Hazard assessment tools that model the transport and dispersion of Chemical, Biological, Radiological, Nuclear and Explosive (CBRNE) materials through urban areas are only as good as the 3D models that inform the physics model. Maintaining accurate, up-to-date 3D models of urban areas is challenging. Even in the commercial world, urban construction and demolition may result in the models created a ...

To Counter Weapons of Mass Destruction (CWMD), DTRA must analyze data from numerous sources about a diverse set of technologies and activities. The extreme diversity in content and the volume of DTRAs data combine to produce one of the most challenging analysis problems in the government. The CWMD mission therefore requires deep analysis - an in-depth understanding of all available data and correl ...

Plasma from AB donors is considered universal as it can be transfused regardless of recipient blood type and is frequently used to rapidly resuscitate massively bleeding hospital trauma patients and warfighters with combat casualties. However supplies can be rapidly depleted as AB donors make up only 4% of the population. Therefore robust a technology to cost-effectively generate universal plasma ...

At the completion of the research and development effort a Li-foil multi-wire proportional counter (MWPC) neutron detector with more than 625-cm2 of active area will be included in a portable radiation detection system. The system is expected to outperform the standards set by the ANSI N42.53 standards, and gamma-ray rejection ratio (GRR) of 1.0x10-8 or better. A gamma-ray spectrometer for isotope ...

Phase II will utilize knowledge gained from phase I work to develop and execute a manufacturing process suitable for producing quantities of 3-D printed discrete circuits for radiation detection systems.  The goal is to support mobile radiation detection system requirements for high voltage, analog amplification, and MCA functionality to produce differential pulse height spectra in time sequence. ...

Nalas Engineering and Johns Hopkins University collaborated in a Phase I STTR program to study reactive mixtures of HI3O8 and nanocomposite fuels previously developed by the Weihs Group. These fuel/oxidizer mixtures are uniquely able to simultaneously produce heat and biocidal iodine gas, a combination designed to destroy biological weapons. The team at Nalas focused on evaluating conditions for p ...

Control of extremely lightweight, long endurance aircraft poses a challenging aeroservoelastic (ASE) problem due to significantly increased flexibility, and aerodynamic, structural, and actuator nonlinearities. To obtain the benefits of increased aerostructural efficiency, the controller needs to trim at a specified optimal shape while minimizing structural fatigue from gust disturbances. Tao Syst ...

NanoSonic has developed revolutionary multifunctional, super lightweight, self-healing and radiation shielding carbon fiber reinforced polymer (CFRP) composites as a viable lightweight material for space applications such as primary or secondary structures on NASA vehicles, habitat modules, and pressure vessel structures. While current composites are lightweight, they do not offer reliable method ...

Inflatable pressurized habitats are envisioned as a practical way to build shelters much larger than landing craft for astronauts and their scientific operations on Mars, the moon and elsewhere. These habitats maintain their inflated shape via high-strength Vectran webbing. The piezoresistive extensometers developed through this STTR program can be directly integrated into or onto Vectran webbing ...

During the NASA program, we will transition the semiconductor nanomembrane self-calibrating cryogenic and minimum pressure sensors from their current concept and prototype TRL 4-5 demonstration stage, to near-term instrumentation products of use to NASArsquo;s propulsion system facilities, other NASA instrumentation programs, academic researchers and industrial technologists. NanoSonic will again ...
