    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow control; plasma actuator; wing; leading edge; flat plate; wind turbine; optimal controller; model reduction; proper orthogonal decomposition; dynamic mode decomposition.;

    Sammanfattning : In this thesis direct numerical simulation is used to investigate the possibility to delay the transition from a laminar to a turbulent flow in boundary layer flows. Furthermore, modal analysis techniques are used to identify the coherent structures in wind turbine wake. LÄS MER

  4. 3. Fostering Dynamic Capabilities of SMEs. The Impact of Inward International Licensing on Absorptive Capacity and Networking Capability : A Multiple Case Study in Pharmaceutical Industry

    Författare :Mohammad Reza Saeedi; Hossein Dadfar; Staffan Brege; Peter Ekman; Linköpings universitet; []
    Nyckelord :Absorptive capacity; networking capability; inward international licensing; dynamic capabilities; SMEs; Iran;

    Sammanfattning : Resource limitation and inadequate capabilities are the SME’s major problems. On this basis, alliances as vehicles of inter-firm collaboration provide opportunities for SMEs to obtain complementary capabilities and critical resources to overcome resource limitations. LÄS MER
