A PHASE I EFFORT IS PROPOSED TO INTEGRATE PREVIOUS WORK AND DEVELOP THE NEEDED RESEARCH BASE TO ASSESS AND DEVELOP STOCHASTIC METHODS FOR PROTECTIVE DESIGN FOR NON-NUCLEAR WEAPONS. THE CORNERSTONE OF THIS EFFORT WILL BE THE DEVELOPMENT OF A RELIABILITY-BASED DESIGN (RBD) PROCEDURE. THERE ARE SEVERAL WELL DEVELOPED RBD PROCEDURES (LOAD AND RESISTANCE FACTORS, FIRST-ORDER SECOND-MOMENT, AND MONTE CA ...

AN "INTELLIGENT" MECHANISM TO CONTROL AIRCRAFT TURBINE ENGINE COOLDOWN UTILIZING INTEGRAL SENSORS, LOGIC, DRIVE AND FAIL-SAFE, FOR EXTENDING THE PERFORMANCE LIFE OF AIRCRAFT GAS TURBINE ENGINES IS PROPOSED. AIRCRAFT TURBINE ENGINES ARE PRECISELY MADE AND CONTROLLED MECHAISMS UNTIL SHUTDOWN. THEN, HEAT SOAK AND SOAKBACK PHENOMEN DELETERIOUSLY AFFECT ENGINE PERFORMANCE, LIFE, MAINTENANCE COSTS AND L ...

THE PROGRAM GOALS FOR THE EGRESS BORING MACHINE REQUIRE A ROCK BORING SYSTEM WHICH WILL PRODUCE PENETRATION RATES OVER TEN TIMES GREATER THAN THOSE PRODUCED TO DATE UNDER SIMILAR CONDITIONS. THIS PROPOSAL IS TO DEVELOP A CUTTER SYSTEM WHICH USES THE CONCEPT OF AN INTERRUPTED DISC CUTTER. IT WILL TAKE FULL ADVANTAGE OF INDEXING BETWEEN CRATERS TO MAXIMIZE ROCK REMOVAL WHILE MINIMIZING THRUST REQUIR ...

THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

THE GOAL OF THIS RESEACH PROGRAM IS TO BETTER UNDERSTAND THE RELATION-SHIP BETWEEN OXIDATIVE STABILITY AND STRUCTURE AS IT RELATES TO PERFLUOROPOLYETHERS. WE INTEND TO USE DIRECT FLUORINATION TECHNOLOGY TO PRODUCE SEVERAL NEW PERFLUOROPOLYETHER FLUIDES WHICH CONTAIN UNIQUE ARRANGEMENTS OF CARBON AND OXYGEN IN THE BACKBONE OF THE POLYMER AS WELL AS UNUSUAL PENDANT GROUPS. THE DIRECT FLUORINATION PR ...

THIS SBIR PROPOSAL DESCRIBES A PROJECT IN WHICH TECHNIQUES ARE DEVELOPED FOR APPLYING EXPERT SYSTEMS THAT AID CLINICIANS DURING INTERPRETATION OF NUCLEAR MEDICINE AND PHOTOGRAPHIC IMAGES, AS WELL AS PHYSIOLOGICAL ANALOG SIGNALS SUCH AS ELECTROCARDIOGRAMS. THE TECHNIQUES WHICH EMBODY ACCEPTED AND PROVEN KNOWLEDGE BASES AND AN ACCEPTED REASONING MECHANISM SERVE AS A STANDARD BY WHICH FUTURE DIAGNOSI ...

EXISTING GLASS MATRIX LASERS UTILIZE NEODYMIUM DOPING OF A SILICATE MATRIX. THE INABILITY TO USE A SIO2 MATRIX RESULTS IN AN EFFICIENCY OF 3% OR LESS. THE LOW THERMAL CONDUCTIVITY OF GLASS COUPLED WITH THE RELATIVELY HIGH COEFFICIENT OF THERMAL EXPANSION OF THE SILICATES LIMITS THE OUTPUT INTENSITY AND PULSE RATE IN ORDER TO PREVENT DEDOCUSING AND FILAMENTARY BREAKDOWN FROM THE THERMAL EFFECTS. TH ...

NONDESTRUCTIVE EVALUATION OF MUNITIONS PRESENTS SPECIAL PROBLEMS THAT CANNOT BE SOLVED WITH CONVENTIONAL TECHNIQUES. AN ELECTRONIC X-RAY IMAGING SYSTEM WILL BE STUDIED TO DETERMINE THE FEASIBILITY OF ITS USE IN ADVANCED RADIOGRAPHIC IMAGING TECHNIQUES SUCH AS REMOTE ON-LINE INSPECTION, MULTISPECTRAL RADIOGRAPHY AND BACKSCATTER TOMOGRAPHY.

A PROJECT IS PROPOSED WHICH WILL INVESTIGATE THE REQUIREMENTS OF A 32-BIT MILITARIZED PROCESSING MODULE WITH AN INSTRUCTION SET ARCHITECTURE THAT WILL EFFICIENTLY PERFORM BOTH AI AND ADA-TYPE PROCESSING AND BE COMPATIBLE WITH APPLICABLE BACKPANEL BUS STANDARDS. THE PROPOSED PROJECT WILL RESEARCH CURRENTLY AVAILABLE MICROPROCESSORS WHOSE ARCHITECTURES LEND THEMSELVES TOWARD EXTENSIBILITY OF AI/ADA ...
