  1. 11. System Identification with Multi-Step Least-Squares Methods

    Författare :Miguel Galrinho; Håkan Hjalmarsson; Manfred Deistler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The purpose of system identification is to build mathematical models for dynam-ical systems from experimental data. With the current increase in complexity of engineering systems, an important challenge is to develop accurate and computa-tionally simple algorithms, which can be applied in a large variety of settings.

  3. 12. Least squares modification of Stokes formula with application to the Estonian geoid

    Författare :Artu Ellmann; KTH; []
    Nyckelord :geoid; stokes formula; least sequares modification; total topographic correction; total atmospheric correction; gps levelling;

    Sammanfattning : Many applications in geodesy,geophysics and engineering require physically defined heightsrelated to an equipotential surface of the Earth, thegeoid.During the last two decades theincreased need for refined geoid models has been driven by thedemands of users of GPS, who nowadays must transformGPS-derived geodetic heights into orthometric heights, makingthem compatible with the local vertical datum.
