Human error has been implicated as a causal factor in a large proportion of road accidents. Automated driving systems purport to mitigate this risk, but self-driving systems that allow a driver to entirely disengage from the driving task also require the

Strategies to Limit Cognitive Impairments under Sleep Restriction: Relationship to Stress Biomarkers
Adding relaxation techniques during nap or auditory stimulation of EEG slow oscillation (SO) during nighttime sleep may limit cognitive impairments in sleep-deprived subjects, potentially through alleviating stress-releasing effects.

Effect of cylindrical longitudinal grinding process on surface integrity of 18CrNiMo7–6 steel
In order to explore the influence of the grinding process parameters on the surface roughness and surface layer residual stress of 18CrNiMo7–6 steel, the cylindrical longitudinal grinding experiment was carried out by using an end cylindrical grinder ...

Finite-element method for the analysis of surface stress concentration factor and relative stress gradient for machined surfaces [PDF]
Surface topography is an important parameter for evaluating the quality of surface machining, and the stress concentrations produced at notches can have a profound effect on the fatigue life of notched components. The stress concentration factor (SCF, Kt)
