  1. 26. Model calibration methods for mechanical systems with local nonlinearities

    Författare :Yousheng Chen; Andreas Linderholt; Thomas Abrahamsson; Gaëtan Kerschen; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model calibration; finite element modelling; nonlinear structural dynamics; pre-test planning; multi-sinusoidal excitation; vibrational testing; cross validation; Maskinteknik; Mechanical Engineering;

    Sammanfattning : Most modern product development utilizes computational models. With increasing demands on reducing the product development lead-time, it becomes more important to improve the accuracy and efficiency of simulations. LÄS MER

  3. 27. Self-calibration and direct georeferencing in terrestrial laser scanning

    Författare :Yuriy Reshetyuk; Lars E. Sjöberg; Milan Horemuz; Hansjörg Kutterer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terrestrial laser scanning; self-calibration; direct georeferencing; error sources; Surveying; Lantmäteri;

    Sammanfattning : An important step in data processing from terrestrial laser scanning (TLS) is georeferencing, i.e. transformation of the scanner data (point clouds) into a real world coordinate system, which is important for their integration with other geospatial data. LÄS MER

  4. 28. Calibration of Probabilistic Predictive Models

    Författare :David Widmann; Fredrik Lindsten; Meelis Kull; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; Matematisk statistik;

    Sammanfattning : Predicting unknown and unobserved events is a common task in many domains. Mathematically, the uncertainties arising in such prediction tasks can be described by probabilistic predictive models. Ideally, the model estimates of these uncertainties allow us to distinguish between uncertain and trustworthy predictions. LÄS MER

  5. 29. Calibration of Urban Network Capacities

    Författare :Guang Wei; Gunnar Flötteröd; Joakim Ekström; Zhenliang Ma; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Capacity of a road in an urban network is defined as the maximum number of vehicles which could pass this road in a unit time. Since travel delays occur when the travel demand exceeds the capacity, performance of congestion estimation strongly depends on capacity values. LÄS MER

  7. 30. Weighted Regression with Application to Array Antennas

    Författare :Astrid Lundgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; array antenna; weighted regression; statistical estimation theory; modelling; calibration;

    Sammanfattning : A nonlinear system can be modelled with a simple linear model ifthe model is only valid locally. This can be done by assigningweights to the estimation data, as a function of the distance tothe modelled point. The weighting is here used to develop adirection-dependent calibration method for array antennas. LÄS MER
