THE EFFICIENCY OF THE SCRUBBER ON THE HF HIGH ENERGY LASER WILL BE MEASURED UTILIZING FOURIER TRANSFORM INFRARED SPECTROSCOPY (FTIR). CONCENTRATIONS OF HF AND FLOWS WILL BE MEASURED BEFORE AND AFTER THE SCRUBBER, AND RECOMMENDATIONS MADE TO IMPROVE SCRUBBER EFFICIENCY, IF NECESSARY. AMBIENT AIR SAMPLING USING EITHER FTIR OR OTHER WET CHEMICAL METHOD WILL BE PERFORMED TO VALIDATE THE MODEL PREDICTI ...

FLUME TESTS OF THE SCOUR-RESISTANT PROPERTIES OF A COMPOSITE SCOURINHIBITING MATERIAL ARE PROPOSED. THE MATERIAL IS MADE FROM GRAVEL AND CLAY. BY FILLING THE PORE SPACES IN THE GRAVEL, THE CLAY PREVENTS TURBULENT FLUID BURSTS FROM PENETRATING THE GRAVEL AND "SUCKING OUT" UNDERLYING BED MATERIAL. THE SCOUR INHIBITOR REMAINS PLASTIC AND FORMS A GRADATIONAL MARGIN BETWEEN ANY RIGID STRUCTURE AND A MO ...

THE DEVELOPMENT OF A NEW GENERATION OF DURABLE, EASY TO USE POWER CONNECTORS FOR BATTLEFIELD USE IS PROPOSED. THE DESIGN OF THIS PRODUCT WILL TAKE ADVANTAGE OF THE DEVELOPMENT OF HIGH PERFORMANCE REINFORCED POLYMERS TO PROVIDE NON DENTING, AND NON CORRODING, HOUSINGS. RETENTION MECHANISMS WHICH ARE EASIER TO USE, AND MORE DURABLE THAN THREAD OR BAYONETTE DESIGNS WILL BE PART OF THE OBJECTIVE. CONT ...

DISCRETE ELEMENT X-RAY DETECTORS DEVELOPED FOR MEDICAL COMPUTER TOMOGRAPHY ARE RECENTLY BEING APPLIED AS A DETECTION MEDIUM FOR INDUSTRIAL X-RAY RADIOGRAPHY. THE DETECTORS ARE DESIGNED WITH A WIDE DYNAMIC RANGE TO ACCOMMODATE THE MULTIPLE PATH DATA COLLECTION NECESSARY FOR COMPUTED TOMOGRAPHY. IN THE STANDARD RADIOGRAPHIC INSPECTION MODE, THIS FEATURE ALLOWS THE EVALUATION OF A WIDE RANGE OF MATER ...

THE IMPORTANCE OF COUNTING NOBLE GAS ATOMS WITH ISOTOPIC SELECTIVITY STEMS FROM THE PRACTICAL FACT THAT THESE ATOMS CAN BE REMOVED FROM LARGE QUANTITITES OF MATERIALS, AND IF COUNTED INDIVIDUALLY, OFFER OPPORTUNITIES FOR PARTICLE PHYSICS, DATING, ENVIRONMENTAL, AND MEDICAL APPLICATIONS. RESONANCE IONIZATION SPECTROSCOPY (RIS), COMBINED WITH MASS SPECTROSCOPY, HAS LED TO A SYSTEM FOR COUNTING KR-81 ...

A SMALL, RUGGED, ANGULAR VELOCITY SENSOR HAS BEEN DEVELOPED RECENTLY BASED ON THE MAGNETOHYDRODYNAMIC (MHD) PHENOMENON. THE SENSOR IS APPROXIMATELY ON CUBIC INCH IN VOLUME AND HAS AN RMS NOISE LEVEL OF 10 -4 MILLIRADIANS IN THE 2 TO 2000 HZ. REGION. THE PROPOSED WORK WILL UTILIZE THIS RECENT TECHNOLOGY TO DEVELOP SENSORS TO MEASURE THE ANGULAR MOTION OF CANNON MUZZLES. EXISTING COMPUTER PROGRAMS C ...
