TANK 241-AN-107 CORROSION COUPON LABORATORY ANALYSIS

Description: To support the corrosion study for Tank 241-AN-107, corrosion coupons consisting of C-rings and pins were removed from four detectors of the corrosion probe retrieved from the tank. The detectors were located as follows: one in the sludge layer, one in the liquid layer, one in the lower head space and the last in the upper head space. ASTM Method G-190 was used to determine the amount of corrosion product present.

High-Resolution Adaptive Optics Test-Bed for Vision Science

Description: We discuss the design and implementation of a low-cost, high-resolution adaptive optics test-bed for vision research. It is well known that high-order aberrations in the human eye reduce optical resolution and limit visual acuity. However, the effects of aberration-free eyesight on vision are only now beginning to be studied using adaptive optics to sense and correct the aberrations in the eye. We are developing a high-resolution adaptive optics system for this purpose using a Hamamatsu Paralle… more

A complete analytic inversion of supernova lines in the Sobolevapproximation

Description: We show that the shape of P-Cygni line profiles of photospheric phase supernova can be analytically inverted to extract both the optical depth and source function of the line -- i.e. all the physical content of the model for the case when the Sobolev approximation is valid. Under various simplifying assumptions, we derive formulae that give S(r) and {tau}(r) in terms of derivatives of the line flux with respect to wavelength. The transition region between the minimum and maximum of the line pro… more

Geochemistry Model Validation Report: External Accumulation Model

Description: The purpose of this Analysis and Modeling Report (AMR) is to validate the External Accumulation Model that predicts accumulation of fissile materials in fractures and lithophysae in the rock beneath a degrading waste package (WP) in the potential monitored geologic repository at Yucca Mountain. (Lithophysae are voids in the rock having concentric shells of finely crystalline alkali feldspar, quartz, and other materials that were formed due to entrapped gas that later escaped, DOE 1998, p. A-25.… more

The ORNL Modulating Heat Pump Design Tool -- Mark IV User's Guide

Description: The ORNL Modulating Heat Pump Design Tool consists of a Modulating HPDM (Heat Pump Design Model) and a parametric-analysis (contour-data generating) front-end. Collectively the program is also referred to as MODCON which is in reference to the modulating and the contour data generating capabilities. The program was developed by Oak Ridge National Laboratory for the Department of Energy to provide a publicly-available system design tool for variable- and single-speed heat pumps.

Uranium Enrichment Measurements without Calibration Using Gamma Rays Above 100 keV

Description: The verification of UF{sub 6} shipping cylinders is an important activity in routine safeguards inspections. Current measurement methods using either sodium-iodide or high-purity germanium detectors require calibrations that are not always appropriate for field measurements, because of changes in geometry or container wall thickness. The introduction of the MGAU code demonstrated the usefulness of intrinsically calibrated measurements for inspections. MGAU uses the 100-keV region of the uranium… more

Plan for PLEX X-Ray Ablation Experiments and Analysis

Description: PLEX is a Z-pinch based x-ray source that can produce x-rays with fluences (0.3-18 J/cm{sup 2}), pulselengths (10-30 ns), repetition rates (<10 Hz), and energies (50-500 eV) of interest for IFE chambers and optics. It provides an affordable, dedicated method to advance our understanding of x-ray damage to materials. The PLEX x-ray source will be used to experimentally validate and further develop the ABLATOR x-ray ablation code for use in inertial fusion energy (IFE) studies.

The Framework for Approximate Queries on Simulation Data

Description: AQSim is a system intended to enable scientists to query and analyze a large volume of scientific simulation data. The system uses the state of the art in approximate query processing techniques to build a novel framework for progressive data analysis. These techniques are used to define a multi-resolution index, where each node contains multiple models of the data. The benefits of these models are two-fold: (1) they are compact representations, reconstructing only the information relevant to t… more

Finding Clusters of Galaxies in the Sloan Digital Sky Survey using Voronoi Tessellation

Description: The Sloan Digital Sky Survey has obtained 450 square degrees of photometric scan data, in five bands (u', g', r', i', z'), which the authors use to identify clusters of galaxies. They illustrate how they do star-galaxy separation, and present a simple and elegant method of detecting over-densities in the galaxy distribution, using the Voronoi Tessellation.

ELECTRONIC AND CHEMICAL PROPERTIES OF PD IN BIMETALLIC SYSTEMS: HOW MUCH DO WE KNOW ABOUT HETERONUCLEAR METAL-METAL BONDING?

Description: The experimental and theoretical studies described above illustrate the complex nature of the heteronuclear metal-metal bond. In many cases, bimetallic bonding induces a significant redistribution of charge around the bonded metals. This redistribution of charge is usually linked to the strength of the bimetallic bond, affects the position of the core and valence levels of the metals, and can determine the chemical reactivity of the system under study. New concepts are emerging [22,23,34,36] an… more

QCD at the Tevatron: Jets and fragmentation

Description: At the Fermilab Tevatron energies, ({radical} s=1800 GeV and {radical} s = 630 GeV), jet production is the dominant process. During the period 1992-1996, the D0 and CDF experiments accumulated almost 100 pb{sup -1} of data and performed the most accurate jet production measurements up to this date. These measurements and the NLO-QCD theoretical predictions calculated during the last decade, have improved our understanding of QCD, our knowledge of the proton structure, and pushed the limit to th… more

Martial Law and National Emergency

Description: Crises in public order, both real and potential, often evoke comments concerning a resort to martial law. While some ambiguity exists regarding the conditions of a martial law setting, such a prospect, nonetheless, is disturbing to many Americans who cherish their liberties, expect civilian law enforcement to prevail, and support civilian control of the military authority. An overview of the concept of, the exercise of, and authority underlying martial law is provided in this report, which will… more
