A portable fluorometric spectral analyzer for rapid field or shipboard diagnosis of Campylobacter enteritis and Shigella dysentery Is proposed for Phase I feasibility demonstration. All living cells are fluorescent and exhibit "fingerprint" spectral patterns that allow for their detection and Identification. The Campylobacter and Shigella bacteria have specific fluorescent patterns that may ...

Broadband signal processing is important for interpreting signals received from active sonar transmissions. The traditional approach to processing broadband signals in the sonar literature is to assume a harrowband condition that Justifies the use of narrowband signal processing. RTcently there has been renewed interest in avoiding the narrowband assumption and in actually using techniques th ...

For more than three decades, transportation planners have relied on survey data collected specifically for the development of travel forecasting models, which are expensive to collect and maintain on an ongoing basis. There is a plethora of data collected for other reasons that could potentially support transportation planning which is becoming more accessible through technological advances. Use ...

In this proposal, new fabrication techniques for high density 2D medical ultrasound arrays will be developed. These techniques will allow for the construction of 10 to 50 MHz arrays with very high element counts, complex 2D geometries, and much smaller structures than can be effectively fabricated today using traditional dicing saw techniques. The proposed fabrication method represents a signific ...

Extensive research (Ukraine) has shown that high strength continuous fibers of basalt can be produced. These fibers are inexpensive and have exceptionally high strength, stiffness and corrosion resistance. Basalt is a naturally occurring volcanic mineral, consisting a variety concentration of oxides. The product envisioned is a low-cost, corrosion resistant replacement for steel bar in reinforc ...

The proposed study will evaluate the effectiveness of combining polishing and doping to reduce twin nucleation sites and to prevent twin boundary movement in sapphire to improve its thermal shock resistance. Doped and undoped single-crystal sapphire will be grown by the Czochralski method. The crystal surfaces will be mechanically and chemically polished. Dopant diffusion into the surface l ...
