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 ...

MODERN COMPUTATION TECHNIQUES SUCH AS PARALLEL PROCESSING ARE WELL-SUITED FOR THE SOLUTION OF SUCH PROBLEMS AS THE SIMULTANEOUS GLOBAL EXTREMIZATION OF MULTIPLE VARIABLES IN A COMPLEX, NONLINEAR, PROBABILISTIC STATE SPACE. HOWEVER, THE USE OF THESE TECHNIQUES TO SOLVE A GIVEN PROBLEM REQUIRES THAT IT FIRST BE FORMULATED IN THESE TERMS. CURRENTLY, THREAT-AVOIDANCE MISSION PLANNING IS APPROACHED AS ...

MERCURY IS A HIGHLY TOXIC MATERIAL THAT OCCURS IN BOTH ORGANIC AND INORGANIC FORMS. BECAUSE OF ITS WIDESPREAD INDUSTRIAL USE THE WHOLE POPULATION IS EXPOSED TO MERCURY COMPOUNDS EVERYDAY. THERE IS A NEED FOR A FAST, EASY TO USE, INEXPENSIVE, SENSITIVE METHOD FOR THE DETECTION OF MERCURY TO REDUCE THE RISK OF CHRONIC EXPOSURE. OUR OBJECTIVE IS TO DEVELOP A NEW TECHNIQUE FOR THE SELECTIVE DETECTION ...

A FUNDAMENTAL PROBLEM IN AUTOMATIC TARGET RECOGNITION (ATR) IS THE OVERWHELMING AMOUNT OF SENSOR DATA WHICH MUST BE PROCESSED. MANY ADVANCED ATR ALGORITHMS WHICH REDUCE THE FALSE ALARM RATE CANNOT BE EXECUTED IN REAL TIME DUE TO COMPUTATIONAL COMPLEXITY. THIS LIMITS OVERALL SYSTEM PERFORMANCE. IN ATR, THE FEATURES THAT MUST BE RESOLVED ARE LOCALIZED WITHIN THE FIELD-OF-VIEW (FOV) OF THE SENSOR. UN ...

A METHOD OF CONVENIENTLY ADOPTING EXISTING SCENARIO LAYDOWNS TO A FORM COMPATIBLE WITH EXISTING MULTISPECTRAL SIMULATOR WILL ALLOW FACILITIES SUCH AS THE CECOM CENTER FOR EW/RSTA TO QUICKLY AND ECONOMICALLY CONFIGURE TEST SCENARIOS. NUMEROUS "BLESSED" MULTISPECTRAL LAYDOWNS EXIST THAT COULD BE IMPLEMENTED INTO SIMULATOR TESTING METHODOLOGIES WITH A MULTISPECTRAL INTERFACE. A COMPLEMENTARY METHOD F ...

AN ATTENTION MECHANISM CAN INFLUENCE SYSTEM BEHAVIOR AND PERFORMANCE ONLY TO THE EXTENT IN WHICH SYSTEM RESOURCES ARE ALLOCATABLE. A KEY VISUAL SYSTEM RESOURCE IS ACUITY, AND YET THIS RESOURCE IS FIXED IN CONVENTIONAL UNIFORM ACUITY MACHINE VISION. FEATURES TO BE RESOLVED BY ACTIVE VISION ARE TYPICALLY LOCALIZED WITHIN THE FOV. UNIFORM SAMPLING WITHIN THE FOV IS THUS INAPPROPRIATE; REGIONS WITH LI ...
