THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...

HIGH RANGE (200,000 G) ACCELEROMETERS ARE THE ONLY TRANSDUCERS THAT PROVIDE THE REQUIRED LONG-TERM DATA IN THE ENVIRONMENTS OF INTEREST TO THE BLAST AND SHOCK COMMUNITY. THESE GAGES HAVE A VERY LARGE DYNAMIC RANGE AND NOISE OFTEN MASKS THE LATE TIME (BUT EXTREMELY IMPORTANT) DATA. WE PROPOSE TO DEVELOP A CLOSE COUPLED LOGARITHMIC GAIN SIGNAL CONDITIONING SYSTEM THAT WILL CORRECT THE LATE TIME NOIS ...

Not Available Paper recycling continues to increase in the United States, with public support and legislative mandates helping boost recycling of all paper grades. Office waste paper is a significant source of high grade paper fiber for recycling, but is currently underutilized, due to the challenges of fully removing xerographic and laser printer toner. These so called *laser inks* are designed t ...

Commercially available tents and vestibules are relatively inaccessible to people who use mobility devices or those with dexterity limitations. The objectives of this project are to develop and test tent-related technology which results in a vestibule and a combined tent and vestibule accessible to people of varying abilities, including people with mobility, dexterity, cognitive and visual impairm ...

THE ENVIRONMENT SURROUNDING CONFINED ANIMALS DIRECTLY AFFECTS THE PRODUCTIVITY OF THE LIVESTOCKINDUSTRY. A GOOD VENTILATION SYSTEM, WHICH CONTROLS THIS ENVIRONMENT, IS ESSENTIAL FOR MANTAINING THE HEALTH AND WELFARE OF ANIMALS AND WORKERS IN THE LIVESTOCK BUILDINGS. HOWEVER, THE DESIGN AND MANAGEMENT OF SUCH A SYSTEM IS A COMPLICATED PROCESS. IT INVOLVES OPTIMIZATION OF VARIOUS GOVERNING PARAMETER ...

CURRENT NUMERICAL COMPUTATIONS TO DESCRIBE NUCLEAR GROUND SHOCK ENVIRONMENTS, NUCLEAR CRATER FORMATION, IMPACT DYNAMICS AND PENETRATION MECHANISMS PRESENTLY EMPLOY EULERIAN-BASED FINITE DIFFERENCE CODES BECAUSE OF THEIR ABILITY TO MODEL THE MASS FLUX PHENOMENA IN TRACKING MATERIAL MOVEMENT THROUGH THE DISCRETIZED SPACE. THE FINITE DIFFERENCE CODES SUFFER IN COMPARISON TO FINITE ELEMENT CODES, HOWE ...

"Reflex triode bremsstrahlung sources potentially provide warm X-ray sources (20 keV to 500 keV), capable of generating high doses (~10 cal/g gold) over exposure areas of ~20 cm2. This needed capability allows experimental verification of warm X-ray inducedthermomechanical response, SGEMP, and box IEMP models for achieving component and system certification to hostile environments.In a reflex trio ...

PROGRESS IN DEVELOPING NUTRITIONALLY IMPROVED MAIZE HAS SUFFERED DUE TO THE LACK OF A SIMPLE, RAPID AND INEXPENSIVE METHOD FOR ASSESSING BREEDING PROGRESS. METHODS TO DATE HAVE GENERALLY INVOLVED THE USE OF VISIBLE VARIANTS SUCH AS OPAQUE WITH ASSOCIATE QUALITY/YIELD DEFICIENCIES OR COMPLEX/EXPENSIVE ANALYTICAL METHODS SUCH AS AMINO ACID ANALYSIS. WE PROPOSE TO DEVELOP AN IMMUNOLOGICAL DIAGNOSTICF ...
