  1. 1. Spin-Glass Behaviour in Ordered Solids

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Erik Karpelin; [2023]
    Nyckelord :spin-glass; self-induced; variation; Edwards-Andersson; glassy;

    Sammanfattning : The spin-glass is a peculiar magnetic phase, exhibiting non-trivial dynamics at low temperatures, characterized by an continuously evolving state without long-range order. The behavior requires some degree of disorder to occur, often in the way of impurities or random exchange energy between the spins. LÄS MER

  3. 2. The impact of multicultural festivals on women's empowerment in Uppsala : A case of immigrant women

    Master-uppsats, Södertörns högskola/Institutionen för samhällsvetenskaper

    Författare :Ehmeli Dzifa Amengor; [2023]
    Nyckelord :immigrant women; multicultural festivals; women’s empowerment;

    Sammanfattning : Empowerment is a process or a mechanism of individuals, organizations and communitiesacquiring control over their lives (Rappaport (1987), and there is a sustained effort by nationsand the international communities across the globe in search of pragmatic agendas and policyframework in achieving women’s empowerment. The purpose of this study was to understandthe experiences of immigrant women who participate in multicultural festivals, and how suchexperiences impact their empowerment. LÄS MER

  4. 3. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Hamish Keay; [2023]
    Nyckelord :Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Sammanfattning : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. LÄS MER

  5. 4. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Siri Alva Berge; [2023]
    Nyckelord :magnetocaloric effect; atomistic spin dynamics; monte carlo; antiferromagnet; neodymium; noncollinear magnetism;

    Sammanfattning : The magnetocaloric effect (MCE) is the temperature change in a magnetic material due to a change in an applied magnetic field. How the MCE behaves in different magnetic materials and at different phase transitions is fundamental to understand. LÄS MER

  7. 5. Automating Water Orientation in Neutron Crystallography using Convolutional Neural Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Simon Bakran; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : One important aspect of determining the functionality of proteins is to find the direction of the dipole moment of surrounding water molecules. This is equivalent to finding the position of the hydrogen in water, however with the current atomistic model building tools this is a tedious and time-consuming task. LÄS MER
