NUTRIENT SOLUTIONS USED IN HYDROPONIC PLANT GROWING FACILITIES (SUCH AS NASA'S CELSS) SHOULD BENEFIT FROM ON-LINE MEASUREMENT AND CONTROL OF THE IONIC CONCENTRATIONS OF THE NUTRIENTS THAT MAKE UP SUCH SOLUTIONS. BIOTRONICS HAS DEVELOPED AN ON-LINE FIBER-LINKED FLUOROMETRIC ANALYZER POTENTIALLY CAPABLE OF MEASURING THESE IONIC CONCENTRATIONS. THIS FIBER-OPTIC BASED FLUOROMETRIC ANALYZER, DESIGNATED ...

AN OPERATIONAL DEMONSTRATION OF THE TECHNICAL FEASIBILITY OF A HIGH TEMPERATURE SMALL TURBOJET ENGINE IS PROVIDED BY THIS PROGRAM. THIS DEMONSTRATION CONFIRMS THAT A CERAMIC RADIAL TURBINE WHEEL CAN WITHSTAND THE SHORT DURATION HIGH TEMPERATURE EXPOSURE REQUIRED OF A SMALL TACTICAL MISSILE ENGINE. SINCE THE TURBINE WHEEL IS THE MOST CRITICAL CERAMIC COMPONENT OF A NEW HIGH TEMPERATURE ENGINE, THE ...

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 ...

A NUMBER OF ORGANOPHOSPHORUS COMPOUNDS ARE HIGHLY TOXIC AS A RESULT OF THEIR ABILITY TO INHIBIT CHOLINESTERASES. THIS TOXICITY HAS LED TO THE WIDESPREAD USE OF THESE COMPOUNDS AS PESTICIDES AND SUGGESTS THEIR POTENTIAL USE AS AGENTS OF CHEMICAL WARFARE. A NUMBER OF BACTERIAL SPECIES ELABORATE ENZYMES, TERMED ORGANOPHOSPHORUS ACID (OPA) ANHYDRASES, CAPABLE OF DETOXIFYING THESE COMPOUNDS. THE GOALS ...

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 ...

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 ...
