ANALYTICAL AND TEST PROGRAM TO DETERMINE THE FEASIBILITY OF USING COMPOSITE MATERIALS TO REDUCE WEIGHT AND ENHANCE THE VIBRATION AND NOISE DAMPING CHARACTERISTICS OF NAVY GEARCASES WHILE MAINTAINING STRENGTH AND STIFFNESS REQUIRED TO SUPPORT TORQUE, BEARING AND HIGH IMPACT SHOCK LOADS. PHASE I WILL KEY ON IDENTIFYING THE BEST POLYMER AND METAL MATRIX MATERIALS FROM TRADE-OFF STUDIES OF MANY AVAILA ...

METHODS OF INTEGRATING ANALYTICAL AND EXPERIMENTAL TECHNIQUES TO PREDICT ELECTRONIC DEVICE RESPONSE TO VIBRATION AND SHOCK LOADINGS ARE PROPOSED. UNIQUE NONINTRUSIVE EXPERIMENTAL TECHNIQUES, COUPLED WITH ADVANCED DIGITAL SIGNAL PROCESSING ALGORITHMS, WILL BE USED TO VERIFY FINITE ELEMENT MODEL INPUT DATA, MODELING ASSUMPTIONS, BOUNDARY CONDITIONS, AND TO DETERMINE MATERIAL PROPERTIES SUCH AS DAMPI ...

THE OBJECTIVE OF THE PROPOSED EFFORT IS TO DEVELOP ADVANCED CAPABILITIES FOR COMPUTER CODES IN PREDICTING THE DAMAGE INFLICTED ON NAVAL TARGETS BY UNDERWATER WARHEADS. THE PROPOSED RESEARCH EFFORT WILL TAKE SOME HIGHLY REGARDED, WELL DOCUMENTED, AND VALIDATED GENERAL PURPOSE CODES AND ADD CAPABILITIES TAILORED TO THE UNDERWATER WARHEAD DYNAMICS PROBLEM AND COMBINE ALL REQUIRED CAPABILITIES INTO ON ...

THIS STUDY WILL BE CONCERNED WITH THE DEVELOPMENT OF A PROTOTYPE EXPERT SYSTEM WHICH WILL ACCOMPLISH TWO MAJOR FUNCTIONS WHEN IT IS COMPLETED. THE FIRST FUNCTION WILL CONSIDER TOP LEVEL SHIP, MISSION AND OPERATIONAL REQUIREMENT TO PRODUCE A LIST OF HULL, MECHANICAL AND ELECTRICAL (HM&E) SYSTEMS AND COMBAT SYSTEMS WHICH COULD BE USED IN THE DESIGN TO MEET THE REQUIREMENTS. WHERE APPROPRIATE, THE FI ...

THE OBJECTIVE OF OUR PROJECT IS TO DEVELOP NEW MEANS OF PRODUCING SHORT LIVED RADIOISOTOPES FOR POSITRON EMISSION TOMOGRAPHY (PET). THIS MEDICAL DIAGNOSTIC TECHNIQUE IS CAPABLE OF DISCERNING AND IMAGING MEDICALLY INTERESTING PHENOMENA, SUCH AS THE ACTIVITY OF VARIOUS PARTS OF THE BRAIN, OXYGEN FLOW IN THE BODY, AND OTHER QUANTITIES WHICH ARE IMPOSSIBLE TO DETERMINE BY ANY OTHER DIAGNOSTIC TECHNIQU ...

THIS PROPOSAL INVOLVES THE DEVELOPMENT OF TECHNIQUES FOR AUTOMATED PROCESSING OF SNYTHETIC APERTURE RADAR (SAR) IMAGERY. SPECIFICALLY, THIS TASK INVOLVES FINDING ALTERNATING CURRENT (AC) POWER LINES AND RELATED STRUCTURES FROM HIGH-RESOLUTION AIRBORNE SAR (ASAR) IMAGES. WE WILL IDENTIFY AREAS FOR IMPROVEMENT AND DEVELOP NEW TECHNIQUES AS NECESSARY TO STRENGTHEN WEAK AREAS. WE WILL ESTABLISH A METH ...

THIS PROPOSAL IS A PLAN FOR A PROOF OF CONCEPT DEMONSTRATION OF AN ARTIFICIAL INTELLIGENCE-BASED DECISION AID TO INTEGRATE PLANNING AND ANALYSIS OF AIR DEFENSE NETWORKS ON A SINGLE WORKSTATION. PROCEDURES FOR PLANNING AND ANALYZING AN AIR DEFENSE NETWORK ARE TIME AND LABOR INTENSIVE. THESE PROCEDURES CONSTITUTE ONE OF THE MOST DIFFICULT ASPECTS OF OPERATIONAL PLANNING BECAUSE OF TRANSITORY AIRSPAC ...

A SERIES OF WELL CHARACTERIZED IM6/3501-6 COMPOSITE PLATES WILL BE EXPOSED TO CONTROLLED, WILL INSTRUMENTED JP4 POOL FIRES OF VARYING DURATION. FIRE EXPOSED PLATES WILL BE CHARACTERIZED USING PULSE-ECHO ULTRASONIC, MICROSCOPY, DSC, TAG AND MECHANICAL TESTING IN FLEXURE AND SHORT BEAM SHEAR. TEMPERATURE AND HEAT FLUX DATA COMBINED WITH COMPOSITE CHARACTERIZATION RESULTS WILL BE USED TO DETERMINE OP ...

A FAMILY OF REACTIVE COUPLING AGENTS BASED UPON AN EXOTHERMIC DECOMPOSITION IS BEING DEVELOPED. THE REACTION MAY BE INITIATED THERMALLY OR WITH ACTINIC LIGHT. INITIATION MAY BE VARIED OVER A WIDE RANGE OF TEMPERATURES OR WAVELENGTHS, WHICH ALLOWS THE BONDING REACTION TO BE TAILORED TO THE ADHESIVE CURE PROCESS. EARLY STUDIES HAVE SHOWN THE FEASIBILITY OF USING THIS CHEMISTRY TO BOND TO METALS, CER ...

DEVELOPMENT OF REACTIVE PRIMER/MODIFIED PHENOLIC ADHESIVE SYSTEM IS PROPOSED FOR BONDING RADOME MATERIALS. INITIAL STUDIES HAVE SHOWN THAT THE REACTIVE PRIMER CHEMISTRY WILL FORM CHEMICAL BONDS WITH METALS, CERAMICS AND POLYMERS. A TWO-STAGE PRIMER IS PROPOSED THAT CAN BE BONDED TO A RADOME SUBSTRATE AND AN ADHESIVE IN TWO SEPARATE OPERATIONS, EITHER BY TEMPERATURE, ACTINIC LIGHT OR A COMBINATION ...
