As global energy demand increases, photovoltaic power generation has become the solution to conundrum. Based on product trade data from 2000 2023, this paper examines development of industry chain pattern and impact PageRank centrality top 10% node failures network vulnerability. It accomplishes by employing hypothetical assault strategies intricate networks. Research shown that: ① The PV undergone profound changes. trend multipolarization is becoming more obvious. China's position in each...

The couplings among different networks facilitate their communications, while at the same time they also bring risk of enhancing wide spread cascading failures to coupled networks. Given that there is usually time-delay during and more than one coupling link a node might possess, failure model for scale-free multi-coupling-link built in this paper, based on map lattices (CML) model, which may be wider representative previous models. Our research shows BA (Barabási-Albert) networks, threshold...

The study of load-induced cascading failures in interdependent networks is great realistic significance, which can provide valuable reference for designing high robust network or improving their robustness. In this paper, we establish a model double layer network, and the effects contributions inter-degree intra-degree to loads, coupling, intra-node linking similarity on failure network. Our studies show that when loads attain some values, reaches highest robustness against failures. As...

Mastering its law is great meaning to understand relationship between upstream and downstream chain market investment. This article uses time series daily closing prices stocks global past ten years as research object. Granger causality test network theory were used construct risk industrial chain. We have identified key fluctuation obtained path fluctuation. According...

This paper aimed at the chaotic synchronization ability of complex networks with different structures whose nodes have orders. Problems network and biological application are introduced firstly. And then, we studied orders structures. Based on Lyapunov stability theory, coupling function connecting is identified. Numerical simulation results were used to compare three kinds So, certain phenomena can be explained due our research.

Revealing how the interdependency between different networks affects load-induced cascading failures is a new interesting topic recently. A failure model for interconnected network system introduced in this paper, which loads of failed nodes can be transmitted layer or among each network, ratio adjusted with defined parameter [Formula: see text] viewed as measure coupling strength. Based on proposed model, we find that under attacking strategies and value text], types have effects robustness...

Recently the robustness of coupled network under cascading failure has attracted a lot attention. In this paper, we investigate interconnected weighted networks based on state link. The load one link is defined by function strength two nodes at ends that link, using four intentional attack strategies, study invulnerability when occurs. Our studies show with highest attacked, damage to will be more serious attacking inner-link than caused coupling load, and no matter how links distribute,...

In order to study the influence of network’s structure on cooperation level repeated snowdrift game, in frame two kinds topologically alterable network models, relation between density and topological parameters was researched. The results show that is correlated reciprocally with power-law exponent positively average clustering coefficient; other words, more homogenous less clustered a network, lower level; degree nonmonotonic; when deviates from optimal value, drops.

It is well observed that some infectious diseases show a feature of periodicity; is, the disease may prevail during certain season and vanish afterwards. In effort understanding this specific phenomenon, in paper, we propose spreading model with time-variant infectivity function considering both features periodicity agent variability. We apply modified to scale-free network frame tunable power-law coefficient find out characteristics periodic dynamics. Our work consists theoretical...

To study the trade characteristics and important trends of leading countries in conventional energy networks, this paper uses data on coal, oil natural gas based complex network theory; constructs a comprehensive directed weighted network; analyzes relations, volume, betweenness centrality groups China, United States, Russia Saudi Arabia. The results show that import export relations exhibit power-law distribution, but four are developing toward diversified trading partners. States has...

Detecting communities in complex networks is of considerable importance for understanding both the structure and function networks. In this paper, we propose an algorithm community detection. The fuzzy relational model established by using global topology information, then based on proposed model, number determined adopting spectral analysis partition network realized combining with clustering. correctness verified computer-generated different sizes real results showed that combination...

Cascading failures in isolated networks have been widely studied the past decade, cascading interdependent are attracting more and attention recently, but previous studies focus on topological effects, neglecting loads which present most real networks. Considering effect of loads, two-layered BA network model failure were reestablished this paper, based these, robustness under random intentional attacks effects average degree suppressing researched. The simulation results show that compared...

In order to investigate the effects of community structure on synchronization, a pinning control strategy is researched in class complex networks with this paper. A feedback law designed based network information. The stability condition given and proved by using Lyapunov theory. Our research shows that as networks, there being threshold h T ≈ 5, when coupling strength bellows threshold, stronger corresponds higher synchronizability; vice versa, brings lower synchronizability. addition...
