In this paper, we present a system called Ubiquitous Learning Support System for Multi-devices. In this system, learners could access the server anddownload learning resources in two modes through wireless communication devices in line with J2ME. In this paper, we introduce the design of this system.

BrOWN, dWrEPP, JrTAYLOr, OSD. W. Brown is an engineer at the Westinghouse Research and Development Center. He received a B.S. in mechanical engineering from Michigan Technological University and an M.S.
in mechanical engineering from Michigan State University. Mr. Brown joined Westinghouse in 1986 and has since worked on such projects as the testing and analysis of current collection apparatus the design of shaft and bearing arrangements for high speed electrical motors and the design of a submersible electric motor. He also has experience in the use and analysis of fiber-reinforced composites at room temperature and at cryogenic temperatures. This knowledge of composites was applied to a study involving a fibrous composite robot arm. Mr. Brown is working on the rotor design of a cryogenically cooled AF generator and also the design of the vertical motor test facility for the Motor Silencing Program. Jeffrey R. Repp is a senior engineer with Westinghouse Research and Development Center. He received a B.S. in electrical engineering from Pennsylvania State University
an M.S. in electrical engineering from the University of Cincinnati and an M.B.A. in management/industrial management from Xavier University. Mr. Repp has 13 years of experience in the field of electrical engineering
specializing in the design and analysis of electromagnetic devices. This experience includes the development design testing and analysis of a wide variety of electric motors ranging from fractional horsepower permanent magnet motors through large (10000 hp) synchronous and induction motors. Mr. Repp has been directly involved in the electromagnetic and thermal analyses of machines utilizing state-of-the-art finite element and computer graphic techniques. Most recently he has been concerned with the development of electronically commutated permanent magnet (brushless dc) products. Mr. Repp is a Member Institute of Electrical and Electronics Engineers IEEE Power Engineering Society. O. S. Taylor is manager of electromechanical applications

Mr. Taylor has more than 18 years of experience in the field of research anddevelopment engineering. Since joining Westinghouse in 1974 he has been involved in the design anddevelopment of advanced electrical machinery including large, high powerdensity motors for electric drive ship propulsion, pulsed homopolar generators for electromagnetic launchers, high current density contacts for switching applications, research in automated manufacturing, androbotic system development. He is currently managing a section that deals with rotating power equipment for military applications, with emphasis on thermal and electromagnetic modeling. ABSTrACT A demonstration submersible outboard electric motor/ propulsor has been designed, built, and successfully tested. This concept involves mounting a propellerdirectly inside a rotor of a specially designed induction motor. This motor/ propulsor has the advantages of direct seawater cooling and bearing lubrication, direct drive, shrouded propeller, variable positioning, easy access, and high maneuverability. The motor/propulsor is readily adaptable to dual, independently-controlled and contra-rotating propellers without the need for gears. The concept has been investigated conceptually for application to primary propulsion, secondary propulsion, and poddrives, for amphibious, surface, and undersea vehicles.
Using the framework of the parallel logical language. Concurrent Prolog, the concepts and the strategies for the parallel logic simulation are defined. Some types of a prototypical parallel logic simulator are impleme...
