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 Equity capital markets are unorganized or non-existent in rural areas with most capital directed outward. Emerging growth companies have difficulty obtaining equity capital - precisely the kind of companies that rural America must develop to increase earnings or workers. The key to attracting investment of capital and know-how to rural areas is to create regionally-based organization ...

Introduction of aquatic nuisance species (ANS) by ballast water poses a significant ecological and economical threat to the United States harbors. Open ocean exchange of ballast water outside the exclusive economic zone (EEZ) in waters greater than 2000 meters deep is the primary method used to reduce this threat. To verify that ballast exchange has occurred, the United States Coast Guard needs ...

Not Available The United State Department of Agricultural (USDA) and the Animal and Plant Health Inspection Services (APHIS) in conjunction with other Federal and State Organizations, have conducted a number of integrated pest management programs to eradicate various types of household pest including Red Imported Fire Ants (RIFA). Recent programs have involved application of products such as Malat ...

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 ...

Sclerotinia sclerotiorum, or white mold, is a resilient and devastating disease that has emerged as a significant threat to many of the broadleaf crops of the United States. Sclerotinia is known to infect about 408 species of plants. It has been estimated to cause hundreds of millions of dollars in losses annually to the United States' dry edible bean, sunflower, canola, and soybean crops. The dis ...
