    Nyckelord :environment; climate; sustainable development; democratic conversations; agenda setting; gate keeper; framing; CDA critical discourse analysis;

    Sammanfattning : The starting point of this study is that the news media in general strongly influence which topics determine the public agenda by their choice of what is considered newsworthy. The study is based on articles from two major Swedish daily newspapers, Svenska Dagbladet and Dagens Nyheter. LÄS MER

  4. 23. Inverter System Design and Control for a Wave Power Substation

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för teknikvetenskaper

    Författare :Rickard Ekström; [2009]
    Nyckelord :;

    Sammanfattning : This Master thesis has been performed as part of the Lysekil wave power project at the Division of Electricity, Uppsala University. Power electronics, placed in a substation, will be required as an interface between the wave power plant and the electrical grid. LÄS MER

  5. 24. Utvärdering av ett system för Rapid Control Prototyping inom området robotstyrning

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Magnus Fredrixon; [2009]
    Nyckelord :;

    Sammanfattning : In this report a system for Rapid Control Prototyping, RCP, is evaluated through an implementation of the motor control methods Field Oriented Control, FOC, and Space Vector Pulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption and resource utilization on the used hardware and on usability for of software. LÄS MER
