or ground materials are available. The challenge is to determine if any of the library chemicals or materials exist in the hyperspectral image. The number of spectra in these libraries can be very large, far exceeding the number of spectral channels collected in the ¯eld. Suppose an image pixel contains a mixture of p spectra from the library. Is it possible to uniquely identify these p spectra? We address this question in this paper and refer to it as the Large Spectral Library (LSL) problem. We show how to determine if unique identi¯cation is possible for any given library. We also show that if p is small compared to the number of spectral channels, it is very likely that unique identi¯cation is possible. We show that unique identi¯cation becomes less likely as p increases.

About an Optimal Visiting Problem  

SciTech Connect (OSTI)

In this paper we are concerned with the optimal control problem consisting in minimizing the time for reaching (visiting) a fixed number of target sets, in particular more than one target. Such a problem is of course reminiscent of the famous 'Traveling Salesman Problem' and brings all its computational difficulties. Our aim is to apply the dynamic programming technique in order to characterize the value function of the problem as the unique viscosity solution of a suitable Hamilton-Jacobi equation. We introduce some 'external' variables, one per target, which keep in memory whether the corresponding target is already visited or not, and we transform the visiting problem in a suitable Mayer problem. This fact allows us to overcome the lacking of the Dynamic Programming Principle for the originary problem. The external variables evolve with a hysteresis law and the Hamilton-Jacobi equation turns out to be discontinuous.

Preferred hierarchy scales from the product landscape  

E-Print Network [OSTI]

The product landscape method has been recently proposed to solve hierarchy problems such as the cosmological constant problem. We suggest that the parameter distribution on logarithmic scales should be used as a benchmark for hierarchy, and the preferred hierarchy scales can be obtained from the distribution peak. It is shown that generating hierarchy from purely product distribution is very inefficient. To achieve a reasonably acceptable efficiency, other effects such as accumulation of weak hierarchy in the effective theory should be incorporated.

Generalized quantum state discrimination problems  

E-Print Network [OSTI]

We address a broad class of optimization problems of finding quantum measurements, which includes the problems of finding an optimal measurement in the Bayes criterion and a measurement maximizing the average success probability with a fixed rate of inconclusive results. Our approach can deal with any problem in which each of the objective and constraint functions is formulated by the sum of the traces of the multiplication of a Hermitian operator and a detection operator. We first derive dual problems and necessary and sufficient conditions for an optimal measurement. We also consider the minimax version of these problems and provide necessary and sufficient conditions for a minimax solution. Finally, for optimization problem having a certain symmetry, there exists an optimal solution with the same symmetry. Examples are shown to illustrate how our results can be used.

Modular Hybrid Plasma Reactor for Low Cost Bulk Production of Nanomaterials  

SciTech Connect (OSTI)

INL developed a bench scale modular hybrid plasma system for gas phase nanomaterials synthesis. The system was being optimized for WO3 nanoparticles production and scale model projection to a 300 kW pilot system. During the course of technology development many modifications had been done to the system to resolve technical issues that had surfaced and also to improve the performance. All project tasks had been completed except 2 optimization subtasks. These 2 subtasks, a 4-hour and an 8-hour continuous powder production runs at 1 lb/hr powder feeding rate, were unable to complete due to technical issues developed with the reactor system. The 4-hour run had been attempted twice and both times the run was terminated prematurely. The modular electrode for the plasma system was significantly redesigned to address the technical issues. Fabrication of the redesigned modular electrodes and additional components had been completed at the end of the project life. However, not enough resource was available to perform tests to evaluate the performance of the new modifications. More development work would be needed to resolve these problems prior to scaling. The technology demonstrated a surprising capability of synthesizing a single phase of meta-stable delta-Al2O3 from pure alpha-phase large Al2O3 powder. The formation of delta-Al2O3 was surprising because this phase is meta-stable and only formed between 973-1073 K, and delta-Al2O3 is very difficult to synthesize as a single phase. Besides the specific temperature window to form this phase, this meta-stable phase may have been stabilized by nanoparticle size formed in a high temperature plasma process. This technology may possess the capability to produce unusual meta-stable nanophase materials that would be otherwise difficult to produce by conventional methods. A 300 kW INL modular hybrid plasma pilot scale model reactor had been projected using the experimental data from PPG Industries 300 kW hot wall plasma reactor. The projected size of the INL 300 kW pilot model reactor would be about 15% that of the PPG 300 kW hot wall plasma reactor. Including the safety net factor the projected INL pilot reactor size would be 25-30% of the PPG 300 kW hot wall plasma pilot reactor. Due to the modularity of the INL plasma reactor and the energy cascading effect from the upstream plasma to the downstream plasma the energy utilization is more efficient in material processing. It is envisioning that the material through put range for the INL pilot reactor would be comparable to the PPG 300 kW pilot reactor but the energy consumption would be lower. The INL hybrid plasma technology is rather close to being optimized for scaling to a pilot system. More near term development work is still needed to complete the process optimization before pilot scaling.

Western Regional Final Supplemental Environmental Impact Statement: Rulemaking for Small Power Production and Cogeneration Facilities - Exemptions for Geothermal Facilities  

SciTech Connect (OSTI)

Section 643 of the Energy Security Act of 1980 directed the Federal Energy Regulatory Commission to develop rules to further encourage geothermal development by Small Power Production Facilities. This rule amends rules previously established in Dockets No. RM79-54 and 55 under Section 201 and 210 of the Public Utility Regulatory Policies Act of 1978 (PURPA). The analysis shows that the rules are expected to stimulate the development of up to 1,200 MW of capacity for electrical generation from geothermal facilities by 1995--1,110 MW more than predicted in the original PURPA EIS. This Final Supplemental EIS to the DEIS, issued by FERC in June 1980, forecasts likely near term development and analyzes environmental effects anticipated to occur due to development of geothermal resources in the Western United States as a result of this additional rulemaking.

Coalbed methane: A partial solution to Indonesia`s growing energy problems  

SciTech Connect (OSTI)

Indonesia contains the largest resources of coal in Southeast Asia. Indonesian scientists estimate that the in-place coalbed methane resource in 16 onshore basins is about 213 Tcf ({approximately}6 Tcm). This volume is approximately double Indonesia`s current reserves of natural gas. Indonesia is a rapidly industrializing nation of 186 million people, of which 111 million live in Java and 38 million in Sumatra. As industrialization progresses from the present low level, the growth in energy demand will be very rapid. Indonesia`s domestic gas demand is expected to increase form 1.6 Bcf/d (0.05 Bcm/d) in 1991 to 5.7 Bcf/d (0.2 Bcm/d) in 2021. Because the major gas resources of East Kalimantan, North Sumatra, and Natuna are so remote from the main consuming area in northwest Java and are dedicated for export by virtue of the national energy policy, the need is becoming urgent to develop new resources of natural gas, including coalbed methane, for the domestic market. Due to the high geothermal gradient, the coal deposits in the back-arc basins of Sumatra and Java are expected to be of higher than normal rank at depths favorable for coalbed methane production. The oil- and gas-productive Jatibarang sub-basin in northwest Java, with estimated in-place resources of coalbed methane in excess of 20 Tcf (0.6 Tcm), is considered to be the most prospective area in Indonesia for the near-term development of coalbed methane. This area includes Jakarta and vicinity, the most populous and most heavily industrialized part of Indonesia.

Integration Strategy for DB-MHR TRISO Fuel production in conjunction with MOX Fuel production  

SciTech Connect (OSTI)

One of the nuclear power options for the future involves the evolution of gas cooled reactors to support the likely high temperature operations needed for commercial scale hydrogen production. One such proposed option is to use a Gas Turbine Modular Helium Reactor fueled with uranium based TRISO (coated particle) fuel. It has also been suggested that such a MHR could be operated in a ''Deep Burn'' manner fueled with TRISO fuel produced from recycle spent nuclear fuel. This concept known as a DBMHR must withstand significant development and fuel fabrication cost to be economically viable. The purpose of this report is to consider and propose a strategy where synergy with a parallel MOX fuel to LWR program provides economic or other advantage for either or both programs. A strategy involving three phases has been envisioned with potential for economic benefit relative to a stand-alone TRISO/DBMHR program. Such a strategy and related timing will ultimately be driven by economics, but is offered here for consideration of value to the total AFCI program. Phase I Near-term. Conventional spent fuel aqueous processing, MOX fuel fabrication, and use of present and future LWR/ALWR's with objective of a ''Continuous Recycle'' mode of fuel cycle management. Phase II Intermediate. Augmentation of LWR/ALWR industry with MHR deployment as justified by hydrogen economy and/or electrical demand. Phase III Long-term. Introduction of DBMHR's to offer alternative method for transuranic destruction and associated repository benefits, in addition to Phase II benefits. The basic philosophy of this strategy appears sound. However, the details of the technology plans and economic evaluations should receive additional detail and evaluation in the next fiscal year as funding can support.

Large extra dimensions and cosmological problems  

Science Journals Connector (OSTI)

We consider a variant of the brane-world model in which the universe is the direct product of a Friedmann-Robertson-Walker (FRW) space and a compact hyperbolic manifold of dimension d>~2. Cosmology in this space is particularly interesting. The dynamical evolution of the space-time leads to the injection of a large entropy into the observable (FRW) universe. The exponential dependence of surface area on distance in hyperbolic geometry makes this initial entropy very large, even if the CHM has a relatively small diameter (in fundamental units). The very large statistical averaging inherent in the collapse of the initial entropy onto the brane acts to smooth out initial inhomogeneities. This smoothing is then sufficient to account for the current homogeneity of the universe. With only mild fine-tuning, the current flatness of the universe can also then be understood. Finally, recent brane-world approaches to the hierarchy problem can be readily realized within this framework.

Dirichlet problems for stationary von Neumann-Landau wave equations  

E-Print Network [OSTI]

It is known that von Neumann-Landau wave equation can present a mathematical formalism of motion of quantum mechanics, that is an extension of Schr\\"{o}dinger's wave equation. In this paper, we concern with the Dirichlet problem of the stationary von Neumann-Landau wave equation: {(- \\triangle_x + \\triangle_y) \\Phi (x, y) = 0, x, y \\in \\Omega, \\Phi|_{\\partial \\Omega \\times \\partial \\Omega} = f, where $\\Omega$ is a bounded domain in $\\mathbf{R}^n.$ By introducing anti-inner product spaces, we show the existence and uniqueness of the generalized solution for the above Dirichlet problem by functional-analytic methods.

Replies: Bacteria and yeast are very efficient with their enzyme systems. They don't make enzymes they can't use. Yeast don't have the enzymes necessary to metabolize lactose. Starch is a complex sugar and yeast needs certain enzymes to break starch down into sugar. Every chemical reaction needs its own enzyme.

Regional stocks will shift to areas of highest need, production from East Coast and Gulf Coast refineries will increase (capacity is available as the utilization indicates), and if the problem persists, imports from Europe might be drawn to U.S. But there are several caveats as to the quickness of the price response: Colder weather would quickly use up additional supply moving into the area, postponing relief for the price spike Further refinery problems and/or long delays in current East Coast refinery recoveries would slow new supply from arriving.

APT radionuclide production experiment  

SciTech Connect (OSTI)

Tritium ({sup 3}H, a heavy isotope of hydrogen) is produced by low energy neutron-induced reactions on various elements. One such reaction is n+{sup 3}He {yields}>{sup 3}H+{sup 1}H in which {sup 3}He is transmuted to tritium. Another reaction, which has been used in reactor production of tritium, is the n+{sup 6}Li {yields}> {sup 3}H+{sup 4}He reaction. Accelerator Production of Tritium relies on a high-energy proton beam to produce these neutrons using the spallation reaction, in which high-energy proton beam to produce these neutrons using the spallation reaction, in which high-energy protons reacting with a heavy nucleus produce a shower of low-energy neutrons and a lower-mass residual nucleus. It is important to quantify the residual radionuclides produced in the spallation target for two reasons. From an engineering point of view, one must understand short-lived isotopes that may contribute to decay heat. From a safety viewpoint, one must understand what nuclei and decay gammas are produced in order to design adequate shielding, to estimate ultimate waste disposal problems, and to predict possible effects due to accidental dispersion during operation. The authors have performed an experiment to measure the production of radioisotopes in stopping-length W and Pb targets irradiated by a 800 MeV proton beam, and are comparing the results to values obtained from calculations using LAHET and MCNP. The experiment was designed to pay particular attention to the short half-life radionuclides, which have not been previously measured. In the following, they present details of the experiment, explain how they analyzed the data and obtain the results, how they perform the calculations, and finally, how the experimental data agree with the calculations.

Diagnostics for multiple regression problems  

SciTech Connect (OSTI)

In the last 10 to 15 years there has been much work done in trying to improve linear regression results. Individuals have analyzed the susceptibility of least-squares results to values far removed from the center of the independent variable observations. They have studied the problem of heavy-tailed residuals, and they have studied the problem of collinearity. From these studies have come ridge regression techniques, robust regression techniques, regression on principal components, etc. However, many practitioners view these methods with suspicion (and ignorance), and prefer to continue using the usual least-squares procedures to fit their models, even though their results might not be answering the question they think. In reaction to this, statisticians are spending more time analyzing how the individual observations affect the least squares results. In the last few years approximately 10 papers and one text have appeared that address the problem of how to study the influence of the individual observations. This report is a study of the recent work done in linear regression diagnostics. It is concerned with analyzing the effect of one case at a time, since the methods to analyze this situation are relatively straight-forward and are not prohibitive computationally.

Clean production can be considered as a strategic element in manufacturing technology for present and future products in the chemical industry. Demand is focused on the development of cost-effective technologies, the optimization of processes including separation steps, alternative processes for the reduction of waste, optimization of the use of resources and improvements in production efficiency. In many cases an environmentally friendly alternative to conventional separation processes could be membrane separation. Membrane separation techniques are suitable for mixtures of liquids, gases and vapors. Some examples of successful applications in the areas of waste water treatment and vapor recovery are given. Demands, advantages and problems of separation with membranes are also discussed.

1 LOST PRODUCTION AS CONSEQUENSE OF SILICA SCALING IN CERRO  

E-Print Network [OSTI]

Mineral scale depositation occurs in many of the Cerro Prieto wells, but the main problems occurs by silica (SiO2) scale both pipes and reservoir zones close to the downhole. In Cerro Prieto geothermal field three types of scales are found; calcium carbonate (calcite), amorphous silica (SiO2), and metallic sulfides (mainly iron, and lesser lead and cooper). The scale causes lost production and it is necessary to make around 12 workover each year to recover the steam lost. When scaling problems occurred inside casing production is more easier to recover the production that scaling occurred in the reservoir zones, because it caused a skin damage (permeability decrease) in the reservoir zones close to the bottomhole. This paper analyze and discus the scaling problems and discuss the task developed to avoid and minimized the decline wells production, as to recover the production using workover alternatives.

Production-systems analysis for fractured wells  

SciTech Connect (OSTI)

Production-systems analysis has been in use for many years to design completion configurations on the basis of an expected reservoir capacity. The most common equations used for the reservoir calculations are for steady-state radial flow. Most hydraulically fractured wells require the use of an unsteady-state production simulator to predict the higher flow rates associated with the stimulated well. These high flow rates may present problems with excessive pressure drops through production tubing designed for radial-flow production. Therefore, the unsteady-state nature of fractured-well production precludes the use of steady-state radial-flow inflow performance relationships (IPR's) to calculate reservoir performance. An accurate prediction of fractured-well production must be made to design the most economically efficient production configuration. It has been suggested in the literature that a normalized reference curve can be used to generate the IPR's necessary for production-systems analysis. However, this work shows that the reference curve for fractured-well response becomes time-dependent when reservoir boundaries are considered. A general approach for constructing IPR curves is presented, and the use of an unsteady-state fractured-well-production simulator coupled with the production-systems-analysis approach is described. A field case demonstrates the application of this method to fractured wells.

Quantum geometrodynamics creates new problems  

E-Print Network [OSTI]

The development of last years in quantum geometrodynamics highlights new problems which were not obvious in its first formulation proposed by Wheeler and DeWitt. At the first stage the main task was to apply known quantization schemes to gravitational field or a certain cosmological model. This way has led to the realization of the fact that a quantum description of the Universe is impossible without implicit or explicit indication to a reference frame presented by some medium, filling the whole Universe, with its own equation of state and thermodynamical properties. Thus the questions arise, should one seek for a "privileged" reference frame or consider all the variety of gauge conditions and appropriate solutions for the wave function? It is worth noting that thermodynamical properties of such a quantum Universe would also depend on a chosen reference frame to some extent. So, we need a self-consistent quantum theoretical and thermodynamical description of the Universe.

The 3He Supply Problem  

SciTech Connect (OSTI)

One of the main uses for 3He is in gas proportional counters for neutron detection. Radiation portal monitors deployed for homeland security and non-proliferation use such detectors. Other uses of 3He are for research detectors, commercial instruments, well logging detectors, dilution refrigerators, for targets or cooling in nuclear research, and for basic research in condensed matter physics. The US supply of 3He comes almost entirely from the decay of tritium used in nuclear weapons by the US and Russia. A few other countries contribute a small amount to the world’s 3He supply. Due to the large increase in use of 3He for homeland security, the supply has dwindled, and can no longer meet the demand. This white paper reviews the problems of supply, utilization, and alternatives.

A brief study of various hydrogen production processes have been carried out. Various solar-based hydrogen production processes are assessed and compared for their merits and demerits in terms of exergy efficiency and sustainability factor. For a case study the exergy efficiency of hydrogen production process and the hydrogen system is discussed in terms of sustainability.

Russian arms conversion and its impact on the energy problem  

Science Journals Connector (OSTI)

Conversion of the Russian arms industry to civil production poses a key issue in the overall context of the problem of economic transformation. Its impact is enormous and bears upon the energy problem in several ways. If it succeeds the conversion will largely determine the nature of economic development in Russia and the CIS, influence the prospects of economic recovery in eastern Europe in a positive way, and play a substantial role in securing Russia's future place in the world economy. Because of the novel opportunities provided by market reforms, which generally increase production efficiency and enable profound structural changes towards the environmentally benign energy consumption, the consequences of arms conversion should be put under closer scrutiny. At the same time the possibility of using the idle capacity of arms industries to revamp the energy sector itself and to enhance the construction of modem infrastructures to run an efficient market economy deserves greater attention. Although great uncertainties exist when one attempts to assess the impact of arms conversion, nonetheless, new opportunities for Western investment and trade should be pointed out. Hence, one should highlight the problem as worthy of closer monitoring.

Production smoothing and buffer stock reduction for two-stage production and inventory systems  

Science Journals Connector (OSTI)

This paper deals with the problem of developing an effective push-type ordering system which can decrease the variations of production ordering and inventory levels, while taking into account forecasted error, the difference between forecasted values and the backlog quantity, in which the shortage of safety stock of component parts causes a discrepancy between production ordering and actual production levels. The ordering system is developed on the basis of an idea which combines safety stock and the weight of the feedback quantity of actual and forecasted term-end inventory levels. Some results of numerical analysis show the effects of safety stock of the component parts and the feedback control parameter of each production stage, the autocorrelation coefficient of product demand upon the amplifications of production ordering and inventory levels.

Euclidean Jordan Algebras, Hidden Actions, and $J$-Kepler Problems  

E-Print Network [OSTI]

For a {\\em simple Euclidean Jordan algebra}, let $\\mathfrak{co}$ be its conformal algebra, $\\mathscr P$ be the manifold consisting of its semi-positive rank-one elements, $C^\\infty(\\mathscr P)$ be the space of complex-valued smooth functions on $\\mathscr P$. An explicit action of $\\mathfrak{co}$ on $C^\\infty(\\mathscr P)$, referred to as the {\\em hidden action} of $\\mathfrak{co}$ on $\\mathscr P$, is exhibited. This hidden action turns out to be mathematically responsible for the existence of the Kepler problem and its recently-discovered vast generalizations, referred to as $J$-Kepler problems. The $J$-Kepler problems are then reconstructed and re-examined in terms of the unified language of Euclidean Jordan algebras. As a result, for a simple Euclidean Jordan algebra, the minimal representation of its conformal group can be realized either as the Hilbert space of bound states for its $J$-Kepler problem or as $L^2({\\mathscr P}, {1\\over r}\\mathrm{vol})$, where $\\mathrm{vol}$ is the volume form on $\\mathscr P$ and $r$ is the inner product of $x\\in \\mathscr P$ with the identity element of the Jordan algebra.

Ignition problems in scramjet testing  

SciTech Connect (OSTI)

Ignition of H{sub 2} in heated air containing H{sub 2}O, radicals, and dust was investigated for scramjet testing. Using a reduced kinetic model for H{sub 2}{minus}O{sub 2} systems, the effects of H{sub 2}O and radicals in nozzles are discussed in relation to engine testing with vitiation heaters. Analysis using linearized rate-equations suggested that the addition of O atoms was 1.5 times more effective than the addition of H atoms for ignition. This result can be applied to the problem of premature ignition caused by residual radicals and to plasma-jet igniters. Thermal and chemical effects of dust, inevitable in storage air heaters, were studied next. The effects of heat capacity and size of dust were expressed in terms of an exponential integral function. It was found that the radical termination on the surface of dust produces an effect equivalent to heat loss. The inhibition of ignition by dust may result, if the mass fraction of dust becomes 10{sup {minus}3}.

Inverse problems in multifractal analysis  

E-Print Network [OSTI]

Multifractal formalism is designed to describe the distribution at small scales of the elements of $\\mathcal M^+_c(\\R^d)$, the set of positive, finite and compactly supported Borel measures on $\\R^d$. It is valid for such a measure $\\mu$ when its Hausdorff spectrum is the upper semi-continuous function given by the concave Legendre-Fenchel transform of the free energy function $\\tau_\\mu$ associated with $\\mu$; this is the case for fundamental classes of exact dimensional measures. For any function $\\tau$ candidate to be the free energy function of some $\\mu\\in \\mathcal M^+_c(\\R^d)$, we build such a measure, exact dimensional, and obeying the multifractal formalism. This result is extended to a refined formalism considering jointly Hausdorff and packing spectra. Also, for any upper semi-continuous function candidate to be the lower Hausdorff spectrum of some exact dimensional $\\mu\\in\\mathcal M^+_c(\\R^d)$, we build such a measure. Our results transfer to the analoguous inverse problems in multifractal analysis of H\\"older continuous functions.

The retailer multi-item inventory problem with demand cannibalization and substitution  

Science Journals Connector (OSTI)

Retailers of products with limited shelf life are faced with the dilemma of stocking the right mix of standard product and its customized stock keeping units, in each product category. In this paper we model the retailer multi-item inventory problem with demand cannibalization and substitution. The model focuses on the twin problems of optimal portfolio selection as well as optimal stocking under retailing context. Owing to analytical complexity in determining optimal solution, we develop heuristics for solving the problem. Using set of numerical examples we compare the heuristic solutions against the optimal solutions. In addition, we also attempt to understand the impact of important parameters on retailer profits through a series of sensitivity analysis.

Dimuonium (the bound system of two muons, $\\mu^+\\mu^-$-atom) has not been observed yet. In this paper we discuss the electromagnetic production of dimuonium at RHIC and LHC in relativistic heavy ion collisions. The production of parastates is analyzed in the equivalent photon approximation. For the treatment of orthostates, we develop a three photon formalism. We determine the production rates at RHIC and LHC with an accuracy of a few percent and discuss problems related to the observation of dimuonium.

Constrained Graph Optimization: Interdiction and Preservation Problems  

SciTech Connect (OSTI)

The maximum flow, shortest path, and maximum matching problems are a set of basic graph problems that are critical in theoretical computer science and applications. Constrained graph optimization, a variation of these basic graph problems involving modification of the underlying graph, is equally important but sometimes significantly harder. In particular, one can explore these optimization problems with additional cost constraints. In the preservation case, the optimizer has a budget to preserve vertices or edges of a graph, preventing them from being deleted. The optimizer wants to find the best set of preserved edges/vertices in which the cost constraints are satisfied and the basic graph problems are optimized. For example, in shortest path preservation, the optimizer wants to find a set of edges/vertices within which the shortest path between two predetermined points is smallest. In interdiction problems, one deletes vertices or edges from the graph with a particular cost in order to impede the basic graph problems as much as possible (for example, delete edges/vertices to maximize the shortest path between two predetermined vertices). Applications of preservation problems include optimal road maintenance, power grid maintenance, and job scheduling, while interdiction problems are related to drug trafficking prevention, network stability assessment, and counterterrorism. Computational hardness results are presented, along with heuristic methods for approximating solutions to the matching interdiction problem. Also, efficient algorithms are presented for special cases of graphs, including on planar graphs. The graphs in many of the listed applications are planar, so these algorithms have important practical implications.

Marathon solves Brae Field's problems  

SciTech Connect (OSTI)

When Marathon Oil starts production in the South Brae field (North Sea) this summer, it will have set the following milestones: (1) The 13,500-ft reservoir is the deepest developed in the North Sea to date, (2) the topside equipment is the heaviest placed on any North Sea steel jacket, (3) the produced gas contains a large amount of liquefiable hydrocarbons and 35% carbon dioxide (4) the platforms gas-sweetening module is the first ever installed offshore, (5) reservoir temperature (240/sup 0/F) is the highest of any North Sea reservoir developed so far, (6) the entire project is one of the few in the North Sea to be completed on schedule and within the budget proposed 3 years earlier, and (7) the deck modules were virtually 100% complete before being lifted onto the jacket. Some recently drilled wells in the area have found hydrocarbons outside the reach of the platform. One of these areas, designated North Brae, appears to hold a condensate reservoir that shows promise of becoming commercial. Marathon engineers feel a strong possibility that one or more additional platforms will be needed in the area.

Animal testing of beauty products  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Animal testing of beauty products Animal testing of beauty products Name: Wayers Location: N/A Country: N/A Date: N/A Question: I consider animal testing to be cruel and unnecessary in most cases. I do not disapprove entirely with the testing of drugs and beneficial technology on animals; but I completely have a problem with testing unimportant items, such as make up, hair spray, and other beauty products on innocent lives. Are there any other methods of testing companies can use that wouldn't involve the harming of animals? Wayers Replies: Experience, theoretical models and testing on cell cultures can offer guidelines for a good guess as to what will happen when you throw some new chemical into a human body, but there are examples of where even very careful guesses have proved in practice to be terribly wrong (Thalidomide and DES come to mind). Given the very high level of safety that people demand from substances that go in or on their bodies, the only testing method that is considered reliable enough at present for new chemicals is to try the stuff out on some living creature that can tell you if it hurts or is sick. And even then you must be sure the creature is as similar as possible, at least in the part of the body you are worried about, to human beings. (This is itself a real challenge, and progress in treating disease is often hampered by the lack of a suitable animal model.) Thus ultimately comes the difficult ethical choice you are concerned with: namely, who or what gets to be the guinea pig? In terms of beauty products, there are enough people who feel as you do that there are a number of product lines which are guaranteed to be made without animal testing (they use ingredients that have been tested earlier on animals and are now recognized as safe). You can find them in natural foods and ecologically-conscious stores.

Heavy oil production from Alaska  

SciTech Connect (OSTI)

North Slope of Alaska has an estimated 40 billion barrels of heavy oil and bitumen in the shallow formations of West Sak and Ugnu. Recovering this resource economically is a technical challenge for two reasons: (1) the geophysical environment is unique, and (2) the expected recovery is a low percentage of the oil in place. The optimum advanced recovery process is still undetermined. Thermal methods would be applicable if the risks of thawing the permafrost can be minimized and the enormous heat losses reduced. Use of enriched natural gas is a probable recovery process for West Sak. Nearby Prudhoe Bay field is using its huge natural gas resources for pressure maintenance and enriched gas improved oil recovery (IOR). Use of carbon dioxide is unlikely because of dynamic miscibility problems. Major concerns for any IOR include close well spacing and its impact on the environment, asphaltene precipitation, sand production, and fines migration, in addition to other more common production problems. Studies have indicated that recovering West Sak and Lower Ugnu heavy oil is technically feasible, but its development has not been economically viable so far. Remoteness from markets and harsh Arctic climate increase production costs relative to California heavy oil or Central/South American heavy crude delivered to the U.S. Gulf Coast. A positive change in any of the key economic factors could provide the impetus for future development. Cooperation between the federal government, state of Alaska, and industry on taxation, leasing, and permitting, and an aggressive support for development of technology to improve economics is needed for these heavy oil resources to be developed.

Top address a growing national problem with generation of wastes and by-products, TVA has been involved for several years with developing and commercializing environmentally responsible practices for eliminating, minimizing, or utilizing various wastes/by-products. In many cases, reducing waste generation is impractical, but the wastes/by-products can be converted into other environmentally sound products. In some instances, conversion of safe, value-added agricultural products in the best or only practical alternative. TVA is currently involved with a diversity of projects converting wastes/by-products into safe, economical, and agriculturally beneficial products. Environmental improvement projects have involved poultry litter, cellulosic wastes, used battery acid, ammonium sulfate fines, lead smelting effluents, deep-welled sulfuric acid/ammonium bisulfate solutions, wood ash, waste magnesium ammonium sulfate slurry from recording tape production, and ammunition plant waste sodium nitrate/ammonium nitrate streams.

Science Journals Connector (OSTI)

Multicast networks are used to distribute live content, such as video or audio streams, to a potentially large number of destinations. Streaming caches are deployed in these multicast systems to allow content distribution without network overload. We consider two related problems that arise in multicast networks: the tree cache placement and the flow cache placement problems. These problems are shown to be NP-hard, and we give a proof of hardness of approximation using a gap-preserving reduction. We also present approximation algorithms, as well as special cases where these problems can be solved in polynomial time.

The real problem with Merchant transmission  

SciTech Connect (OSTI)

Current regulatory policy distinguishes transmission investments that have primarily economic benefits from those that primarily enhance reliability. But no such dichotomy exists; congestion and reliability are inter-related in complex ways. Thus, solving the transmission investment problem is more complex than ''fixing'' merchant transmission; investment in the grid must be treated as a systems problem. (author)

Method for Developing Descriptions of Hard-to-Price Products: Results of the Telecommunications Product Study  

SciTech Connect (OSTI)

This report presents the results of a study to test a new method for developing descriptions of hard-to-price products. The Bureau of Labor Statistics (BLS) is responsible for collecting data to estimate price indices such as the Consumers Price Index (BLS) is responsible for collecting data to estimate price indices such as the Consumers Price Index (CPI). BLS accomplishes this task by sending field staff to places of business to price actual products. The field staff are given product checklists to help them determine whether products found today are comparable to products priced the previous month. Prices for non-comparable products are not included in the current month's price index calculations. A serious problem facing BLS is developing product checklists for dynamic product areas, new industries, and the service sector. It is difficult to keep checklists up-to-date and quite often simply to develop checklists for service industry products. Some people estimates that upwards of 50 % of US economic activity is not accounted for in the CPI

Some formulations of these products require the inner product of two sparse vectors, which have inefficient use of cache memory. In this paper, we propose a new algorithm for computing sparse matrix-matrix products by exploiting matrix nonzero structure through the process of graph coloring. We prove the validity of this technique in general and demonstrate its viability for multigrid methods used to solve three-dimensional boundary value problems.

A Diagrammatic Approach to the Meander Problem  

E-Print Network [OSTI]

The meander problem is a combinatorial problem which provides a toy model of the compact folding of polymer chains. In this paper we study various questions relating to the enumeration of meander diagrams, using diagrammatical methods. By studying the problem of folding tree graphs, we derive a lower bound on the exponential behaviour of the number of connected meander diagrams. A different diagrammatical method, based on a non-commutative algebra, provides an approximate calculation of the behaviour of the generating functions for both meander and semi-meander diagrams.

Some Rheologic Aspects of Petroleum Production  

Science Journals Connector (OSTI)

A critical review and summary are given of some of the rheological aspects of the production and transportation of petroleum. It is shown how the proper flow characteristics of the colloidal dispersions known as drilling fluids may be controlled by chemico?physical methods and the importance of these characteristics in the technique of drilling is analyzed. The laws of flow of gas?oil mixtures through porous media are approached by a study of the permeability factor of such media and applied to the problems of ultimate production production rate effective drainage area etc. of petroleum?producing horizons. The flow of gas?liquid mixtures through pipes is discussed from the standpoint of bringing oil to the surface from the reservoir. Pipeline flow of oil is discussed with particular reference to cold weather flow for oils that exhibit thixotropic properties because of a heavy content of wax. Unsolved problems in these various fields of the rheology of petroleum production are pointed out.

Waste minimization necessary for solving wastewater problems  

SciTech Connect (OSTI)

Developing and implementing waste minimization procedures to correct the wastewater treatment problem are not as simple as identifying the problem. People cannot solve today's problems with the same kind of thinking that caused the problems. Nonetheless, industry primarily is using traditional treatment technologies to reduce wastewater. most companies are upgrading their wastewater treatment plants and installing treatment equipment in process areas whenever technically and economically feasible. The solution to ensuring wastewater compliance is recycling, waste minimization and moving toward zero discharge. Treating wastewater to the best possible quality still creates residual waste that must be disposed. In addition, regulatory limits continue to increase. Although some facilities can close and have closed the loop in certain processes, industry is pursuing waste minimization and the goal of zero discharge, given existing technology and economics. This, companies must taken an innovative approach to reducing wastewater volume and toxicity at the source.

A Landscape Analysis of Constraint Satisfaction Problems  

E-Print Network [OSTI]

We discuss an analysis of Constraint Satisfaction problems, such as Sphere Packing, K-SAT and Graph Coloring, in terms of an effective energy landscape. Several intriguing geometrical properties of the solution space become in this light familiar in terms of the well-studied ones of rugged (glassy) energy landscapes. A `benchmark' algorithm naturally suggested by this construction finds solutions in polynomial time up to a point beyond the `clustering' and in some cases even the `thermodynamic' transitions. This point has a simple geometric meaning and can be in principle determined with standard Statistical Mechanical methods, thus pushing the analytic bound up to which problems are guaranteed to be easy. We illustrate this for the graph three and four-coloring problem. For Packing problems the present discussion allows to better characterize the `J-point', proposed as a systematic definition of Random Close Packing, and to place it in the context of other theories of glasses.

We show that the answer to this problem lies in a particular characterization of gravitation. This moreover also provides a picture of a Planck scale underpinning for the entire universe itself.

Time-evolution problem in regge calculus  

Science Journals Connector (OSTI)

The simplectic approximation to Einstein's equations ("Regge calculus") is derived by considering the net to be actually a (singular) Riemannian manifold. Specific nets for open and closed spaces are introduced in terms of which one can formulate the general time-evolution problem, which thereby reduces to the repeated solution of finite sets of coupled nonlinear (algebraic) equations. The initial-value problem is also formulated in simplectic terms.

Send Evaluation Product : Sonde-Adjust Site(s) FKB GRW HFE NIM NSA PYE SGP TWP General Description The sonde-adjust VAP produces data that corrects documented biases in radiosonde humidity measurements. Unique fields contained within this datastream include smoothed original relative humidity, dry bias corrected relative humidity, and final corrected relative humidity. The smoothed RH field refines the relative humidity from integers - the resolution of the instrument - to fractions of a percent. This profile is then used to calculate the dry bias corrected field. The final correction fixes a time-lag problem and uses the dry-bias field as input into the algorithm.

Production of tetraquarks at the LHC  

Science Journals Connector (OSTI)

The high prompt production cross section of X(3872) at hadron colliders has shown to be very informative about the quark nature of the X, Y, Z states. We present here a number of results on X production in pp(p¯) collisions obtained with Monte Carlo hadronization methods and illustrate what can be learned from their use to improve our understanding of exotic states. In particular, a comparison between antideuteron and X production cross sections is proposed. Hadronization might be the key to solve the problem of the extra states expected in diquark-antidiquark models which are naturally favored after the recent confirmation of the Z(4430) tetraquark, together with its lower partners Zc(3900) and Zc?(4020).

Geological problems in radioactive waste isolation  

SciTech Connect (OSTI)

The problem of isolating radioactive wastes from the biosphere presents specialists in the fields of earth sciences with some of the most complicated problems they have ever encountered. This is especially true for high level waste (HLW) which must be isolated in the underground and away from the biosphere for thousands of years. Essentially every country that is generating electricity in nuclear power plants is faced with the problem of isolating the radioactive wastes that are produced. The general consensus is that this can be accomplished by selecting an appropriate geologic setting and carefully designing the rock repository. Much new technology is being developed to solve the problems that have been raised and there is a continuing need to publish the results of new developments for the benefit of all concerned. The 28th International Geologic Congress that was held July 9--19, 1989 in Washington, DC provided an opportunity for earth scientists to gather for detailed discussions on these problems. Workshop W3B on the subject, Geological Problems in Radioactive Waste Isolation -- A World Wide Review'' was organized by Paul A Witherspoon and Ghislain de Marsily and convened July 15--16, 1989 Reports from 19 countries have been gathered for this publication. Individual papers have been cataloged separately.

Tight Product Balance Pushes Up Product Spread (Spot Product - Crude  

Gasoline and Diesel Fuel Update (EIA)

5 5 Notes: Gasoline inventories indicate how tight the gasoline product market is in any one region. When the gasoline market is tight, it affects the portion of gasoline price is the spread between spot product price and crude oil price. Note that in late 1998-and early 1999 spreads were very small when inventories were quite high. Contrast summers of 1998 or 1999 with summer 2000. Last summer's tight markets, resulting low stocks and transition to Phase 2 RFG added price pressure over and above the already high crude price pressure on gasoline -- particularly in the Midwest. As we ended last winter, gasoline inventories were low, and the spread between spot prices and crude oil were higher than typical as a result. Inventories stayed well below average and the spread during the

Environmental implications of accelerated gasohol production: preliminary assessment  

SciTech Connect (OSTI)

This report assesses the environmental impacts of increasing US production of fuel ethanol by 330 million gallons per year in the 1980 to 1981 time frame in order to substitute gasohol for 10% of the unleaded gasoline consumed in the United States. Alternate biomass feedstocks are examined and corn is selected as the most logical feedstock, based on its availability and cost. Three corn conversion processes that could be used to attain the desired 1980 to 1981 production are identified; fermentation plants that use a feedstock of starch and wastes from an adjacent corn refining plants are found to have environmental and economic advantages. No insurmountable environmental problems can be achieved using current technology; the capital and operating costs of this control are estimated. If ethanol production is increased substantially after 1981, the environmentally acceptable use or disposal of stillage, a liquid by-product of fermentation, could become a serious problem.

SciTech Connect (OSTI)

Coal Production 1992 provides comprehensive information about US coal production, the number of mines, prices, productivity, employment, productive capacity, and recoverable reserves to a wide audience including Congress, Federal and State agencies, the coal industry, and the general public. In 1992, there were 3,439 active coal mining operations made up of all mines, preparation plants, and refuse operations. The data in Table 1 cover the 2,746 mines that produced coal, regardless of the amount of production, except for bituminous refuse mines. Tables 2 through 33 include data from the 2,852 mining operations that produced, processed, or prepared 10 thousand or more short tons of coal during the period, except for bituminous refuse, and includes preparation plants with 5 thousand or more employee hours. These mining operations accounted for over 99 percent of total US coal production and represented 83 percent of all US coal mining operations in 1992.

Low cost methodologies to analyze and correct abnormal production decline in stripper gas wells  

SciTech Connect (OSTI)

The goal of this research program is to develop and deliver a procedure guide of low cost methodologies to analyze and correct problems with stripper wells experiencing abnormal production declines. A study group of wells will provide data to determine the historic frequency of the problem of abnormal production declines in stripper gas wells and the historic frequency of the causes of the production problems. Once the most frequently occurring causes of the production problems are determined, data collection forms and decision trees will be designed to cost-effectively diagnose these problems and suggest corrective action. Finally, economic techniques to solve the most frequently occurring problems will be researched and implemented. These systematic methodologies and techniques will increase the efficiency of problem assessment and implementation of solutions for stripper gas wells. This first quarterly technical report describes the data reduction and methodology to establish a study group of stripper gas wells in which Artex Oil Company or its affiliate, Arloma Corporation, own a working or royalty interest. The report describes the procedures to define wells exhibiting abnormal decline and identify the associated problem. Finally, the report discusses initial development of diagnostic procedures to evaluate the cause of abnormal production declines.

Simple Models of the Protein Folding Problem  

E-Print Network [OSTI]

The protein folding problem has attracted an increasing attention from physicists. The problem has a flavor of statistical mechanics, but possesses the most common feature of most biological problems -- the profound effects of evolution. I will give an introduction to the problem, and then focus on some recent work concerning the so-called ``designability principle''. The designability of a structure is measured by the number of sequences that have that structure as their unique ground state. Structures differ drastically in terms of their designability; highly designable structures emerge with a number of associated sequences much larger than the average. These highly designable structures 1) possess ``proteinlike'' secondary structures and motifs, 2) are thermodynamically more stable, and 3) fold faster than other structures. These results suggest that protein structures are selected in nature because they are readily designed and stable against mutations, and that such selection simultaneously leads to thermodynamic stability and foldability. According to this picture, a key to the protein folding problem is to understand the emergence and the properties of the highly designable structures.

We address the problem of how simple a solution can be for a given quantum local consistency instance. More specifically, we investigate how small the rank of the global density operator can be if the local constraints are known to be compatible. We prove that any compatible local density operators can be satisfied by a low rank global density operator. Then we study both fermionic and bosonic versions of the N-representability problem as applications. After applying the channel-state duality, we prove that any compatible local channels can be obtained through a global quantum channel with small Kraus rank.

We investigate the strong CP problem in an SU(1,1) supergravity model possessing a nonminimal Yang-Mills kinetic energy. The noncompact U?(1)I is broken by nonperturbative QCD effects, and the axionlike field has weird properties from this symmetry breaking.
