  1. 1. A speech therapy support tool based on spectral density adjustment

    University essay from Lunds universitet/Matematisk statistik

    Author : Erik Stålberg; Artur Lidström; [2021]
    Keywords : speech therapy; spectral estimation; fundamental frequency estimation; FIR filter design; Mathematics and Statistics; Medicine and Health Sciences;

    Abstract : The purpose of this work is to expand the toolbox of speech language pathologists and give them the ability to redesign a patient’s voice to a healthier sounding one, thereby giving the patient a target voice to strive towards. A modified voice is generated by applying a finite impulse response (FIR) filter, altering the spectrum of the patient’s voice. READ MORE

  3. 2. Classifying stock returns using high-frequency fundamental factors and convolutional neural networks

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Denis Dvinskikh; Axel Kotnik; [2021]
    Keywords : convolutional neural networks; fundamental factors; technical indicators; high-frequency stock prices; classification;

    Abstract : We evaluate the usefulness of high-frequency fundamental factor exposures of five US equities, between 2013 and 2017, as features for classifying and predicting the binary movements of the same stocks in 5-minute and 20-day intervals using Convolutional Neural Networks (CNN). After plotting rolling factor betas (Market, HML, SMB) and the close price of a given stock in the corresponding intervals, these time series are converted into images as Gramian Angular Difference Fields (GADF) and then concatenated to be fed to the CNN as input.

  4. 3. Evaluation of an automated formant estimation procedure with optimized formant ceiling

    University essay from Stockholms universitet/Institutionen för lingvistik

    Author : Anna Ericsson; [2020]
    Keywords : Evaluation; Formant estimation; Formant ceiling optimization; High fundamental frequency; Formantmätningsmetod; Formanttaksoptimering; Hög grundton; Utvärdering;

    Abstract : This study evaluates an automated formant estimation procedure designed to adapt to speakers and variations in speech. The adaption is achieved by using the formant ceiling with the least variation (in combined estimates of F1 and F2) as the optimal ceiling. READ MORE

  5. 4. Interharmonic Analysis of Sustainable Energy Sources and Loads : Comparing two signal processing methods for estimation of interharmonics

    University essay from Högskolan Dalarna/Energiteknik

    Author : Isabelle Löfgren; [2020]
    Keywords : interharmonics; short time Fourier transform; desynchronized processing technique; sliding-window ESPRIT; power quality; signal processing;

    Abstract : In this report, studies on interharmonics from three different measurement sites are performed. The first site is a wind park with three turbines, where the measurements are performed at the point of common coupling of these three. READ MORE

  6. 5. Method for coupling modulatedscattered light from free flyinginsects to harmonics and theirrelative phases

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk statistik

    Author : Martin Patricks; Ludvig Anderberg; [2020]
    Keywords : frequency estimation; phase estimation; matched phase reassignment; entomologic lidar; modulation spectroscopy; scattered light; Technology and Engineering;

    Abstract : Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. READ MORE
