  1. 6. Advancing Front Mesh Generation Techniques with Application to the Finite Element Method

    Författare :Jan Frykestig; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advancing front method; mesh size distribution; automatic mesh generation; finite element method; surface mesh generation; spatial data structures;

    Sammanfattning : The present study deals with automatic mesh generation with application to finite element methods. We focus our interest on unstructured mesh generation, and in particular on advancing front methods for which algorithms for meshing of two and three dimensional domains as well as of free-form surfaces are devised.

  3. 7. Optimal Truck Scheduling : Mathematical Modeling and Solution by the Column Generation Principle

    Författare :Myrna Palmgren; Torbjörn Larsson; Niklas Kohl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimisation; pickup and delivery problem; transportation; scheduling; column generation; integer programming; MATHEMATICS; MATEMATIK;

    Sammanfattning : We consider the daily transportation problem in forestry which arises when transporting logs from forest sites to customers such as sawmills and pulp and paper mills. Each customer requires a specific amount of a certain assortment, and the deliveries to the customers can be made within time intervals, known as time windows. LÄS MER

  4. 8. Exploring student collaboration during Data Generation in the Statistics Classroom : An Inferentialist Perspective

    Författare :Abdel Seidouvy; Maike Schindler; Ola Helenius; Dani Ben-Zvi; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inferentialism; Collaboration; Data generation; Statistics;

    Sammanfattning : This dissertation explores student collaboration during data generation in statistics. The first aim is to put the semantic theory of inferentialism to work and develop a theoretical lens for exploring student collaboration during data generation. LÄS MER

  5. 9. Techno-economic evaluation of integrated lignocellulosic ethanol production

    Författare :Elisabeth Joelsson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distillers dried grain with solubles; biorefinery; modelling; Aspen Plus; biogas; logging residues; spruce; wheat straw; wheat grain; heat; integration; pinch analysis; techno-economic evaluation; first generation; second generation; Ethanol; Lignocellulosic material;

    Sammanfattning : Sweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. LÄS MER

  7. 10. Fields of Gold : The Bioenergy Debate in International Organizations

    Författare :Magdalena Kuchler; Björn-Ola Linnér; Johan Hedrén; Eva Friman; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; bioenergy; biofuels; debate; discourse; concept; international organizations; international relations; FAO; IEA; IPCC; energy security; climate change; food security; food vs. fuel; bioenergi; biobränsle; debatt; diskurs; begrepp; internationella organisationer; internationella relationer; FAO; IEA; IPCC; energisäkerhet; klimatförändringar; livsmedelssäkerhet;

    Sammanfattning : The concept of producing energy from biomass has, for the last two decades, occupied attention of policy-makers, private industries, researchers and civil societies around the world. The highly contested and contingent character of the biofuel production, its entanglement in the nexus of three problematic issues of energy, climate and agriculture, as well as its injection into the current socioeconomic arrangements, is what makes it timely to analyse.
