  2. 1. Massification of the Intangible : An investigation into embodied meaning and information visualization

    Author : Andreas Lund; Erik Stolterman; Pelle Ehn; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Information visualization; theory driven design; embodied realism; massification design; human-computer interaction; Informatik; data- och systemvetenskap; Informatics; computer and systems science; Informatik; data- och systemvetenskap; människa-datorinteraktion; människa-datorinteraktion;

    Abstract : The thesis addresses two related problems. It is argued that the materiality of physical artifacts serves the purpose of expressing abstract information. In contrast, the intangibility of IT is of such a kind that it poses different conditions for expressing abstract information. READ MORE

  4. 2. New methods for movement technique development in cross-country skiing using mathematical models and simulation

    Author : Marie Lund Ohlsson; Mårten Gulliksson; Lars-Erik Persson; Fredrik Ståhl; Peter Carlsson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied mathematics; Tillämpad matematik;

    Abstract : This Licentiate Thesis is devoted to the presentation and discussion of some new contributions in applied mathematics directed towards scientific computing in sports engineering. It considers inverse problems of biomechanical simulations with rigid body musculoskeletal systems especially in cross-country skiing. READ MORE

  5. 3. National Energy System Modelling of Industry : Optimising the Transition Towards Carbon Neutrality

    Author : Erik Sandberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Peter Lund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : Industry is a major user of energy and emitter of fossil CO2. At the same time, Sweden targets net-zero greenhouse gas emissions by 2045. Current policies to reduce greenhouse gas emissions and mitigate climate change, and the transition of the energy system it requires, will present major challenges for industry. READ MORE

  6. 4. Topology optimization of vehicle body structures : method, theory and applications

    Author : Harald Fredricson; Erik Lund; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This dissertation is concerned with topology optimization of vehicle body structures.The first part of this thesis gives a summary of the research project. A design process for complex mechanical structures is presented. This design process includes an optimization step where simplified models are optimized. READ MORE

  7. 5. Cost Optimization of Aircraft Structures

    Author : Markus Kaufmann; Dan Zenkert; Malin Åkermo; Per Wennhage; Erik Lund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; Vehicle engineering; Farkostteknik;

    Abstract : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. READ MORE
