A letter report issued by the Government Accountability Office with an abstract that begins "DODIG has taken multiple steps, in collaboration with the service IGs in some instances, to improve DOD’s ability to process military whistleblower reprisal cases in a timely manner. Timeliness is important to ensure the reliability of evidence and appropriate resolution of reprisal allegations. However, DODIG has generally not met statutory requirements to report on investigations within 180 days, or to provide alternative notification. DODIG has undertaken efforts to improve timeliness by, for example, eliminating a time-consuming phase of its investigative process. However, DOD’s efforts are hampered by unreliable and incomplete data. For instance, GAO found that DODIG has not consistently or accurately recorded key dates to track how long investigations take to complete. Without key timeliness data, DODIG may have difficulty in identifying process areas requiring improvement and evaluating the impact of reforms. Further, the absence of this information limits congressional decision makers’ ability to provide oversight of DOD’s whistleblower reprisal investigative program."

A letter report issued by the Government Accountability Office with an abstract that begins "As the responsible DOD agency for leading, advocating, and coordinating all DOD efforts to defeat improvised explosive devices (IED) the Joint IED Defeat Organization (JIEDDO) was directed to develop DOD’s counter-IED strategic plan in February 2006 under DOD Directive 2000.19E. As previously recommended by GAO, JIEDDO has made several attempts to develop such a plan, but its strategic-planning actions have not followed leading strategic-management practices or have since been discontinued. For example, JIEDDO’s 2007 strategic plan did not contain a means of measuring its performance outcomes—a leading strategic-management practice. In addition, JIEDDO’s 2009–2010 strategic plan contained performance measures, but JIEDDO discontinued using these measures because it later determined that the measures were not relevant to the organization’s goals. Although DOD tasked JIEDDO to develop its counter-IED strategic plan, DOD has not translated DOD’s counter-IED general mission objective of eliminating IEDs as a weapon of strategic influence into actionable goals and objectives. JIEDDO issued a new counter-IED strategic plan in January 2012; however, the new plan does not apply to all other counter-IED efforts departmentwide, only to those managed by JIEDDO. Consequently, JIEDDO’s new strategic plan alone …

A letter report issued by the Government Accountability Office with an abstract that begins "GAO has prepared this report to assist Congress in identifying and addressing debt management challenges. Since 1995, the statutory debt limit has been increased 12 times to its current level of $14.294 trillion. The Department of the Treasury (Treasury) recently notified Congress that the current debt limit could be reached as early as April 5, 2011, and the Congressional Budget Office (CBO) projects that under current law debt subject to the limit will exceed $25 trillion in 2021. This report (1) describes the actions that Treasury traditionally takes to manage debt near the limit, (2) analyzes the effects that approaching the debt limit has had on the market for Treasury securities, and (3) describes alternative mechanisms that would permit consideration of the link between policy decisions and the effect on debt when or before decisions are made. GAO analyzed Treasury and market data; interviewed Treasury officials, budget and legislative experts, and market participants; and reviewed practices in selected countries."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO found that for the 2008 to 2010 time frame covered by this review, the participating judges' share of normal cost was, on average, about 41 percent of the Judicial Survivors' Annuities System (JSAS) total normal costs, and the federal government's share of normal cost was about 59 percent of JSAS total normal costs. The federal government's share of JSAS normal costs increased over the years included in GAO's review, from approximately 53 percent in plan year 2008, to 61 percent in plan year 2009, and to approximately 64 percent in plan year 2010. The increase was a result of (1) less favorable actual economic and demographic outcomes over this period than predicted by the actuarial assumptions and (2) changes in actuarial assumptions regarding future economic and demographic outcomes."

A letter report issued by the Government Accountability Office with an abstract that begins "During fiscal years 2006 through 2012, the Department of Veterans Affairs (VA) had higher than estimated resources available for facility maintenance and improvement--referred to as non-recurring maintenance (NRM); these resources accounted for the $4.9 billion in VA's NRM spending that exceeded budget estimates. The additional resources came from two sources. First, VA spent less than it estimated on non-NRM, facility-related activities such as administrative functions, utilities, and rent, which allowed VA to spend over $2.5 billion more than originally estimated. Lower spending for administrative functions, utilities, and rent accounted for most of the resources estimated but not spent on non-NRM activities. Given that VA has consistently overestimated the costs of such activities in recent years, VA's budget estimates for its non-NRM activities may not be reliable. Second, more than $2.3 billion of the higher than estimated spending on NRM can be attributed to VA having higher than estimated budget resources available. In some years VA received higher appropriations from Congress than requested and supplemental appropriations for NRM--such as those included in the American Recovery and Reinvestment Act of 2009. The additional budget resources VA used for …

A letter report issued by the Government Accountability Office with an abstract that begins "Manufacturers and commercial licensees have taken a variety of actions to improve receiver performance. For some services, industry associations-- comprised of manufacturers, commercial licensees, and others--have developed voluntary standards that are often used to design and procure receivers, such as those in cell phones and televisions, and to help improve receiver performance. Stakeholders also reported privately negotiating to resolve interference problems and sharing of information as having helped improve receiver performance."

The U.S. Fire Administration (USFA) - which includes the National Fire Academy (NFA) - is currently an entity within the Federal Emergency Management Agency (FEMA) of the Department of Homeland Security (DHS). The objective of the USFA is to significantly reduce the nation's loss of life from fire, while also achieving a reduction in property loss and non-fatal injury due to fire. In the 112th Congress, debate over the USFA budget focuses on whether the USFA is receiving sufficient funding to accomplish its mission, given that appropriations for USFA have consistently been well below the agency's authorized level. An ongoing issue is the viability and status of the USFA and National Fire Academy within the Department of Homeland Security.

The U.S. Constitution, in Article I, Section 6, authorizes compensation for Members of Congress "ascertained by law, and paid out of the Treasury of the United States." Throughout American history, Congress has relied on three different methods in adjusting salaries for Members. Standalone legislation was last used to provide increases in 1990 and 1991. It was the only method used by Congress for many years. The second method, under which annual adjustments took effect automatically unless disapproved by Congress, was established in 1975. A third method for adjusting Member pay is congressional action pursuant to recommendations from the President, based on the recommendations of the Citizens' Commission on Public Service and Compensation established in the 1989 Ethics Reform Act.

This report details the chemical and radionuclide contaminant results for the characterization of the 2010 Fourth Quarter sampling of Tank 50 for the Saltstone Waste Acceptance Criteria (WAC). Information from this characterization will be used by Liquid Waste Operations (LWO) to support the transfer of low-level aqueous waste from Tank 50 to the Salt Feed Tank in the Saltstone Facility in Z-Area, where the waste will be immobilized. This information is also used to update the Tank 50 Waste Characterization System. The following conclusions are drawn from the analytical results provided in this report: (1) The concentrations of the reported chemical and radioactive contaminants were less than their respective WAC targets or limits unless noted in this section. (2) The reported detection limits for {sup 94}Nb, {sup 247}Cm and {sup 249}Cf are above the requested limits from Reference 2. However, they are below the limits established in Reference 3. (3) There is an estimated concentration of trimethylbenzene (2.25 mg/L). This is not a WAC analyte, but it is the first time this organic compound has been detected in a quarterly WAC sample from Tank 50. (4) The reported detection limit for Norpar 13 is greater than the limit from Table …

The focus of the research performed under this grant has been the investigation of spin transport in magnetic semiconductor heterostructures. The interest in these systems is motivated both by their intriguing physical properties, as the physical embodiment of a spin-polarized Fermi liquid, as well as by their potential applications as spintronics devices. In our work we have analyzed several different problems that affect the spin dynamics in single and bi-layer spin-polarized two-dimensional (2D) systems. The topics of interests ranged from the fundamental aspects of the electron-electron interactions, to collective spin and charge density excitations and spin transport in the presence of the spin-orbit coupling. The common denominator of these subjects is the impact at the macroscopic scale of the spin-dependent electron-electron interaction, which plays a much more subtle role than in unpolarized electron systems. Our calculations of several measurable parameters, such as the excitation frequencies of magneto-plasma modes, the spin mass, and the spin transresistivity, propose realistic theoretical estimates of the opposite-spin many-body effects, in particular opposite-spin correlations, that can be directly connected with experimental measurements.

The research project focuses on the following topics: a) removal of artifacts in the Doppler spectra from the ARM cloud radars, b) development of the second generation Active Remote Sensing of Cloud Layers (ARSCL) cloud data products, and c) evaluation of ARM cloud property retrievals within the framework of the EarthCARE simulator. We continue to pursue research on areas related to radiative transfer, atmospheric heating rates and related dynamics (topics of interest to the ARM science community at this time) and to contribute on an ad-hoc basis to the science of other ARM-supported principal investigators.

In a specially designed tensile fracture experiment on bicrysal thin films, it was discovered that the fracture toughness of a thin film is not a material constant; rather, as the film becomes thinner it decreases much faster than the prediction of conventional theory. A detailed analysis revealed that this is caused by the mismatch of crystalline structures and, more importantly, with an appropriate crystalline orientation distribution the decrease may be suppressed. This result shed light on the fundamentals of crystal behaviors in pressurized matters. It also provides a promising solution to minimize unexpected failures in nano/micro-electromechanical systems, and therefore is of immense technological importance.

At the request of the Pacific Northwest National Laboratory, an in-depth analysis of the rapidly evolving state of real estate investments, high-performance building technology, and interest in efficiency was conducted by HaydenTanner, LLC, for the U.S. Department of Energy (DOE) Building Technologies Program. The analysis objectives were • to evaluate the link between high-performance buildings and their market value • to identify core messaging to motivate owners, investors, financiers, and others in the real estate sector to appropriately value and deploy high-performance strategies and technologies across new and existing buildings • to summarize financial mechanisms that facilitate increased investment in these buildings. To meet these objectives, work consisted of a literature review of relevant writings, examination of existing and emergent financial and policy mechanisms, interviews with industry stakeholders, and an evaluation of the value implications through financial modeling. This report documents the analysis methodology and findings, conclusion and recommendations. Its intent is to support and inform the DOE Building Technologies Program on policy and program planning for the financing of high-performance new buildings and building retrofit projects.

Each year, more than 25 million vehicles reach the end of their service life throughout the world, and this number is rising rapidly because the number of vehicles on the roads is rapidly increasing. In the United States, more than 95% of the 10-15 million scrapped vehicles annually enter a comprehensive recycling infrastructure that includes auto parts recyclers/dismantlers, remanufacturers, and material recyclers (shredders). Today, over 75% of automotive materials, primarily the metals, are profitably recycled via (1) parts reuse and parts and components remanufacturing and (2) ultimately by the scrap processing (shredding) industry. The process by which the scrap processors recover metal scrap from automobiles involves shredding the obsolete automobile hulks, along with other obsolete metal-containing products (such as white goods, industrial scrap, and demolition debris), and recovering the metals from the shredded material. The single largest source of recycled ferrous scrap for the iron and steel industry is obsolete automobiles. The non-metallic fraction that remains after the metals are recovered from the shredded materials - commonly called shredder residue - constitutes about 25% of the weight of the vehicle, and it is disposed of in landfills. This practice is not environmentally friendly, wastes valuable resources, and may become uneconomical. …

The cadmium shim arms in the NBSR undergo burnup during reactor operation and hence, require periodic replacement. Presently, the shim arms are replaced after every 25 cycles to guarantee they can maintain sufficient shutdown margin. Two prior reports document the expected change in the 113Cd distribution because of the shim arm depletion. One set of calculations was for the present high-enriched uranium fuel and the other for the low-enriched uranium fuel when it was in the COMP7 configuration (7 inch fuel length vs. the present 11 inch length). The depleted 113Cd distributions calculated for these cores were applied to the current design for an equilibrium low-enriched uranium core. This report details the predicted effects, if any, of shim arm depletion on the shim arm worth, the shutdown margin, power distributions and kinetics parameters.

In this study, we evaluate the possibility of monitoring soil moisture variation using tomographic ground penetrating radar travel time data through Bayesian inversion, which is integrated with entropy memory function and pilot point concepts, as well as efficient sampling approaches. It is critical to accurately estimate soil moisture content and variations in vadose zone studies. Many studies have illustrated the promise and value of GPR tomographic data for estimating soil moisture and associated changes, however, challenges still exist in the inversion of GPR tomographic data in a manner that quantifies input and predictive uncertainty, incorporates multiple data types, handles non-uniqueness and nonlinearity, and honors time-lapse tomograms collected in a series. To address these challenges, we develop a minimum relative entropy (MRE)-Bayesian based inverse modeling framework that non-subjectively defines prior probabilities, incorporates information from multiple sources, and quantifies uncertainty. The framework enables us to estimate dielectric permittivity at pilot point locations distributed within the tomogram, as well as the spatial correlation range. In the inversion framework, MRE is first used to derive prior probability density functions (pdfs) of dielectric permittivity based on prior information obtained from a straight-ray GPR inversion. The probability distributions are then sampled using a Quasi-Monte Carlo (QMC) …

Presented in this report are radionuclide concentrations required as part of the program of qualifying Sludge Batch Seven (SB7) for processing in the Defense Waste Processing Facility (DWPF). The SB7 material is currently in Tank 51 being washed and prepared for transfer to Tank 40. The acceptance evaluation needs to be completed prior to the transfer of the material in Tank 51 to Tank 40. The sludge slurry in Tank 40 has already been qualified for DWPF and is currently being processed as SB6. The radionuclide concentrations were measured or estimated in the Tank 51 SB7 Qualification Sample prepared at Savannah River National Laboratory (SRNL). This sample was prepared from the three liter qualification sample of Tank 51 sludge slurry (HTF-51-10-125) received on September 18, 2010. The sample was delivered to SRNL where it was initially characterized in the Shielded Cells. With consultation from the Liquid Waste Organization, the qualification sample was then modified by several washes and decants, which included addition of Pu from H Canyon and sodium nitrite per the Tank Farm corrosion control program. This final slurry now has a composition expected to be similar to that of the slurry in Tank 51 after final preparations have …

A Demonstration tokamak (Demo) is an essential next step toward a magnetic-fusion based reactor. One based on advanced-tokamak (AT) plasmas is especially appealing because of its relative compactness. However, it will require many plasma measurements to provide the necessary signals to feed to ancillary systems to protect the device and control the plasma. This note addresses the question of how much intrusion into the blanket system will be required to allow the measurements needed to provide the information required for plasma control. All diagnostics will require, at least, the same shielding designs as planned for ITER, while having the capability to maintain their calibration through very long pulses. Much work is required to define better the measurement needs and the quantity and quality of the measurements that will have to be made, and how they can be integrated into the other tokamak structures.

Tall wind turbines, with hub heights at 80 m or above, can extract large amounts of energy from the atmosphere because they are likely to encounter higher wind speeds, but they face challenges given the complex nature of wind flow and turbulence at these heights in the boundary layer. Depending on whether the boundary layer is stable, neutral, or convective, the mean wind speed, direction, and turbulence properties may vary greatly across the tall turbine swept area (40 to 120 m AGL). This variability can cause tall turbines to produce difference amounts of power during time periods with identical hub height wind speeds. Using meteorological and power generation data from a West Coast North American wind farm over a one-year period, our study synthesizes standard wind park observations, such as wind speed from turbine nacelles and sparse meteorological tower observations, with high-resolution profiles of wind speed and turbulence from a remote sensing platform, to quantify the impact of atmospheric stability on power output. We first compare approaches to defining atmospheric stability. The standard, limited, wind farm operations enable the calculation only of a wind shear exponent ({alpha}) or turbulence intensity (I{sub U}) from cup anemometers, while the presence at this …
