A COMPUTER MODELING APPROACH IS PROPOSED TO STUDY THE EFFECT OF FRICTION OR TRACTION CHARACTERISTICS OF LUBRICANTS ON THE STABILITY OF BEARING ELEMENTS AND THE OVERALL LIFE OF A ROLLING BEARING. THE PROPOSED APPROACH CONSISTS OF USING AN EXISTING BEARING DYNAMICS COMPUTER PROGRAM TO SIMULATE THE DYNAMIC PERFORMANCE OF THE BEARING AS A FUNCTION OF THE FRICTION BEHAVIOR AT THE ROLLING ELEMENT/RACE, ...

THE NUMBER OF STABLE, INEXPENSIVE ANODE MATERIALS AVAILABLE FOR THE ELECTROSYNTHESIS OF CHEMICALS IS QUITE LIMITED. A SERIES OF HIGH SURFACE AREA CARBONS AND GRAPHITES ARE PROPOSED AS NEW ANODE MATERIALS FOR A VARIETY OF ELECTROCHEMICAL PROCESSES. THESE MATERIALS HAVE BEEN FOUND TO BE STABLE IN STRONGLY ACIDIC MEDIA AT HIGH OXIDATION POTENTIALS. THE EFFECTIVENESS OF THE HIGH SURFACE ELECTRODES VS. ...

THE FEASIBILITY OF DEVELOPING AN EXTREME STABLE, SPECTRALLY NARROW (150 MEZ), HIGH REPETITION RATE (30 KHZ) TUNABLE DYE LASER OSCILLATING IN A SINGLE LONGITUDINAL MODE OVER THE ENTIRE RANGE OF THE DYE IS EXAMINED. THE EXTREME SHORT CAVITY (5 CM), LONGITUDINAL PUMPED GRAZING INCIDENCE DYE LASER DESIGN OF THE PROPOSED SCHEME PROVIDES MANY DISTINCT ADVANTAGES. THE SHORT CAVITY DESIGN NOT ONLY SUPPORT ...

THE PROPOSED RESEARCH RELATES TO THE REDUCTION IN NUMBER OF ELEMENTS AND INCREASE OF PERFORMANCE OF OPTICAL SYSTEMS. BY ADDING A SPATIAL INDEX OF REFRACTION DISTRIBUTION (GRADIENT-INDEX), THE NUMBER OF ELEMENTS COULD BE SUBSTANTIALLY REDUCED. IN THE PROPOSED RESEARCH, DESIGN ANALYSIS WILL BE CONDUCTED TO DETERMINE THE OPTIMUM PROFILESFOR HIGH QUALITY LENS SYSTEMS. PHASE II RESEARCH WILL STUDYTHE P ...

THE INTEGRATION OF OPTICAL CAM SYSTEM PARAMETERS DIRECTLY INTO OPTICAL CAD PROGRAMS IS EXAMINED. WITH OPTICAL CAM SYSTEMS EMERGING, IT IS IMPORTANT TO BE ABLE TO REPRESENT THE FAMILY OF SURFACES WHICH CAN BE PRODUCED ON THE OPTICAL CAM IN AN OPTICAL CAD PROGRAM. MATHEMATICAL MODELS WILL BE DERIVED WHICH REPRESENT THE POSSIBLE OPTICAL SURFACES IN TERMS OF A CAM SYSTEM'S OPERATING PARAMETERS. SENSIT ...

THE VERY POLITICALLY SENSITIVE NATURE OF NUCLEAR WARFARE WOULD PRESUPPOSE THAT THE ABILITY OF THE COMMANDER TO PLAN FOR THE USE OF WEAPONS OF THIS TYPE WOULD CREATE THE NEED FOR A METHOD WHICH WOULD BE AS FOOL-PROOF AS POSSIBLE. EARLY WEAPONS WERE DESIGNATED STRATEGIC WEAPONS WHILE LATER DEVELOPED WEAPONS WERE CALLED TACTICAL. IT WAS WITH THE EVOLUTION TO TACTICAL WEAPONS THAT EXTENSIVE POSITIVE C ...

CELL FUSION PROVIDES BIOTECHNOLOGISTS WITH THE ABILITY TO GENERATE UNIQUE CELL TYPES BY MIXING THE GENETIC MATERIAL OFTWO PARENT CELLS. THE GENERATION OF IMMORTAL ANTIBODY PRODUCTING HYBRIDOMAS BY FUSING ANTIBODY PRODUCING SPLEEN CELLS WITH MYELOMA CELLS PROVIDES AN EXAMPLE OF THE UTILITY OF CELL FUSION TECHNOLOGY. HOWEVER, THE WIDELY USED CHEMICAL FUSION PROCEDURES, BASED ON POLYETHYLENEGLYCOL (P ...

A MAJOR CONSTRAINT UPON THE CULTURE OF EDIBLE MARINE ORGAN- ISMS ON A COMMERCIAL SCALE IN MOST COASTAL STATES IS THE LACK OF AVAILABILITY OF SUITABLE CULTURE AREAS. MANY ECOLOGICALLY FAVORABLE AREAS OF THE COASTLINE ARE CLOSED TO AQUA CULTURE AS A RESULT OF ZONING RESTRICTIONS, LOCAL ORDINANCESAND SOCIAL RESISTANCE. AS A RESULT, THE ONLY RECOURSE FOR MANY AQUACULTURE ENTERPRISES MAY BE TO DEVELOP ...

THIS PROPOSAL PRESENTS A RESEARCH PLAN FOR THE MEASUREMENT OF SURFACE DEFECTS ON EITHER HARD DISK MEDIA OR HARD DISK SUBSTRATES. THESE DEFECTS CAN EFFECT THE PERFORMANCE OF A COMPUTER DISK AS THE HEAD TRACKS OVER THE SURFACE. THE PROPOSED RESEARCH PROGRAM IS TO MEASURE SURFACE DEFECTS ON COMPUTER HARD DISKS USING NON-CONTACT OPTICAL SCANNING INTERFEROMETRY. THE EFFECTS OF SIGNAL TO NOISE RATIO, SI ...

IMPROVED PREDICTIONS OF PETROLEUM RESERVOIR PERFORMANCE ARE NEEDED TO REDUCE THE RISKS ASSOCIATED WITH FIELD SCALE MISCIBLE FLOODING. A MAJOR SHORTCOMING OF CURRENT PREDICTION TECHNIQUES IS THE FAILURE TO ACCURATELY MODEL THE EFFECTS OF MOBILITY RATIO AND VISCOUS FINGERING ON VOLUMETRIC SWEEP AND DISPLACEMENT EFFICIENCY. THE PROPOSED RESEARCH WILL DEVELOP IMPROVED NUMERICAL TECHNIQUES FOR THIS PRO ...
