THIS RESEARCH PROJECT WILL DEMONSTRATE THE TECHNICAL AND ECONOMIC FEASIBILITY OF A MAGNETIC SEPARATOR FOR OPERATION ON PULVERIZED COAL. A THEORETICAL COMPARISON OF THE SEPARATOR WITH WORK PUBLISHED ON OPEN GRADIENT MAGNETIC SEPARATION BY THE OAK RIDGE NATIONAL LABORATORY INDICATES THAT THE SEPARATOR WILL HAVE HIGH LEVELS OF ASH CLEANING. THIS IS BECAUSE OF ITS COUNTERCURRENT PRINCIPLE OF OPERATION ...

WE PROPOSE THE DEVELOPMENT OF GLOBAL SPECTRAL NUMERICAL WEATHER PREDICTION (NWP) MODELS SPECIALLY DESIGNED TO TAKE ADVANTAGE OF MULTIPROCESSING COMPUTERS. SEVERAL CANDIDATE ALGORITHMS WILL BE DESIGNED AND ANALYZED. THE BEST DESIGNS WILL BE CODED AND TESTED IN A SIMULATED MULTIPROCESSOR. THIS STUDY IS IMPORTANT BECAUSE OPERATIONAL NWP IS TIME CONSTRAINED AND LIMITED BY AVAILABLE COMPUTING POWER. FU ...

THERE IS A NEED FOR AN INEXPENSIVE, COMPACT, LOW MAINTENANCE SUB-PICOSECOND OPTICAL PULSE SOURCE TO DRIVE AN OPTICALLY SAMPLED AND TRIGGERED OSCILLOSCOPE. ADEQUATE LASER SOURCES PRESENTLY OCCUPY TEN SQUARE FEET AND REQUIRE REGULAR MAINTENANCE, 20 KW OF ELECTRICITY, AND COOLING WATER; AND THEY COMPRISE THE MAIN COST ITEM IN THE PICOSECOND OSCILLOSCOPE. THE NEW PULSED LASER UNDER DEVELOPMENT IN THIS ...

ONE OF THE MOST ACTIVE AND CHALLENGING FIELDS IN MOLECULAR BIOLOGY TODAY IS THE GENETIC STUDY OF EUKARYOTIC SYSTEMS. THE PRELIMINARY, BUT OFTEN RATE LIMITING, STEPS IN THIS AREA ARE THE DNA TRANSFER/HYBRIDIZATION TECHNOLOGIES ASSOCIATED WITH GENE MAPPING, AND THE SCREENING OF DNA LIBRARIES FOR GENE ISOLATION. THESE PROCEDURES USE RADIOLABELED HYBRIDIZATION TECHNIQUES AND AUTORADIOGRAPHY TO ACHIEVE ...

EVERY US LAUNCH SYSTEM DEVELOPED TO DATE HAS ASSUMED THE NEED FOR EXTREME RELIABILITY AND MAXIMUM OBTAINABLE PERFORMANCE IN THE PRIMARY COMPONENTS OF THE STRUCTURE AND PROPULSION SYSTEM. THIS APPROACH STRETCHES THE LIMITS OF AVAILABLE TECHNOLOGY, AND HAS REPEATEDLY RESULTED IN LAUNCH SYSTEMS WHICH CAN NOT PUT MATERIAL INTO EARTH ORBIT AT AN ACCEPTABLE COST. THE SPACE SYSTEM DESIGN COMMUNITY HAS DE ...

THE UNIQUE PROPERTIES OF DIAMOND MAKE IT ATTRACTIVE AS A MATERIAL FOR USE IN HIGH FREQUENCY, HIGH POWER, MILLIMETER MICROWAVE TUBES AND TRANSMISSION LINES. RECENT ADVANCES IN GYROTRONS AND FREE ELECTRON LASERS (FELS) AS POWER SOURCES, AND EXCELLENT PHYSICS RESULTS FROM THE T-10 TOKAMAK IN THE U.S.S.R. AND BIG-D AT GA TECHNOLOGIES IN THE U.S., HAVE HAD A MAJOR IMPACT ON THE FUSION PROGRAM. AN EXPER ...
