    Sammanfattning : This study explores the performance of porous Paptic paper materials composed of a mixture of softwood and lyocell fibers. The investigation involves laboratory experiments and numerical simulations to analyse the impact of various parameters on the paper's characteristics. LÄS MER

  4. 3. Designing k-Space Filters to Improve Spatiotemporal Resolution with Sector-Wise Golden Angle (SWIG)

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Jonas Ström Seez; [2022]
    Nyckelord :Cardiovascular Magnetic Resonance Imaging CMR ; k-Space Filter; Sector Wise Golden-angle SWIG ; Kardiovaskulär Magnetisk Resonans Tomografi CMR ; k-rumsfilter; Sektorsvis Gyllene Vinkel SWIG ;

    Sammanfattning : The aim of this thesis is to design and evaluate k-space weighting filters for simultaneously improving the spatial and temporal resolution of cardiovascular MRI, with the ultimate goal of improving the accuracy of quantitative flow measurements, which are important for diagnosis and follow-up of heart dysfunction. Two different k-space filters were implemented and evaluated retrospectively to already acquired data. LÄS MER

  5. 4. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Julia Cavell; [2022]
    Nyckelord :;

    Sammanfattning : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.
