China, Congress, and Sanctions - Findings of a Workshop-Seminar

Description: The People's Republic of China (PRC)'s provocative use of military force in the Taiwan Strait has appeared to subside, but not before convincing many in the Congress that the PRC regime continues to flout international norms sensitive to the United States. In addition to challenging stability in the Taiwan Strait, the PRC is seen recently to undermine important U.S. interests regarding nuclear proliferation, intellectual property rights, and missile proliferation. As a result, many in the Congr… more

Effects of Flat Taxes and Other Proposals on Housing: An Overview

Description: Studies have estimated that some of these revisions would cause a decline in demand for houses and significant reduction in house prices--perhaps in excess of 15 percent. These studies, however, presumed a fixed supply of housing; even a limited supply response would greatly decrease predicted asset price effects. Supply response is likely to be large in the long run and not insignificant in the short run. Effects on housing demand might also be mitigated by increases in savings rates and lower… more

Laser aperture diagnostics system for gain and wavefront measurements on NIF/LMJ amplifiers

Description: We are in the midst of constructing an amplifier laboratory (Arnplab) that will be the physics and engineering proving ground for fill sized segmented glass amplifiers of designs that will outfit the National Ignition Facility (NIF) and Laser Megajoule (LMJ) projects. Amplab will demonstrate the cornerstone mechanical, electrical and optical concepts that support the NW and LMJ amplifier schemes. Here we address the optical diagnostics that will be used to characterize optical performance of th… more

Compact IR laser for calibration of space based sensors

Description: An Er:YAG laser, operating at 2.94 microns, has been developed for in-theater calibration of space based infrared sensors. The laser is used to illuminate a spaceborne sensor focal plane from a surveyed ground reference point. The known reference point is compared to the laser position reported by the sensor, and boresight corrections are made. The Er:YAG laser is side pumped by a InGaAs diode array and is tuned to an atmospheric microwindow with and intracavity etalon. This technology is being… more

X-ray spectra from convective photospheres of neutron stars

Description: We present first results of modeling convective photospheres of neutron stars. We show that in photospheres composed of the light elements convection arises only at relatively low effective temperatures ({le}3 - 5 x 10{sup 4} K), whereas in the case of iron composition it arises at T{sub eff}{le} 3 x 10{sup 5}K. Convection changes the depth dependence of the photosphere temperature and the shapes of the emergent spectra. Thus, it should be taken into account for the proper interpretation of EUV… more

Discrete optimization of isolator locations for vibration isolation systems: An analytical and experimental investigation

Description: An analytical and experimental study is conducted to investigate the effect of isolator locations on the effectiveness of vibration isolation systems. The study uses isolators with fixed properties and evaluates potential improvements to the isolation system that can be achieved by optimizing isolator locations. Because the available locations for the isolators are discrete in this application, a Genetic Algorithm (GA) is used as the optimization method. The system is modeled in MATLAB{trademar… more

Full Body Powder Antichip. Final Report

Description: Chipping is the major paint defect listed for automobile customer dissatisfaction. The improved chip resistance and smoother paint surfaces produced by full body powder antichip will result in greater customer satisfaction and greater demand for US-produced automobiles. Powder antichip contains virtually no solvent, thereby reducing the potential VOC emissions from Newark Assembly by more than 90 tons per year as compared to the solvent-borne material presently applied in most full body applica… more

Application of MXCD to magnetic thin-film sensors

Description: While Magnetic X-ray Circular Dichroism (MXCD) has been applied extensively to the extraction of elemental magnetic moments in various magnetic multilayers, the configuration of actual devices imposes certain constraints on the application of MXCD to devices. Using a set of real, thin-film spin valve devices with varying Cu spacer layer thicknesses, we demonstrate the correlation between MXCD and R-H measurements on those devices as well as the restrictions on the interpretation of MXCD data im… more

Optical and thermo-optical characterization of KTP and its isomorphs for 1.06 {micro}m pumped OPO`s

Description: The need to protect personnel from inadvertent eye trauma from fielded laser sources dictates that the highest externally accessible fluences produced by these systems be kept below the maximum permissible exposure (MPE) for intra-beam viewing. The large MPE value for a typical Q-switched (10 ns pulsewidth) source is 1 J/cm{sup 2} for wavelengths in the range of 1.5--1.8 microns, while the MPE for a similar pulsewidth Nd:YAG source is 5 {micro}J/cm{sup 2}. This 5 order of magnitude difference i… more

Hypertools in image and volume visualization

Description: This paper describes our experience in image and volume visualization at the Lawrence Livermore National Laboratory. After an introduction on visualization issues, we present a new software approach to the analysis and visualization of images and volumes. The efficiency of the visualization process is improved by letting the user combine small and reusable applications by the means of a machine-independent interpreted language such as Tcl/Tk. These hypertools can communicate with each other ove… more

Self-consistent core-edge nonlinear transport simulations with CORSICA 2

Description: The coupled core-edge nonlinear transport code CORSICA 2 is introduced and the structure of its iterative coupling algorithm is briefly discussed. Selected application results are reported that reproduce equilibria in DIII-D discharges with plasma profiles initialized from the experimental data. Simulations for an L-H transition and for a gas puffing experiment in DIII-D plasmas are presented.

An integrated study of the Grayburg/San Andres reservoir, Foster and south Cowden fields, Ector County, Texas. Quarterly report, January 1--March 31, 1996

Description: The principal objective of this research is to demonstrate in the field that 3D seismic data can be used to aid in identifying porosity zones, permeability barriers and thief zones and thereby improve waterflood design. Geologic and engineering data will be integrated with the geophysical data to result in a detailed reservoir characterization. Reservoir simulation will then be used to determine infill drilling potential and the optimum waterflood design for the project area. This design will b… more
