RadHeat V1 User's Manual (open access)

RadHeat V1 User's Manual

RadHeat is a one dimensional finite difference heat transfer code that can determine the transient temperature evolution of layered targets in pulsed penetrating radiation environments. It makes use of energy dependent opacity and stopping data to model the volumetric deposition of any number of photon or ion spectra each incident at arbitrary angles. Convective and radiative boundary conditions are handled as well as the ability to impose any initial temperature profile. The heat diffusion equation is formulated implicitly to eliminate timestep dependent stability issues. Simulations are, therefore, able to achieve high fidelity during times of thermal activity and greater speed elsewhere. The prototypical physical situation simulated by RadHeat is illustrated. RadHeat was originally written to study the temperature response of tungsten-armored target-facing walls to the pulsed photon and ion radiation emanating from fusion microexplosions in future IFE power plants. RadHeat's implementation is quite general, though, and the code can be applied to a very broad range of problems. Anything from the heating of the Earth's crust on a warm summer day to the temperature rise in a mirror after a laser pulse could potentially be modeled. This manual was written to help new users learn how to run the code …

Management Report: Opportunities for Improvements in FHFA's Internal Controls and Accounting Procedures

Correspondence issued by the Government Accountability Office with an abstract that begins "In November 2009, we issued our opinion on the fiscal year 2009 financial statements of the Federal Housing Finance Agency (FHFA). Our report also included our opinion on the effectiveness of FHFA's internal control over financial reporting as of September 30, 2009, and our evaluation of FHFA's compliance with provisions of selected laws and regulations for the fiscal year ended September 30, 2009. The Housing and Economic Recovery Act of 2008 (HERA) created FHFA and gave it responsibility for, among other things, the supervision and oversight of the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac), and the 12 federal home loan banks. Specifically, FHFA was assigned responsibility for ensuring that the regulated entities operate in a fiscally safe and sound manner, including maintenance of adequate capital and internal controls, in carrying out their housing and community development finance mission. HERA requires FHFA to annually prepare financial statements, and requires GAO to audit these statements. HERA established FHFA as an independent agency on July 30, 2008. HERA also abolished, effective within 1 year of the act's enactment, the Office of Federal Housing …

Medicare Part D: CMS Oversight of Part D Sponsors' Fraud and Abuse Programs Has Been Limited, but CMS Plans Oversight Expansion (open access)

Medicare Part D: CMS Oversight of Part D Sponsors' Fraud and Abuse Programs Has Been Limited, but CMS Plans Oversight Expansion

Testimony issued by the Government Accountability Office with an abstract that begins "Medicare Part D, the voluntary, outpatient prescription drug benefit for eligible individuals 65 years and older and certain individuals with disabilities, is at risk for fraud, waste, and abuse. Part D is administered by the Centers for Medicare & Medicaid Services (CMS). All Part D sponsors--private companies that operate Part D benefit plans--are required to have programs to safeguard the Part D program from fraud, waste, and abuse. GAO refers to these programs as fraud and abuse programs. This statement discusses CMS's oversight of Part D sponsors' fraud and abuse programs, including its past efforts and planned oversight activities. It is primarily based on the GAO report, Medicare Part D: Some Plan Sponsors Have Not Completely Implemented Fraud and Abuse Programs, and CMS Oversight Has Been Limited (GAO-08-760). The five Part D sponsors GAO reviewed for that report had not completely implemented all of CMS's elements for Part D fraud and abuse programs at that time. CMS agreed with GAO's recommendation in the report that it conduct timely audits of Part D sponsors' fraud and abuse programs. For the 2008 report, GAO reviewed laws, regulation, and CMS documents, …

Medicaid Financing: Long-standing Concerns about Inappropriate State Arrangements Support Need for Improved Federal Oversight

Testimony issued by the Government Accountability Office with an abstract that begins "Medicaid, a joint federal-state program, financed the health care for about 59 million low-income people in fiscal year 2006. States have considerable flexibility in deciding what medical services and individuals to cover and the amount to pay providers, and the federal government reimburses a portion of states' expenditures according to a formula established by law. The Centers for Medicare & Medicaid Services (CMS) is the federal agency responsible for overseeing Medicaid. Growing pressures on federal and state budgets have increased tensions between the federal government and states regarding this program, including concerns about whether states were appropriately financing their share of the program. GAO's testimony describes findings from prior work conducted from 1994 through March 2007 on (1) certain inappropriate state Medicaid financing arrangements and their implications for Medicaid's fiscal integrity and (2) outcomes and transparency of a CMS oversight initiative begun in 2003 to end such inappropriate arrangements."

Information Security: Weaknesses Continue Amid New Federal Efforts to Implement Requirements

A publication issued by the Government Accountability Office with an abstract that begins "For many years, GAO has reported that weaknesses in information security can lead to serious consequences--such as intrusions by malicious individuals, compromised networks, and the theft of sensitive information including personally identifiable information--and has identified information security as a governmentwide high-risk area. The Federal Information Security Management Act of 2002 (FISMA) established information security program, evaluation, and annual reporting requirements for federal agencies. The act requires the Office of Management and Budget (OMB) to oversee and report to Congress on agency information security policies and practices, including agencies' compliance with FISMA. FISMA also requires that GAO periodically report to Congress on (1) the adequacy and effectiveness of agencies' information security policies and practices and (2) agencies' implementation of FISMA requirements. To do this, GAO analyzed information security-related reports and data from 24 major federal agencies, their inspectors general, OMB, and GAO."

Internal Revenue Service: 2001 Tax Filing Season, Systems Modernization, and Security of Electronic Filing

Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses (1) the status of the 2001 tax filing season, (2) the status of the Internal Revenue Service's (IRS) business systems modernization effort, and (3) the security of IRS' electronic filing system. GAO found that although the 2001 filing season appears to be running smoothly, some matters require further attention. For example, IRS has had problems with the personal identification number assigned to electronic filers. Although data indicate that taxpayers are having an easier time reaching IRS to ask questions, concerns persist about the productivity of its telephone assistors. With respect to business systems modernization, GAO has long held that IRS needs to establish fundamental modernization management controls before it begins to build and implement modernized systems. IRS has made some progress in this area, but it is still not where it needs to be. GAO is concerned that IRS is allowing its system acquisition projects to get ahead of its capabilities for managing them. Lastly, GAO's review of IRS' electronic filing systems last year showed that IRS had ineffective controls to ensure the security of those systems and electronically-transmitted taxpayer data. IRS moved promptly to …

Federal Contracting: Application of OMB Guidance Can Improve Use of Award Fee Contracts

Testimony issued by the Government Accountability Office with an abstract that begins "From fiscal year 2004 through fiscal year 2008, agencies spent over $300 billion on contracts which include award fees. While many agencies use award fee contracts, over 95 percent of the government's spending using this contract type in fiscal year 2008 occurred at five: the departments of Defense (DOD), Energy (DOE), Health and Human Services (HHS), and Homeland Security (DHS) and the National Aeronautics and Space Administration (NASA). In December 2007, the Office of Management and Budget's (OMB) Office of Federal Procurement Policy issued guidance to chief acquisition officers and procurement executives across the government that echoed several recommendations we made in 2005 on the use of award fees and emphasized positive practices to be implemented by all agencies. GAO's statement today is based on our May 29, 2009, report, Federal Contracting: Guidance on Award Fees Has Led to Better Practices But is Not Consistently Applied (GAO-09-630). Like the report, this statement addresses how agencies are implementing OMB's guidance. Specifically, we (1) identified the actions agencies have taken to revise or develop policies and guidance to reflect OMB guidance on using award fees, (2) determined the extent to …

Nuclear Security: DOE Needs to Fully Address Issues Affecting Protective Forces' Personnel Systems

Testimony issued by the Government Accountability Office with an abstract that begins "The September 11, 2001, terrorist attacks raised concerns about the security of Department of Energy (DOE) sites with weapons-grade nuclear material, known as Category I special nuclear material (SNM). To better protect these sites against attacks, DOE has sought to transform its protective forces protecting SNM into a Tactical Response Force (TRF) with training and capabilities similar to the U.S. military. This testimony is based on prior work and has been updated with additional information provided by protective forces' union officials. In a prior GAO report, Nuclear Security: DOE Needs to Address Protective Forces' Personnel System Issues (GAO-10-275), GAO (1) analyzed information on the management, organization, staffing, training, and compensation of protective forces at DOE sites with Category I SNM; (2) examined the implementation of TRF; and (3) assessed DOE's two options to more uniformly manage protective forces; and (4) reported on DOE's progress in addressing protective force issues. DOE generally agreed with the recommendations in GAO's prior report that called for the agency to fully assess and implement, where feasible, measures identified by DOE's 2009 protective forces study group to enhance protective forces' career longevity and retirement …

Financial Institutions: Issues Regarding the Tax-Exempt Status of Credit Unions (open access)

Financial Institutions: Issues Regarding the Tax-Exempt Status of Credit Unions

Testimony issued by the Government Accountability Office with an abstract that begins "Unlike other depository institutions, credit unions are exempt from federal corporate income taxes. Recent legislative and regulatory changes to credit union membership restrictions and allowable products and services have blurred some of the historical distinctions between credit unions and other depository institutions. As a result, some observers have raised questions about whether tax exemption provides credit unions with an advantage over other depository institutions and whether the original basis for tax exemption is still valid. As part of its continuing oversight of the tax-exempt sector, the House Committee on Ways and Means asked GAO to address (1) the historical basis for the tax-exempt status of credit unions; (2) the arguments for and against taxation, including estimates of potential revenue from eliminating the exemption; (3) the extent to which credit unions offer services distinct from those offered by banks of comparable size, and serve low-and moderate-income individuals; and (4) the extent to which credit unions are required to report information on executive compensation and assessments of their internal controls."

Testimony issued by the Government Accountability Office with an abstract that begins "In November 2006, about 18,000 undervotes were reported in Sarasota County in the race for Florida's 13th Congressional District. Following the contesting of the election results in the House of Representatives, the Task Force met and unanimously voted to seek GAO's assistance in determining whether the voting systems contributed to the large undervote in Sarasota County. On June 14, 2007, we met with the Task Force and agreed upon an engagement plan, which included the following review objectives: (1) What voting systems and equipment were used in Sarasota County and what processes governed their use? (2) What was the scope of the undervote in Sarasota County in the general election? (3) To what extent were tests conducted on the voting systems in Sarasota County prior to the general election and what were the results of those tests? and (4) Considering the tests that were conducted on the voting systems from Sarasota County after the general election, are additional tests needed to determine whether the voting systems contributed to the undervote?

Correspondence issued by the Government Accountability Office with an abstract that begins "In response to a congressional mandate to assess the reasons why the Department of Defense (DOD) is not fully in compliance with the Improper Payments Information Act of 2002 (IPIA) related to DOD travel expenditures, GAO issued two reports in 2007. In May 2007, we issued an initial report that provided an overview of DOD's IPIA reporting for fiscal years 2003 through 2006 and a discussion of the reasons reported by the DOD Office of Inspector General why the department was not in compliance with IPIA for fiscal year 2006. In December 2007, we issued our final report on our assessment of the completeness and accuracy of DOD's fiscal year 2006 IPIA disclosures related to travel expenditures, as well as DOD's planned efforts to improve and refine its processes for estimating and reporting on travel improper payments.

Customs and INS: Random Inspection Programs Can Be Strengthened (open access)

Customs and INS: Random Inspection Programs Can Be Strengthened

Correspondence issued by the General Accounting Office with an abstract that begins "This report reviews the U.S. Customs Service's Compliance Measurement Examination (COMPEX) and Immigration and Naturalization Service's (INS) Inspections Traveler Examination (INTEX). These programs, which help Customs and INS assess the nature and extent of enforcement risks at ports of entry, compare violations found during targeted inspections with violations found during random inspections. GAO found that both Customs and INS inspectors did not always adhere to guidance on sample selection and did not always conduct inspections with the minimum level of thoroughness required. As a result, statistical data generated by the programs may not reliably reflect the extent to which travelers who seek entry into the U.S. are in violation of customs or immigration laws. GAO also found that the COMPEX and INTEX programs both draw from the same population of international travelers; have similar purposes and goals; and often use Customs and INS inspectors who work side by side, particularly at land border ports of entry. Customs and INS might realize efficiencies if the two programs were combined."

Testimony issued by the Government Accountability Office with an abstract that begins "Offshore tax evasion is difficult for the Internal Revenue Service (IRS) to address. IRS examines tax returns to deal with offshore evasion that has occurred. IRS's Qualified Intermediary (QI) program seeks to foster improved tax withholding and reporting. GAO was asked to testify on two topics. First, GAO was asked to provide information on (1) the length of, and assessments from, IRS's examination of tax returns with offshore activity and (2) the impact of the 3-year statute of limitations on offshore cases. Second, for the QI program, GAO was asked to address (1) program features intended to improve withholding and reporting, and (2) whether weaknesses exist in the U.S. withholding system for U.S. source income and QI external reviews and IRS's use of program data. GAO relied on prior work for the first topic. For the QI program, GAO used the latest data that were available and corroborated by IRS."
