  2. 1. On minimal triangle-free Ramsey graphs

    Author : Oliver Krüger; Jörgen Backelin; Klas Markström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A graph G is called a minimal Ramsey (3, k; n)-graph if it has the least amount of edges, e(3, k; n), possible given that G is triangle-free, has independence number α(G) < k an has n vertices. The numbers e(3, k; n) and the minimalRamsey graphs are directly related to the Ramsey numbers R(3, k). READ MORE

  4. 2. Robust intersection of hexahedral meshes and triangle meshes with applications in finite volume methods

    Author : Frida Svelander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triangle-hex intersection; overlapping triangles; degenerate mesh; volume fraction; area fraction; cut cell; conjugated heat transfer.; triangle-hex intersection;

    Abstract : The topic of this thesis is the intersection of a structured hexahedral grid and one or more triangle meshes. The interest in the problem has arisen in connection with a finite volume method for simulation of conjugated heat transfer. READ MORE

  5. 3. Making transformation happen : Institutional entrepreneurship and boundary management in the Coral Triangle

    Author : Franciska Rosen; Per Olsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This licentiate thesis sets out to investigate the dynamics of transformative change in social-ecological systems. That is, how large-scale sustainability transitions can be initiated and purposefully navigated. READ MORE

  6. 4. Reef Futures : Exploring the dynamics of transformative change in marine social-ecological systems

    Author : Franciska von Heland; Per Olsson; Beatrice Crona; Marja Spierenburg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transformative change; marine governance; multi-stakeholder collaboration; multi-level governance; institutional entrepreneurship; boundary work; narratives; Coral Triangle; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : The thesis explores issues relating to transformative change in the context of marine governance in the Coral Triangle, and the effects of such change processes on policy, stakeholder relations and management activities. Paper 1 studies how change-oriented actors (institutional entrepreneurs) operating at the international level can introduce and purposefully navigate large-scalechange processes. READ MORE

  7. 5. Supporting Learning and Teaching of Chemistry in the Undergraduate Classroom

    Author : Ilana A. Manneh; Karim Hamza; Carl-Johan Rundgren; Lars Eriksson; Ingo Eilks; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; undergraduate chemistry education; learning and teaching processes; didactic triangle; chemical bonding; tutor-student interaction; practical epistemology analysis; continuity; progression; purposes; naturvetenskapsämnenas didaktik; Science Education;

    Abstract : There is agreement in research about the need to find better ways of teaching chemistry to enhance students’ understanding. This thesis aims to contribute to the understanding of how we better support teaching and learning of undergraduate chemistry to make it meaningful and intelligible for students from the outset.
