    Abstract : This thesis deals with estimation and classification problems of non-stationary processes in a few special cases.In paper A and paper D we make strong assumptions about the observed signal, where a specific model is assumed and the parameters of the model are estimated. READ MORE

  7. 5. Model Reduction and Parameter Estimation for Diffusion Systems

    Author : Bharath Bhikkaji; Torsten Söderström; Claes Breitholtz; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion system; Partial differential equations PDEs ; Model reduction; PDE solvers; Finite difference approximation; Chebyshev polynomials; System identification; Parameter estimation; Recursive estimation; Frequency domain estimation; Signal processing; Signalbehandling;

    Abstract : Diffusion is a phenomenon in which particles move from regions of higher density to regions of lower density. Many physical systems, in fields as diverse as plant biology and finance, are known to involve diffusion phenomena. Typically, diffusion systems are modeled by partial differential equations (PDEs), which include certain parameters. READ MORE
