    Författare :Josina Vink; Bård Tronvoll; Bo Edvardsson; Katarina Wetter-Edman; Birgit Mager; Raymond P. Fisk; Karlstads universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; service design; service research; service ecosystems; social structures; systemic design; institutional theory; service-dominant logic; Business Administration; Företagsekonomi;

    Sammanfattning : This thesis explores and advances the evolving understanding of service design in service research. The study problematizes the prevailing view of service design as the design of service offerings to improve customer experiences. LÄS MER

  5. 4. Dynamics of Exhaust Valve Flows and Confined Bluff Body Vortex Shedding

    Författare :Marcus Winroth; P. Henrik Alfredsson; Knud Erik Meyer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : This thesis can be divided into two interconnected topics; engine exhaust-valve flows and confined bluff-body vortex shedding. When optimising engine flow systems it is common to use low order simulation tools that require empirical inputs, for instance with respect to flow losses across the exhaust valves. LÄS MER

  7. 5. Electrokinetic devices from polymeric materials

    Författare :Katarina Bengtsson; Nathaniel D Robinson; Mats Fahlman; Jörg P. Kutter; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : There are multiple applications for polymers: our bodies are built of them, plastic bags and boxes used for storage are composed of them, as are the shells for electronics, TVs, computers, clothes etc. Many polymers are cheap, and easy to manufacture and process which make them suitable for disposable systems.
