AN EXPERT SYSTEM REQUIREMENTS AND DEVELOPMENT PROGRAM IS PROPOSED TO ACHIEVE AN EXPERT SYSTEM FOR JOINING COMPOSITE MATERIALS. THE NEED IS TO ASSIST DESIGN ENGINEERS TO ACCESS LARGE AMOUNTS OF JOINT DESIGN AND DATA THAT IS AVAILABLE. THE EXPERT SYSTEM WILL PROVIDE ALPHANUMERIC AND GRAPHICS INFORMATION TO THE DESIGNER TO ASSIST IN THE OPTIMUM SELECTION OF COMPOSITE MATERIALS JOINING TECHNIQUES. THE ...

EMISSION OF SULFUR OXIDES (SOX) AND NITROGEN OXIDES (NOX) IN FLUE GASES IS A MAJOR CAUSE OF AIR POLLUTION AND ACID RAIN. CURRENT TECHNOLOGIES FOR SOX REMOVAL ARE EXPENSIVE AND CUMBERSOME. SULFUR DIOXIDE IS CONVERTED TO SULFURIC ACID, WHICH IS VERY CORROSIVE AND DIFFICULT TO STORE AND TRANSPORT. REMOVAL OF NOX IS ACCOMPLISHED BY CATALYTIC CONVERSION USING PLATINUM CATALYSTS. PLATINUM CATALYSTS ARE ...

EACH PHASE OF THE DEVELOPMENT LIFE CYCLE IS IMPORTANT AND THE PRODUCTS OF EACH ARE ESSENTIAL FOR A SUCCESSFUL SYSTEM. HOWEVER, DEVELOPMENT TECHNIQUES AND TOOLS ARE PHASE-SPECIFIC AND DO NOT COMMUNICATE WITH ONE ANOTHER. WE BELIEVE THAT THIS IS THE CASE BECAUSE DEVELOPERS HAVE NOT YET DISCOVERED A UNIFYING CONCEPTUAL MODEL OF INFORMATION SYSTEM DEVELOPMENT CONSTRUCTS APPLICABLE TO THE WHOLE LIFE CY ...

FOR PHASE I, APPLIEDMEASUREMENT SYSTEMS, INC. (AMSI) PROPOSES TO IDENTIFY AND ESTABLISH THE TECHNICAL FEASIBILITY OF A SELF-CONTAINED HULL POTENTIAL MEASUREMENT SYSTEM FOR UNDERWAY SHIPS. THREE GENERIC APPROACHES ARE CURRENTLY IDENTIFIED: 1) MEASUREMENT SENSOR SELECTION, 2) ELECTRONIC/SOFTWARE DESIGN, AND 3) STRUCTURAL ARRANGEMENT DESIGN. MORE TECHNIQUES MAY RESULT FROM THE COMPREHENSIVE LITERATUR ...

COMPOSITE EXPLOSIVE MATERIALS LIKE PLASTIC BONDED EXPLOSIVES (PBX'S) ARE CONSIDERABLY LESS SENSITIVE TO HEAT, SHOCK AND IMPACT THAN CONVENTIONAL TNT-BASED EXPLOSIVES. THE NAVY USES THESE IN MANY LOW VOLUME MUNITIONS. THEIR INTRODUCTIONN INTO HIGH USE MUNITIONS WILL PROVIDE SUBSTANTIAL SHIP/PLATFORM SURVIVABILITY IMPROVEMENTS. THESE MATERIALS ARE COMPLEX AND COSTLY TO MIX AND LOAD USING EXISTING HI ...

REAGENTS AND REACTION PROCEDURES WILL BE DEVELOPED DURING PHASE I FOR THE COUPLING OF ANTIBODY MOLECULES TO THE ACTIVATED SURFACE OF MICROCHIP CAPACITANCE SENSORS. PROPRIETARY PHOTOAFFINITY REAGENTS WILL BE SYNTHESIZED AND COUPLED TO THE ELECTRODE SURFACE FOR SPECIFIC COVALENT BINDING OF MONOCLONAL ANTIBODY (USING ONE OF THE TWO ANTIBODY BINDING SITES). THIS WILL LEAVE THE REMAINING STABILIZED ANT ...

RECENT ADVANCES IN STATE-OF-THE-ART LASER TECHNOLOGY SHOULD PERMIT THE DEVELOPMENT OF DETECTING AND LOCALIZING TORPEDOS USING BLUE-GREEN XENON CHLORIDER LASERS, STEERED BY BRAGG CELLS TO DEFINE A PROTECTIVE ENVELOPE OR PERIMETER AROUND A MOVING SHIP. BRIMROSE PROPOSES TO EXAMINE CONVENTIONAL MIRROR STEERED SYSTEMS, AS WELL AS THE ACOUSTOOPTIC LASER BEAM STEERING METHOD TO COMPARE OPERATIONAL ADVAN ...

CERAMATEC HAS CONDUCTED EXPLORATORY RESEARCH AND DEVELOPMENT ON MONOLITHIC AND COMPOSITE MATERIALS IN THE ZRB2 AND TIB2 SYSTEMS AND HAS OBTAINED VERY ENCOURAGING RESULTS WITH SEVERAL PROPRIETARY COMPOSITIONS/CONSTRUCTIONS. THE AVERAGE STRENGTH OF A BASELINE TIB2 COMPOSITION WAS MEASURED AT 877 MPA (127.3 KSI). COMPOSITE STRUCTURESWITH DISCONTINUOUS REINFORCEMENT HAD STRENGTHS IN THE RANGE 400-600 ...

THE OVERALL OBJECTIVE OF THIS PROJECT IS TO DEMONSTRATE THE SUCCESSFUL FABRICATION AND DENSIFICATION OF CERAMIC MATRIX COMPOSITES FORMED BY INJECTION MOLDING. TO ACCOMPLISH THIS OBJECTIVE, A DESIGNED TEST MATRIX WILL BE DEVELOPED THAT WILL SYSTEMATICALLY INVESTIGATE THE KEY INJECTION MOLDING AND DEBINDING PARAMETERS SUCH AS BINDER COMPOSITION, SOLIDS RATIO, MOLDING CONDITIONS, DEBINDING CONDITIONS ...
