We propose to develop practical video libraries allowing users to quickly find useful material. Commercial, home, or surveillance video programming captures information in multiple tracks: picture, sound, and closed captioning. Using multiple modalities cataloging information, visual information, and audio information is critical since no one track contains necessary information to identify clip ...

This Phase I project has two primary objectives. The first objective is to develop an engineering model of Resonant Tunneling Devices (RTD) to be implemented in AIM-Spice, a commercial software package running under Windows 95/NT. The development of a reliable device model is a prerequisite for the design and production of any semiconductor device technology. The RTD model will be a semi-empiri ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

The proposed research combines an innovative eigenvector method with other electromagnetic techniques to produce a hybrid approach towards solving the EM coupling to satellite cavity problem. The physical structure is divided into an exterior region and one or more interior regions. The exterior region is modeled with method of moments (MOM) and or hybrids of MOM with the uniform theory of diffr ...

AeroSoft proposes the development of efficient and accurate Computational Fluid Dynamics methods for calculating the airflow characteristics over complex bodies with time-dependent, Reynolds-Averaged, Navier-Stokes equations which have been augmented to allow for dynamic meshes as well as non-equilibrium chemistry and thermodynamics. The dynamic-mesh approach proposed here is based on ...

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

In response to the DOD request to design and develop novel catalysts to facilitate the synthesis of energetic materials and commercially viable products, it is proposed to undertake a detailed molecular modeling studies on the structures of various zeolites and the binding of organic compounds and inorganic cations with these zeolites. New force field will be developed for these zeolites suitabl ...
