  1. 1. Energy Consumption and Running Time for Trains modelling of running resistance and driver behaviour based on full scale testing

    Detta är en avhandling från Stockholm : KTH

    Författare :Piotr Lukaszewicz; KTH.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; Running time; running resistance; driver behaviour; freight; train; energy coasting method; aerodynamic drag; driver model; degree of coasting; slippage; wind; Energy saving; braking ratio; powering ratio; full scale testing; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. LÄS MER

  2. 2. LQG-Based Real-Time Scheduling and Control Codesign

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Yang Xu; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2017-11-20]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LQG control; Real-time system; Scheduling; Time-delay system;

    Sammanfattning : Having multiple control tasks concurrently running on a single computing platform increases the processor utilization but degrades the control performance due to delay and jitter. In scheduling and control codesign, the objective is to optimize the combined performance of all the controllers, subject to a schedulability constraint. LÄS MER

  3. 3. Analysis and Synthesis of Communication-Intensive Heterogeneous Real-Time Systems

    Detta är en avhandling från Linköping, Sweden : Linköpings universitet

    Författare :Paul Pop; Linköpings universitet.; Linköpings universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; communication-intensive heterogeneous real-time systems; multi-cluster systems; time-driven; event-driven; distributed embedded systems; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Sammanfattning : Embedded computer systemsare now everywhere: from alarm clocks to PDAs, from mobile phones to cars, almost all the devices we use are controlled by embedded computer systems. An important class of embedded computer systems is that of real-time systems, which have to fulfill strict timing requirements. LÄS MER

  4. 4. Multi-Agent Potential Field based Architectures for Real-Time Strategy Game Bots

    Detta är en avhandling från Karlskrona : Blekinge Tekniska Högskola

    Författare :Johan Hagelbäck; Blekinge Tekniska Högskola.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap; real-time strategy; potential fields; multi-agent systems; emergent behavior; Games; Real-Time Strategy; Potential Fields; Multi-Agent Systems;

    Sammanfattning : Real-Time Strategy (RTS) is a sub-genre of strategy games which is running in real-time, typically in a war setting. The player uses workers to gather resources, which in turn are used for creating new buildings, training combat units, build upgrades and do research. The game is won when all buildings of the opponent(s) have been destroyed. LÄS MER

  5. 5. Energy-Centric Scheduling for Real-Time Systems

    Detta är en avhandling från Department of Computer Science, Lund University

    Författare :Flavius Gruian; Lunds universitet.; Lund University.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; Datalogi; Computer science; numerical analysis; System-Level Synthesis; Variable Speed Processors; Dynamic Voltage Scaling; Real-Time Scheduling; Energy Efficient Systems; control; systems; system; kontroll;

    Sammanfattning : Energy consumption is today an important design issue for all kinds of digital systems, and essential for the battery operated ones. An important fraction of this energy is dissipated on the processors running the application software. To reduce this energy consumption, one may, for instance, lower the processor clock frequency and supply voltage. LÄS MER
