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 ...

DNA AND BIOSEQUENCES ARE BEING DETERMINED FASTER THAN THEY CAN BE COMPARED AND ANALYZED. PRESENT TECHNIQUES FOR RIGOROUSLY SEARCHING A LARGE DATABASE ARE COSTLY AND TIME CONSUMING. UNDER ALL PLAUSIBLE GROWTH PROJECTIONS, THE PROBLEM WILL SOON BECOME OVERWHELMING. A CUSTOM, VERY LARGE SCALE INTEGRATED CIRCUIT THAT COULD BE USED FOR HIGH SPEED COMPARISON, ANALYSIS, AND INTERPRETATION OF DNA AND PROT ...

THE GOAL IS AN INTERACTIVE COMPUTER PROGRAM TO FACILITATE NEEDS ASSESSMENT, DECISION- MAKING, GOAL SETTING, AND TRACKING ACROSS SERVICE PROVIDERS FOR MEETING THE NEEDS OF DISABLED INDIVIDUALS. THE PROPOSED APPROACH IS A RULE-BASED EXPERT SYSTEM AND MAN- AGEMENT INFORMATION SYSTEM INCORPORATING RULES FOR MAKING DECISIONS IN AREAS IN- CLUDING EDUCATION, RESIDENTIAL LIVING, FINANCE, HEALTH, SOCIAL IN ...

BORON NEUTRON CAPTURE THERAPY (BNCT) HAS A CLEAR THEORETICALADVANTAGE OVER OTHER TECHNIQUES AS A METHOD OF DELIVERING CELL-KILLING RADIATION TO CANCEROUS TUMORS. COMPOUNDS CONTAINING THE ELEMENT BORON, SUCH AS BORONOPHENYLALANINE (BPA), CAN ALSO SELECTIVELY LOCALIZE IN SKIN CANCERS SUCH ASMALIGNANT MELANOMA. UPON IRRADIATION BY A THERMAL OR EPITHERMAL NEUTRON BEAM, THE COMPOUND PRODUCES LOCALIZED ...

THIS RESEARCH AIMS TO DEMONSTRATE THE UTILITY OF EMPLOYING NOVEL FIBER-OPTIC SENSORS FOR USE IN HIGH PRESSURE AND HIGH TEMPERATURE ENVIRONMENTS. THE PLANNED SENSOR DESIGN EMPLOYS A NOVEL "SURFACE COMPOSITE" CONTAINING SOL-GEL COATINGS AND IMMOBILIZED FLUORESCENT ORGANIC COMPOUNDS. THE FIRST GOAL IS TO CHARACTERIZE AND DISCOVER WHAT FACTORS GOVERN THE ANALYTICAL FIGURES OF MERIT. TWO SPECIFIC SENSO ...

THIS RESEARCH PROJECT ADDRESSES THE DEMONSTRATION OF EPITAXIAL GROWTH, BY LASER ABLATION IN AN ULTRAHIGH VACUUM SYSTEM, OF HIGH QUALITY, WIDE-BANDGAP SEMICONDUCTOR FILMS ONTO HEATED SINGLE-CRYSTAL SILICON SUBSTRATES, FOLLOWED BY CHEMICAL VAPOR DEPOSITION (CVD) EPITAXIAL GROWTH OF SILICON ONTO THE WIDE-BANDGAP SEMICONDUCTOR. ON THE BASIS OF RECENT REPORTS OF SUCCESSFUL EPITAXIAL GROWTH OF CUBIC BOR ...

IN THE PHASE I PROJECT, THE FEASIBILITY OF DEVELOPING A SUPERIOR JOINING TECHNOLOGY FOR GRAPHITE AND CARBON-CARBON (C-C) COMPOSITES IS BEING INVESTIGATED. A NOVEL TECHNOLOGY,LOW TEMPERATURE ARC VAPOR DEPOSITION (LTAVD), IS BEING USED TO EFFECT THE JOINING OF GRAPHITE AND CARBON-CARBON COMPOSITES TO SIMILAR AND DISSIMILAR MATERIALS. TO OBTAIN STRONG JOINTS THAT ARE RESISTANT TO THERMAL CYCLING, MET ...
