  1. 1. Opto-vibrational coupling in molecular solar thermal storage materials: Electronic structure calculations and neural-networkbased analysis Giannis Kostaras Degree project

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Giannis Kostaras; [2021-01-26]
    Nyckelord :;

    Sammanfattning : Molecular solar thermal storage materials are proposed as a clean, renewable energysolution for a world with ever increasing energy needs. Norbornadiene is anorganic compound suitable for molecular solar thermal storage systems. LÄS MER

  2. 2. Development of a Nordic BWR plant model in APROS and design of a power controller using the control rods

    Master-uppsats, KTH/Fysik

    Författare :Jonathan Al-Ani; [2021]
    Nyckelord :APROS; Dynamic process simulation; System code; Nuclear reactor; nuclear power; BWR; Boiling Water Reactor; closed cycle; steam cycle; one-dimensional flow; Westinghouse; control rods; APROS; Dynamisk processimulering; Beräkningsmodell; Kärnkraft; BWR; Kokvattenreaktor; ångcykel; en-dimensionell flödesmodell; Westinghouse; kontrollstavar;

    Sammanfattning : In this master thesis an input-model of a Nordic BWR power plant has been developed in APROS. The plant model contains key systems and major thermohydraulic components of the steam cycle, including I&C systems (i.e. power, pressure, level and flow controls). LÄS MER

  3. 3. The Changing Character of Mars’ Bow Shock

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

    Författare :Sara Östman; [2021]
    Nyckelord :Bow shock; Space plasma physics; Mars;

    Sammanfattning : The aim of the project is to investigate the characteristics and causes of two different types of bow shocks at Mars. We define Type 1 as an undefined, drawn out ramp, and Type 2 as a shorter duration ramp that has clearer characteristics and behaves more like a step increase in the magnetic field. LÄS MER

  4. 4. Evaluation of In-Silico Labeling for Live Cell Imaging

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

    Författare :Elsa Sörman Paulsson; [2021]
    Nyckelord :Deep learning; Machine Learning; Image analysis; CNN; cell; live cell imaging; supervised learning; AI; artificial intelligence; sartorius;

    Sammanfattning : Today new drugs are tested on cell cultures in wells to minimize time, cost, andanimal testing. The cells are studied using microscopy in different ways and fluorescentprobes are used to study finer details than the light microscopy can observe.This is an invasive method, so instead of molecular analysis, imaging can be used.

  5. 5. Application of Deep Q-learning for Vision Control on Atari Environments

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Jim Öhman; [2021]
    Nyckelord :Reinforcement learning; Atari 2600; Deep Q-learning; Myopic Agents; Vision Control; Physics and Astronomy;

    Sammanfattning : The success of Reinforcement Learning (RL) has mostly been in artificial domains, with only some successful real-world applications. One of the reasons being that most real-world domains fail to satisfy a set of assumptions of RL theory. LÄS MER
