SUCCESSFULLY APPLYING MODEL-BASED REASONING TO REAL WORLD VISION PROBLEMS (E.G. AUTOMATIC TARGET RECOGNITION ?ATR?) REQUIRES ACCURATE REPRESENTATION OF COMPLEX RELATIONSHIPS AMONG THINGS IN THE WORLD AND OBSERVABLE IMAGE FEATURES. EVIDENCE ACCRUAL TECHNIQUES MUST BE ABLE TO OPERATE OVER THESE RELATIONSHIPS WITH LITTLE LOSS IN INFORMATION. CURRENT TECHNIQUES SUCH AS BAYESIAN NETWORKS SHOW PROMISE, ...

HIGH-RESOLUTION COMPUTED TOMOGRAPHY SHOWS SIGNIFICANT PROMISE IN AIDING THE DEVELOPMENT OF ADVANCED COMPOSITE MATERIALS WHICH ARE IMPORTANT IN IMPROVING AIRCRAFT PERFORMANCE. NONDESTRUCTIVE IMAGING OF THE INTERNAL STRUCTURE OF THESE MATERIALS CAN HELP IN IMPROVING PROCESSING QUALITY, IN DEVELOPING PERFORMANCE MODELS, AND IN EVALUATING MANUFACTURED COMPONENTS. CURRENT IMAGING PERFORMANCE COULD BE S ...

THE OBJECTIVE OF THE PROPOSED WORK IS TO DEVELOP TECHNIQUES FOR DETECTING AND QUANTIFYING WEAK OR "KISSING" DEBONDS IN SOLID ROCKET MOTORS. THE PROPOSED TECHNIQUE IS BASED ON X-RAY COMPUTED TOMOGRAPHY.IT IS INNOVATIVE BECAUSE IT DOES NOT REQUIRE THAT ANY GAPS IN THE DEBOND AREA BE RESOLVED. INSTEAD, IT RELIES ON MEASUREMENTS OF THE PROPELLANT DILATATION NEAR THE BONDED INTERFACE TO SHOW WHETHER LO ...

AN INNOVATIVE APPROACH TO DESIGNING AN ADAPTIVE BBT MISSILE AUTOPILOT USING A TECHNIQUE KNOWN AS GSLQ IS THE BASIS OF THE FOLLOWING PROPOSAL, THE BENEFITS OF WHICH INCLUDE: (1) BEST TRADEOFFSBETWEEN PERFORMANCE AND ROBUSTNESS AMONG DIFFERENT DESIGN METHODOLOGIES; (2) THE ABILITY TO ACHIEVE LOOP TRANSFER FUNCTION RECOVERY (LTR) EXACTLY, AND NOT ASYMPTOTICALLY; (3) ADDITIONAL POLE PLACEMENT CAPABILI ...

AN INNOVATIVE LOW POWER DIGITAL COMMUNICATION (LPDC) SYSTEM IS PROPOSED WHICH WILL ENCODE RAW DATA FROM THE SELF POWEREDVEHICLE DETECTORS (SPVD) SENSORS AND SEND ENCODED DATA TO THE RECEIVED BASE STATION VIA THE LPDC DEVICES. THE PROPOSED ENCODING ALGORITHM WILL ALLOW THE LPDC TO OPERATE RELIABLY IN THE PRESENCE OF INTERFERENCE FROM OTHER COMMUNICATION USERS. PRELIMINARY ANALYSIS SHOWS THAT BY UTI ...

THE INNOVATIVE PROPOSED HERE IS THE DEVELOPMENT OF A NEW TYPE OF RADIATION-DISCRIMINATING, LONG-WAVELENGTH INFRARED (LWIR) DETECTOR BASED ON IMPURITY-BAND-CONDUCTION (IBC). THE NEW CONFIGURATION ENABLES ONE TO DISCRIMINATE BETWEEN GAMMA-RAY AND LWIR-INDUCED EVENTS. PAST USE OF IBC PHOTODETECTORS HAS SHOWN THAT INJECTED DARK CURRENT FROM THE CONTACTS IS A MAJOR PROBLEM LIMITING THEIR USE. FOR THE I ...

THE OBJECTIVE OF THIS PHASE I RESEARCH IS TO DEVELOP A COMPUTATIONAL PROCEDURE FOR PREDICTING THE LIFE AND RELIABILITY OF COMPOSITE STRUCTURAL PANELS SUBJECTED TO COMPLEX DYNAMIC LOADS FROM ACOUSTIC, AERODYNAMIC, AND THERMAL ENVIRONMENTS. THE PROPOSED RESEARCH USES A NONCLASSICAL VARIATIONAL APPROACH AND A TIME DOMAIN MONTE CARLO METHOD TO DEVELOP ANALYTICAL EQUATIONS OF HIGH ACCURACY AND EFFICIEN ...

THEORETICAL CHEMISTRY TECHNIQUES ARE USED TO PROVIDE FUNDAMENTAL UNDERSTANDING OF THE MOLECULAR REQUIREMENTS FOR ACHIEVING CONDUCTIVE PROPERTIES IN POLYMER SYSTEMS AND IN A LATER STAGE TO ADDRESS THE REQUIREMENTS FOR ACHIEVING NONLINEAR OPTICAL PROPERTIES. IT IS PROPOSED TO DEDUCE THE CONDUCTION MECHANISM BY CALCULATING THE CONDUCTIVITY TENSOR DIRECTLY AND ANALYZING THE DIFFERENT CONTRIBUTIONS TO ...

THE OBJECTIVE OF THE ELECTROMAGNETICALLY LEVITATED STABLE PLATFORM (ESP) EFFORT IS THE DEVELOPMENT OF A COMPACT AND FLEXIBLE TWO-AXES STABILIZED SENSOR PLATFORM FOR MANNED OBSERVATIONS OF THE EARTH OR SKY FROM SPACE UTILIZING AURA SYSTEMS' UNIQUE ELECTROMAGNETIC LEVITATION TECHNOLOGY. ESP REPRESENTS THE FIRST APPLICATION OF ELECTROMAGNETIC LEVITATION TECHNOLOGY TO A STABILIZED PLATFORM SPECIFICALL ...

THE IFM IS ALMOST AN IDEAL RECEIVER FOR THE INTERCEPTION OF RADAR THREATS EXCEPT THAT IT CANNOT PROCESS MULTIPLE SIMULTANEOUS SIGNALS. A RECENTLY PROPOSED APPROACH USING CORRELATOR ARRAY SHOWS GOOD POTENTIAL OF RESOLVING THIS MAJOR DEFICIENCY. THIS PROPOSED EFFORT IS TO INVESTIGATE, ACCESS AND COMPARE DIFFERENT OPTICAL SIGNAL PROCESSING TECHNIQUES FOR THE IMPLEMENTATION OF IFM CORRELATORS. SEVERAL ...
