  1. 1. Symmetries and conservation laws

    Author : Raisa Khamitova; Börje Nilsson; Claes Jougréus; Maria Luz Gandarias; Växjö universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; conservation law; Noether s theorem; Lie group analysis; Lie-Bäcklund transformations; basis of conservation laws; formal Lagrangian; self-adjoint equation; quasi-selfadjoint; equation; nonlocal conservation law; Mathematical physics; Matematisk fysik; Conservation law; Noether’s theorem; quasi-self-adjoint equation;

    Abstract : Conservation laws play an important role in science. The aim of this thesis is to provide an overview and develop new methods for constructing conservation laws using Lie group theory. The derivation of conservation laws for invariant variational problems is based on Noether’s theorem. READ MORE

  2. 2. Uncertainty Quantification and Numerical Methods for Conservation Laws

    Author : Per Pettersson; Jan Nordström; Gianluca Iaccarino; Gunilla Kreiss; Rémi Abgrall; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; polynomial chaos; stochastic Galerkin methods; conservation laws; hyperbolic problems; finite difference methods; finite volume methods; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : Conservation laws with uncertain initial and boundary conditions are approximated using a generalized polynomial chaos expansion approach where the solution is represented as a generalized Fourier series of stochastic basis functions, e.g. orthogonal polynomials or wavelets.

  3. 3. Numerical ice sheet modeling : Forward and inverse problems

    Author : Gong Cheng; Lina von Sydow; Per Lötstedt; Nina Kirchner; Irina Tezaur; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; ice sheet modeling; finite element method; grounding line migration; inverse problems; adjoint method; Scientific Computing; Beräkningsvetenskap;

    Abstract : Ice sheets have strong influence on the climate system. Numerical simulation provides a mathematical tool to study the ice dynamics in the past and to predict their contribution to climate change in the future. Large scale ice sheets behave as incompressible non-Newtonian fluid. READ MORE

  4. 4. In a Man´s World : Tolkninger av lovbrudd gjort i langtransportens yrkeskontekst

    Author : Vanja Lundgren Sørli; Henrik Tham; Eva Tiby; Kjersti Ericsson; Stockholms universitet; []
    Keywords : structures; gender; masculinity; normalization; Key words: Long-distance trucking; occupational crime; techniques of neutralization; ; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : Criminological studies have shown that economical and/or occupational crimes are committed within all examined trades and occupations. This is also a fact in the gendered occupational context the Norwegian and Swedish long-distance trucking trade constitutes. READ MORE

  5. 5. Two sides of the coin - rights and duties : the interface between environmental law and Saami law based on a comparison with Aoteoaroa/New Zealand and Canada
