AN ELECTROCHEMICAL INSTRUMENTATION SYSTEM WILL BE DESIGNED AND CONSTRUCTED TO DETERMINE ON COMMAND PLANT WATER STATUS BY MEANS OF CYCLIC VOLTAMMETRY AND/OR COULOSTATICS. THE APPROACH IS BASED ON THE CHANGE IN ELECTROCHEMICAL STATUS OF THE APOPLAST ELECTROLYTE DURING THE NORMAL IRRIGATION CYCLE. A THREE WINDOW MICROPROBE WILL BE FABRICATED ON A SILICON WAFER SUBSTRATE USING THE PLANAR TECHNIQUES CO ...

THIS PHASE I PROPOSAL CONCERNS AN EVALUATION OF THE POTENTIAL OF THE ALTI-OXY PROCESS TO PRODUCE TI-LI-AL ALLOYS IN POWDER FORM. THE FOLLOW ON PHASE II PROGRAM WOULD INVOLVE PRODUCTION OF SUFFICIENT MATERIAL TO PRODUCE PARTS FOR TESTING.

THE EFFECT OF THREE IMPORTANT PROCESS VARIABLES (ALTERING HEATING OF FEED LIQUID, CHAMBER LENGTH, AND CARRIER GAS TEMPERATURE) ON ENERGY NEEDED TO PRODUCE POTABLE WATER FROM WATERS CONTAINING DISSOLVED SOLIDS BY AN INNOVATIONAL MINIM UM ENERGY USING HEAT AND MASS TRANSFER DEVICE WILL BE INVESTIGATED. THIS DEVICE USES AN INERT CARRIER GAS OPERATING AT NEAR ATMOSPHERIC PRESSURE TO EVAPORATE WATER AN ...

A PILOT SERIES OF THREE COMPUTER-INTERACTIVE VIDEODISK (CIVD) MODULES WILL BE DEVELOPED FOR TEACHING TOPICS IN TRANSFUSION MEDICINE (TM). THE CONTENT OF THE CIVD MODULES IS DETERMINED FROM THE NHLBI NATIONAL TM CURRICULUM AND INCORPORATES BOTH THE ETHICAL AND PSYCHOSOCIAL ISSUES INVOLVED IN THE PRACTICE OF TM. THE AUDIOVISUAL ELEMENT OF THE CIVD PACKAGES WILL BE SUPPLEMENTED BY APPROPRIATE WRITTEN ...

THE ASSOCIATED CORPORATION PROPOSES TO INVESTIGATE AN INTERRELATED THREE-PART KNOWLEDGE BASED SYSTEM HAVING A NATURAL LANGUAGE INTERPRETER, AN EXPERT SYSTEM ANALYZER AND A NATURAL LANGUAGE GENERATOR. TECHNIQUES USING A LEXICALLY/SEMANTICALLY/FUNCTIONALLY FOCUSED DICTIONARY, PARSER, ANALYSER WHICH TAKES ADVANTAGE OF REPETITIVE LEXICAL STRINGS ARE PROPOSED FOR NATURAL LANGUAGE PROCESSING. INVESTIGAT ...

N/A

THE OBJECT OF THIS RESEARCH IS THE DESIGN OF A CONTROL AND PROTECTION SYSTEM THAT CAN EXHIBIT HIGH RELIABILITY THROUGH THE USE OF FAULT TOLERANCE. WHILE MANY FAULT TOLERANT COMPUTER SYSTEMS HAVE BEEN DEVELOPED, AN INTEGRATED SYSTEMS APPROACH DEMANDS THAT OTHER FACTORS MUST BE INCLUDED. WE ARE PARTICULARLY CONCERNED WITH THE INTERFACES BETWEEN THE VARIOUS SUBSYSTEMS OR ELEMENTS OF THE TOTAL SYSTEM. ...

FOR FUTURE LONG-TERM SPACE MISSIONS SPACECRAFT WATER RECYCLE SYSTEMS ARE NOW UNDER DEVELOPMENT. ONE WATER RECYCLE SYSTEM STUDIED BY NASA INCLUDES A REVERSE-OSMOSIS (RO) SUBSYSTEM THAT WILL PRODUCE REUSABLE WATER FROM WASH WATERS. THE CONCENTRATE FROM THE RO SUBSYSTEM WILL BE COMBINED WITH URINE AND DISTILLED TO RECOVER MORE WATER. THIS PROJECT WILL INVESTIGATE THE USE OF AN ADDITIONAL RO COMPONENT ...

A SIGNIFICANT PROBLEM IN THE USE OF DOMESTIC COAL RESOURCES TO GENERATE POWER IS THE PRODUCTION OF SO2 IN POWER-PLANT STACK GASES FROM THE COMBUSTION OF SULFUR IN THE COAL. STATE-OF-THE-ART SO2 SCRUBBING TECHNOLOGY, CENTERED AROUND LIQUID/GAS CONTACTORS, IS EXPENSIVE AND HAS OPERATIONAL DRAWBACKS. A NEW TECH- NOLOGY TO BE STUDIED HERE RELIES ON USING SO2-PERMEABLE MEMBRANES TO REMOVE SO2 FROM STAC ...
