  2. 21. Analysis of the phase space, asymptotic behavior and stability for heavy symmetric top and tippe top

    Author : Markus Sköldstam; Stefan Rauch-Wojciechowski; Torkel Glad; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; symmetric top; tippe top; vertical rotation; truncated sphere; asymptotic trajectories; MATHEMATICS; MATEMATIK;

    Abstract : In this thesis we analyze the phase of the heavy symmetric top and the tippe top. These tops are two examples of physical systems for which the usefulness of integrals of motion and invariant manifolds, in phase space picture analysis, can be illustratedIn the case of the heavy symmetric top, simplified proofs of stability of the vertical rotation have been perpetuated by successive textbooks during the last century.

  4. 22. Explorations of University Physics in Abstract Contexts : From de Sitter Space to Learning Space

    Author : Daniel Domert; Cedric Linder; Ulf Danielsson; Duncan Fraser; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; phenomenography; cosmology; de Sitter space; quantum mechanics; conceptual understanding; epistemology; physics equations; Fysik; Physics; Fysik; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Abstract : This is a thesis which contributes to research in two different fields: theoretical physics and physics education research. The common link between these two research areas is that both involve explorations of abstract physics and mathematical representations, but from different perspectives. READ MORE

  5. 23. Inference in Temporal Graphical Models

    Author : Jonas Hallgren; Timo Koski; Dubhashi Devdatt; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : This thesis develops mathematical tools used to model and forecast different economic phenomena. The primary starting point is the temporal graphical model. Four main topics, all with applications in finance, are studied. READ MORE

  6. 24. Hadronic Interactions at High and Low Energies

    Author : Marius Utheim; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Phenomenology; Hadronic rescattering; Heavy ions; Exotic hadrons; Cosmic rays;

    Abstract : In the past, development of the PYTHIA event generator has mainly concentrated on the physics of proton–proton collisions at high energies, as this is the most important case to modern high energy physics experiments. However, there are situations where more generic beam configurations are relevant. READ MORE

  7. 25. Black-Hole Universe

    Author : Irina Galstyan; Kjell Rosquist; Ingemar Bengtsson; Sören Holst; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : In this thesis, we have constructed new analytical solutions for initial data of the Einstein equations. Such solutions are valuable for gaining a better understanding of problems involving strong gravitational and/or electromagnetic interactions in general relativity. READ MORE
