PREDICTING THE RATE OF SOIL WATER MOVEMENT AND THE IMPACT OFAGRI-CHEMICALS ON WATER RESOURCES IS VITALLY IMPORTANT TO MANAGING AGRICULTURE, FOR OPTIMIZING PRODUCTIVITY AND MINIMIZING ENVIRONMENTAL IMPACT. SOPHISTICATED MODELS FOR MAKING SUCH PREDICTIONS ARE AVAILABLE, BUT DATA ON SOIL HYDRAULIC PROPERTIES ARE DIFFICULT AND OFTEN EXPENSIVE TO OBTAIN. IN FACT, AT DEPTHS BELOW THE ROOT ZONE THERE IS ...

THE HANDING AND STORAGE OF AIRCRAFT FUELS, ROCKET PROPELLANTS AND SOLVENTS AT AIR FORCE INSTALLATIONS CREATES THE POTENTIAL FOR ACCIDENTIAL RELEASE OF AIRBORNE POLLUTANTS. CURRENTLY AVAILABLE DISPERSION MODELS FOR PLANNING AND RESPONSE ACTIONS DO NOT EFFECTIVELYADDRESS BUILDING EFFECTS. THE OBJECTIVES OF THIS STUDY, THEREFORE, ARE TWOFOLD: (1) TO ASSESS FOR A RANGE OF RELEASE SCENARIOS THE SIGNIFI ...

LARGE, PERIODIC TEMPERATURE EXCURSIONS CAUSE SIGNIFICANT DIMENSIONAL CHANGES IN LARGE ORBITING SPACE STRUCTURES. SIMILARLY, LARGE GROUND-BASED ANTENNAS AND OPTICAL SYSTEMS ARE SUBJECT TO DIURNAL DIMENSIONAL CHANGES THAT DIMINISH PRECISION AND SENSITIVITY. OUR RECENTLY DEVELOPED GRAPHITE/MAGNESIUM METAL MATRIX COMPOSITES (MMC) HAVE BEEN SHOWN TO BE DIMENSIONALLY STABLE (ZERO CTE AND ZERO HYSTERESIS ...

THE PERFORMANCE TRANSFER FROM A TRAINING SIMULATOR TO THE OPERATIONAL EQUIPMENT IS DIRECTLY RELATED TO THE FIDELITY OF THE SIMULATOR. SUBTLE CHANGES IN THE RELATIVE DYNAMIC, MOTION AND/OR VISUAL SYSTEM PERFORMANCE CAN BE DETECTED BY THE TRAINEE RESULTING IN ADVERSE PHYSICAL REACTIONS (OFTEN REFERRED TO AS "SIMULATOR SICKNESS"), AND CORRESPONDING DEGRADATION IN THE TRAINING EFFECTIVENESS. THE ADVEN ...

THE CONCEPT FOR A BULK OPTICALLY-CONTROLLED SEMICONDUCTOR SWITCH (BOSS), WHERE TWO DIFFERENT WAVELENGTH LASERS ARE USED TO GENERATE AND QUENCH PHOTOCONDUCTIVITY WAS RECENTLY INTRODUCED BY SCHOENBACH AND LAKDAWALA AT OLD DOMINION UNIVERSITY (ODU). INSTEAD OF SUSTAINING PHOTOCONDUCTANCE BYLASER LIGHT, AS IN CONVENTIONAL PHOTOCONDUCTIVE SWITCHES, ONE LASER IS USED TO DRIVE THE SWITCH INTO A CONDUCTIV ...

ALGORITHMS FOR FUSING AND DISPLAY OF ACTIVE AND PASSIVE SENSOR INFORMATION IN THE AIRBORNE TACTICAL ENVIRONMENT ARE OUTLINES. FUSION AND DISPLAY IS PARTITIONED INTO TRACK EXTRAPOLATION, OBSERVATION UPDATE, CORRELATION, GRIDLOCK, ERROR MANAGMENT, AND USER INTERACTION. METHODS OF TESTING THE TOTAL PROCESS WITH SENSOR DATA SIMULATION, CONFLICT SIMULATION, AND MEASURES OF EFFECTIVENESS ARE DISCUSSED.

THE PROPOSED EFFORT WILL DEVELOP AND APPLY A NEW EXPERIMENTAL APPROACH TO MEASURE UNDERWATER TIME RESOLVED SHOCK WAVE PROFILES RESULTING FROM UNDERWATER OR SURFACE DETONATIONS. EXPLICIT DATA REQUIRED TO DESCRIBE UNDERWATER SHOCK WAVE EFFECTS ON TARGETS WILL BE OBTAINED USING A RECENTLY DEVELOPED PIEZOELECTRIC POLYMER STRESS GAUGE. A UNIQUE EXPERIMENTAL CONFIGURATION IS PROPOSED, THAT WILL ALLOW SH ...
