Social Security Numbers: Private Sector Entities Routinely Obtain and Use SSNs, and Laws Limit the Disclosure of This Information

Description: A letter report issued by the General Accounting Office with an abstract that begins "In 1936, the Social Security Administration (SSA) established the Social Security number (SSN) to track workers' earnings for Social Security benefit purposes. However, the SSN is also used for a myriad of non-Social Security purposes. Today, public and private sector entities view the SSN as a key piece of information that enables them to conduct their business and deliver services. However, given the apparen… more

Concurrent Multiscale Simulation at Finite Temperature: Coarse-Grained Molecular Dynamics

Description: With the advent of nanotechnology, predictive simulations of nanoscale systems have become in great demand. In some cases nanoscale systems can be simulated directly at the level of atoms. The atomistic techniques used range from models based on a quantum mechanical treatment of the electronic bonds to those based on more empirical descriptions of the interatomic forces. In many cases, however, even nanoscale systems are too big for a purely atomistic approach, typically because the nanoscale d… more

After-hours Power Status of Office Equipment and Inventory of Miscellaneous Plug-load Equipment

Description: This research was conducted in support of two branches of the EPA ENERGY STAR program, whose overall goal is to reduce, through voluntary market-based means, the amount of carbon dioxide emitted in the U.S. The primary objective was to collect data for the ENERGY STAR Office Equipment program on the after-hours power state of computers, monitors, printers, copiers, scanners, fax machines, and multi-function devices. We also collected data for the ENERGY STAR Commercial Buildings branch on the t… more

Utilizing Strong Tight Intermodal Waste Packaging to Meet Accelerated Cleanup Goals at The Savannah River Site

Description: In support of the accelerated cleanup challenge, personnel at the Savannah River Site have been working diligently to identify and acquire cost-effective waste containers that can be used to package a voluminous amount of low level radioactive waste that needs to be disposed. In so doing, personnel have transformed their paradigm in packaging low level radioactive waste in traditional 45-cubic-foot and 90-cubic-foot containers and utilizing refurbished intermodal containers instead. The transit… more

A Hydrologic-geophysical Method for Characterizing Flow and Transport Processes Within The Vadose Zone

Description: The primary purpose of this project was to employ two geophysical imaging techniques, electrical resistivity tomography and cross-borehole ground penetrating radar, to image a controlled infiltration of a saline tracer under unsaturated flow conditions. The geophysical techniques have been correlated to other more traditional hydrologic measurements including neutron moisture measurements and induction conductivity logs. Images that resulted during two successive infiltrations indicate the deve… more

A Novel Membrane Reactor for Direct Hydrogen Production From Coal Quarterly Report

Description: Gas Technology Institute is developing a novel concept of membrane gasifier for high efficiency, clean and low cost production of hydrogen from coal. The concept incorporates a hydrogen-selective membrane within a gasification reactor for direct extraction of hydrogen from coal synthesis gases. The objective of this project is to determine the technical and economic feasibility of this concept by screening, testing and identifying the potential candidate membranes under high temperature, high p… more

Error Estimation for Reduced Order Models of Dynamical Systems

Description: The use of reduced order models to describe a dynamical system is pervasive in science and engineering. Often these models are used without an estimate of their error or range of validity. In this paper we consider dynamical systems and reduced models built using proper orthogonal decomposition. We show how to compute estimates and bounds for these errors, by a combination of small sample statistical condition estimation and error estimation using the adjoint method. Most importantly, the propo… more

Simultaneous Analyses and Applications of Multiple Fluorobenzoate and Halide Tracers in Hydrologic Studies

Description: An analytical method that employs ion chromatography has been developed to more fully exploit the use of fluorobenzoic acids (FBAs) and halides as hydrologic tracers. In a single run, this reliable, sensitive, and robust method can simultaneously separate and quantify halides (fluoride, chloride, bromide, and iodide) and up to seven FBAs from other common groundwater constituents (e.g., nitrate and sulfate). The usefulness of this ion chromatographic (IC) analytical method is demonstrated in bo… more

Retrieval Using Texture Features in High Resolution Multi-spectral Satellite Imagery

Description: Texture features have long been used in remote sensing applications to represent and retrieve image regions similar to a query region. Various representations of texture have been proposed based on the Fourier power spectrum, spatial co-occurrence, wavelets, Gabor filters, etc. These representations vary in their computational complexity and their suitability for representing different region types. Much of the work done thus far has focused on panchromatic imagery at low to moderate spatial re… more

Status of High Temperature Superconductor Magnet R and D at Bnl.

Description: We report the status and test results of the High Temperature Superconductor (HTS) cable and magnet R&D at Brookhaven National Laboratory (BNL). If successful, this will enhance the performance and reduce the cost of operation of magnets that must absorb a large amount of energy. The need for developing this technology has been seen in a number of high field magnet applications for high energy colliders, and a medium field application in the proposed Rare Isotope Accelerator (RIA). The like… more

Final report summary of LDRD 02-LW-022''Quantum Vibrations in Molecules: A New Frontier in Computational Chemistry''

Description: With the trend towards needing information about chemistry at conditions significantly different from 298K and 1 atm., methods need to be developed to generate and interpret this data. This demand for information about chemistry at extreme conditions comes from many fields. The study of atmospheric chemistry requires knowledge of unusual species that are formed when molecules are exposed to ultraviolet radiation. Studying of energetic materials requires knowledge of the thermochemical and struc… more

Dual-Use Biological Equipment: Difficulties in Domestic Regulation

Description: A question in the current debate over chemical and biological terrorism is: how well do current United States policies limit opportunities to terrorist groups for acquisition of such weapons? The domestic purchase and use of “dual-use” biological equipment, such as fermenters, centrifuges, and other equipment, is one area suggested as potentially providing opportunities for terrorist, biological weapons development. Dual-use equipment has both legitimate civilian and military use. Regulating in… more

Campaign Finance: Constitutional and Legal Issues of Soft Money

Description: Prior to enactment of the Bipartisan Campaign Reform Act of 2002 (BCRA), P.L. 107-155, the term “soft money” generally referred to unregulated funds, perceived as resulting from loopholes in the Federal Election Campaign Act (FECA), 2 U.S.C. §§ 431 et seq. Generally, the intent of BCRA, (effective Nov. 6, 2002), which amends FECA, is to restrict the raising and spending of soft money. This Issue Brief discusses constitutional and legal issues surrounding two major types of soft money that BCRA … more
