WE PROPOSE A UNIQUE METHOD TO DETECT BOTH CONVENTIONAL AND LOW-OBSERVABLE AIRCRAFT AND MISSILES. THE METHOD RELIES ON NONE OF THE TYPICALLY USED SIGNATURES (I.E., THERMAL, RADAR, ELECTRONIC, VISUAL, AUDIO, OR CONTRAIL) AND THUS WOULD BE IMMUNE TO ALL THE PRESENTLY EXISTING DECOYS AND COUNTERMEASURES. THE SENSOR SPECIFICALLY DETECTS AND MEASURES THE RELATIVE CONCENTRATION AND CHEMICAL SIGNATURE OF ...

ARTIFICIAL NEURAL NETWORKS (ANN) HAVE PROVEN CAPABILITY IN FORWARD ERROR CORRECTION (FEC) ENCODING AND DECODING. THIS PROPOSAL STRIVES TO ADDRESS THE POTENTIAL THAT ANNS MAY ENABLE NON-COOPERATING RECEIVERS TO IDENTIFY, CONFIGURE, AND RECOVER INFORMATION FROM A COMPLEX COMMUNICATION CHANNEL. MODERN DIGITAL COMMUNICATION SYSTEMS HAVE BEEN DESIGNED TO TRANSMIT DATA AT EXTREMELY HIGH RATES - SOMETIME ...

VEXCEL CORPORATION PROPOSES A PHASE I RESEARCH EFFORT FOR THE ANALYSIS AND PRELIMINARY SIMULATION OF A NOVEL METHOD FOR DETECTING HIGH-VOLTAGE POWER LINES AND TOWERS IN UNFRIENDLY REGIONS USING MULTIPLE FLIGHT-PATH SYNTHETIC APERTURE RADAR (SAR) IMAGERY. THE PROPOSED METHOD CONSISTS OF ADAPTING THE ESPIRIT ALGORITHM FOR ESTIMATION OF ELEVATION ANGLE-OF-ARRIVAL TO SYNTHESIZE A 2-D ARRAY FROM THE MU ...

THE USE OF ARSINE FOR THE GROWTH OF GAAS EPITAXIAL LAYERS BY METALORGANIC CHEMICAL VAPOR DEPOSITION (MOCVD) IS COMING UNDER INCREASING SCRUTINY BY GOVERNMENT AGENCIES AND COMMUNITIES. THE EXTREME TOXICITY OF ARSINE GAS, WHICH MUST BE STORED IN HIGH-PRESSURE STEEL CYLINDERS, COULD LEAD TO CATASTROPHIC CONSEQUENCES IN CASE OF AN ACCIDENTAL RELEASE OF A LARGE QUANTITY OF ARSINE. IN THE FUTURE, USE OF ...

EXTENSIVE SWITCHING AND MEMORY STUDIES HAVE BEEN MADE IN THE PAST ON THICK FILMS (10 TO 200 MM) OF DOPED XXXX FERROELECTRIC CERAMINCS. PARTICULAR COMPOSITIONS WITHIN THIS CERAMIC FAMILY WERE FOUND TO BE GREATLY SUPERIOR TO COMPARABLE THICK FILMS OF PZT. THE XXXX FERROELECTRIC THICK FILMS HAD ENDURANCES TWO TO FIVE ORDERS OF MAGNITUDE GREATER, LOWER COERCIVE VOLTAGES, LOWER PIEZOELECTRIC ACTIVITY A ...

THE FOLLOWING PROPOSAL COVERS A PROJECT TO CONDUCT RESEARCH WRITE NARRATIVE, INSTRUCTIONAL AND SHOOTING SCRIPTS, AND IDENTIFY FILM SITES FOR DEVELOPMENT OF AN INTERACTIVE VIDEO PREVOCATIONAL SELECTION INSTRUMENT. SELECTION PATHS AND TOUCH SCREEN INPUT WILL ENABLE BOTH INDEPENDENT USE BY INDIVIDUALS WIHT MENTAL RETARDATION (CLASSIFIED "TRAINABLE")AND USE OF THE INSTRUMENT IN CONJUNCTION WITH A COUN ...

THERE IS A GROWING INTEREST IN THE ROLE OF NONLINEAR SIGNAL PROCCESSING (NSP) ALGORITHMS UTILIZING HIGHER-ORDER MOMENTS AND HIGHER-ORDER SPECTRAL MEASUREMENTS FOR FERRETING OUT INFORMATION ABOUT UNKNOWN SIGNALS THAT ARE BEYOND THE REACH OF LINEAR TECHNIQUES. NSP TECHNIQUES DISSECT HIGHER ORDER STATISTICAL SIGNAL STRUCTURE WHICH PERMIT ENHANCED DIFFERENTIATION FROM BACKGROUND. UNLIKE HEURISTICS, NS ...
