Efforts to apply active noise and vibration control commercially, while intensifying, continue to be hampered by the cost of the computers required to implement the active algorithms. Currently, the cost of wide-band control is prohibitive for lightly damped systems such as precision structures or highly reverberant acoustic spaces, even if the system has just one canceling actuator and one error ...

A progressive system development is proposed which uses Bayesian methodology for combined detect, track, localize, and classify. The core paradigm focuses on detection followed by various estimation schemes to extract information on contact type, track, and location from the detector. A rapid prototype development using the Generic Multipurpose Processor (GMP) will provide optimal detection ...

Integration of many different devices on a single silicon carbide (SiC) substrate is necessary to realize the full potential of high temperature or high power devices for markets ranging from industrial and consumer to military systems to transportation power and control. Integration requires that the entire device package, individual devices, contacts and interconnect materials, be ...

The III-V nitrides, (Al, In, Ga)N, are promising materials for high temperature, high power and high frequency devices due to the wide bandgaps, high electron saturation velocity and high electronic mobility transistor (HEMT) structures available in this alloy system. These devices would find wide-spread commercial use as power amplifiers in base station transmitters for personal communications ...

This proposal is directed at creating discontinuous unidirectional composite from continuous unidirectional prepreg. The process, Selectively-Discontinuous-Fiber (SDF), introduces micro-cuts in preimpregnated unidirectional materials at specified locations. This process will allow unidirectional composite prepreg to be used for the fabrication of complex-compound components that have be ...
