An interactive application that employs social interactions to teach key social conventions, including appropriate responses, reacting to body language and facial expressions, and the ability to ask for help to facilitate functioning in society

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 ...

The objective of the proposed program is to develop a portable, low-cost, label-free (reagentless), microarray system capable of near real-time simultaneous detection and identification of multiple analytes (bacteria, viruses, spores, toxins) with high sensitivity and low false alarm rate. Notably, the system will be capable of detection/identification of agents on the basis of protein and/or nuc ...

This program will provide an improved understanding of the effects of atmospheric moisture on hazardous material and define methods to better model these effects in the DTRA HPAC model. The work will evaluate the interaction of moisture and hazardous material in the HPAC model based on two levels of coupling the transport equations for hazardous material and moisture. These evaluations will be com ...

Penetrating radiation holds the greatest promise as a non-intrusive means of destroying biological and chemical agents inside sealed containers, if the appropriate form is used. There are two recognized means including exposure to neutrons or application of pulses of gamma rays. Because of the pervasiveness of neutrons and the extremely large threat of collateral damage to humans, neutrons are onl ...

Nuclear weapons effects simulators depend upon capacitor banks for storage and delivery of energy for the radiation sources. Power conditioning elements are typically located in the power flow chain between the storage capacitors and the radiation sources, and these elements generally constitute a major portion of the overall cost of the simulator facility. Low inductance capacitors offer the po ...

DEVELOPMENT OF AN INNOVATIVE AND ECONOMICAL EXPERIMENTAL METHOD IS PROPOSED WHICH CAN PROVIDE THE BASIC BEHAVIOR DATA NECESSARY TO MEET THE DNA OBJECTIVE OF PROVIDING ADEQUATE ANALYSIS, DESIGN AND ASSESSMENT METHODS FOR MINIMALLY HARDENED TUNNELS. THIS DEVELOPMENT IS ACCOMPANIED BY ANALYSIS CAPABLE OF REPRESENTING THE COMPLEX INELASTIC MATERIAL BEHAVIOR OF THE ROCK MASS AND OF REPRESENTING SIMPLE ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP AN IMPROVED DIFFERENTIAL PRESSURE GAGE FOR DETERMINING DYNAMIC PRESSURE WITHIN BLAST AND SHOCK WAVE FLOWS WHERE THE FLOWS ARE SUBSONIC. DERIVATION OF DYNAMIC PRESSURE FROM A MEASUREMENT OF THE DIFFERENCE BETWEEN STAGNATION PRESSURE AND SIDE-ON OR STATIC PRESSURE REQUIRES USE OF THE SIDE-ON PRESSURE RECORD TO CORRECT FOR COMPRESSIBILITY EFFECTS. CURRENTLY ...
