  1. 1. Open Source Business Model : Balancing Customers and Community

    Författare :Thomas Rosén; Staffan Brege; Anna Öhrwall-Rönnbäck; Stefan Hrastinski; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Open Source Software; Business Models; Strategic Management; Market Positioning; Resource Based View; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : Free and Open Source Software has not only increased researchers’ interest about community-driven software development, but lately, interest from commercial actors increased as well. In addition, some scientists have claimed that Open Source Software has entered a new phase: OSS 2.0. LÄS MER

  3. 2. Source Term Model Approaches to Film Cooling Simulations

    Författare :Petter Dahlander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Film cooling simulations using Computational Fluid Dynamics (CFD) are very difficult and extremely computer power demanding. This thesis deals with the development of a method to save computer power for these types of simulations. The cooling air is injected using additions to the source terms of the discretised governing equations. LÄS MER

  4. 3. Logistics-based Competition : A Business Model Approach

    Författare :Tobias Kihlén; Mats Abrahamsson; Daniel Kindström; Andreas Norrman; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; logistics-based competition; business model; logistics strategy; strategy; logistics; Business and economics; Ekonomi;

    Sammanfattning : Logistics is increasingly becoming recognised as a source of competitive advantage, both in practice and in academia. The possible strategic impact of logistics makes it important to gain deeper insight into the role of logistics in the strategy of the firm. LÄS MER

  5. 4. Air Pollution Dependency on Climate Variability and Source Region : Past, Current and Future Air Pollution Scenarios over Europe

    Författare :Camilla Andersson; Hans-Christen Hansson; Christer Johansson; Joakim Langner; David Simpson; Peter Builtjes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acidification; Air Pollution; Climate Change; Europe; Numerical Model; Emission; Eutrophication; Key region; Nitrogen Dioxide; Particulate Matter; PM; Source region; Surface Ozone; Tropospheric Ozone; Earth sciences; Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The main objectives of this thesis were to investigate the dependency of European air pollution on climate variability and emission source region. Calculations with a chemistry transport model (CTM) were conducted to investigate the influence of climate variability. LÄS MER

  7. 5. On the long-term behaviour of tension loaded piles in natural soft soils

    Författare :Jorge Yannie; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft clay; piles; creep rupture; rate dependent; tension load; long-term; field test; numerical model; uplift; creep of piles; installation;

    Sammanfattning : The complexity and scale of new infrastructure projects have challenged the current geotechnical design practice. Urban areas are growing at a fast pace in the horizontal and vertical direction, with taller buildings and deeper underground constructions in already densely populated areas. LÄS MER
