In this proposal, we will develop a uniform framework, called a multimedia mediator, for integrating and querying multimedia data as well as heterogenous data located on a distributed network. The multimedia mediator will use distributed computing technology to scale up to real-world applications. We will develop graphical query languages and query engines whereby an end-user can query a system ...

Avionics flight tests are critical for evaluating weapon systems in operational environments not cost-effectively emulated in flight test. This proposal is for an AATEAS designed to provide the tools necessary to obtain optimal results during avionics testing using established techniques in various test environments. The core of the AATEAS is the Master Workstation (AMWS). This is a mini/macro com ...

A discrete event computer simulation will be developed and used to evaluate the expected performance of the UHF satellite communications Automatic Demand Assignment Multiple Access (Auto-DAMA) Subsystem. Phase I will describe UHF DAMA traffic scenarios, define design requirements for the Auto-DAMA computer model and develop a model of fundamental , single channel Auto-DAMA operations. Phase II wil ...

A stratified random sampling technique is used to minimize the time until detection of users of illicit drugs. The stratification is based on likelihood of drug use and importance of the billet occupied. Likelihood of drug used is calculated from fundamental characteristics (e.g., age, sex, education), performance, health and behavior (e.g., relative amount of sick leave, unusual behavior) ...

The project addresses the development of a 64K Massively Parallel P rocessor (MPP) accelerator board together with OS software for installation on a HP-748 workstation providing generation of real-time, high-fidelity, high pixel density and high refresh rate graphic images. The MPP board will be based on associative string processors (ASPs) in a modular massively parallel computer (MPC) ar ...

AeroSoft, Inc. proposes to develop, incorporate and validate transition and anisotropic turbulence models for improving the low-Reynolds number predictions for high-lift airfoil configurations. The turbulence-modeling package will use Menter's two equati

HIGH PREMEABILITY AND LOW POWER LOSS HEAD THE REQUIREMENTS LAID DOWN FOR A GOOD CORE MATERIAL FOR INDUCTANCE COILS AND TRANSFORMERS FOR THE APPLICATION IN HIGH EFFICIENCY POWER SUPPLY. RECENTLY FERRITE MATERIALS, SUCH AS NICKEL-ZINC-COBALT (NIZNCO) FERRITES HAVE BEEN USED FOR TRANSFORMER AND INDUCTOR CORES BECAUSE OF THEIR HIGH RESISTIVITIES AND CONSEQUENT LOWER EDDY CURRENT LOSSES. HOWEVER, THESE ...
