  1. 21. 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. 22. Scrap happens, but does it have to? On the potential of increasing machine component reuse

    Författare :Derek Diener; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; component; circular economy; obsolescence; remanufacturing; reuse;

    Sammanfattning : The vision of the “circular economy” provides some guidelines for society to strive towards. In the circular economy, material resources are used and reused and recycled better, if not endlessly. Products are to require less material and deliver more function. LÄS MER

  4. 23. Particulate Formation in Gasoline Direct Injection Engines

    Författare :Sreelekha Etikyala; 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; PM; Volatileorganic compounds; Gasoline Direct Injection; Particulate Number; Alternate fuels;

    Sammanfattning : Gasoline direct injection (GDI) engines are facing a great challenge because of the need to comply with increasingly stringent emission regulations while improving fuel economy. GDI engines are popularly known for their high fuel efficiency (by the standards of gasoline engines) and low emissions, enabling higher compression ratios and thus increased volumetric efficiency.

  5. 24. Operationalizing Industrial Ecology in the Waste Sector : Roles and tactics for circular value innovation

    Författare :Graham Aid; Nils Brandt; Monika Olsson; Maria Malmström; Leenard Baas; Stefan Anderberg; Mats Eklund; Anna Björklund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The take-make-waste approach to resource management in human production and consumption systems is contributing to a variety of environmental and social problems worldwide. Additionally, as the world’s population and affluence increase, so do the negative impacts of poor resource management. LÄS MER

  7. 25. The Technology and Economy of Farm-Scale, High-Solids Anaerobic Digestion of Plant Biomass

    Författare :Mattias Svensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; farm-scale; Bioteknik; farmhouse construction; Lantbruksteknik; Biotechnology; agricultural machines; kontroll av utsläpp; Agricultural engineering; Miljöteknik; pollution control; Environmental technology; Lantbruksekonomi; straw bed priming; stratified bed digesters; nitrogen recycling; greenhouse gases; Sweden; Agricultural economics; sequential single-stage fed-batch; ley crops; sustainability; wheat straw; sugar beet tops; crop residues; high-solids; economy; Anaerobic digestion; biogas upgrading;

    Sammanfattning : Anaerobic digestion is a microbially mediated process occurring in nature in the absence of oxygen and other non-carbonaceous electron acceptors. The majority of the carbon of the organic matter degraded in the process is transformed into carbon dioxide and methane. LÄS MER
