  1. 1. The Winograd Convolution Method

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Alexander Wallén Kiessling; Viktor Svalstedt; [2023]
    Nyckelord :Convolution; Winograd; FFT;

    Sammanfattning : The convolution operation is a powerful tool which is widely used in many disciplines.Lately is has seen much use in the area of computer vision, particularly with convolutionalneural networks. For these use cases, convolutions need to be run repeatedly many timeswhich necessitates specialized hardware. LÄS MER

    Nyckelord :Three-level inverters; over-modulation techniques; space vector modulation; neutral-point voltage balancing; non-uniform Fourier transform; Trenivåväxelriktare; övermodulation; spacevektormodulering; balansering av nollpunktsspänning; olikformig Fouriertransform;

    Sammanfattning : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. LÄS MER

  4. 3. Room Impulse Response Interpolation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Daníel Thor Wilcox; [2023]
    Nyckelord :Virtual Acoustics; Machine Learning; Signal Processing; Room Impulse Response; Virtuell Akustik; Maskininlärning; Signalbehandling; rumsimpulssvar;

    Sammanfattning : In Virtual Reality (VR) systems, the incorporation of acoustics allows for the generation of audio-visual stimuli, facilitating applications in engineering, architecture, and design. The goal of virtual acoustics is to create a realistic sound field in continuous space. LÄS MER

  5. 4. Perceptually meaningful time and frequency resolution in applying dialogue enhancement in noisy environments : Dialogue Enhancement research

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :SUSHANTH PATIL; [2023]
    Nyckelord :Dialogue enhancement; audio signal processing; Fourier transform; time constants; environmental noise analysis; noise compensation; subjective listening test; speech intelligibility; quality of experience; listening effort.; Dialogförbättring; ljudsignalbehandling; Fouriertransform; tid konstanter; miljöbrusanalys; bruskompensation; subjektivt lyssnande test; taluppfattbarhet; upplevelsekvalitet; lyssnaransträngning;

    Sammanfattning : Dialogue Enhancement (DE) is a process used in audio delivery systems to improve the clarity, intelligibility, and overall quality of the spoken dialogue in audio content. It is primarily used when dialogue is masked by music, surrounding noise, or other audio sources. LÄS MER

  7. 5. Ultra Low Frequency Electromagnetic Waves at the Saturn Bow Shock

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Axel Lindberg; Johan Höglund; [2023]
    Nyckelord :;

    Sammanfattning : This project aims to research the characteristics and prevalence of ultra low frequency(ULF) waves at the Saturn bow shock with the help of data collected by the space probe CASSINIwhich was in orbit around the planet from 2004 and 2017. ULF waves have been extensively studiedat Earth but not at Saturn, and by studying this phenomenon at Saturn we may gain a deeperunderstanding of it. LÄS MER
