  1. 16. Fatigue and Corrosion Fatigue Fracture of a Plasma Nitrided, Laser Hardened, and Galvanized B-Mn Steel

    Författare :Pedro De la Cruz Rodrígues; Birger Karlsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Fundamental and technological aspects of fatigue and fracture of conventional and advanced material are topics of primary importance to the development of materials science and engineering. Surface treatments have been established to improve the surface properties of material against surface phenomenon such as wear, corrosion, fatigue and corrosion fatigue. LÄS MER

  3. 17. Cutting Edge Titanium-based CVD Hard Coatings

    Författare :Linus von Fieandt; Mats Boman; Ulf Jansson; Erik Lindahl; Tommy Larsson; Henrik Pedersen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CVD; Hard coatings; Ti C; N ; TiN;

    Sammanfattning : Modern tools for metal cutting applications, such as turning or milling, are typically improved with a thin protective coating. Despite being only a few microns thick, the coating can increase the lifetime of the tool by more than 100 times compared to an uncoated tool. Two different types of techniques are normally used to deposit the coatings, i. LÄS MER

  4. 18. Inertial Navigation and Mapping for Autonomous Vehicles

    Författare :Martin Skoglund; Fredrik Gustafsson; Thomas Schön; Tim Bailey; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SLAM; Inertial Navigation; Filtering; Smoothing; Cameras; Optimisation; Autonomous;

    Sammanfattning : Navigation and mapping in unknown environments is an important building block for increased autonomy of unmanned vehicles, since external positioning systems can be susceptible to interference or simply being inaccessible. Navigation and mapping require signal processing of vehicle sensor data to estimate motion relative to the surrounding environment and to simultaneously estimate various properties of the surrounding environment.

  5. 19. The Location and Variability of Southern ocean Fronts

    Författare :Robert M. Graham; Agatha M. de Boer; Jonas Nycander; Qiong Zhang; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The location of fronts has a direct influence on both the physical and biological processes in the Southern Ocean. Moreover, the Subtropical Front (STF) is believed play a key role in the global climate system. LÄS MER
