    Sammanfattning : This thesis considers the stability and transition of incompressible boundary layers. In particular, the Falkner–Skan–Cooke boundary layer subject to a cylindrical surface roughness, and the Blasius boundary layer with applied localized suction are investigated. LÄS MER

  7. 5. Models of Surface Roughness with Applications in Paper Industry

    Författare :Jan-Olof Johansson; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistik; actuarial mathematics; operations research; programming; Matematik; Statistics; Mathematics; estimation.; Surface roughness; parametric models; operationsanalys; programmering; aktuariematematik; Wood; pulp and paper technology; Pappers- och massateknik;

    Sammanfattning : This thesis comprises general parametric models for surface roughness. The models can be used in several technical and natural applications but are here only applied to the micro-structure of paper. In that application, earlier models are generalized and new models introduced. LÄS MER
