  1. 6. Exploring Tensions between Appropriability and Openness to Collaboration in Innovation

    Författare :Ioana Stefan; Lars Bengtsson; Frishammar Johan; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Appropriability; Openness; Tensions; Open Innovation; Performance; Intellectual Property Rights; Territoriality; Location; Intellectual Property Protection Mechanisms; Paradox; Dilemma; Dialectic; Intelligent industri; Intelligent Industry; Industriell ekonomi och organisation;

    Sammanfattning : Researchers, policy makers and practitioners alike have in recent years acknowledged a growing tendency towards opening up the innovation process by combining internal organizational assets with external actors’ resources. However, opening up the innovation process usually also entails revealing ideas, which may result in misappropriation. LÄS MER

  3. 7. Time-domain modelling of curve squeal: a fast model for one- and two-point wheel/rail contact

    Författare :Ivan Zenzerovic; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; two-point contact; non-Hertzian contact; dynamics coupling; rolling contact; tangential point-contact model; Curve squeal; time domain; frictional instability;

    Sammanfattning : Curve squeal is a type of railway noise that may arise when a railway vehicle negotiates a relatively tight curve. A single frequency, corresponding to a wheel mode, dominates the radiated sound, which makes squeal a very tonal noise. LÄS MER

  4. 8. Deformation mechanisms and load distribution in multi-phase engineering materials

    Författare :Nitesh Raj Jaladurgam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deformation mechanisms; Electron microscopy; Eutectic high entropy alloys; Load distribution; Superalloys; In-situ neutron diffraction;

    Sammanfattning : While the transition to carbon neutral technologies is still in progress, it is vital to reduce the environmental impact of existing processes. The efficiency of combustion processes for e.g. power generation and aviation can be greatly improved by increasing the operating temperature. LÄS MER

  5. 9. Knowing the Ropes in Open Innovation : Understanding Tensions through a Paradox Lens

    Författare :Ioana Stefan; Lars Bengtsson; Marcel Bogers; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensions; open innovation; paradox of disclosure; value co-creation; value capture; openness; appropriability; intellectual property rights; misappropriation; paradox lens; spänningar; öppen innovation; paradox om avslöjande; samskapande av värde; värdefångst; öppenhet; immateriella rättigheter; idé missbruk; paradoxteori lins; Intelligent industri; Intelligent Industry; Industriell ekonomi och organisation;

    Sammanfattning : The fundamental paradox of disclosure suggested by Kenneth Arrow represents a challenge in contemporary open innovation settings. Potential negative outcomes of this paradox – e.g. misappropriation of ideas – are still not fully avertable. LÄS MER

  7. 10. Detection of blade icing and its influence on wind turbine vibrations

    Författare :Sudhakar Gantasala; Jan-Olov Aidanpää; Michel Cervantes; Jean-Claude Luneno; Viktor Berbyuk; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : Wind turbine installations in extreme conditions like cold climate have increased over thelast few years and expected to grow in future in North America, Europe, and Asia regions due to good wind resources and land availability. Their installed capacity could reach 186 GW by the end of 2020. LÄS MER
