THERE IS AN INCREASED EMPHASIS ON THE ACOUSTIC SIGNATURES OF GROUND COMBAT VEHICLES DUE TO THE DEVELOPMENT OF NEW AND EFFECTIVE ACOUSTIC TARGET ACQUISITION SYSTEMS. DURING THE DESIGN STAGE OF A GROUND COMBAT VEHICLE, IT IS IMPORTANT TO REDUCE THE NOISE, EMITTED FROM STRUCTURAL COMPONENTS. THEREFORE, THE DEVELOPMENT OF ACOUSTIC PREDICTION SOFTWARE IS ESSENTIAL. WITHIN THIS PROJECT, THEORETICAL TECH ...

THIS PROJECT IS DIRECTED AT PRODUCING A GENERALIZED COMPRESSION MODEL FOR SYSTEMATICALLY TRANSMISSION OF VIDEO INFORMATION AT DECREASING DATA RATES WHILE MAINTAINING MAXIMAL INFORMATION. ALTHOUGH MUCH IS STILL UNKNOWN ABOUT THE HUMAN VISUAL SYSTEM, MAJOR PIECES OF THE PUZZLE HAVE RECENTLY BEEN IDENTIFIED AND CAN BE USED AS A BASIS FOR IMPLEMENTING ADVANCED COMPRESSION MODELS WHICH MAXIMIZE THE AMO ...

MUCH RECENT WORK HAS BEEN FOCUSED ON ELUCIDATING THE POTENTIAL BENEFITS OF USING FUZZY LOGIC AND ADAPTIVE NETWORK DECISION MAKING METHODS. ADAPTIVE METHODS, LIKE BACK-PROPAGATION TAUGHT NEURAL NETWORKS, CAN MAKE IT POSSIBLE TO BUILD COMPLEX DECISION MAKING SYSTEM WHICH AVOID THE "EXPERT SYSTEMS" PROBLEM OF MANUALLY ACQUIRED KNOWLEDGE "CAPTURE." INSTEAD, THESE ADAPTIVE METHODS CAPTURE KNOWLEDGE BY ...

The Phase I goal is to build energy-efficient, compact femtosecond optical sources, and demonstrate diode-pumped lasers that can generate femtosecond pulses via self-modelocking. Only readily available 750-nm diode lasers will be used as pump source. Existing subpicosecond sources are complex devices requiring large, heavy, power-inefficient Argon-ion lasers, Nd:YAG, or similar lasers as primary p ...

THIS PROJECT WILL EXPERIMENTALLY DETERMINE THE FEASIBILITY OF OBTAINING A HIGH-RESOLUTION, THREE-DIMENSIONAL IMAGE OF A SCENE USING AN INNOVATIVE, FOCAL-PLANE PROCESSOR TO PRODUCE A COMPACT OPTICAL SENSOR. THE INNOVATION IS IN THE GATING OF THE IMAGE INTENSIFIER TO DEMODULATE AN AMPLITUDE-MODULATED LASER BEAM. THIS OPTICAL HOMODYNE PROCESS USES FOCAL-PLANE PROCESSING TO ACQUIRE THE THREE-DIMENSION ...

ALTHOUGH SEVERAL OTC OVULATION TESTS EXIST, NON ARE SUITABLE FOR CONTRACEPTION APPLICATIONS BECAUSE THEY DETECT LUTEINIZING HORMONE (LH) WHICH EXHIBITS A PEAK PRECEDING OVULATION BY ONLY 16-36 HOURS. THIS RESEARCH WILL DEVELOP A FERTILE PERIOD PREDICTION SYSTEM BASED UPON THE PRESENCE OF AN INCREASE IN URINARY ESTRONE-3-GLUCURONIDE (E1-G) 5 DAYS PRIOR TO OVULATION AND AN INCREASE IN PREGNANEDIOL G ...

A novel class of postaglandin F2-like compounds formed in vitro or in vivo by a free-radical catalyzed noncyclocxygenase mechanism have recently been discovered. For normal humans. Levels of these compounds (called F2-isoprostanes) range from 5-50 pg/ml plasma and 500-3000 pg/ml urinary creatinine, respectively. The in vivo concentration of F2-isoprostances have been shown to increase dramatically ...

We will develop and market a comprehensive collection of antibodies specific for enzymes that play a significant role in drug metabolism . Availability of specific antibodies will greatly facilitate studies of polymorphisms, species and tissue distribution of drug metabolizing enzymes, and the role of individual enzymes in the metabolism of endogenous and xenobiotic chemicals. Widespread availabil ...
