This proposal seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify explosive detonators. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape, and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by ...

Light scatter has been used to map and size particles on silicon wafers for many years, producing accurate maps of particle position and giving an indication of particle size, but do not reveal any information about particle composition. Today's technology is limited by noise, precluding detection of the smallest particles of interest. Present instruments are not adequate for the next generation ...

Development of efficient spray combustors requires a complete understanding of fundamental phenomena that influence and control the overall spray combustion process. Toward this end, detailed experimental characterization of spray flames is essential. This includes measurement of various fuel droplet parameters such as droplet size, velocity, number density, temperature, composition, and droplet ...

There is a global trend towards utilization of satellite communications for information services. Equivalent system temperature, Ts, is a significant parameter in quantifying the antenna system/link performance, because it represents the noise power spectral density in antenna system figures-of-merit, such as receiver gain/system temperature (G/T), and end-to-end Signal to Noise Ratio (SNR). Unf ...

The specific problem addressed by the proposed research is the development of a scanner for storage phosphor plates with significantly better positional and intensity accuracy than the current state of the art. The new scanner will be based on the use of a "scanning head" scanning approach which is more simple, accurate, and stable than the approaches previously used. This results in stable and ...

With the advent of widely available PC technology, crash safety information can be cost-effectively disseminated to millions of people in an engaging and educational way. With an enticing and informative PC application, data about damages, costs, injuries and death can be personalized and grasped by anyone, particularily young drivers developing new driving behaviors. ARCCA's proposed system wil ...

The Proposed Innovation is real-time hardware for image processing, image understanding and machine vision that will achieve significant performance increases over current systems by implementing a set of operations required to support a specific set of algorithms. These algorithms are intended to process and analyze multiple, parallel partial derivative images or "Jet bundles" which provide a fr ...

CURRENTLY COMMERCIAL SPACE-LAUNCH FREQUENCY REQUIREMENTS ARE MET IN THE 2200- TO 2300-MHZ BAND. NEW FREQUENCY ALLOCATIONS MAY LIMIT FREQUENCIES FOR COMMERCIAL SAFE AND RELIABLE COMMERCIAL SPACE-LAUNCH OPERATIONS TO THREE CHANNELS IN THE 2360- TO 2390-MHZ BAND. THIS RESEARCH WILL ASSESS WHETHER THIS ALLOCATION IS SUFFICIENT TO ENSURE CONTINUED SAFE AND RELIABLE COMMERCIAL SPACE-LAUNCH OPERATIONS. D ...
