  1. 1. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Colin Potter; [2023]
    Nyckelord :Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

    Sammanfattning : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

  3. 2. Suppression of Li-ion Battery Fires

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Linfan Cai; [2023]
    Nyckelord :Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

    Sammanfattning : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

  4. 3. Hållbar dagvattenhantering utifrån våtmarkens egenskaper : exemplet Videdal, Malmö

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Maj Lyth; Disa Fredriksson Bratthäll; [2023]
    Nyckelord :våtmark; hållbar dagvattenhantering; dagvattenhantering; skyfall;

    Sammanfattning : Det här examensarbetet fokuserar på två områden som är relevanta för stadens utveckling i ett föränderligt klimat. Det första området handlar om problematiken kring klimatförändringar i förhållande till staden och våtmarken, och det andra lyfter komplexiteten i stadens dagvattenhantering, samt reningen av stadens förorenade dagvatten.

  5. 4. Effects of stratospheric wildfire smoke on ozone depleting substances and ozone levels in the northern midlatitudes

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Författare :Christopher Grüner; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The goal of this project was to examine whether there are correlations between recent wildfires in the northern hemisphere and stratospheric ozone anomalies in the midlatitudes following the creation of ozone depleting substances. To achieve this goal, data from the Aura satellite's Microwave Limb Sounder instrument was used and processed with self-written Python scripts. LÄS MER

  7. 5. Cirkulär ekonomiför plastavfall : Hantering av akrylplast som ett steg mot ett merhållbart samhälle

    Kandidat-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Emma Bondemark; Josefin Heinevik; [2022]
    Nyckelord :Acrylic plastic; Circular economy; Lightning manufacturer; Plastic waste; Plexiglas; PMMA; Polymetylmetakrylat; Recycling Reuse; Akrylplast; Belysningstillverkare; Cirkulär ekonomi; Plastavfall; Plexiglas; PMMA; Polymetylmetakrylat; Återvinning;

    Sammanfattning : Purpose – The aim of the study is to investigate the possibilities for circular economy in acrylicplastic in the lighting industry. To answer the purpose, it was broken down into two researchquestions: [1] What characterizes the handling of acrylic plastic waste by lighting manufacturers? [2] How can lighting manufacturers achieve a more circular handling of acrylic plastic waste? Method – To be able to answer the research questions, a case study was conducted at acompany active in the lighting industry. LÄS MER
