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 MODEL FOR PREDICTING THE PERFORMANCE IMPACT OF ENGINE DETERIORATION IS PROPOSED FOR FEASIBILITY EVALUATION. THIS MODEL WOULD ACCOUNT FOR ROTATING COMPONENT DETERIORATION SUCH AS INCREASED TIP CLEARANCES, SURFACE ROUGHNESS, LEADING EDGE BLUNTNESS AND VAN BOW AND TWIST. THE PROPOSED APPROACH USES A STAGE STACKING METHOD TO ALLOCATE LOSSES THROUGHOUT THE ENGINE WHICH ARE DEPENDENT ON OPERATING TIME ...

MASSIVELY INTERCONNECTED COMPUTERS, COMMONLY CALLED NEUROCOMPUTERS, ARE AT THE HEART OF SIXTH-GENERATION COMPUTING. TO DATE, HOWEVER, ONLY NEUROCOMPUTER SIMULATORS AND EMULATORS ARE AVAILABLE. THIS RESEARCH PROJECT WILL DEVELOP TOOLS AND TECHNIQUES TO TRANSLATE NEUROCOMPUTERS INTO COMPUTATIONALLY EQUIVALENT DIGITAL VLSI CIRCUITS. CONCEPTS FROM SWITCHING CIRCUIT THEORY WILL BE USED TO TRANSLATE IND ...

THE ABILITY TO GROW HETEROSPITAXIAL THIN FILMS OF DIAMOND IS LIMITED IN PART BY THE PROPENSITY OF SUCH FILMS TO NUCLEATE AT MULTIPLE SITES WITHOUT PROPER ORIENTATION. WE PROPOSE TO DEVELOP A 2-DIMENSIONAL GROWTH PROCESS BY ATOMIC LAYER EPITAXY (ALE) USING ADVANCED MOLECULAR BEAM TECHNIQUES. THE PHASE I RESEARCH WILL FOCUS ON DETERMINING THE MICROCHEMISTRY OF DEPOSITION PROCESSES AND THUS ALLOW FOR ...

WE PROPOSE TO DEMONSTRATE AN OPTICAL ANALOG-TO-DIGITAL CONVERTER FOR MICROWAVE ANALOG SIGNALS WHICH UTILIZES A SINGLE ELECTROOPTIC BROADBAND VELOCITY MATCHED TRAVELLING WAVE MODULATOR BUT WITH MULTIPLE PULSED OPTICAL BEAMS TO SAMPLE THE SIGNAL AND MULTIPLE STANDARD ELECTRONIC A/D'S TO ACCOMPLISH THE CONVERSION IN PARALLEL. THE DIGITAL OUTPUT WORDS APPEAR ON MULTIPLE SETS OF LINES APPROPRIATE FOR A ...

THE POLARIZATION CHARACTERISTICS OF AIRCRAFT INFRARED SIGNATURES HAVE BEEN STUDIED AS A MEANS TO ENHANCE THE PERFORMANCE OF LONG RANGE PASSIVE INFRARED DETECTION SYSTEMS OPERATING IN THE PRESENCE OF CLUTTER. THESE STUDIES ALSO GENERATED EVIDENCE THAT THE AMOUNT AND ANGLE OF POLARIZATION AS WELL AS ITS SPATIAL DISTRIBUTION ARE UNIQUE BETWEEN DIFFERENT TYPES AND CLASSES OF AIRCRAFT. IT MAY BE POSSIB ...

THE PROPOSED PROGRAM WOULD PROVIDE THE AIR FORCE BALLISTIC SYSTEMS DIVISION (BSD) WITH AN ENGINEERING LEVEL SIGNATURE MODELING CAPABILITY FOR VARIOUS TYPES OF REENTRY VEHICLES (RVS) DURING THE MIDCOURSE PHASE. THE PRESENT AERODYNE RESEARCH, INC. (ARI) SPIRITS SIGNATURE MODEL OFFERS THE BASSIS FOR THE MODELING CAPABILITY IN THE ULTRAVIOLET (UV) THROUGH THE INFRARED (IR) SPECTRUM. THE SPIRITS MODEL ...
