  1. 31. Long-term Performance of PVC and CSPE Cables used in Nuclear Power Plants : the Effect of Degradation and Plasticizer migration

    Författare :Maria Ekelund; Ulf Gedde; Thomas Hjertberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCV; CSPE; cables; ageing; mechanical properties; plasticizer migratio; LIRA; life time prediction; Chemistry; Kemi;

    Sammanfattning : Enormous amounts of low voltage cables installed in a Swedish nuclear power plant are reaching their expected lifetimes. Since the cables are crucial to operational safety, it is of great importance that the actual condition of the installed cables is determined. LÄS MER

  4. 33. On Safety Validation of Automated Driving Systems using Extreme Value Theory

    Författare :Daniel Åsljung; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Verification; Autonomous Vehicles; Performance Evaluation; Automotive;

    Sammanfattning : Autonomous vehicles are expected to bring safer and more convenient transports in the future. When the system in the vehicle takes care of the driving, the driver is free to spend time on other things. LÄS MER

  5. 34. Occupational injuries and technological development : studies in the Swedish mining industry

    Författare :Vera Lucia Guimaraes Blank; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :occupational injuries; technological development; mining industry; injury risks; ;

    Sammanfattning : The relationship between technological development and occupational injuries is an issue that has received considerable attention in recent accident research. The evidence accumulated so far from studies comparing different technological alternatives as they evolve over time suggests that technological changes have not had a universal preventive effect with regard to injury-event occurrence.

  7. 35. Radiocesium in the forest and forest industry, Studies on the flow, occurrence and technological enhancement of radionuclides in the forest industry with emphasis on radiocesium

    Författare :Aaro Ravila; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; forestry technology; forestry; recovery; Recycling; enhancement; fallout; radiocesium; wood; ash; biofuel; Silviculture; radiation.; Skogsvetenskap; skogsbruk; skogsteknik;

    Sammanfattning : In the aftermath of the nuclear weapons testing and as compared with agriculture, the forest industry has received relatively little attention in spite of its large-scale use of radiocesium- contaminated wood and water. After the Chernobyl nuclear power plant accident in 1986, numerous studies of the forest environment have been conducted with respect to radionuclide transfer through the forest ecosystem or its many components.
