  1. 11. Harmonic signal modeling based on the Wiener model structure

    Författare :Emad Abd-Elrady; Torsten Söderström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : The estimation of frequencies and corresponding harmonic overtones is a problem of great importance in many situations. Applications can, for example, be found in supervision of electrical power transmission lines, in seismology and in acoustics. LÄS MER

  3. 12. Fast Algorithms for Integral Equations and Least Squares Identification Problems

    Författare :Stefan Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast algorithms; Integral equations; Least squares; Identification;

    Sammanfattning : This work is concerned with fast algorithms for integral equations and least squares identification problems.The presentation is divided into three parts. In the first part a fast algorithm for solving systems oflinear equations with a matrix that is alm ost Toeplitz is derived and applied to Fredholm integral equations with stationary kernels.

  4. 13. Haptic Milling Simulation in Six Degrees-of-Freedom : With Application to Surgery in Stiff Tissue

    Författare :Magnus G. Eriksson; Jan Wikander; Dwight Meglan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surgical simulation; Virtual reality; Haptic feedback; Surgical training; Medical simulators; 3D visualization; Six degrees-of-freedom; Bone milling;

    Sammanfattning : The research presented in this thesis describes a substantial part of the design of a prototypical surgical training simulator. The results are intended to be applied in future simulators used to educate and train surgeons for bone milling operations. LÄS MER

  5. 14. Studies on identification of time-variant and time-varying nonlinear systems

    Författare :Anders Nordsjö; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis addresses same aspects of nonlinear systemidentification. In par ticular, it is assumed that theconsidered systems can be described by the Wiener model whichconsists of a dynamit linear part followed by a nonbnear partor the Haxnmerstein model in which the order of these twoblocks is reversed.

  7. 15. A study of vehicle fatigue damage predictions based on state estimations

    Författare :Ulrika Lagerblad; Artem Kulachenko; Henrik Wentzel; Costas Papadimitriou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; State estimations; Fatigue damage; Damage predictions; Fixed-lag Kalman Smoother; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Individual health monitoring of heavy vehicles is one of the keystones on which an optimized utility of a vehicle fleet is based. For many components mounted on the chassis of a heavy vehicle, failures due to fatigue is a major concern. LÄS MER
