Confinement Of Electron Orbits And The Interaction Between The Electron Beam And Cavity Modes In The Orbitron Maser, Wlodzimierz Nakonieczny
Doctoral Dissertations
The Orbitron maser, developed over recent years in the University of Tennessee Plasma Laboratory, is an alternative microwave source, capable of producing microwave radiation up to the submillimeter range. It operates on the basis of interaction between an electrostatically confined electron cloud and electromagnetic field in the Orbitron resonator. Good confinement of the cloud is very important for an efficient operation of the Orbitron, and is directly related to the shape of electron orbits in the device. It appears that the radial confinement can be determined by two simple criteria concerning the electron's angular momentum L and energy E. The …

A Parallel Branch And Bound Algorithm For Integer Linear Programming Models, Rochelle L. Boehning
Doctoral Dissertations
"A parallel branch and bound algorithm is developed for use with MIMD computers to study the efficiency of parallel processors on general integer linear programming problems. The Haldi and IBM test problems and a System Design model are used in the implementation of the algorithm. Initially the algorithm solves the Haldi and IBM test problems on a single processor computer which simulates a multiple processor computer. The algorithm is then implemented on the Denelcor HEP multiprocessor using two of the IBM problems to compare the results of the simulation to the results using an MIMD computer. Finally the algorithm is …
