THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

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 ...

Aerosols represent one of the more efficient methods to distribute biological and chemical agents throughout the atmosphere. Small aerosol droplets can be readily inhaled and easily penetrate deep into the lungs where they lodge in bronchial alveoli. Within the alveoli, chemical and biological agents can breach epithelial and endothelial cell layers and enter the bloodstream, where they cause da ...

Oscilla Power, Inc. (OPI) is developing a utility-scale wave energy harvester that is enabled by low cost and readily-available magnetostrictive alloys. T his device, which utilizes no moving parts, has the potential to deliver predictable quantities of electric power to coastal utilities, industrial users, and remote facilities at costs competitive with coal or gas. The Phase I project demonstra ...

AN "INHALATION SCREENING DOSE COLLAR-STANCHION MONITOR" WITHEMBEDDED MINIATURE THIN-WALL GEIGER-MUELLER RADIATION DETECTORS EVALUATES THE THYROID GLAND FOR NANOCURIE ACTIVITYINVENTORY. THE PRIMARY TECHNICAL OBJECTIVE IS TO ESTABLISH THAT THE "COLLAR-STANCHION MONITOR" WILL BE CAPABLE OF DETECTING WITHIN 15 SECONDS AND WITH 2 SIGMA CONFIDENCE AN ACTIVITY INVENTORY OF 0.7 NANOCURIES OF I-131 DOSE EQ ...

Currently, the accepted standard experimental model for measuring protective efficacy against botulism is the Mouse Lethality Neutralization (MLN) assay. Botulism poisoning is a life threatening condition that is not only a public health concern, but could also be a potential biological weapon. With seven serotypes of botulinum neurotoxins, there is need for an alternative to the MLN assay due t ...

We propose a metamaterial-enhanced microbolometer with strong absorption over a narrow band that is dynamically tunable over the 8-10 micron band. A single-layer photonic metamaterial consisting of a thin metal film perforated with a 2-D array of dielectric apertures will be deposited on an amorphous-Silicon layer acting as an absorber and bolometer. The metamaterial, in conjunction with planar di ...

Identification of organophosphates (OPs) based nerve agents, is vital to the protection of U.S. armed forces personnel. Existing detection methods use bulky and expensive laboratory equipment, negating their battlefield use. Colorimetric indicators such as the currently deployed M8 and M9 detection papers are the fastest, cheapest, and easiest type of detector to use; however, these cannot detect ...

Biological weapons are among the most serious threats facing the United States defense forces, today. Currently available bioaerosol sampling systems and cassettes require both sample preparation and a well equipped laboratory for analysis. Other detection methods rely on fragile bio-molecules for recognition of the target analyte. These systems are not suitable for onsite analysis. Infrared spec ...
