    Författare :Kristina Tryselius; Lennart Andersson; Thomas Denk; Mattias Kärrholm; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; space; virtual geography; ontology of becoming; geophilosophy; actor-network theory; Deleuze; Latour; the virtual; postulate; virtuell geografi; tillblivelseontologi; geofilosofi; aktör-nätverksteori; Deleuze; Latour; det virtuella; postulat; rum; Human geography; Kulturgeografi; Kulturgeografi; Human Geography;

    Sammanfattning : How is space conceptualized? The question is central to subject theory in human geography. In the present dissertation, this issue is actualized in discussions of the virtual, space, and an ontology of becoming. LÄS MER

  3. 2. Plasticity Driven Damage and Void Growth

    Författare :Mattias Olsson; Kärnfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; Thermal engineering; applied thermodynamics; vibration and acoustic engineering; vacuum technology; hydraulics; void growth; Mechanical engineering; damage evolution; elasto-plasticity; thermodynamics;

    Sammanfattning : Plasticity induced damage evolution is considered using a thermodynamical approach. Different postulates on how to include the effects of damage in the constitutive equations have been studied. The results reveal that a mapping, similar to that of the stress, of both the kinematic and isotropic hardening variables is to be preferred. LÄS MER

  4. 3. Pulp chemistry of sulphide froth flotation

    Författare :Bertil Pålsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The pulp chemistry of chalcopyrite, galena and sphalerite is analyzed theoretically, with computer-aided modelling, and practically with ion chromatography. Ion chromatography is used for analyzing the inorganic and organic anion chemistry of sulphide flotation. LÄS MER

  5. 4. Biases in Visual Selective Attention : Trait Anxious Individuals Avert Their Gaze From Unpleasant Stimuli

    Författare :Jean-Christophe Rohner; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; eye-movements; attentional biases; Anxiety; attention; Psykologi;

    Sammanfattning : Cognitive models of anxiety postulate that anxious individuals are inclined to pay more attention to negative than to positive emotional visual stimuli. The main aim of the present dissertation was to test this prediction, employing a measure of the direction of gaze. LÄS MER

  7. 5. Classification of Normal Discrete Kinetic Models

    Författare :Mirela Christina Vinerean; Alexander Bobylev; Mirela Vinerean-Bernhoff; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kinetic theory; discrete kinetic velocity models; conservation laws; MATHEMATICS; MATEMATIK; Matematik; Mathematics;

    Sammanfattning : “In many interesting papers on discrete velocity models (DVMs), authors postulate from the beginning that the finite velocity space with "good" properties is given and only after this step they study the Discrete Boltzmann Equation. Contrary to this approach, our aim is not to study the equation, but to discuss all possible choices of finite phase spaces (sets) satisfying this type of "good" restrictions. LÄS MER
