This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

AN IMPROVED METHOD OF WEIGHING TRUCKS WHILE IN MOTION IS PROPOSED. TO INCREASE EFFICIENCY AND REDUCE TIME LOST AT WEIGH STATIONS, THE TRUCKING INDUSTRY NEEDS TO EXCHANGE DATA, INCLUDING WEIGHT DATA, BETWEEN MOVING TRUCKS AND ENFORCEMENT FACILITIES. LEGALLY LOADED TRUCKS WOULD THEN BE ABLE TO PROCEED WITHOUT STOPPING. THIS INVOLVES WEIGH-IN-MOTION. PRESENT WEIGHING TECHNIQUES INVOLVE LOAD CELLS OR ...

MODELING ANBD SIMULATIONS ARE USED EXTENSIVELY IN THE DESIGN AND ANALYSIS OF "BULK" EXPLOSIVES DETECTION DEVICES. HOWEVER, OVERSIMPLIFICATION OF THE INPUT MODEL, NAMELY LUGGAGE AND EXPLOSIVE CONTENTS, CAN LEAD TO POOR DETECTOR DESIGNS. MANUAL PRODUCTION OF SUCH INPUT IS COSTLY AND ERROR PRONE. THIS EFFORT WILL AUTOMATE THE PRODUCTION OF SIMULATED LUGGAGE THROUGH THE DEVELOPMENT OF A COMPUTER TOOL. ...

Combustion chemical vapor deposition (CCVD), which was invented by the principal investigator, is a high quality film deposition technique that can inexpensively and quickly apply lead zirconate-titanate (PZT) thin films in a continuos manner. This technology can be used for the production of ferroelectric capacitors. CCVD is low cost, high quality and versatile. It does not require a reaction cha ...
