Use of chromates as corrosion inhibi.tors in coatings, adhesives and sealants is a well established technology. However, toxicity and waste disposal problems have led to the urgent need for development of an environmentally benign substitute for chromium compounds in coatings and sealants, which is the subject of this SBIR. This pa'per discusses the state-of-the-art technical approaches to the sol ...

A key component in the Alkali Metal Thermal to Electric Converter (AMTEC) is the electrode that is generally sputter deposited on the beta"-alumina solid electrolyte (BASE). Electrode deposition, as it is now practiced however, is a random process that covers active sites on the BASE and places many electrode pore openings at inactive sites. This proposal describes a novel fabrication process for ...

We propose the exploration of single crystal GaN waveguides for the fabrication of optoelectronic integrated circuits. The feasibility of using GaN for short wavelength (up to 365 nm) OEIC's will be established in Phase I via the demonstration of a channel waveguide based phase shifter. The Al(sub x)GA(sub 1-x)N material system with its transparency from 365 nm to 12 microns, tunable refractive in ...

Safety-critical aerospace applications have become increasingly dependent on a software component. However, conventional approaches to increasing the software reliability of these systems have focused on purely programming aspects. While these methods can all lead to techniques which should minimize the number of flaws in the logic of programs, none claim to result in generation of code with zero ...

MUCH RECENT WORK HAS BEEN FOCUSED ON ELUCIDATING THE POTENTIAL BENEFITS OF USING FUZZY LOGIC AND ADAPTIVE NETWORK DECISION MAKING METHODS. ADAPTIVE METHODS, LIKE BACK-PROPAGATION TAUGHT NEURAL NETWORKS, CAN MAKE IT POSSIBLE TO BUILD COMPLEX DECISION MAKING SYSTEM WHICH AVOID THE "EXPERT SYSTEMS" PROBLEM OF MANUALLY ACQUIRED KNOWLEDGE "CAPTURE." INSTEAD, THESE ADAPTIVE METHODS CAPTURE KNOWLEDGE BY ...
