ABSTRACTION OF DRIFT SEEPAGE

Description: Drift seepage refers to flow of liquid water into repository emplacement drifts, where it can potentially contribute to degradation of the engineered systems and release and transport of radionuclides within the drifts. Because of these important effects, seepage into emplacement drifts is listed as a ''principal factor for the postclosure safety case'' in the screening criteria for grading of data in Attachment 1 of AP-3.15Q, Rev. 2, ''Managing Technical Product Inputs''. Abstraction refers to… more

Adaptive path planning algorithm for cooperating unmanned air vehicles

Description: An adaptive path planning algorithm is presented for cooperating Unmanned Air Vehicles (UAVs) that are used to deploy and operate land-based sensor networks. The algorithm employs a global cost function to generate paths for the UAVs, and adapts the paths to exceptions that might occur. Examples are provided of the paths and adaptation.

Almost Optimal Interior Penalty Discontinuous Approximations of Symmetric Elliptic Problems on Non-Matching Grids

Description: We consider an interior penalty discontinuous approximation for symmetric elliptic problems of second order on non-matching grids in this paper. The main result is an almost optimal error estimate for the interior penalty approximation of the original problem based on the partition of the domain into a finite number of subdomains. Further, an error analysis for the finite element approximation of the penalty formulation is given. Finally, numerical experiments on a series of model second order … more

Alternative Minimum Tax: Overview of Its Rationale and Impact on Individual Taxpayers

Description: Testimony issued by the General Accounting Office with an abstract that begins "This testimony focuses on the Alternative Minimum Tax (AMT), its interaction with the regular tax system, and its projected growth in coverage. GAO found that (1) AMT was designed to ensure that high-income individuals do not avoid significant income tax liabilities--for tax year 1997, about 14,000 taxpayers would not have paid any income taxes absent AMT, (2) AMT operates as a separate tax system that parallels the… more

AMRSim: an object-oriented performance simulator for parallel adaptive mesh refinement

Description: Adaptive mesh refinement is complicated by both the algorithms and the dynamic nature of the computations. In parallel the complexity of getting good performance is dependent upon the architecture and the application. Most attempts to address the complexity of AMR have lead to the development of library solutions, most have developed object-oriented libraries or frameworks. All attempts to date have made numerous and sometimes conflicting assumptions which make the evaluation of performance of … more

Analysis and testing of rupture of steam generator tubing with flaws.

Description: A high-temperature (300 C), high-pressure (18 MPa), and high-leak rate (1500 L/min) facility, and a room temperature, high-pressure (52 MPa) test facility were used to test flawed steam generator tubes. Single and multiple rectangular flaws were fabricated by electro-discharge machining on the outside surface of the tubes. This paper briefly reviews analytical methods for predicting ligament rupture and unstable burst of tubes with single and multiple rectangular flaws. Test data are presented … more

Assessment of General Atomics accelerator transmutation of waste concept based on gas-turbine-modular helium cooled reactor technology.

Description: An assessment has been performed for an Accelerator Transmutation of Waste (ATW) concept based on the use of the high temperature gas reactor technology. The concept has been proposed by General Atomics for the ATW system. The assessment was jointly conducted at Argonne National Laboratory (ANL) and Los Alamos national laboratory to assess and to define the potential candidates for the ATW system. This report represents the assessment work performed at ANL. The concept uses recycled light water… more

Assessment of On-Site Power Opportunities in the Industrial Sector

Description: The purpose of this report is to identify the potential for on-site power generation in the U.S. industrial sector with emphasis on nine industrial groups called the ''Industries of the Future'' (IOFs) by the U.S. Department of Energy (DOE). Through its Office of Industrial Technologies (OIT), the DOE has teamed with the IOFs to develop collaborative strategies for improving productivity, global competitiveness, energy usage and environmental performance. Total purchases for electricity and ste… more

Asymptotic technique for the far field pattern of a dipole in an infinite stratified medium

Description: Modern antennas especially arrays are being placed in layers of materials on complex environments. This technique produces aesthetically pleasing structures if necessary, allows for more freedom in structure planning, and can improve antenna performance. In the past, buried antennas have been studied by numerous authors such as in Reference. Recent work on this subject uses spectral and/or numerical moment method formulations. For high frequency analysis it is important to find efficient and ac… more

Axions from wall decay

Description: The authors discuss the decay of axion walls bounded by strings and present numerical simulations of the decay process. In these simulations, the decay happens immediately, in a time scale of order the light travel time, and the average energy of the radiated axions is <w{sub a}> {approx_equal} 7m{sub a} for v{sub a}/m{sub a} {approx_equal} 500. <w{sub a}> is found to increase approximately linearly with ln(v{sub a}/m{sub a}). Extrapolation of this behavior yields <w{sub a}> {… more

Beam stability issues of the VLHC rings

Description: Beam stability issues of the VLHC rings in Phase 1 and Phase 2 are reviewed. For accelerator rings of circumference 232 km and beam pipe radius of the order of 1 cm, the impedance of the vacuum chamber is dominated by the resistive wall. The most dangerous instabilities are the single-bunch transverse mode coupling instability and the transverse coupled bunch instability driven by the resistive wall at sub-revolution frequency. Scaling is studied concerning the thresholds of these instabilities… more

Benchmarking optimization software with COPS.

Description: The COPS test set provides a modest selection of difficult nonlinearly constrained optimization problems from applications in optimal design, fluid dynamics, parameter estimation, and optimal control. In this report we describe version 2.0 of the COPS problems. The formulation and discretization of the original problems have been streamlined and improved. We have also added new problems. The presentation of COPS follows the original report, but the description of the problems has been streamlin… more

Best Practices: Better Matching of Needs and Resources Will Lead to Better Weapon System Outcomes

Description: A chapter report issued by the General Accounting Office with an abstract that begins "This report examines how best practices offer improvements to the way the Department of Defense defines and matches weapon system requirements to available resources such as cost, schedule, and mature technologies. GAO identified three factors that were key to matching needs and resources before product development began. First, developers employed the technique of systems engineering to identify gaps between… more

Budget Issues: Agency Data Supporting Capital Project Funding Requests Could Be Improved

Description: A letter report issued by the General Accounting Office with an abstract that begins "During its review of 2001 agency budget justifications, GAO found several capital project funding requests that lacked total project cost information and for which it was not always clear whether requested funding would provide a useful, stand-alone asset. Without this information, Congress cannot consider the full costs of proposed commitments or determine if it is funding an asset that will be useful without… more
