Fatigue, alcohol and performance impairment [PDF]

Nature, 1997
Reduced opportunity for sleep and reduced sleep quality are frequently related to accidents involving shift-workers1,2,3. Poor-quality sleep and inadequate recovery leads to increased fatigue, decreased alertness and impaired performance in a variety of cognitive psychomotor tests4.

Investigating Fatigue Performance on the Foamed Asphalt Specimens Generated Using Different Foam Properties [PDF]

, 2012
An evaluation of fatigue resistance for foamed asphalt mixture is very demanding since the binder is not continuously distributed on the aggregate surface and this mixtures contains water, the content of which dramatically affects the mechanical ...

Muscle fatigue during assisted violin performance

Ergonomics, 2023
Muscle fatigue is a primary risk factor in developing musculoskeletal disorders, which affect up to 93% musicians, especially violinists. Devices providing dynamic assistive support (DAS) to the violin-holding arm can lessen fatigue. The objective was to assess DAS effects on electromyography median frequency and joint kinematics during a fatiguing ...

High-resolution 3D weld toe stress analysis and ACPD method for weld toe fatigue crack initiation [PDF]

, 2019
Weld toe fatigue crack initiation is highly dependent on the local weld toe stress-concentrating geometry including any inherent flaws. These flaws are responsible for premature fatigue crack initiation (FCI) and must be minimised to maximise the fatigue
