RADIO RELAYS INSTALLED ON ELEVATED PLATFORMS SUCH AS KITES AND BALLOONS CAN EXTEND LINE-OF-SIGHT VHF AND UHF COMMUNICATIOS RANGE BEYOND THE HORIZON. THESE RELAYS MUST BE LIGHTWEIGHT, OPERATE FOR SEVERAL HOURS ON SELF-CONTAINED BATTERIES, AND, BECAUSE THEY ARE EXPENDABLE ITEMS, BE LOW COST. A REPEATER WILL BE DEVELOPED USING CURRENT LOW-COST TECHNOLOGY THAT WILL SIMULTANEOUSLY REPEAT THREE COMMUNIC ...

THIS PROPOSED PROGRAM WILL EXAMINE PARAMETRIC AND FUNCTIONAL TESTING REQUIREMENTS AND DEVELOP THE RATIONAL FOR COMPARING THE EFFECTIVENESS OF THE TWO. FUNCTIONAL TESTING ADDRESSES THE TOTAL WEAPON SYSTEM ABILITY TO MEET THE MISSION REQUIREMENTS RATHER THAN EVALUATING THE INDIVIDUAL SYSTEM PARAMETERS. PARAMETRIC TESTING MAY REQUIRE SERIAL TESTING THAT CAN BE TIME CONSUMING AND THUS VERY COSTLY. ALS ...

Many visually impaired people have difficulty learning mathematics. The lack of higher math skills limits educational and job opportunities for many visually impaired people since numerous professions are requiring more technical skills. The objective of the Screen Reader Architecture Math System (SRAMS) is to design, develop, and test a computer based system which uses successful screen reading ...

N/A

A NEW APPROACH TO ALKALI BATTERY DEVELOPMENT, WHICH CAN SATISFY THE DEMANDING HIGH RATE, HIGH SPECIFIC ENERGY SPACE MISSION REQUIREMENTS, IS PROPOSED. THE PROPOSED APPROACH OFFERS SPEPCIFIC ENERGY PERFORMANCE COMPARABLE TO THE BEST RECHARGEABLE LITHIUM BATTERY CHEMISTRIES CURRENTLY UNDER DEVELOPMENT, WITH SUBSTANTIAL INCREASES IN SPECIFIC POWER. THIS PROPOSAL DESCRIBES A PHASE I BATTERY CONCEPT FE ...

N/A

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

THE HUMAN RETROVIRUSES THAT HAVE BEEN EXTENSIVELY CHARACTERIZED (HTLV-I, HTLV-II, HIV-1, AND HIV-2) ALL HAVE ATROPISM FOR THE PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMC). SEROLOGICAL ASSAYS HAVE BEEN USED QUITE SUCCESSFULLY TO IDENTIFY PERSONS WITH PRIOR EXPOSURE TO THESE VIRUSES, BUT THEY FAIL TO DETERMINE A CURRENT INFECTION. VIRUS ISOLATION ASSAYS REQUIRE PROLONGED CO-CULTIVATION OF PATIENTS' PBM ...

MANY UTILITY AND INDUSTRY COAL-FIRED BOILERS HAVE ELECTROSTATIC PRECIPITATORS (ESPS) ALONE, WHICH ARE NOT CAPABLE OF REMOVING SO2. MANY OLDER ESPS WILL REQUIRE UPGRADING IN THE 1990S TO MEET MORE STRINGENT PARTICULATE STANDARDS. ETS, INC. HAS TESTED ITS PATENTED LIMESTONE EMISSION CONTROL (LEC) SYSTEM, DEMONSTRATING GREATER THAN 90% SO2 REMOVAL CAPABILITY. LECS CAN BE PLACED DOWNSTREAM OF ESPS. IT ...

DEVELOPMENT OF A PLAN AND ITS DEMONSTRATION IN PRODUCING MODERN DATABASE FOR RV TECHNOLOGIES IS PROPOSED BY USING CLOUD MICROPHYSICAL DATA SETS COLLECTED SINCE 1985 OVER THE NORTH AMERICAN CONTINENT AND U.S. ARMY KWAJALEIN ATOLL. THE PLAN INCLUDES THE USE OF AIRBORNE RADAR, MODELING, AND SATELLITE ADDITIONS TO THE PARTICLE SIZE DATA TO CORRELATE PARTICLE SIZE AND LIQUID WATER CONTENT OVER AN EXTEN ...
