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 ...

N/A

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 ...

The primary objective of this proposed work is to develop a method of producing integrally stiffened, complex shaped monolithic structural components in high strength aluminum alloys at a lower cost and lighter weight than equivalent conventional built-up assemblies. In Phase I the feasibility of attaining this objective will be demonstrated by conducting a series of subscale experiments based upo ...

Solid Free Forming of monolith and uniform discrete reinforced materials has been demonstrated by fused deposition of heavily loaded slurries. In this program we will extend the fused deposition process to functional gradient material. The composition of material deposited will be controlled by the flow rates of two individual materials that are mixed in a low dead volume head. Thus, it will be po ...

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 ...
