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

    Författare :Henrik Andreasson; Achim Lilienthal; Jim Little; Örebro universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Järnhanteringens dynamik : Produktion, lokalisering och agglomerationer i Bergslagen

    Författare :Fredrik Olsson; Olle Krantz; Dan Bäcklund; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; iron industry; agglomerations; clusters; regions; parishes; localisation; early modern; regional industrialisation; employment structure; iron production; bar iron export; Sweden; Bergslagen; Central Sweden; Economic history; Ekonomisk historia;

    Sammanfattning : Abstract This thesis explores early modern industrial dynamics and especially the long-term performance of iron production and its localisation in Central Sweden during the period 1368-1910. Iron production, iron export and localisation in a national perspective as well as the regional industrial development in Central Sweden during the period 1805-1910 are studied. LÄS MER
