Calculating Mean Excitation Energy From Shannon Information Entropy for K–Xe Atoms

International Journal of Modern Physics C, 2003
The calculation of the Shannon entropy of Hartree–Fock electron density is reported for the K–Xe atoms in the fourth and fifth rows of the periodic table in the ground state. In local plasma approximation, the Shannon entropy calculated is used directly to estimate mean excitation energies.

Using S-Transform and Shannon energy for electrical disturbances detection

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
This paper presents a novel method for power quality analysis based on S-Transform. The objective is the detection of certain disturbances that pollute the electrical network such as interruptions, sags and swells. S-Transform provides frequency-dependent resolution while maintaining a direct relationship with the Fourier spectrum.

Shannon Entropy and Correlation Energy for Electrons in Atoms

2018
In this work, we compute Shannon entropy, defined in terms of electron density, for three series of atomic ions including the region of nuclear charges close to the limit at which the ionization potential goes to zero. We use both Hartree–Fock (HF) and quantum Monte Carlo (QMC) densities and we observe a sharp positive deviation of QMC entropy with ...

Shannon entropy for energy technologies ex-ante evaluation

International Journal of Environmental Technology and Management, 2007
Most 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.

Energy—Bandwidth Comparisons and Shannon Theory for Phase Modulation

1986
Neither energy nor bandwidth consumption alone is a sufficient measure of a modulation system. It is a simple matter to reduce the bandwidth of a scheme if large energy is available, and similarly high energy is not needed for a low error probability if a large bandwidth can be tapped.

Application of wavelet transform and Shannon energy on R peak detection algorithm

2016 13th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2016
The R peak detection algorithm is a necessary tool for monitoring and diagnosing the cardiovascular disease. This paper presents the R peak detection algorithm based on continuous wavelet transform (CWT) and Shannon energy. We evaluate the proposed algorithm with the ECG data record 108 from MIT-BIH arrhythmia database.

ECG arrhythmia classification based on variational mode decomposition, Shannon energy envelope and deterministic learning

International Journal of Machine Learning and Cybernetics, 2021
Electrocardiography (ECG) signals play an important role in the cardiac disorder diagnosis and arrhythmia detection since they reflect all the electrical activities of the heart and include information about heart function and heart conditions. Due to the subtle alterations in the amplitude, duration and morphology of the ECG, the development of ...

A Robust Method to Reliable Cardiac QRS Complex Detection Based on Shannon Energy and Teager Energy Operator

Circuits, Systems, and Signal Processing, 2020
The QRS complex is considered to be one of the main factors in diagnosing heart diseases; thus, its detection on the electrocardiogram signals has become the target of various types of research. The primary aim of this study is to design and develop a novel technique for QRS complex detection under various ECG signal morphologies and different QRS ...
