Complex dynamics and nonlinear systems play a critical role in industrial processes, where complex interactions, high uncertainty, external disturbances can significantly impact efficiency, stability, safety. In sectors such as mining, manufacturing, energy networks, even small perturbations lead to unexpected system behaviors, operational inefficiencies, or cascading failures. Understanding controlling these is essential for developing robust, adaptive, resilient systems. This study conducts systematic literature review covering 2015–2025 Scopus Web of Science, initially retrieving 2628 (Scopus) 343 (WoS) articles. After automated filtering (Python) applying inclusion/exclusion criteria, refined dataset 2900 references was obtained, from which 89 highly relevant studies were selected. The categorized into six key areas: (i) heat transfer with magnetized fluids, (ii) control, (iii) big-data-driven optimization, (iv) transition via SOEC, (v) fault detection control valves, (vi) stochastic modeling semi-Markov switching. Findings highlight the convergence robust machine learning, IoT, Industry 4.0 methodologies tackling challenges. Cybersecurity sustainability also emerge factors models, alongside barriers limited data availability, platform heterogeneity, interoperability gaps. Future research should integrate multiscale analysis, deterministic chaos, deep learning enhance adaptability, security, efficiency operations high-complexity environments.

Abstract Multi-scroll chaos exhibits complex dynamic behavior, the method of designing chaotic systems with multi-scroll attractor is an important research topic. Without any theoretical guidance, it very difficult to obtain a new system, especially system. In this paper, class n -scroll investigated by using variable transformation based on th order polynomial number. The Lyapunov exponent, bifurcation diagram, and topological horseshoe in Poincar é cross-section are presented rigorously prove existence system assistance computer simulation. Based proposed encryption algorithm for image information, simulation experiments verify feasibility effectiveness algorithm.

Multistability via field-enhanced carrier dynamics in a single-gap nonlinear terahertz split-ring resonator with loss parameter control

Physical review. E, Год журнала: 2025, Номер 111(4)

Опубликована: Апрель 14, 2025

Metasurfaces, artificial materials with unique electromagnetic (EM) properties arising from electron oscillations in highly conductive metals, often utilize split-ring resonators (SRRs) as key components for nonlinear effects. In this paper, we investigate the phenomena caused by charge carrier motion at gap of a single SRR operating terahertz (THz) frequency range. Unlike previous approaches, our model incorporates an additional controlled field to adjust loss parameter, providing more generalized framework understanding behavior SRRs. The dynamics are revealed two-parameter space diagrams, which allow us identify periodic and chaotic different parameter sets material. order explore multifunctionality material, construct two-dimensional diagrams sweeping each two directions same initial values find plethora hysteresis regions, demonstrating interesting phenomenon multistability. Our results show that occurs extremely large dynamic regions all cases studied, favoring coexistence up three signals/attractors. types multistable patterns studied cross-section demarcation region presented states, only states. We analyze parallel branches branch some range where bifurcation presents jump. According results, has impact on multistability, since it increases number coexisting However, appears very tiny parameters annihilates after collision crisis. Finally, influence material using spatial control can gradually eliminate presence behavior, thus serving pivotal mechanism future applications.
