  2. 11. Nonlinear Approaches to Periodic Signal Modeling

    Author : Emad Abd-Elrady; Torsten Söderström; Torbjörn Wigren; Jonas Sjöberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cramer-Rao bounds; frequency estimation; identification; limit cycle; nonlinear systems; periodic signals; Wiener model structure; Signal processing; Signalbehandling; Signalbehandling; Signal Processing;

    Abstract : Periodic signal modeling plays an important role in different fields. The unifying theme of this thesis is using nonlinear techniques to model periodic signals. The suggested techniques utilize the user pre-knowledge about the signal waveform. This gives these techniques an advantage as compared to others that do not consider such priors. READ MORE

  4. 12. Adsorption Isotherm Parameter Estimation in Nonlinear Liquid Chromatography

    Author : Patrik Forssén; Bertil Gustafsson; Torgny Fornstedt; Georges Guiochon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High performance liquid chromatography HPLC ; Preparative chromatography; Competitive adsorption isotherm parameters; Perturbation peak PP method; Inverse method IM ; Computer simulation; Parameter estimation; Numerical method; Scientific Computing; Beräkningsvetenskap;

    Abstract : This thesis concerns the development and validation of methods for the industrially important area of adsorption isotherm parameter estimation in preparative, nonlinear high performance liquid chromatography (HPLC). Preparative chromatography is a powerful separation method to get pure compounds from more or less complex liquid mixtures, e.g. READ MORE

    Abstract : Filtering and reconstruction of signals play a fundamental role in modern signal processing, telecommunications, and control theory and are used in numerous applications. The feedback principle is an important concept in control theory. READ MORE

  7. 15. Estimation and Detection with Applications to Navigation

    Author : David Törnqvist; Fredrik Gustafsson; Hugh Durrant-Whyte; Linköpings universitet; []
    Keywords : Navigation; SLAM; Particle Filter; Estimation; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The ability to navigate in an unknown environment is an enabler for truly utonomous systems. Such a system must be aware of its relative position to the surroundings using sensor measurements. It is instrumental that these measurements are monitored for disturbances and faults. READ MORE
