  1. 16. "Share weather" : Design and evaluation of a new concept for sharing weather information

    Författare :Katarina Elevant; Stefan Hrastinski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Already centuries ago, humans had observed the weather in their everyday lives, seeking ways to understand, comprehend, and predict it. Until the present day, weather has had tremendous impacts on our lives and with climate change human civilizations as well. LÄS MER

  3. 17. Development of radiofrequency pulses for fast and motion-robust brain MRI

    Författare :Ola Norbeck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis is based on three projects and the three scientific articles that were the result of each project. Each project deals with various kinds of technical software development in the field of magnetic resonance imaging (MRI). The projects are in many ways very different, encompassing several acquisition and reconstruction strategies. LÄS MER

  4. 18. Strategic Life-Cycle Modeling and Simulation for Sustainable Product Innovation

    Författare :Henrik Ny; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable product innovation; planning; strategy; backcasting; life-cycle assessment LCA ; strategic life-cycle management SLCM ; systems; modeling; simulation;

    Sammanfattning : Many specific methods and tools have been developed to deal with sustainability problems. However, without a unifying theory it is unclear how these relate to each other and how they can be used strategically. A Framework for Strategic Sustainable Development (FSSD) is being developed to cover this need for clarity and structure. LÄS MER

  5. 19. Advancing CSR in the mining industry : A stakeholder and management system approach
