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 ...

The USAF Material Command (AFMC) and the Defense Logistics Agency (DLA), Defense Microelectronics Activity (DMA) has a critical need to support military planners in establishing a cost effective approach to selecting components and identifying system behavior during the design process, minimizing expensive testing and design failures. Current test facilties are expensive to run as well as time co ...

Future USAF vehicles (missiles/fighter aircrafts) will have to operate under high altitude flight conditions in order to reach global targets and/or to meet unforeseen threats to the security of USA. A new accurate engineering code is needed to determine quickly the aerothermal characteristics of the vehicle and optimizeits shape, trajectory, and/or performance. The maneuvering vehicle will have ...

THE GOAL OF THIS PROGRAM IS TO IDENTIFY SPECIFIC NEURAL NETWORK ARCHITECTURES AND ALGORITHMS WHICH ARE APPLICABLE TO COMMUNICATIONS PROBLEMS AND EVALUATE THOSE ARCHITECTURES AND ALGORITHMS VIA SIMULATION AND MODELING. WE DEFINE HEREIN A SYSTEM CONSISTING OF TWO DIFFERENT NEURAL NETWORK PARADIGMS WHICH ARE INTEGRATED TO PERFORM AUTOMATIC IDENTIICATION AND DEMODULATION OF DIGITAL COMMUNICATIONS SIGN ...

Station keeping operations of satellites are primarily planned and executed from the ground control centers. With future trends towards operating satellites as part of a larger constellation, both in geostationary orbit (collocation) and lower Earth orbits, the availability of autonomous station keeping will become more critical. This proposal envisions the design of one such innovative autonomo ...
