BY OPTIMIZING CONDITIONS, CONVENTIONAL ELECTRON BEAM BY OPTIMIZING CONDITIONS, CONVENTIONAL ELECTRON BEAM RESISTS, SUCH AS PBS, CAN BE USED TO PRODUCE GEOMETRIES IN THE 0.3 TO 0.5 MICRON RANGE IN A CONTROLLED MANNER, USING RASTER SCAN WRITING TECHNIQUES IN A LIMITED PRODUCTION ENVIRONMENT. IN ORDER FOR THESE PATTERNING TECHNIQUES TO BE USEFUL, THE DEFECT DENSITY OF THE FINAL PRODUCT MUST BE VERY T ...

INTENSE, FINELY-FOCUSSED ION BEAMS WOULD FIND MANY APPLICATIONS IN RESEARCH AND PRODUCTION IF SUFFICIENTLY BRIGHT ION SOURCES COULD BE MADE. THE PROPOSED RESEARCH IS AN INVESTIGATION OF THE FEASIBILITY OF A CONCEPT FOR AN EXTREMELY BRIGHT ION SOURCE WHEREIN AN INTENSE SUPERSONIC MOLECULAR BEAM IS IONIZED AND IONS ARE CAREFULLY EXTRACTED FROM A SYNTHETIC PLASMA. THE TOPICS TO BE INVESTIGATED ARE TH ...

A SYSTEM IDENTIFICATION TECHNICAL IS PROPOSED FOR NON-DESTRUCTIVE TEST TO DETECT UNBOUNDS IN LARGE BONDED COMPONENTS. THE TECHNIQUE USES THE SYSTEM'S TIME RESPONSE DATA DUE TO RANDOM INPUT EXCITATION. SYSTEM'S EIGENVALUES AND EIGENVECTORS ARE RETRIEVED FROM THE TIME RESPONSES AND USED FOR THE CONSTRUCTION OF ACCURATE SYSTEM MATHEMATICAL MODELS. SYSTEM'S CHANGE DUE TO CRACKS, VOIDS, UNBONDS BETWEEN ...

METHODS ARE DESPERATELY NEEDED TO DISCERN THE STRUCTURAL INTEGRITY OF CRITICAL COMPONENTS OF WEAPON SYSTEMS SUCH AS PRESSURE VESSEL CASES. AT THIS TIME, NO TECHNIQUE EXISTS WHICH PERMITS A GLOBAL MONITORING OF THE OPERATIONAL READINESS OF ANY STRUCTURES, INCLUDING COMPOSITE MOTOR CASES. THE RANDOMDEC PROCEDURE, WHICH IS PLANNED TO BE UTILIZED UNDER THIS PROPOSED STUDY, APPEARS TO HAVE THE CAPABILI ...

THE DOD SOFTWARE INITIATIVE CLEARLY IDENTIFIED THE CHALLENGES FOR FUTURE SYSTEMS. THEY WILL HAVE TO BE LARGER AND MORE COMPLEX, DEVELOPED AND DELIVERED MORE RAPIDLY, AND MAINTAINED OVER LONGER PERIODS. TRADITIONAL PROGRAMMING TECHNIQUES, HOWEVER, APPEAR TO HAVE REACHED THEIR LIMITS, MAKING MUCH LARGER SOFTWARE SYSTEMS VIRTUALLY IMPOSSIBLE TO BUILD AND MAINTAIN. AN ALTERNATIVE APPROACH, CALLED FUNC ...

A MERGER OF TECHNOLOGIES INVOLVING A) POLYMER FIBER OPTICS, B) POLYMER PHTHALOCYANI PHOTO VOLTAICS AND C) ELECTRODE CELL ADHESION SURFACES HAS RESULTED IN THE CONCEPT OF A NOVEL ELECTRODE PROSTHESIS WHICH USES FINE 5-10 W POLYMER OPTICAL FIBERS INSTEAD OF METAL WIRES. USING A PHOTO CONVERSION MECHANISM AT THEIR ENDS, THESE FIBERS CONVERT LIGHT ENERGY TO A NEGATIVE ELECTRICAL PULSE IN THE 100 MV RA ...
