ANY VERY HIGH LEVEL LANGUAGE (VHLL) FOR STRATEGIC DEFENSE REQUIRES A COMPILER. NEW META COMPILERS USING ADVANCED ARTIFICIAL INTELLIGENCE METHODS ARE BEING STUDIED SO THAT EVENTUAL VHLL APPLICATION SOFTWARE CAN BE EFFECTIVELY PORTED TO THE SEVERAL GROUND-BASED/SATELLITE-BASED MACHINES. TO DO SO REQUIRES A META COMPILER THAT CAN COMPILE CODE TO DIVERSE ARCHITECTURES. RESEARCH WITH META COMPILERS DEM ...

POLYMERIC OR CERAMIC INSULATORS CONVENTIONALLY ARE BEING USED IN HIGH VOLTAGE PULSED SYSTEMS. NEW APPROACHES ARE NEEDED THAT WOULD REDUCE INSULATORS RING THICKNESSES AND INCREASE CORRESPONDING GRADING RINGS FLASHOVER VOLTAGE. SUCH AN APPROACH WOULD POSSESS IN COMPARISON TO CONVENTIONAL INSULATORS: HIGHER SURFACE FLASHOVER FIELD STRENGTH; SMALLER PHYSICAL DIMENSIONS FOR EQUIVALENT VOLTAGE HOLDOFF; ...

THE DEVELOPMENT OF HIGH POWER, LOW IMPEDANCE, LIGHTWEIGHT ENERGY STORAGE TRANSMISSION LINES FOR PULSE-POWER APPLICATIONS IS CRUCIAL FORSMALLER, LIGHTWEIGHT, SPACE-BASED, PULSE-POWER SYSTEMS. DEVELOPMENT OF HIGH DIELECTRIC ENERGY STORAGE LINE TECHNOLOGY WOULD GREATLY REDUCETHE SIZE, WEIGHT, AND COMPLEXITY OF PULSE POWER SYSTEMS UTILIZING THESE TYPES OF COMPONENTS. EFFICIENT TRANSPORT OF 400KV, 100K ...

There are no commercial amplifiers that can operate at temperatures above 125 degrees Celsius. We will combine two comparable wide bandgap semiconducting materials to make electronic amplifiers and switches that operate at high temperatures (at least 500 degrees Celsius). These devices can be controlled remotely by a light beam. Hence wireless coupling to a room temperature macroprocessor is possi ...

THE EXISTING METHODOLOGY OF DESIGN AND FABRICATION OF SEMICONDUCTOR MANUFACTURING EQUIPMENT IS AN EXPENSIVE AND TIME CONSUMING PROCESS. TO KEEP PACE WITH THE RAPIDLY ADVANCING SEMICONDUCTOR INDUSTRY, IT IS NECESSARY TO DEVELOP A COMPUTER BASED ENVIRONMENT TO QUICKLY SIMULATE THE FEATURES OF THE MANUFACTURING EQUIPMENT BEFORE IT IS TURNED INTO A PHYSICAL PROTOTYPE. APART FROM ACHIEVING CONSIDERABLE ...

REMOTE SENSING OF VIBRATIONS USING COHERENT LASER RADAR (CLR) HAS BEEN IDENTIFIED AS A MEANS OF IDENTIFYING REMOTE TARGETS BY ANALYSIS OF CHARACTERISTIC VIBRATION SPECTRA. CO2 LASER TECHNOLOGY HAS BEEN USED IN EFFORTS UP TO THE PRESENT. RECENT ADVANCES IN EYESAFE ( 1.4 UM) SOLID-STATE LASER AND LASER RADAR TECHNOLOGY POINT TO A MORE SENSITIVE, COMPACT, SHORTER WAVELENGTH ALTERNATIVE, HIGHLY COMPAT ...

CONTRACTOR WILL EXAMINE THE FEASIBILITY OF UTILIZING PULTRUSION-TYPE CONTINUOUS TAPE LAYING MANUFACTURING EQUIPMENT TO FABRICATE COMPOSITE SANDWICH STRUCTURE WINGS AND STABILIZERS FOR CLOSE RANGE AND SHORT RANGE CLASS UNMANNED AERIAL VEHICLES. DURING PHASE I A SMALL PROOF-OF-CONCEPT MANUFACTURING MACHINE WILL BE DESIGNED, BUILT, AND EVALUATED. IN ADDITION, THE QUALITY OF THE MANUFACTURED PRODUCT F ...

FABRICATING CERAMIC PROTOTYPES OR MANUFACTURING LOW VOLUME QUANTITIES OF CERAMIC PARTS IS A COSTLY, TIME-CONSUMING, AND INFLEXIBLE PROCESS. THESE RESTRICTIONS LIMIT THE USE OR EVEN THE CONSIDERATION OF CERAMICS IN SOME APPLICATIONS. A VARIETY OF TECHNIQUES HAVE BEEN DEVELOPED TO PRODUCE PAPER- AND POLYMER-BASED PARTS DIRECTLY FROM A COMPUTER-AIDED DRAWING WITHOUT ANY HARD TOOLING, DIES, OR MOLDS. ...

AN ACCURATE KNOWLEDGE OF THE MAXIMUM FIBER STRESS OCCURRING DURING PAYOUT IS CRITICAL TO IMPROVE THE RELIABILITY OF CURRENT AND FUTURE DISPENSER DESIGNS FOR FIBER OPTIC GUIDED VEHICLES. THE FIBER DEFORMATIONS OCCURRING AT THE PEEL POINT ARE A DIRECT INDICATION OF THE MAXIMUM FIBER STRESSES UNDER NORMAL PAYOUT CONDITIONS. IN ADDITION, THE FIBER DEFORMATIONS AT THE PEEL POINT PROVIDE AN INVALUABLE M ...

A compact x-ray laser driver with a high repetition rate is the subject of this phase I project. Most existing x-ray laser drivers are huge (1000s of square feet of floor space), expensive ($10,000,000+), have a low repetition rate (1/hr), are complex and require several PhDs to keep them working. Thus applications of present x-ray lasers are limited. In contrast, the proposed laser will occupy on ...
