  2. 1. Local visual feature based localisation and mapping by mobile robots

    Author : Henrik Andreasson; Achim Lilienthal; Jim Little; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mobile robotics; registration; localisation; SLAM; mapping; omnidirectional vision; 3D vision; appearance based; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : This thesis addresses the problems of registration, localisation and simultaneous localisation and mapping (SLAM), relying particularly on local visual features extracted from camera images. These fundamental problems in mobile robot navigation are tightly coupled. READ MORE

  4. 2. LOST IN LOCALISATION searching for exact results in supersymmetric gauge theories

    Author : Louise Anderson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extended Supersymmetry; Matrix Models; Large N-techniques; Supersymmetric Gauge Theory; Localisation; Topological Field Theory;

    Abstract : This thesis deals with one of the very basics of theoretical physics: computing observable quantities. In the language commonly used to describe the subatomic world, gauge theories, this problem is far from trivial as the observables are expressed in terms of infinite-dimensional integrals. READ MORE

  5. 3. Towards Precise Localisation : Subsample Methods, Efficient Estimation and Merging of Maps

    Author : Gabrielle Flood; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; localisation; map merging; subsample; stochastic analysis; time-difference-of-arrival;

    Abstract : Over the last couple of years audio and radio sensors have become cheaper and more common in our everyday life. Such sensors can be used to form a network, from which one can obtain distance measures by correlating the different received signals. READ MORE

  6. 4. Acoustic Sound Source Localisation and Tracking : in Indoor Environments

    Author : Anders Johansson; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Room acoustics; Speaker localisation; Tracking; State-space filter; Sequential Monte Carlo method; Particle filter;

    Abstract : With advances in micro-electronic complexity and fabrication, sophisticated algorithms for source localisation and tracking can now be deployed in cost sensitive appliances for both consumer and commercial markets. As a result, such algorithms are becoming ubiquitous elements of contemporary communication, robotics and surveillance systems. READ MORE

  7. 5. 7D supersymmetric Yang-Mills theory on toric and hypertoric manifolds

    Author : Andreas Rocén; Tobias Ekholm; Andrew Swann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Yang-Mills theory; supersymmetry; toric geometry; hypertoric geometry; Sasaki-Einstein; 3-Sasaki; localisation; special functions; Mathematics; Matematik;

    Abstract : This thesis consists of an introduction and three research papers in the general area of geometry and physics. In particular we study 7D supersymmetric Yang-Mills theory and related topics in toric and hypertoric geometry. Yang-Mills theory is used to describe particle interactions in physics but it also plays an important role in mathematics. READ MORE
