A ROBUST QRS COMPLEX DETECTION METHOD BASED ON SHANNON ENERGY ENVELOPE AND HILBERT TRANSFORM
Journal of Mechanics in Medicine and Biology, 2022QRS complex detection plays an important role in electrocardiogram (ECG) automatic analysis. The accuracy and robustness of the detection algorithm greatly affect its practicability. However, the existing detection algorithms are greatly affected by ECG signal quality, and some detection algorithms cannot even work properly due to the poor signal ...

R-Peaks Detection Using Shannon Energy for HRV Analysis
2018In this paper, a system for R-peak detection in ECG signal is presented that applicable in different heart rate variability (HRV) applications based on S-transform and Shannon energy. The presented technique and system are efficient in R-peak detection as per results illustrated up to 99.80% of sensitivity and positive predictivity.

QRS complex detection using fractional Stockwell transform and fractional Stockwell Shannon energy
Biomedical Signal Processing and Control, 2019Abstract QRS complex present in Electrocardiogram (ECG) is the most vital component which is used as a basis for determining the condition of a human heart. However, due to the non-stationary nature of ECG, QRS detectors are unable to accurately delineate the R-peaks which may result in significant false negatives and false positives. So, in order to

1/Z expansion, correlation energy, and Shannon entropy of heavy atoms in nonrelativistic limit
International Journal of Quantum Chemistry, 1998It has been known since the work of March and White that the simplest nonrelativistic density functional theory, namely, the statistical method of Thomas, Fermi, and Dirac, sums subseries of the so-called 1/Z expansion to yield, for heavy neutral atoms, the ground-state energy E= − a0Z7/3+ a1Z2−a2Z5/3+⋅⋅⋅.

R Peak Detection using Empirical Mode Decomposition with Shannon Energy Envelope
2018 Second International Conference on Inventive Communication and Computational Technologies (ICICCT), 2018R peak is an important parameter of ECG for monitoring the cardiac health. In this paper we present R peak detection algorithm from electrocardiogram (ECG) signal using Empirical Mode Decomposition (EMD) with combination of Shannon Energy Envelope. In this algorithm the ECG signal is decomposed by using the EMD and for highlighting the QRS complex we ...

Comparison of Fetal Heart Rate Detection Using Envelope Extraction and Shannon Energy
2019 International Seminar on Application for Technology of Information and Communication (iSemantic), 2019Heart rate monitoring is widely used as a general procedure to examine fetal health condition. Fetal heart rate can be used to identified possibilities of fetal anomaly and warn the obstetrician to provide immediate intervention before any further abnormalities. The purpose of this research is to compare fetal heart rate detection result using envelope

Shannon Entropy and Information Theory for Energy Technology ex-ante evaluation
2007Most of the international literature has used Shannon entropy to measure the information gap. In this paper we propose a method that uses Shannon entropy to evaluate ex-ante energy technologies in a decision making process. It was called ITEM, i.e., Information Theory Energy technology ex-ante evaluation Method.

2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017
Protecting plantation forests from pests and diseases are essential for keeping trees healthy and productive. Diagnosis of diseases is critical for disease management in plantation forests. For forest plantation with large concession areas, manual identification is time consuming and subjective due to inconsistency of investigator's decision.

Heart sound detection based on wavelet transform and Shannon energy envelope
Valvular heart diseases contribute significantly to global morbidity, making phonocardiography (PCG) an essential non-invasive diagnostic tool. However, the detection of heart sounds (S1 and S2) is frequently hindered by the presence of pathological murmurs and instrumentation noise. This paper proposes an algorithm for the detection of S1 and S2 heartJOAO VITOR DE AMORIM PAULA +1 more
