  1. 1. Mathematical Reasoning : In physics and real-life context

    Detta är en avhandling från Göteborg : Chalmers University of Technology and University of Gothenburg

    Författare :Helena Johansson; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Creative mathematical reasoning; Descriptive statistics; Differential item functioning; Figurative context; Imitative reasoning; Mathematical Reasoning Requirements; Mathematics tasks; National tests; Physics tasks; Real-life context; T-test; Upper secondary school;

    Sammanfattning : This thesis is a compilation of four papers in which mathematical reasoning is examined in various contexts, in which mathematics is an integral part. It is known from previous studies that a focus on rote learning and procedural mathematical reasoning hamper students’ learning of mathematics. LÄS MER

  2. 2. Mathematical Reasoning in Physics Tests - Requirements, Relations, Dependence

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Helena Johansson; Göteborgs universitet.; Gothenburg University.; Göteborgs universitet.; Gothenburg University.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical reasoning; imitative reasoning; creative mathematical reasoning; physics tests; physics tasks; upper secondary school; Mantel-Haenszel procedure.; Mantel-Haenszel procedure;

    Sammanfattning : By analysing and expanding upon mathematical reasoning requirements in physics tests, this licentiate thesis aims to contribute to the research studying how students’ knowledge in mathematics influence their learning of physics. A sample of physics tests from the Swedish National Test Bank in Physics was used as data, together with information of upper secondary students’ scores and grades on the tests. LÄS MER

  3. 3. Depletion and decline curve analysis in crude oil production

    Detta är en avhandling från Uppsala : Global Energy Systems, Department for Physics and Astronomy, Uppsala University

    Författare :Mikael Höök; Uppsala universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; depletion rate; decline curve analysis; crude oil production; NATURAL SCIENCES Earth sciences Other earth sciences; NATURVETENSKAP Geovetenskap Övrig geovetenskap; NATURAL SCIENCES Physics Other physics Mathematical physics; NATURVETENSKAP Fysik Övrig fysik Matematisk fysik; TECHNOLOGY Engineering physics Other engineering physics; TEKNIKVETENSKAP Teknisk fysik Övrig teknisk fysik; Physics with specialization in Global Energy Resources; Fysik med inriktning mot globala energiresurser;

    Sammanfattning : Oil is the black blood that runs through the veins of the modern global energy system. While being the dominant source of energy, oil has also brought wealth and power to the western world. Future supply for oil is unsure or even expected to decrease due to limitations imposed by peak oil. Energy is fundamental to all parts of society. LÄS MER

  4. 4. On string integrability A journey through the two-dimensional hidden symmetries in the AdS/CFT dualities

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Valentina Giangreco Marotta Puletti; Uppsala universitet.; [2009]

    Sammanfattning : One of the main topics in the modern String Theory are the conjectured string/gauge (AdS/CFT) dualities. Proving such conjectures is extremely difficult since the gauge and string theory perturbative regimes do not overlap. In this perspective, the discovery of infinitely many conserved charges, i.e. LÄS MER

  5. 5. Solving the quantum scattering problem for systems of two and three charged particles

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scattering theory; three body scattering; NATURAL SCIENCES Physics Atomic and molecular physics; NATURVETENSKAP Fysik Atom- och molekylfysik; NATURAL SCIENCES Physics Other physics Mathematical physics; NATURVETENSKAP Fysik Övrig fysik Matematisk fysik; fysik; Physics;

    Sammanfattning : A rigorous formalism for solving the Coulomb scattering problem is presented in this thesis. The approach is based on splitting the interaction potential into a finite-range part and a long-range tail part. In this representation the scattering problem can be reformulated to one which is suitable for applying exterior complex scaling. LÄS MER
