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 ...

Accelerator Technology Corp. proposes to develop a compact, cost-effective elctron-beam disinfestation system for pasteurization of meat patties. The system is designed to be integrated into the production line of a conventional meat patty operation. In such operations, the patties are stamped from sheets of ground meat in rows of 4-5 patties, moving on a conveyor at the rate of ~1 row/second. ...

Cured aircraft composite materials present a particularly difficult challenge for recycling technology. Those materials have mostly thermosetting epoxy matrices and occur in intimate association with metals, paints, and coatings. Current techniques for recycling thermoset composites, mostly for automotive sheet molding compounds (SMC), involve pulverizing the material for use as fillers. Th ...

A novel tertiary recycling process is proposed for investigation as an economical means for recycling shipboard plastic waste. Early development work has shown that this process can convert a wide variety of polymers and composites into low molecular weight hydrocarbons at temperatures below 200'C. The hydrocarbons produced can then be reused as chemicals, fuels, or monomers. Metal, glass, and fil ...

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 ...

THE PROPOSED RESEARCH IS DIRECTED TOWARD THE IMPROVEMENT OF THE RELATIONSHIPS USED DURING THE EARLY STAGES OF U.S. NAVY AIRCRAFT CARRIERDESIGN FOR ESTIMATING WEIGHTS, VERTICAL CENTERS OF GRAVITY (KG) AND REQUIRED AREAS AND VOLUMES. THE PRINCIPAL FOCUS WILL BE ON UPDATING THE RELATIONSHIPS USED IN THE NAYSEA AIRCRAFT CARRIER DESIGN-SYNTHESIS MODEL. SPECIFIC OBJECTIVES WILL BE AS FOLLOWS: (A)TO PROV ...

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 ...
