Reporting of Small Business Contract Awards Does Not Reflect Current Business Size

Description: Correspondence issued by the General Accounting Office with an abstract that begins "We have prepared this report in response to concerns about whether large companies are receiving federal contracts intended for small businesses. We reviewed awards to five large companies to determine (1) how contracts awarded to the companies were reported in Federal Procurement Data System (FPDS), (2) why federal contract officials reported the contracts as small business awards, and (3) what actions are bei… more

VA Health Care: VA Increases Third-Party Collections as It Addresses Problems in Its Collections Operations

Description: Testimony issued by the General Accounting Office with an abstract that begins "The Department of Veterans Affairs (VA) collects health insurance payments, known as third-party collections, for veterans' health care conditions it treats that are not a result of injuries or illnesses incurred or aggravated during military service. In September 1999, VA adopted a new fee schedule, called "reasonable charges," that it anticipated would increase revenues from third-party collections. In January 200… more

SARS Outbreak: Improvements to Public Health Capacity Are Needed for Responding to Bioterrorism and Emerging Infectious Diseases

Description: Testimony issued by the General Accounting Office with an abstract that begins "SARS has infected relatively few people nationwide, but it has raised concerns about preparedness for large-scale infectious disease outbreaks. The initial response to an outbreak occurs in local agencies and hospitals, with support from state and federal agencies, and can involve disease surveillance, epidemiologic investigation, health care delivery, and quarantine management. Officials have learned lessons applic… more

Compliance and Collection: Challenges for IRS in Reversing Trends and Implementing New Initiatives

Description: Testimony issued by the General Accounting Office with an abstract that begins "Taxpayers' willingness to voluntarily comply with tax laws depends in part on their confidence that friends, neighbors, and business competitors are paying their fair share of taxes. The Internal Revenue Service's (IRS) programs to ensure compliance and to collect delinquent taxes are viewed by many as critical for maintaining the public's confidence in our tax system. Congress asked GAO to present information on tr… more

Interprocessor communication with limited memory

Description: Many parallel applications require periodic redistribution of workloads and associated data. In a distributed memory computer, this redistribution can be difficult if limited memory is available for receiving messages. We propose a model for optimizing the exchange of messages under such circumstances which we call the minimum phase remapping problem. We first show that the problem is NP-Complete, and then analyze several methodologies for addressing it. First, we show how the problem can be ph… more

SYNTHESIS AND CHARACTERIZATION OF NEW INTERMETALLIC COMPOUNDS

Description: This six-month work is focused mainly on the properties of novel magnetic intermetallics. In the first project, we synthesized several 2:17 intermetallic compounds, namely Nd{sub 2}Fe{sub 15}Si{sub 2}, Nd{sub 2}Fe{sub 15}Al{sub 2}2, Nd{sub 2}Fe{sub 15}SiAl and Nd{sub 2}Fe{sub 15}SiMn, as well as several 1:12 intermetallic compounds, such as NdFe{sub 10}Si{sub 2}, NdFe{sub 10}Al{sub 2}, NdFe{sub 10}SiAl and NdFe{sub 10}MnAl. In the second project, seven compositions of Nd{sub x}Fe{sub 100-x-y}B{… more

Time Evolution of Beam in the Recycler Ring

Description: We study the time evolution of the beam current in the Fermilab Recycler Ring due to abrupt physical processes (single coulomb scattering, nuclear scattering) that cause sudden loss of beam, and diffusive processes (multiple coulomb scattering, lattice dependence, etc.) which cause emittance growth. This emittance growth combined with finite aperture of the beam pipe will lead to eventual loss of most beam. We develop a fitting technique to the time evolution of beam current to estimate emittan… more

Stray-electron accumulation and effects in HIF accelerators

Description: Stray electrons can be introduced in positive-charge accelerators for heavy ion fusion (or other applications) as a result of ionization of ambient gas or gas released from walls due to halo-ion impact, or as a result of secondary-electron emission. Electron accumulation is impacted by the ion beam potential, accelerating fields, multipole magnetic fields used for beam focus, and the pulse duration. We highlight the distinguishing features of heavy-ion accelerators as they relate to stray-elect… more

Advanced Algorithms and Automation Tools for Discrete Ordinates Methods in Parallel Environments

Description: This final report discusses major accomplishments of a 3-year project under the DOE's NEER Program. The project has developed innovative and automated algorithms, codes, and tools for solving the discrete ordinates particle transport method efficiently in parallel environments. Using a number of benchmark and real-life problems, the performance and accuracy of the new algorithms have been measured and analyzed.

Gallium Safety in the Laboratory

Description: A university laboratory experiment for the US Department of Energy magnetic fusion research program required a simulant for liquid lithium. The simulant choices were narrowed to liquid gallium and galinstan (Ga-In-Sn) alloy. Safety information on liquid gallium and galinstan were compiled, and the choice was made to use galinstan. A laboratory safety walkthrough was performed in the fall of 2002 to support the galinstan experiment. The experiment has been operating successfully since early 2002. more

Out-of-Core Compression and Decompression of Large n-Dimensional Scalar Fields

Description: We present a simple method for compressing very large and regularly sampled scalar fields. Our method is particularly attractive when the entire data set does not fit in memory and when the sampling rate is high relative to the feature size of the scalar field in all dimensions. Although we report results for R{sup 3} and R{sup 4} data sets, the proposed approach may be applied to higher dimensions. The method is based on the new Lorenzo predictor, introduced here, which estimates the value of … more

The Performance of Parallel Disk Write Methods for Linux Multiprocessor Nodes

Description: Despite increasing attention paid to parallel I/O and the introduction of MPI-IO, there is limited, practical data to help guide a programmer in the choice of a good parallel write strategy in the absence of a parallel file system. In this study we experimentally evaluate several methods for implementing parallel computations that interleave a significant number of contiguous or strided writes to a local disk on Linux-based multiprocessor nodes. Using synthetic benchmark programs written with M… more

Full-Scale Testing of Enhanced Mercury Control Technologies for Wet FGD Systems: Final Report

Description: Wet flue gas desulfurization (wet FGD) systems are currently installed on about 25% of the coal-fired utility generating capacity in the U.S., representing about 15% of the number of coal-fired units. Depending on the effect of operating parameters such as mercury content of the coal, form of mercury (elemental or oxidized) in the flue gas, scrubber spray tower configuration, liquid-to-gas ratio, and slurry chemistry, FGD systems can provide cost-effective, near-term mercury emissions control o… more

Weapons of Mass Destruction: Trade Between North Korea and Pakistan

Description: In October 2002, the United States confronted North Korea about its alleged clandestine uranium enrichment program. Soon after, the Agreed Framework collapsed, North Korea expelled international inspectors, and withdrew from the Nuclear Nonproliferation Treaty (NPT). U.S. intelligence officials claimed Pakistan was a key supplier of uranium enrichment technology to North Korea, and some media reports suggested that Pakistan had exchanged centrifuge enrichment technology for North Korean help in… more
