  1. 1. Deep Perceptual Loss and Similarity

    Författare :Gustav Grund Pihlgren; Marcus Liwicki; Fredrik Sandin; Hugo Larochelle; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Image Similarity; Perceptual Similarity; Perceptual Loss; Deep Features; Deep Learning; Machine Learning; Maskininlärning;

    Sammanfattning : This thesis investigates deep perceptual loss and (deep perceptual) similarity; methods for computing loss and similarity for images as the distance between the deep features extracted from neural networks. The primary contributions of the thesis consist of (i) aggregating much of the existing research on deep perceptual loss and similarity, and (ii) presenting novel research into understanding and improving the methods.

  2. 2. Temperature and heat losses simulation in core and winding of a power transformer

    Författare :Kourosh Mousavi Takami; Mahmoudi Jafar; Lennart Harnefors; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Transformer; Losses; Simulation; Temperature; Calculation; Electric power engineering; Elkraftteknik; elektronik; Electronics;

    Sammanfattning : Simulering av temperatur och värmeförluster i kärna och lindning för en högspänningstransformator “... Ett ljus som lyser dubbelt så starkt, varar hälften så länge …”, i analogi med ljuset så kan transformatorer köras med överlast inom vissa gränser, men med följden att livslängden blir kortare.

  3. 3. Energy Efficiency of an Electric Vehicle Propulsion Inverter Using Various Semiconductor Technologies

    Författare :Ali Rabiei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drive cycles; Vehicle applications; Dc-link; Electric machines; Loss calculation; Power electronics; Silicon carbide; Current vector control; Nonlinear Optimization; Energy efficiency;

    Sammanfattning : In this Licentiate thesis, various solutions to improve the efficiency in the electrical vehicledrive drive line such as in the propulsion inverter and in the electric machine, are proposedand their benefits are quantified from an energy efficiency point of view. The efficiencyanalysis is based on modeling of a power electronics inverter, an electric machine and abattery in various drive cycles of an electric vehicle. LÄS MER

    Sammanfattning : Damages are the only remedy in the law of intellectual property (IP) through which rightsholders may recover compensation following an infringement of their rights. Because the intellectual property framework’s main goal is to protect rightsholders’ investments, one might believe that damages would serve an important role in the majority of infringement cases.

    Sammanfattning : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. LÄS MER
