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 ...

PHASE I WILL EXPLORE NOVEL WAYS TO APPLY IMPROVED TECHNIQUES USING THE IEEE/ DOD STANDARD VHSIC HARDWARE DESCRIPTION LANGUAGE (VHDL) TO INTEGRATED ENGINEERING METHODS. IN PARTICULAR, IT WILL ENABLE HARDWARE AND SOFTWARE ENGINEERS TO COLLABORATE SIMULTANEOUSLY DURING DEVELOPMENT OF PARALLEL COMPUTING SYSTEMS. SOME SHORTCOMINGS OF VHDL HAVE BEEN OVERCOME BY THE DARPA QUEST PROJECT WITH DISTRIBUTING ...

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 ...

SURPLUS OFFSHORE OIL PLATFORMS AND SIMILAR STRUCTURES HAVE POTENTIAL AS BASES FOR THE SUPPORT OF OFFSHORE AQUACULTURE OPERATIONS. ONE CONCEPT DEVELOPED AT NET SYSTEMS ENVISIONS A PLATFORM SURROUNDED BY, AND HELPING TO SUPPORT, A RINGSHAPED ARRANGEMENT OF FLOATING FISH PENS. HOWEVER, BEFORE SUCH STRUCTURES CAN BE INCORPORATED INTO AQUACULTURE SYSTEMS, WE NEED TO BE ABLE TO PREDICT THEIR RESPONSE TO ...

CONCURRENT ENGINEERING (CE) PROVIDES THE MEANS FOR SHORTENING PRODUCT DEVELOPMENT SCHEDULES, REDUCING ACQUISITION COST, AND IMPROVING PRODUCT QUALITY BY ENABLING SIMULTANEOUS, INTEGRATED, AND PARALLEL EFFORTS ON RESEARCH, DESIGN, DEVELOPMENT, MANUFACTURING, AND OTHER SUPPORT PROCESSES. THE PROPOSED PROJECT WILL DEMONSTRATE THE FEASBILITY OF INNOVATIVE COLLABORATION TECHNOLOGY FOR ELECTRONIC MANAGE ...

MICRO-SHORT WAVELENGTH CHEMICAL LASERS (SWCLS) ARE PROPOSED FOR PUMPING SOLID STATE LASERS. SWCLS ARE ABLE TO GENERATE HIGH POWER LEVEL CW BEAMS IN THE 450 TO 550 NM SPECTRAL RANGE WHICH HAVE GOOD OPTICAL QUALITY AND ARE CAPABLE OF PUMPING SOLID STATE LASERS AT HIGH AVERAGE POWER LEVELS. MICRO-SWCLS ARE COMPACT, LIGHT WEIGHT, REQUIRE NO EXTERNAL ELECTRICAL ENERGY, HAVE HIGH EFFICIENICES, AND IN HI ...

THE FLOW FIELD ABOUT POWERED LIFT VEHICLES CAN BECOME VERY COMPLEX DUE TO HIGH ANGLES OF ATTACK AND LIFTING JETS. IN ADDITION TO MODELING PROPULSION/AIRFRAME INTERACTIONS, THEREFORE, FLOW PREDICTION METHODS MUST TREAT THE PROBLEMS OF SEPARATION AND THE TRANSIENT EFFECTS OF PASSING VORTICAL STRUCTURES INTERACTING WITH THE AIRFRAME. ANALYTICAL METHODS, INC. (AMI) PROPOSES TO EXTEND ITS POWERED LIFT ...

A GROWING NEED EXISTS BY BOTH THE MILITARY AND INDUSTRY FOR A RAPID METHOD OF REMOTELY MEASURING THE THICKNESS OF THE ARCTIC SEA ICE COVER. WE PROPOSE TO DEVELOP AN ELECTROMAGNETIC INDUCTION SENSOR TO REMOTELY MEASURE SEA ICE THICKNESS FROM AN AIRCRAFT. THEORY SUGGESTS THIS TECHNIQUE HAS GOOD POTENTIAL. IN ORDER TO VERIFY THE THEORY , A COMPUTER ANALYSIS AND A BRIEF ARCTIC FIELD TEST WILL BE PERFO ...
