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 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) ...

ICE PHOBIC COATING MATERIAL, CURRENTLY USED BY THE U.S. NAVY SURFACE SHIPS OPERATING IN ARCTIC REGIONS AND NORTH AATLANTIC, IS ENVIRONMENTALLY UNSTABLE, PRASITIC, AND SACRIFICIAL IN NATURE. THIS PAPER PRESENTS A TECHNICAL APPROACH IN THE DEVELOPMENT OF A DIFFERENT TYPE OF TOP COAT/PAINT THAT IS ENVIRONMENTALLY STABLE, MAINTENANCE FREE WITH BUILT-IN RESISTANCE TO ICE AND FROST ACCERTION OR FORMATIO ...

Standard U.S. Navy fiber optic assemblies require that the fiber be bonded to the connector using an adhesive that is labor intensive and heat controlled (MIL-A-24792). Advanced Material Systems (AMS) proposes a study that could solve this problem through the development of an adhesive system that would cure at room temperature in less that 3 minutes and yet meet all of the in-service req ...

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 ...
