A NOVEL CLASS OF TIME AND POSITION SENSITIVE (XYT) PARTICLE DETECTOR AND SUPPORTING ELECTRONICS IS PROPOSED WHICH CAN AFFORD A PRACTICAL MEANS OF COMBINING IMAGING AND TIME-OF-FLIGHT (TOF) ANALYSES IN A VARIETY OF ADVANCED INSTRUMENTS. DETECTOR SYSTEMS FOR PHOTONS, ELECTRONS AND IONS ARE TYPICALLY THE FIRST COMPONENTS IN MATERIALS CHARACTERIZATION INSTRUMENTS; FUNDAMENTAL IMPROVEMENTS HERE CAN HAV ...

THIS RESEARCH WILL EXPLORE THE POSSIBILITIES AND RESULT IN THE DESIGN OF AN ACOUSTIC ENERGY GENERATOR FOR GEOPHYSICAL EXPLORATION IN INACCESSIBLE MOUNTAINOUS TERRAIN. THIS EFFORT WILL DETERMINE THE MAGNITUDE OF ACOUSTIC SIGNAL REQUIRED AND WILL DEVELOP A TECHNIQUE FOR COUPLING THE SIGNAL GENERATOR TO THE EARTH. THE COUPLING TECHNIQUE WILL EXAMINE FORCES OTHER THAN GRAVITY TO ENSURE THAT THE SIGNAL ...

A MAJOR PROBLEM ASSOCIATED WITH THE USE OF ULTRA-HIGH-RESOLUTION GAS CHROMATOGRAPHY FOR EFFLUENT MONITORING IS THE RELATIVELY LOW SPEED OF ANALYSIS. WE PROPOSE TO DEVELOP AN ULTRA-HIGH-SPEED CAPILLARY GAS CHROMATOGRAPH WHICH WOULD BE SUITABLE FOR THE ANALYSIS OF EFFLUENT SAMPLES IN JUST A FEW SECONDS. THE HEART OF THE NEW INSTRUMENT WOULD BE A MICROBORE COLUMN WITH AN INTERNAL DIAMETER OF 50 MUM O ...

As fire protection engineering moves towards the implementation of performance- based fire codes, the use of validated fire models is becoming a necessity. Part of the validation process involves demonstrating model capabilities for predicting key fire environment parameters. One of the key parameters for estimating time to ignition and fire growth is the heat transfer rate to compartment surfaces ...

HIGH POWER TRANSIT-TIME AMPLIFIERS ARE A NEW CLASS OF RF SOURCE THAT CONVERTS THE KINETIC ENERGY OF AN ELECTRON BEAM INTO RF RADIATION IN A VERY EFFICIENT WAY. WHEN THE BEAM CROSSES THE CAVITY OF PROPER DIMENSIONS, IT WILL INTERACT WITH A SINGLE CAVITY MODE THEREBY RADIATING COHERENTLY AT THE MODE'S FREQUENCY. MODE GROWTH CONTINUES UNABATED UNTIL THE RF FIELDS ARE LARGE ENOUGH TO MODIFY THE BEAM O ...
