Tertiary Storage: Current Status and Future Trends  

E-Print Network (OSTI)

This report summarizes current state of the art in tertiary storage systems. We begin with a comprehensive discussion of magnetic tape and optical storage technologies. This is followed by a classification of commercial products based on their performance characteristics. Our analysis of product data indicates that in contrast to disk technology, tertiary storage products have significant variablility in terms of data transfer rates as well as other performance figures. We then summarize efforts in the areas of operating systems, databases and advanced applications to integrate tertiary storage. We point out that different assumptions about the underlying technology result in entirely different algorithms and system design. We conclude the report with a speculation of future trends. 1 Introduction With the recent improvements in network and processor speeds, several data intensive applications have become much more feasible than ever before. Examples of such applications include digit...

Current Trends in Gamma Radiation Detection for Radiological Emergency Response  

SciTech Connect

Passive and active detection of gamma rays from shielded radioactive materials, including special nuclear materials, is an important task for any radiological emergency response organization. This article reports on the current trends and status of gamma radiation detection objectives and measurement techniques as applied to nonproliferation and radiological emergencies. In recent years, since the establishment of the Domestic Nuclear Detection Office by the Department of Homeland Security, a tremendous amount of progress has been made in detection materials (scintillators, semiconductors), imaging techniques (Compton imaging, use of active masking and hybrid imaging), data acquisition systems with digital signal processing, field programmable gate arrays and embedded isotopic analysis software (viz. gamma detector response and analysis software [GADRAS]1), fast template matching, and data fusion (merging radiological data with geo-referenced maps, digital imagery to provide better situational awareness). In this stride to progress, a significant amount of interdisciplinary research and development has taken place–techniques and spin-offs from medical science (such as x-ray radiography and tomography), materials engineering (systematic planned studies on scintillators to optimize several qualities of a good scintillator, nanoparticle applications, quantum dots, and photonic crystals, just to name a few). No trend analysis of radiation detection systems would be complete without mentioning the unprecedented strategic position taken by the National Nuclear Security Administration (NNSA) to deter, detect, and interdict illicit trafficking in nuclear and other radioactive materials across international borders and through the global maritime transportation–the so-called second line of defense.

Case studies of current trends in development geology  

SciTech Connect

Traditionally, development geologists have been responsible for studying leases, logs, and cores in detail in support of engineering functions. These responsibilities have grown from defining gross reservoir geometries to understanding subtle differences in reservoirs attributed to stratigraphic and structural complexities, depositional environments, and hydrodynamic processes. To handle these increased responsibilities, expertise has become essential in the areas of computer applications, log analysis, modeling, and management of produced water. Examples of the use and application of each area to projects from fields on the west side of the San Joaquin Valley demonstrate current techniques employed by development geologists and the evolution of a development department within Texaco. A study of a property in the South Belridge field on which 330 wells were drilled over a two-year period illustrates how computer resources have become vital in handling the vast amount of data needed to perform detailed geologic studies. Intricate geologic characterization has become essential to optimizing and defining reservoir performance in several fields: (1) Southeast Lost Hills, a complex diagenetic trap; (2) Buena Vista Hills, where log analysis is needed to make reserve estimates and step-out potential meaningful; (3) Midway-Sunset field, for which detailed geology leads to new field-wide models and future prospects. Increasing environmental concern over waste disposal has required an important involvement of development geologists in the geologic and hydrologic aspects of subsurface injection of produced water and other brines in the Santiago Creek field. Instead of providing a training ground for future explorationists, development geology should be viewed as an alternative career with potential for a much greater demand in the future.

Wind Power Development in the United States: Current Progress, Future Trends  

SciTech Connect

The U.S. wind power industry is in an era of substantial growth, with the U.S. and China likely to vie for largest-market status for years to come. With the market evolving at such a rapid pace, keeping up with current trends in the marketplace has become increasingly difficult. At the same time, limits to future growth are uncertain. This paper summarizes major trends in the U.S. wind market, and explores the technical and economic feasibility of achieving much greater levels of wind penetration. China would be well served to conduct similar analyses of the feasibility, benefits, challenges, and policy needs associated with much higher levels of wind power generation than currently expressed in national targets.

Iran`s petroleum policy: Current trends and the future outlook  

SciTech Connect

The Iranian economy and political situation have undergone radical changes since the 1979 Islamic revolution. The excesses of the early years of the revolution have gradually given way to moderation and a more pragmatic economic policy--based on the principles of the free market. The petroleum policy, as a subset of the economic policies, has been somewhat affected by the political and economic developments in Iran. The petroleum policy has changed from a position of no foreign participation to a position that includes a desire for foreign participation, the text of a model contract, and an attempt to introduce new technologies in the upstream sector. This report provides an overview of the key issues facing the Iranian oil industry and the economic context in which the oil industry is operating in Iran. It describes the evolution of policies meant to move the oil industry toward the free market; it discusses Iran`s oil trading partners, the outlook for refining and project investments, and current and likely future developments in the natural gas and petrochemical sectors. In short, the report provides an up-to-date assessment of the Iranian petroleum sector and its likely evolution in the future.

Preliminary evaluation of the performance, water use, and current application trends of evaporative coolers in California climates  

SciTech Connect

This paper describes the latest results of an ongoing analysis investigating the potential for evaporative cooling as an energy-efficient alternative to standard air-conditioning in California residences. In particular, the study uses detailed numerical models of evaporative coolers linked with the DOE-2 building energy simulation program to study the issues of indoor comfort, energy and peak demand savings with and without supplemental air-conditioning and consumptive water use. In addition, limited surveys are used to assess the current market availability of evaporative cooling in California, typical contractor practices and costs, and general acceptance of the technology among engineers, contractors, and manufacturers. The results show that evaporative coolers can provide significant energy and peak demand savings in California residences, but the impact of the increased indoor humidity on human comfort remains an unanswered question that requires further research and clarification. Evaluated against ASHRAE comfort standards developed primarily for air-conditioning both direct and two-stage evaporative coolers would not maintain comfort at peak cooling conditions due to excessive humidity. However, using bioclimatic charts that place human comfort at the 80% relative humidity line, the study suggests that direct evaporative coolers will work in mild coastal climates, while two-stage models should provide adequate comfort in Title 24 houses throughout California, except in the Imperial Valley. The study also shows that evaporative coolers will increase household water consumption by less than 6% on an annual basis, and as much as 23% during peak cooling months, and that the increases in water cost are minimal compared to the electricity savings. Lastly, a survey of engineers and contractors revealed generally positive experiences with evaporative coolers, with operational cost savings, improved comfort, unproved air quality as the primary benefits in their use.

Trends in properties of motor gasolines for the years 1942 through 1984; diesel fuels for the years 1950 through 1983; aviation fuels for the years 1947 through 1983; and heating oils for the years 1955 through 1984, have been evaluated based upon data contained in surveys prepared and published by the National Institute for Petroleum and Energy Research (NIPER) formerly the Bartlesville Energy Technology Center (BETC). The surveys for motor gasolines were conducted under a cooperative agreement with the Coordinating Research Council (CRC) and the Bureau of Mines from 1935 through 1948 and in cooperation with the American Petroleum Institute (API) since 1948 for all surveys. The motor gasoline surveys have been published twice annually since 1935 describing the properties of motor gasolines throughout the country. Other surveys prepared in cooperation with API and the Bureau of Mines, the Energy Research and Development Administration, the Department of Energy, and currently NIPER were aviation gasolines beginning in 1947, diesel fuels in 1950, aviation turbine fuels in 1951, and heating oils, formerly burner fuel oils, in 1955. Various companies throughout the country obtain samples of motor gasolines from retail outlets and refinery samples for the other surveys, and analyze the samples using American Society for Testing and Materials (ASTM) procedures. The analytical data are sent to the Bartlesville Center for survey preparation and distribution. A summary report has been assembled from data in 83 semiannual surveys for motor gasolines that shows trends throughout the entire era from winter 19

A Comparison of the Demographic Characteristics, Movtiations for Fishing, and Consumptive Orientation of Texas Urban and Rural Anglers  

E-Print Network (OSTI)

Sales of Texas fishing licenses have declined since 1988. Several authors have suggested that this decline is related to changes in the demographic characteristics of the Texas population, including increasing urbanization. As urban residents have been shown to participate in fishing less frequently than rural residents, the population of Texas residents most likely to engage in angling has declined accordingly. Based on these population trends, urban resident anglers (urban anglers) may represent the future of fishing. Information on urban anglers? demographic characteristics, motivations for fishing and consumptive orientation may be used to tailor and modify programs and policies targeting urban anglers. The purpose of this thesis was to identify differences between urban and rural anglers and to determine if the two groups were distinct from so-called average anglers. The thesis utilized data from the 2002 Statewide Survey of Texas Anglers. The independent variable, residency, was determined on the basis of United States Census Bureau criteria. Dependent variables included demographic variables (e.g., gender, age, race/ethnicity, and income), motivations for fishing, and consumptive orientation. Analysis of variance (ANOVA) and Kruskal-Wallis tests were used to compare mean ii scores among the three groups. The study found differences among urban anglers, rural anglers, and anglers in general in terms of their demographic variables, motivations for fishing, and consumptive orientation. The thesis also shows that by managing resources for average anglers, agencies may be ignoring important (and growing) constituencies.

Automotive materials usage trends  

SciTech Connect

The materials composition of US passenger cars is traced from 1960 and projected into 1990's. Sales-weighted average vehicle-weight trends are analyzed in terms of shifts in the large/small car mix, downsizing, and downweighting. The growth in the usage of lightweight materials: -high strength steels, cast/wrought aluminum, plastics and composites - are examined in detail. Usage trends in a host of other materials such as alloy steels, zinc, lead, copper, etc. are also discussed. An approximate quantitative analysis of changes in the usage of steel by the automotive industry worldwide show that about 10% of total decline in Western-World steel consumption is accounted for by the automotive industry. An assessment is presented for automotive industry use of critical materials such as chromium in alloy steels/cast irons and the platinum group metals in exhaust-gas catalysts. 10 references, 13 figures, 9 tables.

Trends in motor gasolines: 1942-1981  

Science Conference Proceedings (OSTI)

Trends in motor gasolines for the years of 1942 through 1981 have been evaluated based upon data contained in surveys that have been prepared and published by the Bartlesville Energy Technology Center (BETC). These surveys have been published twice annually since 1935 describing the properties of motor gasolines from throughout the country. The surveys have been conducted in cooperation with the American Petroleum Institute (API) since 1948. Various companies from throughout the country obtain samples from retail outlets, analyze the samples by the American Society for Testing and Materials (ASTM) procedures, and report data to the Bartlesville center for compilation, tabulation, calculation, analysis and publication. A typical motor gasoline report covers 2400 samples from service stations throughout the country representing some 48 companies that manufacture and supply gasoline. The reports include trend charts, octane plots, and tables of test results from about a dozen different tests. From these data in 77 semiannual surveys, a summary report has thus been assembled that shows trends in motor gasolines throughout the entire era of winter 1942 to 1943 to the present. Trends of physical properties including octane numbers, antiknock ratings, distillation temperatures, Reid vapor pressure, sulfur and lead content are tabulated, plotted and discussed in the current report. Also included are trend effects of technological advances and the interactions of engine design, societal and political events and prices upon motor gasoline evolution during the 40 year period.

Current trends in Latin America and the Argentine perspective  

SciTech Connect

The authors discusses the changes that are taking place in Argentina as well as in all of Latin America today -- privatization, deregulation, and the modernization of the economy, changes which will serve to strengthen the governments and provide a better quality of life for all of them. He gives an insight into the factors which helped bring about these changes, the support they are receiving, the problems which persist, and the measures that still must be taken so that these positive changes remain in place. He offers some useful information that will perhaps contribute to their understanding of the vast area which he refers to as Latin America, and more specifically, gives a thumbnail sketch of what is happening today in the Republic of Argentina. For many years now, Latin American leaders have travelled to other parts of the world and spoken about the plans and expectations for the region`s future. When these well-intentioned projects and plans never materialized, partners and supporters in the United States and other countries were frustrated and disappointed by the failure to make things work. The author`s intention here today is to describe things as they are, not as they might be, to tell about what is already happening in the sphere of business and growth of the economies in Latin America.

Labor market trends for health physicists  

Science Conference Proceedings (OSTI)

Information is presented on the recent trends in enrollments, degrees and US civilian, non-medical employment for health physicists. This information is combined with other data such as salary comparisons, indicators of hiring difficulties by the federal government, and information received from employers to assess the current labor market status for health physicists. This information indicates that for the last several years demands for new graduate health physicists have been greater than supplies. An assessment of projected enrollment and degree trends and employment trends through the mid-1990s is presented. This assessment indicates that the current labor market situation is not likely to change -- the number of job openings will continue to exceed the number of new graduates available for employment. Moreover, information is presented which indicates that there are several factors at work in the general economy which will make is difficult to enhance health physics enrollments and degrees. Thus, while the recent increase in enrollments in health physics programs and the addition of two new programs in 1990 is encouraging, these are not enough to meet future employment needs. Employers will, in all likelihood, continue to have difficulties in hiring health physicists, and salaries will continue to be relatively high through the mid-1990s. 16 refs., 8 figs.

Improving Demographic Components of Integrated Assessment Models: The Effect of Changes in Population Composition by Household Characteristics  

SciTech Connect

This report describes results of the research project on "Improving Demographic Components of Integrated Assessment Models: The Effect of Changes in Population Composition by Household Characteristics". The overall objective of this project was to improve projections of energy demand and associated greenhouse gas emissions by taking into account demographic factors currently not incorporated in Integrated Assessment Models (IAMs) of global climate change. We proposed to examine the potential magnitude of effects on energy demand of changes in the composition of populations by household characteristics for three countries: the U.S., China, and Indonesia. For each country, we planned to analyze household energy use survey data to estimate relationships between household characteristics and energy use; develop a new set of detailed household projections for each country; and combine these analyses to produce new projections of energy demand illustrating the potential importance of consideration of households.

Recent years have seen a surge of studies of the elemental abundance trends in the disks using high resolution spectroscopy. Here I will review and discuss the currently available data. Special focus will also be put on how we define stars to be members of either disk, and how current models of galaxy formation favour that thick disks are formed from several accreted bodies. The ability for the stellar abundance trends to test such predictions are discussed.

Utility Marketing Strategies & Pricing Trends  

E-Print Network (OSTI)

Marketing seems to have come out of the utility closet once again, but it is a far sight different from that of the 1970s. While some are still on a “sell, Sell, SELL!” campaign, most are soberly looking at their customers from a different perspective. They are concerned about losing them to other service territories or seeing them vanish to domestic and foreign competition. There is a sense of a “strategic alliance” being sought by the most proactive of utilities in which they become allies of their customers. In this sense, the issue of how much these customers purchased from them vanishes into the shadows of the more important elements of the relationships. Oh sure, there still are some pushing technology as the customer’s answer. And there are others using incentive and other rate gambits to develop strategic load building. But there is a definite trend emerging toward building the relationship for the long haul and putting short range profit or number game objectives on the back burner. This paper investigates the most successful current utility marketing postures, how they are changing, where pricing fits in and what we are likely to see within the next few years. We will also illustrate the potential traps in competitive marketing and customer service that still lie in wait. We still see a major number of current marketing efforts that are unbalanced, unfairly reward luck, are wasteful and counterproductive. As many of you know, we strongly believe marketing must move from technology-based, “silver bullet” competition, frenetic non-competitive load retention dissipation and load claiming to relational-based marketing in which absolute integrity and service and their consequent trust become paramount. We believe utilities must build honest relationships with all their customers, not merely their energy purchasers. These include their fuel suppliers and regulators. When a utility is not trusted, the competitive situation is reduced to that of a commodity supplier in which price and terms constitute the whole of the relationship. Utilities reduced to this level of inadequate customer service ultimately will lose to those that recognize the alternative of adding value. As the nature and consequences of competition increase, so does the importance of breaking from the methods of the past.

Bakken Shale Oil Production Trends  

E-Print Network (OSTI)

As the conventional reservoirs decrease in discovering, producing and reserving, unconventional reservoirs are more remarkable in terms of discovering, development and having more reserve. More fields have been discovered where Barnett Shale and Bakken Shale are the most recently unconventional reservoir examples. Shale reservoirs are typically considered self-sourcing and have very low permeability ranging from 10-100 nanodarcies. Over the past few decades, numerous research projects and developments have been studied, but it seems there is still some contention and misunderstanding surrounding shale reservoirs. One of the largest shale in the United State is the Bakken Shale play. This study will describe the primary geologic characteristics, field development history, reservoir properties,and especially production trends, over the Bakken Shale play. Data are available for over hundred wells from different companies. Most production data come from the Production Data Application (HDPI) database and in the format of monthly production for oil, water and gas. Additional 95 well data including daily production rate, completion, Pressure Volume Temperature (PVT), pressure data are given from companies who sponsor for this research study. This study finds that there are three Types of well production trends in the Bakken formation. Each decline curve characteristic has an important meaning to the production trend of the Bakken Shale play. In the Type I production trend, the reservoir pressure drops below bubble point pressure and gas releasingout of the solution. With the Type II production trend, oil flows linearly from the matrix into the fracture system, either natural fracture or hydraulic fracture. Reservoir pressure is higher than the bubble point pressure during the producing time and oil flows as a single phase throughout the production period of the well. A Type III production trend typically has scattering production data from wells with a different Type of trend. It is difficult to study this Type of behavior because of scattering data, which leads to erroneous interpretation for the analysis. These production Types, especially Types I and II will give a new type curve matches for shale oil wells above or below the bubble point.

Industrial Energy Efficiency Programs: Development and Trends  

E-Print Network (OSTI)

As more states establish Energy Efficiency Resource Standards (EERS), goals for energy efficiency savings are increasing across the country. Increasingly, states are relying on their industrial energy efficiency programs to find and help implement those savings. Historically, industrial energy efficiency programs have not been completely effective at finding those savings, in large part because the programs have not been flexible enough to accommodate the heterogeneous needs and unique characteristics of the industrial sector. This paper will discuss the state of industrial energy efficiency programs today. Relying on an ACEEE-administered survey of 35 industrial energy efficiency programs, we will determine current trends and challenges, address emerging needs, and identify best practices in the administration of today's industrial efficiency programs. The paper will serve as an update on industrial energy efficiency program activities and discuss the ways in which today's programs are trying to serve their industrial clients better.

Vehicle trends and future gasoline needs  

Science Conference Proceedings (OSTI)

The passenger car continues to change at a rapid pace, responding both to customers' preferences and to regulations. Vehicle trends place demands on the powertrain for high specific output, efficiency and reliability. Engine design and calibration must be optimized to utilize available fuel octane fully since low speed knock remains a significant constraint. Emerging capabilities for engine control provide flexible, adaptive approaches for fuel/engine matching. Recent, substantial increases in fuel volatility raise concerns for both driveability and emissions. Expanded use of fuel injection will be helpful for future vehicles, but new problems have appeared, and tighter definition of gasoline properties will be needed. The high sensitivity of fuel systems and emission controls to fuel quality is demonstrated by injector deposits and plugged catalysts. Dependable gasoline quality is essential. High standards of quality and reliability are necessary for fuel and lubricant products. The precision offered by current emission control systems can only be achieved with fuels that are properly prepared and marketed.

Trends for Outer Disk Profiles  

E-Print Network (OSTI)

The surface-brightness profiles of galaxy disks fall into three main classes, based on whether they are simple exponentials (Type I), bend down at large radii (Type II, "truncations") or bend up at large radii (Type III, "antitruncations"). Here, we discuss how the frequency of these different profiles depends on Hubble type, environment, and the presence or absence of bars; these trends may herald important new tests for disk formation models.

Relationship of technology level of progress to school district demographic variables  

E-Print Network (OSTI)

An exploratory study, using Texas public school district data, was conducted to determine the relationship between each of two demographic characteristics, student enrollment and the percentage of economically disadvantaged students, and the technology level of progress. In addition, the relationship between the two demographic characteristics, taken together, and the technology level of progress was investigated. The researcher found that across each of the six Educator Preparation and Development (EPD) focus areas, student enrollment, and the percentage of economically disadvantaged students were not related to the technology level of progress. The researcher also found that there was no meaningful multivariate relationship for linking student enrollment and the percentage of economically disadvantaged students, taken together, to the technology level of progress. A major finding that emerged from the analyses was the fact that the majority of school districts across the student enrollment and percentage of economically disadvantaged students categories were at the same level of technology progress, Developing Tech. Moreover, the percent of school districts not progressing beyond theDeveloping Tech level was differential for each of the six EPD focus areas. Two conclusions emerged from the empirical evidence. First, although the Target Tech level percentages were all small, two of the 20 types of Texas school districts consistently yielded the highest percents across the six EPD focus areas. These were school district type four (SE Under 500, PEDS 75% or Greater) and school district type twelve (SE 1,001-5,000, PEDS 75% or Greater). Second and more significant in terms of creating future interventions, programs, and incentives, empirical evidence in this study suggests that much work still remains to be done if all Texas school districts are to reach the ultimate objective where all school districts reach the Target Tech level on all six focus areas. The current study informs the digital divide literature as it relates to school district characteristics. The findings from this study suggest that long-range technology planning and funding initiatives in recent years have been successful, in beginning to address digital divide issues related to Educator Preparation and Development technology progress in public school districts.

Trends in electric power technologies  

SciTech Connect

Research and development (R and D) on power plants is now aimed at increasing plant efficiency and reliability to avoid the high capital costs of new plant construction. The trend toward larger generating plants makes efficiency and reliability even more important. Studies include ways to improve operator judgment and minimize error by feeding continuous in-plant information into models of plant subsystems, efforts to improve fuel conversion efficiency by studying higher-temperature thermodynamics, ways to replace existing generators with superconducting generators, and to meet environmental needs with atmospheric fluidized-bed combustion. As fuel costs rise, the US will shift more toward coal and nuclear plants, with research aimed at optimizing performance. (DCK)

E-Print Network (OSTI)

mpanies must understand the latest trends in global outsourcing. Recommendations Companies should not rush into offshore or nearshore outsourcing relationships without first understanding how to approach the endeavor (see Planning Assumption, Critical Success Factors for Offshore Outsourcing, Stephanie Moore). Global outsourcing is a complex undertaking that requires significant investment in knowledge acquisition and program management (see IdeaByte, Increasing Acceptance of Remote Programming and Maintenance Resources, Stephanie Moore, and IdeaByte, Organizing for Outsourcing: Offshore Governance, Stephanie Moore). To simplify this effort and increase the chance for success, companies should engage with vendors that have strong relationship and engagement management capabilities. For nearshore outsourcing at a low price point, companies should consider Mexico and Canada. Vendors in these countries can be viable near shore outsourcing alternatives, such as IBM Global Services (Mexic

Recent trends in automobile recycling: An energy and economic assessment  

SciTech Connect

Recent and anticipated trends in the material composition of domestic and imported automobiles and the increasing cost of landfilling the non-recyclable portion of automobiles (automobile shredder residue or ASR) pose questions about the future of automobile recycling. This report documents the findings of a study sponsored by the US Department of Energy`s Office of Environmental Analysis to examine the impacts of these and other relevant trends on the life-cycle energy consumption of automobiles and on the economic viability of the domestic automobile recycling industry. More specifically, the study (1) reviewed the status of the automobile recycling industry in the United States, including the current technologies used to process scrapped automobiles and the challenges facing the automobile recycling industry; (2) examined the current status and future trends of automobile recycling in Europe and Japan, with the objectives of identifying ``lessons learned`` and pinpointing differences between those areas and the United States; (3) developed estimates of the energy system impacts of the recycling status quo and projections of the probable energy impacts of alternative technical and institutional approaches to recycling; and (4) identified the key policy questions that will determine the future economic viability of automobile shredder facilities in the United States.

Nuclear Proliferation Technology Trends Analysis  

SciTech Connect

A process is underway to develop mature, integrated methodologies to address nonproliferation issues. A variety of methodologies (both qualitative and quantitative) are being considered. All have one thing in common, a need for a consistent set of proliferation related data that can be used as a basis for application. One approach to providing a basis for predicting and evaluating future proliferation events is to understand past proliferation events, that is, the different paths that have actually been taken to acquire or attempt to acquire special nuclear material. In order to provide this information, this report describing previous material acquisition activities (obtained from open source material) has been prepared. This report describes how, based on an evaluation of historical trends in nuclear technology development, conclusions can be reached concerning: (1) The length of time it takes to acquire a technology; (2) The length of time it takes for production of special nuclear material to begin; and (3) The type of approaches taken for acquiring the technology. In addition to examining time constants, the report is intended to provide information that could be used to support the use of the different non-proliferation analysis methodologies. Accordingly, each section includes: (1) Technology description; (2) Technology origin; (3) Basic theory; (4) Important components/materials; (5) Technology development; (6) Technological difficulties involved in use; (7) Changes/improvements in technology; (8) Countries that have used/attempted to use the technology; (9) Technology Information; (10) Acquisition approaches; (11) Time constants for technology development; and (12) Required Concurrent Technologies.

Science Conference Proceedings (OSTI)

The U.S. Nuclear Regulatory Commission's (NRC) conducts human factors engineering (HFE) safety reviews of applicant submittals for new plants and for changes to existing plants. The reviews include the evaluation of the methods and tools (M&T) used by applicants as part of their HFE program. The technology used to perform HFE activities has been rapidly evolving, resulting in a whole new generation of HFE M&Ts. The objectives of this research were to identify the current trends in HFE methods and tools, determine their applicability to NRC safety reviews, and identify topics for which the NRC may need additional guidance to support the NRC's safety reviews. We conducted a survey that identified over 100 new HFE M&Ts. The M&Ts were assessed to identify general trends. Seven trends were identified: Computer Applications for Performing Traditional Analyses, Computer-Aided Design, Integration of HFE Methods and Tools, Rapid Development Engineering, Analysis of Cognitive Tasks, Use of Virtual Environments and Visualizations, and Application of Human Performance Models. We assessed each trend to determine its applicability to the NRC's review by considering (1) whether the nuclear industry is making use of M&Ts for each trend, and (2) whether M&Ts reflecting the trend can be reviewed using the current design review guidance. We concluded that M&T trends that are applicable to the commercial nuclear industry and are expected to impact safety reviews may be considered for review guidance development. Three trends fell into this category: Analysis of Cognitive Tasks, Use of Virtual Environments and Visualizations, and Application of Human Performance Models. The other trends do not need to be addressed at this time.

Analysis of major trends in U.S. commercial trucking, 1977-2002.  

DOE Green Energy (OSTI)

This report focuses on various major long-range (1977-2002) and intermediate-range (1982-2002) U.S. commercial trucking trends. The primary sources of data for this period were the U.S. Bureau of the Census Vehicle Inventory and Use Survey and Truck Inventory and Use Survey. In addition, selected 1977-2002 data from the U.S. Department of Energy/Energy Information Administration and from the U.S. Department of Transportation/Federal Highway Administration's Highway Statistics were used. The report analyzes (1) overall gasoline and diesel fuel consumption patterns by passenger vehicles and trucks and (2) the population changes and fuels used by all commercial truck classes by selected truck type (single unit or combination), during specified time periods, with cargo-hauling commercial trucks given special emphasis. It also assesses trends in selected vehicle miles traveled, gallons per vehicle miles traveled, and gallons per cargo ton-mile traveled, as well as the effect of cargo tons per truck on fuel consumption. In addition, the report examines long-range trends for related factors (e.g., long-haul mileages driven by heavy trucks) and their impacts on reducing fuel consumption per cargo-ton-mile and the relative shares of total commercial fuel use among truck classes. It identifies the effects of these trends on U.S. petroleum consumption. The report also discusses basic engineering design and performance, national legislation on interstate highway construction, national demographic trends (e.g., suburbanization), and changes in U.S. corporate operations requirements, and it highlights their impacts on both the long-distance hauling and shorter-distance urban and suburban delivery markets of the commercial trucking industry.

REFERRED WATERFLOOD MANAGEMENT PRACTICES FOR THE SPRABERRY TREND AREA  

Science Conference Proceedings (OSTI)

This report describes the work performed during the first semi-annual third year of the project, ''Preferred Waterflood Management Practices for the Spraberry Trend Area''. The objective of this project is to significantly increase field-wide production in the Spraberry Trend in a short time frame through the application of preferred practices for managing and optimizing water injection. Our goal is to dispel negative attitudes and lack of confidence in water injection and to document the methodology and results for public dissemination to motivate waterflood expansion in the Spraberry Trend. To achieve this objective, in this period we concentrated our effort on analyzing production and injection data to optimize the reservoir management strategies for Germania Spraberry Unit. This study address the reservoir characterization and monitoring of the waterflooding project and propose alternatives of development of the current and future conditions of the reservoir to improve field performance. This research should serve as a guide for future work in reservoir simulation and can be used to evaluate various scenarios for additional development as well as to optimize the operating practices in the field. The results indicate that under the current conditions, a total of 1.410 million barrels of oil can be produced in the next 20 years through the 64 active wells and suggest that the unit can be successfully flooded with the current injection rate of 1600 BWPD and the pattern consisting of 6 injection wells aligned about 36 degrees respect to the major fracture orientation. In addition, a progress report on GSU waterflood pilot is reported for this period.

Engineering salary trends in the petroleum industry  

Science Conference Proceedings (OSTI)

To understand the changes that occur cyclically in engineering manpower supply/demand trends in the petroleum industry, it is desirable to have an awareness of some of the major activities and factors affecting such trends; of starting Petroleum Engineering salaries relating to that background; of the on-going engineering salary status which developed from these activities; and of the large effect that high starting and on-going salaries do have in attracting and retaining engineers within the petroleum industry. It is important to realize that changes in industry trends can be brought about both by economic and political decisions, in both domestic and international activities.

DEMOGRAPHICS OF THE GALAXIES HOSTING SHORT-DURATION GAMMA-RAY BURSTS  

Science Conference Proceedings (OSTI)

We present observations of the afterglows and host galaxies of three short-duration gamma-ray bursts (GRBs): 100625A, 101219A, and 110112A. We find that GRB 100625A occurred in a z = 0.452 early-type galaxy with a stellar mass of Almost-Equal-To 4.6 Multiplication-Sign 10{sup 9} M{sub Sun} and a stellar population age of Almost-Equal-To 0.7 Gyr, and GRB 101219A originated in a star-forming galaxy at z = 0.718 with a stellar mass of Almost-Equal-To 1.4 Multiplication-Sign 10{sup 9} M{sub Sun }, a star formation rate of Almost-Equal-To 16 M{sub Sun} yr{sup -1}, and a stellar population age of Almost-Equal-To 50 Myr. We also report the discovery of the optical afterglow of GRB 110112A, which lacks a coincident host galaxy to i {approx}> 26 mag, and we cannot conclusively identify any field galaxy as a possible host. From afterglow modeling, the bursts have inferred circumburst densities of Almost-Equal-To 10{sup -4}-1 cm{sup -3} and isotropic-equivalent gamma-ray and kinetic energies of Almost-Equal-To 10{sup 50}-10{sup 51} erg. These three events highlight the diversity of galactic environments that host short GRBs. To quantify this diversity, we use the sample of 36 Swift short GRBs with robust associations to an environment ({approx}1/2 of 68 short bursts detected by Swift to 2012 May) and classify bursts originating from four types of environments: late-type ( Almost-Equal-To 50%), early-type ( Almost-Equal-To 15%), inconclusive ( Almost-Equal-To 20%), and ''host-less'' (lacking a coincident host galaxy to limits of {approx}> 26 mag; Almost-Equal-To 15%). To find likely ranges for the true late- and early-type fractions, we assign each of the host-less bursts to either the late- or early-type category using probabilistic arguments and consider the scenario that all hosts in the inconclusive category are early-type galaxies to set an upper bound on the early-type fraction. We calculate most likely ranges for the late- and early-type fractions of Almost-Equal-To 60%-80% and Almost-Equal-To 20%-40%, respectively. We find no clear trend between gamma-ray duration and host type. We also find no change to the fractions when excluding events recently claimed as possible contaminants from the long GRB/collapsar population. Our reported demographics are consistent with a short GRB rate driven by both stellar mass and star formation.

Has there been an identifiable trend toward cooking less in the 1990s, or have cooking habits remained relatively constant over that period? And what characteristics of American households can be seen to influence their cooking patterns? The Residential Energy Consumption Survey (RECS) collects data on household characteristics as well as on residential energy consumption. The first RECS was conducted in 1978 and the eleventh and most recent survey was conducted in 2001. This report will refer to data collected in the 1993 and 2001 RECS.

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

Benchmarking Benchmarking The U.S. Environmental Protection Agency's (EPA) ENERGY STAR Portfolio Manager is changing the way organizations track and manage energy. As of December 2011, organizations have used Portfolio Manager to track and manage the energy use of over 260,000 buildings across all 50 states, representing over 28 billion square feet (nearly 40% of the commercial market). Because of this widespread market adoption, EPA has prepared the DataTrends series to examine benchmarking and trends in energy and water consumption in Portfolio Manager. To learn more, visit www.energystar.gov/DataTrends. Many different types of organizations use Portfolio Manager to benchmark the energy use of their buildings. Office, K-12

Condensation temperature trends among stars with planets  

E-Print Network (OSTI)

Results from detailed spectroscopic analyses of stars hosting massive planets are employed to search for trends between abundances and condensation temperatures. The elements C, S, Na, Mg, Al, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni and Zn are included in the analysis of 64 stars with planets and 33 comparison stars. No significant trends are evident in the data. This null result suggests that accretion of rocky material onto the photospheres of stars with planets is not the primary explanation for their high metallicities. However, the differences between the solar photospheric and meteoritic abundances do display a weak but significant trend with condensation temperature. This suggests that the metallicity of the sun's envelope has been enriched relative to its interior by about 0.07 dex.

Simulation of the Lattice QCD and Technological Trends in Computation  

E-Print Network (OSTI)

Simulation of Lattice QCD is a challenging computational problem. Currently, technological trends in computation show multiple divergent models of computation. We are witnessing homogeneous multi-core architectures, the use of accelerator on-chip or off-chip, in addition to the traditional architectural models. On the verge of this technological abundance, assessing the performance trade-offs of computing nodes based on these technologies is of crucial importance to many scientific computing applications. In this study, we focus on assessing the efficiency and the performance expected for the Lattice QCD problem on representative architectures and we project the expected improvement on these architectures and their impact on performance for Lattice QCD. We additionally try to pinpoint the limiting factors for performance on these architectures.

The time taken to analyze the data and obtain fast results depends on high computational power. The main advantage of using GPU(Graphic Processor Unit) programming over traditional CPU one is that graphical cards bring a lot of computing power at a very low price. Today a huge number of application(scientific, financial etc) began to be ported or developed for GPU, including Monte Carlo tools or data analysis tools for High Energy Physics.

Demographic profiles associated with academic performance for third grade students in North Forest and Aldine Independent School Districts in Texas  

E-Print Network (OSTI)

The study examined the demographic profiles associated with academic performance for third grade students in North Forest and Aldine Independent School Districts (ISDs) in Texas. Specifically, the study showed the impact that gender, ethnicity, and whether students receive free or reduced lunch (parent income level), had on third grade reading Texas Assessment of Academic Skills (TAAS) scores. The population for this study was 368 of the 9,007 third grade students from both the North Forest and Aldine Independent School Districts. Students in this study were of the predominant ethnicities at the schools: Black, Hispanic, and White. Utilizing this sample size allowed the study results to be generalized as trend data for all third grade students in the two districts. Data were collected during the spring semester of the 2002-2003 school year. Information for the study was provided through the Public Education Information Management System (PEIMS) and Academic Excellence Indicator System (AEIS) reports of both school districts. Results showed that gender does not relate to the TAAS score in North Forest, but the income level is related to third grade reading TAAS performance. Income showed a significant relationship in that North Forest had a higher percentage of students receiving free and reduced lunch. This impacted the third grade TAAS reading scores. Gender was significantly related to third grade TAAS performances at Aldine ISD in that Aldine had 66 more girls to take the test than boys. There were only 54 boys who took the test. Gender had no significance in North Forest ISD because there was an even number of girls and boys who took the test. Ethnicity would not be analyzed at North Forest ISD due to the small percentage of non-Black students in the third grade. At Aldine ISD, no relationship was found between ethnicity and third grade TAAS performers. The success rate on third grade TAAS was significantly higher at Aldine ISD (percent passed 85.1) than at North Forest ISD (percent passed 39.6).

Evaluation of Appliance Price Trends Evaluation of Appliance Price Trends Title Retrospective Evaluation of Appliance Price Trends Publication Type Journal Article Year of Publication 2009 Authors Dale, Larry L., Camille Antinori, Michael A. McNeil, James E. McMahon, and Sydny K. Fujita Journal Energy Policy Volume 37 Issue 2 Pagination 597-605 Date Published November 20 Keywords appliance efficiency standards, price forecasts, EES-EG Abstract Real prices of major appliances (refrigerators, dishwashers, heating and cooling equipment) have been falling since the late 1970s despite increases in appliance efficiency and other quality variables. This paper demonstrates that historic increases in efficiency over time, including those resulting from minimum efficiency standards, incur smaller price increases than were expected by the Department of Energy (DOE) forecasts made in conjunction with standards. This effect can be explained by technological innovation, which lowers the cost of efficiency, and by market changes contributing to lower markups and economies of scale in production of higher efficiency units. We reach four principal conclusions about appliance trends and retail price setting:1. For the past several decades, the retail price of appliances has been steadily falling while efficiency has been increasing.2. Past retail price predictions made by the DOE analyses of efficiency standards, assuming constant prices over time, have tended to overestimate retail prices.3. The average incremental price to increase appliance efficiency has declined over time. DOE technical support documents have typically overestimated this incremental price and retail prices.4. Changes in retail markups and economies of scale in production of more efficient appliances may have contributed to declines in prices of efficient appliances.

Estimating the economic and demographic impacts of solar technology commercialization on US regions  

DOE Green Energy (OSTI)

The purpose of this study is to develop a framework through which these regional economic and demographic impacts of solar technology commercialization can be analyzed. Two models comprise the basis of this framework - a national input/output model and an interregional econometric model, the National-Regional Impact Evaluation System (NRIES). These models are used to convert projected sales of solar energy systems to gross output concepts, and to evaluate the impacts associated with these sales. Analysis is provided for the nine census regions and 50 states and the District of Columbia for the years 1980 through 1990. Impacts on major economic aggregates such as output, employment, income, and population are described. The methodology used in this study is described. The economic and demographic impacts of solar technology commercialization on US regions and states are presented. The major conclusions of the study are summarized, and direction is provided for further research. Detailed tables of regional and state solar energy expenditures and their impacts appear in the Appendix.

Transportation Energy Efficiency Trends, 1972--1992  

SciTech Connect

The US transportation sector, which remains 97% dependent on petroleum, used a record 22.8 quads of energy in 1993. Though growing much more slowly than the economy from 1975 to 1985, energy use for transportation is now growing at nearly the same rate as GDP. This report describes the analysis of trends in energy use and energy intensity in transportation into components due to, (1) growth in transportation activity, (2) changes in energy intensity, and (3) changes in the modal structure of transportation activities.

Overall, the wind industry is experiencing long-term decreases in the cost to produce wind-generated electricity (Figure 1), despite recent short-term increases in upfront equipment costs. Even in the short term, however, the effect of increases in up-front capital costs on the cost of energy from wind power projects has been dampened by improvements in energy capture from the wind and decreases in operating and maintenance costs.

Beam current sensor  

DOE Patents (OSTI)

A current sensor for measuring the dc component of a beam of charged particles employs a superconducting pick-up loop probe, with twisted superconducting leads in combination with a Superconducting Quantum Interference Device (SQUID) detector. The pick-up probe is in the form of a single-turn loop, or a cylindrical toroid, through which the beam is directed and within which a first magnetic flux is excluded by the Meisner effect. The SQUID detector acts as a flux-to-voltage converter in providing a current to the pick-up loop so as to establish a second magnetic flux within the electrode which nulls out the first magnetic flux. A feedback voltage within the SQUID detector represents the beam current of the particles which transit the pick-up loop. Meisner effect currents prevent changes in the magnetic field within the toroidal pick-up loop and produce a current signal independent of the beam's cross-section and its position within the toroid, while the combination of superconducting elements provides current measurement sensitivities in the nano-ampere range.

Applying Spatiotemporal and Demographic Data to Locate Next Crime Location Control #7501  

E-Print Network (OSTI)

Geographic profiling is a tool used by law enforcement to predict the location of a serial criminal’s next crime. A typical geographic profile outputs estimated probabilities with the input of time and location of previous crimes. In this paper, we develop a new geographic profile that is able to incorporate demographical observations while remaining an effective predictor. We assume that (1) there are buffer zones around previous crime scenes because the criminal fears capture, (2) there is distance decay as criminals prefer something about the locations where previous crimes were committed, and (3) criminals target potential victims based on income and (4) target areas based on crime rate, which are claims supported by research of serial criminals. In order to find an effective profile, we have combined two models of criminal behavior which predict the location of future crime. First, we compute probability densities using a time-weighted kernel density algorithm, which includes buffer zone

The Hanford Site New Production Reactor (NPR) economic and demographic baseline forecasts  

SciTech Connect

The objective of this is to present baseline employment and population forecasts for Benton, Franklin, and Yakima Counties. These forecasts will be used in the socioeconomic analysis portion of the New Production Reactor Environmental Impact Statement. Aggregate population figures for the three counties in the study area were developed for high- and low-growth scenarios for the study period 1990 through 2040. Age-sex distributions for the three counties during the study period are also presented. The high and low scenarios were developed using high and low employment projections for the Hanford site. Hanford site employment figures were used as input for the HARC-REMI Economic and Demographic (HED) model to produced baseline employment forecasts for the three counties. These results, in turn, provided input to an integrated three-county demographic model. This model, a fairly standard cohort-component model, formalizes the relationship between employment and migration by using migration to equilibrate differences in labor supply and demand. In the resulting population estimates, age-sex distributions for 1981 show the relatively large work force age groups in Benton County while Yakima County reflects higher proportions of the population in the retirement ages. The 2040 forecasts for all three counties reflect the age effects of relatively constant and low fertility increased longevity, as well as the cumulative effects of the migration assumptions in the model. By 2040 the baby boom population will be 75 years and older, contributing to the higher proportion of population in the upper end age group. The low scenario age composition effects are similar. 13 refs., 5 figs., 9 tabs.

A social demographic study of the likelihood of sustaining an occupational fatality resulting in death  

E-Print Network (OSTI)

This thesis explores occupational fatalities to American males for the years 1998 and 1999. The focus is on predicting the likelihood that the individual will sustain an occupational injury resulting in death based on an occupational status score. Demographic variables measuring Southern residence, race, ethnicity, marital status, education and age were also included in analyses. Research questions include whether or not individuals in higher status occupations are at a decreased risk of sustaining an occupational fatality, and how the demographic variables included effect occupational fatalities. Using data from death certificates allowed me to measure the individual’s occupational status based on their “usual occupation” and find out whether or not differences exist. The thesis involves two analyses, one with the sample comprised of only males between the ages of 25 and 55 and one including only married males between the ages of 25 and 55. Logistic regression is employed as the method of analysis to model the odds of the risk of sustaining an occupational fatality that results in death. The results of the first model found only marital status to be positively and significantly related to occupational fatalities. Black, Hispanic, South and education were found to be negatively related to occupational fatalities. The main hypothesis of this thesis was not supported, however because the regression shows that with each increase on the occupational status index, no significant increase or decrease occurred in sustaining an occupational injury that resulted in death. In the second regression that included only married males, many of the relationships no longer existed. Hispanic and the education variable both lost statistical significance. The only variables to maintain significance were black and South, which were both associated with a decreased risk of sustaining an occupational injury that resulted in death. Problems with the occupational status index as a predictor for the likelihood of sustaining an occupational fatality and restrictions of the data may be the main issue that resulted in a lack of findings.

Trends in Utility Green Pricing Programs (2006)  

SciTech Connect

In the early 1990s, only a handful of utilities offered their customers a choice of purchasing electricity generated from renewable energy sources. Today, more than 750 utilities--or about 25% of all utilities nationally--provide their customers a "green power" option. Through these programs, more than 70 million customers have the ability to purchase renewable energy to meet some portion or all of their electricity needs--or make contributions to support the development of renewable energy resources. Typically, customers pay a premium above standard electricity rates for this service. This report presents year-end 2006 data on utility green pricing programs, and examines trends in consumer response and program implementation over time. The data in this report, which were obtained via a questionnaire distributed to utility green pricing program managers, can be used by utilities to benchmark the success of their green power programs.

Solar markets are booming in the United States due to rising energy prices, strong consumer demand, and financial incentives from the federal government, states and utilities. Over 62,000 new solar thermal and solar electric installations were completed in 2008, an increase of 16 % compared with 2007. The majority of market share for each solar technology is concentrated in a few states. Photovoltaic trends: • The capacity of photovoltaic (PV) installations completed in 2008 grew by 63 % compared with installations in 2007, and the average size of PV systems is increasing. • Installation growth by capacity was largest in the nonresidential sector, but the residential sector continues to dominate the number of installations. • Many states reported a doubling of PV capacity installed in

EIA - Annual Energy Outlook 2008 (Early Release)- Energy Trends to 2030  

Gasoline and Diesel Fuel Update (EIA)

Trends to 2030 Trends to 2030 Annual Energy Outlook 2008 (Early Release) Energy Trends to 2030 In preparing projections for the Annual Energy Outlook 2008 (AEO2008), the Energy Information Administration (EIA) evaluated a wide range of trends and issues that could have major implications for U.S. energy markets between today and 2030.1 This overview focuses on one case, the reference case, which is presented and compared with the Annual Energy Outlook 2007 (AEO2007) reference case (see Table 1). Readers are encouraged to review the full range of alternative cases included in other sections of AEO2008. As in previous editions of the Annual Energy Outlook (AEO), the reference case assumes that current policies affecting the energy sector remain unchanged throughout the projection period. Some possible policy changes—notably, the adoption of policies to limit or reduce greenhouse gas emissions—could change the reference case projections significantly.2 EIA has examined many of the proposed greenhouse gas policies at the request of Congress; the reports are available on EIA’s web site.3

Trends in U.S. Residential Natural Gas Consumption  

Gasoline and Diesel Fuel Update (EIA)

Trends in U.S. Residential Natural Gas Consumption Trends in U.S. Residential Natural Gas Consumption This report presents an analysis of residential natural gas consumption trends in the United States through 2009 and analyzes consumption trends for the United States as a whole (1990 through 2009) and for each Census Division (1998 through 2009). It examines a long-term downward per- customer consumption trend and analyzes whether this trend persists across Census Divisions. The report also examines some of the factors that have contributed to the decline in per-customer consumption. To provide a more meaningful measure of per-customer consumption, EIA adjusted consumption data presented in the report for weather.

Counter Current Multiplier Mechanism  

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

Counter Current Multiplier Mechanism Counter Current Multiplier Mechanism Name: Stephen Location: N/A Country: N/A Date: N/A Question: Can you please explain to me the counter-current multiplier mechanism. I understand that cholride and sodium ions are filtered out of the ascending loop of Henle into the interstial fluid, however, I'm not sure exactly what happens from there and how this effects osmotic pressure gradients in the nephron. Any help would be greatly appriciated. Replies: This mechanism is very complex when it comes to writing a response. You have to have a strong background in osmotic pressure understanding and the anatomy of the kidney. It involves the cortex, outer and inner medula in relationship to the vasa recta, interstitial fluids at two points, the loop of Henle and the collecting duct. The size of the tubes and the position in relations to the cortex and medulla is an essential part. I can suggest some references.

Trends in the use of postoperative radiotherapy for resected non-small-cell lung cancer  

SciTech Connect

Purpose: A 1998 meta-analysis of postoperative radiotherapy (PORT) for non-small-cell lung cancer (NSCLC) found that PORT did not improve outcomes. Yet practice guidelines differ in their recommendations with regard to PORT use. We examine temporal trends in PORT use before and after the 1998 meta-analysis. Methods and Materials: Using data from the Surveillance, Epidemiology, and End Results (SEER) Program, we identified 22,953 patients with Stage I, II, or IIIA NSCLC who had resection between 1992 and 2002 in the United States and characterized each patient according to nodal status (N0, N1, or N2 disease). We measured use of PORT by calendar year. We examined the association between clinical and demographic characteristics and receipt of PORT using logistic regression. Results: For N0, N1, and N2 NSCLC, PORT use has declined. The proportion of patients with N0 disease receiving PORT declined from 8% in 1992 to 4% in 2002. For patients with N1 disease, PORT use declined from 51% in 1992 to 19% in 2002; and for patients with N2 disease, PORT use declined from 65% in 1992 to 37% in 2002. Conclusion: In the context of uncertainty about what constitutes optimal adjuvant treatment for resected NSCLC, PORT use has substantially declined.

Labor market trends for nuclear engineers through 2000  

SciTech Connect

Throughout most of the 1980s, both private organizations and government agencies were concerned about the availability of an adequate supply of qualified nuclear engineers. This concern was primarily the result of a number of nuclear engineering academic programs being eliminated coupled with a continuous decline in graduate and undergraduate enrollments and degrees. By the early 1990s, the number of degrees and available supply had declined to new lows, but cutbacks in funding for the nuclear weapons program and nuclear energy R&D, and in hiring by the electric utility industry, offset in large measure the declining supply. Recently, concerns about environment and waste management and about nuclear safety have again generated questions about the adequacy of supply of qualified personnel for nuclear energy activities. This report briefly examines the nuclear engineering labor market. Trends in employment, new graduates, job openings, and salaries are reviewed as a basis for understanding the current labor market. This review is then used as a basis for assessing future employment needs and new graduate supply to provide an outlook for future labor market conditions through 2000.

Trends and outlook for biomass energy  

Science Conference Proceedings (OSTI)

Among renewable energy resources, biomass is one of the most promising, with the potential for providing electricity through combustion, gasification, and biochemical processes as well as supplying gaseous and liquid fuels that can compete with conventional energy sources in large-scale applications. The production of biomass for energy purposes can also offer environmental benefits. The most notable is the potential for providing energy with little or no net buildup of carbon dioxide in the atmosphere if the biomass is produced renewably. Biomass also has the potential to help revitalize the rural sector of the economy. A domestic natural resource, biomass can be grown and harvested, which requires labor. The biomass power industry can therefore create jobs in harvesting and transporting biomass and in the related industries of fertilizers, pesticides, and agricultural equipment. In the future, biomass facilities will be larger and more efficient and, as such, an important alternative for energy generators. This article summarizes the factors relating to the use of biomass as a fuel source, the technology options for power generation, and examines the trends and outlook for biomass energy generation in the United States.

Retrospective Evaluation of Appliance Price Trends  

SciTech Connect

Real prices of major appliances (refrigerators, dishwashers, heating and cooling equipment) have been falling since the late 1970s despite increases in appliance efficiency and other quality variables. This paper demonstrates that historic increases in efficiency over time, including those resulting from minimum efficiency standards, incur smaller price increases than were expected by Department of Energy (DOE) forecasts made in conjunction with standards. This effect can be explained by technological innovation, which lowers the cost of efficiency, and by market changes contributing to lower markups and economies of scale in production of higher efficiency units. We reach four principal conclusions about appliance trends and retail price setting: 1. For the past several decades, the retail price of appliances has been steadily falling while efficiency has been increasing. 2. Past retail price predictions made by DOE analyses of efficiency standards, assuming constant prices over time, have tended to overestimate retail prices. 3. The average incremental price to increase appliance efficiency has declined over time. DOE technical support documents have typically overestimated this incremental price and retail prices. 4. Changes in retail markups and economies of scale in production of more efficient appliances may have contributed to declines in prices of efficient appliances.

Trends in Utility Green Pricing Programs (2004)  

Science Conference Proceedings (OSTI)

In the early 1990s, only a handful of utilities offered their customers a choice of purchasing electricity generated from renewable energy sources. Today, nearly 600 utilities in regulated electricity markets--or almost 20% of all utilities nationally--provide their customers a "green power" option. Because some utilities offer programs in conjunction with cooperative associations or other publicly owned power entities, the number of distinct programs totals about 125. Through these programs, more than 40 million customers spanning 34 states have the ability to purchase renewable energy to meet some portion or all of their electricity needs--or make contributions to support the development of renewable energy resources. Typically, customers pay a premium above standard electricity rates for this service. This report presents year-end 2004 data on utility green pricing programs, and examines trends in consumer response and program implementation over time. The data in this report, which were obtained via a questionnaire distributed to utility green pricing program managers, can be used by utilities as benchmarks by which to gauge the success of their green power programs.

Maritime Transportation System: Trends and Outlook  

E-Print Network (OSTI)

2007-R-5 Water is an essential resource in the U.S. economy. It plays a crucial role in supporting many economic activities and ensuring the quality of human life and the health of ecological systems. Despite this, the value of water may not be widely appreciated because only some water resources and water uses are easily visible or noticed while others are not. Among the Institute for Water Resources (IWR) Future Directions program activities are the identification of emerging water challenges and opportunities and the tactical engagement of U.S. Army Corps of Engineers (USACE) senior leaders on these issues. Such critical thinking is an essential prerequisite to strategy development and planning. IWR has developed this series of Water Resources Outlook papers, commissioned utilizing outside experts, to identify emerging issues and implications for the Nation. These issues and implications will be presented in the form of “provocation sessions ” with external and internal subject matter experts and stakeholders and will inform the USACE strategic planning process.

Contracting Polymer with Current  

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

Contracting Polymer with Current Contracting Polymer with Current Name: Ian Status: student Grade: 9-12 Location: PA Country: USA Date: Summer 2011 Question: Hello and thank you in advance. I have previously read of a material ( a kind of "rubber") that contracts when an electric current is applied. My question is what is this material, how does it work/what is it made of? Thank you very much. Replies: Hi Ian, I believe the material you are referring to is a kind of piezoelectric rubber. Piezoelectric materials (usually they are special types of ceramics or crystals) produce an electrical voltage when compressed of otherwise subjected to stress. They also do the opposite... they slightly expand or contract when a voltage is applied. But the amount they expand or contract is very small indeed. For example, one square meter of the recently discovered piezoelectric rubber materials typically contracts a mere 100 picometers for ever applied volt. Translated into everyday measurements, this means that if you apply a voltage of 1 Volt to a one foot long piece of this rubber, it will only contract less than half a billionth of an inch! Applying 100 volts will cause it to contract just under 50 billionths of an inch!

1999 Commercial Buildings Characteristics--Trends in Commercial Buildings  

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

Trends in Commercial Buildings and Floorspace Trends in Commercial Buildings and Floorspace Trends in Commercial Buildings and Floorspace The addition of commercial buildings and floorspace from 1995 to 1999 continued the general trends noted since 1979 (Figures 1 and 2). The size of the commercial buildings has grown steadily over the twenty years of CBECS. Each year more buildings are added to the sector (new construction or conversion of pre-existing buildings to commercial activity) than are removed (demolition or conversion to non-commercial activity). The definition for the commercial buildings population was changed for the 1995 CBECS which resulted in a slightly smaller buildings population and accounts for the data break in both Figures 1 and 2 (see report "Trends in the Commercial Buildings Sector" for complete details).

Trends in the size distribution, highway use, and consumption of gasoline and diesel fuels of the U.S. Commercial Truck Fleet, 1977-2002.  

SciTech Connect

This paper focuses on various major long-range (1977-2002, 1982-2002) U.S. commercial trucking trends by using U.S. Department of Commerce, Bureau of the Census Vehicle/Truck Inventory and Use Survey (VIUS/TIUS) data from this period, as well as selected 1977-2002 data from the U.S. Department of Energy's (DOE's) Energy Information Administration (EIA) and the U.S. Department of Transportation, Federal Highway Administration's (FHWA's) Highway Statistics. Analyses are made of (1) overall passenger vehicle versus truck consumption patterns of gasoline and diesel fuel and (2) the population growth and fuels used by all commercial truck classes and selected truck types (single unit and combination). Selected vehicle miles traveled, gallons per vehicle miles traveled, and gallons per cargo ton-miles traveled trends, as well as the effect of cargo tons per truck on fuel consumption, are also assessed. In addition, long-range trends of related factors (such as long-haul mileages driven by heavy trucks) and their impacts on both reducing fuel consumption per cargo-ton-mile and the relative shares of total commercial fuel use among truck classes were examined. Results of these trends on U.S. petroleum consumption are identified. The effects of basic engineering design and performance, national Interstate highway construction legislation, national demographic trends (such as suburbanization), and changes in U.S. corporate operational requirements are discussed. Their impacts on both the long-distance hauling and shorter-distance urban and suburban delivery markets of the commercial trucking industry are highlighted.

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

SciTech Connect

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

RECENT TRENDS IN EMERGING TRANSPORTATION FUELS AND ENERGY CONSUMPTION  

Science Conference Proceedings (OSTI)

Abundance of energy can be improved both by developing new sources of fuel and by improving efficiency of energy utilization, although we really need to pursue both paths to improve energy accessibility in the future. Currently, 2.7 billion people or 38% of the world s population do not have access to modern cooking fuel and depend on wood or dung and 1.4 billion people or 20% do not have access to electricity. It is estimated that correcting these deficiencies will require an investment of $36 billion dollars annually through 2030. In growing economies, energy use and economic growth are strongly linked, but energy use generally grows at a lower rate due to increased access to modern fuels and adaptation of modern, more efficient technology. Reducing environmental impacts of increased energy consumption such as global warming or regional emissions will require improved technology, renewable fuels, and CO2 reuse or sequestration. The increase in energy utilization will probably result in increased transportation fuel diversity as fuels are shaped by availability of local resources, world trade, and governmental, environmental, and economic policies. The purpose of this paper is to outline some of the recently emerging trends, but not to suggest winners. This paper will focus on liquid transportation fuels, which provide the highest energy density and best match with existing vehicles and infrastructure. Data is taken from a variety of US, European, and other sources without an attempt to normalize or combine the various data sources. Liquid transportation fuels can be derived from conventional hydrocarbon resources (crude oil), unconventional hydrocarbon resources (oil sands or oil shale), and biological feedstocks through a variety of biochemical or thermo chemical processes, or by converting natural gas or coal to liquids.

Labor market trends for nuclear engineers through 2005  

SciTech Connect

Between 1983 and 1989, employment of nuclear engineers in the nuclear energy field increased almost 40 percent while the annual number of nuclear engineering degrees awarded decreased by almost one-fourth. There were, on average, more job openings for new graduates than there were new graduates available to fill the jobs during the 1980s. This trend reversed in the l990s as nuclear engineering employment in the nuclear energy field decreased from 11,500 in 1991 to 9,400 in 1995. During roughly the same period, the annual number of nuclear engineering degrees increased by 11 percent. As a result, from 1990 through 1995, the number of new graduate nuclear engineers available in the labor supply far exceeded the number of job openings for new graduates in the nuclear energy field. This oversupply of new graduates was particularly acute for 1993 through 1995. During 1996--1997, a relative improvement is expected in job opportunities in the nuclear energy field for new graduates; however, a large oversupply is still expected (almost twice as many graduates available for employment as there are job openings). For 1998 through 2000, some improvement is expected in the relative number of job opportunities for new graduates in the nuclear energy field. Nuclear engineering jobs in the nuclear energy field are expected to decrease only slightly (by less than 150) during this period. Also a 10--15% decrease in the annual number of degrees and available supply of new graduates is expected. Overall, an oversupply is expected (140 graduates available per 100 job openings for new graduates in the nuclear energy field), but this is still a substantial improvement over the current period. For 2001 through 2005, if enrollments and degrees continue to decline, the labor market for new graduates is expected to be approximately balanced. This assumes, however, that the number of degrees and the available supply of new graduates will decrease by 25% from 1995 levels.

Stochastic modeling and global warming trend extraction for ocean acoustic travel times. Interim technical report  

SciTech Connect

A possible indication of the existence of global climate warming is a negative trend for the travel time of an acoustic pulse along a fixed long path, or paths, in the ocean over a period of many years. The goal of this report is the development of methods specifically for determining the presence of a long term trend for climate change from a temporal sequence of measurements of acoustic propagation times. Robust statistical methods for determining whether a significant trend is present in a given set of time series data have been developed and, for illustration, applied to some specific traveltime time series generated by the MASIG and GFDL ocean models. In this report we consider line + noise and ARIMA statistical models. We show that if the time series are long enough, somewhat over 20 years, then series such as those simulated by the MASIG and GFDL models can be classified reliably as line + noise when this is the case. However, it is shown that the results are considerably different for the two ocean models under consideration and that these models can not currently be relied upon by themselves to predict global warming. Experimental data is most certainly needed, not only to measure global warming itself, but to help improve the ocean model themselves.

NONDESTRUCTIVE EDDY CURRENT TESTING  

DOE Patents (OSTI)

An eddy current testing device is described for measuring metal continuity independent of probe-to-sample spacing. An inductance would test probe is made a leg of a variable impedance bridge and the bridge is balanced with the probe away from the sample. An a-c signal is applied across the input terminals of the bridge circuit. As the probe is brought into proximity with the metal sample, the resulting impedance change in the probe gives an output signal from the bridge whose phase angle is proportional to the sample continuity and amplitude is proportional to the probe-tosample spacing. The output signal from the bridge is applied to a compensating network where, responsive to amplitude changes from the bridge output signal, a constant phased voltage output is maintained when the sample is continuous regardless of probe-to-sample spacing. A phase meter calibrated to read changes in resistivity of the metal sample measures the phase shift between the output of the compensating network and the original a-c signal applied to the bridge.

Circulating current battery heater  

SciTech Connect

A circuit for heating energy storage devices such as batteries is provided. The circuit includes a pair of switches connected in a half-bridge configuration. Unidirectional current conduction devices are connected in parallel with each switch. A series resonant element for storing energy is connected from the energy storage device to the pair of switches. An energy storage device for intermediate storage of energy is connected in a loop with the series resonant element and one of the switches. The energy storage device which is being heated is connected in a loop with the series resonant element and the other switch. Energy from the heated energy storage device is transferred to the switched network and then recirculated back to the battery. The flow of energy through the battery causes internal power dissipation due to electrical to chemical conversion inefficiencies. The dissipated power causes the internal temperature of the battery to increase. Higher internal temperatures expand the cold temperature operating range and energy capacity utilization of the battery. As disclosed, either fixed frequency or variable frequency modulation schemes may be used to control the network.

Eddy current transducing system  

SciTech Connect

In a program funded by the Office of Energy Related Inventions of the Department of Energy, Vatell Corporation developed a prototype Turbine Blade Condition Monitor. This microcomputer-based system was tested to determine its performance in measuring individual blade clearance and time of arrival on a Pratt Whitney (Canada) JT15D jet engine. A Vatell eddy-current sensor mounted in the housing of the engine at mid-chord of the N1 first stage provided the signals. The N1 first stage is a 31 in. diameter fan with 28 titanium blades, operating over a speed range of approximately 7000 to 14,000 rpm. Tests showed that the monitoring system transduced blade clearances with a precision of .0001 in., simultaneously indicating times of arrival within 0.1 microseconds, equivalent to a pitch of .0015 in. Patterns of blade clearances and timing variations were observed for various engine operating conditions, and the clearance and time of arrival signatures'' of the fan stage were recorded. Manufacturing variations in blade pitch were readily detected, as were indications of blade and hub vibration. The report contains a detailed description of the development program, examples of waveforms and recorded data, circuit diagrams, software, setup and operating procedures for the monitoring system. 66 refs.

Home > Trends in Commercial Buildings > Home > Trends in Commercial Buildings > Trends in Buildings Floorspace Data tables Commercial Buildings Trend—Detail Commercial Floorspace Trend—Detail Background: Adjustment to data Trends in Buildings and Floorspace Each year buildings are added to and removed from the commercial buildings sector. Buildings are added by new construction or conversion of existing buildings from noncommercial to commercial activity. Buildings are removed by demolition or conversion from commercial to noncommercial activity. Number of Commercial Buildings In 1979, the Nonresidential Buildings Energy Consumption Survey estimated that there were 3.8 million commercial buildings in the United States; by 1992, the number increased 27 percent to 4.8 million (an average annual increase of 1.8%) (Figure 1). In 1995, the estimated number declined to 4.6 million buildings, but it is unlikely that there was an actual decline in the number of buildings. To understand the apparent decline, two factors should be considered—the change in the way that the target population of commercial buildings was defined in 1995 and the uncertainty of estimates from sample surveys:

Temporal trend analysis of RCRA groundwater monitoring data  

SciTech Connect

Statistical analysis of RCRA groundwater monitoring data at a uranium hexafluoride processing facility showed a statistically significant increase in the concentration of gross beta activity in monitor wells downgradient of surface impounds storing calcium fluoride sludge and high pH water. Because evidence of leakage had not been detected in lysimeters installed beneath the impounds, the operator sought an evaluation of other potential causes of the result, including natural variability. This study determined that all five data sets showed either long-term excursionary (spike-like), or seasonal forms of temporal variation. Gross beta had an upward long-term trend with multiple excursions that almost appeared to be seasonal. Gross alpha had an upward long-term trend with multiple excursions that were clearly not seasonal. Specific conductance had both upward and downward long-term trends but no other variations. pH had a downward long-term trend with multiple excursions that were clearly not seasonal. Fluoride had a downward long-term trend without excursions but with clear seasonal variations. The gross beta result that appeared to be a significant change was a spike event on the upward long-term trend.

Stray current interference control for HVDC earth currents  

SciTech Connect

High-voltage direct current (HVDC) transmission lines exist around the world, with several in the US. When one conductor must be taken out of operation (in case of emergency), the earth may be used as an alternate conductor. The earth current may be accumulated on and discharged from underground metallic structures that cross the voltage gradient created by the current. Test results on two lines showed that stray current interference is not a major problem if mitigated properly.

Using vector magnetograms obtained with the Spectro-polarimeter (SP) on aboard Hinode satellite, we studied two helicity parameters (local twist and current helicity) of 64 active regions occurred in the descending phase of solar cycle 23 and the ascending phase of solar cycle 24. Our analysis gives the following results. (1) The 34 active regions of the solar cycle 24 follow the so-called hemispheric helicity rule, whereas the 30 active regions of the solar cycle 23 do not. (2) When combining all 64 active regions as one sample, they follow the hemispheric helicity sign rule as in most other observations. (3) Despite with the so-far most accurate measurement of vector magnetic field given by SP/Hinode, the rule is still weak with large scatters.

Gas-fired cooling status and trends  

SciTech Connect

The current US heating, ventilating, and air-conditioning (HVAC) market shows that the predictions of a health expansion in this market are attainable in this decade. The HVAC industry`s positive trade balance is widening; their successful hedge against various economic problems (the lack of financial and personnel resources) and their initiative to overcome the technical obstacles (caused by environmental issues) will have a positive, long-term impact. This along with energy availability and a favorable price structure has created a unique opportunity for the gas industry to regain and surpass previous respectable market shares attained with gas cooling technologies. New first generation gas cooling equipment is now entering the US marketplace with bold market predictions for commercial chillers and roof-top units, as well as for residential equipment. The marketing campaign covers a broad base of technical and supporting elements. It is the continued research, education, and training of engineers, architects, dealers, and utility sales personnel that can break the existing and serious barriers to the successful marketing of these cooling equipment products. Research in lowering equipment costs, personnel training, more units in the field, and more utility support in commercialization and deployment activities will guarantee an expansion of the market for the gas industry.

(5) With two example sunspots we show that the helicity parameters change sign from the inner umbra to the outer penumbra, where the sign of penumbra agrees with the sign of the active region as a whole. From these results, we speculate that both the {Sigma}-effect (turbulent convection) and the dynamo have contributed in the generation of helicity, whereas in both cases turbulence in the convection zone has played a significant role.

PREFERRED WATERFLOOD MANAGEMENT PRACTICES FOR THE SPRABERRY TREND AREA  

SciTech Connect

The naturally fractured Spraberry Trend Area is one of the largest reservoirs in the domestic U.S. and is the largest reservoir in area extent in the world. Production from Spraberry sands is found over a 2,500 sq. mile area and Spraberry reservoirs can be found in an eight county area in west Texas. Over 150 operators produce 65,000 barrels of oil per day (bopd) from the Spraberry Trend Area from more than 9,000 production wells. Recovery is poor, on the order of 7-10% due to the profoundly complicated nature of the reservoir, yet billions of barrels of hydrocarbons remain. We estimate over 15% of remaining reserves in domestic Class III reservoirs are in Spraberry Trend Area reservoirs. This tremendous domestic asset is a prime example of an endangered hydrocarbon resource in need of immediate technological advancements before thousands of wells are permanently abandoned. This report describes the final work of the project, ''Preferred Waterflood Management Practices for the Spraberry Trend Area.'' The objective of this project is to significantly increase field-wide production in the Spraberry Trend in a short time frame through the application of preferred practices for managing and optimizing water injection. Our goal is to dispel negative attitudes and lack of confidence in water injection and to document the methodology and results for public dissemination to motivate waterflood expansion in the Spraberry Trend. This objective has been accomplished through research in three areas: (1) detail historical review and extensive reservoir characterization, (2) production data management, and (3) field demonstration. This provides results of the final year of the three-year project for each of the three areas.

Ionization tube simmer current circuit  

DOE Patents (OSTI)

A highly efficient flash lamp simmer current circuit utilizes a fifty percent duty cycle square wave pulse generator to pass a current over a current limiting inductor to a full wave rectifier. The DC output of the rectifier is then passed over a voltage smoothing capacitor through a reverse current blocking diode to a flash lamp tube to sustain ionization in the tube between discharges via a small simmer current. An alternate embodiment of the circuit combines the pulse generator and inductor in the form of an FET off line square wave generator with an impedance limited step up output transformer which is then applied to the full wave rectifier as before to yield a similar simmer current.

A Population Study of Golden Eagles in the Altamont Pass Wind Resource Area: Population Trend Analysis, 1994-1997  

SciTech Connect

The wind industry has annually reported 28-43 turbine blade strike casualties of golden eagles in the Altamont Pass Wind Resource Area, and many more carcasses have doubtless gone unnoticed. Because this species is especially sensitive to adult survival rate changes, we focused upon estimating the demographic trend of the population. In aerial surveys, we monitored survival within a sample of 179 radio-tagged eagles over a four-year period. We also obtained data on territory occupancy and reproduction of about 65 eagle pairs residing in the area. Of 61 recorded deaths of radio-tagged eagles during the four-year investigation, 23 (38%) were caused by wind turbine blade strikes. Additional fatalities were unrecorded because blade strikes sometimes destroy radio transmitters. Annual survival was estimated at 0.7867 (SE=0.0263) for non-territorial eagles and 0.8964 (SE=0.0371) for territorial ones. Annual reproduction was 0.64 (SE=0.08) young per territorial pair (0.25 per female). These parameters were used to estimate population growth rates under different modeling frameworks. At present, there are indications that a reserve of non-breeding adults still exists, i.e., there is an annual territorial reoccupancy rate of 100% and a low incidence (3%) of subadults as members of breeding pairs.

Improving dual-porosity simulation of waterflood performance in the naturally fractured Spraberry Trend area  

E-Print Network (OSTI)

In this thesis we have discussed the methods of analyzing the waterflood performance of the O'Daniel waterflood pilot in the Spraberry Trend Area with the help of reservoir simulation. Spraberry Trend Area is considered to be one of the richest oil fields in the world. However, out of 6-10 billion bbls of original oil only 700 million bbls have been produced. In an effort to increase recovery, several waterflood pilots were conducted in Spraberry beginning in the late 1950's. Because of profoundly complicated nature of the reservoir, waterflooding has been only moderately successful, and billions of barrels of hydrocarbons remain unrecovered. A recent waterflood pilot study started in 1995 with dramatically different results. The pilot was conducted in the O'Daniel unit of the Spraberry. The recovery in this lease has exceeded 25% of the original oil in place, compared to only 10% recovery in the entire Spraberry. Data from the current waterflood clearly shows that on-trend wells which are outside the pilot and along the major fracture trend responded favorably. In the previous waterflood pilots in Spraberry, the producer located off-trend from the water injectors received all the attention and the response in the on-trend wells was overlooked. In this study, we have developed a waterflood pattern for Spraberry where the target wells for waterflood response will be the on-trend producers. A successful waterflood depends on properly positioning the injectors and producers. In fractured reservoirs, fracture location, orientation and permeability dictates the placing of injection and production wells. So, to understand the fracture distribution, the main intention behind this thesis is to develop a method to determine location, orientation and permeability of fractures in Spraberry by using reservoir simulation. We performed three simulation studies: Humble pilot waterflood, O'Daniel tracer analysis and O'Daniel pilot waterflood. The first two simulation studies were performed with simple two-well models. The fracture orientation and permeability ratio obtained in these models were applied to the full field O'Daniel pilot that consists of 59 wells in about 8500-acre area. Our simulation model shows that a concept of fracture enhancement (grid-blocks with high fracture permeability) in the dual-porosity model is necessary to capture the effect of heterogeneity of fracture network. The major fracture orientation obtained from the simulation is very close to the one obtained from the interference test and horizontal core analysis. The results of this study could be used in determining an optimum waterflood pattern suitable for that area to forecast oil production with different scenarios such as, infill drilling, CO2 injection, horizontal wells etc. Finally, the results of this work will provide a method to assess the economic feasibility of large-scale water injection in the remainder of the field.

Trends in U.S. oil prices, energy consumption, and economic output, 1950-2035 Click to enlarge » Figure source and data excel logo Energy intensity trends in AEO2010 Energy intensity—energy consumption per dollar of real GDP—indicates how much energy a country uses to produce its goods and services. From the early 1950s to the early 1970s, U.S. total primary energy consumption and real GDP increased at nearly the same annual rate (Figure 17). During that period, real oil prices remained virtually flat. In contrast, from the mid-1970s to 2008, the relationship between energy consumption and real GDP growth changed, with primary energy consumption growing at less than one-third the previous average rate and real GDP growth continuing to grow at its historical rate. The decoupling of real GDP growth from energy consumption growth led to a decline in energy intensity that averaged 2.8 percent per year from 1973 to 2008. In the AEO2010 Reference case, energy intensity continues to decline, at an average annual rate of 1.9 percent from 2008 to 2035.

Current Drive in Recombining Plasma  

SciTech Connect

The Langevin equations describing the average collisional dynamics of suprathermal particles in nonstationary plasma remarkably admit an exact analytical solution in the case of recombining plasma. The current density produced by arbitrary particle fluxes is derived including the effect of charge recombination. Since recombination has the effect of lowering the charge density of the plasma, thus reducing the charged particle collisional frequencies, the evolution of the current density can be modified substantially compared to plasma with fixed charge density. The current drive efficiency is derived and optimized for discrete and continuous pulses of current, leading to the discovery of a nonzero "residual" current density that persists indefinitely under certain conditions, a feature not present in stationary plasmas.

A voltage controlled current source  

DOE Patents (OSTI)

A seven decade, voltage controlled current source is described for use in testing intermediate range nuclear instruments that covers the entire test current range of from 10 picoampers to 100 microamperes. High accuracy is obtained throughout the entire seven decades of output current with circuitry that includes a coordinated switching scheme responsive to the input signal from a hybrid computer to control the input voltage to an antilog amplifier, and to selectively connect a resistance to the antilog amplifier output to provide a continuous output current source as a function of a preset range of input voltage. An operator controlled switch provides current adjustment for operation in either a real-time simulation test mode or a time response test mode.

METHOD OF PEAK CURRENT MEASUREMENT  

DOE Patents (OSTI)

The measurement and recording of peak electrical currents are described, and a method for utilizing the magnetic field of the current to erase a portion of an alternating constant frequency and amplitude signal from a magnetic mediums such as a magnetic tapes is presented. A portion of the flux from the current carrying conductor is concentrated into a magnetic path of defined area on the tape. After the current has been recorded, the tape is played back. The amplitude of the signal from the portion of the tape immediately adjacent the defined flux area and the amplitude of the signal from the portion of the tape within the area are compared with the amplitude of the signal from an unerased portion of the tape to determine the percentage of signal erasure, and thereby obtain the peak value of currents flowing in the conductor.

Water Quality Trends in the Entiat River Subbasin: Final 2008 Annual Report.  

DOE Green Energy (OSTI)

The ISEMP program monitors the status and trend of water quality elements that may affect restoration project effectiveness in the Entiat subbasin. As part of this effort, the PNW Research Station (PNW) measures, analyzes and interprets temporal trends in natural stream water pH, dissolved oxygen, specific conductivity and temperature. The Entiat River is currently on the Clean Water Act 303(d) list for pH exceedence, and there is insufficient information to determine the spatial and temporal extent or potential causes of this exceedence. In the spring 2008, PNW redeployed data-logging, multiparameter probes at four locations in the Entiat subbasin to measure water quality parameters, focusing on pH. This resumed previous data collection that was interrupted by river ice in early December 2007. Instruments were again removed from the river in early December 2008. This annual report covers the period from December 2007 through December 2008. The highest pH values occurred during the low-flow period from midsummer through the following midspring then dropped sharply during the annual snowmelt runoff period from late spring through early summer. Water temperature began rapidly increasing during the receding limb of the annual snowmelt hydrograph. Highest mean monthly temperatures occurred in July and August, while instantaneous maxima occurred during the period July-September. Dissolved oxygen reached its lowest levels during the period of highest water temperature in July-September. Specific conductivity remained very low at all sites throughout the year.

Passive fault current limiting device  

DOE Patents (OSTI)

A passive current limiting device and isolator is particularly adapted for use at high power levels for limiting excessive currents in a circuit in a fault condition such as an electrical short. The current limiting device comprises a magnetic core wound with two magnetically opposed, parallel connected coils of copper, a high temperature superconductor or other electrically conducting material, and a fault element connected in series with one of the coils. Under normal operating conditions, the magnetic flux density produced by the two coils cancel each other. Under a fault condition, the fault element is triggered to cause an imbalance in the magnetic flux density between the two coils which results in an increase in the impedance in the coils. While the fault element may be a separate current limiter, switch, fuse, bimetal strip or the like, it preferably is a superconductor current limiter conducting one-half of the current load compared to the same limiter wired to carry the total current of the circuit. The major voltage during a fault condition is in the coils wound on the common core in a preferred embodiment. 6 figs.

Historical trends in tank 241-SY-101 waste temperatures and levels  

Science Conference Proceedings (OSTI)

The gas release and fluctuating level of the waste in tank 241-SY-101 have prompted more detailed interest in its historical behavior, in hopes of achieving a better understanding of its current status. To examine the historical behavior, essentially all of the tank waste temperature and level data record has been retrieved, examined, and plotted in various ways. To aid in interpreting the data, the depth of the non-convective waste layer was estimated by using a least-squares Chebyshev approximation to the temperatures. This report documents the retrieval critical examination, and graphic presentation of 241-SY-101 temperature and waste level histories. The graphic presentations clearly indicate a tank cooling trend that has become precipitous since late 1991. The plots also clearly show the decreasing frequency of waste gas release events, increasing height of the non-convective layer, and larger level drops per event.

Petroleum 1996: Issues and Trends Petroleum 1996: Issues and Trends 49 The U.S. is heavily reliant on the world crude oil market, which has been subject to huge inter-annual volatility since 1973. Neither of these facts is likely to change. Domestic crude oil production declined over the past decade, while domestic crude oil demand increased. The difference was satisfied by increased crude oil imports. The United States' proved crude oil reserves declined more than 21 percent from 1985 to 1995. Its technically recoverable crude oil resources beyond proved reserves are estimated to be about 6 times more than the year-end 1995 proved reserves. However, excepting the Gulf of Mexico and the Alaskan offshore, many of the most promising oil-prone regions of the country are presently off-limits to exploration. Over the

Trends in Building Energy Usage in Texas State Agencies  

E-Print Network (OSTI)

In late 1983, a cost containment program was initiated out of the governor's office directed at the major state agencies. The Energy Management Group at Texas A&M University provided technical expertise in obtaining agency energy usage and cost figures for the fiscal years 1981 to 1983. While there is considerable diversity from agency to agency, the trend is toward dramatically higher energy cost per square foot for virtually all agencies. This alarming trend can be partially explained by rising unit costs for gas and electricity and a lack of incentives for conservation efforts due to the method of utility budget allocations. A building standard signed into law in 1976 could have reduced energy consumption, but was never enforced. Beginning in fiscal year 1986, universities will be allowed to comingle utility money with capital operating money so that conservation can really pay off for them.

Energy use and conservation trends, 1972--1986  

SciTech Connect

US trends in energy use and conservation since 1972 are analyzed in this report. That year represents the last year prior to significant energy price shocks. In 1986, an estimated 31.8 quads has been saved in the US compared with what consumption would have been if the energy use per dollar of GNP had continued on the same trend after 1972 as in the period 1960--1972. Actual US energy consumption in 1986 was 74.3 quads. It is clear that energy conservation is persistent and conservation investments continue to pay off even after initial energy price shocks have subsided. Separate analyses have been conducted for the major end-use sectors (residential, commercial, industrial, and transportation). Savings have been estimated in each sector, and the factors contributing to sectoral savings identified. 19 refs., 23 figs., 26 tabs.

LONG-TERM TRENDS IN SUNSPOT MAGNETIC FIELDS  

SciTech Connect

Recent studies indicate that a maximum field strength in sunspots shows a gradual decrease over the last several years. By extrapolating this trend, Penn and Livingston proposed that sunspots may completely disappear in the not-so-distant future. To verify these recent findings, we employ historic synoptic data sets from seven observatories in the former USSR covering the period from 1957 to 2011 (from 1998 to 2011, observations were taken at only one observatory). Our results indicate that while sunspot field strengths rise and wane with solar cycle, there is not a long-term trend that would suggest a gradual decrease in sunspot magnetic fields over the four and a half solar cycles covered by these observations.

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

Trends in On-Road Vehicle Emissions of Ammonia Trends in On-Road Vehicle Emissions of Ammonia Title Trends in On-Road Vehicle Emissions of Ammonia Publication Type Journal Article Year of Publication 2008 Authors Kean, Andrew J., David Littlejohn, George Ban-Weiss, Robert A. Harley, Thomas W. Kirchstetter, and Melissa M. Lunden Journal Atmospheric Environment Abstract Motor vehicle emissions of ammonia have been measured at a California highway tunnel in the San Francisco Bay area. Between 1999 and 2006, light-duty vehicle ammonia emissions decreased by 38 ± 6%, from 640 ± 40 to 400 ± 20 mg kg-1. High time resolution measurements of ammonia made in summer 2001 at the same location indicate a minimum in ammonia emissions correlated with slower-speed driving conditions. Variations in ammonia emission rates track changes in carbon monoxide more closely than changes in nitrogen oxides, especially during later evening hours when traffic speeds are highest. Analysis of remote sensing data of Burgard et al. (Environ Sci. Technol. 2006, 40, 7018-7022) indicates relationships between ammonia and vehicle model year, nitrogen oxides, and carbon monoxide. Ammonia emission rates from diesel trucks were difficult to measure in the tunnel setting due to the large contribution to ammonia concentrations in a mixed-traffic bore that were assigned to light-duty vehicle emissions. Nevertheless, it is clear that heavy-duty diesel trucks are a minor source of ammonia emissions compared to light-duty gasoline vehicles.

Analysis > Seasonality in the Natural Gas Balancing Item: Historical Trends and Corrective Measures Analysis > Seasonality in the Natural Gas Balancing Item: Historical Trends and Corrective Measures Seasonality in the Natural Gas Balancing Item: Historical Trends and Corrective Measures Released: June 4, 2010 Download Full Report (PDF) This special report examines an underlying cause of the seasonal pattern in the balancing item published in the Natural Gas Monthly. Research finds that a significant portion of data collected on EIAÂ’s primary monthly natural gas consumption survey reflects billing data that does not strictly coincide with the actual calendar month, which creates an aggregate-level discrepancy with EIAÂ’s other natural gas supply and disposition data series. This discrepancy is especially observable during the fall and spring as one transitions into and out of the winter heating season. The report also outlines improved data collection and estimation procedures that will be implemented later this year to more closely align reported and actual calendar month consumption. This discussion will be helpful to users of EIAÂ’s volumetric natural gas data. Questions about this report should be directed to Andy Hoegh at andrew.hoegh@eia.doe.gov or (202) 586-9502.

Trends in Information Management at Department of Energy Headquarters  

SciTech Connect

The Trends in Information Resource Management at DOE Headquarters (Trends) is published annually to inform the DOE Headquarters community about changes in the information management environment. The document, in its second year of publication, is becoming more robust as more historical data is available and as the information management environment at Headquarters evolves. One of the purposes of the Trends document is to acquire evidence that Headquarters organizations are assimilating guidance offered in the Emerging Technologies Planning Guide into their IRM strategies. Another purpose is to identify areas of interest and requirements of the Headquarters organizations to direct technology research for future issues of the Guide. These categories have been tentatively established as indicators of the degree of implementation of information management. The main source of data is the Headquarters Organization Plans, which were updated during the long-range update cycle conducted from August to January. Since these plans were published, the Secretary has announced a reorganization of DOE. For the purpose of this document, the information in the various plans is considered to be valid to accomplish the Departmental missions.
