A letter report issued by the General Accounting Office with an abstract that begins "State Medicaid programs make a wide variety of payments to individuals, institutions, and managed health care plans for services provided to beneficiaries whose eligibility status may fluctuate because of changes in income. Because of the size and the nature of the program, Medicaid is potentially at risk for billions of dollars in improper payments. The exact amount is unknown because few states measure the overall accuracy of their payments. Some improper Medicaid payments by states are the result of fraud by billers or program participants, but such improper payments are hard to measure because of the covert nature of fraud. Efforts by state Medicaid programs to address improper payments are modestly and unevenly funded. Half of the states spend no more than 1/10th of one percent of program expenditures to safeguard program payments. States also differ in how they help prevent improper payments as well as the degree to which they coordinate their investigations and prosecutions of fraud. Federal guidance to the states relies largely on technical assistance. The Health Care Financing Administration has recently taken a more active role to facilitate states' efforts and provide …

Testimony issued by the General Accounting Office with an abstract that begins "The Veterans' Employment and Training Service (VETS) runs programs and activities designed to help veterans obtain employment and training assistance. Recently, policymakers have advocated changes to the structure and administration of the VETS program and the way it assesses program performance. This testimony discusses VETS' efforts to improve its performance measurement system. VETS has proposed changes to its performance measurement system that will move it closer to implementing an effective accountability system. However, more changes are needed so that VETS can effectively determine whether its programs and services are fulfilling its mission. VETS continues to send a mixed message to states about what services to provide and to whom. In addition, two of the proposed measures may provide nearly identical results, and neither helps VETS to monitor whether more intensive services are being provided to veterans or whether these services are successful. Furthermore, through its planning documents and proposed performance measures, VETS continues to inconsistently identify the groups of veterans that it wants states to help. This testimony summarizes a May report (GAO-01-580)."

Three sets of LX-04 samples of 0.18 and 0.49 mm nominal thicknesses were all dynamically loaded by Sandia's Z-accelerator with a ramp compression wave with a 200 ns rise time and about 150 kb peak stress. The LX-04/lithium fluoride samples interface velocities were measured using VISAR's. Comparisons of experimental and computational results are given. Compression and release isentropes both show some reaction and kinetic behavior of the LX-04. Experiments were also performed on fine-grained TATB. Future experiments on single crystals of HMX that are designed to measure the phase transition at high pressures is discussed.

This document is a slightly expanded version of a portion of the Proton Driver design report. The Proton Driver group gets the credit for the original idea of running an Accumulator experiment in the BTeV era. The work presented here is a study of the feasibility of this idea. The addition of the Recycler Ring to the Fermilab accelerator complex provides an opportunity to continue the program of {bar p}p physics in the Antiproton Source Accumulator that was started by Fermilab experiments E760 and E835. The operational scenario presented here utilizes the Recycler Ring as an antiproton bank from which the colliders makes 'withdrawals' as needed to maintain the required luminosity in the Tevatron. The Accumulator is only needed to re-supply the bank in between withdrawals. When the {anti p} stacking rate is sufficiently high, and the luminosity requirements of the Collider experiments are sufficiently low, there will be time between Collider fills and subsequent refilling of the recycler to deliver beam to an experiment in the Accumulator. In the scenario envisioned here, the impact of the Accumulator experiment on the luminosity delivered to the Collider experiments is very small. If the Run II antiproton stacking rate goals are met, …

This Final Report surveys the work done on understanding the properties and behavior of driven interfaces. It is presented under two topics: (1) interfaces driven in pure and perturbed Hele-Shaw cells; (2) gels, colloids, and polymer solutions as complex media for interface growth and motion. This work has contributed to the international effort to learn about nonlinear and pattern forming systems. The data have been influential as theoretical and computational groups have attempted to understand the dynamics and nonlinear processing steps and the structure-property relations of complex materials. The Hele-Shaw cell was especially productive during this period of intense interest in ''simple'' nonlinear pattern formation, providing the simplest and best understood pattern forming system which could then be complicated with changes of boundary condition or changes of fluid property to test in a controlled way the effect on pattern formation of added physical/mathematical complexity.

Selecting the model is an important and essential step in model based fault detection and diagnosis (FDD). Factors that are considered in evaluating a model include accuracy, training data requirements, calibration effort, generality, and computational requirements. The objective of this study was to evaluate different modeling approaches for their applicability to model based FDD of vapor compression chillers. Three different models were studied: the Gordon and Ng Universal Chiller model (2nd generation) and a modified version of the ASHRAE Primary Toolkit model, which are both based on first principles, and the DOE-2 chiller model, as implemented in CoolTools{trademark}, which is empirical. The models were compared in terms of their ability to reproduce the observed performance of an older, centrifugal chiller operating in a commercial office building and a newer centrifugal chiller in a laboratory. All three models displayed similar levels of accuracy. Of the first principles models, the Gordon-Ng model has the advantage of being linear in the parameters, which allows more robust parameter estimation methods to be used and facilitates estimation of the uncertainty in the parameter values. The ASHRAE Toolkit Model may have advantages when refrigerant temperature measurements are also available. The DOE-2 model can be expected to …

A letter report issued by the General Accounting Office with an abstract that begins "As of August 1, 1999, the Army's Comanche helicopter program faced significant risks related to cost overruns, scheduling delays, and degraded performance. GAO concluded that proceeding to the next development phase with high levels of uncertainty was not in accordance with best practices followed by successful commercial firms. This report evaluates changes since 1999 in the Comanche's cost, schedule, and performance, and assesses whether the Army will have the knowledge it needs to proceed with its current production plans. GAO found that the Comanche program's total development and production cost estimate has increased by almost $4.8 billion. However, areas of high technical risks and unfunded requirements could further increase the program's costs. The program office does not plan to update its April 2000 current estimate to reflect these increases until January 2003. The Comanche's December 2006 full rate production decision date has not changed even though the risks of not meeting this date have increased. The Army continues to face the risk that critical performance requirements may not be met--at least for the helicopters it will initially produce. The Department of Defense (DOD) recently provided $84 …

The atmospheric forecast model of the Naval Research Laboratory's (NRL) Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) has been developed into a parallel, scalable model in a joint collaborative effort with Lawrence Livermore National Laboratory (LLNL). The new version of COAMPS has become the standard model of use at NRL and in LLNL's Atmospheric Science Division. The main purpose of this enterprise has been to take advantage of emerging scalable technology, to treat finer spatial and temporal resolutions needed in complex topographical or atmospheric conditions, as well as to allow the utilization of improved but computationally expensive physics packages. The parallel implementation facilitates the ability to provide real-time, high-resolution, multi-day numerical weather predictions for forecaster guidance, input to atmospheric dispersion simulations, and forecast ensembles.

To replace a hard tube design, a solid-state kicker pulser for the Dual-Axis Radiographic Hydrodynamic Test facility (DARHT-2) has been designed and tested. This kicker modulator uses multiple solid-state modules stacked in an inductive-adder configuration where the energy is switched into each section of the adder by a parallel array of MOSFETs. The modulator features very fast rise and fall times, pulse width agility and a high pulse-repetition rate in burst mode. The modulator can drive a 50{Omega} load with voltages up to 20 kV and can be easily configured for either positive or negative polarity. The presentation will include test and operational data.
