The proposed approach considers test program development as a consequence of building a functional model of the UUT using a black box approach. This is accomplished through a revolutionary new approach to test and measurement equipment that brings the testinstrument directly to the UUT pin and circuit path, virtually eliminating signal path loss and problems associated with the lack of test points ...

The need for innovative combined cycle engines for Space Access and hypersonic vehicles leads the Air Force design engineers to the requirement for analysis tools that provide higher levels of fidelity than are available today. The engines for thesevehicles, rather than being separate systems, are integrated systems that share inlets, nozzles and in many cases, combustor flow paths. Because analyt ...

The efficient, intuitive use of ultrasonic inspection techniques is critical in assuring that motor cases (as well as other components) are manufactured and maintained correctly. Present inspection methodology generally uses a point-by-point scan of theitem that can be very time consuming with results that are not easily interpreted. In Phase I, the feasibility of using a wide-area ultrasonic im ...

Surface Treatment Technologies, proposes the development of innovative structural explosive material systems based upon the formation of structural nano-grained reactive alloys formed via electron-beam deposition. Electron-beam deposition has beendeveloped as a method of rapidly forming nano-grained structures with a high degree of functional gradations throughout a structure. These include the ...

Signal diversity combining is a powerful signal processing technique that significantly improves the link quality of satellite or wireless communications.A powerful application example is to increase the transmission speed of a mobile user terminal equipped with a low-gain antenna. As the user terminal transmits a signal through a hemispheric coverage antenna, the signal is received by multiple sa ...

Phase II design, fabrication and fielding of an advanced electric pick up truck which incorporates Li-Ion Polymer, high-density batteries. This truck is a zero-emission service vehicle with double the operation range of current,similar electric trucks.Target markets are DOD bases, utilities and municipalities in non-attainment areas, universities, pollution endangered areas (such as Napa valley) a ...

THE GLOBAL POSITIONING SYSTEM (GPS) SATELLITES TRANSMIT INFORMATION ON TWO FREQUENCIES IN THE L-BAND: L(1) AT 1575.42 MHZ AND L(2) AT 1227.6 MHZ. THESE TWO TRANSMISSIONS ARE PHASE-COHERENT SINCE THEY ARE DERIVED FROM A COMMON OSCILLATOR. BOTH OF THESE FREQUENCIES ARE MODULATED BY A P-CODE CONSISTING OF PSEUDO-RADOM ONE'S AND ZERO'S. THE TRANSMISSION RATE IS 10.23 MHZ AND THE CODE ON BOTH THE TRANS ...

WE PROPOSE THE DEVELOPMENT OF A COMPUTER-BASED INTELLIGENT INSTRUCTIONAL DESIGN SYSTEM (IIDS) THAT WILL ACT AS AN ADVISOR TO THE INSTRUCTIONAL DESIGNER CONCERNING EDUCATIONAL THEORY AND PRINCIPLES. THE IIDS WILL BE BASED ON CONTEMPORARY COGNITIVE AND INSTRUCTIONAL SCIENCE PRINCIPLES AND WILL TAKE ADVANTAGE OF CURRENT TECHNOLOGIES WITHIN THE FIELD OF ARTIFICIAL INTELLIGENCE. THE IIDS WILL BE A STRU ...

REDUCTION OF SATELLITE RADIANCE DATA TO TEMPERATURE PROFILES INVOLVES BOTH DIFFICULT MATHEMATICAL INVERSION ANALYSIS AS WELL AS COMPLICATED DATA PROCESSING. RECENTLY, THE APPLICATION OF THE OPTICAL MEASURE THEORY REPRESENTS A NOVEL APPROACH WHICH PROVIDE A SOLUTION FREE FROM THE NEED OF EXTERNALLY-IMPOSED CONSTRAINTS (KING, 1987). THE OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP A SYSTEMATIC TECHNICAL ...

RESEARCH WILL BE CARRIED OUT TO DEMONSTRATE THE UNIQUE VALUE OF CHEMICALLY BONDED CERAMICS (CBC) AS MATERIALS FOR FABRICATION OF MECHANICAL DETERRENTS TO SYMPATHETIC DETONATION OF MUNITIONS. CBC MATERIALS WILL BE FORMULATED AND CHARACTERIZED FOR SHOCK ATTENUATING PROPERTIES AND FRAGMENT CAPTURE OR VELOCITY REDUCTION PROPERTIES. THE FINAL MATERIAL IS LIKELY TO BE A BINARY MATERIAL (TWO DIFFERENT TY ...
