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 ...

Events including the Oklahoma CIty bombing and the Sarin attack in the Tokyo subway have emphasized the vulnerability of personnel, both military and civilian, to unexpected attack with conventional explosives and chemical substances. To combat this threat requires portable, low cost sensor systems capable of detecting a variety of dangerous materials at extremely low concentrations. Such a tech ...

AN INNOVATIVE RF EM MODULATION RADAR SENSOR IS PROPOSED WHICH WILL PROVIDE A RICH, MULTI-SPECTRAL RESPONSE FROM RELOCATABLE STRATEGIC TARGETS. THIS NOVEL RF SYSTEM HAS THE FOLLOWING MAJOR ADVANTAGES OVER COMPETING RADAR SYSTEMS. A. IN ADDITION TO PROVIDIG THE CONVENTIONAL RADAR RETURN, A SECONDARY PHASE MODULATION IS INTRODUCED WHICH PROVIDES A UNIQUE RESPONSE CAPABLE OF FURTHER TARGET CHARACTERIZ ...

DECISION SCIENCE CONSORTIUM, INC. (DSC) PROPOSES TO ENGAGE IN AN INNOVATIVE RESEARCH PROGRAM TO DESIGN AND IMPLEMENT AN ADVERSARIAL PLANNING SYSTEM THAT IS ABLE TO REASON ABOUT THE PERSISTENCE OVER TIME OF AN ADVERSARY'S BELIEF AND INTENTIONS. SPECIFICALLY, THIS SYSTEM WILL UTILIZE EITHER A NONMONOLITHIC SITUATIONAL OR TEMPORAL LOGIC TO DETERMINE THE EXTENT TO WHICH AN ADVERSARY'S PRESENT BELIEFS ...

THE DEVELOPMENT OF NEW AND INNOVATIVE TECHNIQUES WHICH DETERMINE ELECTROMAGNETIC SCATTERING BEHAVIOR ARE NECESSARY IN ORDER TO ADVANCE THE STATE-OF-THE-ART IN RADAR CROSS SECTION (RCS) CONTROL. TWO OF THE MORE IMPORTANT ANALYTICAL PROBLEMS REQUIRING SOLUTION IN THIS AREA ARE THE CHARACTERIZATION OF RADAR SCATTERING FROM COMPOSITE MATERIALS AND OPTIMUM APPLICATION OF MATERIAL COATINGS TO METALLIC S ...

A PROJECT IS PROPOSED TO INVESTIGATE THE FEASIBILITY OF COMBINING A PHASE-CHANGE NON-LINEAR OPTICAL MATERIAL WITH A PHOTOREFRACTIVE MATERIAL IN THIN LAYERS TO ACHIEVE A THREE DIMENSIONAL MASS STORAGE MEDIUM. ORGANIC COMPOUNDS POSSESSING GOOD POLARIZABILITY ALONG WITH COMPOSITION CONDUCIVE TO PHASE CHANGE MECHANICS WILL BE TESTED FOR SHG AND PHASE CHANGE ABILITY, THEN PREPARED IN THIN FILMS ON PHOT ...
