  1. 11. Robust self-localization of mobile robots in dynamic environments using scan matching algorithms

    Författare :Ola Bengtsson; Christian Schlegel; Chalmers tekniska högskola Göteborg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobile robot; Self-localization; Scan matching algorithm; Changed environments; Dynamic environments; o-variance matrix; Kalman filter; Signal processing; Signalbehandling;

    Sammanfattning : The most fundamental task for any mobile robot is to perform self-localization in the world in which it is currently active, i.e. determine its position relative its world. Encoders that count wheel rotations are often used, which can be turned into relative position estimates by mean of integration. LÄS MER

  3. 12. Mobile robot navigation and map generation using range measurements

    Författare :Johan Forsberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : This thesis is on mobile robot navigation using range sensors. The two sensors types used are time-of-flight lasers and sheet-of-light range cameras, both giving densely spaced range measurements. Map generation and navi gation are achieved in indoor environments, even when there are lots of disturbing objects giving cluttered range measurements. LÄS MER

  4. 13. Digital model-driven retail supply chain management

    Författare :Emmelie Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D scanning; Matching technology; Digital product fitting; Retail supply chains; Digital customer models; Mass customization; Design science; Product variety; Digitalization; Digital product models;

    Sammanfattning : The purpose of this thesis is to increase the understanding of how matching of digital models of products and customers can be used to shift the performance frontier in retail supply chains. This thesis puts forward the matching of digital models as an operational practice used by retail supply chains. LÄS MER

  5. 14. Bayesian Inference in Terrain Navigation

    Författare :Niclas Bergman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Terrain navigation is a concept for autonomous aircraft navigation. If measurements of the terrain height over mean sea-level are collected along the aircraft flight path, an estimate of the aircraft position can be formed by matching these measurements with a digital reference terrain map. This matching is a recursive nonlinear estimation problem. LÄS MER

  7. 15. Optimization, Matroids and Error-Correcting Codes

    Författare :Martin Hessler; Johan Wästlund; Olof Heden; Faina I. Solov´eva; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : The first subject we investigate in this thesis deals with optimization problems on graphs. The edges are given costs defined by the values of independent exponential random variables. We show how to calculate some or all moments of the distributions of the costs of some optimization problems on graphs. LÄS MER
