  1. 1. Communication and Cooperation : A Study of the Relationship Between Political Communication and Large-scale Collective Action

    Författare :Stefan Linde; Simon Matti; Sverker Jagers; Carina Lundmark; Lisa Dellmuth; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Collective Action; Political Communication; Climate Change; Political Science; Statsvetenskap;

    Sammanfattning : This thesis investigates the importance of communication for individual cooperation in large-scale collective action dilemmas. In small-scale collective action, where participants have the possibility to meet face-to-face, communication has been shown to drastically increase levels of cooperation. LÄS MER

  3. 2. Deformation of cellulose allomorphs studied by molecular dynamics

    Författare :Cyrus Djahedi; Lars Berglund; Stefan Lundmark; Margareta Åkerholm; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose; Polymer; Molecular Dynamics; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulose-based materials draw their good mechanical properties from the cellu-lose crystal. Improved understanding of crystal properties could lead to a wider range of applications for cellulose-based materials, Cellulose crystals show high axial Youngs modulus. LÄS MER

  5. 4. Analysis of Dynamics of the Tippe Top

    Författare :Nils Rutstam; Stefan Rauch; Hans Lundmark; Tudor Ratiu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Tippe Top is a toy that has the form of a truncated sphere with a small peg. When spun on its spherical part on a flat supporting surface it will start to turn upside down to spin on its peg. LÄS MER

  7. 5. Study of equations for Tippe Top and related rigid bodies

    Författare :Nils Rutstam; Stefan Rauch; Hans Lundmark; Tudor Ratiu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : The Tippe Top consist of a small truncated sphere with a peg as a handle. When it is spun fast enough on its spherical part it starts to turn upside down and ends up spinning on the peg. LÄS MER
