  1. 1. Vibroacoustic Analysis of an OLTC Diverter Switch for Condition Monitoring : Time frequency analysis with Fourier and wavelet transform in combination with multivariate logistic regression for condition monitoring of OLTC diverter switch

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Simon Persson; [2023]
    Keywords : Wavelet transform; CWT; logistic regression; machine learning; ML; vibroacoustic analysis; time frequency analysis; tap changer; diverter switch; power transformer; classification; prediction; condition; vibrations; state prediction; Hitachi Energy;

    Abstract : Vibrations are everywhere around us all the time and we often recognise them as sounds that we can hear and analyse with our brain. In this thesis, data that has been gathered from a diverter switch (DS) in a controlled environment, is analysed. READ MORE

  4. 3. Frequency analysis of whisker movement in mouse models of Parkinson's disease

    University essay from KTH/Datavetenskap

    Author : Vilhelm Hellmér; André Fredriksen; [2022]
    Keywords : ;

    Abstract : As the life expectancy in the world increases, so does the prevalence of many age-related diseases. One such disease is Parkinson’s disease (PD) which is a neurological disease that affects patients through tremors, muscle stiffness and has an inhibitory effect on movement. READ MORE

  5. 4. Transfer learning applied to a deep learning system for cardiac abnormality classification in electrocardiograms

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

    Author : Adrian Campoy Rodriguez; [2022]

    Abstract : Cardiovascular diseases are a leading cause of death globally. Early diagnosis and treatment is of prime importance to prevent or mitigate health complications. Electrocardiogram (ECG) is a standard test modality used for early diagnosis of arrhythmias. The standard ECG uses 12 leads (i. READ MORE

  6. 5. Towards a Data-Driven Approach to Ground-Fault Location in Distribution Power System using Artificial Neural Network

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Antoine Dupuis; [2021]
    Keywords : Ground-Fault Location; Distribution power System; Artificial Neural Network; Machine Learning; Distributed Generation; Wavelet Transform;

    Abstract : Motivated by the need for less polluting energy production, the recent increase in renewable electricity production is reshaping classical power systems. Initially unidirectional and constant power flow becomes multi-directional and dynamic. As one of the many consequences, classical power system fault location methods might become outdated. READ MORE
