  1. 1. Quality enhancement of time-resolved computed tomography scans with cycleGAN

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

    Författare :Johannes Stubbe; [2023]
    Nyckelord :carbon fibers; carbon fibres; microfibers; tomography; deep learning; cycleGAN; time-resolved tomography; Physics and Astronomy;

    Sammanfattning : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. LÄS MER

  3. 2. Greenhouse gas emissions and carbon burial in a small pond

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

    Författare :Maria Carlson; [2023]
    Nyckelord :Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

    Sammanfattning : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. LÄS MER

  4. 3. Climate effects of managed boreal forests : combining effects from carbon balance and albedo

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Anna Valeria Requardt; [2023]
    Nyckelord :Remotely Sensed Albedo; Age-Albedo pattern; C-flux Radiative Forcing; Boreal Forests Climate Effect;

    Sammanfattning : Boreal forests are considered as a global carbon (C) sink and are utilized for climate-change mitigation. Judging the climate impact of a forest solely on its C balance might leave an incomplete picture, since forest-climate feedbacks are also caused by various other biophysical and biogeochemical processes, e.g., albedo effects.

  5. 4. The Effects of Clear-Cutting a Hemiboreal Forest on Local CO2 Fluxes in Norunda, Sweden

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

    Författare :Mads Carlsen; [2023]
    Nyckelord :CO2 flux; Clear-cutting; Coniferous forest; Flux footprint; Sustainable forestry; Earth and Environmental Sciences;

    Sammanfattning : As CO2 builds up in the atmosphere causing global climate change (IPCC, 2022) trees have become an international symbol of combatting this, and for good reason. Trees take up CO2 which as a result combats these changes, and when these trees are cut down fewer individuals remain to take up the CO2 that we humans emit (Chapin et al., 2011). LÄS MER

  7. 5. Utvärdering av V2G : Lönsamhet och miljöpåverkan med N(D)-baserad degraderingsmodell för elbilsbatterier

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Sjögren Johan; [2023]
    Nyckelord :V2G; batteri; batteridegradering; N D ; energi;

    Sammanfattning : The transition from combustion engine vehicles to electric vehicles (EV) is an important step in achieving a carbon neutral society, but poses future difficulties in energy production. This is an issue in sustaining sufficient net energy, as well as providing sufficient power during hours of high demand. LÄS MER
