DESIGN, FABRICATION, AND TESTING OF AN ADVANCED, NON-POLLUTING TURBINE DRIVE GAS GENERATOR (open access)

DESIGN, FABRICATION, AND TESTING OF AN ADVANCED, NON-POLLUTING TURBINE DRIVE GAS GENERATOR

The objective of this report period was to continue the development of the Gas Generator design, completion of the hardware and ancillary hardware fabrication and commence the Test Preparations for the testing of the non-polluting unique power turbine driven Gas Generator. Focus during this report period has been on completing the Gas Generator fabrication of hardware and ancillary hardware, and completion of unit closeout brazing and bonding. Because of unacceptable delays encountered in a previously competitively selected test site, CES initiated a re-competition of our testing program and selected an alternate test site. Following that selection, CES used all available resources to make preparations for testing the 10 Mw Gas Generator at the new testing site facilities of NTS at Saugus, CA.

Foreign Assistance: USAID Relies Heavily on Nongovernmental Organizations, but Better Data Needed to Evaluate Approaches

A letter report issued by the General Accounting Office with an abstract that begins "U.S. officials are interested in transferring some government social welfare functions to nongovernmental organizations (NGOs). One area is in the delivery of foreign assistance to developing countries and countries transitioning from communism to market-oriented democracy. Many NGOs active in international development have years of experience working overseas and have received millions of dollars in funds from private sources as well as the U.S. government. USAID directed $4 billion of its $7.2 billion assistance funding to NGOs in fiscal year 2000. However, the amount of funding provided by specific types of assistance is unknown, because USAID lacks comprehensive and reliable data. USAID uses various types of contracts, grants, and cooperative agreements to provide assistance through NGOs. This range of funding mechanisms allows USAID flexibility to draw on the strengths and expertise of a large community of experienced NGOs. The different mechanisms have advantages and disadvantages in terms of cost, time, selection of potential implementers, and USAID's authority to oversee assistance activities. Compared with USAID, official donors provide more of their funding to foreign governments and private donors and spend more of their funding on unsolicited proposals. USAID …

Fast-neutron-induced fission studied by gamma-spectroscopy. (open access)

Fast-neutron-induced fission studied by gamma-spectroscopy.

Prompt gamma-ray and x-ray spectroscopy techniques are being employed to study fast-neutron-induced fission of actinides to determine independent (pre-beta-decay) yields for a wide range of product nuclides. Data are acquired using the GEANIE high-resolution gamma-ray spectrometer at the LANSCE/WNR unmoderated spallation neutron source providing neutrons with energies from below 1 MeV to over 400 MeV. Three different techniques (identification by characteristic gamma rays, by gamma-gamma coincidences, and by fission-gamma coincidences) are being used to gather complementary data sets from which detailed fission yields can be extracted. From these data, mass and charge distributions are determined over a wide incident-neutron energy range. The phenomena of interest include the transition from asymmetric to symmetric fission, the competition between neutron and gamma-ray emission, nuclear structure effects in fission and the angular momentum imparted to the fission products. Results for 238U and 236U are presented.

California customer load reductions during the electricity crisis: Did they help to keep the lights on? (open access)

California customer load reductions during the electricity crisis: Did they help to keep the lights on?

During summer 2001, Californians reduced electricity usage by 6 percent and average monthly peak demand by 8 percent, compared to summer 2000. These load reductions played an important role in avoiding the hundreds of hours of rotating power outages predicted several months prior. Many factors affected electricity use and peak demand in summer 2001, including weather, changes in the State's economy, and deliberate consumer responses to a variety of stimuli associated with the crisis. This paper assesses the roles played by these contributing factors, with a special focus on the extraordinary efforts made by Californians to reduce electricity consumption. We review the role of media coverage and informational campaigns on public awareness and the impact of rate increases and a variety of publicly funded programs in reducing electricity consumption. We also draw lessons for other regions that may be faced with the prospect of electricity shortages.

The Theory of Random Laser Systems (open access)

The Theory of Random Laser Systems

Studies of random laser systems are a new direction with promising potential applications and theoretical interest. The research is based on the theories of localization and laser physics. So far, the research shows that there are random lasing modes inside the systems which is quite different from the common laser systems. From the properties of the random lasing modes, they can understand the phenomena observed in the experiments, such as multi-peak and anisotropic spectrum, lasing mode number saturation, mode competition and dynamic processes, etc. To summarize, this dissertation has contributed the following in the study of random laser systems: (1) by comparing the Lamb theory with the Letokhov theory, the general formulas of the threshold length or gain of random laser systems were obtained; (2) they pointed out the vital weakness of previous time-independent methods in random laser research; (3) a new model which includes the FDTD method and the semi-classical laser theory. The solutions of this model provided an explanation of the experimental results of multi-peak and anisotropic emission spectra, predicted the saturation of lasing modes number and the length of localized lasing modes; (4) theoretical (Lamb theory) and numerical (FDTD and transfer-matrix calculation) studies of the origin of …

Future of Inertial Fusion Energy (open access)

Future of Inertial Fusion Energy

In the past 50 years, fusion R&D programs have made enormous technical progress. Projected billion-dollar scale research facilities are designed to approach net energy production. In this century, scientific and engineering progress must continue until the economics of fusion power plants improves sufficiently to win large scale private funding in competition with fission and non-nuclear energy systems. This economic advantage must be sustained: trillion dollar investments will be required to build enough fusion power plants to generate ten percent of the world's energy. For Inertial Fusion Energy, multi-billion dollar driver costs must be reduced by up to an order of magnitude, to a small fraction of the total cost of the power plant. Major cost reductions could be achieved via substantial improvements in target performance-both higher gain and reduced ignition energy. Large target performance improvements may be feasible through a combination of design innovations, e.g., ''fast ignition,'' propagation down density gradients, and compression of fusion fuel with a combination of driver and chemical energy. The assumptions that limit projected performance of fusion targets should be carefully examined. The National Ignition Facility will enable development and testing of revolutionary targets designed to make possible economically competitive fusion power plants.

Central Asia Environmental Security Technical Workshop: Responding to the CENTCOM Vision (open access)

Central Asia Environmental Security Technical Workshop: Responding to the CENTCOM Vision

Environmental security is not formally classified as a ''vital mission'' in the USCENTCOM ranking of priorities in its area of responsibility. Rather, it is ranked as an ''other/important'' mission in Central Asia, thereby supporting the war making efforts in the region by improving stability of the regimes in the region. Environmental security is, however, the USCENTCOM primary mechanism for engagement in the region. USCENTCOM sees environmental issues as among the most destabilizing issues in the region; anything that can be done to ameliorate them, works to enhance stability. By environmental issues, USCENTCOM includes: water access, quality, and control, transboundary resource competition, migration of pollutants, land use, public health/HIV/Famine, and industrial pollution. Objectives of USCENTCOM work in Central Asia are: improving resource use, disaster response, international cooperation, and civil-military cooperation, particularly with the local military and between the local civilians and the U.S. military. Activities to date include assistance, education, and military-to-military contacts, bilateral and multilateral conferences on the issues, and interagency coordination in the region. The Comprehensive Threat Reduction program has been the backbone of its Central Asian funding.

Telecommunications: GSA Action Needs to Realize Benefits of Metropolitan Area Acquisition Program

A letter report issued by the General Accounting Office with an abstract that begins "The Metropolitan Area Acquisition (MAA) program provides local telecommunications services to federal agencies in certain U.S. cities. The General Services Administration (GSA) began the program in 1997 to achieve immediate, substantial, and sustained price reductions for local telecommunications for agencies; to expand their choices of high-quality services; and to encourage cross-agency sharing of resources. Service providers that are awarded contracts under the program are allowed to compete for GSA's FTS2001 long distance service contracts, so that federal agencies may potentially acquire end-to-end local and long distance telecommunications services from one source. Only five of the 19 metropolitan areas that were scheduled to switch from existing services to MAA services by or before March 2002 have done so. Although the program was intended to take advantage of emerging competition in the local telecommunications market, it has been beset by implementation challenges, including access and use of building riser cabling, the transfer of local numbers between service providers, and a contractor's financial problems. On top of the cost of the contract services, GSA charges customer agencies fees that range from about nine to 97 percent or from $1.20 …

Development of Low Cost Total Energy Exchange Devices for Reducing Building Energy Consumption (open access)

Development of Low Cost Total Energy Exchange Devices for Reducing Building Energy Consumption

The primary goal of this program is to develop a commercially viable enthalpy exchangers that exhibits performance comparable to state-of-the-art exchangers, meets flammability test standards, supports no biological growth, maintains mechanical integrity for a 10 year life (typical of competitive warrantees) and exhibits a total media raw material cost of approximately 1/5 of that of the competition. The first three program tasks were devoted to: (1) gathering background information on competitors and their methods of manufacturing; (2) establishing experimental and evaluation procedures for the program; (3) identifying potential desiccants, supports and binders to be tested; (4) preparing matrix combinations on a laboratory scale; (5) testing component combinations for equilibrium moisture uptakes at different relative humidities (isotherms) and dynamic moisture adsorption rates; (6) using media adsorption properties to models to predict exchanger performance; (7) estimating ease of manufacture and finished wheel costs; and (8) calculating raw material, wheel and cassette costs based on the best media formulations. Since the rotary enthalpy exchangers have high rotational speeds, uptake rate is at least as important as equilibrium moisture uptake. Therefore, a procedure and apparatus were developed to determine adsorption rate so that the Lewis number (the ratio of mass transfer resistance to heat …

2000 Census: Best Practices and Lessons Learned for More Cost-Effective Nonresponse Follow-up (open access)

2000 Census: Best Practices and Lessons Learned for More Cost-Effective Nonresponse Follow-up

A letter report issued by the General Accounting Office with an abstract that begins "Nonresponse follow-up--in which Census Bureau enumerators go door-to-door to count individuals who have not mailed back their questionnaires--was the most costly and labor intensive of all 2000 Census operations. According to Bureau data, labor, mileage, and administrative costs totaled $1.4 billion, or 22 percent of the $6.5 billion allocated for the 2000 Census. Several practices were critical to the Bureau's timely competition of nonresponse follow-up. The Bureau (1) had an aggressive outreach and promotion campaign, simplified questionnaire, and other efforts to boost the mail response rate and thus reduce the Bureau's nonresponse follow-up workload; (2) used a flexible human capital strategy that enabled it to meet its national recruiting and hiring goals and position enumerators where they were most needed; (3) called on local census offices to identify local enumeration challenges, such as locked apartment buildings and gated communities, and to develop action plans to address them; and (4) applied ambitious interim "stretch" goals that encouraged local census offices to finish 80 percent of their nonresponse follow-up workload within the first four weeks and be completely finished by the end of the eighth week, as opposed …

Tennessee Valley Authority: Information on Benchmarking and Electricity Rates

A letter report issued by the General Accounting Office with an abstract that begins "The Tennessee Valley Authority (TVA) declared its intent to become competitive by reducing its cost of power and becoming more financially flexible by reducing debt from $27.4 billion to $13.2 billion by 2007. Since the 1980s, TVA has used benchmarking to assess staffing levels for its nuclear program and it began to use benchmarking studies for its non-nuclear business units in 1998. Recent studies indicate that TVA's nuclear and transmission power supply units are close to the industry's best in terms of staffing efficiency. TVA has taken several actions to improve performance and efficiency, including reorganizing its human resources and business services organizations and automating its hydropower production facilities to reduce future staffing. TVA continues to utilize benchmarking to assist in identifying opportunities for improvement. TVA's current electricity rates are low when compared to 12 likely competitors and to national averages. Although TVA's electricity rates are relatively low, it is legislatively protected from most competition, and it has the statutory authority to raise rates. If TVA were to choose to raise electricity rates selectively and use the additional cash generated to repay debt, it could accelerate …

Preparation of radioactive rare earth targets for neutron capture study (open access)

Preparation of radioactive rare earth targets for neutron capture study

The understanding of thc details of nucleosynthesis in stars remains a great challenge. Though the basic mechanisms governing the processes have been known since the pioneering work of Burbidge, Burbidge, Fowler and Hoyle (l), we are now evolving into a condition where we can ask more specific questions. Of particular interest are the dynamics of the s ('slow') process. In this process the general condition is one in which sequential neutron captures occur at time scales long compared with the beta decay half lives of the capturing nuclides. The nucleosynthesis period for C or Ne burning stellar shells is believed to be in the year to few year time frame (2). This means that radionuclides with similar half lives to this burning period serve as 'branch point' nuclides. That is, there will be a competition between a capture to the next heavier isotope and a beta decay to the element of nexl higher atomic number. By understanding the abundances of these competing reactions we can learn about the dynamics of the nucleosynthesis process in the stellar medium. Crucial to this understanding is that we have a knowledge of the underlying neutron reaction cross sections on these unstable nuclides in the …

Nonlinear dynamics in flow through unsaturated fractured-porous media: Status and perspectives (open access)

Nonlinear dynamics in flow through unsaturated fractured-porous media: Status and perspectives

The need has long been recognized to improve predictions of flow and transport in partially saturated heterogeneous soils and fractured rock of the vadose zone for many practical applications, such as remediation of contaminated sites, nuclear waste disposal in geological formations, and climate predictions. Until recently, flow and transport processes in heterogeneous subsurface media with oscillating irregularities were assumed to be random and were not analyzed using methods of nonlinear dynamics. The goals of this paper are to review the theoretical concepts, present the results, and provide perspectives on investigations of flow and transport in unsaturated heterogeneous soils and fractured rock, using the methods of nonlinear dynamics and deterministic chaos. The results of laboratory and field investigations indicate that the nonlinear dynamics of flow and transport processes in unsaturated soils and fractured rocks arise from the dynamic feedback and competition between various nonlinear physical processes along with complex geometry of flow paths. Although direct measurements of variables characterizing the individual flow processes are not technically feasible, their cumulative effect can be characterized by analyzing time series data using the models and methods of nonlinear dynamics and chaos. Identifying flow through soil or rock as a nonlinear dynamical system is important …

The effect of specific chloride adsorption on the electrochemical behavior of ultrathin Pd films deposited on Pt(111) in acid solution (open access)

The effect of specific chloride adsorption on the electrochemical behavior of ultrathin Pd films deposited on Pt(111) in acid solution

The electrochemical behavior of thin Pd films supported on a Pt(111) electrode is investigated by cyclic voltammetry (CV) and in-situ Fourier transform infrared (FTIR) spectroscopy. It is demonstrated that in perchloric acid solution underpotential deposition of hydrogen (H{sub upd}) and hydroxyl adsorption (OH{sub ad}) is in strong competition with the adsorption of Cl- anions, the latter being present as a trace impurity in HClO{sub 4}. The interaction of Cl- with Pd is rather strong, controlling the adsorption of H{sub upd} and OH{sub ad} as well as the kinetic rate of CO oxidation. The microscopic insight (the binding sites) of the adsorbed CO (CO{sub ad}) and the rate of CO oxidation (established from CO2 production) on Pt(111) modified with a (sub)monolayer of Pd is elucidated by means of Fourier infrared (FTIR) spectroscopy. The appearance of both the characteristic Pt(111)-CO{sub ad} and Pt(111)1 ML Pd-CO{sub ad} stretching bands on a Pt(111) surface covered by 0.5 ML Pd confirms previous findings that the Pd atoms agglomerate into islands and that the bare Pt areas and the Pd islands behave according to their own surface chemistry. The systematic increase of the Pd surface coverage results in a gradual change in the catalytic properties of …

Congestion Management Requirements, Methods and Performance Indices (open access)

Congestion Management Requirements, Methods and Performance Indices

Transmission congestion occurs when there is insufficient transmission capacity to simultaneously accommodate all requests for transmission service within a region. Historically, vertically integrated utilities managed this condition by constraining the economic dispatch of generators with the objective of ensuring security and reliability of their own and/or neighboring systems. Electric power industry restructuring has moved generation investment and operations decisions into the competitive market but has left transmission as a communal resource in the regulated environment. This mixing of competitive generation and regulated transmission makes congestion management difficult. The difficulty is compounded by increases in the amount of congestion resulting from increased commercial transactions and the relative decline in the amount of transmission. Transmission capacity, relative to peak load, has been declining in all regions of the U.S. for over a decade. This decline is expected to continue. Congestion management schemes used today have negative impacts on energy markets, such as disruptions and monetary penalties, under some conditions. To mitigate these concerns various congestion management methods have been proposed, including redispatch and curtailment of scheduled energy transmission. In the restructured electric energy industry environment, new congestion management approaches are being developed that strive to achieve the desired degree of reliability while …

Market leadership by example: Government sector energy efficiency in developing countries (open access)

Market leadership by example: Government sector energy efficiency in developing countries

Government facilities and services are often the largest energy users and major purchasers of energy-using equipment within a country. In developing as well as industrial countries, government ''leadership by example'' can be a powerful force to shift the market toward energy efficiency, complementing other elements of a national energy efficiency strategy. Benefits from more efficient energy management in government facilities and operations include lower government energy bills, reduced greenhouse gas emissions, less demand on electric utility systems, and in many cases reduced dependence on imported oil. Even more significantly, the government sector's buying power and example to others can generate broader demand for energy-efficient products and services, creating entry markets for domestic suppliers and stimulating competition in providing high-efficiency products and services. Despite these benefits, with the exception of a few countries government sector actions have often lagged behind other energy efficiency policies. This is especially true in developing countries and transition economies - even though energy used by public agencies in these countries may represent at least as large a share of total energy use as the public sector in industrial economies. This paper summarizes work in progress to inventory current programs and policies for government sector energy efficiency …

U.S. Team Green Building Challenge 2002

Flier about the U.S. Team and its projects participating in the International Green Building Challenge. Along with many other countries, the United States accepted the Green Building Challenge (GBC), an international effort to evaluate and improve the performance of buildings worldwide. GBC started out in 1996 as a competition to determine which country had the greenest buildings; it evolved into a cooperative process among the countries to measure the performance of green buildings. Although the auto industry can easily measure efficiency in terms of miles per gallon, the buildings industry has no standard way to quantify energy and environmental performance. The Green Building Challenge participants hope that better tools for measuring the energy and environmental performance of buildings will be an outcome of their efforts and that these tools will lead to higher and better performance levels in buildings around the world. The ultimate goal is to design, construct, and operate buildings that contribute to global sustainability by conserving and/or regenerating natural resources and minimizing nonrenewable energy use. The United States' Green Building Challenge Team '02 selected five buildings from around the country to serve as case studies; each of the five U.S. building designs (as well as all international …

Technical Potential for Peak Load Management Programs in New Jersey (open access)

Technical Potential for Peak Load Management Programs in New Jersey

Restructuring is attempting to bring the economic efficiency of competitive markets to the electric power industry. To at least some extent it is succeeding. New generation is being built in most areas of the country reversing the decades-long trend of declining reserve margins. Competition among generators is typically robust, holding down wholesale energy prices. Generators have shown that they are very responsive to price signals in both the short and long term. But a market that is responsive only on the supply side is only half a market. Demand response (elasticity) is necessary to gain the full economic advantages that restructuring can offer. Electricity is a form of energy that is difficult to store economically in large quantities. However, loads often have some ability to (1) conveniently store thermal energy and (2) defer electricity consumption. These inherent storage and control capabilities can be exploited to help reduce peak electric system consumption. In some cases they can also be used to provide system reliability reserves. Fortunately too, technology is helping. Advances in communications and control technologies are making it possible for loads ranging from residential through commercial and industrial to respond to economic signals.

Key Technologies for the Development of Fossil Fuels in the 21st Century

As the world faces growing economic and environmental challenges, the energy mix that fuels the global economy is undergoing rapid change. Yet how this change will evolve in the future is uncertain. What will be the sources of primary energy in twenty years? In fifty years? In different regions of the globe? How will this energy be utilized? Fossil energy currently supplies about ninety percent of the world's primary energy. In Japan this number is closer to eighty percent. It is clear that fossil energy will be a major supplier of global energy for some time to come, but what is not clear is the types of fossil energy and how it will be utilized. The degree to which the abundant supplies of fossil energy, especially coal, will continue to play a major role will depend on whether technology will provide safe, clean and affordable fuel for electricity and transportation. Technology will not only assist in finding more fossil energy in varying regions of the globe but, most importantly, will play a strong role in efficient utilization and in determining the cost of delivering that energy. Several important questions will have to be answered: (1) Will cost effective technologies be …

Coeur d'Alene Tribe Fisheries Program Research, Monitoring and Evaluation Plan; Implementation of Fisheries Enhancement Opportunities on the Coeur d'Alene Reservation, 1997-2002 Technical Report. (open access)

Coeur d'Alene Tribe Fisheries Program Research, Monitoring and Evaluation Plan; Implementation of Fisheries Enhancement Opportunities on the Coeur d'Alene Reservation, 1997-2002 Technical Report.

Westslope cutthroat trout (Oncorhynchus clarki lewisi) and bull trout (Salvelinus confluentus) are currently of special concern regionally and are important to the culture and subsistence needs of the Coeur d'Alene Tribe. The mission of the Coeur d'Alene Tribe Fisheries Program is to restore and maintain these native trout and the habitats that sustain them in order to provide subsistence harvest and recreational fishing opportunities for the Reservation community. The adfluvial life history strategy exhibited by westslope cutthroat and bull trout in the Lake Coeur d'Alene subbasin makes these fish susceptible to habitat degradation and competition in both lake and stream environments. Degraded habitat in Lake Coeur d'Alene and its associated streams and the introduction of exotic species has lead to the decline of westslope cutthroat and listing of bull trout under the endangered species act (Peters et al. 1998). Despite the effects of habitat degradation, several streams on the Reservation still maintain populations of westslope cutthroat trout, albeit in a suppressed condition (Table 1). The results of several early studies looking at fish population status and habitat condition on the Reservation (Graves et al. 1990; Lillengreen et al. 1993, 1996) lead the Tribe to aggressively pursue funding for habitat restoration …

Michael Daugherty's Red Cape Tango: A Comparative Study of the Original Version for Symphony Orchestra and its Transcription for Wind Orchestra, with Four Recitals of Selected Works by Beethoven, Dvorák, Verdi, Bartók and Daugherty

Access: Use of this item is restricted to the UNT Community
Michael Daugherty has created his niche in the music world by composing works inspired by icons of American popular culture. Red Cape Tango is the final movement of his Metropolis Symphony, a work inspired by the life and times of the comic book character Superman. This movement in particular deals with the death of the superhero through the use of musical elements, most notably the Latin Sequence of the Mass for the Dead, Dies irae. Daugherty's ingenuity in blending profoundly dark subjects with humor is particularly evident in this work. Death is personified as a temptress and lures Superman through the power of a seductive tango. This study concentrates on Daugherty's compositional style and its impact in musical circles. A transcription for wind orchestra was created by another composer/conductor precisely because of the need to bring such an important work to another medium, thus making it accessible to a wider audience. In addition, this study looks at the changes in instrumentation necessary to create a second, equally formidable version of the work.
