  1. 1. Structural Reformulations in System Identification

    Författare :Christian Lyzell; Martin Enqvist; Lennart Ljung; Alessandro Chiuso; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Dimension reduction; Subspace identification; Difference algebra;

    Sammanfattning : In system identification, the choice of model structure is important and it is sometimes desirable to use a flexible model structure that is able to approximate a wide range of systems. One such model structure is the Wiener class of systems, that is, systems where the input enters a linear time-invariant subsystem followed by a time-invariant nonlinearity. LÄS MER

  2. 2. On System Identification and Acoustic Echo Cancellation

    Författare :Per Åhgren; Peter Stoica; Peter Händel; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic echo cancellation; stereophonic acoustic echo cancellation; doubletalk detection; adaptive beamforming; adaptive filtering; system identification; recursive system identification; loudspeaker impulse response estimation; Signal processing; Signalbehandling;

    Sammanfattning : The topic of acoustic echo cancellation has received a lot of interest over the years. Even though the topic is relatively old, the increasing demand for hands-free telephony has made it more important than ever before. LÄS MER

  3. 3. Initialization Methods for System Identification

    Författare :Christian Lyzell; Lennart Ljung; Martin Enqvist; Magnus Jansson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Initialization methods; Regressor selection; Identifiability; Automatic control; Reglerteknik;

    Sammanfattning : In the system identification community a popular framework for the problem of estimating a parametrized model structure given a sequence of input and output pairs is given by the prediction-error method. This method tries to find the parameters which maximize the prediction capability of the corresponding model via the minimization of some chosen cost function that depends on the prediction error.

  5. 5. Entre identification et différenciation : La mère et l’amour dans la constitution de l’identité féminine dans La fille démantelée, La plage d’Ostende et Orlanda de Jacqueline Harpman

    Författare :Maria Snårelid; Maria Walecka-Garbalinska; Martine Renouprez; Stockholms universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; Harpman; psychoanalysis; preœdipal; primary narcissism; Kristeva; identification and differentiation; father of the individual prehistory; Freud; the subject’s eternal rebirth; narcissism and idealization; the symbolic; abjection; French; franska;

    Sammanfattning : The aim of this dissertation is to investigate the importance of the mother figure for the definition of the female identity in three novels by the Belgian writer and psychoanalyst Jacqueline Harpman: La fille démantelée, La plage d’Ostende and Orlanda. This perspective is largely motivated by the specific character of the mother-daughter relation which is crucial to the formation of female identity.
