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 ...

A MODEL FOR PREDICTING THE PERFORMANCE IMPACT OF ENGINE DETERIORATION IS PROPOSED FOR FEASIBILITY EVALUATION. THIS MODEL WOULD ACCOUNT FOR ROTATING COMPONENT DETERIORATION SUCH AS INCREASED TIP CLEARANCES, SURFACE ROUGHNESS, LEADING EDGE BLUNTNESS AND VAN BOW AND TWIST. THE PROPOSED APPROACH USES A STAGE STACKING METHOD TO ALLOCATE LOSSES THROUGHOUT THE ENGINE WHICH ARE DEPENDENT ON OPERATING TIME ...

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 ...

MASSIVELY INTERCONNECTED COMPUTERS, COMMONLY CALLED NEUROCOMPUTERS, ARE AT THE HEART OF SIXTH-GENERATION COMPUTING. TO DATE, HOWEVER, ONLY NEUROCOMPUTER SIMULATORS AND EMULATORS ARE AVAILABLE. THIS RESEARCH PROJECT WILL DEVELOP TOOLS AND TECHNIQUES TO TRANSLATE NEUROCOMPUTERS INTO COMPUTATIONALLY EQUIVALENT DIGITAL VLSI CIRCUITS. CONCEPTS FROM SWITCHING CIRCUIT THEORY WILL BE USED TO TRANSLATE IND ...

THE ABILITY TO GROW HETEROSPITAXIAL THIN FILMS OF DIAMOND IS LIMITED IN PART BY THE PROPENSITY OF SUCH FILMS TO NUCLEATE AT MULTIPLE SITES WITHOUT PROPER ORIENTATION. WE PROPOSE TO DEVELOP A 2-DIMENSIONAL GROWTH PROCESS BY ATOMIC LAYER EPITAXY (ALE) USING ADVANCED MOLECULAR BEAM TECHNIQUES. THE PHASE I RESEARCH WILL FOCUS ON DETERMINING THE MICROCHEMISTRY OF DEPOSITION PROCESSES AND THUS ALLOW FOR ...

THE POLARIZATION CHARACTERISTICS OF AIRCRAFT INFRARED SIGNATURES HAVE BEEN STUDIED AS A MEANS TO ENHANCE THE PERFORMANCE OF LONG RANGE PASSIVE INFRARED DETECTION SYSTEMS OPERATING IN THE PRESENCE OF CLUTTER. THESE STUDIES ALSO GENERATED EVIDENCE THAT THE AMOUNT AND ANGLE OF POLARIZATION AS WELL AS ITS SPATIAL DISTRIBUTION ARE UNIQUE BETWEEN DIFFERENT TYPES AND CLASSES OF AIRCRAFT. IT MAY BE POSSIB ...

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

Existing materials used for marine cable connectors each have drawbacks in terms of cost or performance. Alden Products Company proposes a program to develop a family of cable connectors and adapters that lower the present cost/performance barrier in two ways; through the use of alternative materials and through new manufacturing methods using the existing materials. The main goals of P ...

MODERN MILITARY OPERATIONS HAVE MADE IT NECESSARY FOR COMMANDERS TO HAVE RADIOLOGICAL INFORMATION CONCERNING NUCLEAR CONTAMINATION OF OCCUPIED AREAS. THIS INCREASING NEED FOR MORE ACCURATE AND RELIABLE INFORMATION FOR THE PURPOSE OF LOCATING AND IDENTIFYING POTENTIALLY HAZARDOUS NUCLEAR SOURCES, HAS LED TO NEED FOR IMPROVED INSTRUMENTATION. IN PARTICULAR, A NUCLEAR SURVEY INSTRUMENT WITH IMAGING C ...
