  1. 1. Traces of Iron Age activities at Kullen - A New Synthesis

    Master-uppsats, Lunds universitet/Arkeologi

    Författare :Karolina Jacobsen; [2023]
    Nyckelord :iron age; Scania; kullaberg; kullen; social structures; GIS; spatial analysis; assemblage theory; affordance theory; entanglement theory; power; resources; older remains; social roles; sites; functions; landscape archaeology; social; culture; activities; cultural landscapes; historical legacies; History and Archaeology;

    Sammanfattning : Kullen has had a huge gap in knowledge about the Iron Age period. This thesis offers a new synthesis to close this gap in knowledge of the Iron Age period in the region. The aim of this study was to gain more knowledge about the Iron Age and the activities during this period in the areas. LÄS MER

  3. 2. What limits the luminosity of red supergiants?

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Eric Svensson; [2023]
    Nyckelord :Stellar evolution; Red supergiants; Red giants; Luminosity; Binary stars; Binary star systems; Binary star interactions; Binary stellar evolution; Humphreys-Davidson limit; Upper luminosity limit; BSE; Population synthesis; Simulations; M31; LMC; SMC; Metallicity; Mass transfer; Merging; Physics and Astronomy;

    Sammanfattning : The observed upper limit of the luminosity of red supergiants, often called the Humphreys-Davidson limit, has recently been shown to be independent of metallicity and to not be explainable by single star evolution – findings that both contradict established ideas of the origins of the limit. It is now known that the vast majority of stars with sufficient mass to possibly evolve into red supergiants above the limit interact with companion stars at some point during their lives. LÄS MER

  4. 3. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Salim Charkas; [2023]
    Nyckelord :Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

    Sammanfattning : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

  5. 4. Grönska i stadens små rum : omgestaltning av en lastgata till gröna vistelseytor på Norrmalm, Stockholm

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural Development

    Författare :Elsa Drettner; [2023]
    Nyckelord :fickparker; förtätning; urban grönska; sociala mötesplatser; stockholms arkitekturpolicy;

    Sammanfattning : Sverige är ett av Europas mest glesbefolkade länder. Samtidigt står delar av Stockholm för de absolut mest tätbefolkade områdena i Europa. Stockholms innerstad har en genomsnittlig befolkningstäthet på över 9000 invånare per kvadratkilometer, och en del av Södermalm utgör den sjätte mest tätbefolkade kvadratkilometern i hela Europa.

  7. 5. Exploring Normalizing Flow Modifications for Improved Model Expressivity

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marcel Juschak; [2023]
    Nyckelord :Normalizing Flows; Motion Synthesis; Invertible Neural Networks; Glow; MoGlow; Maximum Likelihood Estimation; Generative models; normaliserande flöden; rörelsesyntes; inverterbara neurala nätverk; Glow; MoGlow; maximum likelihood-skattning generativa modeller;

    Sammanfattning : Normalizing flows represent a class of generative models that exhibit a number of attractive properties, but do not always achieve state-of-the-art performance when it comes to perceived naturalness of generated samples. To improve the quality of generated samples, this thesis examines methods to enhance the expressivity of discrete-time normalizing flow models and thus their ability to capture different aspects of the data.
