  1. 6. 3D-woven Reinforcement in Composites

    Författare :Fredrik Stig; Stefan Hallström; Dan Zenkert; Andrew Long; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Composites made from three-dimensional (3D) textile preforms can reduce  both the weight and manufacturing cost of advanced composite structures  within e.g. aircraft, naval vessels and blades of wind turbines. LÄS MER

  3. 7. Accuracy of turbocharged SI-engine simulations

    Författare :Fredrik Westin; KTH; []
    Nyckelord :boosting; turbocharging; supercharging; modelling; simulation; turbine;

    Sammanfattning : This licentiate thesis deals mainly with modelling ofturbocharged SIengines. A model of a 4-cylinder engine was runin both steady state and transient conditions and the resultswere compared to measured data. Large differences betweenmeasurements and simulations were detected and the reasons forthis discrepancy were investigated. LÄS MER

  4. 8. Flow cytometry for bioprocess control

    Författare :Fredrik Wållberg; KTH; []
    Nyckelord :flow cytometry; partec pas; propidium iodide;

    Sammanfattning : During bio-technical processing it is important to monitorbiological parameters such as cell growth, viability andproduct formation. Many of the analyses traditionally used areslow to perform and provide only average data for thepopulation. LÄS MER

  5. 9. Designing tools forconviviality : A design led exploration of ParticipatoryActivity Mapping

    Författare :Fredrik Sandberg; Sara Ilstedt; Bo Westerlund; Stefan Holmlid; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Convivial tool; design tools; service design; participatory design; space in between; heterogeneous; participatory activity mapping; absent; othering;

    Sammanfattning : This thesis is a report of research work that contributes to the understandingof so-called convivial tools. It does this by describing how small enterprisesuse Participatory Activity Mapping as an approach to changing, as well ascaring about, people and the things that hold their work situations together.

  7. 10. Experimental and numerical analysis of scratching of homogeneous materials

    Författare :Fredrik Wredenberg; Per-Lennart Larsson; Sture Hogmark; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : Paper AAbstractA numerical strategy based on the finite element method and intended for an accurate analysis of the scratch test is presented. For simplicity, but not out of necessity,the material was described by classical Mises elastoplasticity utilising large deformation theory. LÄS MER
