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 ...

The opportunity exists to apply evolving technology for nonlinear adaptive control to autopilot design for precision guided munitions. The approach employs artificial neural networks to represent errors made in inverting the nonlinearities in a feedback inverting controller. Using an on-line method for weight adaptation results in a highly effective local approximator to the inversion error. Re ...

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 ...

EPIC Technologies proposes to develop a flexible high density multichip assembly technology capable of being bent and twisted to conform to the available space in a constrained military of commercial electronic system. EPIC will adapt its basic chips first multichip assembly technology to meet the requirements of a conformable assembly. EPIC's basic chip first technology has been previously deve ...

Hall thrusters typically operate at 50% efficiency, 1600 sec specific impulse and have a proven track record on Russion satellites. Despite this impressive performance there are several areas in which Hall thruster improvements are possible. The propsed effort will focus on two such areas (1) thrust density (thrust per unit frontal area of the engine) which at present decreases with increasing t ...

An innovative electro-optical vibration sensor concept is proposed for test and evaluation which will provide early detection and warning of aircraft structural damage. Patented technology will allow a compact, lightweight, and eye-safe laser velocimeter system to be constructed for vibration measurement. Phase I will demonstrate on representative aircraft type structure the ability of the laser ...
