  5. 4. The criterion-related validity of pupil diamater as a measurement of mental fatigue in air traffic controllers

    Master-uppsats, KTH/Ergonomi

    Författare :Sandra Jonasson; [2021]
    Nyckelord :;

    Sammanfattning : Air traffic controllers face serious responsibilities and demanding work tasks on duty, which can lead to them experiencing mental fatigue. Due to the adverse effects that fatigue has on air traffic controllers’ performance, it is important to be able to measure their fatigue levels while on duty in order to be able to intervene when the fatigue reaches critical levels.

  7. 5. Life and fracture in very high cycle fatigue of a high strength steel

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Daniel Karlsson; [2021]
    Nyckelord :Very high cycle fatigue; VHCF; Fractography; Fine granular area; FGA; High strength tool steel; Ultrasonic testing equipment;

    Sammanfattning : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. LÄS MER
