ALGORITHMS ARE DERIVED THAT DEFINE THE PATHS OF MAXIMUM COHERENCY FOR A SEISMIC EVENT GENERATED BY FIRING AN ARTILLERY WEAPON FROM AN ARBITRARY LOCATION. SIGNAL EXTRACTION TECHNIQUES ARE DESCRIBED TO EXTRACT THE COHERENT SIGNAL FROM AN EVENT RECORDED ON MULTIPLE RECEIVERS. SIMULATED BATTLEFIELD RECORDINGS ARE GENERATED BY TREATING THE SEISMIC SIGNATURE OF ARTILLERY WEAPONS AS IMPULSE RESPONSES FRO ...

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...

THIS PROPOSAL ADDRESSES THE TECHNICAL CHALLENGE TO U.S. INDUSTRY FOR DEVELOPMENT OF CONTROL SYSTEMS THAT ARE ADAPTABLE TO CHANGES IN THE COMPLEX MULTIPLE, CONCURRENT PROCESSES OF A SEMICONDUCTOR MANUFACTURING ENVIRONMENT. THE PROPOSED WORK IS EXPLORATORY RESEARCH WHICH WILL RESULT IN THE DEVELOPMENT OF AN ABSTRACT SETTING FOR THE CONTROL SYSTEMS, INVOLVING A THREE TIER HIERARCHICAL APPROACH, WITH ...

A NEW AND INNOVATIVE CLASS OF ADAPTIVE COMPUTATIONAL PROCEDURES IS TO BE DEVELOPED FOR THE SPECIFIC PURPOSE OF NUMERICALLY-MODELING COMPLEX FLOWS INHERENT IN ADVANCED HELICOPTER-BLADE DESIGNS. THESE PROCEDURES MAKE USE OF MATHEMATICALLY CONSISTENT ESTIMATES OF LOCAL NUMERICAL ERROR, AND AUTOMATICALLY REFINE OR UNREFINE THE MESH OR INCREASE OR DECREASE THE LOCAL SPECTRAL ORDER OF THE APPROXIMATION ...

PROPOSAL FOR UTILIZING SOLID STATE PIEZO-RESISTIVE SENSORS TO MEASURE AND RECORD CUMULATIVE WHEEL ROTATIONS. WHEEL ROTATION IS SENSED BY EXPLOITING THE FORCE DUE TO NORMAL (CENTRIPETAL) ACCELERATION, WHICH IS A FUNCTION OF THE ROTATIONAL SPEED SQUARED. THE ELECTRONIC PACKAGE IS SMALL (INCORPORATING SMT) AND CONSISTS MAINLY OF THE SENSOR AND A MOTOROLA F68HC11 MICROPROCESSOR. THE MICROPROCESSOR IS ...

INCREASES IN SOLAR CELL EFFICIENCY CAN BE ACHIEVED WITH TANDEM MULTI-JUNCTION STRUCTURES TO IMPROVE THE PERFORMANCE AND SCALE OF SPACE PHOTOVOLTAIC CONCENTRATORS. THE "TOP SOLAR CELL" TANDEM APPROACH COULD INCREASE ENERGY CONVERSION EFFICIENCY BY AS MUCH AS 100%. A SELF-SUPPORTING ALUMINUM-GALLIUM-ARSENIDE (ALGAAS) TOP SOLAR CELL IS BEING DEVELOPED FOR MECHANICAL ATTACHMENT TO A SILICON CONCENTRAT ...

THE GOAL OF THIS RESEARCH PROGRAM IS TO DEVELOP A NEW AND CHEAPER METHOD FOR PRODUCING PENTAFLUOROTHIO (SF5) SUBSTITUTED FUNCTIONAL FLUOROCARBONS. THESE MATERIALS HAVE POTENTIAL AS BUILDING BLOCKS FOR ENERGETIC MATERIALS. THEY WILL BE PRODUCED BY THE CONTROLLED REACTION OF SULFUR SUBSTITUTED HYDROCARBONS WITH ELEMENTAL FLUORINE.

THIS PROPOSAL INVOLVES THE USE OF ENCAPSULATED MICRODROPLETS TO BE EMPLOYED AS A PASSIVE DOSIMETER BADGE FOR HCL MEASUREMENTS. THE DROPLETS WILL CONTAIN PH SENSITIVE DYE MOLECULES DISSOLVED IN HOST LIQUID CRYSTAL MOLECULES. PERMEATION OF HCL MOLECULES THROUGH THE ULTRATHIN ENCASING POLYMERIC SKIN OF THE DROPLETS WILL RESULT IN A PH DRIVEN COLOR CHANGE. THIS COLOR CHANGE, AND HENCE TOTAL HCL EXPOSU ...

AN ARRAY COMMUNICATIONS COPROCESSOR (ACC) ARCHITECTURE HAS BEEN DEVELOPED THAT PROVIDES AUTOMATIC, ADAPTIVE, AND DYNAMICALLY CONFIGURABLE INTER-PROCESSOR COMMUNICATIONS AND IS COMPATIBLE WITH MOST COMMERCIALLY AVAILABLE STATE-OF-THE-ART COMPLEX INSTRUCTION SET COMPUTERS (CISC) AND REDUCED INSTRUCTION SET COMPUTERS (RISC). IN THIS INVESTIGATION, THE ARRAY COMMUNICATIONS CONTROLLER IS BEING IMPLEMEN ...

WE PROPOSE A STUDY TO EXPLORE THE POSSIBILITY OF DEVELOPING AN IMPROVED TECHNIQUE TO AUTOMATICALLY COMPRESS AN IMAGE AND EXTRACT FEATURES THAT REPRESENT THE IMAGE, OR PARTS OF IT, IN TERMS OF A FEW RELATIONSHIPS CHARACTERIZED BY FRACTALS. WE PLAN TO USE EXISTING TOOLS OF FRACTAL GEOMETRY LIKE HAUSDORFF DIMENSION, ATTRACTORS OBTAINED BY ITERATED FUNCTION SYSTEMS, FRACTAL INTERPOLATION FUNCTIONS TO ...
