Large area silicon sheet by EFG. Annual progress report, October 1, 1978-September 30, 1979
The progress which has been made in 1978/1979 to evolve systems designs for growth stations which produce multiple silicon ribbons by the EFG process is reported. This progress culminated in the demonstration of five ribbon multiple growth in May 1979 and in recent advances toward improved electronic quality of ribbons grown from these machines. These advances were made in large measure by studies in which the composition of the gas environment around the meniscus area was varied. By introducing gases such as CO/sub 2/, CO, and CH/sub 4/ into this region, reproducible increases in diffusion length and cell performance have been realized, with the best large area (5 cm x 10 cm) cells exceeding 11% (AM1) efficiency.

OTEC cold water pipe design for problems caused by vortex-excited oscillations
Vortex-excited oscillations of marine structures result in reduced fatigue life, large hydrodynamic forces and induced stresses, and sometimes lead to structural damage and to diestructive failures. The cold water pipe of an OTEC plant is nominally a bluff, flexible cylinder with a large aspect ratio (L/D = length/diameter), and is likely to be susceptible to resonant vortex-excited oscillations. The objective of this report is to survey recent results pertaining to the vortex-excited oscillations of structures in general and to consider the application of these findings to the design of the OTEC cold water pipe. Practical design calculations are given as examples throughout the various sections of the report. This report is limited in scope to the problems of vortex shedding from bluff, flexible structures in steady currents and the resulting vortex-excited oscillations. The effects of flow non-uniformities, surface roughness of the cylinder, and inclination to the incident flow are considered in addition to the case of a smooth cyliner in a uniform stream. Emphasis is placed upon design procedures, hydrodynamic coefficients applicable in practice, and the specification of structural response parameters relevant to the OTEC cold water pipe. There are important problems associated with in shedding of vortices from cylinders …

Concentrations of dissolved methane (CH sub 4 ) and nitrogen (N sub 2 ) in groundwaters from the Hanford Site, Washington
This document reports all available dissolved gas concentration data for groundwaters from the Hanford Site as of June 1985. Details of the computational procedures required to reduce data obtained from the field measurements made by the Basalt Waste Isolation Project are provided in the appendix. Most measured values for methane concentration from reference repository boreholes are in the range of from 350 to 700 mg/L for the Cohassett flow top. Because of the uncertainties associated with these measurements, it is currently recommended that a conservative methane concentration of 1200 mg/L (methane saturated) in groundwater be considered the most reasonable upper-bounding value. 16 refs., 2 figs., 2 tabs.

Air Force Assessment of the Joint Strike Fighter's Aerial Refueling Method
Correspondence issued by the Government Accountability Office with an abstract that begins "The Joint Strike Fighter (JSF) acquisition program is estimated to cost $245 billion to develop and produce three variants of stealthy fighter aircraft--a conventional takeoff and landing variant for the Air Force, an aircraft carrier variant for the Navy, and a short take-off and vertical landing variant for the Marine Corps and Air Force. A major goal of the JSF program is to reduce costs by maximizing commonality among variants. However, the Air Force conventional variant is being designed with a different aerial refueling method than those used by the two other JSF variants. U.S. fighters use two different methods for aerial refueling. Air Force fixed-wing aircraft are all currently fueled by a boom that extends from a tanker aircraft and is guided into a receptacle. The Navy and Marine Corps fighters use a probe that extends from the fighter to receive fuel when inserted into a drogue, which is a basket-like device on the end of a hose that extends from the tanker. The Senate Armed Services Committee directed that we (1) examine the rationale behind the Air Force refueling decision for its JSF version, (2) determine …

Homeland Security: Voluntary Initiatives Are Under Way at Chemical Facilities, but the Extent of Security Preparedness Is Unknown
A letter report issued by the General Accounting Office with an abstract that begins "The events of September 11, 2001, triggered a national re-examination of the security of thousands of industrial facilities that use or store hazardous chemicals in quantities that could potentially put large numbers of Americans at risk of serious injury or death in the event of a terrorist-caused chemical release. GAO was asked to examine (1) available information on the threats and risks from terrorism faced by U.S. chemical facilities; (2) federal requirements for security preparedness and safety at facilities; (3) actions taken by federal agencies to assess the vulnerability of the industry; and (4) voluntary actions the chemical industry has taken to address security preparedness, and the challenges it faces in protecting its assets and operations."

Governmentwide Purchase Cards: Actions Needed to Strengthen Internal Controls to Reduce Fraudulent, Improper, and Abusive Purchases
A letter report issued by the Government Accountability Office with an abstract that begins "Over the past several years, GAO has issued numerous reports and testimonies on internal control breakdowns in certain individual agencies' purchase card programs. In light of these findings, GAO was asked to analyze purchase card transactions governmentwide to (1) determine whether internal control weaknesses existed in the government purchase card program and (2) if so, identify examples of fraudulent, improper, and abusive activity. GAO used statistical sampling to systematically test internal controls and data mining procedures to identify fraudulent, improper, and abusive activity. GAO's work was not designed to determine the overall extent of fraudulent, improper, or abusive transactions."

Lead In Tap Water: CDC Public Health Communications Need Improvement
A letter report issued by the Government Accountability Office with an abstract that begins "In February 2004, the Centers for Disease Control and Prevention (CDC) was asked to assess the effects of elevated lead levels in tap water on Washington, D.C., residents. In April 2004, CDC published the results. However, an inaccurate statement and incomplete descriptions of the limitations of the analyses resulted in confusion about CDC's intended message. GAO was asked to examine (1) CDC's actions to clarify its published results and communicate current knowledge about the contribution of lead in tap water to elevated blood lead levels (BLL) in children and (2) CDC's changes to its procedures to improve the clarity of the information in its public health communications. GAO reviewed CDC communication policies and procedures and interviewed CDC officials."

Puerto Rico: Characteristics of the Island's Maritime Trade and Potential Effects of Modifying the Jones Act
A letter report issued by the Government Accountability Office with an abstract that begins "Jones Act requirements have resulted in a discrete shipping market between Puerto Rico and the United States. Most of the cargo shipped between the United States and Puerto Rico is carried by four Jones Act carriers that provide dedicated, scheduled weekly service using containerships and container barges. Although some vessels are operating beyond their expected useful service life, many have been reconstructed or refurbished. Jones Act dry and liquid bulkcargo vessels also operate in the market, although some shippers report that qualified bulk-cargo vessels may not always be available to meet their needs. Cargo moving between Puerto Rico and foreign destinations is carried by numerous foreign-flag vessels, often with greater capacity, and typically as part of longer global trade routes. Freight rates are determined by a number of factors, including the supply of vessels and consumer demand in the market, as well as costs that carriers face to operate, some of which (e.g., crew costs) are affected by Jones Act requirements. The average freight rates of the four major Jones Act carriers in this market were lower in 2010 than they were in 2006, which was …

Department of Transportation: Key Issues and Management Challenges, 2013
Testimony issued by the Government Accountability Office with an abstract that begins "Leveraging surface transportation investments to further national interests: The Department of Transportation (DOT) faces several challenges leveraging investment in surface transportation networks to meet national goals and priorities. For example, DOT has to transition to a goal-oriented, performance-based approach for highway and transit programs, as required by the Moving Ahead for Progress in the 21st Century Act (MAP-21). Successfully implementing a performance-based approach entails new responsibilities for DOT since, as GAO has previously reported, its program oversight has generally been process-oriented rather than outcome-oriented. DOT also faces challenges related to targeting funds to priorities like the nation's freight network, effectively managing discretionary grant and credit assistance programs, and effectively overseeing other programs, such as the federal-aid highway program."

Tactical Aircraft: DOD Should Reconsider Decision to Increase F/A-22 Production Rates While Development Risks Continue
A letter report issued by the General Accounting Office with an abstract that begins "The Air Force is developing the F/A-22 aircraft to fly at higher speeds for longer distances, be less detectable, and improve the pilot's awareness of the surrounding situation. The F/A-22 will replace the Air Force's existing fleet of F-15 aircraft. Over the past several years the program has experienced significant cost overruns and schedule delays. Congress mandated that GAO assess the development program and determine whether the Air Force is meeting key performance, schedule, and cost goals. GAO also assessed the implications of the progress of the development program on production."

Combating Nuclear Smuggling: DHS's Decision to Procure and Deploy the Next Generation of Radiation Detection Equipment Is Not Supported by Its Cost-Benefit Analysis
Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) is responsible for addressing the threat of nuclear smuggling. Radiation detection portal monitors are key elements in our national defenses against such threats. DHS has sponsored R&D and testing activities to develop a "next generation" portal monitor, known as the advanced spectroscopic portal monitor. However, each one costs 6 times more than a current portal monitor. In March 2006, we recommended that DHS conduct a cost-benefit analysis to determine whether the new portal monitors are worth the additional cost. In June 2006, DHS issued its analysis. In October 2006, we issued our report that assessed the DHS study. GAO's statement, based on our October 2006 report, addresses whether DHS's cost-benefit analysis provides an adequate basis for its decision to purchase and deploy the next generation portal monitors."

Department of Housing and Urban Development: Opportunities to Improve Management of Mortgage Insurance and Rental Assistance Programs
Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Housing and Urban Development's (HUD) Federal Housing Administration (FHA) faces financial and risk-management challenges. For the fourth straight year, capital reserves for FHA's Mutual Mortgage Insurance Fund are below the statutory minimum. Also, declining balances in the fund's capital reserve account have heightened the possibility that FHA will require additional funds to have sufficient reserves for all future insurance claims on its existing portfolio. Further actions could help to restore FHA's financial soundness. For example, GAO previously concluded that Congress or HUD needs to determine the economic conditions the fund would be expected to withstand without drawing on Department of the Treasury funding. With regard to risk management, FHA has made or plans improvements. For example, FHA implemented an initiative in 2009 to strengthen internal controls and risk assessment for single-family housing and created a risk office in 2010. However, FHA has only recently begun to integrate these activities and conduct annual risk assessments in accordance with HUD guidance. Without integrated and updated risk assessments that identify emerging risks, as GAO recommended, FHA lacks assurance that it has identified all its risks."

Information Technology: Customs Automated Commercial Environment Program Progressing, but Need for Management Improvements Continues
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) is conducting a multiyear, multibillion-dollar acquisition of a new trade processing system, planned to support the movement of legitimate imports and exports and strengthen border security. By congressional mandate, plans for expenditure of appropriated funds on this system, the Automated Commercial Environment (ACE), must meet certain conditions, including GAO review. This study addresses whether the fiscal year 2005 plan satisfies these conditions, describes the status of DHS's efforts to implement prior GAO recommendations for improving ACE management, and provides observations about the plan and DHS's management of the program."

Regional Missile Defense: DOD's Report Provided Limited Information; Assessment of Acquisition Risks is Optimistic
Correspondence issued by the Government Accountability Office with an abstract that begins "The Department of Defense's (DOD) statutorily-mandated report on Regional Ballistic Missile Defense generally described plans and processes for regional missile defense. However, for the topics Congress required DOD to address, DOD has more comprehensive information which it could have provided to better reflect its current efforts and activities and which would benefit the congressional defense committees during their authorization and appropriation deliberations. One of these topics is a description of progress in system development and testing for the European Phased Adaptive Approach (a 2009 Presidential policy known as EPAA) and an assessment of technical and schedule risk. DOD's report characterizes technical and schedule risks as being minimized; based on GAO's body of work on missile defense, that characterization is optimistic."

Defense Acquisitions: Improved Business Case Is Needed for Future Combat System's Successful Outcome
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) anticipates that the Future Combat System (FCS) will modernize the U.S. Army's ability to move, shoot, and communicate on the battlefield. It is an impressive concept that is the product of holistic, non-traditional thinking. The Army describes FCS as one of the most complex weapon acquisition programs ever executed because it involves developing and integrating a family of 18 systems and an information network. Army leadership started the program early as part of its effort to change Army culture and believes that the program risks are manageable. GAO is required by law to review the program annually. In this report, GAO analyzes FCS's acquisition business case and assesses requirements stability, technology maturity, soundness of the acquisition strategy, and reasonableness and affordability of program costs."

Border Security: DHS's Progress and Challenges in Securing U.S. Borders
Testimony issued by the Government Accountability Office with an abstract that begins "U.S. Customs and Border Protection (CBP), part of the Department of Homeland Security (DHS), has reported progress in stemming illegal cross-border activity, but it could strengthen the assessment of its efforts. For example, since fiscal year 2011, DHS has used the number of apprehensions on the southwest border between ports of entry (POE) as an interim measure for border security. GAO reported in December 2012 that apprehensions decreased across the southwest border from fiscal years 2006 to 2011, which generally mirrored a decrease in estimated known illegal entries in each southwest border sector. CBP attributed this decrease in part to changes in the U.S. economy and increased resources for border security. Data reported by CBP's Office of Border Patrol (Border Patrol) show that total apprehensions across the southwest border increased from over 327,000 in fiscal year 2011 to about 357,000 in fiscal year 2012. It is too early to assess whether this increase indicates a change in the trend. GAO reported in December 2012 that the number of apprehensions provides information on activity levels but does not inform program results or resource allocation decisions. Border Patrol is in …

Critical Infrastructure Protection: Preliminary Observations on DHS Efforts to Assess Chemical Security Risk and Gather Feedback on Facility Outreach
Testimony issued by the Government Accountability Office with an abstract that begins "Since 2007, the Department of Homeland Securitys (DHS) Infrastructure Security Compliance Division (ISCD) has assigned about 3,500 high-risk chemical facilities to risk-based tiers under its Chemical Facilities Anti-Terrorism Standards (CFATS) program, but it has not fully assessed its approach for doing so. The approach ISCD used to assess risk and make decisions to place facilities in final tiers does not consider all of the elements of consequence, threat, and vulnerability associated with a terrorist attack involving certain chemicals. For example, the risk assessment approach is based primarily on consequences arising from human casualties, but does not consider economic consequences, as called for by the National Infrastructure Protection Plan (NIPP) and the CFATS regulation, nor does it include vulnerability, consistent with the NIPP. ISCD has begun to take some actions to examine how its risk assessment approach can be enhanced. Specifically, ISCD has, among other things, engaged Sandia National Laboratories to examine how economic consequences can be incorporated into ISCD's risk assessment approach and commissioned a panel of experts to assess the current approach, identify strengths and weaknesses, and recommend improvements. Given the critical nature of ISCD's risk assessment …
