  1. 16. The language learning infant: Effects of speech input, vocal output, and feedback

    Författare :Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; human; language; language acquisition; perception; production; humanoid; development; model; embodied system; speech signal processing; vocal tract morphology; acoustic; speech input; information processing; scaling; interaction; growth; infant; imitation; feedback; perceptual salience; modeling; Phonetics; Fonetik; Phonetics; fonetik;

    Sammanfattning : This thesis studies the characteristics of the acoustic signal in speech, especially in speech directed to infants and in infant vocal development, to gain insight on essential aspects of speech processing, speech production and communicative interaction in early language acquisition. Three sets of experimental studies are presented in this thesis. LÄS MER

  3. 17. Identification of dynamic errors-in-variables models

    Författare :Kaushik Mahata; Torsten Söderström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

    Sammanfattning : The problem of identifying dynamic errors-in-variables models is of fundamental interest in many areas like process control, array signal processing, astronomical data reduction. In recent years, this field has received increased attention of the research community. LÄS MER

  4. 18. Interference Mitigation and Synchronization for Satellite Communications

    Författare :Joel Grotz; Björn Ottersten; Dirk Slock; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning :  Within this thesis, the satellite broadcast scenario of geostationary satellites is reviewed. The densely crowded geostationary arc in the common broadcast frequencies may create significant interference from adjacent satellites (ASI). LÄS MER

  5. 19. Studies on Design and Implementation of Low-Complexity Digital Filters

    Författare :Henrik Ohlsson; Lars Wanhammar; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-complexity digital filters; lattice wave digital filters LWDFs ; digital down converter DDC ; analog-to-digital converters ADCs ; Signal processing; Signalbehandling;

    Sammanfattning : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in most digital signal processing (DSP) systems and are, for example, used for interpolation and decimation. LÄS MER

  7. 20. Parameter estimation and model based control design of drive train systems

    Författare :Mats Tallfors; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; control; drive train; estimation; identification; mechanical; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : The main control task in many speed-controlled drives is to eliminate or reduce the load speed error caused by the load torque disturbance and reduce oscillations as quickly as possible. This thesis addresses different aspects of identification and control of such resonant elastic systems. LÄS MER
