The chaotic dynamics of fractional-order systems has attracted much attention recently. Chaotic synchronization is further studied in this paper. We investigate the chaos two identical via a suitable linear controller applied to response system. Based on stability results systems, sufficient conditions for these are given. Control laws derived analytically achieve Chen, Rössler and modified Chua systems. Numerical simulations provided verify theoretical analysis.
The maritime industry is moving towards a digital ecosystem to achieve substantial mutual profits. To this, there have been attempts combine existing, disjointed systems into more efficient, standardized platforms that can be scaled up. However, this transition has faced challenges. address these issues, it suggested innovative technologies such as blockchain utilized due their alignment with the sector’s needs. This study uses triangulation approach by examining mix of literature, web-based...
Data access control is a crucial aspect of data management. Actors who want to share need systems manage consent in order decide can their data. This guarantees the privacy data, which often sensitive. As secure distributed ledger, blockchain widely used today for access. However, not ideal storing large volumes due its characteristics. Therefore, it coupled with off-chain facilitate storage these kinds located outside require security procedures. article proposes securing mechanism based on...
Summary Modern communication networks and social are the main tunnels of knowledge diffusion. Knowledge diffusion in complex is different from epidemic‐like information spreading, because individuals willing to learn spread their friends learning process can hardly be achieved a few conversations. In this paper, we investigate important issue as what topological structure suitable for We propose new model, where both forgetting mechanisms considered. play imparter learner simultaneously....
La prévention des risques et catastrophes est devenue, depuis une trentaine d'années, un enjeu sociétal majeur, ce particulièrement dans les pays développés. Ces préoccupations sont à mettre en relation avec l'envolée pertes financières, l'inégale répartition humaines l'échelle planétaire médiatisation "catastrophiste" de tout évènement. Pour réduire vulnérabilités populations territoires, trois leviers peuvent être utilisés : politiques d'aménagement, le génie civil la formation afin...
The aim of this paper is to present some mathematical results concerning the PCR system (Panic-Control-Reflex), which a model for human behaviors during catastrophic events. This has been proposed better understand and predict reactions individuals facing brutal catastrophe, in context an established increase natural industrial disasters. After stating basic properties, that positiveness, boundedness, stability solutions, we analyze transitional dynamic. We then focus on bifurcation occurs...
This second issue of the French Complex Systems Roadmap is outcome Entretiens de Cargese 2008, an interdisciplinary brainstorming session organized over one week in jointly by RNSC, ISC-PIF and IXXI. It capitalizes on first roadmap gathers contributions more than 70 scientists from major institutions. The aim this to foster coordination complex systems community focused topics questions, as well present challenges sciences complexity science public, political industrial spheres.
The aim of this paper is to contribute the modeling and analysis complex systems, taking into account nature complexity at different stages system life-cycle: from its genesis evolution. Therefore, some structural aspects dynamics are highlighted, leading (i) implement morphogenesis emergent network structures, (ii) control synchronization phenomena within networks. Specific applications proposed illustrate these two aspects, in urban neural
Nash equilibrium is widely present in various social disputes. As of now, structured static populations, such as networks, regular, and random graphs, the discussions on are quite limited. In a relatively stable gaming network, rational individual has to comprehensively consider all his/her opponents' strategies before they adopt unified strategy. this scenario, new strategy emerges system. We define local equilibrium. paper, we an explicit definition for two-strategy games populations....

In a world more and affected by natural and/or industrial disasters, it is essential to understand, analyze control human behavior during such events. The work presented in this article one of the results transdisciplinary collaboration between geographers, psychologists, mathematicians, computer scientists, operational staff stakeholders risk management. This made possible identify diverse behavioral reactions that can occur disaster propose categorization these states their transitions....
This paper introduces the implementation of a computational agent-based financial market model in which system is described on both microscopic and macroscopic levels. artificial used to study response when shock occurs. Indeed, experiences perturbations, systems behavior can exhibit two different properties: resilience robustness. Through simulations scenarios shocks, these properties are studied. The results notably show that emergence collective herding occurs leads temporary disruption...
A Distributed Computing System behaves like a complex network, the interactions between nodes being essentially information exchanges and migrations of jobs or services to execute. The load balancing consists in distributing evenly system nodes. It aims at enhancing resource usage. strategy specifies scenarios for cooperation. Its efficiency depends on quantity, accuracy, distribution available information. But nodes, together with initial network structure, may create different logical...
Current Internet of Things (IoT) development requires service distribution over Wireless Sensor and Actor Networks (WSAN) to deal with the drastic increasing network management complexity. Because specific constraints WSAN, centralized approaches are strongly limited. Multi-hop communication used by WSAN introduces transmission latency, packet errors, router congestion security issues. As it uses local services, a decentralized model avoid long path communications between nodes applications....
