Double memristors series hyperchaotic system with attractive coexistence and its circuit implementationThe European Physical Journal Special Topics - Tập 230 - Trang 3901-3912 - 2021
Jieyang Wang, Yinghong Cao, Jun Mou, Xingce Liu
In this paper, the sine function memristor and the cosine function memristor are connected in series, and the constructed series memristor is numerically analyzed through its volt-ampere characteristics, and then the new memristor was introduced into the Rossler system to construct a hyperchaotic system with dual memory elements. The coexistence attractor and fractal phenomena in the system are an...... hiện toàn bộ
An overview of memristive cryptographyThe European Physical Journal Special Topics - Tập 228 - Trang 2301-2312 - 2019
Alex Pappachen James
Smaller, smarter and faster edge devices in the Internet of things era demand secure data analysis and transmission under resource constraints of hardware architecture. Lightweight cryptography on edge hardware is an emerging topic that is essential to ensure data security in near-sensor computing systems such as mobiles, drones, smart cameras and wearables. In this article, the current state of ...... hiện toàn bộ
Nonlinear dynamics of galloping-based piezoaeroelastic energy harvestersThe European Physical Journal Special Topics - Tập 222 - Trang 1483-1501 - 2013
A. Abdelkefi, Z. Yan, M.R. Hajj
The normal form is proposed as a tool to analyze the performance and reliability of galloping-based piezoaeroelastic energy harvesters. Two different harvesting systems are considered. The first system consists of a tip mass prismatic structure (isosceles 30° or square cross-section geometry) attached to a multilayered cantilever beam. The only source of nonlinearity in this system is the aerodyna...... hiện toàn bộ
Study of lanthanide liquid-crystalline complexes by Photoacoustic and luminescence spectroscopyThe European Physical Journal Special Topics - Tập 153 - Trang 49-51 - 2008
Yue-tao Yang, Jun-jia Li, Xiao-jun Liu, Shu-yi Zhang
Lanthanide complexes Ln(bta)3L2 (Ln3+: Eu3+, Tb3+ and Ho3+; bta: benzoyltrifluoroacetonate; L: N-octadecyl-2-hydroxy-4-tetradecyloxybenzal- dimine) are synthesized. Their photoacoustic (PA) spectra are reported and interpreted. In the region of ligand absorption, PA intensity increases for Eu(bta)3L2, Tb(bta)3L2 and Ho(bta)3L2, respectively. It is found that the PA intensity of the ligand bears ...... hiện toàn bộ
A new complexity measure for time series analysis and classificationThe European Physical Journal Special Topics - Tập 222 - Trang 847-860 - 2013
Nithin Nagaraj, Karthi Balasubramanian, Sutirth Dey
Complexity measures are used in a number of applications including extraction of information from data such as ecological time series, detection of non-random structure in biomedical signals, testing of random number generators, language recognition and authorship attribution etc. Different complexity measures proposed in the literature like Shannon entropy, Relative entropy, Lempel-Ziv, Kolmogrov...... hiện toàn bộ
The 41Σ+ electronic state of LiCs moleculeThe European Physical Journal Special Topics - Tập 222 - Trang 2329-2333 - 2013
Jacek Szczepkowski, Patryk Jasik, Anna Grochola, Włodzimierz Jastrzȩbski, Józef E. Sienkiewicz, Paweł Kowalczyk
The 41Σ+ state of LiCs molecule is observed experimentally for the first time. The inverted perturbation approach (IPA) method is used to derive the potential energy curve of the state from the measured spectra. The experiment is accompanied by theoretical calculations of adiabatic potentials for excited states in LiCs including 41Σ+, performed with the MOLPRO program package. The irregular shape ...... hiện toàn bộ
The dynamical structure of a hypothetical disc of particles around the asteroid 99942 ApophisThe European Physical Journal Special Topics - - Trang 1-14 - 2023
R. Machado Oliveira, G. Valvano, O. C. Winter, R. Sfair, G. Borderes-Motta
The asteroid 99942 Apophis is a Near Earth Asteroid, which was just recently removed from the Potentially Hazardous Asteroids list, since there is no risk of collision with the Earth for the next 100 years. Although, its importance to dynamical astronomy remains evidenced due to other further close encounters that will happen. In the current work, we analyze the dynamics of a hypothetical disc wit...... hiện toàn bộ
