  1. 1. Encountering the meeting place : The production of public space in contemporary Swedish planning

    Författare :Christopher Olsson; Mats Lundmark; Ida Andersson; Carina Listerborn; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban planning; public space; spaces of encounter; meeting place; redevelopment projects; the production of space;

    Sammanfattning : A common theme in contemporary Swedish planning discussions is that we no longer meet each other in public spaces. This perceived lack of interpersonal meetings and encounters is said to reinforce the use ofstereotypes and create further distance between differences in the city. LÄS MER

  3. 2. Modeling and electrical characterization of Cu(In,Ga)Se2 and Cu2ZnSnS4 solar cells

    Författare :Christopher Frisk; Charlotte Platzer-Björkman; Jörgen Olsson; Janez Krč; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis, modeling and electrical characterization have been performed on Cu(In,Ga)Se2 (CIGS) and Cu2ZnSnS4 (CZTS) thin film solar cells, with the aim to investigate potential improvements to power conversion efficiency for respective technology. The modeling was primarily done in SCAPS, and current-voltage (J-V), quantum efficiency (QE) and capacitance-voltage (C-V) were the primary characterization methods. LÄS MER

  4. 3. Many-body Problems in the Theory of Stellar Collapse and Neutron Stars

    Författare :Emma Olsson; Bengt Gustafsson; Christopher Pethick; Bengt Friman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; neutron stars; core-collapse supernovae; response functions; Fermi liquids; nuclear matter; neutrino interactions; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik;

    Sammanfattning : When modelling the collapse of massive stars leading to supernova explosions and the cooling of neutron stars, understanding the microphysical processes, such as the interaction of neutrinos within a dense medium are of vital importance. The interaction of neutrinos with nucleons (neutrons and protons) is altered by the presence of the medium, compared to the same process with free nucleons. LÄS MER
