With infrastructure costs escalating it is becoming essential to monitor the health of asphalt and concrete pavement so that timely maintenance can maximize their usefulness. This SBIR will develop a sensor that can be embedded within concrete or asphalt, which can measure moisture, temperature, stress and strain. It will provide critical data for evaluating pavement performance starting with th ...

Applied Nanotech, Inc. (ANI) proposes to develop a novel neutron generator based on electron impact ionization from a carbon nanotube (CNT) electron source. Our proposed approach is aimed at providing significant advantages for man-portable or UAV deployment. It will provide significant advantages over existing neutron or gamma-ray sources in terms of size, weight and power efficiency without co ...

WHEELCHAIR OCCUPANTS ARE EXTREMELY VULNERABLE TO INJURY IN EVEN MODERATE SPEED CRASHES BECAUSE OF THE OPEN ENVIRONMENT IN WHICH THEY ARE BEING TRANSPORTED TODAY. IT IS COMMON PRACTICE TO TRANSPORT THE WHEELCHAIR BOUND POPULATION FACINGSIDEWAYS IN VANS AND BUSSES. THIS SIDE-FACING ORIENTATION EXPOSES THE WHEELCHAIR OCCUPANT TO A DISPROPORTIONATE AMOUNTOF DANGER IN THE EVENT OF FRONTAL OR REAR-END C ...

Algorithms are needed for fast-running engineering models that predict damage levels of structural members subject to the blast environment from high explosives detonated inside a building (i.e., internal explosions). These algorithms will be used as part of vulnerability analyses that quickly assess building blast damage from internal explosion scenarios associated with terrorist threats, mission ...

Rail vehicle distance traveled measurements don't currently meet the precision requirement of 5ft./mile. An innovative microwave technique is proposed using two X band transceiver assemblies separated by a known distance. Reflected energy from metal objects such as tie-plates or dielectric contrast between ties and rail bed are used as replicate pairs to measure the time passage between transcei ...

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 ...

An approach for performing high fidelity modeling for blast and progressive collapse simulations of buildings will be developed. The modeling approach will allow complete simulations of building response to be performed within several days of computing time on desktop PCs. An 'easy to use' modeling interface will also be demonstrated in this effort. All response regimes will be addressed includi ...

AN IBM PC-COMPATIBLE AIR TRAFFIC CONTROL SIMULATOR WITH VOICE I/O, AN EXTENSIVE DATABASE OF GEOGRAPHICAL FIXES, AND CONFLICT RESOLUTION VIA AN EXPERT SYSTEM IS PROPOSED. THIS SIMULATOR WILL BE DESIGNED TO FACILITATE AIRSPACE DESIGN ANDPROCEDURE DEVELOPMENT. CAPABLE OF DISPLAYING A REALTIME RADARSCOPE PICTURE OF ANY GEOGRAPHICAL AREA, ITS SECTORS MAYBE CREATED VIA A SIMPLE USER INTERFACE BY FIELD P ...
