  1. 21. Introducing a Memory Efficient Execution Model in a Tool-Suite for Real-Time Systems

    Författare :Kaj Hänninen; Mikael Nolin; Christer Norström; Jukka Mäki-Turja; Ola Redell; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-Time Systems; Execution Models; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : This thesis shows how development of embedded real-time systems can be made more efficient by introduction of an memory efficient execution model in a commercial development suite. To identify the need of additional support for execution models in development tools, the thesis investigate by a series of interviews, the common requirements in development of industrial embedded real-time systems.

  3. 22. Share-Driven Scheduling of Embedded Networks

    Författare :Thomas Nolte; Hans Hansson; Christer Norström; Sasikumar Punnekkat; Luís Almeida; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; subsystem integration; controller area network; CAN; real-time communication; real-time analysis; server-based scheduling; Server-CAN; Computer engineering; Datorteknik; Datavetenskap;

    Sammanfattning : Many products are built from more or less independently developed subsystems. For instance, a car consists of subsystems for transmission, braking, suspension, etc. These subsystems are frequently controlled by an embedded computer system. LÄS MER

  4. 23. Removal processes in sewage treatment plants : Sludge quality and treatment efficiency of structurally diverse organic compounds

    Författare :Ulrika Olofsson; Peter Haglund; Staffan Lundstedt; Juliane Hollender; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmetrics; flame retardants; GCxGC; non-targeted screening; mass flow; metals; plasticizers; poorly removed contaminants; POP; PPCP; prediction; Principal Component Analysis; removal efficiency; sewage; sewage treatment plants; sludge; sludge adsorption; sources; time-trend analysis; Environmental chemistry; Miljökemi;

    Sammanfattning : Large and ever-increasing numbers of chemicals, including large quantities of a broad spectrum of organic compounds are used in modern society. More than 30 000 of the more than 100 000 chemical substances registered in the EU are estimated to be daily used, of which many will be discharged into the waste-streams handled by municipal sewage treatment plants (STPs).

  5. 24. Medical data time series analyses using AI techniques

    Författare :Jan J. Liszka-Hackzell; Victor Maojo; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In many areas of medicine, we collect serial measurements of different variables as they change over time. Changes in a time series is often reflective of a change in a patient's status and may be helpful in guiding the appropriate therapy. LÄS MER

  7. 25. Resource Optimization in Multi-processor Real-time Systems

    Författare :Hamid Reza Faragardi; Thomas Nolte; Johan Tordsson; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis addresses the topic of resource efficiency in multiprocessor systems in the presence of timing constraints.  Nowadays, almost wherever you look, you find a computing system. Most computing systems employ a multiprocessor platform. LÄS MER
