  2. 21. Human-Robot Interaction and Mapping with a Service Robot : Human Augmented Mapping

    Author : Elin Anna Topp; Henrik I. Christensen; Benjamin J. Kuipers; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Robotics; Human-Robot Interaction; Cognitive modelling; Representation of space; Computer science; Datavetenskap;

    Abstract : An issue widely discussed in robotics research is the ageing society with its consequences for care-giving institutions and opportunities for developments in the area of service robots and robot companions. The general idea of using robotic systems in a personal or private context to support an independent way of living not only for the elderly but also for the physically impaired is pursued in different ways, ranging from socially oriented robotic pets to mobile assistants.

  4. 22. Aspects of vacuum moduli in string theory

    Author : Matthew Magill; Magdalena Larfors; James Sparks; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; string compactifications; g structures; homological algebra; Theoretical Physics; Teoretisk fysik;

    Abstract : In this thesis we explore geometric aspects of the space of vacua in supersymmetric string compactifications. More specifically, we will look at heterotic strings compactified on Calabi-Yau manifolds and, separately, G2 structure manifolds. READ MORE

  5. 23. Heterotic Compactifications in the Era of Data Science

    Author : Robin Schneider; Magdalena Larfors; Yang-Hui He; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Calabi-Yau; string compactifications; machine learning; Theoretical Physics; Teoretisk fysik;

    Abstract : The goal of this thesis is to review and investigate recent applications of machine learning to problems in string theory. String theory, the leading candidate for a unification of gravity and the standard model of particle physics, requires the introduction of additional space-time dimensions. READ MORE

  6. 24. Selected Topics in Continuum Percolation : Phase Transitions, Cover Times and Random Fractals

    Author : Filipe Mussini; Erik I. Broman; Hermine Biermé; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poisson point process; Percolation; Boolean model; Quasi-isometries; Cover times; Poisson cylinder process; Ellipsoid process; Phase transition; Random fractals; Mathematics; Matematik;

    Abstract : This thesis consists of an introduction and three research papers. The subject is probability theory and in particular concerns the topics of percolation, cover times and random fractals.Paper I deals with the Poisson Boolean model in locally compact Polish metric spaces. READ MORE

  7. 25. Studies in general relativity and quantum mechanics

    Author : Nuno Baltazar Fogaça Barros e Sá; Marc Henneaux; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : This work approaches two different subjects in theoretical Physics: General relativity, and the geometry of the space of quantum states.Concerning the former subject we review the Lagrangian and Hamiltonian formulations of General relatvity with particular emphasis on its description by means of tetrads and connections, either real or complex self-dual.
