    Författare :Mattias Gustafsson; Björn O. Karlsson; Mats Rönnelid; Louise Ödlund; Jan-Olof Dalenbäck; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; primary energy; energy efficiency; district heating; building regulations; electric meter; low-voltage distribution networks; electric vehicles; primärenergi; energieffektivitet; fjärrvärme; byggregler; elmätare; elnät; elfordon; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : The traditional energy system as we know it today will change in the future. There is a worldwide concern about the global warming situation and there are different actions implemented to limit the consequences from, mainly, the use of fossil fuels. LÄS MER

  3. 7. Evaluation of energy conserving measures in buildings connected to a district heating system : case studies in Gävle, Sweden

    Författare :Mattias Gustafsson; Björn Karlsson; Magnus Åberg; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energieffektivisering; miljonprogrammet; solceller;

    Sammanfattning : When different energy conserving measures are implemented for reducing energy use in buildings and the buildings are connected to district heating systems, it is important that an overall system analysis is made which takes into account the effects of total change of energy use due to the energy conserving measures.The method applied in this thesis uses hourly production data for the different production units in the district heating system in Gävle, Sweden.

  7. 10. Static WCET Analysis Based on Abstract Interpretation and Counting of Elements

    Författare :Stefan Bygde; Björn Lisper; Andreas Ermedahl; Jan Gustafsson; Konstantinos Sagonas; Ulf Nilsson; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parametric WCET analysis; program analysis; abstract interpretation; Computer science; Datalogi; Computer Science; datavetenskap;

    Sammanfattning : In a real-time system, it is crucial to ensure that all tasks of the system holdtheir deadlines. A missed deadline in a real-time system means that the systemhas not been able to function correctly. If the system is safety critical, this canlead to disaster. LÄS MER
