THE PURPOSE OF THIS PROJECT IS TO DETERMINE THE FEASIBILITY OF DEVELOPING AN INTELLIGENT CUSTOMER LOAD CONTROLLER IMPLEMENTED WITH AN EXPERT SYSTEM. CONVENTIONAL ELECTRICAL LOAD CONTROL DEVICES IMPLEMENT CONTROLLING FUNCTIONS BASED ON PREDETERMINED ALGORITHMS WHICH MAKE ASSUMPTIONS ABOUT TYPICAL USE PATTERNS. USE OF AN EXPERT SYSTEM WITH A LEARNING ALGORITHM IN A LOAD CONTROLLER WOULD PERMIT THE C ...

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 ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

THE OBJECTIVE OF OUR PROJECT IS TO DEVELOP NEW MEANS OF PRODUCING SHORT LIVED RADIOISOTOPES FOR POSITRON EMISSION TOMOGRAPHY (PET). THIS MEDICAL DIAGNOSTIC TECHNIQUE IS CAPABLE OF DISCERNING AND IMAGING MEDICALLY INTERESTING PHENOMENA, SUCH AS THE ACTIVITY OF VARIOUS PARTS OF THE BRAIN, OXYGEN FLOW IN THE BODY, AND OTHER QUANTITIES WHICH ARE IMPOSSIBLE TO DETERMINE BY ANY OTHER DIAGNOSTIC TECHNIQU ...

THE NATION DESIRES TO EXPAND THE USE OF CLEAN BURNING, COMPETITIVELY PRICED NATURAL GAS. THE INCREASED DEMAND FOR NATURAL GAS HAS PROMPTED NEW DRILLING IN ESTABLISHED GAS FIELDS. THE PROPER PLACEMENT OF THE NEW WELLS IS DEPENDENT ON THE GAS FORMATION PROPERTIES BETWEEN THE EXISTING WELLS. ONE OF THE PROPERTIES IS THE THICKNESS OF THE GAS BEARING ZONE. IT IS GENERALLY ACCEPTED THAT THE FORMATIO ...
