A surface film instrumentation (SuFI) system will be developed to measure, in real time, vortex dynamics using advanced non-intrusive hot-film sensors. An innovative 5-element hot-film sensor design will be used to determine the surface streamline direction resulting from the off-surface, three-dimensional vortical flows. Wind-tunnel tests will be conducted on a generic double-delta wing model ...

The proposed research is directed toward demonstrating the feasibility of manufacturing refractory matrix continuous fiber-reinforced ceramic composites (RM-CFCCs) by Polymer Infiltration/Pyrolysis (PIP) processing. RM-CFCCs are currently produced only by Chemical Vapor Infiltration (CVI) which is very costly and time consuming. PIP processing is a simple extension of the methods used to manufactu ...

The SC-21 Program Office faces an unprecedented challenge in the capture and analysis of information required to take Ship Information System (SIS) architecture from concept through to development, deployment, upgrade, and retirement. The principal objective of the system development process is to establish a design which satisfies the system requirements and constraints while optimizing the key ...

The cost of system acquisition within the Department of Defense is significantly greater then other areas such as research and training. The acquisition of major DoD systems currently takes approximately 20 years from concept to service. The introduction and application of modern modeling and simulation, supported by all the advances in hardware and communication technologies, could conceiva ...

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 ...

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 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 ...
