  2. 16. Some new results in homogenization of flow in porous media with mixed boundary condition

    Author : Elena Miroshnikova; Andrey Piatnitski; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : The present thesis is devoted to derivation of Darcy’s Law for incompressible Newtonian fluid in perforated domains by means of homogenization techniques.The problem of describing flow in porous media occurs in the study of various physical phenomena such as filtration in sandy soils, blood circulation in capillaries etc. READ MORE

  4. 17. Estimates for Hardy-type integral operators in weighted Lebesgue spaces

    Author : Larissa Arendarenko; Massimo Lanza de Cristoforis; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : This PhD thesis deals with the theory of Hardy-type inequalities in a new situation, namely when the classical Hardy operator is replaced by a more general operator with a kernel. The kernels we consider belong to the new classes $\mathcal{O}^+_n$ and $\mathcal{O}^-_n$, $n=0,1,... READ MORE

  5. 18. Perceptions of mathematics in preschool: "-Now we have a way of talking about the mathematics that we can work with"

    Author : Maria Johansson; Birgit Brandt; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics Education; Matematik och lärande;

    Abstract : The overarching question for this thesis is what is preschool mathematics? This question is examined using different points of views or different perspectives such as the children’s, the preschool teachers and the researchers. The foundation for this thesis is seven articles, two single author articles and five co-authored articles. READ MORE

  6. 19. Strong Cosmic Censorship and Cosmic No-Hair in spacetimes with symmetries

    Author : Katharina Maria Radermacher; Hans Ringström; James Isenberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cosmic Censorship; Cosmic No-Hair; Big Bang; symmetry; Bianchi; T2-symmetry; Gowdy; general relativity; cosmology; late time; initial time; asymptotic behaviour; perfect fluid; scalar field; Einstein equations; Mathematics; Matematik;

    Abstract : This thesis consists of three articles investigating the asymptotic behaviour of cosmological spacetimes with symmetries arising in Mathematical General Relativity.In Paper A and B, we consider spacetimes with Bianchi symmetry and where the matter model is that of a perfect fluid.

  7. 20. Pedagogic practice between tradition and renewal : A study of the new mathematics curriculum in Mozambique

    Author : Balbina Mutemba; Candia Morgan; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics Education; Matematik och lärande;

    Abstract : The new school mathematics curriculum in Mozambique, introduced in 2008, is partly competency-based and it advocates a more student-centred pedagogy. The most salient innovative features are the incorporation of mathematical competencies related to the development of students’ reasoning skills, including argumentation, justification and analytical thinking, and the use of heuristic or inductive methods that promote meaningful students’ participation.
