  1. 1. Exploiting the Overtones in Online Localization of Sound Sources

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :David Sundström; [2022]
    Nyckelord :Multi-pitch estimation; localization; block sparsity; sparse recursive least squares; online estimation; ADMM; adaptive dictionary; Mathematics and Statistics;

    Sammanfattning : Localization of multiple sound sources from a microphone array is a challenging task that has been a research topic for decades. The challenges stem from the diversity of acoustic contexts due to reverberation and disturbances. LÄS MER

  2. 2. PHA-framställning från restströmmar med lösningsmedelsextraktion : En energianalys på PHA-produktion med och utan intern värmeintegrering vid extraktion på torr och våt biomassa

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Fanny Elfving; [2021]
    Nyckelord :PHA; skogsindustriellt avloppsvatten; bioplast; intern värmeintegrering; pinchanslys; CHEMCAD;

    Sammanfattning : Polyhydroxyalkanoater (PHA) är en grupp av polymerer som är biobaserade, biologiskt nedbrytbara och som kan uppvisa varierande fysiokemiska egenskaper. Således har PHA potential att ersätta konventionell och fossilbaserad plast så som polypropylen (PP) och polyetentereftalat (PET). LÄS MER

  3. 3. A Close Look at the Transient Sky in a Neighbouring Galaxy

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Kiran Tikare; [2020]
    Nyckelord :Astrophysical Transients; Optical Transients; Microlensing; Variable Stars; Andromeda Galaxy; Forced Aperture Photometry; Time Domain Astronomy; Sky Survey; Zwicky Transient Facility; Machine Learning; Big Data Science;

    Sammanfattning : Study of the time variable sources and phenomena in Astrophysics provides us with important insights into the stellar evolution, galactic evolution, stellar population studies and cosmological studies such as number density of dark massive objects. Study of these sources and phenomena forms the basis of Time Domain surveys, where the telescopes while scanning the sky regularly for a period of time provides us with positional and temporal data of various Astrophysical sources and phenomena happening in the Universe.

  4. 4. Integrated hydrodynamic and socio-economic damage modelling for assessment of flood risk in large-scale basin : The case study of Lower Chao Phraya River Basin in Thailand

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Phat Pumchawsaun; [2018]
    Nyckelord :Chao Phraya River Basin; flood risk assessment; 2D hydrodynamic model; fully 2D and coupled 1D 2D numerical methods; KULTURisk methodology; depth-damage functions;

    Sammanfattning : Thailand has been often affected by severe flood events over the past century. The 2011’s Thailand Flood Catastrophe was the costliest in country’s history, and it was ranked to be the second most damaging natural hazard in the world in terms of economic losses. LÄS MER

  5. 5. In the eye of the storm : a gendered study on climate change adaptation in small-scale farming in Thái Bình, Vietnam

    Master-uppsats, Lunds universitet/LUCSUS

    Författare :Josephine Ylipää; [2018]
    Nyckelord :gender; climate change adaptation; livelihoods; policy; sustainability science; Vietnam; Social Sciences;

    Sammanfattning : Vietnam is one of the countries in the world that is projected to be most impacted by climate change. Extreme weather events such as storms and floods are predicted to increase with the changing climate. As such, climate change adaptation is crucial, especially for farmers who are relying on vulnerable livelihoods to climate change. LÄS MER
