  1. 26. Mathematical Tools Applied in Computational Electromagnetics for a Biomedical Application and Antenna Analysis

    Författare :Farid Monsefi; Sergei Silvestrov; Magnus Otterskog; Linus Carlsson; Jean-Pierre Bérenger; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : To ensure a high level of safety and reliability of electronic/electric systems EMC (electromagnetic compatibility) tests together with computational techniques are used. In this thesis, mathematical modeling and computational electromagnetics are applied to mainly two case studies. LÄS MER

  3. 27. Speaking of Geometry : A study of geometry textbooks and literature on geometry instruction for elementary and lower secondary levels in Sweden, 1905-1962, with a special focus on professional debates

  4. 28. To explore and verify in mathematics

    Författare :Tomas Bergqvist; Hans Wallin; Johan Lithner; Morten Blomhøj; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Explorations; mathematical reasoning; empirical investigations; graphing calculators; conjectures.; Subject didactics; Ämnesdidaktik; MATHEMATICS; MATEMATIK; didactics of mathematics; matematikdidaktik;

    Sammanfattning : This dissertation consists of four articles and a summary. The main focus of the studies is students' explorations in upper secondary school mathematics. In the first study the central research question was to find out if the students could learn something difficult by using the graphing calculator. LÄS MER

  7. 30. Some modes of convergence and their application to homogenization and optimal composites design

    Författare :Anders Holmbom; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Homogenization; two-scale convergence; MATHEMATICS; MATEMATIK; Mathematics;

    Sammanfattning : In this thesis, we develop, extend, apply, and discuss a number of methods for the study of limits of sequences of functions and operators. The connection between the notion of two-scale convergence and more general concepts of convergence is investigated and some alternative classes of admissible test functions are characterized. LÄS MER
