  2. 11. On methods for assistive mobile robots

    Author : Sven Rönnbäck; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : This thesis makes a contribution to the field of autonomous vehicles, especially for use on assistive wheelchairs. Methods and technologies for topological signature maps, obstacle avoidance, door passing, localization, and navigation are presented. READ MORE

  4. 12. Nanoscale electron tomography and compositional analysis of Aerotaxy nanowires

    Author : Axel Persson; -lup-obsolete; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transmission Electron Microscopy; Electron tomography; Nanowires; Aerotaxy;

    Abstract : One common goal of sample analysis is to provide structural, compositional, or functional data in order to improve production parameters. One instrument specialized in such structural and compositional analysis with a high spatial resolution is the transmission electron microscope (TEM). READ MORE

  5. 13. Simultaneous localization and mapping with robots

    Author : John Folkesson; Henrik I. Christensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer science; Computer science; Datalogi;

    Abstract : A fundamental competence of any mobile robot system is the ability to remain localized while operating in an environment. For unknown/partially known environments there is a need to combine localization with automatic mapping to facilitate the localization process. READ MORE

  6. 14. Risk and Vulnerability Analysis of Large Scale Technical Infrastructures - Electrical Distribution Systems

    Author : Jonas Johansson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The thesis treats the subject of risk and vulnerability analysis of large-scale technical infrastructures. In particular the focus is on the development of methods for vulnerability analysis of electrical distribution systems. The methods and the concepts behind them should nevertheless also be seen as applicable to other technical infrastructures. READ MORE

  7. 15. Infinite dimensional holomorphy in the ring of formal power series : partial differential operators

    Author : Henrik Petersson; Andrei Khrennikov; Sean Dineen; Växjö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Infinite dimensional holomorphy; Formal power series; Fourier-Borel transform; Paley-Wiener theorem; Fischer decomposition; Fischer pair; Fock space; Cauchy-Problem; Kergin operator; PDE-preserving; Pseudo-differential operators.; MATHEMATICS; MATEMATIK;

    Abstract : We study holomorphy in the ring of formal power series in an infinite number of variables. Thus we restrict our study to (infinite dimensional) holomorphy on sequence spaces and we show that we obtain a rich theory without requiring any topological structure on the domain space. We make a comprehensive PDO-study for the spaces under consideration. READ MORE
