The objective of this project is to extend the existing Message Translator and Validator (MTV) model's range of applicability for a variety of application areas and platforms. The MTV model is a scalable set of Ada code templates and generics that convert between external communication formats and application-specific data formats. In Phase I we will apply the Object-Connection-Update (OCU) model ...

During launching of regenerative liquid propellant guns, the projectiles and their components experience potentially damaging high pressure/high frequency oscillations. The purpose of this program is to develop the experimental and computational facilities to simulate these effects. The three major objectives to be accomplished in Phase I are: (1) To develop a method of inducing forced vibrations ...

We propose development of a 'smart' optical preprocessor that installs as an integral part of the light gathering optics of first- or second-generation forward looking infrared imaging systems (FLIRs). This optical preprocessor is based on an advanced-art imaging acousto-optic tunable filter (aka, A-O filter). These newly-configured A-O filters are programmable to seek out specific spectral featur ...

The theoretical maximum energy product of intermetallic compounds Nd2Fe14B and Pr2Fe14B is as high as 64 M Oe at room temperature. However, the actual energy product achieved in the laboratory is ~50 M Oe and the best commercial magnets exhibit only ~45 MG Oe. The inability to fabricate magnets with energy products close to 64 MG Oe is caused in part by 1) an imperfect grain alignment and 2) the p ...

THE REQUIREMENTS OF COMPLEX SAMPLE MONITORING PRESENT A GROWING NEED FOR A NEW GENERATION OF HIGHLY SPECIFIC ENZYME ELETRODES WITH MULTI-ANALYTE, MULTI-SIGNAL CAPABILITY. THIS PROJECT'S OBJECTIVE IS TO ESTABLISH THE FEASIBILITY OF NOVEL ELECTROCHEMICAL SENSORS BASED ON THE COMBINATION OF IMMOBILIZED ENZYMES AND COLLOIDAL GOLD TECHNOLOGIES. THE SPECIFIC GOAL TO BE PURSUED IN PHASE I IS TO DEMONST ...

At this time it is very difficult to distinguish viral infections from bacterial infections. Published results suggest that some subtypes of interferon-alpha (INF-a) are present in viral infections and are not detected in bacterial infections but no clinically useful assay for this potential marker for acute viral infections exits at this time. The government and the private sector has a strong ...

APA Optics will develop a monolithic UV seeker for use in flame sensing and passive or tactical threat warning systems. The key to the technical approach is the deposition of high optical/electrical quality Al(x)Ga(1-x)N over GaAs substrates and using it to fabricate back to back Schottky barrier detectors. Al(x)Ga(1-x)N is a compound III/V semiconductor system with a bandgap tunable from 220 to 3 ...

We propose a six month Phase I program to demonstrate the feasibility of growing A1N single crystals to serve as substrates for subsequent A1xGa1xN epitaxy. Our approach is to use a low pressure, high temperature (>>2000oC) furnace with a temperature gradient between the A1N charge and the deposition (seed) regions. Our approach is based on several innovations. These include the use of single prec ...
