PRESENT INFRARED DECOYS FOR PROTECTION OF NAVY SHIPS ARE RELIABLE, HIGH INTENSITY COMBUSTION SOURCES. HOWEVER, THEIR EMISSION SPECTRA HAVE CHARACTERISTICS WHICH ALLOW THEM TO BE DISTINGUISHED FROM THE SHIPS THEY ARE INTENDED TO PROTECT. IT IS DESIRABLE TO DEVELOP MODIFIED FUELS WHOSE COMBUSTION WOULD PRODUCE INFRARED SIGNATURES WITH THE APPROPRIATE SPECTRAL PROPERTIES. THIS GOAL REQUIRES A DETAILE ...

ANALYTIC POWER PROPOSES A SYSTEM ANALYSIS OF THREE POTENTIAL NAVAL AUXILIARY POWER PLANTS USING FUEL CELL TECHNOLOGY. A SYSTEMS ANALYSIS OF THIS APPLICATION IS MANDATORY BECAUSE, MORE OFTEN THAN NOT, THE FUEL CELL IS NOT THE LIMITING TECHNOLOGY. IN MANY CASES, THE FUEL PROCESSOR CAN BE MUCH LARGER THAN THE FUEL TAN AND THE POWER CONDITIONER MAY BE LARGER THAN THE FUEL CELL. CONVENTIONAL COMMERCIAL ...

WE WILL FOCUS ON THE DESIGN, PREPARATION, AND CHARACTERIZATION OF A SERIES OF ORGANIC POLYMERS WHICH WILL HAVE CONDUCTING CAPABILITIES COMPARABLE TO THOSE OF POLYACETYLENE, AN EXTREMELY CONDUCTIVE, YET UNSTABLE, ORGANIC POLYMER. THESE POLYMERS ARE TO HAVE INHERENT STRUCTURAL PROPERTIES OF ALIGNMENT AND STABILITY MODELLED AFTER NATURALLY OCCURING POLYMERS SUCH AS PROTEINS. UTILIZING INTUITIVE DESIG ...

THIS PHASE I PROJECT WILL BE DIRECTED TO INVESTIGATING A MU TIPHASIC CONTROLLED RELEASE SYSTEM FOR CATTLE REPRODUCTION MANAGEMENT. TWO SPECIFIC BIOLOGICAL MEDIATORS WILL BE EX- PLORED FOR APPLICATION AS IMPLANTABLE BIODEGRADABLE DELIVERYSYSTEMS. ONE WILL BE BOVINE FOLLICLE STIMULATING HARMONE (FSH) FOR INDUCING SUPEROVULATION IN COWS; THE SECOND WILL BE HEPATITIS B SURFACE ANTIGEN FUSED TO LHRH AS ...

A NONMETALLIC MATERIAL IS PROPOSED THAT CAN BE USED TO MANUFACTURE COATINGS OR COMPLETE SECTIONS OF HEAT EXCHANGERS WHICH ARE SUBMERGED IN SALTWATER FOR LONG PERIODS OF TIME. THE PROPOSED MATERIAL SHOULD BE RESISTANT TO THE SEAWATER EXPOSURE AND AT THE SAME TIME HAVE A THERMAL CONDUCTIVITY EXCEEDING 30 W/M-OC.

A RESEARCH AND DEVELOPMENT PROGRAM AIMED AT DEVELOPING A LI/SO(2)CL(2) CELL HAVING IMPROVED PERFORMANCE CHARACTERISTICS IS PROPOSED. THIS CELL, WHEN FULL DEVELOPED, IS EXPECTED TO HAVE A SIGNIFICANTLY HIGHER VOLUMETRIC ENERGY DENSITY THAN THE LI/SOCL(2) CELL. IMPROVEMENTS IN THE PERFORMANCE OF THE LI/SO(2)CL(2) CELL WILL BE ACHIEVED VIA THE FOLLOWING MODIFICATIONS: I. USE OF MIXED ELECTROLYTES, BA ...

MUCH WORK HAS BEEN DONE OF LATE IN OPTICAL TARGET TRACKING. THE BULK OF IT HAS INVOLVED CENTROID TRACKING, ROSETTE SCANNING, EDGE TRACKING, AND "INTELLIGENT TRACKING ALGORITHMS" SUCH AS BAYESIAN ALGORITHMS AND OTHER STATISTICAL METHODS. ALL OF THESE METHODS SUFFER FROM FLAWS THAT MAKE THE RESULTANT TRACKING SYSTEMS VULNERABLE TO SIMPLE COUNTERMEASURES. THE SIMPLEST, AND MOST EFFECTIVE COUNTERMEASU ...

GLASS FIBER-REINFORCED THERMOPLASTIC RESIN COMPOSITES CURRENTLY SHOW UNSATISFACTORY PERFORMANCE AS A RESULT OF INADEQUATE ADHESION AT THE FIBER/RESIN INTERFACE. INTERFACE MODIFICATION BY APPLICATION OF HIGH TEMPERATURE POLYIMIDE RESIN COATINGS TO GLASS FIBERS WILL GREATLY IMPROVE GLASS FIBER/THERMOPLASTIC RESIN INTERACTION. THIN, CONTINUOUS, POLYIMIDE COATINGS WILL BOND TENACIOUSLY TO GLASS FIBER ...

THE PERFORMANCE OF ANNULAR AND TOROIDAL SPLIT TRANSFORMERS OPERATING IN SEAWATER WILL BE COMPARED BY MEANS OF WATER-TANK EXPERIMENTS AND BY FLUX MAPPING WITH A COMPUTER. AN EQUATION WILL BE DEVELOPED FOR THE PREFERRED CONSTRUCTION WHICH WILL DESCRIBE THE COUPLING COEFFICIENT AND TRANSMISSION LOSSES AS A FUNCTION OF SEPARATION, SEA WATER CONDUCTIVITY, AND "DISORIENTATION."

PRESENTLY HIGH-POWER RADIO-FREQUENCY SWITCH DEVICES ARE CONSTRUCTED USING PACKAGED PIN DIODES. DUE TO THE HIGH THERMAL RESISTIVITY OF THESE DIODES, SWITCHING AT HIGH CW POWER LEVELS IS DIFFICULT. FURTHERMORE THE DRIVER CIRCUIT REQUIREMENTS FOR THE CONTROL OF THESE DEVICES ARE HIGH, RESULTING IN REDUCED SWITCHING SPEED AND BANDWIDTH, AS WELL AS INCREASED VOLUME, WEIGHT, AND COST. IN THIS PROPOSAL A ...
