Determination and classification of human stress index using nonparametric analysis of EEG signals / Norizam Sulaiman
Regardless of type of stress, either mental stress, emotional stress or physical stress, it definitely affects human lifestyle and work performance. There are two prominent methods in assessing stress which are psychological assessment (qualitative method) and physiological assessment (quantitative...
