Military Personnel: Navy Actions Needed to Optimize Ship Crew Size and Reduce Total Ownership Costs (open access)

Military Personnel: Navy Actions Needed to Optimize Ship Crew Size and Reduce Total Ownership Costs

A letter report issued by the General Accounting Office with an abstract that begins "The cost of a ship's crew is the single largest incurred over the ship's life cycle. One way to lower personnel costs, and thus the cost of ownership, is to use people only when it is cost-effective--a determination made with a systems engineering approach called human systems integration. GAO was asked to evaluate the Navy's progress in optimizing the crew size in four ships being developed and acquired: the DD(X) destroyer, T-AKE cargo ship, JCC(X) command ship, and LHA(R) amphibious assault ship. GAO assessed (1) the Navy's use of human systems integration principles and goals for reducing crew size, and (2) the factors that may impede the Navy's use of those principles."

Mutual Funds: Greater Transparency Needed in Disclosures to Investors

A letter report issued by the General Accounting Office with an abstract that begins "The fees and other costs that investors pay as part of owning mutual fund shares can significantly affect their investment returns. As a result, questions have been raised as to whether the disclosures of mutual fund fees and other practices are sufficiently transparent. GAO reviewed (1) how mutual funds disclose their fees and related trading costs and options for improving these disclosures, (2) changes in how mutual funds pay for the sale of fund shares and how the changes in these practices are affecting investors, and (3) the benefits of and the concerns over mutual funds' use of soft dollars."

Information Technology: Homeland Security Needs to Improve Entry Exit System Expenditure Planning (open access)

Information Technology: Homeland Security Needs to Improve Entry Exit System Expenditure Planning

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to legislative direction, the Immigration and Naturalization Service (INS), now part of the Department of Homeland Security, plans to acquire and deploy an entry exit system to assist in monitoring the flow of foreign nationals in and out of the United States. By separate legislative direction, INS must submit to the Senate and House Committees on Appropriations a plan for this system that meets certain conditions, including being reviewed by GAO, before funds can be obligated. This report satisfies GAO's mandated review obligation by (1) addressing whether the plan submitted by INS, along with related INS documentation and plans, meets required conditions and (2) providing observations about the plan and INS's management of the system."

Best Practices: Improved Knowledge of DOD Service Contracts Could Reveal Significant Savings (open access)

Best Practices: Improved Knowledge of DOD Service Contracts Could Reveal Significant Savings

A letter report issued by the General Accounting Office with an abstract that begins "Department of Defense (DOD) spending on service contracts approaches $100 billion annually, but DOD's management of services procurement is inefficient and ineffective and the dollars are not always well spent. Recent legislation requires DOD to improve procurement practices to achieve savings. Many private companies changed management practices based on analyzing spending patterns and coordinating procurement in order to achieve major savings. This report evaluates five companies' best practices and their conduct and use of "spend analysis" and the extent that DOD can pursue similar practices."

Flexibility Demonstration Programs: Education Needs to Better Target Program Information (open access)

Flexibility Demonstration Programs: Education Needs to Better Target Program Information

A letter report issued by the General Accounting Office with an abstract that begins "The No Child Left Behind Act of 2001 (NCLBA) has focused national attention on increasing accountability for states and school districts to improve student achievement. While increasing accountability, NCLBA also provided states and school districts with additional flexibility. The act established two flexibility demonstration programs--State- and Local-Flex--which allow up to 7 states and 80 school districts to redirect up to 100 percent of certain NCLBA program funds. GAO was asked to determine factors that affect states' and districts' decisions whether or not to apply for the demonstration programs and to determine the extent to which the U.S. Department of Education publicized, provided guidance, and established a process to review and award flexibility demonstration programs. To address these questions, GAO conducted a study, using telephone interviews with officials in 22 states and 37 school districts, and site visits to 2 of the four applicants."

HotEye (tm) Based Coordinate Measuring Machine for Forging Industry (open access)

HotEye (tm) Based Coordinate Measuring Machine for Forging Industry

The objective of this project is to develop a 3 dimensional measurement system for the domestic forging industry based on HotEye{trademark}. This technology will allow high definition camera to accurately image a red hot object. The project marries conventional Coordinate Measurement Machine ''CMM'' technology to HotEye{trademark} technology to permit the accurate measurement of forged parts while they are at high temperature. Being able to take such measurements will dramatically reduce the amount of scrap produced by the domestic forging industry. This industry wastes a significant amount of energy because of the high rate of scrap it produces. OGT will: (1) Develop a 3D measurement sensor head that will work on a part at a temperature up to 1,450 C with an accuracy of 0.1mm or better and with a scanning speed of less than 10 seconds for an area of 100mm x 100mm. (2) Develop a Virtual-Fixturing software package to alleviate the need of precise hard fixturing. (3) Integrate the 3D measurement sensor head and the Virtual-Fixturing software into a standard CMM, both hardware (replacing the probes) and software (data format and user interface match) so that the system can automatically perform a complete preprogrammed measurement of a hot product. …

Self-Organized Superlattices in GaInAsSb Grown on Vicinal Substrates (open access)

Self-Organized Superlattices in GaInAsSb Grown on Vicinal Substrates

Self-organized superlattices are observed in GaInAsSb epilayers grown lattice matched to vicinal GaSb substrates. The natural superlattice (NSL) is oriented at a slight angle of about 4{sup o} with respect to the vicinal (001) GaSb substrate. This vertical composition modulation is detected at the onset of growth. Layers in the NSL are continuous over the lateral extent of the substrate. Furthermore, the NSL persists throughout several microns of deposition. The NSLs have a period ranging from 10 to 30 nm, which is dependent on deposition temperature and GaInAsSb alloy composition. While the principle driving force for this type of phase separation is chemical, the mechanism for the self-organized microstructure is related to local strains associated with surface undulations. By using a substrate with surface undulations, the tilted NSL can be induced in layers with alloy compositions that normally do not exhibit this self-organized microstructure under typical growth conditions. These results underscore the complex interactions between compositional and morphological perturbations.

Probabilistic and numerical techniques in the study of statistical theories of turbulence. Final Technical Report (open access)

Probabilistic and numerical techniques in the study of statistical theories of turbulence. Final Technical Report

In this research project we made fundamental advances in a number of problems arising in statistical equilibrium theories of turbulence. Here are the highlights. In most cases the mathematical analysis was supplemented by numerical calculations. (a) Maximum entropy principles. We analyzed in a unified framework the Miller-Robert continuum model of equilibrium states in an ideal fluid and a modification of that model due to Turkington. (b) Equivalence and nonequivalence of ensembles. We gave a complete analysis of the equivalence and nonequivalence of the microcanonical, canonical, and mixed ensembles at the level of equilibrium macrostates for a large class of models of turbulence. (c) Nonlinear stability of flows. We refined the well known Arnold stability theorems by proving the nonlinear stability of steady mean flows for the quasi-geostrophic potential vorticity equation in the case when the ensembles are nonequivalent. (d) Geophysical application. The theories developed in items (a), (b), and (c) were applied to predict the emergence and persistence of coherent structures in the active weather layer of the Jovian atmosphere. This is the first work in which sophisticated statistical theories are synthesized with actual observations data from the Voyager and Galileo space missions. (e) Nonlinear dispersive waves.

Science Based Stockpile Stewardship and RIA (open access)

Science Based Stockpile Stewardship and RIA

One aspect of Science Based Stockpile Stewardship (SBSS) is to improve the quality of neutron cross section data for certain isotopes. The isotopes of interest are used to monitor neutron and charged particle fluxes in environments of brief, intense neutron fluxes. The accuracy of flux determination is dependent on the accuracy of cross section data for the stable isotopes loaded into the system and the unstable isotopes produced when the neutrons are incident on the monitor. For isotopes with a half-life greater than one day it is possible, given the production rates of RIA, to make radioactive targets for neutron irradiation. This would require the ability to harvest isotopes at RIA, an onsite radiochemistry facility for processing the harvested material into a target, and an onsite neutron source facility. The radiochemistry facility will need to handle activity levels on the order of 100's of Curie's while the neutron source facility will need to provide high intensity ''monoenergetic'' neutrons from 10's keV to 20 MeV. For isotopes with a half-life much less than one day, only indirect methods can be used to get information on the neutron cross sections because of the lack of a target. Both experimental techniques will be …

Radioanalytical Chemistry for Automated Nuclear Waste Process Monitoring (open access)

Radioanalytical Chemistry for Automated Nuclear Waste Process Monitoring

This research program is directed toward rapid, sensitive, and selective determination of beta and alpha-emitting radionuclides such as 99Tc, 90Sr, and trans-uranium (TRU) elements in low activity waste (LAW) processing streams. The overall technical approach is based on automated radiochemical measurement principles. Nuclear waste process streams are particularly challenging for rapid analytical methods due to the complex, high- ionic-strength, caustic brine sample matrix, the presence of interfering radionuclides, and the variable and uncertain speciation of the radionuclides of interest. As a result, matrix modification, speciation control, and separation chemistries are required for use in automated process analyzers. Significant knowledge gaps exist relative to the design of chemistries for such analyzers so that radionuclides can be quantitatively and rapidly separated and analyzed in solutions derived from low-activity waste processing operations. This research is addressing these knowledge gaps in the area of separation science, nuclear detection, and analytical chemistry and instrumentation. The outcome of these investigations will be the knowledge necessary to choose appropriate chemistries for sample matrix modification and analyte speciation control and chemistries for rapid and selective separation and preconcentration of target radionuclides from complex sample matrices. In addition, new approaches for quantification of alpha emitters in solution using solid …

Using 3D Computer Modeling, Borehole Geophysics, and High Capacity Pumps to Restore Production to Marginal Wells in the East Texas Field (open access)

Using 3D Computer Modeling, Borehole Geophysics, and High Capacity Pumps to Restore Production to Marginal Wells in the East Texas Field

Methods for extending the productive life of marginal wells in the East Texas Field were investigated using advanced computer imaging technology, geophysical tools, and selective perforation of existing wells. Funding was provided by the Department of Energy, TENECO Energy and Schlumberger Wireline and Testing. Drillers' logs for more than 100 wells in proximity to the project lease were acquired, converted to digital format using a numerical scheme, and the data were used to create a 3 Dimensional geological image of the project site. Using the descriptive drillers' logs in numerical format yielded useful cross sections identifying the Woodbine Austin Chalk contact and continuity of sand zones between wells. The geological data provided information about reservoir continuity, but not the amount of remaining oil, this was obtained using selective modern logs. Schlumberger logged the wells through 2 3/8 inch tubing with a new slimhole Reservoir Saturation Tool (RST) which can measure the oil and water content of the existing porosity, using neutron scattering and a gamma ray spectrometer (GST). The tool provided direct measurements of elemental content yielding interpretations of porosity, lithology, and oil and water content, confirming that significant oil saturation still exists, up to 50% in the upper Woodbine …
