  1. 1. Piecewise Linear Control Systems

    Author : Mikael Johansson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piecewise quadratic functions; Linear matrix inequalities; Convex optimization; Optimal control; Performance analysis; Piecewise linear Lyapunov functions; Piecewise quadratic Lyapunov functions; Quadratic stability; Lyapunov stability; Piecewise linear systems; Nonlinear systems; Fuzzy systems; Hybrid systems.; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : This thesis treats analysis and design of piecewise linear control systems. Piecewise linear systems capture many of the most common nonlinearities in engineering systems, and they can also be used for approximation of other nonlinear systems. READ MORE

  2. 2. Analysis and Design of Hybrid Systems

    Author : Stefan Pettersson; Chalmers University of Technology; []
    Keywords : asymptotic stability; Lyapunov theory; exponential stability; piecewise quadratic Lyapunov functions; hybrid systems; stability; linear matrix inequalities; nonlinear systems; LMIs; control theory; fuzzy systems;

    Abstract : Many physical systems today are modeled by interacting continuous and discrete event systems. Such hybrid systems contain both continuous and discrete states that influence the dynamic behavior. READ MORE

  3. 3. Enabling Internet-Scale Publish/Subscribe In Overlay Networks

    Author : Fatemeh Rahimian; Seif Haridi; Šarunas Girdzijauskas; Márk Jelasity; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Publish Subscribe; Content Distribution; Peer-To-Peer Overlay Network; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : As the amount of data in todays Internet is growing larger, users are exposedto too much information, which becomes increasingly more difficult tocomprehend. Publish/subscribe systems leverage this problem by providingloosely-coupled communications between producers and consumers of data ina network. Data consumers, i.e. READ MORE

  4. 4. Contributions to 3D Image Analysis using Discrete Methods and Fuzzy Techniques : With Focus on Images from Cryo-Electron Tomography

    Author : Magnus Gedda; Ewert Bengtsson; Stina Svensson; Carolina Wählby; Punam Saha; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; digital image analysis; 3D; fuzzy; algorithms; grey-weighted distance; region growing; electron tomography; tracing; fluorescence microscopy; Datoriserad bildanalys; Computerized Image Analysis;

    Abstract : With the emergence of new imaging techniques, researchers are always eager to push the boundaries by examining objects either smaller or further away than what was previously possible. The development of image analysis techniques has greatly helped to introduce objectivity and coherence in measurements and decision making. READ MORE

  5. 5. Computer Vision for Traffic Surveillance Systems : Methods and Applications

    Author : Saleh Javadi; Mattias Dahl; Michael Cree; Blekinge Tekniska Högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; Systems Engineering;

    Abstract : Computer vision solutions play a significant role in intelligent transportation systems (ITS) by improving traffic flow, safety and management. In addition, they feature prominently in autonomous vehicles and their future development. The main advantages of vision-based systems are their flexibility, coverage and accessibility. READ MORE
