This proposal investigates the feasibility of using a systems analytic approach to model the critical processes supporting proliferation of weapons of mass destruction. It uses as a framework for synthesis a previously developed systems analysis model of biological weapons proliferation. The proposed approach consists of four tasks to: 1) extend the BW analytical process to encompass all WMD, 2) d ...

RECENT WORK IN VOLUME HOLOGRAPHY HAS LED TO THE DISCOVERY OF THE ORTHOGONAL DATA STORAGE TECHNIQUE. THIS METHOD OF HOLOGRAPHIC DATA RECORDING REDUCES THE CROSSTALK BETWEEN CHANNELS BY STORING MANY WAVELENGTH MULTIPLEXED IMAGES IN A PARTICULARLY EFFECTIVE USE OF K-SPACE. FURTHER REDUCTION IN CROSSTALK IS OBSERVED IN HOLOGRAMS STORED IN CERTAIN PHOTOREFRACTIVE CRYSTALS USING THE COUNTER-PROPAGATING ...

Jet engine test cells are faced with meeting regulations related to NOx emissions and opacity. Based upon reported research results, it appears that the Pulse Induced Plasma Chemical Process (PPCP) could be effectively applied to jet engine test cells for the control of NOx. The process provides high efficiency NOx removal at relatively low temperature without the need for NH3 injection. PPCP can ...

The development of a simple, reliable, and easily operated system to detect and measure airborne lead (Pb) to trace levels is the subject of the Phase I effort. Lead is toxic to humans at very low levels and is ingested easily by breathing air in which elemental Pb or compounds of this element are dispersed. In firing ranges there is an opportunity for shooters and range personnel to be exposed to ...

ADAPTIVE DIGITAL ARRAY PROCESSING IN AIRBORNE RADARS CAN PROVIDE A MAJOR IMPROVEMENT IN TARGET DETECTABILITY BY ADAPTIVELY SUPPRESSING CLUTTER AND JAMMING. THE EFFECTIVENESS OF THIS SPACETIME ADAPTIVE PROCESSING HAS BEEN DEMONSTRATED BY DETAILED SIMULATION AT ASI. RECENTLY, ARRAY RADAR FLIGHT TEST DATA WAS USED TO VERIFY THE PERFORMANCE OF ADAPTIVE RADAR. THE PROPOSED STUDY WILL EXTEND THE SIMULAT ...

PARAMETRIC X-RADIATION (PXR) IS PROPOSED AS AN INTENSE, TUNABLE, MONOCHROMATIC HARD-X-RAY SOURCE FOR THE DETECTION OF EXPLOSIVES. THIS RADIATION IS HIGHLY COLLIMATED, HAS A BANDWIDTH OF 0.1, AND AN INTENSITY EQUAL TO THAT OF SYNCHROTRON RADIATION ON A PER ELECTRON BASIS. PXR GENERATION IS ACHIEVED BY PLACING CRYSTALS INTO THE PATH OF ELECTRON BEAMS WITH ENERGY OF 6 MEV OR GREATER. THE VIRTUAL PHOT ...

The need for a graphical computer based functional emulation of a systems behavior has been identified by several requirements, including this announcement. The need exists for multiple stations which interact with each other as the actual real world system behaves. This project will provide a prototype vehicle to address this need. The prototype will demonstrate the capability and advantages of s ...

The applicant firm proposes to use their unique and patented powder metallurgy technology to produce FACT parts with increased reliability and reduced weight, and at lower cost than other methods. It will use new and innovatie power metallurgy equipment and methods that can be automated to give fast and efficient consolidation of high strength alloy powers to final product forms. It will also prov ...
