  1. 21. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Henry Wittler; [2023-11-29]
    Nyckelord :;

    Sammanfattning : Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we investigate by simulation the artifacts on reconstruction when noise are present in the measurement. LÄS MER

  3. 22. Bläckborttagning från ben med hjälp av geler En kvantitativ studie för bläckborttagning på björnbäcken och björnkranium från Naturhistoriska riksmuseet

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Engla Nordin; [2023-11-07]
    Nyckelord :Conservation; reversibility; bones; FTIR; nanogels; hydrogels; ink.;

    Sammanfattning : This bachelor's thesis has investigated four different hydrogels loaded in different solvents efficiency to remove unknown ink from four pelvic bones and one skull from five bear individuals that belongs to The Swedish Museum of Natural History. The experimental part of the thesis consists of an FTIR analysis together with microscopy and macroscopy analysis of the ink on the bear skeletons, as well as some tests of different gel-solvent combinations on a moose skull.

  4. 23. Unlock those closed doors

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Giulia Gualandri; [2023-10-18]
    Nyckelord :Heritage Conservation; Communication; Public outreach; Public engagement;

    Sammanfattning : The present work aims to investigate the current situation regarding the conservation profession and the communication to the public through outreach initiatives, especially from the point of view of the conservators. In the latest decades outreach and communication have been taking a preponderant role within the profession of conservation, causing changes in the daily tasks of conservators and new demands in terms of skills which professionals need to acquire.

  5. 24. Constructing a civilized wilderness. An intersectional discourse analysis of the Sierra Club 1893-1910

    Kandidat-uppsats,

    Författare :Eleonor Ivdal; [2023-10-05]
    Nyckelord :the Sierra Club; intersectional theory; discourse analysis; civilization; American wilderness; national park movement; gender; class; race; ethnicity;

    Sammanfattning : This study investigates if and how the Sierra Club adapted complex and contradictory rationalizations to legitimize their authority in wilderness and civilization. The study aims thereby to enhance our understanding of the origin narrative of the American preservation and conservation movement at the turn of the twentieth century which depicted white male heroes as discoverers and protectors of a pristine wilderness.

  7. 25. Automatic Semantic Role Labelling (SRL) in Swedish

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Lucy Yang Buhr; [2023-10-05]
    Nyckelord :Semantic role labelling; SRL; transfer learning; multi-task learning; multilingual transfer; T5; mT5;

    Sammanfattning : In this paper, using deep learning networks, the first end-to-end semantic role labelling model (SRL) has been developed for Swedish texts. This Swedish SRL model can, with a given Swedish sentence, perform trigger identification, frame classification and argument extraction tasks automatically in a series. LÄS MER
