  1. 1. Limited angle reconstruction for 2D CT based on machine learning

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Eric Oldgren; Knut Salomonsson; [2023]
    Nyckelord :CT; computed tomography; limited angle; machine learning; limited data; ill posed problem; inverse problem;

    Sammanfattning : The aim of this report is to study how machine learning can be used to reconstruct 2 dimensional computed tomography images from limited angle data. This could be used in a variety of applications where either the space or timeavailable for the CT scan limits the acquired data.In this study, three different types of models are considered.

  3. 2. Dating of fashion plates (1820-1880) using transfer learning : Recognition of the year of origin of fashion plates

    Master-uppsats, Jönköping University/Jönköping AI Lab (JAIL)

    Författare :Magdalena Dobrzańska; [2023]
    Nyckelord :ai; fashion history;

    Sammanfattning : Fashion history is an integral subfield of history as a whole. Fashion plates provide important evidence of what fashion once looked like and as such are a valuable window into the lives of the people in ages past. LÄS MER

  4. 3. Evaluation of the ERA5-Land dataset for estimation of soil moisture in the permafrost region

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Alberta van Gent; [2023]
    Nyckelord :Soil moisture; ERA5-Land; International Soil Moisture Network ISMN ; permafrost region;

    Sammanfattning : The permafrost region covers a vast area of land surface on the northern hemisphere,storing large amounts of carbon. Unfortunately, climate warming leads to permafrostthaw altering the hydrothermal state of permafrost soils. Due to the remoteness of thepermafrost region, access to field measurements is restricted.

  5. 4. PGE Geochemistry and Mineralogy of Dunite, Chromitite, and Laterite Samples from the Acoje Ophiolite Block, Philippines

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Michelle Dossey; [2023]
    Nyckelord :PGM; PGE; laterite; limonite; chromitite; dunite; platinum group minerals; platinum group elements; Acoje; Philippines;

    Sammanfattning : Ni-laterites have the potential to become unconventional ore deposits for platinum group elements (PGE). This study was conducted to determine enrichment trends of PGE as a result of the Ni-laterization process. LÄS MER

  7. 5. Paths forward for Sustainable Maritime Transport : A techno-economic optimization framework for next generation vessels

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Julian Ulrich Hausweiler; [2023]
    Nyckelord :;

    Sammanfattning : Recently, the decarbonization of maritime transport has received increased attention, in order to align with the targets of the Paris Agreement. In 2023, the International Maritime Organization unveiled their revised greenhouse gas strategy with an ambitious target: net-zero emissions by 2050. LÄS MER
