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 AMR across different applications and architectures difficult or impracticable. The evaluation of different approaches can alternatively be accomplished through simulation of the different AMR processes. In this paper we outline our research work to simulate the processing of adaptive mesh refinement grids using a distributed array class library (P++). This paper presents a combined analytic and empirical approach, since details of the algorithms can be readily predicted (separated into specific phases), while the performance associated with the dynamic behavior must be studied empirically. The result, AMRSim, provides a simple way to develop bounds on the expected performance of AMR calculations subject to constraints given by the algorithms, frameworks, and architecture.

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 accurate methods for design purposes. A rigorous recursive method for plane waves reflection and transmission coefficients by Richmond has been used in the past for dipoles above multilayer slabs. This solution is modified in this paper to account for forward and backward traveling rays with appropriate spread factors for a dipole in the media. Extensive validation for this approximate method shows good agreement with a Method of Moments code. This code is developed at Lawrence Livermore National Laboratory. The geometry for these comparisons uses a dipole in nontruncated dielectric multilayer slabs.

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}> {approx_equal} 60 m{sub a} in axion models of interest.

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 streamlined. For each problem we discuss the formulation of the problem and the structural data in Table 0.1 on the formulation. The aim of presenting this data is to provide an approximate idea of the size and sparsity of the problem. We also include the results of computational experiments with the LANCELOT, LOQO, MINOS, and SNOPT solvers. These computational experiments differ from the original results in that we have deleted problems that were considered to be too easy. Moreover, in the current version of the computational experiments, each problem is tested with four variations. An important difference between this report and the original report is that the tables that present the computational experiments are generated automatically from the testing script. This is explained in more detail in the …

This report explores key aspects of the intersection between the nation's clean air and energy goals and proposes alternatives for encouraging renewable energy in the context of the federal Clean Air Act (CAA). As with most environmental statutes enacted in the early 1970s, the 1970 CAA embraced a somewhat rigid ''command-and-control'' approach to achieving its clean air goals. Although effective, this approach has been criticized for discouraging creative and cost-effective solutions to reducing air emissions. In response to this concern, Congress included the first significant market-based program to address an environmental problem-in this case, acid rain caused by sulfur dioxide (SO2) emissions from power plants-in the 1990 CAA Amendments. This program prompted the federal government and various state governments to pursue other market-based programs to address air pollution problems. Ten years have elapsed since the passage of the 1990 CAA Amendments, so the time is ripe to consider expanding opportunities for renewable energy development in the reform of clean air policies. A significant potential for renewables exists in conjunction with international efforts to reduce emissions of greenhouse gases (GHG), including CO2. Unfortunately, Congressional opposition to international GHG reduction agreements makes it difficult to develop GHG emission-reduction programs, including a cap-and-trade …

Correspondence issued by the General Accounting Office with an abstract that begins "This report discusses the use of intellectual property generated at the Department of Energy's (DOE) laboratories to satisfy defense contractors' offset requirements. GAO found that DOE's laboratory offset requirements have been limited. GAO's discussions with DOE and laboratory management contractors uncovered only 14 instances in which the laboratories' intellectual property were involved in offset projects. GAO also found that management contractors have the right to intellectual property that they produce at DOE laboratories."

Correspondence issued by the General Accounting Office with an abstract that begins "GAO examined the military's inventory management activities to determine if activity codes identified as unauthorized to requisition had been used to buy property for the Air Force. GAO found that as of June 2000, the Air Force maintained 4,239 activity codes identified as unauthorized to requisition government property. However, during the last five years, 193 of these codes were inappropriately used to requisition nearly $23 million in new and excess government property. In addition, safeguards established to prevent unauthorized activity codes from being used to requisition government property failed. This situation has created a condition in which government property is vulnerable to waste, fraud, and abuse."

Correspondence issued by the General Accounting Office with an abstract that begins "GAO examined Navy inventory management activities to determine whether any unauthorized activity codes had been used to requisition new and excess property. GAO found that as of June 2000, the Navy maintained 2,002 activity codes identified as unauthorized to requisition government property. However, during the last five years, 663 of these codes were used to requisition more than $2 billion in new and excess government property. In addition, there were no safeguards in the Defense Automatic Addressing System Center or the Defense Reutilization and Marketing Service to prevent these activity codes from being used. This has created a condition in which government property is vulnerable to waste, fraud, and abuse."

This report provides technical documentation for values in the Table of Initial Isolation and Protective Action Distances (PADs) in the ''2000 Emergency Response Guidebook'' (2000ERG). The objective for choosing the PADs specified in the 2000ERG was to balance the need to adequately protect the public from exposure to potentially harmful substances against the risks and expenses that could result from overreacting to a spill. To quantify this balance, a statistical approach was adopted, whereby the best available information was used to conduct an accident scenario analysis and develop a set of up to 100,000 hypothetical incidents. The set accounted for differences in the types of containers, types of incidents, severities of accidents (i.e., amounts released), locations, times of day, times of year, and meteorological conditions involved. Each scenario was analyzed by using detailed emission rate and atmospheric dispersion models to calculate the downwind chemical concentrations. The safe distance for each incident, defined as the distance downwind from the source at which the chemical concentration falls below the health criteria, was determined. The health criteria used were the American Industrial Hygiene Association's Emergency Response Planning Guideline Level 2 (ERPG-2) or equivalent criteria. The statistical sample of safe distance values for all …

Title I, Part A of the Elementary and Secondary Education Act (ESEA) authorizes federal aid to state and local educational agencies (SEAs, LEAs) for the education of disadvantaged children. Title I grants are used to provide supplementary educational and related services to low-achieving children attending schools with relatively high concentrations of pupils from low-income families. Services may be provided at pre-kindergarten through high school levels. Title I has been the anchor of the ESEA since it was first enacted in 1965, and is the largest federal elementary and secondary education assistance program.

Correspondence issued by the General Accounting Office with an abstract that begins "As of June 2000, the General Services Administration (GSA) maintained 52 activity codes identified as unauthorized to requisition government property. During the last five years, four of these codes were inappropriately used to requisition about $3,000 in new and excess government property. Although this amount represents a small percentage of total GSA requisitions made during the five-year period, existing safeguards are inadequate to prevent the use of unauthorized activity codes to requisition government property. GSA is now tracing the various items."

The Generalized System of Preferences (GSP) extends duty-free treatment to certain products that are imported from designated developing countries. The primary purpose of the program, which the United States and other industrial countries initiated in the 1970s, is to promote economic growth and development in these countries by stimulating their exports. The program was reauthorized by the 106th Congress, retroactively from July 1, 1999, through September 30, 2001. The 107th Congress will face the issue of whether to reauthorize GSP.
