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 ...

A SERIOUS LACK OF EFFICIENT COMPUTER AIDED DESIGN (CAD) PROCEDURES EXISTS FOR HIGH-PERFORMANCE MONOLITHIC MILLIMETER WAVE INTEGRATED CIRCUITS, THAT OPERATE BETWEEN 30 AND 100 GHZ. THIS IS DUE TO THE HIGH-FREQUENCY BEHAVIOR OF THE VARIOUS (PASSIVE) COMPONENTS AND HIGH SPEED INTERCONNECTORS OF THE SYSTEM, AS WELL AS TO THE ANISOTROPY OF THE SUBSTRATE. THIS BEHAVIOR IS NOT SIGNIFICANT AT LOWER FREQUE ...

RAPID INTENSE HEATING OF COMPOSITE LAMINATES DUE TO DIRECT ENERGY WEAPONS WILL INDUCE STRONG THERMAL GRADIENTS THAT IN TURN PRODUCE DYNAMIC STRESSES IN THE FORM OF WAVE MOTION. THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A MINDLIN PLATE FINITE ELEMENT PROGRAM FOR ANALYSIS OF THE DYNAMIC BEHAVIOR IN A COMPOSITE LAMINATE SUBJECTED TO COMBINED THERMAL/SHOCK AND SIMULATED IN-FLIGHT AERODYNAMIC LOADIN ...

INADEQUATE STARTER FEEDS SEVERELY HOLD BACK NEW AQUACULTURE ENTERPRISES SUCH AS PRESENT ATTEMPTS TO RAISE FISHES WHOSE LARVAE DEVELOP FROM SMALL EGGS AND HAVE VERY "DIFFICULT" FOOD REQUIREMENTS. INERT LARVAL FEEDS HAVE NOT SUCCESSFULLYELIMINATED THE STRICT DEPENDENCY ON NATURAL FORAGE DURING THE CRITICAL POST-LARVAL STAGE AFTER YOLK ABSORPTION AND BEFORE THE DEVELOPMENT OF A DIGESTIVE SYSTEM WITH ...
