  1. 1. Machine Learning model applied to Reactor Dynamics

    Master-uppsats, KTH/Fysik

    Författare :Dionysios Dimitrios Nikitopoulos; [2023]
    Nyckelord :Master Thesis; Machine Learning; stability; Energy distribution profiles; Prediction; frequency; decay ratio; Data processing; POLCA-T; Pytorch; testing data; RMSE. ii;

    Sammanfattning : This project’s idea revolved around utilizing the most recent techniques in MachineLearning, Neural Networks, and Data processing to construct a model to be used asa tool to determine stability during core design work. This goal will be achieved bycollecting distribution profiles describing the core state from different steady statesin five burn-up cycles in a reactor to serve as the dataset for training the model.

  3. 2. S-MARL: An Algorithm for Single-To-Multi-Agent Reinforcement Learning : Case Study: Formula 1 Race Strategies

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marinaro Davide; [2023]
    Nyckelord :Reinforcement Learning; Single-to-Multi-Agent; Learning Stability; Exploration-Exploitation trade-off; Race Strategy Optimization; Förstärkningsinlärning; Från en till flera agenter; Stabilitet vid inlärning; Utforskning-exploatering; Optimering av tävlingsstrategier;

    Sammanfattning : A Multi-Agent System is a group of autonomous, intelligent, interacting agents sharing an environment that they observe through sensors, and upon which they act with actuators. The behaviors of these agents can be either defined upfront by programmers or learned by trial-and-error resorting to Reinforcement Learning. LÄS MER

  4. 3. Modelling and Simulation of Hydrogen Electrolyzers for Power System Applications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Javier Vinuelas Ferrando; [2023]
    Nyckelord :;

    Sammanfattning : The rapid increase in the share of intermittent renewables in the energy mix is exacerbating the complexity of the grid stability. To facilitate the inclusion of these green technologies and achieve the climate targets set by the EU, the generation and storage of hydrogen through electrolysis may be crucial. LÄS MER

  5. 4. Tunnelbyggande vid partiell bergtäckning : En fallstudie av Nacka Centrums tunnelbanestation

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Elias Rydhäll; Anton Bergholm; [2023]
    Nyckelord :;

    Sammanfattning : I samband med urbanisering av städer ökar omfattningen av byggda delar och antalet pågående byggnadsprojekt. Den ökade bebyggelsen i kombination med samhällets intresse leder till att projekt utförs med minskad möjlighet att välja lämplig plats. LÄS MER

  7. 5. Investigation on stability of Knowledge Based Subset Construction in Multi-Agent Games

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :Gustaf Johansson; Gustaf Bergmark; [2022]
    Nyckelord :Multi-Agent games; Imperfect information; Strategy synthesis; Structural conditions; Fleragentsspel; Ofullständig information; Strategisyntes; Strukturella villkor;

    Sammanfattning : Many real life problems can be modelled using multi-agent games played on finite graphs. When an agent cannot differentiate between game states, for example when a robot operates with a broken sensor, the game is classified as a game of imperfect information. LÄS MER
