  1. 6. On the statistics and practical application of the reassignment method for Gabor spectrograms

    University essay from Lunds universitet/Matematisk statistik

    Author : Erik. M Månsson; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : The reassignment method is a technique for improving the concentration of signals in spectrograms and other time-frequency representations (TFR). It achieves this by displacing the points in a TFR according to the reassignment vector for every point. READ MORE

  3. 7. Unbiased pitch detection and phase estimation in entomological lidar

    University essay from Lunds universitet/Matematisk statistik

    Author : Johan Fogelmark; [2019]
    Keywords : Entomological lidar; wing beat frequency estimation; phas; Mathematics and Statistics;

    Abstract : Good insect monitoring is important for both disease vector control and e?cient usage of pesticides in farming. Entomological lidar has been proven useful for detecting and monitoring insects. For every insect that transit the laser beam a backscatter signal containing species-specific information is obtained.

  4. 8. Maximum Inverter AC Current Prediction Based on Junction Temperature Calculation

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

    Author : Shuyu Ou; [2019]
    Keywords : IGBT; Inverter; Junction temperature; Current Limiter; IGBT; Växelriktare; Övergångstemperatur; Strömbegränsare;

    Abstract : Semiconductor devices are widely used in the automotive industry, and they are key components of the inverter and the converter in an electric vehicle. Thus, the concern of protecting the inverter and the converter from damaging operation has been raised. The junction temperature is one of the main considerations. READ MORE

  5. 9. An exploration of the current state-of-the-art in automatic music transcription - with proposed improvements using machine learning

    University essay from Lunds universitet/Matematisk statistik

    Author : Joel Torby; [2018]
    Keywords : Music transcription; music annotation; fundamental frequency estimation; machine learning; neural networks; mirex; Mathematics and Statistics;

    Abstract : The research field of automatic music transcription has vastly grown during the 21st century, where the goal is to transcribe a polyphonic music signal into annotated sheet music. Within this field, the subproblem of fundamental frequency estimation in a piece of music is a difficult problem, e.g. READ MORE

  6. 10. Vibration Analysis for Speed Estimation of Wheeled Indoor Vehicles

    University essay from Linköpings universitet/Reglerteknik

    Author : Rasmus Vilhelmsson; [2017]
    Keywords : ;

    Abstract : In this thesis speed estimation of wheeled indoor vehicles based on vibrationsin the wheels is studied. Suitable applications include localization on wheeledindoor equipment, where wheel speed sensors are impractical or cannot be installed. READ MORE
