    Sammanfattning : In the present work, we introduce a never before studied soliton equation called the intermediate mixed Manakov (IMM) equation. Through a pole ansatz, we prove that the equation has N-soliton solutions with pole parameters governed by the hyperbolic Calogero-Moser system. LÄS MER

  3. 2. Creating a Dynamic Model of a Gas Turbine in the MVEM Framework Using an Ellipse Compressor Model

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Edvin Hansson; [2020]
    Nyckelord :Gas turbine; Modeling; control;

    Sammanfattning : The legislations on greenhouse gas emissions are getting tougher and tougher every year. This drives the demand for energy efficient gas turbines with as low emissions as possible. This poses the challenge to manufacturers of constructing gas turbines with lessened environmental impact, but with maintained performance. LÄS MER

  4. 3. Correlation of microstructural damage to functional properties of irradiated carbon fibre based composites used in neutron chopper discs

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära

    Författare :Hanna Molin; [2019]
    Nyckelord :radiation; epoxy; carbon fiber; CFRP; ESS; European Spallation Source; Technology and Engineering;

    Sammanfattning : Understanding material behaviour has in the past enabled human development and will continue to characterize the various stages of our future development. The use of neutrons will greatly affect several research areas, such as sustainable energy production and cancer research, due to their interaction with nuclei. LÄS MER

  5. 4. Partially Parabolic Wind Turbine Flow Modelling

    Master-uppsats, KTH/Mekanik

    Författare :Sebastian Haglund El Gaidi; [2018]
    Nyckelord :Wind turbine flow; Single wind turbine; Computational fluid dynamics; Partially parabolic Navier-Stokes equations; Finite difference method.;

    Sammanfattning : Climate change is an evermore urging existential treat to the human enterprise. Mean temperature and greenhouse gas emissions have in-creased exponentially since the industrial revolution. But solutions are also mushrooming with exponential pace. LÄS MER

  7. 5. Dynamics and Control of Unmanned Spacecraft Rendezvous and Docking

    Master-uppsats, KTH/Farkost och flyg
