  1. 1. Group Representations and a Study of M-groups

    Kandidat-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Max Nilsson; [2020]
    Nyckelord :group theory; character theory; representation theory; M-groups; Mathematics and Statistics;

    Sammanfattning : In this thesis we introduce some basic concepts in representation theory such as Schur’s Lemma, induced representations and M-groups. These concepts are then used in particular on a group G_96 of order 96, in order to determine its irreducible representations and its character table. LÄS MER

  2. 2. The upper and lower bounds on Korenblum’s constant

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Åke Wettergren; [2020]
    Nyckelord :Complex Analysis; Bergman Space; Korenblum s constant; Optimization; Mathematics and Statistics;

    Sammanfattning : The purpose of this thesis is to study complex analysis, the Bergman space and Korenblum's conjecture. This is done in three parts. In the first part the proofs that the conjecture is true are studied, giving lower bounds of Korenblum's constant. The first proof is explained in detail, to make it as accessible as possible to more people. LÄS MER

  3. 3. Detecting Deepfakes and Forged Videos Using Deep Learning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Emil Johansson; [2020]
    Nyckelord :Image Analysis; Deepfake; Deep Learning; Neural Networks; FaceSwap; Face2Face; Neural Textures; Mathematics and Statistics;

    Sammanfattning : Over just a few years, methods to manipulate videos have become so sophistica- ted that even someone without much expertise or computational resources can forge videos inseparable from pristine ones to the human eye. These methods can for instance insert a person in a video or manipulate their lip movements to make them say anything of the manipulator’s liking. LÄS MER

  4. 4. The Hanging Rope: A Convex Optimization Problem in the Calculus of Variations

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Erik Steen; [2020]
    Nyckelord :Elasticity theory; non-linear materials; calculus of variation; convex analysis; Legendre transform; Mathematics and Statistics;

    Sammanfattning : We study the problem first introduced by Verma and Keller in 1984 of how to taper a heavy rope such that its elongation is minimized. The problem is stated as an optimization problem of a functional J[w]. Specifically we provide a proof of optimality for the solution using traditional convex optimization techniques. LÄS MER

  5. 5. Blood Cell Data Augmentation using Deep Learning Methods

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Oskar Klang; Martin Carlberg; [2020]
    Nyckelord :Image analysis; deep learning; data augmentation; generative adversarial networks; GAN; Mathematics and Statistics;

    Sammanfattning : In this thesis we aim to improve classification performance on blood cell imagesby using deep learning techniques to augment data. The thesis was conductedat CellaVision, a company providing digital solutions for medical microscopy inthe field of hematology. LÄS MER
