  1. 21. Reliability analysis and cost modeling of degrading systems

    Författare :Saurabh Kumar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Degradation is an on-going process in systems, equipments and components subjected to various stresses and adverse operating conditions. The factors influencing the degradation process may adversely affect the system or component performance. LÄS MER

  3. 22. Österreichs Opposition im Rat der Europäischen Union und ihre Auswirkungen auf die Richtlinienumsetzung

  5. 24. Evaluation and Modelling of Short Haul Intermodal Transport Systems

    Författare :Behzad Kordnejad; Sebastian Stichel; Bo-Lennart Nelldal; Sebastiaan Meijer; Johan Woxenius; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportvetenskap; Transport Science;

    Sammanfattning : Conventional intermodal rail freight transport systems have proved themselves competitive and able to offer cost-leadership on long distances and in endpoint relations between two nodes. Several studies within intermodal transports have made contributions in finding the minimum distance, the “break-even” distance that an intermodal door-to-door shipment can compete with unimodal road.
