1. A speech therapy support tool based on spectral density adjustment
University essay from Lunds universitet/Matematisk statistikAbstract : 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

2. Classifying stock returns using high-frequency fundamental factors and convolutional neural networks
University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomiAbstract : 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.

3. Evaluation of an automated formant estimation procedure with optimized formant ceiling
University essay from Stockholms universitet/Institutionen för lingvistikAbstract : 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

4. Interharmonic Analysis of Sustainable Energy Sources and Loads : Comparing two signal processing methods for estimation of interharmonics
University essay from Högskolan Dalarna/EnergiteknikAbstract : 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

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 statistikAbstract : 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
