Heart rate variability (HRV) is a noninvasive marker for the cardiovascular system and the
substantial influence of this system on the autonomous nervous system (ANS). Contact and …

Abstract Objective The Poincaré plot is a two-dimensional state-space approach, where a
timed signal is plotted against itself after a time delay, enabling determination of the dynamic …

Nonlinear dynamics has been introduced to the analysis of biological data and increasingly
recognized to be functionally relevant. The aim of this study is to evaluate nonlinear and …

Meditation is commonly perceived as an alternative medicine method of psychological
diseases management tool that assist in alleviating depression and anxiety disorders. The …

Meditation is a practice of concentrated focus upon the breath in order to still the mind. In this
paper we have investigated an algorithm to classify rest and meditation, by processing of …

Monitoring the levels of sedation-analgesia may be helpful for managing patient stress on
minimally invasive medical procedures. Monitors based on EEG analysis and designed to …

The aim of this paper is to investigate the performance of time delay neural networks
(TDNNs) and the probabilistic neural networks (PNNs) trained with nonlinear features …

The aim of this study is to describe an evaluation method and measurement methodology for
the study of variations in electroencephalography (EEG) signals in fighter pilots during …

El gráfico de Poincaré es un método no lineal que permite analizar la variabilidad de una
señal, dibujando dicha señal contra ella misma retardada en el tiempo. Aunque este …

Scaling behavior is an indicator of the lack of characteristic time scale, and the existence of
longrange correlations related to physiological constancy preservation. To investigate the …
