    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete event systems; IC3; large-scale systems; model checking; incremental control; supervisory control; hierarchical control; maximal permissiveness;

    Sammanfattning : Today's industry trend towards agile product development cycles and the ambition to shorten the time-to-market, represents an extremely competitive marketplace. This has driven the industry to use very complex and highly flexible manufacturing systems. LÄS MER

  3. 17. Control Synthesis for Batch Processes

    Författare :Michael Tittus; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; batch control; hybrid systems; modeling; control synthesis; supervisory control; object-orientation; resource allocation;

    Sammanfattning : Batch applications form an important application class within the field of process industries. In this thesis we propose multiple models, frameworks and design concepts in order to apply formal methods to the control synthesis in batch control. The thes is can be divided into two main parts.

  4. 18. The Usefulness of ICT Support Systems for Thesis Courses : Learners' Perspectives at Bachelor and Master Level

    Författare :Naghmeh Aghaee; Henrik Hansson; Christina Keller; Matti Tedre; Ola Lindberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information and Communication Technologies ICT ; Support System; interaction; thesis; self-managed learning; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : Doing a bachelor’s or master’s degree is a journey that leads to success or attrition (dropout). Previous research show to the significance of considering learners’ perspectives and their need for information and different types of interaction. This can be done through online ICTSS (information and communication technology support systems). LÄS MER

  5. 19. Vägen in i ett yrke : en studie av lärande och kunskasputveckling hos nyutbildade sjuksköterskor

    Författare :Ulla Ohlsson; Bernt Gustavsson; Kjell Gustavsson; Kristin Heggen; Örebro universitet; []
