INNOVATIVE ARTIFICIAL INTELLIGENCE TECHNIQUES HAVE THE POTENTIAL TO SOLVE MANY COMPLEX AIR FORCE PROBLEMS. ADVANCES IN COMPUTING SPEED AND EXISTING SOFTWARE TECHNOLOGY ALONE ARE UNLIKELY TO RESULT IN REAL-TIME AERONAUTICAL SYSTEMS CAPABLE OF MEETING THE COMPLEX REQUIREMENTS OF THE AIR FORCE MISSION. RATHER, AN ALTERNATIVE METHODOLOGY SUCH AS ABDUCTIVE TECHNOLOGY, A NEW TECHNOLOGY PRESENTED IN THIS ...

A PRIMARY LIMITATION OF PHOTOELECTROCHEMICAL CELLS IS PHOTOCORROSION OF ELECTRODE MATERIALS. ONE SOLUTION TO THISPROBLEM HAS BEEN TO APPLY ELABORATE CONDUCTING POLYMERIC COATINGS TO SENSITIVE ELECTRODES. AN ALTERNATIVE IS TO USE CORROSION RESISTANT ELECTRODE MATERIALS. GROUP VI METAL DICHALCOGENIDES, AND TUNGSTEN DISELENIDE (WSE2) IN PARTICULAR, HAVE SHOWN PROMISE AS INTRINSICALLY CORROSION RESIST ...

RECENT DEVELOPMENTS IN OPTICAL COMMUNICATION TECHNOLOGY ARE VERY ENCOURAGING FOR THE POTENTIAL OPERATION OF OPTICAL SATELLITE CROSSLINKS. MOST NOTABLE IS THE DEVELOPMENT OF HIGH EFFICIENCY ND:YAG RING LASERS WHICH WOULD BE ATTRACTIVE TRANSMITTERS IF WIDE BANDWIDTH EXTERNAL PHASE MODULATORS COULD BE DEVELOPED. A TRAVELING-WAVE CONFIGURATION GIVES THE MAXIMUM BANDWIDTH FOR ELECTRO-OPTIC MODULATORS. ...

HIGH POWER SEMICONDUCTORS USING SILICON AND GAAS ARE LIMITED TO ENVIRONMENTS THAT ARE LESS THAN 300 DEG C IN TEMPERATURE DUE TO LOW BANDGAPS, LOW BREAKDOWN FIELDS AND LOW THERMAL CONDUCTIVITIES. 3C-SIC(B-SIC) HAS BEEN IDENTIFIED AS A MATERIAL WITH EXCELLENT POTENTIAL TO FULFILL THE REQUIREMENTS OF A HIGH POWER, HIGH TEMPERATURE SEMICONDUCTOR WITH HIGH RADIATION HARDNESS. THE KEY TO DEVELOPING DEVI ...

THE REPRODUCIBLE CRYSTAL GROWTH OF THIN FILMS WITH THE CORRECT STOICHIOMETRY AND APPROPRIATE MORPHOLOGY IS THE KEY TO THE COMMERCIALIZATION OF DEVICES INCORPORATING THIN FILM HIGH TEMPERATURE SUPERCONDUCTORS. MOCVD HAS THE POTENTIAL TO MEET THESE NEEDS COUPLED WITH RELATIVE EASE OF SCALING TOMANUFACTURING VOLUMES. HOWEVER, RECENT WORK ON MOCVD HAS BEEN PLAGUED BY TWO MAJOR LIMITATIONS: (1.) FILMS ...

A NOVEL DIAMOND DETECTOR FOR USE IN THE SOFT X-RAY TO THE VACUUM ULTRAVIOLET IS PROPOSED. THIS X-RAY DETECTOR IS BASED ON THE USE OF A DIAMOND FILM AS THE ACTIVE DETECTOR ELEMENT DUE TO DIAMOND'S HIGH INTRINSIC RESISTIVITY (LOW DARK CURRENT), LARGE CARRIER MOBILITIES, HIGH SATURATEDCARRIER DRIFT VELOCITY AND RADIATION AND CHEMICAL CORROSION RESISTANT CHARACTERISTICS. BECAUSE OF THESE CHARACTERISTI ...

ULTRAFAST SOLID STATE PHOTOCONDUCTIVE SWITCHES MAY NOW MAKE POSSIBLE PULSED ELECTRIC FIELDS ON THE ORDER OF 1GV/M ON TIME SCALES OF 1-100 PICOSECONDS. VOLTAGE GRADIENTS OF THISMAGNITUDE ARE BECOMING POSSIBLE THROUGH ADVANCES IN TRANSMISSION LINE DESIGN AND ULTRAFAST PHOTOCONDUCTIVE POWERSWITCHING TECHNOLOGY AND WILL PERMIT SIGNIFICANT ADVANCES INPRODUCING HIGHER ENERGY, COMPACT LINEAR ACCELERATORS ...
