MUCH OF THE RESEARCH ON OUTSTANDING PROBLEMS IN METEOROLOGY AND CLIMATE DYNAMICS WOULD PROFIT GREATLY FROM THE AVAILABILITY OF INEXPENSIVE IN-SITU MEASUREMENTS OF THE ATMOSPHERE. THE NATIONAL CENTER FOR ATMOSPHERIC RESEARCH (NCAR) HAS DEVELOPED A FAMILY OF LIGHTWEIGHT DIGITAL DROPWINDSONDES, AND AURORA FLIGHT SCIENCES HAS DEVELOPED A LOW-COST UNMANNED SCIENTIFIC RESEARCH AIRCRAFT (USRA) NAMED PERS ...

COMPUTED TOMOGRAPHY (CT) HAS BECOME INCREASINGLY IMPORTANT IN NONDESTRUCTIVE EVALUATION (NDE). INDUSTRIAL APPLICATIONSOFTEN REQUIRE VERY HIGH SPATIAL RESOLUTION. HOWEVER, THE FINITE WIDTH OF X-RAY SAMPLING LIMITS THE SPATIAL RESOLUTION. THE RESEARCH TO BE CARRIED OUT HERE WILL INVESTIGATE AN EFFICIENT COMPUTATIONAL METHOD TO DECONVOLVE THE BEAM WIDTH FROM THE PROJECTION DATA WITHOUT INCREASING THE ...

LEADING SCIENTISTS AND EDUCATORS HAVE STRESSED CRITICAL THINKING PROBLEM SOLVING AS TOP PRIORITIES FOR SCIENCE EDUCATION. A NEGLECTED ASPECT OF THIS BROAD AREA IS THE ABILITY TO MAKE GOOD DECISIONS THROUGH LOGICAL HABITS OF THOUGHT RELATING KNOWLEDGE, UNCERTAINTY AND HUMAN VALUES. SUCH SKILLS ARE TAUGHT IN ONLY A FEW SECONDARY SCHOOLS, AND TEACHING/LEARNING MATERIALS FOR THIS AREA ARE NOT AVAILABL ...

THIS PROPOSED PROGRAM IS DIRECTED TOWARDS THE EXPERIMENTAL EVALUATION OF MIXED IONIC AND ELECTRONIC CONDUCTING MEMBRANES FOR PROMOTING THE ELECTROCHEMICAL CATHODIC DECOMPOSITION OF N0X WITHIN AUTOMOBILE EXHAUSTS. THE APPROACH WILL RELY UPON THE SYSTEMATIC APPLICATION OF PEROVSKITE CATHODE ELECTROCATALYSTS WHICH, WE FEEL, WILL PROVIDE RAPID KINETICS FOR PROMOTING THE ELECTROCHEMICAL REDUCTION OF TH ...

THIS PROPOSED PROGRAM ADDRESSES THE NEED FOR DEVELOPMENT OF THIN CERAMIC MEMBRANES FOR ACHIEVING RELIABLE OXYGEN SEPARATION AT ELEVATED TEMPERATURES. TECHNICAL EFFORT WILL BE DIRECTED TOWARDS DEVELOPMENT OF AMBIENT TEMPERATURE ELECTROLYTIC TECHNIQUE FOR THE PREPARATION OF THIN FILM CERAMIC MIXED IONIC AND ELECTRONIC CONDUCTORS (MIEC) FOR USEAS OXYGEN SEPARATION MEMBRANES. THESE MEMBRANES WILL BE B ...

THIS PROGRAM ADDRESSES A NOVEL STRATEGY FOR DIRECTLY ACTIVATING METHANE TO METHANOL ACROSS A MIXED IONIC AND ELECTRONIC CONDUCTING CERAMIC MEMBRANE AT TEMPERATURES BETWEEN 200 AND 400 DEGREES CENTIGRADE. THE APPROACH RELIES UPON INITIAL HETEROGENEOUS GENERATION OF HALIDE SPECIES COMPATIBLE WITH SUBSEQUENT METHANE ACTIVATION, VIA HYDROGEN ABSTRACTION, TO GIVE AN INTERMEDIATE METHYL HALIDE SPECIES. ...

MULTIPATH FADING ON RADIO CHANNELS SERIOUSLY HAMPERS HIGH SPEED DIGITAL COMMUNICATIONS. TIME-VARYING AMPLITUDE AND PHASE FORCE CONVENTIONAL SYSTEMS TO OPERATE AT DATA RATES FAR BELOW CHANNEL CAPACITY. DIVERSITY AND ERROR-CORRECTION CODING TECHNIQUES HAVE NOT SOLVED THE PROBLEM COMPLETELY ANDHAVE INTRODUCED UNDESIRABLE SIDE EFFECTS IN THE PROCESS. WEPROPOSE TO INVESTIGATE A NEW APPROACH THAT ADAPTS ...

DIAMOND FILMS ARE CONTEMPLATED FOR USE IN OPTICAL SYSTEMS DUE TO THEIR INERT NATURE AND HENCE THEIR ABILITY TO PROTECT THE VITAL OPTICAL SYSTEMS FROM THE HARSH ENVIRONMENTS. POLYCRYSTALLINE DIAMOND FILMS PRODUCE SCATTERING CENTERS DUE TO THE DIFFERENT IMPURITIES, GRAIN SIZES AND ORIENTATIONS THAT ARE PRODUCED BY THE DIFFERENT DEPOSITION TECHNIQUES. A NOVEL POLISHING METHOD IS PROPOSEDFOR PROVIDING ...

IMPROVED RELIABLE ACCELEROMETERS SUITABLE FOR WIDE DEPLOYMENT IN SEISMIC ARRAYS ARE NEEDED FOR EARTHQUAKE PREDICTION STUDIES. IN RESPONSE TO THIS NEED OPTICAL TECHNOLOGIES, INC. (OPTECH) IS PROPOSING A FIBER-OPTIC ACCELEROMETER SYSTEM THAT PROVIDES THE DESIRED PERFORMANCE IMPROVEMENTS OF BROAD-BAND, WIDE DYNAMIC RANGE, AND LOW POWER CONSUMPTION, AS WELL AS OTHER SIGNIFICANT BENEFITS ANDFEATURES: B ...
