  2. 21. Studies in Estimation of Patterned Covariance Matrices

    Author : Martin Ohlson; Timo Koski; Dietrich von Rosen; Augustyn Markiewicz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : Many testing, estimation and confidence interval procedures discussed in the multivariate statistical literature are based on the assumption that the observation vectors are independent and normally distributed. The main reason for this is that often sets of multivariate observations are, at least approximately, normally distributed. READ MORE

  4. 22. Regression methods in multidimensional prediction and estimation

    Author : Anders Björkström; Rolf Sundberg; Philip J Brown; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; regression; prediction; principal compnents regression; ridge regression; partial least squares; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Abstract : In regression with near collinear explanatory variables, the least squares predictor has large variance. Ordinary least squares regression (OLSR) often leads to unrealistic regression coefficients. Several regularized regression methods have been proposed as alternatives. READ MORE

  5. 23. Control and estimation of wall bounded flow systems

    Author : Jerome Hoepffner; KTH; []
    Keywords : ;

    Abstract : This thesis focuses on the application of linear feedback control and estimation to channel flow. Both the initial stage of the transition and the low Reynolds number turbulent cases are studied. From sensors at the wall, the state of the flow is estimated, using a stochastic description of the flow disturbances. READ MORE

  6. 24. Estimation of Nonlinear Greybox Models for Marine Applications

    Author : Fredrik Ljungberg; Martin Enqvist; Svante Gunnarsson; Håkan Hjalmarsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : As marine vessels are becoming increasingly autonomous, having accurate simulation models available is turning into an absolute necessity. This holds both for facilitation of development and for achieving satisfactory model-based control. READ MORE

  7. 25. Parameter and state estimation using audio and video signals

    Author : Magnus Evestedt; Alexander Medvedev; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : The complexity of industrial systems and the mathematical models to describe them increases. In many cases point sensors are no longer sufficient to provide controllers and monitoring instruments with the information necessary for operation. The need for other types of information, such as audio and video, has grown. READ MORE
