  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

  3. 2. The sound of rage : the perceived impact of misophonia on daily life and relationships

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Silvia Estela Morales Gutiérrez; [2023]
    Keywords : misophonia; emotional dysregulation; auditory stimuli; decreased sound tolerance; sound sensitivity; aversive sounds; select sound sensitivity syndrome;

    Abstract : Misophonia is a condition characterized by a strong physiological, emotional, and behaviouralresponse to specific auditory stimuli, which have a significant negative impact on the wellbeingof affected individuals. The present investigation focuses on emotional dysregulation, which arises due to the triggering of specific auditory stimuli. READ MORE

  4. 3. Wireless Beehive Monitoring : Using edge computing and TinyML to classify sounds

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Mattias Holmgren; Elias Holmér; [2022]
    Keywords : TinyML; beehives; honey bees; supervised machine learning; Internet of Things IoT ; power consumption optimization;

    Abstract : As an essential and indispensable contributor to pollinating the world's crops and plants, the honey bee is key to the sustainability of humans' and our ecosystems' continued survival. Following in the footsteps of the companies TietoEvry and Beelabs project, this report also works towards monitoring bees during their daily activities. READ MORE

  5. 4. Compare Accuracy of Alternative Methods for Sound Classification on Environmental Sounds of Similar Characteristics

    University essay from Stockholms universitet/Statistiska institutionen

    Author : Olov Rudberg; [2022]
    Keywords : Machine Learning; Algorithms; Neural Networks; Computer Vision; Image Recognition; Environmental Sound Classification; Data Augmentation;

    Abstract : Artificial neural networks have in the last decade been a vital tool in image recognition, signal processing and speech recognition. Because of these networks' ability to be highly flexible, they suit a vast amount of different data. This flexible attribute is very sought for within the field of environmental sound classification.
