KaZaK Composites and Stanford University propose to design, develop and demonstrate a prototype bending-twisting-coupled composite rudder for the DDG 51. The Phase I design and process development effort will include classical laminated plate theory,finite element analysis and VARTM mold flow analysis. Test structures will be fabricated by two different methods during Phase I. First, an approximat ...

Silicon has long been the semiconductor of choice for high-voltage power electronic applications. Recently, SiC has attracted attention because SiC is projected to have better performance than silicon. [1] SiC power switching devices have yet to becommercialized, largely due to SiC crystal defects, most notably the device-killing micropipe defect, which does not permit high total current parts t ...

The proposed Phase I will explore the application of composites of polymer and ferromagnetic shape memory alloys (FSMAs) to passive structural vibration damping. The large hysteresis present in the stress-strain behavior of NiMnGa, a ferromagnetic shapememory alloy (FSMA), and other shape memory alloys (SMAs) suggests that both FSMAs and SMAs have the potential to dissipate mechanical energy more ...

Polymer electrolyte membrane (PEM) fuel cells are candidates to fill the Army's need for high-energy lightweight power sources. Methanol is a more convenient fuel source than gaseous hydrogen, but requires advanced membrane materials and alternativeprocessing. SRL with partners Tulane University and Northeastern University has demonstrated Electron-Beam-crosslinked polyphosphazene membranes with ...

A random access, solid-state, optical cross-switch capable of 770 channel discrimination in the telecommunications C-band is designed and proven as an alternative to current thin-film WDM devices and as a mechanically robust alternative tomicroelectromechanical (MEMS) WDM devices. The device may be used in multiplexing (mux), demultiplexing (demux), or complete cross-switch configurations, and is ...

The sheer magnitude of information available online via the Internet has overwhelmed the ability of existing search tools to produce useful query responses. Current web-search techniques typically fail to correlate relevant documents that areidentified in different ways, such as synonyms and acronyms. The challenge is to find an approach that can obtain highly accurate matches even ...

The use of active flow control can reduce or eliminate the number of aerodynamic control surfaces in aircraft. Elimination of control surfaces results in a reduction of weight and drag, as well as radar observability. Recent advances in MicroElectromechanical Systems (MEMS) technology have rendered it a feasible alternative for unsteady flow sensing and control. This project will be performed join ...

This proposal encompasses a facile method for generating transgenic chickens. Traditionally, the approach to accomplish this has been to target the avian egg or embryo for gene insertion using either viral or 'standard' plasmids as vectors. In contrast,our proposed method introduces two new features, i.e. (1) novel transposon DNA vectors and (2) injection of DNA into the testes of immature males. ...

Triton Systems, Inc. and Clemson University propose to develop a flexible polymeric photovoltaic assembly using a highly efficient innovative photovoltaic polymer coupled with flexible polymeric support and protective layers that can withstand the spaceenvironment. The Phase I program will verify recent data from Clemson showing that a new polymer combination has the capability to meet power gene ...
