  1. 16. Analys och minskning av effektförlusterna i en borstlös likströmsmotor med vektorstyrning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Lider Xavier Garcia Parrales; [2023]
    Nyckelord :Effektförluster Borstlös likströmsmotor BLDC Vectorstyrning Field-oriented Control FOC Blockkommutering Block commutation MTPA; Technology and Engineering;

    Sammanfattning : This report addresses power losses in an electric motor arising from various sources. The choice of motor control strategy can decrease efficiency if not implemented correctly or if the motor model in the control loop is overly simplified. LÄS MER

  4. 18. Optimisation of warehouse for second-hand items using Machine Learning

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

    Författare :Simon Osnes; [2023]
    Nyckelord :Second-hand; Machine Learning; Data Analysis; Feature Selection; Clustering; K-Means; Second-hand; Maskininlärning; Dataanalys; Urval av Attributer; Klustring; K-Means;

    Sammanfattning : Warehouse management and organisation often use the popularity of items to assign placements in the warehouse and predict sales. However, when dealing with only unique second-hand items another solution is needed. LÄS MER

  5. 19. När platserna inte räcker till : En kvalitativ studie om gatekeeping inom dansvärlden

    Kandidat-uppsats, Södertörns högskola/Sociologi

    Författare :Linn Yttersjö; [2023]
    Nyckelord :dance world; dance residency; selection; gatekeeping; uncertainty; uncertainty reduction; conventions; dansvärld; dansresidens; urval; gatekeeping; osäkerhet; osäkerhetsreducering; konventioner;

    Sammanfattning : The aim of this study is to widen the sociological knowledge about how gatekeepers make selections, in contexts characterized by uncertainty. This is examined through the dance world as empirical case, based on the question “How do gatekeepers orientate themselves in the uncertainty that characterizes decision-making around which dance artists should be assigned dance residencies?”.

  7. 20. Machine learning algorithm for generation and consumption forecasting in an electrical network

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

    Författare :Isac Hutchings; Joel Oyola; [2023]
    Nyckelord :;

    Sammanfattning : Power generation and consumption are directly affected by weather, and the weather variables are fluctuating, which means that generation and consumption also fluctuate. These fluctuations can damage equipment or cause other problems in an electrical network. LÄS MER
