The objective of the proposed project is to develop innovative new analytical instrumentation and methodology capable of performing fully automated, non-destructive analysis of semiconductor sensor elements and arrays locate on three inch diameter wafers. The instrumentation would be capable of analyzing II-VI compounds and alloys, particularly HgCdTe. The methodology would employ state-of-the-a ...

The scattering behavior for a collection of thousands of linear dipoles at resonance has long been a subject of study for passive electronic countermeasures (ECM) against pertinent threat radar systems. Previously, the echo area of the radar cross section (RCS) of a chaff cloud has been calculated by multiplying the number of dipoles by the so-called "tumble average RCS" of a single dipole. Estima ...

BASED UPON EARLIER EXPERIMENTAL WORK, IT WAS DISCOVERED THAT ULTRASONIC RADIATION OF THE PROPER FREQUENCY WOULD PRECIPITATE SMOKE AND AEROSOLS WITHIN THE RADIATION PATTERN. THE PURPOSE OF THIS EFFORT IS TO EXPERIMENTALLY PROVE THE FEASIBILITY OF USING THE CONCEPT TO CLEAR SMOKE AND AEROSOLS FROM A BATTLEFIELD. TWO SPECIFIC APPLICATIONS WILL BE STUDIED, 1) TO CREATE A SMALL AREA OF CLEAR AIR TO TAR ...

The extensive use of heavy metals in prior industrial/military operations has resulted in numerous sites with soil/groundwater contamination. Phytoremediation research has shown that plants can successfully uptake heavy metals from contaminated sites. Recent research on phytoremediation of heavy metals has focused on vegetation such as Eastern Gamagrass (Tripsacum dactiloides) and Indian Mustard ...

This project will analyze and select promising materials and designs to be used in the plumes of tactical solid rocket motors for missile steering and control. The emphasis is on high-performance refractory materials and compatibility of material systems. The control fins experience severe thermal and severe particulate erosion environments. Missile controllability requires fins with minimal er ...

COMPOSITE MATERIALS ARE ATTRACTIVE FOR USE IN AIRCRAFT AND SPACECRAFT OWING TO PROPERTIES OF HIGH SPECIFIC STRENGTH. A PROBLEM CONFRONTING THE APPLICATION OF COMPOSITE MATERIALS FOR ROTORCRAFT IS THAT UNIMPROVED LANDING AREAS, AS WELL AS LOW ALTITUDE MISSIONS, RESULT IN SEVERE ABRASION OF THE COMPOSITES, PARTICULARLY ON COMPOSITE BLADES. OTHER SOURCES OF ABRASION ON BLADES, AS WELL AS AIRFRAME STR ...
