Nanophase metal particles are becoming increasingly important in areas such as powder metallurgy, catalysis and energetic materials. One of the more important nanophase metals is aluminum . Although several promising routes for the production of this material exist, not one of these synthesis techniques have successfully addressed the issue of the oxidation of these same nanoparticles, which lea ...

CR1 has pioneered a process that allows, for the first time, the synthesis of a new generation of optical fibers made of oxide glasses of compositions other than silica, such as Y203-A1203. Stanford University has expertise and instrumentation to characterize fiber laser materials and evaluate device performance. The proposed research combines these capabilities to demonstrate feasibility of new ...

The use of synthetic data for the generation of target signature templates is a vital element of current and future automatic target recognition systems. [1] [2] Although current synthetic signatures closely match their measured counterparts, they suffer from two shortcomings: 1) susceptibility to model error and 2) poor representation of signature variance. The current model validation relie ...

With the increasing demand for higher component density and higher source frequencies in electronic circuits, the requirements for signal integrity and electro-magnetic compatibility have become paramount. Although some solutions exist for simpler packaging and signal integrity problems, the more challenging issues are the design, computational analysis and testing of piece-parts and systems. Re ...

The fabrication of large format, long wavelength (LWIR) mercury cadmium telluride based focal plane arrays (FPAs) is highly desirable for Air Force applications such as satellite power and array cooling reduction along with higher resolution. However, the development of large FPAs has been seriously impeded by the limited size of commercially available bulk Cd{sub 1-x}Zn{sub x}Te substrates. In ...

Large planar arrays which consist of several hundred to several thousand antennas provide narrow, high gain pencil beams. Electronic beam steering for terminal guidance radar can be achiev ed using frequency scanning, beam switching, time delay or phase delay. Electronics steering allows beam manipulations in tens of nanoseconds using compact, mechanically rigid structures. Due to the increase in ...

The goal of the project is to produce an innovative information software architecture for intelligent, dynamic data mining; one providing direct support for intelligent agents and scalable to very large data/knowledge bases. The objectives are to develop a new technology, deductive data mining, and use it to harness necessary extensions of inductive data mining technology needed to address video, ...

The US Air Force plans to develop and demonstrate an aero-propulsion engine for hypersonic flight to Mach 8. This program focuses on use of hydrocarbon fuels and expendable engine designs for long-range cruise missile applications. A critical element for realization to the Air Force's hypersonic vehile mission is advancement in supersonic combustion ramjet engine technology. Development of conc ...

As pulsed power devices mature a requirement emerges for the efficient coupling of the power source of remote locations. For certain applications this coupling can take the form of existing high power switch/conditioning technology coupled with a suitable transmission line. For mobile, remote or harsh environments standard connection techniques are too bulky and require too much set-up time to b ...
