THE MATERIALS USED IN THIN-FILM PHOTOVOLTAIC CELLS AND MANY OTHER SEMICONDUCTOR DEVICES ARE FREQUENTLY GROWN USING CHEMICAL VAPOR DEPOSITION (CVD) OR OTHER VAPOR-BASED PROCESSES. MANY OF THE PROCESS GASES USED, FOR EXAMPLE, ARSINE, PHOSPHINE, AMMONIA, DIBORANE, AND SILANE, ARE HIGHLY REACTIVE. CONTAMINATION, CHEMICAL OR PARTICULATE, OF THESE REACTIVE GASES SERIOUSLY INTERFERES WITH DEVICE PERFORMA ...

THE OBJECTIVE OF THIS EFFORT IS TO ASSESS LIGHTWEIGHT STRUCTURAL COMPOSITE MATERIALS WITH GREATLY IMPROVED FLAMMABILITY, SMOKE GENERATION, AND TOXIC FUME GENERATION (FST) PROPERTIES FOR USE IN NAVY INTERNAL SUBMARINE APPLICATIONS. THE MATERIALS TO BE EVALUATED CONSIST OF GLASS REINFORCING FIBERS BLENDED IN A THERMOPLASTIC MATRIX WITH PRECISE FIBER/RESIN VOLUME FRACTION CONTROL. THE THERMOPLASTIC ( ...

THE RECENT DISCOVERY OF HIGH TEMPERATURE SUPERCONDUCTING MATERIALS HAS LED TO RENEWED INTEREST IN THE APPLICATION OF SUPERCONDUCTIVITY. THE NEW CERAMIC SUPERCONDUCTORS OFFER THE OPPORTUNITY OF USING THESE MATERIALS AS DETECTORS OF INFRARED RADIATION MORE CONVENIENTLY THAT THE OLDER, CLASSICAL SUPERCONDUCTORS. THE LARGER ENERGY GAP OF THESE NEW HIGH CRITICAL TEMPERATURE (T(C)) MATERIALS ALSO PROVID ...

IT HAS BEEN DETERMINED IN BENCH SCALE AND PILOT SCALE COAL LIQUEFACTION EXPERIMENTS THAT A PRETREATMENT AT MODERATE TEMPERATURES PRIOR TO LIQUEFACTION CAN SUBSTANTIALLY IMPROVELIQUEFACTION YIELDS AND QUALITY. HOWEVER, THERE IS LITTLE BASIC UNDERSTANDING OF THE PROCESSES THAT GIVE RISE TO THE OBSERVED PHENOMENA. THIS PROJECT SUGGESTS THE IDENTIFICATION AND OPTIMIZATION OF THE PRELIQUEFACTION CHEMIS ...

FOR PHASE I, AMSI PROPOSES TO IDENTIFY AND ESTABLISH THE TECHNICAL FEASIBILITY OF VARIOUS ADVANCED ACOUSTIC ARRAY CONCEPTS. THREE GENERIC APPROACHES ARE CURRENTLY IDENTIFIED: 1) OPTIMIZE THE SENSOR DESIGN (I.E., DIRECTIONAL SENSORS, ETC.), 2) OPTIMIZE HYDROPHONE/ GROUP/ARRAY GEOMETRY (I.E., MULTI-APERTURES, ETC.), AND 3) IMPLEMENT SIGNAL PROCESSING TECHNIQUES (I.E., VARIOUS ANALYTIC CONTINUATION T ...

THE NAVAL UNDERWATER SYSTEMS CENTER HAS A CLEAR NEED FOR DETECTING AND CLASSIFYING ACOUSTIC SIGNALS. THESE SIGNALS MAY REPRESENT SHIPPING TRAFFIC, NATO NAVAL ACTIVITIES,, BIOLOGICALLY GENERATED SIGNALS (SUCH AS PRODUCED BY WHALES AND OTHER MARINE LIFE), ENVIRONMENTALLY GENERATED SIGNALS (CRACKING OF GLACIERS, ETC.), OR HOSTILE MILITARY ACTIVITY. SOME OF THESE SIGNAL SOURCES CAN BE MODELED FAIRLY W ...

IT IS PROPOSED TO USE PHASE I TO ASSESS THE APPLICABILITY OF A NEW ULTRASONIC HEAD-TRACKER SYSTEM DEVELOPED FOR HELICOPTER USE BY AEG, A PROTOTYPE OF WHICH COULD BE MADE AVAILABLE TO W.W. GAERTNER RESEARCH, INC. FOR THIS TEST. IF THE ACCURACY OF THE ORIGINAL PROTOTYPE IS NOT ADEQUATE, SEVERAL DESIGN IMPROVEMENTS ARE SUGGESTED WHICH COULD BE IMPLEMENTED UNDER PHASE II.
