  1. 1. IC-engine intake noise predictions based on linear acoustics

    Författare :Magnus Knutsson; Mats Åbom; Antonio Torregrosa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Sammanfattning : Shorter product development cycles, densely packed engine compartments and intensified noise legislation increase the need for accurate predictions of IC-engine air intake noise at early stages. The urgent focus on the increasing CO2 emissions and the efficiency of IC-engines, as well as new techniques such as homogeneous charge compression ignition (HCCI) might worsen the noise situation.

  4. 3. Thermal stability and mechanical properties of TiAlN-based multilayer and monolithic coatings

    Författare :Axel Knutsson; Magnus Odén; Lennart Karlsson; Grégory Abadias; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis explores the thermal stability, microstructure, mechanical properties and cutting performance of multilayer and monolithic cubic TiAlN hard coatings. The aim is to increase the understanding of how the coatings’ microstructure and properties are affected by a layered structure when exposed to high temperatures. LÄS MER

  5. 4. Learning Multidimensional Signal Processing

    Författare :Magnus Borga; Hans Knutsson; Josef Kittler; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The subject of this dissertation is to show how learning can be used for multidimensional signal processing, in particular computer vision. Learning is a wide concept, but it can generally be defined as a system’s change of behaviour in order to improve its performance in some sense. LÄS MER

  7. 5. Single and Multiple Motion Field Estimation

    Författare :Magnus Hemmendorff; Hans Knutsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents a framework for estimation of motion fields both for single and multiple layers. All the methods have in common that they generate or use constraints on the local motion. Motion constraints are represented by vectors whose directions describe one component of the local motion and whose magnitude indicate confidence. LÄS MER
