  1. 1. Generalized super-resolution of 4D Flow MRI : extending capabilities using ensemble learning

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Adam Hjalmarsson; Leon Ericsson; [2023]
    Nyckelord :4D Flow MRI; Ensemble learning; Super-resolution; Machine learning; Neural networks; 4DFlowNet;

    Sammanfattning : 4D Flow Magnet Resonance Imaging (4D Flow MRI) is a novel non-invasive technique for imaging of cardiovascular blood flow. However, when utilized as a stand-alone analysis method, 4D Flow MRI has certain limitations including limited spatial resolution and noise artefacts, motivating the application of dedicated post-processing tools.

  3. 2. Beyond Conservation: Unlocking livelihoods, empowering communities : The case of Mamirauá

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Alejandra Leon Lavandera; [2023]
    Nyckelord :CBNRM; local livelihoods; participatory approach; protected area;

    Sammanfattning : The spread of Community-based Natural Resources Management (CBNRM) programs can be attributed to the failure of top-down approaches and the development of more equitable governance strategies. A CBNRM approach seeks to fulfill dual objectives by balancing environmental conservation goals and local livelihood opportunities. LÄS MER
