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 ...

Accuwave Corporation has developed a narrow bandwidth (1/8 angstrom) optical imaging filter operating in the red. A critical need exists for narrow bandwidth imaging filters with a wide field of view. In this proposed research effort, Accuwave filter technology will be extended to a wider field of view using multimple holograms stored in a LiNb03 crystal.

Accuwave Corporation will study the feasibility of a volume holographic, phase-encoded optical image correlator for credit card and document validation and security application. Fourier transform holograms of a phase-encoded input image are stored using wavelength multiplexed holographic gratings in a photorefractive crystal. High spatial resolution images can be sotred with low crosstalk using ...

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 ...

Currently, airbreathing propulsion systems which operate in the subsonic to high supersonic regime are expensive, complex and heavy. To overcome these limitations, a novel propulsion concept based on a liquid hydrocarbon-fueled Pulse Detonation Engine (PDE) is proposed. The innovation draws from recent successes in computational fluid dynamics and from several engineering studies and PDE develop ...

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 ...

The use of commercially available technology for military hardware either as it exists off-the-shelf or with slight modification presents a large opportunity for cost saving in both the non-recurring development cost and the recurring cost of production and maintenance of military hardware. This may allow for the development of new, extremely cost effective weapon systems on an expedited schedule ...
