  1. 6. Adaptive image compression with wavelet packets and empirical mode decomposition

    Författare :Anna Linderhed; Roland Wilson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis addresses the problem of using wavelet packets and empirical mode decomposition (EMD) for image compression. The wavelet packet basis selection algorithm is studied through an extensive experimental survey of the generated decomposition trees. LÄS MER

  4. 8. An Integration-Reduction Scheme for Simulation of Large Systems with Local Nonlinearity and Uncertainty - Application to moving load problems in railway mechanics

    Författare :Sadegh Rahrovani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte-Carlo simulations; time-integration; moving load problems; reliability analysis; exponential integrator; symplectic integrator; modal dominancy analysis;

    Sammanfattning : The focus of this research is mainly on computational efficiency, as future work is planned for reliability analysis that will be combined with design optimisation. Both these fields are known to be notoriously computationally demanding. LÄS MER

  5. 9. On Control and Deployment of Autonomous Service Robots

    Författare :Andreas Papadimitriou; George Nikolakopoulos; Christoforos Kanellakis; Martin Saska; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

    Sammanfattning : This thesis investigates the control, modeling, and localization of unmanned service robots to enable their autonomous operation in real-world applications. Recent developments in electronics and computational capability have enabled the inspection and maintenance via aerial and ground robotic platforms, thus creating novel research opportunities in the area of control frameworks of such robotics setups.
