THE TREND IN ALL MATERIALS IS TOWARD THE CONTROL OF MICROSTRUCTURE. IN CERAMICS AND CERMETS THE EMPHASIS IS ON THE REDUCTION OF CRYSTALLITE SIZE AND THEREBY ON IMPROVING PHYSICAL PROPERTIES. POWDERS SHOULD BE EQUIZAXED AND LIMITED TO SUBMICRON RANGE, WITHIN A NARROW AND SPECIFIC SIZE DISTRIBUTION. EVEN MORE IMPORTANTLY LARGE QUANTITIES OF POWDERS MUST BE AVAILABLE AT REASONABLE COST. AS PRESENTLY ...

THE ABILITY TO FABRICATE CERAMIC ARMOR ECONOMICALLY IS DEPENDENT UPON SEVERAL FACTORS INCLUDING POWDER COST, FABRICATION TECHNIQUE, AND FINAL MACHINE COST. CANDIDATE CERAMIC SUCH AS TIB (2), AND B (4)C DO NOT SINTER TO FULL DENSITY. THEREFORE, NEAR-NET SHAPE FORMATION IS DIFFICULT AND EXPENSIVE, ESPECIALLY WHERE COMPLEX GEOMETRIES ARE INVOLVED. ART PROPOSES TO UTILIZE NEW POWDER SYNTHESIS TECHNOLO ...

THE PURPOSE OF THIS DEVELOPMENT PROPOSAL IS TO DEMONSTRATE HIGH SPEED RANGING AND CLASSIFICATION OF OBJECTS WITH A VERSION OF A&F'S PROPRIETARY 3D VISION SYSTEM. THIS SYSTEM HAS ALREADY DEMONSTRATED TARGET CLASSIFICATION AND RANGING IN REALISTIC ENVIRONMENTS IN WORK SUPPORTED BY NSWC. THE EMPHASIS OF THIS PROJECT IS TO INCREASE THE SPEED OF THE SYSTEM FROM IT'S PRESENT LEVEL.

GEOPHEX, LTD. PROPOSES TO DEVELOP AN AIRBORNE ELECTROMAGNETIC (AEM) SYSTEM DEDICATED TO THE DETECTION OF SUBMARINES IN THE OCEAN (TOPIC NO. N87-22, THE DOD SBIR PROGRAM, 1987). THE AEM METHOD HAS RECENTLY EMERGED AS A VIABLE TECHNIQUE FOR AIRBORNE CHARTING OF WATER DEPTH (IN EXCESS OF PERHAPS 100 M), WATER CONDUCTIVITY (THUS, SALINITY AND TEMPERATURE VARIATIONS), AND BOTTOM SEDIMENT CONDUCTIVITY ( ...

N/A

THE ELECTRICAL CONDUCTIVITY OF GRAPHITE EPOXY COMPOSITE MATERIAL IS A FUNCTION OF THE RELATIVE ORIENTATION OF THE APPLIED FIELD AND THE FIBER DIRECTION FOR UNIDIRECTIONAL MATERIAL. PRIOR ATTEMPTS AT NONCONTACT, NONDESTRUCTIVE ELECTROMAGNETIC METHODS OF CONDUCTIVITY MEASUREMENT HAVE NOT BEEN FULLY SUCCESSFUL DUE TO LOW LEVELS OF SIGNAL OR IMPROPER ORIENTATION OF THE ELECTROMAGNETIC FIELDS. TWO PROP ...

OAS PROPOSES THE USE OF CONDUIT ENCLOSED SUPERCONDUCTING CABLE WITH INTERNAL LIQUID HELIUM COOLING FOR POWER TRANSMISSION IN THE OPEN OCEAN. NIOBIUM-TITANIUM, NIOBIUM-TIN, AND THE NEWER LANTHANUMCOPPER-BARIUM-OXYGEN COMPOUND WILL BE EVALUATED AS SUPERCONDUCTORS. A COPPER MATRIX CONTAINING NIOBIUM-TITANIUM STRANDS BRAIDED TO WIRES AND TWISTED TO CABLES IS A PREFERRED APPROACH AT THIS TIME. STAINLES ...

A DESIGN APPROACH USING HIGH SPEED MICROPROCESSORS AND RAPID-ACCESS MEMORY DEVICES IS SUGGESTED FOR A STAND-ALONE INTELLIGENT BUFFER THAT INSERTS DELAYS TO COMPENSATE FOR SENSOR POSITION ERRORS IN THE SENSOR DATA STREAM THAT FEEDS A CONVENTIONAL BEAMFORMER IN REAL-TIME. THE MOTOROLA 68020 AND INTEL 80386 32 BIT HIGH SPEED MICROPROCESSOR CHIPS HAVE SEVERAL ATTRACTIVE FEATURES FOR THIS APPLICATION W ...

THE TECHNICAL OBJECTIVE IS TO PROVIDE A MECHANIZED SYSTEM RATHER THAN A MANUAL OPERATION IN THE NON-MECHANIZED BUILDINGS AND OUTDOOR AREAS. AN ADDITIONAL OBJECTIVE IS TO REDUCE OR ELIMINATE THE PROBLEMS INHERENT TO A "PAPER DRIVEN" WAREHOUSE SYSTEM. A PAPERLESS, RADIO LINKED DATA TERMINAL, WOULD PROVIDE "ON-LINE" INFORMATION WHICH WOULD INCREASE CONTROL AND ELIMINATE THE ERRORS.
