Generating a novel chaotic system by coupling (Rossler-Chen) systems

, 2022
Abstract In this work, a novel chaotic system with a new chaotic behavior is proposed when two chaotic systems (Rossler and Chen) with two different behaviors are combined. The x1, y1 and z1 dynamics of the Rӧssler system was coupled with x2,y2 and z2 dynamics of the Chen system respectively.

Nickel‐Catalyzed LiF‐Rich Interface for Silicon Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Modulating the decomposition of F‐containing species in the electrolyte to form LiF‐rich SEI has been proven to be an effective strategy for interface optimization. Herein, through nickel‐catalyzed pyrolysis of carbon precursors on silicon, graphene‐like carbon was formed to construct three‐dimensional conductive networks.

An encryption algorithm for color images based on an improved dual-chaotic system combined with DNA encoding

Scientific Reports
This study improves the Logistic chaotic system and combines it with the hyperchaotic Chen system to create a dual chaotic system. The algorithm encrypts images in three stages. In the first stage, a plaintext-related key generation scheme is designed to

A general construction method of a new high dimensional multi-wing nested hyperchaotic system [PDF]

AIP Advances
In engineering applications, low-dimensional chaotic systems often suffer from limited complexity and security vulnerability. To address this, a novel and general construction method for a new high-dimensional multi-wing chaotic system was proposed.

Three Birds with One Stone: High‐Performance 2D Lead‐Free Perovskite Solar Cells via Direct In Situ Generation of Organic‐Spacer Precursors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Adopting a “three birds with one stone” strategy, the in situ generation of organic spacer simultaneously addresses three major challenges limiting 2D tin‐based perovskites: (1) Sn2+ oxidation; (2) rapid crystallization; and (3) uncontrolled 2D phase distribution.

Surrogate‐Based Time‐Continuous Seismic Fragility Assessment of Corrosion‐Deteriorated Reinforced Concrete Bridges Under Climate Change

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Seismic fragility assessment of reinforced concrete (RC) bridges exposed to corrosive environments must reliably capture time‐dependent deterioration impacts. Climate change compounds this challenge through nonstationary temperature and humidity variations that accelerate bridge corrosion.

Generalized Synchronization Between Chen System and Rucklidge System

IEEE Access, 2019
This paper investigates the two problems of generalized chaotic synchronization. In one case, the Chen system is treated as the drive system and the controlled Rucklidge system as the response system.

Programmable crack dynamics engineering enables flexible strain sensors with high linearity

FlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

Analysis and synchronization of a novel chaotic system based on Chen's system

Acta Physica Sinica, 2012
In this paper, a new three-dimensional autonomous chaotic system is constructed by adding a product term with variable coefficient to the first equation of Chen's system. The new system with different groups of coefficients can be chaotic or not by adjusting the variable coefficient, that is, by adjusting the variable coefficient, chaos occurs in new ...

Predicting EU Emissions Allowance Prices Using Macroeconomic Indicators and Hybrid AI Models

Journal of Forecasting, EarlyView.
ABSTRACT Predicting carbon allowance prices has grown more crucial in relation to carbon market regulation, financial strategy, and environmental policy development. This study examines a hybrid forecasting system that combines deep learning with ensemble machine learning models to forecast the price fluctuations of EU Emissions Allowance (EUAs) within
