The preponderance of biosensors under development today rely on labeling reagents such as fluorescent, radioisotopic or enzymatic tags. As a result, the added complexity of these reagents and their incorporation into the detection system has resulted in designs that are difficult to implement or that require significant sample preparation steps before introduction into the detection instrument. ...

Shelter enclosures for military working dogs in the event of a CB attack is a technology gap identified by the Joint Requirements Office. Important parameters to consider in the design of protective enclosures include low weight and size to minimize transport requirements; rapid setup; and accommodation of canine physiological and psychological comfort needs while providing protection against CB ...

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 ...

We propose to demonstrate the feasibility of a novel ultra-high-speed (UHS) infrared spectrometer that will operate as an essential component of Thermal Luminescence systems for standoff detection of surface contaminants. The proposed spectrometer will be able to detect transient thermal events in the fundamental vibrational fingerprint region of chemical warfare agents and of most toxic industria ...

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 ...

Current geopolitical strategies require effective warfare countermeasures to protect U.S. forces against biological and chemical threats. Today's molecular biology and immunological detection technologies cannot be used to produce automated biodetectors useable in the battlefield. New, improved detection technologies are needed to minimize the impact of chemical and biological weapons on Army per ...

Ktech proposes to develop a HV2A methodology for the assessment of nuclear weapon effects on new materials that are candidates for inclusion in strategic and tactical military systems. The methodology (1) provides an estimate of the system requirements and operation environments for each application specific material/structure, (2) establishes the critical response modes, (3) provides a framework ...

ADVANCED STRUCTURAL MATERIALS USED IN THE FABRICATION OF SUBMARINES CAN SUSTAIN LARGE STRAINS DURING THE FORMATION PROCESS CAUSED BY EXPLOSIVE LOADINGS. THE COMPUTATIONAL SOLID MECHANICS COMMUNITY HAS RECENTRLY RECOGNIZED SERIOUS SHORTCOMINGS IN CALCULATIONS USING MATERIAL MODELS IN THIS LARGE STRAIN REGION. BECAUSE OF THE IMPORTANCE OF CALCULATIONS IN UNDERSTANDING THE SHOCK RESPONSE OF SUBMARINE ...

Weidlinger Associates Inc. proposes to develop effective technology for simulating explosive detonations within civil buildings where the propagation of airblast and failure of weak internal walls are strongly coupled. We will conduct a field test program designed to complement other internal detonation testing efforts such as DTRA''s Distinct Cobra, expanding the available database. We will perfo ...
