A letter report issued by the General Accounting Office with an abstract that begins "Section 366 of the National Defense Authorization Act for Fiscal Year 2003 required the Secretary of Defense to develop a report outlining a comprehensive plan to address training constraints caused by limitations on the use of military lands, marine areas, and air space that are available in the United States and overseas for training. The foundation for that plan is an inventory identifying training resources, capacities and capabilities, and limitations. In response to section 366, this report discusses the extent to which (1) the Office of the Secretary of Defense's (OSD) training range inventory is sufficient for developing the comprehensive training range plan and (2) OSD's 2004 training range report meets other requirements mandated by section 366."

A letter report issued by the General Accounting Office with an abstract that begins "Russia's continued operation of three plutonium production reactors poses a serious proliferation threat. The Department of Energy's (DOE) Elimination of Weapons-Grade Plutonium Production program seeks to facilitate the reactors' closure by building or refurbishing replacement fossil fuel plants. This report (1) describes DOE's efforts to manage and implement the program, (2) assesses the challenges DOE faces in achieving its goal of shutting down the reactors, and (3) identifies DOE's current expenditures and projected program costs."

A letter report issued by the General Accounting Office with an abstract that begins "The Substance Abuse and Mental Health Services Administration (SAMHSA) is the lead federal agency responsible for improving the quality and availability of prevention and treatment services for substance abuse and mental illness. The upcoming reauthorization review of SAMHSA will enable the Congress to examine the agency's management of its grant programs and plans for converting its block grants to performance partnership grants, which will hold states more accountable for results. GAO was asked to provide the Congress with information about SAMHSA's (1) strategic planning efforts, (2) efforts to manage its workforce, and (3) partnerships with state and community-based grantees."

A letter report issued by the General Accounting Office with an abstract that begins "Both the government and the private sector are increasingly using "data mining"--that is, the application of database technology and techniques (such as statistical analysis and modeling) to uncover hidden patterns and subtle relationships in data and to infer rules that allow for the prediction of future results. As has been widely reported, many federal data mining efforts involve the use of personal information that is mined from databases maintained by public as well as private sector organizations. GAO was asked to survey data mining systems and activities in federal agencies. Specifically, GAO was asked to identify planned and operational federal data mining efforts and describe their characteristics."

A letter report issued by the General Accounting Office with an abstract that begins "One of the primary purposes of the Telecommunications Act of 1996 was to promote competition in telecommunication markets, but wire-based competition has not developed as fully as expected. However, a new kind of entrant, called broadband service providers (BSP), offers an alternative wire- based option for local telephone, subscription television, and high- speed Internet services to consumers in the markets they have chosen to enter. This report provides information on (1) BSPs' business strategy, (2) the impact of BSPs' market entry on incumbent companies' behavior and consumer prices for telecommunications services, (3) the key factors that BSPs consider when making decisions about which local markets to enter, and (4) the success of BSPs in attaining subscribership and any key factors that may limit their success. We developed a case-study approach to compare 6 cities where a BSP has been operating for at least 1 year with 6 similar cities that do not have such a competitor. The 6 markets with a BSP presently account for more than 20 percent of the households nationwide that are in areas where BSPs currently offer the three-service package, but the …

A letter report issued by the General Accounting Office with an abstract that begins "Numerous federal agencies conduct water, power, or resource management activities affecting the fish and wildlife of the Columbia River Basin, as well as the 13 tribes residing there. These agencies, such as the Bonneville Power Administration (Bonneville), Army Corps of Engineers, and Forest Service, and regulatory agencies, such as the National Marine Fisheries Service, are also responsible for protecting, sustaining, and enhancing fish and wildlife resources in the basin and involving the tribes in the process. Recently, Bonneville's financial position deteriorated significantly, and some tribes in the basin challenged Bonneville's actions modifying funding of fish and wildlife activities in federal court. In this context, GAO agreed to (1) identify and describe the laws, treaties, executive orders, and court decisions that define federal responsibilities to perform activities benefiting fish and wildlife in the basin and involve the tribes, and (2) describe the plans and programs that guide these respective fish and wildlife activities. In accordance with our policy to refrain from addressing matters that are in litigation, GAO did not examine any issues that are before the court."

A letter report issued by the Government Accountability Office with an abstract that begins "Auto crashes kill or injure millions of people each year. Information about where and why such crashes occur is important in reducing this toll, both for identifying particular hazards and for planning safety efforts at the state and federal levels. Differences in the quality of state traffic data from state to state, however, affect the usability of data for these purposes. The National Highway Traffic Safety Administration (NHTSA) administers a grant program to help states improve the safety data systems that collect and analyze crash data from police and sheriff's offices and other agencies, and the Congress is considering whether to reauthorize and expand the program. The Senate Appropriations Committee directed GAO to study state systems and the grant program. Accordingly, GAO examined (1) the quality of state crash information, (2) the activities states undertook to improve their traffic records systems and any progress made, and (3) NHTSA's oversight of the grant program."

A letter report issued by the General Accounting Office with an abstract that begins "With the heavy pace of operations in support of the war on terrorism, the Department of Defense (DOD) and the Air Force have become increasingly concerned about their aging aerial refueling aircraft. We last reviewed the aerial refueling fleet in 1996 and found that KC-135 aircraft were aging and becoming increasingly costly to maintain and operate. In December 2001, we began new work on the Air Force's requirements for refueling aircraft. However, we suspended our work several times to provide testimony and other products on the condition of the current fleet and Air Force plans to accelerate replacement. We were asked to review (1) the extent to which the current fleet has met aerial refueling needs, and the cost and effort to operate and sustain the fleet, (2) DOD's current refueling requirements, and (3) options to meet future aerial refueling needs."

A letter report issued by the Government Accountability Office with an abstract that begins "The Medicare appeals process has been the subject of widespread concern in recent years because of the time it takes to resolve appeals of denied claims. Two federal agencies play a role in deciding appeals--the Department of Health and Human Services (HHS) and the Social Security Administration (SSA). Currently, neither agency manages and oversees the entire multilevel process. In the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA), Congress mandated that SSA transfer its responsibility for adjudicating Medicare appeals to HHS between July 1, 2005, and October 1, 2005. In addition, it directed the two agencies to develop a transfer plan addressing 13 specific elements related to the transfer. GAO's objective was to determine whether the plan is sufficient to ensure a smooth and timely transition."

A letter report issued by the General Accounting Office with an abstract that begins "Because of concerns raised about the accuracy of National Marine Fisheries Service (NMFS) stock assessments, GAO reviewed the assessments for five species of Pacific groundfish: Pacific hake and four types of rockfish--bocaccio, canary, darkblotched, and yelloweye. Specifically, for these five species GAO (1) assessed the reliability of NMFS' stock assessments, (2) identified which relevant recommendations from NMFS' stock assessment improvement plan have been implemented and which have not, and (3) identified the costs associated with planned and ongoing improvements to groundfish stock assessments."

A letter report issued by the General Accounting Office with an abstract that begins "In the 2 years since passage of the Aviation and Transportation Security Act (ATSA), the Transportation Security Administration (TSA) has primarily focused its efforts on improving aviation security through enhanced passenger and baggage screening. The act also contained provisions directing TSA to take actions to improve the security of airport perimeters, access controls, and airport workers. GAO was asked to assess TSA's efforts to: (1) evaluate the security of airport perimeters and the controls that limit access into secured airport areas, (2) help airports implement and enhance perimeter security and access controls by providing them funding and technical guidance, and (3) implement measures to reduce the potential security risks posed by airport workers."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 1980, the Congress has required the Social Security Administration (SSA) to conduct demonstration projects to test the effectiveness of possible program changes that could encourage individuals to return to work and decrease their dependence on Disability Insurance (DI) benefits. To conduct these demonstrations, the Congress authorized SSA, on a temporary basis, to waive certain DI and Medicare program rules and to use Social Security Trust Funds. The Congress required GAO to review SSA's use of its DI demonstration authority and to make a recommendation as to whether this authority should be made permanent."

A letter report issued by the General Accounting Office with an abstract that begins "Geothermal energy is heat from the earth that can be used to generate electricity. The Department of the Interior's Bureau of Land Management (BLM) has the primary responsibility for leasing public lands to private companies for geothermal development. In addition, the Secretary of each military department has the authority to develop geothermal resources on military lands and to keep the proceeds from the sale of electricity generated from those resources for use by the Department of Defense. The Navy's Geothermal Program Office, located at the China Lake Naval Air Weapons Station in California, manages and develops geothermal resources for the military. Currently, two geothermal power plants at China Lake are the only ones on military lands. A private company, which built, owns, and operates the power plants at China Lake, sells the electricity to a utility company and pays the Navy royalties on these sales as well as other types of compensation. GAO was asked to provide information on (1) the Navy's annual revenues from the geothermal facility at China Lake, (2) how the Navy uses the revenues it collects from the geothermal facility, (3) the …

The standard cross-section library for light-water reactor (LWR) analyses used by the ORIGEN-S depletion and decay code has been extensively updated. This work entailed the development of broad multigroup neutron cross sections for ORIGEN-S from several sources of pointwise continuous-energy cross-section evaluations, including the U.S. Evaluated Nuclear Data Files ENDF/B-VI Release 7, the Fusion Evaluated Nuclear Data Library FENDL-2.0, and the European Activation File EAF-99. The pointwise cross sections were collapsed to a three-group structure using a continuous-energy neutron flux spectrum representative of the typical neutronic conditions of typical LWR fuel and formatted for use by ORIGEN-S. In addition, the fission-product library has been expanded to include ENDF/B-VI fission yield data for 30 fissionable actinides. The processing codes and procedures are explained. Preliminary verification studies using the updated libraries were performed using the modules of the SCALE (Standardized Computer Analyses for Licensing Evaluation) system. Comparisons between the previous basic ORIGEN-S libraries and the updated libraries developed in this work are presented.

We describe a general, physics-based approach to numericalreconstruction of the geometrical structure and mechanical properties ofnatural sedimentary rock in 3D. Our procedure consists of three mainsteps: sedimentation, compaction, and diagenesis, followed by theverification of rock mechanical properties. The dynamic geologicprocesses of grain sedimentation and compaction are simulated by solvinga dimensionless form of Newton's equations of motion for an ensemble ofgrains. The diagenetic rock transformation is modeled using a cementationalgorithm, which accounts for the effect of rock grain size on therelative rate of cement overgrowth. Our emphasis is on unconsolidatedsand and sandstone. The main input parameters are the grain sizedistribution, the final rock porosity, the type and amount of cement andclay minerals, and grain mechanical properties: the inter-grain frictioncoefficient, the cement strength, and the grain stiffness moduli. We usea simulated 2D Fontainebleau sandstone to obtain the grain mechanicalproperties. This Fontainebleau sandstone is also used to study theinitiation, growth, and coalescence of micro-cracks under increasingvertical stress. The box fractal dimension of the micro-crackdistribution, and its variation with the applied stress areestimated.

This paper presents a case study of the residential heat pump water heater (HPWH) market. Its principal purpose is to evaluate the extent to which the HPWH will penetrate the residential market sector, given current market trends, producer and consumer attributes, and technical parameters. The report's secondary purpose is to gather background information leading to a generic framework for conducting market analyses of technologies. This framework can be used to compare readiness and to factor attributes of market demand back into product design. This study is a rapid prototype analysis rather than a detailed case analysis. For this reason, primary data collection was limited and reliance on secondary sources was extensive. Despite having met its technical goals and having been on the market for twenty years, the HPWH has had virtually no impact on contributing to the nation's water heating. In some cases, HPWH reliability and quality control are well below market expectations, and early units developed a reputation for unreliability, especially when measured against conventional water heaters. In addition to reliability problems, first costs of HPWH units can be three to five times higher than conventional units. Without a solid, well-managed business plan, most consumers will not be drawn …

This is a compilation of my patents issued from 1997 to 2002, generally describing interferometer techniques that modify the coherence properties of broad-bandwidth light and other waves, with applications to Doppler velocimetry, range finding, imaging and spectroscopy. Patents are tedious to read in their original form. In an effort to improve their readability I have embedded the Figures throughout the manuscript, put the Figure captions underneath the Figures, and added section headings. Otherwise I have resisted the temptation to modify the words, though I found many places which could use healthy editing. There may be minor differences with the official versions issued by the US Patent and Trademark Office, particularly in the claims sections. In my shock physics work I measured the velocities of targets impacted by flyer plates by illuminating them with laser light and analyzing the reflected light with an interferometer. Small wavelength changes caused by the target motion (Doppler effect) were converted into fringe shifts by the interferometer. Lasers having long coherence lengths were required for the illumination. While lasers are certainly bright sources, and their collimated beams are convenient to work with, they are expensive. Particularly if one needs to illuminate a wide surface area, then …

Boiling temperature measurements have been made for saturated ternary solutions of NaCl + KNO{sub 3} + H{sub 2}O and NaNO{sub 3} + KNO{sub 3} + H{sub 2}O over the full solute mole fraction range, along with the limiting binary solutions NaCl + H{sub 2}O, NaNO{sub 3} + H{sub 2}O, and KNO{sub 3} + H{sub 2}O. Boiling temperatures have also been measured for the quaternary NaCl + NaNO{sub 3} + KNO{sub 3} + H{sub 2}O mixtures with KNO{sub 3}:NaNO{sub 3} mole ratios of 1.01 and 1.19, which corresponding to the eutectic ratio and a near-eutectic ratio for the NaNO{sub 3} + KNO{sub 3} + H{sub 2}O subsystem. The maximum boiling temperature found for the NaCl + KNO{sub 3} + H{sub 2}O system is 134 C and for the NaNO{sub 3} + KNO{sub 3} + H{sub 2}O system is 160 C, but boiling temperatures as high as 196 C were measured the NaCl + NaNO{sub 3} + KNO{sub 3} + H{sub 2}O system. These mixture compositions correspond to the major mineral assemblages that are predicted to control the deliquescence relative humidity of salts found by leaching dust samples from the proposed nuclear repository at Yucca Mountain, Nevada.
