A statement of record issued by the Government Accountability Office with an abstract that begins "DOD is in the process of implementing this human capital system, and according to DOD, about 212,000 civilian employees are currently under the system. On February 11, 2009, however, the House Armed Services Committee and its Subcommittee on Readiness asked DOD to halt conversions of any additional employees to NSPS until the administration and Congress could properly address the future of DOD's personnel management system. On March 16, 2009, DOD and the Office of Personnel Management (OPM) announced an upcoming review of NSPS policies, regulations, and practices. According to DOD, the department has delayed any further transitions of employees into NSPS until at least October 2009--pending the outcome of its review. Furthermore, on May 14, 2009, the Deputy Secretary of Defense asked the Defense Business Board to form what has become this task group to review NSPS to help the department determine, among others things, whether NSPS is operating in a fair, transparent, and effective manner. This statement focuses on the performance management aspect of NSPS specifically (1) the extent to which DOD has implemented internal safeguards to ensure the fairness, effectiveness, and credibility of …

Testimony issued by the Government Accountability Office with an abstract that begins "Federal laws and policy have assigned important roles and responsibilities to the Department of Homeland Security (DHS) and the National Institute of Standards and Technology (NIST) for securing computer networks and systems. DHS is charged with coordinating the protection of computer-reliant critical infrastructure--much of which is owned by the private sector--and securing its own computer systems, while NIST is responsible for developing standards and guidelines for implementing security controls over information and information systems. GAO was asked to describe cybersecurity efforts at DHS and NIST--including partnership activities with the private sector--and the use of cybersecurity performance metrics in the federal government. To do so, GAO relied on its reports on federal information security and federal efforts to fulfill national cybersecurity responsibilities."

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security's (DHS) Domestic Nuclear Detection Office (DNDO) is responsible for addressing the threat of nuclear smuggling. Radiation detection portal monitors are key elements in the nation's defenses against such threats. DHS has sponsored testing to develop new monitors, known as advanced spectroscopic portal (ASP) monitors, to replace radiation detection equipment being used at ports of entry. DNDO expects that ASPs may offer improvements over current-generation portal monitors, particularly the potential to identify as well as detect radioactive material and thereby to reduce both the risk of missed threats and the rate of innocent alarms, which DNDO considers to be key limitations of radiation detection equipment currently used by Customs and Border Protection (CBP) at U.S. ports of entry. However, ASPs cost significantly more than current generation portal monitors. Due to concerns about ASPs' cost and performance, Congress has required that the Secretary of Homeland Security certify that ASPs provide a significant increase in operational effectiveness before obligating funds for full-scale ASP procurement. This testimony addresses (1) GAO findings on DNDO's latest round of ASP testing, and (2) lessons from ASP testing that can be …

Testimony issued by the Government Accountability Office with an abstract that begins "Recent cases of corporate fraud and mismanagement heighten the Department of Justice's (DOJ) need to appropriately punish and deter corporate crime. Recently, DOJ has made more use of deferred prosecution and non-prosecution agreements (DPAs and NPAs), in which prosecutors may require company reform, among other things, in exchange for deferring prosecution, and may also require companies to hire an independent monitor to oversee compliance. This testimony provides preliminary observations on (1) factors DOJ considers when deciding whether to enter into a DPA or NPA and setting the terms of the agreements, (2) methods DOJ uses to oversee companies' compliance, (3) processes by which monitors are selected, and (4) companies' perspectives regarding the costs and role of the monitor. It also includes the results of GAO's recently completed work on DOJ's efforts to document the monitor selection process (discussed in objective 3). GAO reviewed DOJ guidance and 57 of the 140 agreements negotiated from 1993 (when the first 2 were signed) through May 2009; and interviewed DOJ officials, officials from 17 companies, and 6 monitors. While not generalizable, these results provide insight into decisions about DPAs and NPAs."

Testimony issued by the Government Accountability Office with an abstract that begins "The Highway Account within the Highway Trust Fund (HTF) is the principal means for funding federal highway programs. Administered by the Federal Highway Administration (FHWA) within the Department of Transportation (DOT), it channels about $33 billion in highway user excise taxes annually to states for highway and related spending. Estimated outlays from the Highway Account under the Safe, Accountable, Flexible, Efficient Transportation Equity Act--A Legacy for Users (SAFETEA-LU) exceeded estimated receipts throughout the authorization period--fiscal years 2005 through 2009. Furthermore, actual account receipts were lower than had been estimated and the account balance dropped more rapidly than anticipated, approaching zero in August, 2008. Congress subsequently approved legislation in September 2008 to appropriate $8 billion from the General Fund of the Treasury to replenish the account. Agency officials anticipate the account will reach a critical stage again before the end of fiscal year 2009, and estimate that about $15 billion will be needed to ensure account solvency through the end of fiscal year 2010. This statement summarizes GAO's past work on 1) the collection and distribution process for the Highway Account of the HTF, 2) options for improving long-term …

A letter report issued by the Government Accountability Office with an abstract that begins "In its role as the nation's tax collector, the Internal Revenue Service (IRS) has a demanding responsibility to annually collect trillions of dollars in taxes, process hundreds of millions of tax and information returns, and enforce the nation's tax laws. Since its first audit of IRS's financial statements in fiscal year 1992, GAO has identified a number of weaknesses in IRS's financial management operations. In related reports, GAO has recommended corrective actions to address those weaknesses. Each year, as part of the annual audit of IRS's financial statements, GAO makes recommendations to address any new weaknesses identified and follows up on the status of IRS's efforts to address the weaknesses GAO identified in previous years' audits. The purpose of this report is to (1) provide the status of audit recommendations and actions needed to fully address them and (2) demonstrate how the recommendations relate to control activities central to IRS's mission and goals."

Correspondence issued by the Government Accountability Office with an abstract that begins "The purpose of this letter is to respond to Congressional request for information regarding the test and evaluation process conducted by the Department of Defense (DOD) of a specific synthetic lubricant called MILITEC-1 that is produced by Militec, Inc., and the assignment and cancellation of national stock numbers2 (NSN) associated with that product. Militec, Inc., has challenged DOD decisions not to include MILITEC-1 in the federal supply system. Specifically, we examined (1) the extent to which the military services have tested and evaluated MILITEC-1 as a small arms lubricant, as a metal conditioner, as a general purpose lubricant, and as a lubricant additive, and with what results; and (2) the extent to which the Defense Logistics Agency (DLA) followed applicable DOD procedures in assigning and subsequently canceling national stock numbers to MILITEC-1. In addition, we are providing in enclosure I a timeline on the efforts to test and evaluate, and assign and cancel, NSNs for MILITEC-1. MILITEC-1 is a dry, impregnated, synthetic-based metal conditioner that, at the time of our review, has been primarily marketed as a small arms lubricant, although it is also marketed as an automotive …

The Energy Independence and Security Act of 2007 (EISA) significantly expanded the renewable fuel standard (RFS) established in the Energy Policy Act of 2005. EISA requires an increasing amount of the 36 billion gallons of renewable fuel by 2022 mandate be met with "advanced biofuels." This report defines the classification "biofuels," discusses the ongoing debate regarding several aspects of biofuels endeavors, and discusses related legislative efforts on climate change policy and low-carbon fuel standards.

We present a new supernode-based incomplete LU factorization method to construct a preconditioner for solving sparse linear systems with iterative methods. The new algorithm is primarily based on the ILUTP approach by Saad, and we incorporate a number of techniques to improve the robustness and performance of the traditional ILUTP method. These include the new dropping strategies that accommodate the use of supernodal structures in the factored matrix. We present numerical experiments to demonstrate that our new method is competitive with the other ILU approaches and is well suited for today's high performance architectures.

We reported that we were successful in our 45nm technology node device demonstration in February 2008 and 22nm node technology node device patterning in February 2009 using ASML's Alpha Demo Tool (ADT). In order to insert extreme ultraviolet (EUV) lithography at the 15nm technology node and beyond, we have thoroughly characterized one EUV mask, a so-called NOVACD mask. In this paper, we report on three topics, The first topic is an analysis of line edge roughness (LER) using a mask Scanning Electron Microscope (SEM), an Atomic Force Microscope (AFM) and the Actinic Inspection Tool (AIT) to compare resist images printed with the ASML ADT. The results of the analysis show a good correlation between the mask AFM and the mask SEM measurements, However, the resist printing results for the isolated space patterns are slightly different. The cause ofthis discrepancy may be resist blur, image log slope and SEM image quality and so on. The second topic is an analysis of mask topography using an AFM and relative reflectivity of mirror and absorber surface using the AIT, The AFM data show 6 and 7 angstrom rms roughness for mirror and absorber, respectively. The reflectivity measurements show that the mirror reflects EUV …

The light curves produced by all-sky monitors, such as the Rossi X-ray Timing Explorer All-Sky Monitor and the Swift Burst Alert Telescope (BAT), generally have non-uniform error bars. In searching for periodic modulation in this type of data using power spectra it can be important to use appropriate weighting of data points to achieve the best sensitivity. It was recently demonstrated that for Swift BAT data a simple weighting scheme can actually sometimes reduce the sensitivity of the power spectrum depending on source brightness. Instead, a modified weighting scheme, based on the Cochran semi-weighted mean, gives improved results independent of source brightness. We investigate the benefits of weighting power spectra in period searches using simulated GLAST LAT observations of {gamma}-ray binaries.

The authors present recent measurements of the CKM angle {alpha} using data collected by the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at the SLAC National Accelerator Laboratory, operating at the {Upsilon}(4S) resonance. They present constraints on {alpha} from B {yields} {pi}{pi}, B {yields} {rho}{rho} and B {yields} {rho}{pi} decays.

Large fuel casks subjected to the combined loads of closure bolt tightening, internal pressure and sequential dynamic impacts present challenges when evaluating their performance in the Hypothetical Accident Conditions (HAC) specified in the Code of Federal Regulations Title 10 Part 71 (10CFR71). Testing is often limited by cost, difficulty in preparing test units and the limited availability of facilities which can carry out such tests. In the past, many casks were evaluated without testing by using simplified analytical methods. In addition, there are no realistic analyses of closure bolt stresses for HAC conditions reported in the open literature. This paper presents a numerical technique for analyzing the accumulated damages of a large fuel cask caused by the sequential loads of the closure bolt tightening and the internal pressure as well as the drop and crash dynamic loads. The bolt preload and the internal pressure are treated as quasi-static loads so that the finite element method with explicit numerical integration scheme based on the theory of wave propagation can be applied. The dynamic impacts with short durations such as the 30-foot drop and the 40-inch puncture for the hypothetical accident conditions specified in 10CFR71 are also analyzed by using the finite-element …

This paper seeks to explore some of the effects of passivating a LaNi{sub 4.25}Al{sub 0.75} sample by air oxidation under controlled conditions. Passivation of this metal hydride alloy seems to have two distinct regimes. The first occurs with air oxidation at 80 C and 20 C. It is characterized by complete reversibility upon hydrogen readsorption, although said readsorption is hindered substantially at room temperature, requiring the material to be heated to produce the reactivation. The second regime is illustrated by 130 C air oxidation and is characterized by irreversible loss of hydrogen absorption capacity. This passivation does not hinder hydrogen readsorption into the remaining hydride material.
