  1. 1. Test Design for Finite Element Model Updating : Identifiable Parameters and Informative Test Data

    Detta är en avhandling från Göteborg : Chalmers tekniska högskola

    Författare :Andreas Linderholt; Thomas Abrahamsson; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Test Design Finite Element Model Updating Informativeness Identifiability optimization Fisher information modal tests; Maskinteknik; Mechanical Engineering;

    Sammanfattning : It is important to predict structural phenomena, such as noise and fatigue, stemming from vibra- tions. To do this, reliable structural dynamic models are needed. To be useful the models have to compare well with reality in the validation against test data; if not, the models should be mod- ified. LÄS MER

  2. 2. The temporality of in-vehicle user experience: exploring user experiences from past to future

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Ingrid M Pettersson; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Methodology; Over Time; In-Vehicle Systems; Design; User Experience; Automotive; Future; Human Machine Interaction; Temporality;

    Sammanfattning : Cars are nowadays equipped with numerous interactive systems, aiding the driver by providing safety warnings, driving information, support, connectivity and entertainment. Traditionally in the field of in-vehicle system design, the focus of the automotive industry been on safety, i.e. on distraction measures and usability. LÄS MER

  3. 3. Biogas Production from Lignocelluloses Pretreatment, Substrate Characterization, Co-digestion and Economic Evaluation

    Detta är en avhandling från Chalmers Tekniska Högskola

    Författare :Anna Teghammar; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; lignocellulose; pretreatment; anaerobic digestion; co-digestion; substrate characterization; economic evaluation; Biotechnology;

    Sammanfattning : Biogas production from organic materials can be used as a renewable vehicle fuel, provide heat and generate electricity and can thereby reduce the greenhouse gas emissions. This thesis focuses on the biogas production based on lignocelluloses. There is an abundant availability of lignocelluloses, constituting 50% of the total biomass worldwide. LÄS MER

  4. 4. A Process View of Business Model Innovation

    Detta är en avhandling från Gothenburg : Chalmers Reproservice

    Författare :Sara Fallahi; Joakim Björkdahl; Stefan Haefliger; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; business model; innovation; process; cognitive search; experiential learning; ambidexterity; resource based view; ;

    Sammanfattning : In an era of globalization, cross-fertilization of technologies and industries, and changing markets, firms are introducing new ways of creating or capturing value through Business Model Innovations (BMI). In recent years, BMI has become one of the priorities of practitioners, and has attracted the interest of scholars since product or process innovations on their own are perceived insufficient in the current internet era when other sources of competitive advantage are being needed.

  5. 5. On Sustainability of Biomass for Energy and the Governance Thereof

    Detta är en avhandling från Chalmers University of Technology

    Författare :Oskar Englund; Virginia Dale; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e. LÄS MER
