  1. 21. Small scale VTOL aircraft using only one lift-producing motor : A study of lift capacity for a Vertical Take-Off and Landing capable aircraft

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

    Författare :Daniel Milenkovic; [2023]
    Nyckelord :Aircraft; VTOL; EDF; Mechatronics; Ardupilot; Luftfarkost; VTOL; EDF; Mekatronik; Ardupilot;

    Sammanfattning : The usage of unmanned aerial vehicles in applications such as terrain mapping and surveillance is proliferating in the modern world. This project aims to investigate the feasibility, in terms of payload capacity and stability, of small scale winged aircraft that have the ability to lift and land vertically, while also being able to transition to normal forward flight using wings for primary lift.

  3. 22. Hardware Subsystem Proposal of an Off-Vehicle Battery Analyzer from a Charging/Discharging Perspective

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Rinor Gashi; Tim Johansson; [2023]
    Nyckelord :battery electric vehicles; power conversion module; off-vehicle battery packs;

    Sammanfattning : Electric Vehicles (EVs) are seen as one of the solutions to some of the world’s global current problems, such as global warming and air pollution, due to non-existent operational emissions and increased efficiency. There are multiple types of EVs, one of them being Battery Electric Vehicles (BEVs) which in most cases utilizes a Li-Ion battery pack as energy storage. LÄS MER

  4. 23. Optimization of an energy system in rural Thailand

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

    Författare :Axel Lund; Mattias Malmberg; [2023]

    Sammanfattning : By 2020, Thailand ensured 100% electricity access to its 72 million inhabitants. This was partly done by promoting off-grid energy systems in rural areas instead of using costly grid extensions. LÄS MER

  5. 24. Investigation of the Swedish study aid system : Significance of potential system misuse

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Företagsekonomi

    Författare :Povilas Keniausis; Dmitri Kolyarchik; [2023]
    Nyckelord :CSN; economic student aid; Swedish study aid; student loan effects.;

    Sammanfattning : Since the introduction of CSN (Centrala studiestödsnämnden/Swedish Board of StudentFinance), the amount of students entering higher education has drastically increased. Along-term investigation has been conducted by the Swedish Financial Department(Finansdepartementet) in order to identify potential ways of improvement of the Swedishstudy aid system. LÄS MER
