There is a great need for pure oxygen generators for chemical and biological defense. Crystals & Ceramic Technology, Inc., proposes to investigate electromechanical generators with thin (dense) ceria-based electrolytes. The thin ceria-based electrolytes will be deposited on palladium-conductive manganite electrodes supported on porous alumina tubes by organometallic chemical vapor deposition. F ...

Survival rates of human platelets cryopreserved using current methods are very low (10%). This is largely due to a lack of knowledge regarding the fundamental cryobiology of this cell type. Because of this limitation, most blood banks maintain platelets in non-frozen solutions. Using this approach, platelets can only be stored for about 5 days and then they are discarded. This situation greatl ...

We propose to develop automated video indexing and retrieval mechanisms based on comprehensive representations of video data, and efficient processing for automated in-dexing. Content-based video data retrieval has enormous potential in defense, industry and the government. However, a number of stubborn problems have impeded progress in developing fully automated video database systems. These p ...

Recently, PCKA personnel developed a modeling technique that will revolutionize power/drive system simulation. Therein, a detailed state model is automatically developed from a circuit description of the power/drive system component. This approach, which is referred to as an automated state model generator (ASMG), markedly reduces the engineering time needed to implement a detailed simulation t ...

The overall objectives of the proposed program are to develop non-invasive, wear resistant, light weight sensors and instrumentation for in-situ monitoring of temperature and vapor pressure for space and land based anti-friction rolling element bearings. This will be achieved by depositing thin films of appropriate materials on the raceways of rolling element bearings using RF-sputter coating and ...

This project will conduct experiments and perform analyses to determine the feasibility and methods for reducing or eliminating high cycle fatigue failures in gas turbine engine turbine blades and other components through the employment of air film damping techniques. Specifically, this project will investigate the efforts of air film damping on the dynamic behavior and modal damping of flat can ...

Cryogenic components are being proposed for a ground-transportable radar (GTR) systems. Incorporating low-loss components into power-electronic based systems is a concern from the standpoint of system stability due to the inherent low resistance of the cryogenic components which may tend to destabilize the system due to reduced damping. The purpose of the work proposed herein is first to investiga ...
