Underinflated Tires in the United States

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "More than a quarter of automobiles and about a third of light trucks (including sport utility vehicles, vans, and pickup trucks) on the roadways of the United States have one or more tires underinflated 8 pounds per square inch (psi) or more below the level recommended by the vehicle manufacturer, according to a report by the Department of Transportation's (DOT) National Highway Traffic Safety Administra… more

Prescription Drugs: Oversight of Drug Pricing in Federal Programs

Description: Testimony issued by the Government Accountability Office with an abstract that begins "Several federal programs help pay for or reduce the costs of prescription drugs for eligible individuals and entities. Three examples are the Medicaid drug rebate program, part of the joint federal-state Medicaid program that finances medical services for certain low-income people; the 340B drug pricing program, which provides discounted drug prices to certain eligible entities such as community health center… more

Dairy Policy Issues

Description: Two federal programs that support the price and income received by dairy farmers are expiring in 2007 — the dairy price support program and the Milk Income Loss Contract (MILC) program. This report discusses the reauthorization of these and other farm commodity price and income support programs, which is being debated by the 110th Congress in the context of a pending omnibus 2007 farm bill.

Final Report

Description: The purpose of this project was to investigate metal-induced crystallization of amorphous silicon at low temperatures using excitation sources such as laser and rapid thermal annealing, as well as, electric field. Deposition of high quality crystalline silicon at low temperatures allows the use of low cost soda-lime glass and polymeric films for economically viable photovoltaic solar cells and low cost large area flat panel displays. In light of current and expected demands on Si supply due to … more

Gas Detector LCLS Engineering Specifications Document

Description: There are two Gas Detectors, located upstream and downstream of the FEL attenuation materials, which provide a non-intrusive measure of the FEL pulse energy in the fundamental, in real-time, on a pulse-by-pulse basis. The FEL operators and the users will use this information to monitor the performance of the FEL and the Attenuator and to cross-calibrate other detectors. The Gas Detectors measure the FEL pulse energy by measuring the fluorescence induced in a small volume of N{sub 2} gas by the … more

SAMPLING AND ANALYSIS PROTOCOLS

Description: Radiological sampling and analyses are performed to collect data for a variety of specific reasons covering a wide range of projects. These activities include: Effluent monitoring; Environmental surveillance; Emergency response; Routine ambient monitoring; Background assessments; Nuclear license termination; Remediation; Deactivation and decommissioning (D&D); and Waste management. In this chapter, effluent monitoring and environmental surveillance programs at nuclear operating facilities a… more

The Effect of Diluent Gases In The Shock Tube and Rapid Compression Machine

Description: Studying the details of hydrocarbon chemistry in an internal combustion engine is not straightforward. A number of factors, including varying conditions of temperature and pressure, complex fluid motions, as well as variation in the composition of gasoline, render a meaningful characterization of the combusting system difficult. Some simplified experimental laboratory devices offer an alternative to complex engine environments: they remove some of the complexities that exist in real engines but… more

Charm and Charmonium Spectroscopy From B-Factories

Description: New and recent results are presented on charm and charmonium spectroscopy from BABAR experiment at SLAC. In particular, measurements on D{sub sJ} states branching fractions have been performed both in B-decays and inclusive e{sup +}e{sup -} {yields} c{bar c} interactions. Here a search for D{sub sj}(2632) has been performed and a new D{sub sJ} state at a mass of 2.856 GeV/c{sup 2} has been observed. A search for Y(4260) has been performed in exclusive D{sub D} production from initial-state radi… more

Integrated Seismic Event Detection and Location by Advanced Array Processing

Description: The principal objective of this two-year study is to develop and test a new advanced, automatic approach to seismic detection/location using array processing. We address a strategy to obtain significantly improved precision in the location of low-magnitude events compared with current fully-automatic approaches, combined with a low false alarm rate. We have developed and evaluated a prototype automatic system which uses as a basis regional array processing with fixed, carefully calibrated, site… more

An Accelerated Collaboration Meets with Beaming Success

Description: Maintaining a smaller, aging U.S. nuclear weapons stockpile without underground nuclear testing requires the capability to verify and validate the complex computer calculations on which stockpile confidence is based. This capability, in turn, requires nonnuclear hydrodynamic tests (hydrotests) that can x-ray stages of the implosion process, providing freeze-frame photos of materials imploding at speeds of more than 16,000 kilometers per hour. The images will yield important information on shape… more

CALCULATION OF TRITIUM RETENTION AND RELEASE FROM COMPONENTS IN GROUT- SEGMENT 6 METALLIC WASTE FROM DEMOLISHED BUILDING 232-F

Description: The amount of tritium remaining within and the release rate out of stainless steel process waste from the 232-F Tritium Facility at SRS is calculated as a function of time using the historical exposure of pipe during operation of the facility (1955-1958) and its subsequent deactivation and lay-up. The solution and diffusion of tritium in the wall is the mechanism that governs both the tritium contamination of the pipe during operation and its gradual release after deactivation, including radioa… more

Reliability Analysis of Brittle, Thin Walled Structures

Description: One emerging application for ceramics is diesel particulate filters being used order to meet EPA regulations going into effect in 2008. Diesel particulates are known to be carcinogenic and thus need to be minimized. Current systems use filters made from ceramics such as mullite and corderite. The filters are brittle and must operate at very high temperatures during a burn out cycle used to remove the soot buildup. Thus the filters are subjected to thermal shock stresses and life time reliabilit… more

Signal-to-Noise Behavior for Matches to Gradient Direction Models of Corners in Images

Description: Gradient direction models for corners of prescribed acuteness, leg length, and leg thickness are constructed by generating fields of unit vectors emanating from leg pixels that point normal to the edges. A novel FFT-based algorithm that quickly matches models of corners at all possible positions and orientations in the image to fields of gradient directions for image pixels is described. The signal strength of a corner is discussed in terms of the number of pixels along the edges of a corner in… more
