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 ...

Software is a mature discipline, yet more than 98 percent of all PCs have one or more vulnerable programs, and in the US there are 2.7 billion programs open for attack. Efforts to address the problem at the source --during software development--are shockingly inadequate, with many commercial Software Assurance tools focused on detection rather than working to become part of the development process ...

The Department of Homeland Security's charter has a fundamental requirement to collaborate with other government agencies. Secure collaboration on this scale requires strong identity management which can "vouch for" DHS personnel working with other agencies, and makes it possible to provide DHS resources to individuals in other agencies whose work requires it. We propose the development of a reu ...

The current generation of advanced static-analysis tools find vulnerabilities by exploring all possible executions of a program as configured for a single platform. The next quantum leap in capability will be a system that will explore all executions for many different platforms simultaneously. We propose to develop such a system by combining a number of state-of-the-art techniques. Novel continuo ...

We propose to build a system that combines novel automatic test generation techniques with state-of-the-art multi-platform continuous integration technology. The proposed system will automatically generate test data by using a combination of symbolic and concrete executions to intelligently explore the space of inputs. The continuous integration technology will enable the system to detect defects ...

With the range and variety of radiation detectors that exist and the continuing threat of a radiological disaster in the future, the need for training of first responders and personnel in the front lines of interdiction is extraordinary and daunting. It is daunting because of the number of people across the nation that must be trained initially and who must continually maintain their training to b ...

This SBIR Phase I will model and physically demonstrate wearable, small factor, and lightweight thermoelectric generator prototypes powered by human body heat. The project will make use of Perpetua`s novel Flexible Thermoelectric Film technology to yield higher voltages and power from small active areas. End devices will be in wearable form factors, including a flexible button array that can be in ...

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 ...

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 ...
