THE ANALYSIS OF AEROBALLISTIC RANGE DATA IS A TEDIOUS AND TECHNICALLY CHALLENGING TASK. THE SOPHISTICATED ANALYSIS PROCEDURES AND REQUIRED SOFTWARE (COMPUTER PROGRAMS) HAVE BEEN REFINED EXTENSIVELY DURING THE PAST FIFTEEN TO TWENTY YEARS WITH THE ADDITION OF THE SIX-DEGREE-OF-FREEDOM CODES EMPLOYING THE MAXIMUM LIKELIHOOD METHOD. THE REQUIRED PROFICIENCY TAKES BETWEEN THREE AND FIVE YEARS UNDER TH ...

BORON NEUTRON CAPTURE THERAPY (BNCT) HAS A CLEAR THEORETICALADVANTAGE OVER OTHER TECHNIQUES AS A METHOD OF DELIVERING CELL KILLING RADIATION TO TUMORS. NEW BORON COMPOUNDS ARE NEEDED THAT CAN SELECTIVELY LOCALIZE IN TUMORS AND, UPON CAPTURE OF THERMAL OR EPITHERMAL NEUTRONS, PRODUCE RADIATIONTO KILL TUMOR CELLS BUT SPARE NORMAL TISSUE AND BLOOD. BNCTEFFECTIVENESS WOULD BE GREATEST IF THE BORON TAR ...

N/A

SILICON CARBIDE POSSESSES A UNIQUE COMBINATION OF PROPERTIES THAT ALLOW SIMULTANEOUS HIGH TEMPERATURE AND HIGH POWER OPERATION OF ELECTRONIC DEVICES MADE FROM THIS MATERIAL. THE CUBIC FORM OF SIC (BETA) HAS A WIDE BANDGAP (2.2 EV @ 27 DEG C), WHICH THEORETICALLY GIVES A MAXIMUM OPERABLE TEMPERATURE OF 925 DEG C. ALPHA SIC (6H) HAS AN EVEN WIDER BANDGAP OF 2.86 EV @ 27 DEG C, GIVING A MAXIMUM OPERA ...

A NEW CLASS OF EXTREMELY FAST SINGLE-CHIP SIGNAL PROCESSORS BASED ON THE EMERGING TECHNOLOGY OF ACOUSTIC CHARGE TRANSPORT (ACT) HAS RECENTLY BECOME AVAILABLE THROUGH AN INTENSE DEVELOPMENT EFFORT BY DARPA AND THE U.S. AIR FORCE. ONE APPLICATION OF THIS NEW TECHNOLOGY IS THE MULTIPLEXING AND PROCESSING OF IR FOCAL PLANE SIGNALS FOR STARTING AND SCANNING ARRAYS. THE PROPOSED PROGRAM SEEKS TO DEVELOP ...

THIS PROPOSAL IS FOR THE DESIGN OF A COVERT COMMUNICATIONS SYSTEM BASED ON ACOUSTIC CHARGE TRANSPORT (ACT) FILTER TECHNOLOGY. THIS SYSTEM IS COVERT IN THAT A NEARBY UNFRIENDLY RECEIVER WILL BE UNLIKELY TO DISCOVER THE PRESENCE OF THE TRANSMITTED SIGNAL, WHILE A MORE-DISTANT FRIENDLY RECEIVER WILL ONLY DETECTS THE SIGNAL, BUT ALSO MAINTAINS AN ADEQUATE SIGNAL-TO-NOISE RATIO. THE TECHNICAL APPROACH ...

THIS PROPOSAL DESCRIBES A PROGRAM FOR THE DEVELOPMENT OF A FREQUENCY CHANNELIZER AND PROCESSOR FOR ESM, ECM, COMMUNICATIONS, OR SURVEILLANCE APPLICATIONS. THIS SYSTEM IS BASED ON THE EMERGING TECHNOLOGY OF ACOUSTIC CHARGE TRANSPORT (ACT) WHICH ALLOWS THE FUNCTIONS OF FILTERING, DELAY, DETECTION, AND SWITCHING TO BE PERFORMED ON A SINGLE GALLIUM-ARSENIDE CHIP. THE PROPOSED PHASE I PROGRAM SEEKS TO ...

TWO OR MORE FREQUENCY HOP RADIOS OPERATING IN A COMMON SITE CREATE A SUBSTANTIAL INTERFERENCE PROBLEM BECAUSE CONVENTIONAL FIXED FILTERING TECHNIQUES WITHOUT FREQUENCY AGILITY CANNOT BE USED TO SUPPRESS IT. A NEW ENABLING TECHNOLOGY CALLED ACOUSTIC CHARGE TRANSPORT (ACT) HAS GIVEN RISE TO A FAMILY OF PROGRAMMABLE FILTERS THAT HOLD PROMISE FOR REDUCING THIS INTERFERENCE PROBLEM. THE PROGRAMMING TIM ...

THIS PROGRAM IS DIRECTED TOWARD DEVELOPING THE SCIENTIFIC AND TECHNICAL INSIGHT NEEDED TO EVALUATE A SOLID OXIDE FUEL CELL COMPATIBLE WITH PROMOTING, AT A BIFUNCTIONAL ANODE, THEOXIDATIVE DIMERIZATION OF METHANE TO ETHYLENE. FOR ETHYLENEAS AN ANODIC REACTION PRODUCT, THE OVER-ALL ELECTROCHEMICAL REACTION WILL BE SPONTANEOUS, RESULTING IN THE SIMULTANEOUS GENERATION OF ELECTRICAL ENERGY. THIS WORK ...
