    Abstract : The design of a mechatronic agent capable of navigating autonomously in a changing and perhaps previously unfamiliar environment is a very challenging issue. This thesis addresses this issue from both functional and system perspectives. READ MORE

  6. 4. Theory and Applications of Tri-Axial Electromagnetic Field Measurements

    Author : Roger Karlsson; Bo Thid'e; Tobia Carozzi; Gudmund Wannberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; polarisation; polarization; Stokes parameters; antenna; radio waves; whistler wave; SEE; direction-finding; statistics; Poynting theorem; Rymd- och plasmafysik; Space physics; Rymdfysik;

    Abstract : Polarisation, which was first studied in optics, is a fundamental property of all electromagnetic fields. A convenient way to describe the polarisation of two dimensional electromagnetic fields is given by the Stokes parameters. This thesis deals with different aspects of wave polarisation and electromagnetic field measurements. READ MORE

  7. 5. Synergistic Strategies in Multi-Robot Systems: Exploring Task Assignment and Multi-Agent Pathfinding

    Author : Yifan Bai; George Nikolakopoulos; Tomi Westerlund; Luleå tekniska universitet; []
