WE PROPOSE TO INVESTIGATE VARIOUS CONTROL METHODS BY WHICH THE POWER FACTOR OF AN INDUCTION GENERATOR CAN BE REGULATED TO ACHIEVE ENCHANCED POWER CONVERSION EFFICIENCY. IN PARTICULAR, THIS STUDY WILL FOCUS UPON VARIABLE GENERATOR TERMINAL VOLTAGE CONTROL TO ACCOMPLISH THESE GOALS. VARIOUSCONTROL STRATEGIES WILL BE DEVELOPED IN ORDER TO IDENTIFY THE MOST COST-EFFECTIVE AND RELIABLE METHODS FOR TEST ...

THIS PROPOSAL FOR RESEARCH ADDRESSES THE NEED FOR NEW, HIGH-TEMPERATURE MATERIALS OF UNUSUAL STRUCTURAL AND PHYSICAL PROPERTIES. THE CHEMICAL STABILITY AND THE TENDENCY FOR EUTECTIC SOLIDIFICATION WOULD BE EXPLORED FOR SPECIFIC PERIODIC GROUP III AND IV METAL OXIDE-METAL NITRIDESYSTEMS. TO DO THIS, BLENDED OXIDE-NITRIDE POWDERS WOULD BEPRESSED INTO PELLETS, HEATED ON W, MO, OR TA STRIP HEATERS TO ...

THE PROJECT WILL INVOLVE ADAPTATION AND VALIDATION OF NOISE SIGNAL ANALYSIS FOR MONITORING OF OPERABILITY OF THE PROCESSSENSORS IN NUCLEAR POWER PLANTS. THE PROJECT WILL FOCUS ON DEVELOPING MICROCOMPUTER-BASED ALGORITHMS AND PROCEDURES FORCONTINUOUS, UNATTENDED MONITORING OF SENSORS AS THE PROCESS IS OPERATING. THE DISTINCTION BETWEEN SENSOR SYSTEM DEGRADATION AND PROCESS TRANSIENTS WILL BE PERFOR ...

THE ON-LINE DETECTION OF ENTRAPPED AIR VOIDS IN LIQUID-FILLED SENSING LINES WILL BE INVESTIGATED. IN NUCLEAR PLANTS THE SENSING LINES USED FOR MEASUREMENT OF FEEDWATER FLOWRATE AND REACTOR COOLANT LEVEL ARE OFTEN SEVERAL HUNDERED FEET IN LENGTH. THE PROBLEM ASSOCIATED WITH THE PRESENCE OF ENTRAPPED AIR CAN MANIFEST ITSELF AS EITHER A STATIC OR DYNAMIC OFFSET ERROR IN THE PROCESS PARAMETER MEASUREM ...

THE MONITORING OF ACIDIC DRY DEPOSITION HAS POSED SIGNIFICANT LOGISTICAL AND TECHNICAL PROBLEMS WHICH MUST BE OVERCOME AS PART OF OUR NATIONAL EFFORT TO ACCURATELY CHARACTERIZE AND UNDERSTAND ACID PRECIPITATION PATTERNS. THE SAMPLING EQUIPMENT IN WIDESPREAD USE TODAY HAS AS ITS TECHNOLOGICAL BASIS MANY FEATURES OF A 50-YEAR-OLD RAINFALL COLLECTOR, MODIFIED TO INCLUDE DRY SAMPLE COLLECTION. A SAMPL ...

40837 November 13, 1996 TomoSeis, Inc. Crosswell Seismic Imaging holds great promise for imaging the region between existing oil wells to incrementally increase the recovery of the 368 billion barrels of oil still in the ground (of the 500 billion barrels of original oil in place in the U.S.). To make crosswell data acquisition cost effective, surveys mu ...

THE RECENTLY DEVELOPED NOVIX COMPUTER USES THE LANGUAGE FORTH AS ITS NATIVE ASSEMBLY CODE THEREBY OFFERING THE FLEXIBILITY OF HIGH LEVEL LANGUAGE PROGRAMMING WITH ASSEMBLYLANGUAGE EXECUTION SPEED. THE RESULT IS A HARDWARE/SOFTWAREPERFORMANCE COMBINATION THAT CAN ONLY BE SURPASSED BY COMPLEX AND EXPENSIVE PARALLEL PROCESSING SYSTEMS. THE PRIMARY OBJECTIVE OF THE PROPOSED WORK IS TO RESEARCH AND DEV ...

GAS TRANSMISSION PIPELINES REQUIRE NATURAL GAS DELIVERED TO THEM TO MEET A HYDROCARBON (HC) DEWPOINT SPECIFICATION IN ORDER THAT THE HC LIQUIDS ARE NOT DROPPED OUT IN THE LINE DURING TRANSMISSION. SIMILAR SPECIFICATIONS ARE IMPOSED BY PLANT OPERATORS ON THE FUEL GAS THAT IS CONSUMED BY THEIR MACHINERY. A MARKET EXISTS FOR AN ECONOMICAL AMMONIA (NH3) ABSORPTION UNIT TO REPLACE COMPRESSION UNITS U ...
