  1. 1. Acoustic Manipulation of Particles and Fluids in Microfluidic Systems

    Författare :Linda Johansson; Stefan Johansson; Martin Wiklund; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : The downscaling and integration of biomedical analyses onto a single chip offers several advantages in speed, cost, parallelism and de-centralization. Acoustic radiation forces are attractive to use in these applications since they are strong, long-range and gentle. LÄS MER

  3. 3. Participatory inquiry : Collaborative Design

    Författare :Martin Johansson; Malmö högskola; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Design informed by ethnography; Work practice based design; Participatory inquiry; Collaborative design; Design games; Interaction Design; Human Computer Interaction; Participatory Design;

    Sammanfattning : This dissertation focuses on design sessions in which users and stakeholders participate. It demonstrates how material from field studies can be used in exploratory design sessions. The emphasis is on the staging and realization of experiments with ‘possible futures’. LÄS MER

  4. 4. Aerothermal Study of Intermediate Turbine Ducts

    Författare :Martin Johansson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerodynamics; Intermediate Turbine Duct; Gas Turbine; Heat Transfer; Experimental;

    Sammanfattning : An intermediate turbine duct guides the flow from the smaller diameter high pressure turbine to the downstream larger diameter intermediate or low pressure turbine. It is typically equipped with a structural vane transferring loads for the core to the external parts, and supplies the core with necessary services such as oil and air. LÄS MER

  5. 5. Characterization of catalytic reactions on surfaces from three-dimensional partial pressure distributions

    Författare :Martin Johansson; Bengt Andersson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : A chemical reaction taking place on a surface exposed to a viscous gas will give rise to a nonhomogeneous gas composition and temperature in the vicinity of the surface. This is due to the limited rate at which species and heat can be transported in the gas mixture by convection and diffusion. LÄS MER
