An objective Canopy Weather Forecast System (CWFS) will be developed and tested. The system willbe based on a site-specific one-dimensional (1-D) soil-canopy-atmospheric boundary layer numericalmodel which is coupled to a three-dimensional (3-D) mesoscale atmospheric numerical model. Theoutput from the CWFS will be designed for input into a variety of models that provide directinformation for cr ...

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 ...

Internal parasites are the greatest health and production challenge for sheep and goats in southeastern states and others during warm, humid conditions (including Northeastern, Midwestern and irrigated pastures in Western US). Haemonchus contortus, or barber pole, worm thrives in warm, humid climates and is a voracious blood feeder that can cause anemia and death to the animal if left untreated. I ...

Future high-performance integrated circuits in DoD satellite systems will require silicon-on-insulator (SOI) and non-planar nano-technology devices, such as MultiGate Field Effect Transistors (MuGFETs) or FinFETs, which can decrease pattern area of logic circuits below 50% of the conventional planar technologies. However, the single-event-effect (SEE) response of non-planar devices and circuits is ...

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 ...

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 ...

The development of a high-shock data recorder for use in projectile penetration and pyrotechnic environments is critical to understanding the loads that warhead systems are exposed to in tactical applications. Data from recorders mounted inside warheads can be used by researchers to measure loads on the warhead, fuze, and explosive fill components as well as validate analytic and computational mo ...

This SBIR Phase II project targets early intervention in math and science for preK-3 students in high need rural areas. The research timeline will design, build and validate a web-based Early Math and Science Preparation and Intervention Program that that trains and develops the underlying facilities required for future math learning. Working in tandem with national leaders in cognitive neuroscien ...

THE INTENT OF DOD INSTRUCTION 4245.4, "ACQUISITION OF NUCLEAR SURVIVAL SYSTEMS" IS TO PROVIDE FOR NUCLEAR SURVIVABILITY THROUGHOUT THE LIFE CYCLE OF WEAPON SYSTEMS WHICH ARE REQUIRED TO SURVIVE THE EFFECTS OF NUCLEAR WEAPONS. ONE KEY TO IMPLEMENTING THIS INTENT IS TO INSURE THAT ALL THE PEOPLE INVOLVED ARE FAMILIAR WITH THEIR RESPONSIBILITIES TO IMPLEMENT AND PRESERVE THIS SURVIVABILITY. THIS STUD ...

A NEWLY CONCEIVED SENSOR USES PULSED RF ENERGY CONDUCTED ALONG THE GROUND SURFACE TO IMMEDIATELY DETECT ANY OBJECT OR PERSON CROSSING A SELECTED AREA. THE SENSING ELEMENT IS THE GROUND ITSELF SINCE GROUND CONDUCTIVITY (RESISTANCE -1) CHANGES WHEN COMPRESSED BY THE WEIGHT OF AN OBJECT. USING ADVANCED SIGNAL PROCESSING TECHNIQUES, THE SENSOR TRANSLATES THE CHANGE IN GROUND CONDUCTIVITY INTO A WARNIN ...
