2010 Census: Operational Changes Made for 2010 Position the U.S. Census Bureau to More Accurately Classify and Identify Group Quarters

Testimony issued by the Government Accountability Office with an abstract that begins "The U.S. Census Bureau (Bureau) is tasked with conducting an accurate count of people living in dwellings known as group quarters as part of the 2010 Census. Group quarters consist of college dormitories, prisons, nursing homes, and other facilities typically owned or managed by an entity providing housing, services, or both for the residents. During the 2000 Census, for a variety of reasons, group quarters were sometimes counted more than once, missed, or included in the wrong location. As requested, this testimony will focus on (1) the extent to which the Bureau has strengthened its procedures for counting group quarters compared to the 2000 Census, and (2) particular challenges and opportunities for an accurate group quarters count in Brooklyn. The testimony is based on previously issued and ongoing GAO work in New York and elsewhere."

Advance Appropriations, Forward Funding, and Advance Funding

pppropriations acts generally make budget authority (or BA) available for use (or obligation) at the start of the fiscal year covered by the act. Sometimes appropriations bills provide a different date for specified budget authority within the act to become first available so that the funding cycle does not coincide with the fiscal year generally covered by the act. There are three types of this kind of budget authority: advance appropriations, forward funding, and advance funding.

Advanced Simulation and Computing Fiscal Year 2011-2012 Implementation Plan, Revision 0 (open access)

Advanced Simulation and Computing Fiscal Year 2011-2012 Implementation Plan, Revision 0

The Stockpile Stewardship Program (SSP) is a single, highly integrated technical program for maintaining the surety and reliability of the U.S. nuclear stockpile. The SSP uses past nuclear test data along with current and future non-nuclear test data, computational modeling and simulation, and experimental facilities to advance understanding of nuclear weapons. It includes stockpile surveillance, experimental research, development and engineering (D&E) programs, and an appropriately scaled production capability to support stockpile requirements. This integrated national program requires the continued use of current facilities and programs along with new experimental facilities and computational enhancements to support these programs. The Advanced Simulation and Computing Program (ASC) is a cornerstone of the SSP, providing simulation capabilities and computational resources to support the annual stockpile assessment and certification, to study advanced nuclear weapons design and manufacturing processes, to analyze accident scenarios and weapons aging, and to provide the tools to enable stockpile Life Extension Programs (LEPs) and the resolution of Significant Finding Investigations (SFIs). This requires a balanced resource, including technical staff, hardware, simulation software, and computer science solutions. In its first decade, the ASC strategy focused on demonstrating simulation capabilities of unprecedented scale in three spatial dimensions. In its second decade, ASC is …

Alien Smuggling: DHS Could Better Address Alien Smuggling along the Southwest Border by Leveraging Investigative Resources and Measuring Program Performance

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses federal efforts to address alien smuggling along the southwest border. Alien smuggling along the southwest border is an increasing threat to the security of the United States and Mexico as well as to the safety of both law enforcement and smuggled aliens. One reason for this increased threat is the involvement of drug trafficking organizations in alien smuggling. According to the National Drug Intelligence Center's (NDIC) 2008 National Drug Threat Assessment, the southwest border region is the principal entry point for smuggled aliens from Mexico, Central America, and South America. Aliens from countries of special interest to the United States such as Afghanistan, Iran, Iraq, and Pakistan (known as special-interest aliens) also illegally enter the United States through the region. According to the NDIC assessment, Mexican drug trafficking organizations have become increasingly involved in alien smuggling. These organizations collect fees from alien smuggling organizations for the use of specific smuggling routes, and available reporting indicates that some Mexican drug trafficking organizations specialize in smuggling special-interest aliens into the United States. As a result, these organizations now have alien smuggling as an additional source of funding …

Analysis of the National Ignition Facility Ignition Hohlraum Energetics Experiments (open access)

Analysis of the National Ignition Facility Ignition Hohlraum Energetics Experiments

A series of forty experiments on the National Ignition Facility (NIF) [E. I. Moses et al., Phys. Plasmas 16, 041006 (2009)] to study energy balance and implosion symmetry in reduced- and full-scale ignition hohlraums was shot at energies up to 1.3 MJ. This paper reports the findings of the analysis of the ensemble of experimental data obtained that has produced an improved model for simulating ignition hohlraums. Last year the first observation in a NIF hohlraum of energy transfer between cones of beams as a function of wavelength shift between those cones was reported [P. Michel, et al, Phys of Plasmas, 17, 056305, (2010)]. Detailed analysis of hohlraum wall emission as measured through the laser entrance hole (LEH) has allowed the amount of energy transferred versus wavelength shift to be quantified. The change in outer beam brightness is found to be quantitatively consistent with LASNEX [G. B. Zimmerman and W. L. Kruer, Comments Plasma Phys. Control. Fusion 2, 51 (1975)] simulations using the predicted energy transfer when possible saturation of the plasma wave mediating the transfer is included. The effect of the predicted energy transfer on implosion symmetry is also found to be in good agreement with gated x-ray framing …

Army Working Capital Fund: Army Faces Challenges in Managing Working Capital Fund Cash Balance during Wartime Environment

A letter report issued by the Government Accountability Office with an abstract that begins "The Army Working Capital Fund (AWCF) collected over $16 billion for goods and services provided to customers in fiscal year 2009. Cash generated from sales is used by AWCF to cover its expenses such as paying employees. In light of the Army's changing role in the Middle East, GAO was asked to determine whether (1) AWCF's monthly cash balances fell within the Department of Defense's (DOD) cash requirements for fiscal years 2000 through 2009, (2) the cash transfers resulted in AWCF's monthly cash balances falling below the minimum amount required by DOD, and (3) the AWCF's projected monthly cash balances are expected to fall below DOD's minimum cash requirement for fiscal years 2010 and 2011 and actions the Army can take to manage those balances. To address these objectives, GAO (1) reviewed relevant DOD guidance, (2) obtained and analyzed AWCF budget and accounting reports containing cash information, and (3) interviewed DOD and Army officials."

An Assessment of the Penetrations in the First Wall Required for Plasma Measurments for Control of an Advanced Tokamak Plasma Demo (open access)

An Assessment of the Penetrations in the First Wall Required for Plasma Measurments for Control of an Advanced Tokamak Plasma Demo

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.

Atmospheric Stability Impacts on Power Curves of Tall Wind Turbines - An Analysis of a West Coast North American Wind Farm (open access)

Atmospheric Stability Impacts on Power Curves of Tall Wind Turbines - An Analysis of a West Coast North American Wind Farm

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 …

Bacillus anthracis genome organization in light of whole transcriptome sequencing (open access)

Bacillus anthracis genome organization in light of whole transcriptome sequencing

Emerging knowledge of whole prokaryotic transcriptomes could validate a number of theoretical concepts introduced in the early days of genomics. What are the rules connecting gene expression levels with sequence determinants such as quantitative scores of promoters and terminators? Are translation efficiency measures, e.g. codon adaptation index and RBS score related to gene expression? We used the whole transcriptome shotgun sequencing of a bacterial pathogen Bacillus anthracis to assess correlation of gene expression level with promoter, terminator and RBS scores, codon adaptation index, as well as with a new measure of gene translational efficiency, average translation speed. We compared computational predictions of operon topologies with the transcript borders inferred from RNA-Seq reads. Transcriptome mapping may also improve existing gene annotation. Upon assessment of accuracy of current annotation of protein-coding genes in the B. anthracis genome we have shown that the transcriptome data indicate existence of more than a hundred genes missing in the annotation though predicted by an ab initio gene finder. Interestingly, we observed that many pseudogenes possess not only a sequence with detectable coding potential but also promoters that maintain transcriptional activity.

Best Practices: DOD Can Achieve Better Outcomes by Standardizing the Way Manufacturing Risks Are Managed

A letter report issued by the Government Accountability Office with an abstract that begins "Cost growth and schedule delays are prevalent problems in acquiring defense weapon systems. Manufacturing systems has proven difficult, particularly as programs transition to production. In December 2008, the Department of Defense (DOD) issued an updated version of its acquisition policy that reflects earlier consideration of manufacturing risks. A joint defense and industry group developed manufacturing readiness levels (MRL) to support assessments of manufacturing risks. Use of MRLs on all weapon acquisition programs has been proposed. In response to a congressional request, this report assesses the manufacturing problems faced by DOD, how MRLs can address manufacturing problems, how MRLs compare to manufacturing best practices of leading commercial firms, and challenges and barriers to implementing MRLs at DOD. In conducting our work, we contacted DOD, military services, and contractors; held interviews with leading commercial firms; reviewed program documents and policy proposals; and spoke with manufacturing experts."

Biasing, Acquisition and Interpretation of a Dense Langmuir Probe Array in NSTX (open access)

Biasing, Acquisition and Interpretation of a Dense Langmuir Probe Array in NSTX

A dense array of 99 Langmuir probes has been installed in the lower divertor region of the National Spherical Torus Experiments (NSTX). This array is instrumented with a system of elec- tronics that allows flexibility in the choice of probes to bias as well as the type of measurement (including standard swept, single probe, triple probe and operation as passive floating potential and scrape-off-layer (SOL) current monitors). The use of flush-mounted probes requires careful inter- pretation. The time dependent nature of the SOL makes swept-probe traces difficult to interpret. To overcome these challenges, the single- and triple-Langmuir probe signals are used in comple- mentary fashion to determine the temperature and density at the probe location. A comparison to mid-plane measurements is made. Work is supported by DOE contracts DE-AC02-09CHI1466 and DE-PS02-07ER07-29.

Border Security: Better Usage of Electronic Passport Security Features Could Improve Fraud Detection

A letter report issued by the Government Accountability Office with an abstract that begins "In 2005, the Department of State (State) began issuing electronic passports (e-passports) with embedded computer chips that store information identical to that printed in the passport. By agreement with State, the U.S. Government Printing Office (GPO) produces blank e-passport books. Two foreign companies are used by GPO to produce e-passport covers, including the computer chips embedded in them. At U.S. ports of entry, the Department of Homeland Security (DHS) inspects passports. GAO was asked to examine potential risks to national security posed by using foreign suppliers for U.S. e-passport computer chips. This report specifically examines the following two risks: (1) Can the computer chips used in U.S. e-passports be altered or forged to fraudulently enter the United States? (2) What risk could malicious code on the U.S. e-passport computer chip pose to national security? To conduct this work, GAO reviewed documents and interviewed officials at State, GPO, and DHS relating to the U.S. e-passport design and manufacturing and e-passport inspection systems and procedures."

Building Energy Information Systems: User Case Studies

Measured energy performance data are essential to national efforts to improve building efficiency, as evidenced in recent benchmarking mandates, and in a growing body of work that indicates the value of permanent monitoring and energy information feedback. This paper presents case studies of energy information systems (EIS) at four enterprises and university campuses, focusing on the attained energy savings, and successes and challenges in technology use and integration. EIS are broadly defined as performance monitoring software, data acquisition hardware, and communication systems to store, analyze and display building energy information. Case investigations showed that the most common energy savings and instances of waste concerned scheduling errors, measurement and verification, and inefficient operations. Data quality is critical to effective EIS use, and is most challenging at the subsystem or component level, and with non-electric energy sources. Sophisticated prediction algorithms may not be well understood but can be applied quite effectively, and sites with custom benchmark models or metrics are more likely to perform analyses external to the EIS. Finally, resources and staffing were identified as a universal challenge, indicating a need to identify additional models of EIS use that extend beyond exclusive in-house use, to analysis services.

Building Security: New Federal Standards Hold Promise, But Could Be Strengthened to Better Protect Leased Space

A letter report issued by the Government Accountability Office with an abstract that begins "The federal government's reliance on leased space underscores the need to physically secure this space and help safeguard employees, visitors, and government assets. In April 2010 the Interagency Security Committee (ISC), comprised of 47 federal agencies and departments and chaired by the Department of Homeland Security (DHS), issued Physical Security Criteria for Federal Facilities (the 2010 standards) which supersede previous ISC standards. In response to Congress' direction to review ISC standards for leased space, this report (1) identifies challenges that exist in protecting leased space and (2) examines how the 2010 standards address these challenges. To conduct this work, GAO analyzed agency documents and interviewed federal officials from ISC, four federal departments selected as case studies based on their large square footage of leased space, and the Federal Protective Service (FPS). GAO also consulted prior work on federal real property and physical security, including key practices in facility protection."
