Organophosphorus chemical warfare nerve agents (OP-CWA) are attractive to terrorist groups and rogue states as an inexpensive and accessible technology for chemical warfare. OP-CWA and organophosphate pesticides cause severe neurological symptoms and death by inhibiting the enzyme acetylcholinesterase (AChE); the resulting excess acetylcholine accumulates and overstimulates the human or animal bo ...

Accurate blast simulations based on first-principles, 3-D hydro-codes require hours on notebook PCs. Graphical processing units (GPUs) offer the potential of drastic reductions in run-times. Typical computational fluid dynamics codes perform of the order of 10-100 operations per memory fetch and store. In order to harness the potential of graphical processing units (GPUs), near-perfect streaming ( ...

Due to the potential detection benefits offered by hyperspectral imaging spectroscopy, this is an area of great interest in terms of early detection of plume threats. The major constraint is in costs of components. Under this SBIR, our team will investigate innovative advances in the integration of uncooled microbolometer technologies to determine the potential for reducing detector cost and com ...

Organophosphate (OP) nerve agents are the most dangerous chemical warfare agents and therefore pose a significant threat. Rapid and exact identification of the OP agent involved in any hazardous material incident could significantly facilitate the administration of the most effective therapeutic and allow for appropriate measures of protection and decontamination, thereby increasing survival of t ...

In peacetime environments, concerns over improbable encounter with agent threats are supplanted by the need to understand and assess the performance status or residual life (RL) capacity of sorbent-based technologies used in Collective Protection (ColPro) systems. Systems such as the M98 and M48A1 run continuously and therefore sample large volumes of outside air over their lifetime. It is well- ...

The goal of this SBIR project is to develop and demonstrate an electrokinetically driven nanofluidic sensor device of the physical size and shape that will allow integration with a THz spectroscopic instrument. The substrate and channel surfaces within the device will be appropriate for the acquisition of THz-frequency spectroscopic features from bio-molecules (e.g., DNA, RNA, proteins) in soluti ...

The proposed Phase II effort investigates innovative finite element formulations, alternative structural modeling procedures and modern parallel computational strategies to improve the computational performance of high fidelity simulation software for modeling the progressive collapse behavior of blast damaged buildings. Its goal is to reduce the time required to compute and visualize high fideli ...

We propose a new active optical method to measure time-domain waveform of THz pulse in the vicinity of the target in an omni-directional manner. This method utilizes the THz radiation-enhanced-emission-of-fluorescence from laser-induced air plasma to detect the THz field, which enables the standoff sensing for low volatility chemicals using THz spectroscopy. We have demonstrated its capability of ...

A GREAT DEAL OF EFFORT HAS BEEN SPENT IN RECENT YEARS TO DEVELOP STANDARDIZED METHODOLOGIES FOR ACCEPTING AND VERIFYING EMP HARDENED MILITARY FACILITIES. THE FIRST OF THESE STANDARDIZATION EFFORTS TO BE PUT INTO EFFECT APPLIES TO FIXED SITE, CRITICAL, TIME URGENT C4I FACILITIES. THE REQUIREMENTS EXISTS FOR AN ADVANCED INSTRUMENTATION APPROACH THAT CAN OVERCOME THE DIFFICULT ACQUISITION ENVIRONMENT ...

ONE COMMON NUCLEAR WEAPONS EFFECTS CIMULATION TECHNIQUE SIMULATES THE EMP RESPONSE OF LONG CABLES USING DIRECT CURRENT INJECTION. DIRECT CURRENT INJECTION TYPICALLY INVOLVES THE CONNECTION OF HIGH VOLTAGE PULSE SOURCES TO THE CABLES THAT ARE ATTACHED TO A MILITARY SYSTEM. A RECENTLY DEVELOPED MILITARY STANDARD SPECIFIES THAT DIRECT CURRENT INJECTION TESTING WILL BE USED IN CONJUNCTION WITH SEVERAL ...
