MCNC PROPOSES A FEASIBILITY STUDY AND EVALUATION OF THREE PROMISING APPROACHES TO THE FABRICATION OF SURFACE TEST STRUCTURES ON SILICON. SURFACE FEATURES ON THE FIRST STRUCTURE WILL BE PRODUCED BY CONTROLLABLY ETCHING THERMALLYGROWN OXIDES. FEATURES ON THE SECOND WILL BE MADE BY ETCHING PIEZOELECTRIC THIN FILMS. USING THE PIEZOELECTRIC FILM AS PART OF A CAPACITOR, STEP-HEIGHT CAN BE VARIED AND PRO ...

A TECHNIQUE FOR OBTAINING TRUSTWORTHY COMPILATION BASED ON A COMPILATION CHECKER (SIMILAR TO A PROOF CHECKER) IS PROPOSED. THE TRANSFORMATIONS USED IN A COMPILER WILL BE FORMALLY SPECIFIED AND VERIFIED USING INTERPRETER EQUIVALENCE METHODS. THE COMPILER WILL BE INSTRUMENTED TO PRODUCE A TRACE OF THE TRANSFORMATIONS APPLIED IN THE COMPILATION OF A GIVEN PROGRAM. THE COMPILATION CHECKER WILL VALIDAT ...

THIS SBIR PHASE I PROPOSAL SPECIFICALLY ADDRESSED 'EARLY STAGE' DEVELOPMENT ISSUES INVOLVED IN APPLYING FIELD EMISSION (FEA) TECHNOLOGY TO BUILD A MONOCHROME, FLAT SCREEN, PAGE SIZE, HIGH CONTRAST, HIGH RESOLUTION DISPLAY. A 90 MM DIAGONAL 700 X 7000 LINE BLACK AND WHITE HE LMET DISPLAY IS THE TARGETED PHASE II PRODUCT. COLOR DISPLAYS AND 138 MM DIAGONAL DISPLAYS ARE TARGETED TO FOLLOW THE INITIAL ...

A PHASE I EFFORT IS PROPOSED TO INTEGRATE PREVIOUS WORK AND DEVELOP THE NEEDED RESEARCH BASE TO ASSESS AND DEVELOP STOCHASTIC METHODS FOR PROTECTIVE DESIGN FOR NON-NUCLEAR WEAPONS. THE CORNERSTONE OF THIS EFFORT WILL BE THE DEVELOPMENT OF A RELIABILITY-BASED DESIGN (RBD) PROCEDURE. THERE ARE SEVERAL WELL DEVELOPED RBD PROCEDURES (LOAD AND RESISTANCE FACTORS, FIRST-ORDER SECOND-MOMENT, AND MONTE CA ...

THE OBJECTIVE OF THIS PROPOSAL IS TO CONDUCT PRELIMINARY TESTS ON A NOVEL CHEMISTRY WHICH COULD RESULT IN THE PRODUCTION OF A LOW COST WAFER WHICH CHANGES COLOR UPON EXPOSURE TO WARFARE GASES (WG). SIMILAR WAFERS WHICH WE DEVELOPED FOR OTHER GASES ARE ABOUT 2" X 1" X 1/16" AND WEIGH ABOUT 2.3 GM. THESE CHROMOSENSE (TM) WAFERS CAN DETECT HYDROGEN SULFIDE, ETC. IN 10-30 SEC. AT CONCENTRATIONS OF THE ...

FUTURE MILITARY SPACE MISSIONS WILL REQUIRE 10-100 KILOWATTS OF SUSTAINED POWER WITH PEAK/PULSE POWER LEVELS OF 100 KW TO 100 MW. ELECTROCHEMICAL ENERGY STORAGE SYSTEMS WHICH CAN DELIVER HIGH POWER DENSITY YET OFFER HIGH ENERGY DENSITY NEED TO BE DEVELOPED. THESE RECHARGEABLE BATTERIES MUST HAVE DURABILITY AND COMPOSITION INVARIANCE FOR OVER 30,000 CYCLES. BOTH OF THE ELECTRODE REACTIONS IN THE ME ...

A PHASE I PROGRAM IS PROPOSED TO INVESTIGATE AND DEVELOP AN INNOVATIVE CLOTHING MATERIAL HAVING AN ENHANCED THERMAL ENERGY STORAGE CAPABILITY. PRESENT FABRICS THAT UTILIZE MULTIPLE LAYERS OF PASSIVE INSULATION OR ACTIVE ELECTRICAL HEATING ARE RESTRICTED BY EXCESSIVE BULK AND IMPAIRED DEXTERITY OR POWER LIMITATIONS AND BATTERY WEIGHT. A NOVEL APPROACH IS PROPOSED THAT WOULD PRODUCE SIGNIFICANT THER ...
