THE DIGITAL ACTIVE MATERIALS-PROCESSING PLATFORM EFFORT BE- ING PROPOSED HERE SEEKS TO DEVELOP AN ACTIVELY STABILIZD PLATFORM UPON WHICH MICRO-G MATERIALS PROCESSING EXPERIMENTSCAN BE PERFORMED IN SPACE. WITH THE SUC- CESSFUL COMPLETION OF THE TWO-STEP PHASE I WORKPLAN APPLIED TECHNOLOGY ASSOCIATES (ATA) HAS CLEARLY AND SUCCINTLY DEFINED THE PROBLEM OF PLATFORM ISOLATION IN SPACE AND HAS COMPLETEL ...

LIQUID PROPELLANT ATOMIZATION PLAYS A DOMINANT ROLE IN STABLE AND EFFICIENT OPERATION OF ROCKET THRUST CHAMBERS. DESPITE THE RECENT PROGRESS IN COMPUTATIONAL FLUID DYNAMICS (CFD) AND SPRAY COMBUSTION MODELLING TECHNIQUES, NOSATISFACTORY APPROACH HAS YET BEEN DEVELOPED FOR PROPELLANT ATOMIZATION MODELLING. THE MAJOR INNOVATIVE ELEMENT OF THIS PROPOSAL IS TO PREDICT THE DROPLET BREAKUP RATE AND AVER ...

A GROWING NATIONAL NEED EXISTS FOR THE DEVELOPMENT OF A COMPUTER WORK STATION TECHNOLOGY WHICH IS INTERACTIVE AND ASSISTS THE USER IN CONTROLLING THE ACCURACY OF MANUAL DATA ENTRY TASKS DURING DATA BASE PREPARATION AND DURING COMMUNICATION OVER LOCAL AREA NETWORKS. SUCH A TECHNOLOGY WOULD AFFECT INCREASING NUMBERS OF NASA EMPLOYEES AT ALL LEVELS AS COMPUTER TERMINALS BECOME WIDELY USED IN MANAGEME ...

IT IS DESIRABLE TO HAVE A MTHOD FOR EFFICIENT, COST EFFEC- TIVE, AND SIMULTANEOUS REMOVAL OF PB(II), AG(I), CD(II) AND HG(II) FROM POTABLE WATER TO LEVELS WELL BELOW THEIR EPA LIMITS. SUCH A METHOD COULD BE USED BY BOTH MUNICIPAL WATER WASTE TREATMENT PLALNTS. THE INTERACTION OF THE MACROCYCLE TETRAAZA-18CROWN WITH THE METALS OF INTEREST IS OF SUFFI- CIENT STRENGTH AND SELECTIVITY TO REMOVE THE ME ...

CARBON MONOXIDE IS A COLORLESS, ODORLESS, POISONOUS GAS PRO-DUCED BY THE INCOMPLETE COMBUSITON OF HYDROCARBON FUELS. IT IS A SIGNIFICANT OUTDOOR AND INDOOR AIR POLLUTANT. AUTOMO ARE THE MJOR SOURCE OF OUTDOOR CARBON MONOXIDE, AND IT IS EMITTED AT THE HIGHEST RATE DURING THE FIRST FEW MINUTES WHEN THE CATALYTIC CONVERTER IS NOT ACTIVE. MAJOR SOURCES OF INDOOR POLLUTION ARE APPLIANCES AND CIGARETTES ...

THE NEXT GENERATION OF SPACEFLIGHT VEHICLES, SUCH AS THE AFECURRENTLY BEING DESIGNED, WILL REQUIRE MORE PRECISE PREDICTIONS OF THE VEHICLE AERODYNAMICS IN THE TRANSITIONAL FLOW REGIME THAN WAS ACHIEVED WITH THE SPACE TRANSPORTATION SYSTEM. THIS IS NECESSITATED BY THE NEED TO REDUCE ONBOARD GUIDANCE AND CONTROL CONSUMABLES IN FAVOR OF INCREASED PAYLOAD. THE OBJECTIVES OF THE PHASE I STUDY IS TO REV ...

AS THE ORBITAL MANEUVERING VEHICLE OR ASTRONAUTS SEATED IN THE MAN MANEUVERING UNIT MOVE EXTERNALLY ABOUT THE SPACE STATION TO PERFORM ASSEMBLY, MAINTENANCE, PAYLOAD SERVICING,AND OTHER EVA ACTIVITIES, THEIR RCS MICRO-THRUSTER PLUMES MAY IMPINGE ON VARIOUS STRUCTURES/PAYLOADS CREATING LOCALLY SEVERE ENVIRONMENTS AND SURFACE CONTAMINATION. THE OPPORTUNITIES FOR POTENTIALLY SEVERE IMPINGEMENT AND CO ...

ANY VERY HIGH LEVEL LANGUAGE (VHLL) FOR STRATEGIC DEFENSE REQUIRES A COMPILER. NEW META COMPILERS USING ADVANCED ARTIFICIAL INTELLIGENCE METHODS ARE BEING STUDIED SO THAT EVENTUAL VHLL APPLICATION SOFTWARE CAN BE EFFECTIVELY PORTED TO THE SEVERAL GROUND-BASED/SATELLITE-BASED MACHINES. TO DO SO REQUIRES A META COMPILER THAT CAN COMPILE CODE TO DIVERSE ARCHITECTURES. RESEARCH WITH META COMPILERS DEM ...

POLYMERIC OR CERAMIC INSULATORS CONVENTIONALLY ARE BEING USED IN HIGH VOLTAGE PULSED SYSTEMS. NEW APPROACHES ARE NEEDED THAT WOULD REDUCE INSULATORS RING THICKNESSES AND INCREASE CORRESPONDING GRADING RINGS FLASHOVER VOLTAGE. SUCH AN APPROACH WOULD POSSESS IN COMPARISON TO CONVENTIONAL INSULATORS: HIGHER SURFACE FLASHOVER FIELD STRENGTH; SMALLER PHYSICAL DIMENSIONS FOR EQUIVALENT VOLTAGE HOLDOFF; ...

THE DEVELOPMENT OF HIGH POWER, LOW IMPEDANCE, LIGHTWEIGHT ENERGY STORAGE TRANSMISSION LINES FOR PULSE-POWER APPLICATIONS IS CRUCIAL FORSMALLER, LIGHTWEIGHT, SPACE-BASED, PULSE-POWER SYSTEMS. DEVELOPMENT OF HIGH DIELECTRIC ENERGY STORAGE LINE TECHNOLOGY WOULD GREATLY REDUCETHE SIZE, WEIGHT, AND COMPLEXITY OF PULSE POWER SYSTEMS UTILIZING THESE TYPES OF COMPONENTS. EFFICIENT TRANSPORT OF 400KV, 100K ...
