  1. 1. 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

    Sammanfattning : This thesis consists of the four papers listed below and a survey of the research area. I Lina J. Andrén: Avoiding (m, m, m)-arrays of order n = 2k II Lina J. Andrén: Avoidability of random arrays III Lina J. LÄS MER

  4. 3. Random tournaments and random circuits

    Författare :Pontus Andersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Poisson-Dirichlet distribution; random circuit decomposition; random tournament; subgraph count; MATEMATIK; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : This thesis is devoted to two different topics in the area of probabilistic combinatorics: asymptotic behaviour of subgraph counts in a random tournament and random circuit decompositions of complete graphs.Let Tn be a random tournament on n vertices, chosen uniformly from all 2(n2) such tournaments, and let D be an arbitrary directed graph.

  5. 4. Geometry of numbers, class group statistics and free path lengths

    Författare :Samuel Holmin; Pär Kurlberg; Yiannis Petridis; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geometry of numbers; lattices; class numbers; class groups; free path lengths; Mathematics; Matematik;

    Sammanfattning : This thesis contains four papers, where the first two are in the area of geometry of numbers, the third is about class group statistics and the fourth is about free path lengths. A general theme throughout the thesis is lattice points and convex bodies. LÄS MER

  7. 5. 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
