  1. 11. Ion dynamics and structure of collisionless shocks in space

    Författare :Andreas Johlander; Andris Vaivads; Robert F. Wimmer-Schweingruber; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Sammanfattning : Shock waves form when supersonic flows encounter an obstacle. Like in regular gases, shock waves can form in a plasma - a gas of electrically charged particles. Shock waves in plasmas where collisions between particles are very rare are referred to as collisionless shock waves. LÄS MER

  3. 12. School choice, space and the geography of marketization- Analyses of educational restructuring in upper secondary education in Sweden

    Författare :Anna Maria Fjellman; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; school choice; school market; marketization; space; equity; quasi-market; differentiation; spatial justice;

    Sammanfattning : The main aim of the dissertation is to investigate, analyze and create a research-based understanding of the spatialities of the Swedish school choice in upper secondary education using a socio-spatial framework. The dissertation is comprised of three empirical studies based on six cohorts of register data from The Gothenburg Longitudinal Database. LÄS MER

  4. 13. Solar Wind Dynamics within The Atmosphere of comet 67P/Churyumov-Gerasimenko

    Författare :Etienne Behar; Hans Nilsson; Thomas E. Cravens; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : In this thesis, we explore the dynamics of the solar wind as it perme-ates and flows through a tenuous cometary atmosphere, with a focuson the interaction observed at comet 67P/Churyumov–Gerasimenko.Seven comets had already been visited by nine different probes when the European spacecraft Rosetta reached comet Churyumov–Gerasimenko in August 2014.

  5. 14. Computational modeling of complex flow : Doctoral thesis at Chalmers University of Technology

    Författare :Johan Hoffman; Claes Johnson; Ragnar Winter; Chalmers; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we consider the following aspects of computational modeling of complex flows: (i) subgrid modeling, (ii) stability, (iii) a posteriori error estimation, and (iv) computational platform. We develop a framework for adaptivity and error control for multiscale problems, in particular for turbulent flow, based on a posteriori error estimates. LÄS MER

  7. 15. Temporalitet i visuell kultur : Om samtidens heterokrona estetiker

    Författare :Ann-Louise Sandahl; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; temporality; heterochrony; chronoscopy; anthropocene; the long now; timescapes; space of flows; space of places; environmental humanities; temporalitet; heterokroni; kronoskopi; antropocen; det långa nuet; flödesrum; platsrum; miljöhumaniora; temporality; heterochrony; chronoscopy; anthropocene; the long now; timescapes; space of flows; space of places; environmental humanities.;

    Sammanfattning : In contemporary society temporalities in different scales coexist, cooperate and collide. Clock time serves as a main reference for time, although a lot of processes have nothing to do with clock time and can’t be measured by its scales. LÄS MER
