  2. 2. Accuracy of turbocharged SI-engine simulations

    Författare :Fredrik Westin; KTH; []
    Nyckelord :boosting; turbocharging; supercharging; modelling; simulation; turbine;

    Sammanfattning : This licentiate thesis deals mainly with modelling ofturbocharged SIengines. A model of a 4-cylinder engine was runin both steady state and transient conditions and the resultswere compared to measured data. Large differences betweenmeasurements and simulations were detected and the reasons forthis discrepancy were investigated. LÄS MER

  3. 3. Simulation of turbocharged SI-engines - with focus on the turbine

    Författare :Fredrik Westin; Hans-Erik Ångström; Gordon P Blair; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering design; turbocharging simulation 1D turbine accuracy SI-engine; Konstruktionsteknik; Construction engineering; Konstruktionsteknik;

    Sammanfattning : The aim is to share experience gained when simulating (and doing measurements on) the turbocharged SI-engine as well as describing the limits of current state of the technology. In addition an overview of current boosting systems is provided. LÄS MER

  4. 4. Feature extraction based on a tensor image description

    Författare :Carl-Fredrik Westin; Linköpings universitet; []
    Nyckelord :Image analysis; Representation; Tensor; Hough transform; Möbius strip; Corner detection; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Feature extraction from a tensor based local image representation introduced by Knutsson in [37] is discussed. The tensor representation keeps statements of structure, certainty of statement and energy separate. LÄS MER

  5. 5. A Tensor Framework for Multidimensional Signal Processing

    Författare :Carl-Fredrik Westin; Gösta Granlund; Linköpings universitet; []

    Sammanfattning : This thesis deals with ltering of multidimensional signals. A large part of the thesis is devoted to a novel filtering method termed "Normalized convolution". The method performs local expansion of a signal in a chosen lter basis which not necessarily has to be orthonormal. LÄS MER
