  2. 12. Digital Signal Characterization for Seizure Detection Using Frequency Domain Analysis

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

    Author : Jing Li; [2021]
    Keywords : Fourier Transform; Wavelet Transform; EEG and ECG Anomaly Detection; Approximate Entropy; Hellinger Distance; Long Short- Term Memory; Fourier Transform; Wavelet Transform; EEG och ECG Anomalidetektion; Approximativ Entropi; Hellinger Distans; Lång Korttidsminne;

    Abstract : Nowadays, a significant proportion of the population in the world is affected by cerebral diseases like epilepsy. In this study, frequency domain features of electroencephalography (EEG) signals were studied and analyzed, with a view being able to detect epileptic seizures more easily. READ MORE

  3. 13. Door closing sound quality related to door sealing stiffness

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Riccardo Derton; [2021]
    Keywords : Door Closing Sound Quality; Customer’s Perspective; Psychoacoustics; Acoustic Analysis; Wavelet Analysis; Artificial Head; Door Closing Motion; Door Seals; Door Sealing Stiffness; Stiffness Analysis; Ljudkvalitet vid dörrstängning; Kundperspektiv; Psykoakustik; Akustisk analys; Wavelet analys; Konstgjort huvud; Dörrstängningsrörelse; Dörrtätningar; Styvhet i dörrtätningar; Styvhetsanalys;

    Abstract : The door closing action is a recurrent situation when using a vehicle, and its sound is therefore a common sensation, which would elicit pleasant feelings. Sensory pleasantness is an important aspect in terms of customer’s perspective, and it can be a contributing factor when deciding to buy or not a specific vehicle. READ MORE

  4. 14. Statistics and machine learning for classification of emotional and semantic content of EEG

    University essay from Lunds universitet/Teknisk matematik (CI); Lunds universitet/Institutionen för reglerteknik

    Author : David Ohlin; Oskar Keding; [2021]
    Keywords : Technology and Engineering;

    Abstract : Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. READ MORE

  5. 15. The Discrete Wavelet Transform

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Wirén Anton; [2021]
    Keywords : Wavelet theory; multiresolution analysis; image processing.;

    Abstract : In this thesis we will explore the theory behind wavelets. The main focus is on the discrete wavelet transform, although to reach this goal we will also introduce the discrete Fourier transform as it allow us to derive important properties related to wavelet theory, such as the multiresolution analysis.
