Formulation of the Linear Response Theory in Relativistic LAPW Method. Calculation of Forces in Alpha-Pu

Description: Linear-response (LR) theory in combination with the first-principles band structure codes allows to calculate phonons in an efficient way. In this report a formalism which enables us to apply LR theory within an all-electron framework utilizing the relativistic full-potential linearized augmented plane-wave (RFLAPW) method is presented. As first part, the equations for the calculations of the atomic forces are given and they are used for the calculation of forces in {alpha}-Pu. As a second step… more

Techniques in Broadband Interferometry

Description: This is a compilation of my patents issued from 1997 to 2002, generally describing interferometer techniques that modify the coherence properties of broad-bandwidth light and other waves, with applications to Doppler velocimetry, range finding, imaging and spectroscopy. Patents are tedious to read in their original form. In an effort to improve their readability I have embedded the Figures throughout the manuscript, put the Figure captions underneath the Figures, and added section headings. Oth… more

Techniques for Judging Intent Behind Network Based Cyber Attacks

Description: This project developed a prototype system that can rapidly differentiate between undirected cyber attacks, and those that have a more specific and concerning intent behind them. The system responds to important cyber attacks in a tactically significant way as the attack is proceeding. It is also creates a prioritized list for the human analysts allowing them to focus on the threats mostly likely to be of interest. In the recent years the volume of attacks over the internet has increased exponen… more

Benson Beach Demonstration Project: Composition and Abundance of Biota at Three Alternative Sump Sites

Description: The Portland District of the U.S. Army Corps of Engineers is investigating plans to provide sediment to nourish beaches north of the Mouth of the Columbia River (MCR). Under the currently designed proposal, sediment dredged from the MCR will be temporarily stored at one of three proposed areas south of the North Jetty before being redredged and moved by a cutterhead pipeline dredge over the jetty to nourish Benson Beach. Resulting potential impacts to resident Dungeness crab (Cancer magister) a… more

Preliminary Thoughts on Introducing Structs to SIDL/Babel: White Paper

Description: In the past 6 months, there has been increased interest in adding something analogous to C structs to the SIDL language and the Babel language interoperability tool [2, 6]. In particular, Rob Armstrong, of the Common Component Architecture [4], said the lack of structs ''is an oft-cited reason that people can't use Babel.'' Because the interest is high and lack of structs is a barrier to Babel adoption, we must carefully consider the current work around, the motivations for structs, the implica… more

Optimal Resource Allocation in Electrical Network Defense

Description: Infrastructure networks supplying electricity, natural gas, water, and other commodities are at risk of disruption due to well-engineered and coordinated terrorist attacks. Countermeasures such as hardening targets, acquisition of spare critical components, and surveillance can be undertaken to detect and deter these attacks. Allocation of available countermeasures resources to sites or activities in a manner that maximizes their effectiveness is a challenging problem. This allocation must take… more

Estimated (n,f) cross sections for 236,236m237,238-Np, 237,237m-Pu, and 240,241,242,242m,243,244,244m-Am isotopes

Description: Neutron-induced fission cross sections on targets of {sup 236,236m,237,238}Np, {sup 237,237m}Pu, and {sup 240,241,242,242m,243,244,244m}Am have been estimated for incident neutron energies of up to 6 MeV, using the ''surrogate'' technique and the ({sup 3}He,df) and ({sup 3}He,tf) reactions on stable targets to measure fission probabilities. In isotopes where low-lying isomeric states are known to exist, the (n,f) cross section on the corresponding isomeric targets has been estimated, using the … more

Enhanced Video Surveillance (EVS) with speckle imaging

Description: Enhanced Video Surveillance (EVS) with Speckle Imaging is a high-resolution imaging system that substantially improves resolution and contrast in images acquired over long distances. This technology will increase image resolution up to an order of magnitude or greater for video surveillance systems. The system's hardware components are all commercially available and consist of a telescope or large-aperture lens assembly, a high-performance digital camera, and a personal computer. The system's s… more

Analytic Expressions for the Angular Resolution of Compton Gamma-ray Detectors

Description: This paper describes the derivation of analytic expressions for the angular resolution of reconstructing gamma rays detected via Compton interactions. We consider two types of gamma-ray detectors: Compton-ring and electron-tracking devices. In Compton-ring devices, the direction of the scattered electron is not resolved, only the total energy (electron and scattered photon) and the scattered photon direction are measured. The measured quantities define a cone about the axis of the scattered pho… more

Physics and Advanced Technologies LDRD Final Report:Adaptive Optics Imaging and Spectroscopy of the Solar System

Description: This focus of this project was the investigation of the planets Uranus and Neptune and Saturn's moon Titan using adaptive optics imaging and spectroscopy at the 10-meter W.M. Keck Telescopes. These bodies share a common type of atmosphere, one that is rich in methane and has a hydrocarbon haze layer produced by methane photolysis. Neptune and Uranus have atmospheric features which change on short timescales; we have investigated their altitude, composition, and connection to events occurring de… more

Historical Sulfur Dioxide Emissions 1850-2000: Methods and Results

Description: A global, self-consistent estimate of sulfur dioxide emissions over the last one and a half century were estimated by using a combination of bottom-up and best available inventory methods including all anthropogenic sources. We find that global sulfur dioxide emissions peaked about 1980 and have generally declined since this time. Emissions were extrapolated to a 1{sup o} x 1{sup o} grid for the time period 1850-2000 at annual resolution with two emission height levels and by season. Emissions … more

Automated Image Data Exploitation Final Report

Description: The automated production of maps of human settlement from recent satellite images is essential to detailed studies of urbanization, population movement, and the like. Commercial satellite imagery is becoming available with sufficient spectral and spatial resolution to apply computer vision techniques previously considered only for laboratory (high resolution, low noise) images. In this project, we extracted the boundaries of human settlements from IKONOS 4-band and panchromatic images using spe… more

Plasma-Assisted Coevaporation of S and Se for Wide Band Gap Chalcopyrite Photovoltaics: Phase II Annual Report, December 2002--December 2003

Description: In this work, ITN Energy Systems (ITN) and lower-tier subcontractor Colorado School of Mines (CSM) explore the replacement of the molecular chalcogen precursors during deposition (e.g., Se2 or H2Se) with more reactive chalcogen monomers or radicals (e.g., Se). Molecular species are converted to atomic species in a low-pressure inductively coupled plasma (ICP). Tasks of the proposed program center on development and validation of monatomic chalcogen chemistry, tuning of low-pressure monomer chal… more

Simple Derivation of the Hauser-Feshbach and Weisskopf-Ewing Formulae, with Application to Surrogate Reactions

Description: The analysis of surrogate reactions, an indirect technique for determining cross sections on unstable nuclei, relies heavily on compound-nuclear reaction models. The purpose of this tutorial is to provide an introduction to the principal models, based on the Hauser-Feshbach and Weisskopf-Ewing formalisms, and to show how they are applied to surrogate reactions.

Progress Report FY04 Quarter 1

Description: In this quarter, a simulation has been carried out to validate the FEM model for a production facility mill configuration, focusing on the shape change evolution of the slab. Results of ingot shape evolution for a 13 pass rolling simulation are given in Figure 1. It was observed that the rollover of the slab is strongly dependent on friction. More studies on friction laws may be necessary for more accurate prediction. Another important feature is the mesh dependence of the result. More frequent… more
