DTRA uses high-resolution mesoscale forecasts to drive HPAC, the DTRA dispersion modeling tool that generates critical forecasts of dosage resulting from releases of chemical, biological, or radiological agents. HPAC is designed to provide probablistic information based on estimates of the uncertainty of the input forecast fields of the meteorological variables (wind, temperature, etc.). ...

U.S. forces working in low-level radiation environments have unsatisfactory choices for monitoring radiation exposure. The currently available A/UDR-13 pocket dosimeter is able to meet sensitivity requirements, but is cost prohibitive at ~$400 per unit, and it fails in the high temperature environments faced our military. Careful monitoring and accurate reporting of the exposed dose will reduce t ...

Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Prevention of the spread of nuclear weapons has reached a state of heightened urgency in recent years, especially since the events on September 11, 2001 and its aftermath. Gamma ray spectrometers are an important tool in checking the proliferation of the nuclear weapons. Important re ...

The Defense Threat Reduction Agency has expressed the need for waterborne transport and dispersion capability to compliment its existing models for Chemical, Biological, Radiological and Nuclear (CBRN) releases. DTRA's current capability is limited to the atmospheric transport of CBRN agents using the HPAC system. The objective of this proposed Phase I study is to couple Applied Science Associat ...

Conventional weapons rely on blast and fragmentation as the primary defeat mechanism, whereas non-energetic payloads rely on other means to defeat the target. Non-energetic weapons may defeat targets by the dispersion of aerosols (solid or liquid) or gases to interact with critical target elements. The objective is to cause some combination of denial, disruption, degradation, or destruction witho ...

It is proposed to achieve partial conversion of the visible emission spectrum of burning aluminum into the ultraviolet range. This work is motivated by the search for effective means to defeat biological weapons by munitions employing ultraviolet germicidal radiation (UVGI). It is proposed that aluminized thermobaric formulations can be modified to deploy airborne particulates with nonlinear opt ...

Discontinuous graphite fiber reinforced aluminum magnesium matrix composite with microscopically dispersed add-on oxidizer coating is proposed for the application of enhanced lethality munitions. The composite with the coating is light-weight and reactive, which will generate high reaction temperature and a large amount of reaction heat. The composite also has sufficient mechanical strength for ...

In line with the DOT's desire to encourage the development of a wireless brake shoe force measurement system, Mide will use its extensive experience on loadcell design, energy power-harvesting and wireless data transmission to develop an accurate system for the self-powered, wireless measurement of brake shoe forces on Railroad freight cars. Piezo or coil/magnet proof mass devices will harvest vi ...

NOVA Scientific will demonstrate a large-area/low-cost neutron detection system having high neutron sensitivity with very high signal-to noise ratio. The approach utilizes an embedded neutron absorber in a solid state detector based upon known Microchannel Plate (MCP) processing technology. The system detects concealed fissionable materials located several meters away, by converting the neutron si ...

Physical Sciences Inc (PSI) is working with the NYSEARCH suborganization of the Northeast Gas Association (NGA) to develop the Proactive Infrasonic Gas Pipeline Evaluation Network (PIGPEN) system to detect and warn of third-party damage before it occurs. PIGPEN uses low frequency seismic/acoustic (0.1 to 100 Hz) sensor technology to proactively detect and warn of unauthorized activity near the un ...
