  1. 21. En experimentell studie om VVC & KVC-värmepump för att motverka legionella

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

    Författare :Anton Julin Wallén; Arijan Ghassemloi; Marvina Mukamisha; [2023]
    Nyckelord :;

    Sammanfattning : Denna studie har som syfte att främst motverka legionellabakterier i tappvattnet som kan bildas och växa om tappvattnets temperatur ligger inom riskområdet på 20–50 °C. Inandning av legionellabakterier kan leda till pontiacfeber eller den dödliga sjukdomen legionella. LÄS MER

  3. 22. Radio Environment Compensation in a Narrowband IoT Positioning System : Using Radio Signal Metrics Between Stationary Devices

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

    Författare :Elin Berglund; [2023]
    Nyckelord :Positioning; IoT; machine learning; range estimation; Positionering; IoT; maskininlärning; avståndsuppskattning;

    Sammanfattning : The Internet of Things (IoT) has emerged as a powerful tool for meeting our need to collect information about and interact with our environments. One important aspect of this technology is positioning which imposes requirements on both the energy consumption and the arrangement of the systems. LÄS MER

  4. 23. Swedish Offshore Wind : Modelling development pathways to commercial viability

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

    Författare :Siddharth Iyer; [2023]
    Nyckelord :;

    Sammanfattning : Offshore wind will play an important role in Sweden’s fossil-free energy future. Although Sweden has many offshore wind farms in the planning and approval stages, few projects have been built, and little public research on which offshore wind areas and individual farms are most economically viable.

  5. 24. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Sara Lenman; Sofia Blaad; [2023]
    Nyckelord :Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Sammanfattning : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. LÄS MER

  7. 25. Assessment of hydrogen supply chain for transport sector of Sweden

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

    Författare :José Maria Soares Rodrigues; [2023]
    Nyckelord :Hydrogen; Hydrogen Supply Chain; Elecrolysis; 2030; Sweden; Electricity prices; MILP; Optimization; Vätgas; Vätgassupplykedja; Elektrolys; 2030; Sverige; Elpriser; MILP; Optimering;

    Sammanfattning : Fuel cell electric vehicles, powered by hydrogen are an enticing alternative to fossil-fuel vehicles in order to reduce greenhouse gas emissions and consequently accomplish the environmental targets set to tackle the environmental crisis. It is crucial to develop the appropriate infrastructure if the FCEVs are to be successfully accepted as an alternative to fossil-fuel vehicles. LÄS MER
