  1. 1. Efficient Music Thumbnailing for Genre Classification

    University essay from KTH/Matematisk statistik

    Author : Adam Skärbo Jonsson; [2022]
    Keywords : Music thumbnailing; Music genre classification; Machine learning; Deep learning; Bidirectional recurrent neural network; RNN; Musikgenreklassificering; Maskininlärning; Djupinlärning; RNN;

    Abstract : For music genre classification purposes, the importance of an intelligent and content-based selection of audio samples has been mostly overlooked. One common approach toward representative results is to select samples at predetermined locations. This is done to avoid analysis of the full audio during classification. READ MORE

  3. 2. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Henrik Johansson; [2022]
    Keywords : Auxiliary Power Supply; HVDC; Inductive Power Supply; High Voltage Insulation; High-Frequency Transformer; Hjälpkraftsförsörjning; HVDC; Induktiv Kraftförsörjning; Högspänningsisolation; Högfrekvenstransformator;

    Abstract : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. READ MORE

  4. 3. Parameter Study of Arc Squeezing DC Breaker : The impact of the geometry on counter force, pressure, and arc voltage

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Johanna Olsson; [2022]
    Keywords : Arc squeezing; DC breaker; Polymer ablation; Pressure measurement; Ljusbågssläckning; DC brytare; Polymerablation; Tryckmätning;

    Abstract : The sustainable future in our already electrified world includes solar power generation, battery storage, and electric vehicles all which requires DC systems. DC breakers play a key role in operation and protection within the DC system. READ MORE

  5. 4. Measuring Respiratory Frequency Using Optronics and Computer Vision

    University essay from Linköpings universitet/Datorseende

    Author : Per Antonsson; Jesper Johansson; [2021]
    Keywords : Computer Vision; Optical Flow; Motion Vectors; Respiratory Frequency; Signal Processing;

    Abstract : This thesis investigates the development and use of software to measure respiratory frequency on cows using optronics and computer vision. It examines mainly two different strategies of image and signal processing and their performances for different input qualities. READ MORE
