  1. 21. Mechanical Load Identification for Spontaneous Tool Failure Monitoring

    Författare :Jinming Zhou; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Monitoring; Cutting force; Identification; Cutting; Manufacturing; materialteknik;

    Sammanfattning : The problem of spontaneous cutting tool failure, such as tool chipping and breakage, is becoming more and more important in the manufacturing technology. The sponataneous tool failure is usually associated with the stresses subjected on the tool during a metal cutting process. LÄS MER

  3. 22. Modeling of fracture and damage in rubber under dynamic and quasi-static conditions

    Författare :Elsiddig Elmukashfi; Martin Kroon; Krishnaswami Ravi-Chandar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Elastomers are important engineering materials that have contributed to the different technical developments and applications since the 19th century. The study of crack growth mechanics for elastomers is of great importance to produce reliable products and therefore costly failures can be prevented. LÄS MER

  4. 23. Efficiency of the trackwork scheduling process in Sweden

    Författare :Daria Ivina; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railways; Maintenance management; Trackwork scheduling; Project Uncertainties; Lean; Efficiency;

    Sammanfattning : Efficient scheduling is vital for railway maintenance, which is increasingly challenged by rising train traffic and infrastructure wear. Trackwork often necessitates the reduction of train speeds and the partial or complete closure of tracks. LÄS MER

  5. 24. Adaptive Supervision Online Learning for Vision Based Autonomous Systems

    Författare :Kristoffer Öfjäll; Michael Felsberg; Kostas Daniilidis; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Driver assistance systems in modern cars now show clear steps towards autonomous driving and improvements are presented in a steady pace. The total number of sensors has also decreased from the vehicles of the initial DARPA challenge, more resembling a pile of sensors with a car underneath. LÄS MER
