THE SCATTERING OF X-RAYS CAN BE USED TO IMAGE THE DENSITY OFANATOMICAL STRUCTURES UP TO SEVERAL CENTIMETERS DEEP IN THE HUMAN BODY. THIS RESEARCH DESCRIBES A TECHNIQUE OF USING COMPTOM SCATTERED X-RAYS IN AN IPSILATERAL (BACKSCATTER) GEOMETRY TO OBTAIN THREE-DIMENSIONAL DENSITY INFORMATION FORMAXILLODENTAL IMAGING. THE TECHNIQUE IS CALLED COMPTON SCATTER TOMOGRAPHY (CST). CURRENTLY, IN THIS ANATOM ...

LABOR SAVING TECHNIQUES ARE ESSENTIAL GIVEN THE CURRENT PRESSURE ON CLINICAL COST CONTAINMENT. SINCE BLOOD CLASSIFICATION AND SCREENING IS A NOTORIOUSLY LABOR INTENSIVE AREA OF THE CLINICAL LABORATORY, MANUFACTURERS HAVE CONCENTRATED ON DEVELOPING VARIOUS ABO/RH TYPING TECHNIQUES. FEW OF US RECOGNIZE THE SPECIALIZATION NEEDED IN PERFORMING SUCH TESTS, AND THE MINOR IMPACT THESE TESTS HAVE HAD IN T ...

THIS THREE PHASE PROJECT IS DESIGNED TO ASSIST DISABLED STUDENTS IN TRANSITION FROM SCHOOL TO WORK BY PROVIDING TWO NEW MICROCOMPUTER-BASED PROGRAMS TO REHILITATION SPECIALISTSIN THE WISCONSIN DIVISION OF VOCATIONAL REHABILITATION SPECIAL SERVICES UNIT WHICH ANNUALLY EVALUATES AND SCREENS OVER 700 YOUNG HANIDCAPPED PERSONS SEEKING TO LEAVE SCHOOL AND ENTER THE WORKPLACE. THESE PROGRAMS ARE DESIGNE ...

A NOVEL NON-CONTACT NON-INVASIVE INFRARED (IR) SENSOR IS PROPOSED FOR IN-SITU DIAGNOSTICS IN CVD REACTORS. DURING CVD PROCESSES, THE SUBSTRATES WILL BE HEATED. THE IR SENSOR TAKES THE ADVANTAGE OF THE HEATED SUBSTRATE AS THE SOURCES OF IR RADIATION. BY SENSING AND ANALYZING THE IR RADIATION FROM A SUBSTRATE, THE SUBSTRATE SURFACE CAN BE PROBED. MOREOVER, LOW TEMPERATURE SILICON EPITAXY HAS BEEN CH ...

LOW FLYING AIRCRAFT CANNOT BE DETECTED BY STANDARD RADAR BECAUSE OF INTERFERENCE FROM CLUTTER. THIS PROPOSAL DESCRIBES A COHERENT LASER RADAR SYSTEM APPROACH, CONSISTING OF 2 KM SPACED LASER RADAR SITES THAT SCAN THE SKY IN ELEVATION ANGLE, WHICH CAN DETECT AIRCRAFT BETWEEN THE HORIZON AND 300 METER ALTITUDE. EACH SITE WILL BE BATTERY POWERED AND INTERCONNECTED BY A FIBEROPTIC LOCAL AREA NETWORK T ...

THE UNIVERSE OF AVAILABLE TECHNOLOGIES WILL BE EVALUATED AGAINST REQUIREMENTS FOR A BRIGADE OR LOWER LEVEL DEVICE INTENDED TO PRINT MAP DATA. THE OBJECTIVES OF THE PROJECT WILL BE TO SELECT THE BEST TECHNOLOGY FOR A BRIGADE LEVEL HARD COPY DEVICE AND TO OUTLINE THE PHASE II PROGRAM STEPS NEEDED TO BRING THE PRODUCT TO FRUITION. THE PROPOSED PROGRAM WILL INCLUDE THREE STEPS. IN THE FIRST, WE WILL I ...

THE ELECTRICAL AND MATERIAL PROPERTIES OF HIGH TEMPERATURE SUPERCONDUCTING (HTSC) THIN FILMS HAVE IMPROVED DRAMATICALLYIN RECENT MONTHS. HOWEVER, A FABRICATION PROCESS CAPABLE OFPRODUCING JOSEPHSON JUNCTIONS IN FINITE YIELDS HAS YET TO BEDEVELOPED. SOME DEMONSTRATION DEVICES HAVE BEEN MADE WHICH INDICATE THAT THE 77 K NOISE LEVELS OF DC SQUIDS MADE FROM THALLIUM-BORIUM-CALCIUM-COPPER-OXIDE ARE LOW ...

THE USE OF PEROVSKITES SUCH AS BATIO3 AS THIN FILM FERROELECTRIC MATERIALS IN MICROELECTRONICS AND PHOTONICS HAS BEEN LIMITED BY MATERIALS PROCESSING AND COMPATIBILITY PROBLEMS. HIGH QUALITY FERROELECTRIC THIN FILMS HAVE NOT BEEN GROWN AT TEMPERATURES COMPATIBLE WITH STANDARD SI OR GAAS PROCESSING TECHNOLOGY. CONSIDERING THE SUPERB ELECTRICAL AND OPTICAL PROPERTIES OF THESE MATERIALS AS WELLAS THE ...
