  1. 21. Selected Applications of Switched Capacitor Circuits : RF N-Path Filters and ΣΔ Modulators

    Författare :Fahad Qazi; Jerzy Dabrowski; Atila Alvandpour; Henrik Sjöland; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electronic circuits based on switches and capacitors have been used in various applications for several decades. The common switched capacitor (SC) circuits have made their career primarily in analog filters and data converters due to high immunity to capacitance mismatch in integrated circuit (IC) technologies.

  3. 22. On Control and Estimation of Large and Uncertain Systems

    Författare :Olle Kjellqvist; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis contains an introduction and six papers about the control and estimation of large and uncertain systems. The first paper poses and solves a deterministic version of the multiple-model estimation problem for finite sets of linear systems. The estimate is an interpolation of Kalman filter estimates.

  4. 23. Predictive Control for Wireless Networked Systems in Process Industry

    Författare :Erik Henriksson; Karl H. Johansson; Henrik Sandberg; Tore Hägglund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model predictive control; networked control systems; wireless systems; process industry; automatic control;

    Sammanfattning : Wireless networks in industrial process control enable new system architectures and designs. However, wireless control systems can be severely affected by the imperfections of the communication links. LÄS MER

  5. 24. GNSS-aided INS for land vehicle positioning and navigation

    Författare :Isaac Skog; Peter Händel; Bengt Boberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : This thesis begins with a survey of current state-of-the art in-car navigation systems. The pros and cons of the four commonly used information sources — GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map information — are described. Common filters to combine the information from the various sources are discussed. LÄS MER

  7. 25. Development of new NMR techniques and structural characterization of complexes between the N-terminal domain of the E. coli arginine repressor and operator DNA

    Författare :Patrik Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis includes the development of new solution NMR methods for the study of biomolecules and the characterization of complexes between the N-terminal domain of the E. coli arginine repressor (ArgR-N) and operator DNA. LÄS MER
