  1. 21. Rational bioenergy utilisation in energy systems and impacts on CO2emissions

    Författare :Bertil Wahlund; KTH; []
    Nyckelord :CO2 reduction; energy system; biofuel; CHP; refining; fuel pellets; ethanol; methanol; DME; fuel substitution; sewage water; nitrification;

    Sammanfattning : The increased concentration of greenhouse gases in theatmosphere, in particular CO2, is changing the Earth’s climate. Accordingto the Kyoto protocol, where the international community agreedon binding emission targets, developed countries are committedto reduce their greenhouse gas emissions. LÄS MER

  3. 22. Homogeneous Lean Combustion in Downsized Spark-Ignited Engines

    Författare :Kristoffer Clasén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; lean combustion; emissons; transportation;

    Sammanfattning : Emissions of greenhouse-gasses and noxious compounds from internal combustion engines propelling personal transportation vehicles is an imminent issue in the society. Therefore, it is vital to find means of reducing these emissions to decrease the impacts of transportation. LÄS MER

    Sammanfattning : Peer Effects in Electric Car Adoption: Evidence from SwedenI study peer effects in the diffusion of electric cars in Sweden. To identify peer effects, I use a shift-share IV design that links the renewal of elapsing individual-level, car leasing contracts (i.e., shift) with the propensity to acquire an electric car based on individual traits (i.

  5. 24. Assessment of Telematic Systems for Road Freight Transport

    Författare :Gideon Mbiydzenyuy; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transportation; telematics; architectures; analysis; optimization; clustering; net present value;

    Sammanfattning : The focus of this thesis is the assessment of telematic systems for road freight transport from a planning perspective. The aim is to support strategic decisions related to architectural choices for such systems, with the possibility to achieve synergies by supporting multiple telematic services. LÄS MER

  7. 25. Supply chain optimization in the forest industry

    Författare :Helene Gunnarsson Lidestam; Mikael Rönnqvist; Jan Lundgren; Eldon Gunn; Linköpings universitet; []
