Scientific data centers comprised of high-powered computing equipment and large capacity disk storage systems consume considerable amount of energy. Dynamic power management techniques (DPM) are commonly used for saving energy in disk systems. These involve powering down disks that exhibit long idle periods and placing them in standby mode. A file request from a disk in standby mode will incur both energy and performance penalties as it takes energy (and time) to spin up the disk before it can serve a file. For this reason, DPM has to make decisions as to when to transition the disk into standby mode such that the energy saved is greater than the energy needed to spin it up again and the performance penalty is tolerable. The length of the idle period until the DPM decides to power down a disk is called idlenessthreshold. In this paper, we study both analytically and experimentally dynamic power management techniques that save energy subject to performance constraints on file access costs. Based on observed workloads of scientific applications and disk characteristics, we provide a methodology for determining file assignment to disks and computing idleness thresholds that result in significant improvements to the energy saved by existing DPMsolutions …

The U.S. Department of Energy plans to vitrify both high-level and low-activity waste at the Hanford Site in southeastern Washington State. One aspect of the planning includes a need for a caustic recycle process to separate sodium hydroxide for recycle. Sodium is already a major limitation to the waste-oxide loading in the low-activity waste glass to be vitrified at the Waste Treatment Plant, and additional sodium hydroxide will be added to remove aluminum and to control precipitation in the process equipment. Aluminum is being removed from the high level sludge to reduce the number of high level waste canisters produced. A sodium recycle process would reduce the volume of low-activity waste glass produced and minimize the need to purchase new sodium hydroxide, so there is a renewed interest in investigating sodium recycle. This document describes an electrochemical facility for recycling sodium for the WTP.

Testimony issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) tax filing season performance is a key indicator of how well IRS serves taxpayers. This year's filing season was expected to be risky because of tax system changes, including the telephone excise tax refund (TETR) which can be requested by all individuals and entities that paid the excise tax. GAO was asked to describe IRS's service to taxpayers so far this filing season (including the impact of this year's tax systems changes). GAO was also asked to provide updates of previous assessments of the performance of paid tax preparers, IRS's efforts to modernize its information systems, and what IRS is doing to better measure taxpayer compliance. GAO compared IRS's filing season performance to prior years' and goals and based analyses of paid preparers, information systems, and compliance research efforts on recent reports."

Nine new CERCLA groundwater monitoring wells were installed in the 300-FF-5 Operable Unit in calendar year 2006 to fulfill commitments for the EM-20 funded polyphosphate treatability test. Nine new performance monitoring wells were drilled into the uppermost unconfined aquifer, to the Hanford formation - Ringold Formation contact boundary, and completed within the permeable Hanford fm. unit 1 gravel-dominated sequence. The overall objective of the polyphosphate treatability test is to evaluate the efficacy of using polyphosphate injections to treat 300 Area uranium contaminated groundwater in situ. The objective of this work was to install the performance monitoring network surrounding the existing treatability injection well C5000 (399-1-23) in support of the implementation of a field scale demonstration of the polyphosphate technology.

A letter report issued by the Government Accountability Office with an abstract that begins "In forming the Department of Homeland Security (DHS), there was concern that moving the U.S. Customs Service into the new DHS would diminish attention given to collection of customs revenue. In recognition of that concern, Congress required that DHS's Customs Border Protection (CBP) not reduce the staff or resources for customs revenue functions. In March 2003, CBP reported a baseline of 2,263 staff in nine customs revenue positions, and 1,006 staff in associated support positions. The SAFE Port Act required GAO to report on changes related to customs revenue functions since the formation of DHS. This report discusses staff resources, strategic workforce planning, and CBP's public reporting on customs revenue functions. GAO analyzed the number of customs revenue staff, legislatively required staffing levels, and strategic plans and annual performance reports."

A letter report issued by the Government Accountability Office with an abstract that begins "Over 3 years ago, Congress granted limited acquisition authority (LAA)--subject to delegation by the Secretary of Defense--to U.S. Joint Forces Command (JFCOM) for a 3-year period to expedite development and acquisition of certain warfighter equipment. Congress directed GAO to report on JFCOM LAA implementation. GAO's report, issued in November 2005, said JFCOM finished five LAA projects and was working on a sixth project, and that JFCOM had experienced difficulty finding funding to develop, acquire, and sustain LAA projects. Last year, Congress extended LAA through September 2008 and again directed GAO to report on LAA. This report updates the status of JFCOM LAA efforts since the authority was enacted and key LAA challenges."

This report presents the final hazard categorization (FHC) for the remediation of the 118-D-1, 118-D-2, and 118-D-3 Burial Grounds located within the 100-D/DR Area of the Hanford Site and the 118-H-1, 118-H-2, and 118-H-3 Burial Grounds located within the 100-H Area of the Hanford Site.

This paper describes a finite element analysis to predict the JNES/NUPEC cyclic and shaking table RC shear wall test data, as part of a collaborative agreement between the U.S. NRC and JNES to study seismic issues important to the safe operation of commercial nuclear power plant (NPP) structures, systems and components (SSC). The analyses described in this paper were performed using ANACAP reinforced concrete models. The paper describes the ANACAP analysis models and discusses the analysis comparisons with the test data. The ANACAP capability for modeling nonlinear cyclic characteristics of reinforced concrete shear wall structures was confirmed by the close comparisons between the ANACAP analysis results and the JNES/NUPEC cyclic test data. Reasonable agreement between the analysis results and the test data was demonstrated for the hysteresis loops and the shear force orbits, in terms of both the overall shape and the cycle-to-cycle comparisons. The ANACAP simulation analysis of the JNES/NUPEC shaking table test was also performed, which demonstrated that the ANACAP dynamic analysis with concrete material model is able to capture the progressive degrading behavior of the shear wall as indicated from the test data. The ANACAP analysis also predicted the incipient failure of the shear wall, reasonably close …

Testimony issued by the Government Accountability Office with an abstract that begins "The size and scope of the devastation caused by the 2005 Gulf Coast hurricanes presents unprecedented rebuilding challenges. Today, more than a year and a half since the hurricanes made landfall, rebuilding efforts are at a critical turning point. The Gulf Coast must face the daunting challenge of rebuilding its communities and neighborhoods--some from the ground up. This testimony (1) places the federal assistance provided to date in the context of the resources likely needed to rebuild the Gulf Coast, (2) discusses key federal programs currently being used to provide rebuilding assistance, with an emphasis on the Department of Housing and Urban Development's (HUD) Community Development Block Grant (CDBG) program, (3) describes Louisiana's and Mississippi's approach to using CDBG funds, and (4) provides observations on planning activities in Louisiana and Mississippi and the federal government's role in coordinating rebuilding efforts. GAO visited the Gulf Coast region, reviewed state and local documents, and interviewed federal, state, and local officials."

Testimony issued by the Government Accountability Office with an abstract that begins "In response to Hurricane Katrina, the Departments of Homeland Security (DHS) and Defense (DOD), the General Services Administration (GSA), and the U.S. Army Corps of Engineers (Corps) were responsible for over 90 percent of the federal funds awarded for relief efforts via contracting as of March 2007. GAO initiated work and completed a report under the Comptroller General's authority last month describing the extent to which small businesses participated in these contracting opportunities. This testimony, which summarizes information from that report, discusses (1) the amounts that small and local businesses received directly from contracts with DHS, GSA, DOD, and the Corps for relief and recovery efforts related to Hurricane Katrina and (2) the extent to which small businesses received subcontracts for relief and recovery efforts."

Testimony issued by the Government Accountability Office with an abstract that begins "U.S. government efforts to protect and enforce intellectual property (IP) rights domestically and overseas are crucial to preventing billions of dollars in losses to U.S. industry and IP rights owners and to avoiding health and safety risks resulting from the trade in counterfeit and pirated goods. IP protection and enforcement cut across a wide range of U.S. agencies and a coordinating structure has evolved to address coordination issues. First, Congress created the interagency National Intellectual Property Rights Law Enforcement Coordination Council (NIPLECC) in 1999. Later, in October 2004, the Bush administration initiated the Strategy Targeting Organized Piracy (STOP). GAO's testimony focuses on (1) the effectiveness of NIPLECC and STOP as a coordinating structure to guide and manage U.S. government efforts; and (2) the extent to which STOP meets the criteria for an effective national strategy. This statement is based on GAO's November 2006 report (GAO-07-74), which included an assessment of STOP using criteria previously developed by GAO. In this report, we recommended that head of NIPLECC, called the IP Coordinator, in consultation with the National Security Council and relevant agencies (1) clarify in the STOP strategy how NIPLECC …

Correspondence issued by the Government Accountability Office with an abstract that begins "Oil and gas from federal lands and waters is critical to meeting the nation's energy needs, providing about 35 percent of all oil and 25 percent of all the natural gas produced in the United States in fiscal year 2005. Oil and gas companies that lease federal lands and waters agree to pay the federal government royalties on the resources extracted and produced from these leases. In 1995--a time when oil and natural gas prices were significantly lower than they are today--Congress passed the Outer Continental Shelf Deep Water Royalty Relief Act of 1995 (DWRRA), which authorized the Department of the Interior's (Interior) Minerals Management Service (MMS) to provide "royalty relief" on oil and gas produced in the deep waters of the Gulf of Mexico from leases issued from 1996 through 2000. This "royalty relief" waived or reduced the amount of royalties that companies would otherwise be obligated to pay. In implementing the DWRRA for leases sold in 1996, 1997, and 2000, MMS specified that royalty relief would only be applicable if oil and gas prices were below certain levels, known as "price thresholds," thereby protecting the government's …
