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

Description: 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 assig… more

Financial Management: Internal Control Weaknesses Leave Department of Education Vulnerable to Improper Payments

Description: Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses internal control weaknesses in the Department of Education's payment process. GAO identified internal control weaknesses that sharply increase Education's vulnerability to improper payments. GAO classified the weaknesses into the following four broad categories: (1) poor segregation of duties, (2) lack of supervisory review, (3) inadequate audit trails, and (4) inadequate computer systems' a… more

The Novel Synthesis of Silicon and Germanium Nanocrystallites

Description: Interest in the synthesis of semiconductor nanoparticles has been generated by their unusual optical and electronic properties arising from quantum confinement effects. We have synthesized silicon and germanium nanoclusters by reacting Zintl phase precursors with either silicon or germanium tetrachloride in various solvents. Strategies have been investigated to stabilize the surface, including reactions with RLi and MgBrR (R = alkyl). This synthetic method produces group IV nanocrystals with pa… more

Microstructure of laterally overgrown GaN layers

Description: Transmission electron microscopy study of plan-view and cross-section samples of epitaxial laterally overgrown (ELOG) GaN samples is described. Two types of dislocation with the same type of Burgers vector but different line direction have been observed. It is shown that threading edge dislocations bend to form dislocation segments in the c-plane as a result of shear stresses developed in the wing material along the stripe direction. It is shown that migration of these dislocations involves bot… more

Understanding Carbon Sequestration Options in the United States: Capabilities of a Carbon Management Geographic Information System

Description: While one can discuss various sequestration options at a national or global level, the actual carbon management approach is highly site specific. In response to the need for a better understanding of carbon management options, Battelle in collaboration with Mitsubishi Corporation, has developed a state-of-the-art Geographic Information System (GIS) focused on carbon capture and sequestration opportunities in the United States. The GIS system contains information (e.g., fuel type, location, vint… more

Laboratory and Field Measurements of Electrical Resistivity to Determine Saturation and Detect Fractures in a Heated Rock Mass

Description: Laboratory measurements of the electrical resistivity of intact and fractured representative geothermal reservoir rocks were performed to investigate the resistivity contrast caused by active boiling and to infer saturation and fracture location in a large-scale field test. Measurements were performed to simulate test conditions with confining pressures up to 100 bars and temperatures to 145 C. Measurements presented are a first step toward making the search for fractures using electrical metho… more

Detailed Hydrodynamic and X-Ray Spectroscopic Analysis of a Laser-Produced Rapidly-Expanding Aluminum Plasma

Description: We present a detailed analysis of K-shell emission from laser-produced rapidly-expanding aluminum plasmas. This work forms part of a series of experiments performed at the Vulcan laser facility of the Rutherford Appleton Laboratory, UK. 1-D planar expansion was obtained by over-illuminating Al-microdot targets supported on CH plastic foils. The small size of the Al-plasma ensured high spatial and frequency resolution of the spectra, obtained with a single crystal spectrometer, two vertical disp… more

Prevention of Reservoir Interior Discoloration

Description: Contamination is anathema in reservoir production. Some of the contamination is a result of welding and some appears after welding but existed before. Oxygen was documented to be a major contributor to discoloration in welding. This study demonstrates that it can be controlled and that some of the informal cleaning processes contribute to contamination.

Process Development and Basic Studies of Electrochemically Deposited CdTe-Based Solar Cells; Annual Technical Report, Phase II, 16 May 1999-13 May 2000

Description: This project, carried out at the Colorado School of Mines, addresses long-term research and development issues related to polycrystalline thin-film solar cells. Our general research approach is based on combining activities aimed at improving cell performance and stability with activities aimed at increasing our fundamental understanding of the properties of materials making up the cells: CdTe, CdS, multilayer back-contact, and transparent conducting oxide (TCO) from contact. We emphasize the r… more

Transmutation of americium and curium using zirconia-based host materials

Description: We have investigated the incorporation of americium and curium in selected zirconia-based materials in conjunction with a research program at the ''Commissariat a l'Energie Atomique'' that addresses transmutation of long-lived radioactive elements. Both cubic zirconia and pyrochlore oxides An{sub 2}Zr{sub 2}O{sub 7} (An = Am, Cm) are considered in the work reported here. The strategy proposed is to treat americium and curium together in the same transmutation process. There are several incentiv… more

Is there elliptic flow without transverse flow?

Description: Azimuthal anisotropy of final particle distributions was originally introduced as a signature of transverse collective flow. We show that finite anisotropy in momentum space can result solely from the shape of the particle emitting source. However, by comparing the differential anisotropy to recent data from STAR collaboration we can exclude such a scenario, but instead show that the data favour strong flow as resulting from a hydrodynamical evolution.

Intelligent Software Tools for Advanced Computing

Description: Feature extraction and evaluation are two procedures common to the development of any pattern recognition application. These features are the primary pieces of information which are used to train the pattern recognition tool, whether that tool is a neural network, a fuzzy logic rulebase, or a genetic algorithm. Careful selection of the features to be used by the pattern recognition tool can significantly streamline the overall development and training of the solution for the pattern recognition… more
