  1. 1. Maximally Supersymmetric Models in Four and Six Dimensions

    Författare :Fredrik Ohlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Taub-NUT space; Flat connections; Topologically non-trivial connections; 0 theory; Maximal supersymmetry; 2; Circle fibrations; Yang-Mills theory;

    Sammanfattning : We consider two examples of maximally supersymmetric models; the N=4 Yang-Mills theory in four dimensions and the (2,0) theory in six dimensions. The first part of the thesis serves as an introduction to the topics covered in the appended research papers, and begins with a self-contained discussion of principal fibre bundles and symplectic geometry.

  3. 2. Perturbative Aspects of Supersymmetric Yang-Mills Theory on T3

    Författare :Fredrik Ohlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is concerned with perturbative aspects of supersymmetric Yang-Mills theory in a space-time of the form T3xR, in the regime where the gauge coupling is weak. Wave functions of vacuum states of super Yang-Mills theoriesare supported on the moduli space of flat connections, and we consider a semi-classical treatment of such theories, obtained by expanding the fields around some normalizable zero energy background field configuration.

  5. 4. Data-driven personalized healthcare : Towards personalized interventions via reinforcement learning for Mobile Health

    Författare :Alexander Galozy; Sławomir Nowaczyk; Mattias Ohlsson; Fredrik Johansson; Högskolan i Halmstad; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information Driven Care; Electronic Health Records; Machine Learning; Reinforcement Learning;

    Sammanfattning : Medical and technological advancement in the last century has led to the unprecedented increase of the populace's quality of life and lifespan. As a result, an ever-increasing number of people live with chronic health conditions that require long-term treatment, resulting in increased healthcare costs and managerial burden to the healthcare provider.
