Office of Compliance: Status of Management Control Efforts to Improve Effectiveness

Description: A letter report issued by the General Accounting Office with an abstract that begins "The Consolidated Appropriations Resolution of 2003 Conference Report mandated that GAO review the Office of Compliance (OOC), an independent legislative branch agency created by the Congressional Accountability Act of 1995 (CAA). OOC, a 15-person office with about $2 million in expenditures during fiscal year 2003, administers and enforces various CAA provisions related to fair employment and occupational safe… more

Congressional Continuity of Operations (COOP): An Overview of Concepts and Challenges

Description: Interruptions of congressional operations by incidents such as episodic computer virus infections and the 2001 anthrax contamination, the February 2004 ricin incident have demonstrated the importance of congressional continuity of operations (COOP) planning. This report discusses the circumstances surrounding COOP planning, including provisions for alternative meeting sites and methods for conducting House and Senate meetings and floor sessions when Capitol facilities are not available.

Implicit Occluders

Description: In this paper we propose a novel visibility-culling technique for optimizing the computation and rendering of opaque isosurfaces. Given a continuous scalar field f (x) over a domain D and an isovalue w, our technique exploits the continuity of f to determine conservative visibility bounds implicitly, i.e., without the need for actually computing the isosurface f{sup -1}(w). We generate Implicit Occluders based on the change in sign of f *(x) = f (x)-w, from positive to negative (or vice versa) … more

Arsenic Mobilization from Contaminated Sediments: A Full-scale Experiment in Progress

Description: The mobilization of arsenic was examined in a system where the deposition of iron and arsenic have been substantially modified by large-scale manipulations. This engineering practice was designed to decrease arsenic concentrations in water supplied to the City of Los Angeles. Accomplishing this objective, however, has resulted in significant accumulation of arsenic and iron in the sediments of a reservoir on the Los Angeles Aqueduct. Arsenic and iron are released into the porewater at depth in … more

Properties of Fluid Deuterium under Double-Shock Compression to Several Mbar

Description: The compressibility of fluid deuterium up to several Mbar has been probed using laser-driven shock waves reflected from a quartz anvil. Combining high-precision ({approx} 1 %) shock velocity measurements with the double-shock technique, where differences in equation of state (EOS) models are magnified, has allowed us to accurately discriminate between various theoretical predictions. Our data are consistent with EOS models that show approximately fourfold compression on the principal Hugoniot f… more

REC Tracking Systems Design Guide

Description: OAK-B135 The Design Guide is presented in three parts. Section II describes the need for REC tracking, the two principal tracking methods available, and, in simple terms, the operation of certificate-based systems. Section III presents the major issues in the design of certificate-based tracking systems and discusses the advantages and disadvantages of alternative solutions. Finally, Section IV offers design principles or recommendations for most of these issues.

Combating Terrorism: Evaluation of Selected Characteristics in National Strategies Related to Terrorism

Description: Testimony issued by the General Accounting Office with an abstract that begins "Following the terrorist attacks of September 11, 2001, the Bush administration developed and published seven national strategies that relate, in part or in whole, to combating terrorism and homeland security. These were National Security Strategy of the United States of America; National Strategy for Homeland Security; National Strategy for Combating Terrorism; National Strategy to Combat Weapons of Mass Destruction… more

Monte Carlo Models for the Production of beta-delayed Gamma Rays Following Fission of Special Nuclear Materials

Description: A Monte Carlo method for the estimation of {beta}-delayed {gamma}-ray spectra following fission is described that can accommodate an arbitrary time-dependent fission rate and photon collection history. The method invokes direct sampling of the independent fission yield distributions of the fissioning system, the branching ratios for decay of individual fission products and the spectral distributions for photon emission for each decay mode. Though computationally intensive, the method can provid… more

Leaching of Cadmium, Tellurium and Copper From Cadmium Telluride Photovoltaic Modules.

Description: Separating the metals from the glass is the first step in recycling end-of-life cadmium telluride photovoltaic modules and manufacturing scrap. We accomplished this by leaching the metals in solutions of various concentrations of acids and hydrogen peroxide. A relatively dilute solution of sulfuric acid and hydrogen peroxide was found to be most effective for leaching cadmium and tellurium from broken pieces of CdTe PV modules. A solution comprising 5 mL of hydrogen peroxide per kg of PV scrap … more

An Application of the Coda Methodology for Moment-Rate Spectra Using Broadband Stations in Turkey

Description: A recently developed coda magnitude methodology was applied to selected broadband stations in Turkey for the purpose of testing the coda method in a large, laterally complex region. As found in other, albeit smaller regions, coda envelope amplitude measurements are significantly less variable than distance-corrected direct wave measurements (i.e., L{sub g} and surface waves) by roughly a factor 3-to-4. Despite strong lateral crustal heterogeneity in Turkey, we found that the region could be ade… more

Water Sorption and Radiolysis Studies for Neptunium Oxides

Description: Plans are to convert the {sup 237}Np that is currently stored as a nitrate solution at the Savannah River Site to NpO{sub 2} and then ship it to the Y-12 National Security Complex in Oak Ridge for interim storage. This material will serve as feedstock for the {sup 238}Pu production program, and some will be periodically shipped to the Oak Ridge National Laboratory (ORNL) for fabrication into targets. The safe storage of this material requires an understanding of the radiolysis of moisture that … more

CODA-DERIVED SOURCE SPECTRA, MOMENT MAGNITUDES, AND ENERGY-MOMENT SCALING IN THE WESTERN ALPS

Description: A stable estimate of the earthquake source spectra in the western Alps is obtained using an empirical method based on coda envelope amplitude measurements described by Mayeda et al. (2003) for events ranging between M{sub W} {approx} 1.0 to {approx}5.0. We calibrated path corrections for consecutive narrow frequency bands ranging between 0.2 and 25.0-Hz using a simple 1-D model for 5 three-component stations of the Regional Seismic network of Northwestern Italy (RSNI). The 1-D assumption perfor… more
