    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. Development of methods and software for rapid quality control in fluoroscopy

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Majid Khosamadi; [2021]
    Nyckelord :;

    Sammanfattning : Background: Fluoroscopy is a common imaging technique which uses X-ray to derive a real time imaging of patient anatomy to determine diagnosis and positioning of patients for interventional procedures. It is therefore important that the fluoroscopy systems maintain their performance. LÄS MER

  5. 5. Flambehandling som metod för ökad vätbarhet av polyolefina plaster

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

    Författare :Filiph Sandberg; [2021]
    Nyckelord :flambehandling; venturi;

    Sammanfattning : Liquid, pressurized natural gas in fiberglass tanks is becoming an increasingly common source of energy for the transport sector. The complete product consists of a plastic tank enclosed in fiberglass to achieve the required strength needed. LÄS MER
