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

    Författare :Piotr Lukaszewicz; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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; Vehicle engineering; 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

    Författare :Yang Xu; Institutionen för reglerteknik; []

    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

    Författare :Paul Pop; Petru Eles; Zebo Peng; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; communication-intensive heterogeneous real-time systems; multi-cluster systems; time-driven; event-driven; distributed embedded systems; Computer science; 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

    Författare :Johan Hagelbäck; Stefan J. Johan; Pieter Spronck; Blekinge Tekniska Högskola; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; real-time strategy; potential fields; multi-agent systems; emergent behavior; Computer Science; Datavetenskap; 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

    Författare :Flavius Gruian; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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
