This paper proposes a new method for analyzing brain activity from Electroencephalogram (EEG) based on a concept of instantaneous equivalent bandwidths (IEBWs). The essence of the method using the IEBW is to track bandwidths changes of EEG signals. The instantaneous equivalent band- widths are defined using positive time-frequency distributions. However, it is well known that non-negative bilinear distributions that satisfy the marginals do not exist. To solve the problem, Copula-based time…

The EEG signals of the frontal area in the arousal maintenance state against sleepiness have wide bandwidth as in the EEG of the occipital area, which strengthens speculation, i.e., the EEG desynchronization occurs because of the neuron activities from the frontal lobe to hypothalamus in order to maintain arousal state againstSleepiness.

Electroencephalogram-Based Approaches for Driver Drowsiness Detection and Management: A Review
This paper reviews the algorithms of electroencephalogram (EEG)-based drivers’ drowsiness detection (DDD) and addressed seven questions that helped in developing an EEG-based DDD system that is superior to the existing ones.


Tracking of the instantaneous bandwidth in bio-signals: the Copula-based positive distribution and generalized equivalent bandwidth
The results suggest that tracking the IEBW could be a useful index for automatic diagnostic of heart disease and a natural extension of a equivalent bandwidth for stationary random signals.
Copula-based positive time-frequency distributions of the phonocardiogram
This paper uses averaged spectrogram as a template in copula-based technique in order to construct a positive time-frequency distribution of the phonocardiogram, which has much better resolution in time and frequency domain than the spectrogram does.

On Unification of Equivalent Bandwidths of a Random Process
It is shown that the six EBWs are sorted into four kinds of EBW, and that the class suggested by Zakai provides a unified representation of the four, and it can be redefined by using Renyi's -order entropy, which strengthens Zakai's suggestion.
