Combining a Multithreaded Scene Graph System with a Tiled Display Environment
This case study highlights the technical challenges of creating an application that uses a multithreaded scene graph toolkit for rendering and uses a software environment for management of tiled display systems. Scene graph toolkits simplify and streamline graphics applications by providing data management and rendering services. Software for tiled display environments typically performs device and event management by opening windows on displays, by gathering and processing input device events, and by orchestrating the execution of application rendering code. These environments serve double-duty as frameworks for creating parallel rendering applications. We explore technical issues related to interfacing scene graph systems with software that manages tiled projection systems in the context of an implementation, and formulate suggestions for the future growth of such systems.

Comparison of Sensitivity Analysis Techniques in Monte Carlo Codes for Multi-Region Criticality Calculations
Recently, sensitivity and uncertainty (S/U) techniques have been used to determine the area of applicability (AOA) of critical experiments used for code and data validation. These techniques require the computation of energy-dependent sensitivity coefficients for multiple reaction types for every nuclide in each system included in the validation. The sensitivity coefficients, as used for this application, predict the relative change in the system multiplication factor due to a relative change in a given cross-section data component or material number density. Thus, a sensitivity coefficient, S, for some macroscopic cross section, {Sigma}, is expressed as S = {Sigma}/k {partial_derivative}k/{partial_derivative}{Sigma}, where k is the effective neutron multiplication factor for the system. The sensitivity coefficient for the density of a material is equivalent to that of the total macroscopic cross section. Two distinct techniques have been employed in Monte Carlo radiation transport codes for the computation of sensitivity coefficients. The first, and most commonly employed, is the differential sampling technique. The second is the adjoint-based perturbation theory approach. This paper briefly describes each technique and presents the results of a simple test case, pointing out discrepancies in the computed results and proposing a remedy to these discrepancies.

Complex interfacial flows. Final report for period August 1, 1997 - July 31, 2001
The objective of this grant was to study complex interfacial flows. Here we report on several problems considered. In particular we have investigated the motion of a liquid along a second liquid interface, we have investigated a canonical problem associated with the rupture of a viscous interface, we have investigated the dynamics of a gas bubble or drop in an inclined parallel walled channel under gravity with and without the presence of surfactants, we have studied the dynamics of a dry spot in a thin liquid film and we have developed a numerical code to study the dynamics of a liquid interface in a parallel walled channel. In addition, two students have completed their Ph.D. thesis during this grant period.

Computational Design Studies for an Ion Extraction System for the Oak Ridge National Laboratory ECR Ion Source
A three-electrode system for optimally extracting, high-intensity, multi-charged ion beams from an all-permanent-magnet, ''volume''-type, ECR ion source, has been computationally designed. Beams of highest quality and transportability are extracted whenever the angular divergence is minimum. Under this condition, the plasma boundary has an optimum curvature, the angular divergence is consequently minimum; the perveance, the extraction gap, and the current density each have optimum values. Results obtained from computational simulation studies of the extraction optics are found to closely agree with those derived from elementary analytical theory for extraction of space-charge-dominated beams.

Computer Generated Inputs for NMIS Processor Verification
Proper operation of the Nuclear Identification Materials System (NMIS) processor can be verified using computer-generated inputs [BIST (Built-In-Self-Test)] at the digital inputs. Preselected sequences of input pulses to all channels with known correlation functions are compared to the output of the processor. These types of verifications have been utilized in NMIS type correlation processors at the Oak Ridge National Laboratory since 1984. The use of this test confirmed a malfunction in a NMIS processor at the All-Russian Scientific Research Institute of Experimental Physics (VNIIEF) in 1998. The NMIS processor boards were returned to the U.S. for repair and subsequently used in NMIS passive and active measurements with Pu at VNIIEF in 1999.

Congressional Overrides of Presidential Vetoes
The President's veto authority is among their most significant tools in the legislative dealing with Congress. It is effective not only in preventing the passage of legislation undesirable to the President, but also as a threat, sometimes forcing Congress to modify legislation before it is presented to the President. As of the writing of this document, Presidents had vetoed 1,484 bills and Congres had overridden only 106 of them. This report details what bills have been vetoed by President Clinton and how they were vetoed.

Congressional Overrides of Presidential Vetoes
The President’s veto is effective not only in preventing the passage of legislation undesirable to the President, but also as a threat, sometimes forcing Congress to modify legislation before it is presented to the President. However, as a veto threat is carried out, Congress is faced with choices: letting the veto stand, the difficult task of overriding the veto, meeting the President’s objections and sending a new bill forward, or resubmitting the same provisions under a new bill number.

Cookoff Response of PBXN-109: Material Characterization and ALE3D Thermal Predictions
Materials properties measurements are made for the RDX-based explosive, PBXN-109, and initial ALE3D model predictions are given for the cookoff temperature in a U.S. Navy test. This work is part of an effort in the U.S. Navy and Department of Energy (DOE) laboratories to understand the thermal explosion behavior of this material. Benchmark cookoff experiments are being performed by the U.S. Navy to validate DOE materials models and computer codes. The ALE3D computer code can model the coupled thermal, mechanical, and chemical behavior of heating, ignition, and explosion in cookoff tests. In our application, a standard three-step step model is selected for the chemical kinetics. The strength behavior of the solid constituents is represented by a Steinberg-Guinan model while polynomial and gamma-law expressions are used for the Equation Of State (EOS) for the solid and gas species, respectively. Materials characterization measurements are given for thermal expansion, heat capacity, shear modulus, bulk modulus, and One-Dimensional-Time-to-Explosion (ODTX). These measurements and those of the other project participants are used to determine parameters in the ALE3D chemical, mechanical, and thermal models. Time-dependent, two-dimensional results are given for the temperature and material expansion. The results show predicted cookoff temperatures slightly higher than the measured values.

Coulometric Titration of Microgram Amounts of Americium at the Conducting Glass Electrode
Coulograms of Am(III) in carbonate electrolyte exhibit a well-defined wave for the Am(III)-Am(V) oxidation step at the conduction glass electrode. This wave provides the basis of a method for the quantitative titration of this element at the 30-microgram level with a precision of 1.5 percent. The method is restricted to pure solutions; corrections are required for the partial oxidation of Am(V) to Am(VI) and the reduction of Am(VI) by water.

Cuba: U.S. Restrictions on Travel and Legislative Initiatives in the 107th Congress
Since the United States imposed a comprehensive trade embargo against Cuba in the early 1960s, there have been numerous policy changes to restrictions on travel to Cuba. The embargo regulations do not ban travel itself, but place restrictions on any financial transactions related to travel to Cuba, which effectively result in a travel ban. This report reflects legislative or other major developments , including a listing and discussion of legislative initiatives in the 107th Congress.
