  1. 1. Estimating Diffusion Tensor Distributions With Neural Networks

    Master-uppsats, Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Rimaz Nismi; [2024]
    Nyckelord :Diffusion; Magnetic Resonance Imaging; MRI; Neural Networks; Optimal transport; Earth mover s distance; Sinkhorn distance;

    Sammanfattning : Magnetic Resonance Imaging (MRI) is an essential healthcare technology, with diffusion MRI being a specialized technique. Diffusion MRI exploits the inherent diffusion of water molecules within the human body to produce a high-resolution tissue image. An MRI image contains information about a 3D volume in space, composed of 3D units called voxels. LÄS MER

  3. 2. ACCESS TO URBAN COOL AND GREEN SPACES FOR OLD ADULTS IN GOTHENBURG – A GIS-BASED ANALYSIS OF RADIANT HEAT

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Robert Klein; [2023-01-19]
    Nyckelord :urban climate; heat stress; mean radiant temperature; SOLWEIG; urban vegetation; urban planning;

    Sammanfattning : Old adults are particularly vulnerable against heat stress. Considering the ageing society and the projected increase of heat events, planning for heat-resilient urban environments for old adults will become increasingly important. LÄS MER

  4. 3. Förekomst och spridning av hänglavar från äldre skogar till unga tidigare avverkade områden i Västerbottens inland

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Emma Maksimova; [2023]
    Nyckelord :Lichens; Dispersal; Picea abies; Pinus sylvestris; Epiphytic; Hair lichens; Alectoria; Bryoria; Usnea;

    Sammanfattning : The Swedish forestry and the use of clearcutting models has resulted in great losses of older forests in Sweden, resulting in several species being affected negatively. Hair lichens are important organisms that are providing several ecological functions in forest ecosystems and are declining due to being associated with older forests with high continuity. LÄS MER

  5. 4. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Joel Fransson Forsberg; [2023]
    Nyckelord :Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

    Sammanfattning : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. LÄS MER

  7. 5. Artificial Transactional Data Generation for Benchmarking Algorithms

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Veronica Lundgren; [2023]
    Nyckelord :Data Analytics; Synthetic Data; Statistical Distribution; Embedding; Transactional Data;

    Sammanfattning : Modern retailers have been collecting more and more data over the past decades. The increased sizes of collected data have led to higher demand for data analytics expertise tools, which the Umeå-founded company Infobaleen provides. A recurring challenge when developing such tools is the data itself. LÄS MER
