FASTMAN PROPOSES TO UTILIZE THE ADAPTIVE WAVELET TRANSFORM (AWT) TO DECOMPOSE SPEECH SIGNALS INTO THEIR INTEGRAL, INFORMATION-BEARING COMPONENTS FOR USE AS A PREPROCESSOR FOR PATTERN RECOGNIZERS. FOR A GIVEN SIGNAL, FAST-MAN'S ADAPTIVE WAVELET TRANSFORM SELECTS THE BASIS WHICH PRODUCES THE MOST CONCENTRATED REPRESENTATION OF THE SIGNAL IN WHICH MOST OF THE INFORMATION IN A SIGNAL IS "COMPRESSED" I ...

AN ADVANCED ENDOTHERMIC FUEL REACTOR (AER) IS PROPOSED WHICH UTILIZES A UNIQUE HEAT PIPE CONFIGURATION TO TRANSFER HEAT FROM HOT COMPONENTS OF A HYPERSONIC PROPULSION SYSTEM TO ENDOTHERMIC FUEL. THIS INNOVATIVE CONCEPT RESPONDS TO THE HIGH MACH COMBINED CYCLE ENGINE TECHNOLOGIES TOPIC IN THE AREA OF ENDOTHERMIC FUEL REACTOR/ENGINE INTEGRATION AND HEAT EXCHANGERS. PROJECT OBJECTIVES ARE: TO ESTABLI ...

INTERCONNECTIONS BETWEEN LOGIC BLOCKS PLAY AN INCREASINGLY IMPORTANT ROLE IN TODAY'S HIGH PERFORMANCE MICROCIRCUIT DESIGNS. PERFORMANCE VIOLATIONS DUE TO INTERCONNECT EFFECTS SUCH AS PROPAGATION DELAYS, DISPERSION, ATTENUATION, RINGING, REFLECTION AND CROSSTALK MUST BE DETECTED BEFORE A DESIGN IS COMMITTED TO PRODUCTION. THE RECENTLY DEVELOPED ASYMPTOTIC WAVEFORM EVALUATION (AWE) TECHNIQUE PROMISE ...

AstroPower will develop a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51 In(0.49)P, which is lattice matched to GaAs, as the top cell in a three-junction, two-terminal tandem solar cell. This new tunable bandgap Al-Ga-In-P material is capable of current matching in a two-junction monolithic tandem solar cell two-terminal design of the Al-Ga-In-P over GaAs yielding a best case ...

AstroPower is developing a highly sensitive UV detector based on epitaxial AlGaP/GaP heterostructures, a promising new material system for ultraviolet detectors. Detecting ultraviolet light is important to spectrophotometry, astronomy, high-energy physics, medicine, UV curing, photoresist exposure, and chemical processes. The large bandgap and crystalline quality of gallium phosphide will provide ...

MANY GOVERNMENT WEAPONS TESTING FACILITIES SUCH AS THE KWAJALEIN MISSILE RANGE DEPEND ON C BAND TRACKING RADARS SUCH AS THE AN/FPQ-19 TO PROVIDE ANGLE TRACKING AND RANGE DATA DURING MISSILE TESTS. THESE TYPES OF RADARS ARE STILL THE PRIMARY INSTRUMENTS USED FOR TEST SUPPORT, ALTHOUGH THE STATE OF THE ART HAS ADVANCED SINCE THESE RADARS WERE FIELDED. ONE LIMITATION OF THESE RADARS IS A CUMBERSOME T ...

A COMPREHENSIVE RESEARCH STUDY, LEADING TO THE DEVELOPMENT OF A NOVEL SAPPHIRE-FIBEROPTIC SENSOR, FOR HIGH TEMPERATURE TESTING OF COMPOSITE TURBINE ENGINES IN "REAL" ENVIRONMENTS, IS PROPOSED. THE SENSOR WILL OPERATE ON THE PRINCIPLE OF MODAL POWER DISTRIBUTION (MPD) MODULATION IN MULTIMODE SAPPHIRE FIBERS CAUSED BY THERMAL AND MECHANICAL STRESSES IN THE SMART MATERIALS. THE STRATEGY FOR THE PROPO ...
