Linear temporal characteristics of heart interbeat interval as an index of the pilot's perceived risk

Article Abstract:

Normally in human-machine systems, the humans operate and control the machines and the humans monitor any performance degradation and malfunctioning but in the concept of adaptive automation (AA), the control task between the operator and automated system is passed back and forth. An experiment was conducted where linear dynamical characteristics of 60 pilots heart interbeat intervals were used to assess their perceived risk of the consequences due to their inability to perform.

Influence of fatigue time and level on increases in postural sway

Article Abstract:

The influence of fatigue time and fatigue level on the increases in postural sway during quiet standing is investigated. Fatigue level effects have implied a dose-response relationship between localized muscle fatigue and risk of falling that can have important implications in work/rest cycle scheduling for occupations at risk of injurious falls.

Complete recovery time after exhaustion in high-intensity work

Article Abstract:

A study was conducted to investigate complete recovery time (CRT) after exhaustion in high-intensity work. The results of the study indicated that heart rate (HR) required the longest time to recovery and consequently HR data were adopted to set the CRT.
