  5. 4. Simulation and Evaluation of Urban Rail On-board Crowding

    Författare :Soumela Peftitsi; Erik Jenelius; Oded Cats; Andreas Tapani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

    Sammanfattning : As travel demand grows in many metropolitan areas, overcrowding in public transport systems has become a major issue. Crowding distribution can be highly uneven over station platforms and multi-car transit vehicles. This implies that cars are not equally utilized and thus, passengers perceive on-board crowding higher. LÄS MER

  7. 5. Long-term performance of polymeric materials in nuclear power plants

    Författare :Payam Pourmand; Ulf W. Gedde; Sue Burnay; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EPDM; thermal ageing; radiation ageing; portable NMR spectroscopy; modulus profiling; condition monitoring; plasticizer migration; Kemi; Chemistry;

    Sammanfattning : Access to energy is crucial for modern societies to function sustainably. In addition, nuclear power has for a long time been considered a reliable source of energy. However, the majority of nuclear power plants are reaching the end of their service lifetimes, and it is crucial to verify that every component can withstand the added service time. LÄS MER
