Knowledge based methods have the potential to offer high performance solutions to a wide variety of problems. However, the development of large scale knowledge bases (KBs) and their effective application to problems have so far proved to be more expensive and less feasible than other competing methods such as statistical methods or weak search techniques. There is an immediate and critical need to ...

DIAGNOSTx Technologies proposes to develop a PC-based instrument for the clinical evaluation of peripheral and central hearing deficits, which will allow audiometric, otoacoustic emissions, evoked-potentials and immittance testing. The integrated system will be capable of assessing hearing sensitivity for speech and pure tones, of evaluating the integrity outer hair cells and auditory central ner ...

The project goal is to produce an algorithm for synthesizing auditory distance which will be accurately perceived with little or no learning required. The algorithm could be added to an existing AF 30D audio system which uses headphones in a noise-reducing helmet. The approach is to combine very accurate recently developed atmospheric modeling with head-related transfer functions (HR ...

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 ...

Wind noise in outdoor measuemetn micropnones can mask an acoustic signal. Windscreens provide some wind noise reduction; however, those typically used for outdoor applications provide noise reductions of approximately 10-15 dB. Planning Systems Incorporated (PSI) proposes to design and test a Multiple Aperture Sensor System (MASS) consisting of a microphone, a processor, and data acquisitio and ...

As organizations move toward increased performance measurement and accountability, there is an increasing need to measure job performance at the individual worker level. Traditional assessment tools have been criticized as measuring test taking skills more than job performance skills. A number of approaches have been developed to address this weakness by measuring performance in practical proble ...

ION BEAMS WILL BE APPLIED IN SEVERAL ASPECTS OF PROCESSING ZNSE OPTICAL COMPONENTS. FIRST THE MATERIAL WILL BE MILLED, AND THEN IT WILL BE COATED USING ION ASSISTED DEPOSITION TECHNIQUES. REDUCED SCATTER FROM THE SUBSTRATE AND IMPROVE OPTICAL AND MECHANICAL PROPERTIES OF THE FILM ARE ANTICIPATED.

Project will develop an inexpensive vehicle identification system capable of identifying vehicles at speeds from 0 to 85 miles per hour using a conventional inductive loop or an overhead reader. System will have the following characteristics: 1) compatible with existing vehicle detector inductive loops already installed at many facilities minimizing implementation costs, 2) utilize low frequency ...

With the development of compact, rugged laser diodes that can be powered with bateries, it appears that medical procedures that utilize lasers can now be brought into the field environment. The goal of this effort is to develop a fieldable laser diode tissue soldering system for wound stabilization. In this technique, a laser is used to thermally cure a protein solution placed onto a wound. Thi ...
