  1. 1. The rubber hand illusion effectiveness on body ownership induced by self-produced movements : A Meta-Analysis

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Malin Brundin; [2020]
    Nyckelord :rubber hand illusion; body ownership; sense of agency; motor control mechanisms; meta-analysis;

    Sammanfattning : Body ownership can be studied via the rubber hand illusion (RHI), in which an artificial limb can be perceived as belonging to oneself. In the so-called moving RHI paradigm, both body ownership and sense of agency, induced by self-produced movements, can be investigated. LÄS MER

  2. 2. Utvärdering av roterande borstlösfrekvensomformare tillspårledningar

    M1-uppsats, KTH/Hälsoinformatik och logistik; KTH/Hälsoinformatik och logistik

    Författare :Leith Aldahan; Ivan Kudoori; [2019]
    Nyckelord :Frequency converter; induction motor; track circuit; asynchronous motor; railway signaling; reluctance motor; RAMS; Frekvensomformare; asynkronmotor; spårledning; asynkronmaskin; signalsystem; reluktansmotor; RAMS;

    Sammanfattning : Spårledningar används inom tunnelbanan för att visa tågets position samt bestämma tågets hastighet genom att bryta spänningsamplituden i signalen vid olika frekvenser. Frekvensen till spårledningen fås från en roterande frekvensomformare. I dagens anläggning används roterande frekvensomformare med borstar. LÄS MER

  3. 3. Field Current Control for the Damping of Rotor Oscillations and for the Alternative Start of Synchronous Machines : Further Innovative Applications of Field Current Active Control besides UMP-Compensation

    Master-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Roberto Felicetti; [2018]
    Nyckelord :asynchronous start; current control; damping bars; damper winding; d-axis; q-axis; hunting; natural frequency; Park s reference frame; rotor back-EMF; rotor oscillations; synchronous motor;

    Sammanfattning : The possibility to save energy in synchronous machines operation by dismissing d-axis damping bars and surrogating them with active excitation current control in sectored field winding is proved. In particular a way to recover the energy of rotor oscillations during power regulation is shown by means of a studycase generator whereas a self-starting machine is analytically and numerically designed in view of its next construction and test.

  4. 4. Simulation of 3ph induction motor in Matlab with Direct and Soft starting methods.

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Mohamad Moulham Abboud; [2015]
    Nyckelord :3ph-induction motor; Matlab; Model; Simulation; Direct starting; Soft starting;

    Sammanfattning : Asynchronous machines are considered nowadays the most commonly used electrical machines, which are mainly used as electrical induction motors. Starting the induction motor is the most important and dangerous step. LÄS MER

  5. 5. Motion controlled cleaning of large tanks

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

    Författare :Mattis Wahlby; [2013]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Reduction of the cleaning time is an important issue for companies using large tanks. A common solution is a stationary pipe going into the tank with a cleaning nozzle mounted on the end. Today the spray pattern of most cleaning systems is fixed. LÄS MER
