conclusions postural stress among female machinists can increase the level of si to fairly risky and dangerous. also, changes in rating hand/wrist qec scores with hand/wrist si score were proportional in the studied samples. the si can increase under the influence of noise above 85 db, although it is not statistically significant. results there was no significant difference between work experie...

The logical effort method has appeared very convenient for fast estimation and optimization of single paths. However it necessitates a calibration of all the gates of the library and appears to be sub-optimal for a complex implementation. This is due to the inability of this model in capturing I/O coupling and input ramp effects. In this paper, we introduce a physically based extension of the l...

Both physical and mental effort are thought to affect vigilance. Mental effort is known for its vigilance declining effects, but the effects of physical effort are less clear. This study investigated whether these two forms of effort affect the EEG and subjective alertness differently. Participants performed a physical task and were subsequently presented with a mental task, or vice versa. Ment...
