  3. 3. Model Reduction and Parameter Estimation for Diffusion Systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Bharath Bhikkaji; Uppsala universitet.; Uppsala universitet.; [2004]
    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; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik 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

  4. 4. Subspace-Based Parameter Estimation Problems in Signal Processing

    University dissertation from Department of Information Technology, Uppsala University
