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 ...

A COMMON DILEMMA IN ECOSYSTEM MODELING IS THE COMPLEXITY OF BIOLOGICAL SYSTEMS AND THE LACK OF SUFFICIENT DATA. TRADITIONAL MODELING APPROACHES REQUIRE QUANTITATIVE DATA AND DETAILED KNOWLEDGE OF THE ECOLOGICAL SYSTEM. ALTHOUGH SUCH DATA MAY BE AVAILABLE FOR SMALL CONTROLLED SYSTEMS SUCHAS THE LABORATORY MICROCOSM, IN MOST CASES SUFFICIENT INFORMATION IS NOT AVAILABLE FOR LARGE NATURAL SYSTEMS. QU ...

THE OBJECT OF THIS PROPOSED RESEARCH IS TO PRODUCE MORE RELIABLE ESTIMATES OF EXTREME WINDS IN THE UNITED STATES BY SEPARATELY ANALYZING WINDS DUE TO THUNDERSTORMS AND LARGE SCALE EXTRATROPICAL STORMS. THE PRESENT STATE OF THE ART METHODS FOR ESTIMATING DESIGN WIND SPEEDS IN NON-HURRICANE REGIONS OF THE UNITED STATES DO NOT DISTINGUISH BETWEEN WINDS ORIGINATING FROM THE LARGE SCALE EXTRATROPICAL P ...

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 ...

WE PROPOSE TO DEVELOP A THIN-FILM INTEGRATED CAPACITOR STRUCTURE THAT INCORPORATES AN INSULATOR WITH A VERY HIGH DIELECTRIC CONSTANT. THIS CAN HAVE IMPORTANT APPLICATION TOHIGH-DENSITY COMPUTER MEMORY CHIPS WITH ELEMENTS ON THE MICRON AND SUBMICRON SCALE. IN ITS RUTILE CRYSTALLINE FORM,TIO2 EXHIBITS A DIELECTRIC CONSTANT GREATER THAN 100, WHICH CORRESPONDS TO A CAPACITANCE OF I UF/CM(2) FOR A 100 ...

ENGINEERING APPLICATIONS OF LAYERED COMPOSITES OR LAMINATES ARE VERY IMPORTANT AND DIVERSE. INTERLAYER CRACKSOR DELAMINATIONS IS ONE OF THE MAJOR REASONS OF COMPOSITE STRUCTURAL FAILURE. DELAMINATIONS MAY CAUSE CONSIDERABLE DEGRADATION OF STIFFNESS AND STRENGTH OF COMPOSITE STRUCTURES. THIS PHENOMENON HAS RECEIVED CONSIDERABLE ATTENTION IN RECENT YEARS. BUT, TO ACHIEVE A DEEPER INSIGHT INTO THE PR ...
