A novel coating technology is proposed for increased wear and improved li fe and reliability of commutator bars in electrical sliding devices found in manned and unmanned underwater vehlilles. Diamond-Like Nanocomposite (DLN) coatings represent a famil Of thiWrfilms that bxhibit unique combinations of technologically interesting properties including high adhesion to virtually any substrate (inclu ...

DURING DEVELOPMENT OF COMPLEX, EMBEDDED SYSTEMS QUANTITATIVE TRADEOFFS OF RELIABILITY AND TIMING PERFORMANCE ARE OFTEN NOT CONSIDERED. DEGRADED PERFORMANCE IN ONE OR BOTH OF THESE AREAS CAN RESULT. AN INTEGRATED RELIABILITY AND TIMING ANALYSIS TOOL WILL PROVIDE THE CAPABILITY FOR SIMULTANEOUSLY ASSESSING SYSTEM DESIGNS FOR BOTH CHARACTERISTICS. BY BASING THE TOOL ON AN ICONIC DESIGN REPRESENTATION ...

A FEASIBILITY STUDY OF IMPROVING DECOY PENETRATION AID (PENAID) PERFORMANCE BY SUPPLYING MEANS TO 1) ALLOW FOR DUAL CENTER OF GRAVITY (CG) LOCATION, THEREBY ENABLING INDEPENDENT FULFILLMENT OF IMPULSE BALANCING AND REENTRY STABILITY REQUIREMENTS; AND/OR 2) COUNTERACT DECOY CONING BY SENSING ITS PRESENCE, AND CORRECTING THE ANGULAR MOMENTUM OF THE DECOY TO ELIMINATE CONING.

THE PROPOSED RESEARCH AIMS TO EMPLOY A RECENTLY PROVEN GENERALIZATION OF HERBRAND'S THEOREM TO AUTOMATIC THEOREM PROVING (ATP). THE GENERALIZATION, WHICH WAS PROVEN BY THE PRINCIPLE INVESTIGATOR, CHARACTERIZES PROVABILITY IN THE NORMALIZABLE FRAGMENT OF SET THEORY IN TERMS OF PROVABILITY IN PROPOSITIONAL LOGIC. THIS RESULT WILL BE APPLIED TO UTILIZE FINITE MODELS WHICH WILL PROVIDE SEMANTIC GUIDAN ...

CONAX HAS EXTENDED THE EXPERIENCE GAINED IN 14 YEARS OF ENGINEERING AND MANUFACTURING ELECTRICAL PENETRATORS TO SEALING DEVICES FOR FIBER OPTICS. FIBER OPTIC PENETRATORS WITH A TOTAL OPTICAL LOSS OF 0.3 DB AT 10,000 PSI HAVE BEEN DEMONSTRATED. AN INNOVATIVE USE OF COMPRESSIVE SEALING IS PROPOSED TO DEVELOP A PENETRATOR FOR SINGLE MODE FIBER WHICH IS MORE RUGGED AND HAS A WIDER OPERATING TEMPERATUR ...

THE LONG RANGE SCIENTIFIC GOALS OF THIS RESEARCH ARE TO INCREASE UNDERSTANDING OF THE CORRELATION OF MOLECULAR STRUCTURE WITH PHYSICAL PROPERTIES OF FERROELECTRIC LIQUID CRYSTAL (FLC) PHASES, AND TO TEST STRATEGIES FOR DESIGN OF NEW MATERIALS. THE PRACTICAL GOAL IS THE INVENTION OF NEW FLC MATERIALS WITH PROPERTIES SUITED FOR INCORPORATION INTO COMMERCIAL FLC SHUTTERS AND LARGE-AREA MATRIX DISPLAY ...

THE PROPOSED WORK AIMS TO DEVELOP NOVEL, HIGH PERFORMANCE SPATIAL LIGHT MODULATORS (SLM) MADE FROM ARRAYS OF FERROELECTRIC LIQUID CRYSTAL (FLC) LIGHT VALVES. THE FLC TECHNOLOGY ALLOWS SIMPLE, ECONOMICAL FABRICATION OF SLMS WITH A LARGE NUMBER OF ELEMENTS THAT CAN BE EASILY ADDRESSED EITHER ELECTRONICALLY OR OPTICALLY. PERFORMANCE FEATURES INCLUDE SUBMICROSECOND WRITE TIMES, HIGH OPTICAL THROUGHPUT ...

THE PROPOSED PROJECT AIMS TO DEVELOP A 1 X 2 ELECTRO-OPTIC SWITCH FOR USE WITH MULTIMODE OPTICAL FIBERS. BY EMPLOYING LIGHT VALVES HAVING FERROELECTRIC LIQUID CRYSTALS AS THE ELECTRO-OPTIC MEDIUM, THE DEVICES TO BE DEVELOPED WOULD EXHIBIT SWITCHING TIMES AT OR BELOW 1 MICROSECOND. THE DEVICES WOULD BE SMALL IN SIZE, CONSUME LITTLE ELECTRICAL POWER AND WOULD COMPLETELY SWITCH UNPOLARIZED LIGHT WHIL ...
