  1. 1. Evaluation of Methods for Sound Source Separation in Audio Recordings Using Machine Learning

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Amanda Gidlöf; [2023]
    Nyckelord :Sound source separation; signal processing; audio processing; speech enhancement; speaker identification; speech separation; speech processing; speaker separation; single channel; multi channel; cocktail party problem; machine learning; neural network; deep learning; deep neural network; convolutional network; dual-path network; filter-and-sum network; recurrent network; beamforming;

    Sammanfattning : Sound source separation is a popular and active research area, especially with modern machine learning techniques. In this thesis, the focus is on single-channel separation of two speakers into individual streams, and specifically considering the case where two speakers are also accompanied by background noise.

  3. 2. Blind Acoustic Feedback Cancellation for an AUV

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Hampus Frick; [2023]
    Nyckelord :acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Sammanfattning : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. LÄS MER

  4. 3. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Adnan Asif Rifat; [2023]
    Nyckelord :Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Sammanfattning : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. LÄS MER

  5. 4. Pilotstudie av källsorterande avloppslösning : Identifiering av systemlösning för källsorterat avloppsavfall i Sydöstra staden i Uppsala

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Linnea Ekblad; [2022]
    Nyckelord :source separating sewage system; urine diversion; anaerobic digestion; wastewater treatment plant; källsorterande avloppssystem; urinsortering; rötning; reningsverk;

    Sammanfattning : Utanför Uppsalas stadskärna planeras det att bygga en ny stadsdel till år 2050, kallad Sydöstra staden. Uppsala kommun vill vara i framkant gällande hållbar stadsplanering och är därför intresserade av att utreda möjligheter till att tillvarata resurser i avloppsvattnet, som ett alternativ till konventionell rening.

  7. 5. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Mehrzad Ghassemi; [2022]
    Nyckelord :Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes. LÄS MER
