This study proposes a concept for self-deployable shell structures made of connected shape memory polymer (SMP) shells, which are configured to a convex shape. In this research, the convex SMP shell is deformed from a flat configuration to convex one

In order to find out the topographic structure in alpha wave activity, the principal component analysis method was applied to 17 channel scalp EEGs. Three kind of topographic structures were obtained from the factor loadings of principal components a

Determination of the EEG sleep stages by clinicians is a time consuming task, because of a great amount of record obtained during one night. Therefore, an effective computer technique for an automatic processing EEG is strongly desired. We tried to m

In order to study the psychophysiological function of ""slow wave sleep (SWS), we are trying to identify the control mechanism of SWS. It is well known that the amount of SWS found in a sleep episode depends upon the length of wakefulness prior to th

The cross-correlation function between diurnal changes in 1/f-like fluctuations of the R-R interval and those of the sleep-waking stage was calculated based on the data from six normal subjects in order to investigate the interactions among circadian

A new mathematical method was developed to analyze time series. Applications of this method to the delta component of all-night sleep electroencephalogram (EEG) revealed new variations with double-rapid eye movement (REM)-sleep interval. The proposed
