Non Linear Heart Rate Variability Study During Pregnancy in Indian Women [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2018
Introduction: Adaptation of Autonomic Nervous System (ANS) in pregnancy can be suitably assessed by Heart Rate Variability (HRV). Non linear methods of HRV better quantify the chaotic dynamics of HRV.

Voluntary Respiration Control: Signature Analysis by EEG

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
The perception of voluntary respiratory consciousness is quite important in some situations, such as respiratory assistance and respiratory rehabilitation training, and the key signatures about voluntary respiration control may lie in the neural signals ...

Computing Entropies with Nested Sampling [PDF]

open access: yesEntropy, 2017
The Shannon entropy, and related quantities such as mutual information, can be used to quantify uncertainty and relevance. However, in practice, it can be difficult to compute these quantities for arbitrary probability distributions, particularly if the probability mass functions or densities cannot be evaluated.

The Entropy of Progressively Censored Samples [PDF]

open access: yesEntropy, 2011
In many life-testing and reliability studies, the experimenter might not always obtain complete information on failure times for all experimental units. Among the different censoring schemes, the progressive censoring scheme has received a considerable attention in the last few years.

Speech Endpoint Detection Based on Multi-scale Sample Entropy and Threshold [PDF]

open access: yesJisuanji gongcheng, 2016
In order to overcome the defect that sample entropy can be falsely detected due to its sensitivity to the suddenly changing noise,this paper proposes a speech endpoint detection algorithm.This algorithm does the multi-scale transform for the speech ...

Analysis of Streamflow Complexity Based on Entropies in the Weihe River Basin, China

open access: yesEntropy, 2019
The study on the complexity of streamflow has guiding significance for hydrologic simulation, hydrologic prediction, water resources planning and management. Utilizing monthly streamflow data from four hydrologic control stations in the mainstream of the
