    Författare :Marina Pakola; Antonia Arab; [2022]
    Nyckelord :Smart control of electricity usage; optimization; mixed-integer linear programming MILP ; electricity price forecasting; load forecasting; storage systems in private households; electricity costs in Sweden;

    Sammanfattning : High electricity prices have become the title of several news articles recently in Sweden and the prices have experienced large sudden fluctuations during certain periods. In this thesis work, a smart control model for the electricity usage in three different households has been developed with the main purpose to minimize the electricity cost. LÄS MER

  3. 7. Comparative life cycle assessment of two desiccant wheel dehumidifiers with industrial application

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

    Författare :Astrid Ortis; [2022]
    Nyckelord :Desiccant wheel dehumidifier; adsorption dehumidification; life cycle assessment LCA ; EU Taxonomy; Rotorsorptionsavfuktare; luftavfuktning; livscykelanalys LCA ; EU taxonomi;

    Sammanfattning : Humans spend around 80 percent of their lifetime indoors. The humidity level plays an essential part in indoor climate, both in non-industrial applications, such as thermal comfort, and industrial ones. Dehumidification is a technology in the field of thermal comfort and indoor climate to control humidity levels. LÄS MER

    Nyckelord :BLDC; PMSM; 6 step; FOC; Clarke; Motor; Park; PWM; Rotor; SVPWM;

    Sammanfattning : Fossil-fuel vehicles are one of the main causes of CO2 emissions nowadays. As we are moving toward cleaner environment electrification of vehicles are becoming more and more popular. With the environment in mind, the recent improvement in battery technology and electronics has drawn a lot of attention to Brushless DC or BLDC  motors. LÄS MER

  5. 9. Research and Testing of an Electromechanical solution for Vibration Assisted Drilling of Aerospace Materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Jonathan Nordenholm; [2020]
    Nyckelord :vibration; drilling; chips; aerospace; advanced drilling unit;

    Sammanfattning : This thesis considers vibration drilling in aerospace materials. The tolerances of the drilled holes in aerospace industry are very low since hole quality is an important factor. Conventional methods of drilling create long ribbon formed chips that increases the heat formation and decreases the hole quality. LÄS MER
