There is an urgent need to procure for our military forces on the ground in Iraq and in other locations technology and equipment which provide the capability to effectively and immediately detect, assess, and defend against the threat from Improvised Explosive Devices (IEDs). It is believed that this same threat, applied to Weapons of Mass Destruction (WMD) dispersal, could also increasingly beco ...

The potential for progressive collapse of buildings damaged by terrorist blasts represents a significant risk to building occupants. There is a need for software tools that assess the potential for progressive collapse of above ground structures. These tools should run quickly and accurately predict the collapsed region of a damaged structure. These tools would be of great value to security pla ...

Presently, commercial and government radiation test facilities do not have convenient, reliable calibration systems for routine, day-in, day-out checks on x-ray and neutron detectors or their filter arrays. Lack of such calibration systems compromises the quality of the testing, and leads to wasted time and manpower resources used to resolve the ensuing uncertainties. We are developing a compact, ...

It is proposed to produce and evaluate hybrid powders containing highly reactive filler coated by or embedded into a matrix of readily boiling, combustible binder. The binder material, such as paraffin wax and Viton-like rubber, are expected to ignite and burn within the expanding fireball while the reactive filler remains at the relatively low temperature at which the binder boils, and thus rema ...

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 ...

The complexity of Atmospheric Transport and Dispersion (ATD) modeling requires physically consistent weather data evolving in both space and time. Spatially and/or temporally averaged data found in climatological products is not suitable for ATD modeling. The proposed solution for providing "typical day" meteorological data couples innovative search techniques applied to long-range historical arch ...

In this proposed Phase II program we will build on the successful Phase I program where we for the first time implemented engineered epitaxial layers based on nanostructure technology that were used to harden commercial silicon devices against radiation by minimizing collected photocurrents (electron-hole pairs) via recombination centers where we demonstrated that improved radiation hardness could ...

For ultra high-speed, ultra low-power applications in DoD space and weapons systems, devices and circuits fabricated from III–V semiconductor compounds offer significant advantages over silicon-based technology. However, the uncertainty in single-event-effect (SEE) response of compound semiconductor technologies forces the use of empirically-based hardening techniques with penalties in increased ...
