Acoustic and seismic sensors have become the technology of choice for Unattended Ground Sensors. Military vehicles have loud and distinctive signatures which can be detected at remarkable distances. In order to minimize the size and cost of the proposed sensors, SenTech proposes to use a single microphone and a three component geophone as the sensor's transducers. SenTech's proposals incorporat ...

THE OBJECTIVE OF THE PHASE I RESEARCH IS TO DETERMINE THE TECHNICAL FEASIBILITY OF THE DEVELOPMENT OF A LONG RANGE RADIOACTIVE PLUME TRANSPORT MODEL/CODE FOR THE NRC. THIS CODE WOULD BE USED TO SIMULATE THE MOVEMENT, DISPERSION, DECAY, AND DEPOSITION OF RADIONUCLIDES RELEASED FROM SEVERE NUCLEAR REACTOR ACCIDENTS, SUCH AS THE CHERNOBYL ACCIDENT. IT IS DESIRED THAT ALL RELEVANT PHYSICAL AND CHEMICA ...

MOCVD IS A UNIVERSALLY ACCEPTED EXPITAXIAL PROCESS FOR THE DEPOSITION OF COMPOUND SEMICONDUCTORS. IN FACT, MANY PRODUCTION FACILITIES ARE IN OPERATION. PRODUCTS INCLUDE MICROWAVE AND MILLIMETER WAVE INTEGRATED CIRCUITS (MMICS), LASER DIODES FOR COMPACT DISC PLAYERS, PHOTOCATHODES FOR NIGHT VISION GOGGLES, AND GALLIUM ARSENIDE AND INDIUM PHOSPHIDE SOLAR CELLS. THE CRITICAL WEAKNESS OF THE MOCVD TEC ...

Spire and its subcontractor, Westinghouse/Norden Systems, propose development of color, thin film electroluminescent (TFEL) head mounted displays (HMDs) using passive matrix addressing and indium bump-bonded drive electronics. Passive matrix addressing vastly simplifies fabrication and improves manufacturing yields by decreasing the number of high voltage drive transistors required for display op ...

A demonstration of Broadband Code Division Multiple Access (CDMA) for PCS communications overlaid in the 800 MHz AMPS cellular band will be conducted. Broadband CDMA using direct sequence spread spectrum has significant military advantages of jamming immunity and low probability of intercept. It is also the most promising of the new concepts for high capacity commercial cellular radio because of ...

Capturing the rationale behind decision making in design plays an important role to explain a design, redesign and/or reuse an existing design. Existing design rationale models suffer from the lack of integrating rationale with the design process. The integration is crucial for the domain of software design due to its complexity. A model for design rationale capture and its related knowledge ba ...

This work offers an innovative approach to predicting system behavior (in terms of reliability and performance) based primarily on the structural characteristics of a formal functional specification. The mechanism for process composition is codified in the CSP-to-Stochastic Petri net (CSPN) toll. CSPN supports systematic specification, automatic translation and subsequent augmentation (e.g., fai ...
