  1. 1. Evaluation of the challenges and opportunities of Vehicle-to-Grid technology and the potential revenue streams for BEV fleet owners and aggregators

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

    Författare :Lukas Strandberg; Madeleine Sandberg; [2023]
    Nyckelord :Vehicle-to-Grid; Grid flexibility; Capacity markets; Barriers; Fordon-till-nätteknologi; Elnätsflexibilitet; Kapacitetsmarknader; Barriärer;

    Sammanfattning : The increasing amount of renewable energy being connected to the power grid, and the intermittent nature of these resources, calls for increased grid flexibility to ensure operational safety and stability. An effective solution to address this need could be through wider implementation of various energy storage technologies. LÄS MER

  3. 2. Crystallinity of Sputtered TiO2 Thin Films: a Study of the Heating and Plasma Influence on the Growth

    Master-uppsats,

    Författare :oussama ezzaher; [2023]
    Nyckelord :;

    Sammanfattning : AbstractHigh-Power Impulse Magnetron Sputtering (HIPIMS) of TiO2 thin films enhances their photocatalyticproperties compared to the films prepared by standard sputtering methods, especially when no substrateheating is employed. With no heating, the coatings present an amorphous structure that benefits from theionization of the sputtered flux granted by HiPIMS, with respect to their photocatalytic performance. LÄS MER

  4. 3. Development of a Compact Drive System for Total Artificial Heart

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Hossin Bakhtiari; [2023]
    Nyckelord :Total Artificial Heart; Drive System; Miniaturization; Electric Motor; Motor Performance Evaluation; Motor Selection; Totalt artificiellt hjärta; drivsystem; miniatyrisering; elektrisk motor; motorprestanda utvärdering; motor-urval;

    Sammanfattning : Over eight decades of research into total artificial hearts (TAHs) has significantly contributed  to saving end-stage heart failure patients. However, at the current stage of development TAHs have several limitations, one of them being their bulkiness. LÄS MER

  5. 4. Elektrifiering av hydraulsystem : En studie kring lämpliga växlar och motorer för grävmaskinstillbehöret tiltrotatorn

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Hampus Lundgren; [2023]
    Nyckelord :cykloidväxel; elektrifiering; hydraulik; hållfasthet; mekanik; tiltrotator; cycloid drive; electrification; hydraulic; strength; mechanics; tiltrotator;

    Sammanfattning : Today’s electric excavators uses standard hydraulics to control external tools. To increase the degree of freedom the excavator is equipped with a tiltrotator placed between arm and bucket. LÄS MER

  7. 5. Reaction Wheel Control System for a Self-balancing Bike : Reaction wheel based control mechanism for a small scale prototype bike

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

    Författare :Reman Soryani; [2023]
    Nyckelord :Mechatronics; Control Theory; Reaction Wheel; PID Controller; Robotics; Mekatronik; Reglerteknik; Mekanik; PID reglering; Robotik;

    Sammanfattning : In this thesis, the design of a self balancing prototype bike with a reaction wheel as balancing mechanism will be investigated. Bikes are inherently unstable systems, that dynamically resemble an inverted pendulum at a stand still. LÄS MER
