  1. 1. Numerical modeling of walls with micro encapsulated PCM

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Karl-Oskar Voutilainen; [2023]
    Nyckelord :PCM; phase change material; COMSOL Multiphysics;

    Sammanfattning : There is a renewed interest to use material as wood to construct large multi-storey buildings in Sweden, but lightweight material tends to increase the indoor temperature fluctuations during days with large changes in outdoor temperature. The problem can be resolved by integrating phase change material (PCM) in the construction. LÄS MER

    Sammanfattning : Reinforcement learning is one of the three main paradigms in machine learning, which is increasingly used as a method to approach scientific problems. In this thesis, we introduce and use reinforcement learning to find the optimal parameters of a numerical solver. LÄS MER

  5. 4. Real-time Optimal Braking for Marine Vessels with Rotating Thrusters

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Sigurlaug Rún Jónsdóttir; [2022]
    Nyckelord :Nonlinear optimization; nonlinear optimal control; numerical optimal control; real-time solution; optimal braking; receding horizon; modeling; ship model; propeller forces; rudder forces; direct multiple shooting method; discretization;

    Sammanfattning : Collision avoidance is an essential component of autonomous shipping. As ships begin to advance towards autonomy, developing an advisory system is one of the first steps. An advisory system with a strong collision avoidance component can help the crew act more quickly and accurately in dangerous situations. LÄS MER

  7. 5. Optimisation of a LOX/Ethanol rocket engine ignition

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Pierre Collard; [2022]
    Nyckelord :;

    Sammanfattning : For more than half a century, humanity has achieved the feat of extracting itself from the earth's atmosphere and sailing into space, broadening the spectrum of knowledge and curiosity. Although space market seemed mastered and stable the arrival of new private players has reorganized the sector through new technological choices. LÄS MER
