  1. 1. Topological and geometrical methods in data analysis

    Författare :Oliver Gäfvert; Sandra di Rocco; Henry Schenck; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multiparameter persistent homology; computational algebraic geometry; algorithms; complexity; Mathematics; Matematik;

    Sammanfattning : This thesis concerns two related data analysis pipelines, using topological and geometrical methods respectively, to extract relevant information. The first pipeline, referred to as the topological data analysis (TDA) pipeline, constructs a filtered simplicial complex on a given data set in order to describe its shape. LÄS MER

  2. 2. Causal Combinatorics : Edges of the Characteristic Imset Polytopes

    Författare :Petter Restadh; Svante Linusson; Liam Solus; James Cussens; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : Explaining data in a concise and efficient manner has become increasingly important in today's society. This thesis pertains to the problem of finding causal links within data, and how that can be done from a mathematical perspective. Using the framework of graphical models has several advantages, from interpretability to efficiency. LÄS MER

  3. 3. 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

  4. 4. Kollegialt lärande i matematik : Ett verksamhetsteoretiskt perspektiv

    Författare :Frida Harvey; Per Nilsson; Anna Teledahl; Inger Eriksson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Activity system; Contradictions; Cultural Historical Activity Theory; PLCs in mathematics; mathematics education; Kollegialt lärande; kollegialt lärande i matematik; matematikdidaktik; motsättningar; verksamhetssystem; verksamhetsteori;

    Sammanfattning : In the last decade, Professional Learning Communities (PLCs) are increasingly used as models for teachers’ joint efforts in developing their teaching. The overall aim of this licentiate thesis is to expand the knowledge of PLCs in mathematics, by deepening the understanding of aspects that influence the establishment, organization, and implementation of PLCs in mathematics.

  5. 5. On numbers badly approximable by q-adic rationals

    Författare :Johan Nilsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Number theory; Symbolic dynamics; Combinatorics on words; Badly approximable numbers; Diophantine approximation; Mathematics; Matematik; Dynamical systems;

    Sammanfattning : The thesis takes as starting point diophantine approximation with focus on the area of badly approximable numbers. For the special kind of rationals, the q-adic rationals, we consider two types of approimations models, a one-sided and a two-sided model, and the sets of badly approximable numbers they give rise to.
