  1. 11. Matematikens utveckling i Sverige fram till 1731

    Författare :Staffan Rodhe; Hans Wallin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; MATEMATIK; Swedenborg; Polhem; Duhre; Klingenstierna; svensk matematikhistoria; serier; oändligt lilla; infinitesimal; oändlighet; kalkyl; Bernoulli; professor; Uppsala; differential; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Sammanfattning : This thesis contains two parts:In the first papers I consider the development of mathematics up till around 1720. I have done a special study of the period between 1710 and 1720, when you could find three Swedes writing about contemporary mathematics, Christopher Polhem, Emanuel Swedenborg and Anders Gabriel Duhre.

  3. 12. The function concept and university mathematics teaching

    Författare :Olov Viirman; Iiris Attorps; Barbara Jaworski; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mathematics; university education; commognitive framework; function concept; discourse; teaching; Matematik; Mathematics;

    Sammanfattning : This thesis concerns the teaching of mathematics at university level, with a particular focus on the teaching of the function concept. The main aim of the thesis is describing and analysing the teaching practices of university mathematics teachers regarding the function concept, and how this concept is constituted through these practices.

  4. 13. On linear graph invariants related to Ramsey and edge numbers : or how I learned to stop worrying and love the alien invasion

    Författare :Oliver Krüger; Jörgen Backelin; Alexander Engström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ramsey number; edge number; minimal Ramsey graph; independence number; clique number; Turán s theorem; crochet pattern; H13-pattern; linear graph invariant; triangle-free graph; Mathematics; matematik;

    Sammanfattning : In this thesis we study the Ramsey numbers, R(l,k), the edge numbers, e(l,k;n) and graphs that are related to these. The edge number e(l,k;n) may be defined as the least natural number m for which all graphs on n vertices and less than m edges either contains a complete subgraph of size l or an independent set of size k.

    Sammanfattning : The main body of this thesis consists of six appended papers.The papers are about the theory of the positive real interpolationwith McMillan degree constraint.In Paper A, a parameterization of the positive real residue interpolantswith McMillan degree constraint is given.

  7. 15. Models for capturing the penetration of a diffusant concentration into rubber : Numerical analysis and simulation

    Författare :Surendra Nepal; Adrian Muntean; Nadja Ray; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transport of diffusants; moving-boundary problem; finite element method; a priori and a posteriori error estimates; random walk method; two-scale coupled system; Matematik; Mathematics;

    Sammanfattning : Understanding the transport of diffusants into rubber plays an important role in forecasting the material's durability. In this regard, we study different models, conduct numerical analysis, and present simulation results that predict the evolution of the penetration front of diffusants. LÄS MER
