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 ...

THE MILLIMETER WAVE COMBAT IDENTIFICATION DEVICE IS A PASSIVE (NON-EMITTING) BEACON WHICH IS A LOW-COST, COMBAT RUGGED DEVICE FOR THE POSITIVE IDENTIFICATION OF FRIENDLY GROUND VEHICLES, IN TIGHT QUARTERED, OBSCURE BATTLEFIELD ENGAGEMENTS AND CONDITIONS. THE PASSIVE IFF BEACON IS AUTONOMOUS, EXCEPT FOR THE MANUAL/TAMPER DEACTIVATION FEATURE. OTHER THAN ACTIVATION, THE UNIT REQUIRES NO CREW ATTENDA ...

WE PROPOSE A NOVEL TECHNOLOGY FOR A REAL-TIME X-RAY IMAGER. THE PROPOSED TECHNOLOGY CAN BE ADAPTED TO SPECIFIC MEDICAL OR INDUSTRIAL APPLICATIONS WHICH MAY HAVE DIFFERENT REQUIREDCHARACTERISTICS. THE SPATIAL RESOLUTION CAN BE IN THE RANGEOF 5 TO 20 LINE PAIRS PER MM. A SINGLE UNIT HAS AN ACTIVE IMAGING AREA OF 10 CM X 10 CM. BECAUSE THERE IS ESSENTIALLYNO DEAD SPACE AROUND THE EDGE OF A UNIT, SEVE ...

AN ORTHOGONAL LOCALIZATION AND ORIENTATION SYSTEMS (OLOS) THAT UTILIZE A COMBINATION OF MAGNETIC, GRAVITATIONAL AND ACOUSTIC SENSORS WILL BE INVESTIGATED. CURRENTLY, THE BEST APPROACH SEEMS TO BE A COMBINATION OF MAGNETICS TO PROVIDE HORIZONTAL DIRECTION, GRAVITY TO PROVIDE TILT, AND ACOUSTICS TO PROVIDE POSITION. POSITION ACCURACY SHOULD BE < 1 ARC MINUTE, AND RESPONSE TIME < 20 MSEC. OTHER APPRO ...

THIS PROPOSED RESEARCH IS INVOLVED IN DESIGNING SYSTEMS CAPABLE OF AUTOMATIC TARGET RECOGNITION (ATR) IN HOSTILE ENVIRONMENTS. SPECIAL NOTE IS MADE OF THE UNIQUE ASPECTS OF ATR IN RELATIONTO THE GENERAL PROBLEM OF OBJECT RECOGNITION AS STUDIED IN PATTERN RECOGNTION AND COMPUTER VISION. RESEARCH IS THEN PROPOSED THAT INVOLVESTHE DEVELOPMENT OF AN ATR TECHNIQUE FOR USE IN GROUND-TO-GROUND OPERATION ...

THERE IS MOUNTING EVIDENCE THAT OUR SECONDARY MATHEMATICS AND SCIENCE EDUCATIONAL DELIVERY SYSTEM IS IN A STATE OF CRISIS. THE PROBLEMS ARE PROFOUND AND SEEMINGLY ENDLESS. WHILE IT IS AXIOMATIC THAT OUR EDUCATIONAL INFRASTRUCTURE NEEDS TO BE REBUILT, IT IS ALSO SELF-EVIDENT THAT THE ISSUES OF COST, CURRICULUM INSERTION, AND TEACHER ACCEPTANCE MUST BE SIMULTANEOUSLY ADDRESSED. THE LEADING CANDIDATE ...
