A program is proposed to examine and develop an innovative fabrication technique to produce the finest diameter ceramic piezoelectric "micro-rods." The production of large quantitities of uniform, straight piezoceramic micro-rods with diameters less than 75 um and at least three centimeters in length will be developed. Completion of this program will probe the versatility and limits of the method, ...

This Phase I effort will design a highly integrated communication system featuring; virtual connectivity over multiple communication media, demand multiplexing of multiple information sources, voice, video, image and data I/O, user pull access to information, encryption, data compression, ATM network interfacing, rmote access via a broadband LAN, a broad range of computing platforms and ocnfigurat ...

THE UNDERSTANDING OF MECHANISMS INVOLVED DURING MICROBIOLOGICALLY INDUCED CORROSION (MIC) OF EPOXY COATED, NYLON COATED, AND POLYURETHANE COATED METALS IN COOLING SYSTEMS IS OF THE UTMOST IMPORTANCE TO NAVAL OPERATIONS. OF PARTICULAR IMPORTANCE ARE THE ROLE OF MECHANISMS BY WHICH MARINE ALGAE AND PROTOZOA CONTRIBUTE TO THE BIOCORROSION PROCESS. THERE ARE CONCERNS THAT ELECTROCHEMICAL MONITORING ME ...

Vapor deposited diamond possesses excellent characteristics as a protective material for the infrared windows and radomes of high speed missiles. At high temperature, diamond is itself subject to rapid erosion when exposed to oxygen. In order to protect diamond against oxygen a thin layer of the diamond surface can be transformed into silicon carbide. Silicon carbide is hard, thermally stable and ...

A need exists for low cost-per-station density measurements to be made in conjunction with many moored and free-drifting oceanographic platforms. This need is particularly acute in situations where Acoustic Doppler Current Profilers (ADCP's) are used on a measurement string. The ADCP has the advantage of being able to remotely profile the velocity field up to several hundred meters away from the i ...

There is a need at U.S. Navy and other armed service facilities for improved vehicle barriers which can be deployed quickly. These barriers, or vehicle disabling devices, must reliably stop vehicle threats from entering secure zones. This Phase I project will de- fine explicit performance criteria for barriers in this applica- tion, characterize existing methods, and develop new barrier and disbab ...

WE PROPOSE TO DEVELOP A NEW CLASS OF INSULATION THAT MEETS THE PERFORMANCE OF THE CURRENTLY USED POLYPHOSPHAZENE FORAM INSULATION WHILE BEING MORE ECONOMICAL, AND PROVIDING IMPROVED FIRE PERFORMANCE. OUR TECHNICAL APPROACH COMBINES THREE ENABLING TECHNOLOGIES TO PRODUCE AN INNOVATIVE INSULATION THAT IS IDEAL FOR SUBMARINES, AS WELL AS A VARIETY OF OTHER SHIPBOARD AND INDUSTRIAL APPLICATIONS. THESE ...
