Abstract:

The Chinese stock 300 index (CSI 300) is widely accepted as an overall reflection of the general movements and trends of the Chinese A-share markets. Among the methodologies used in stock market research, the complex network as the extension of graph theory presents an edged tool for analyzing internal structure and dynamic involutions. So, the stock data of the CSI 300 were chosen and divided into two time series, prepared for analysis via network theory. After stationary test and coefficients calculated for daily amplitudes of stock, two “year-round” complex networks were constructed, respec

Abstract:

This paper analyses the structure and characteristics of ubiquitous power Internet of things (UP-IoT) from four levels: the perception layer, network layer, platform layer and application layer. The robustness of UP-IoT is defined from the perspective of system structure, and the internal and external disturbance factors of robustness are analysed. According to the scale-free characteristics of complex network, a robustness evaluation strategy for UP-IoT based on identification of important nodes is proposed. A set of robustness evaluation indexes, including degree centrality, betweenness cent

Abstract:

Spreading Activation is a family of graph-based algorithms widely used in areas such as information retrieval, epidemic models, and recommender systems. In this paper we introduce a novel Spreading Activation (SA) method that we call Vectorised Spreading Activation (VSA). VSA algorithms, like “traditional” SA algorithms, iteratively propagate the activation from the initially activated set of nodes to the other nodes in a network through outward links. The level of the node’s activation could be used as a centrality measurement in accordance with dynamic model-based view of centrality that foc

Abstract:

Traffic is one of the most fundamental dynamical processes in networked systems. With the traditional shortest path routing (SPR) protocol, traffic congestion is likely to occur on the hub nodes on scale-free networks. In this paper, we propose an improved optimal routing (IOR) strategy which is based on the betweenness centrality and the degree centrality of nodes in the scale-free networks. With the proposed strategy, the routing paths can accurately bypass hub nodes in the network to enhance the transport efficiency. Simulation results show that the traffic capacity as well as some other in

Obesity is associated with structural and functional alterations in brain areas that are often functionally distinct and anatomically distant. This suggests that obesity is associated with differences in functional connectivity of regions distributed across the brain. However, studies addressing whole brain functional connectivity in obesity remain scarce. Here, we compared voxel-wise degree centrality and eigenvector centrality between participants with obesity (n=20) and normal-weight controls (n=21).

Abstract:

The theme of regional centrality, more commonly known as accessibility, has been increasingly invoked in recent years, mainly due to a clearer understanding that proximity to the markets is a key determinant of the location of firms. This chapter improves the most standard accessibility index using a decomposition method that allows considering the influence of (1) internal and external factors and (2) economic and geographical aspects. Each component identified has a specific interpretation and allows the identification of policy recommendations, such as the development of the transport and communication networks and active interventions to attract investment. The baseline decomposition method is adjusted in order to incorporate differences in spatial terms among the regional units considered. In order to illustrate the proposed methodology, the authors consider 171 countries. Results lead to the conclusion that the centrality level of the countries analyzed derives from different sources. Therefore, different countries may require different policy interventions to improve their centrality.

Abstract:

In this chapter, the author analyzes the assortativity of real-world networks based on centrality metrics (such as eigenvector centrality, betweenness centrality, and closeness centrality) other than degree centrality. They seek to evaluate the levels of assortativity (assortative, dissortative, neutral) observed for real-world networks with respect to the different centrality metrics and assess the similarity in these levels. The author observes real-world networks are more likely to be neutral (neither assortative nor dissortative) with respect to both R-DEG and BWC, and more likely to be assortative with respect to EVC and CLC. They observe the chances of a real-world network to be dissortative with respect to these centrality metrics to be very minimal. The author also assesses the extent to which they can use the assortativity index (A.Index) values obtained with a computationally light centrality metric to rank the networks in lieu of the A.Index values obtained with a computationally heavy centrality metric.

Abstract:

In this chapter, we explore the use of neighborhood overlap (NOVER), bipartivity index (BPI) and algebraic connectivity (ALGC) as edge centrality metrics to quantify the stability of links for mobile sensor networks. In this pursuit, we employ the notion of the egocentric network of an edge (comprising of the end vertices of the edge and their neighbors as nodes, and the edges incident on the end vertices as links) on which the above three edge centrality metrics are computed. Unlike the existing approach of using the predicted link expiration time (LET), the computations of the above three edge centrality metrics do not require the location and mobility information of the nodes. For various scenarios of node density and mobility, we observe the stability of the network-wide data gathering trees (lifetime) determined using the proposed three edge centrality metrics to be significantly larger than the stability of the LET-based data gathering trees.

The Kirchhoff index, defined as the sum of effective resistances over pairs all of nodes, is of primary significance in diverse contexts of complex networks. In this paper, we propose to use the rate at which the Kirchhoff index changes with respect to the change of resistance of an edge as a measure of importance for this edge in weighted networks. For an arbitrary edge, we explicitly determine the change of the Kirchhoff index and express it in terms of the biharmonic distance between its end nodes, and thus call this centrality as biharmonic distance related centrality (BDRC).

Abstract:

As the content and variety of technology increases in automobiles, the complexity of the system increases as well. Decomposing systems into modules is one of the ways to manage and reduce system complexity. This paper surveys and compares a number of state-of-art components modularity metrics, using 8 sample test systems. The metrics include Whitney Index (WI), Change Cost (CC), Singular value Modularity Index (SMI), Visibility-Dependency (VD) plot, and social network centrality measures (degree, distance, bridging). The investigation reveals that WI and CC form a good pair of metrics that can

Abstract:

Proceeding under the assumption that restorers need to become more involved in the definition of the most advanced management tools for historic buildings, this paper aims to offer a contribution to the “informative” feature of the H-BIM methodology. Indeed, over the past few years, the issues addressed by scholars mostly concerned surveying and modelling techniques, whereas the organization of external data within the virtual model has rarely been considered. The necessity of defining a new operative tool for the maintenance of the wooden chain encircling the dome of Santa Maria del Fiore rep

Abstract:

To reduce the likelihood that R&D projects fail, companies tend to perform collaborative R&D activities in networks. A fundamental characteristic of networks is stability. This paper introduces a novel approach that theoretically determines the stability of R&D networks and combines the analysis of network topology with a two-layer simulation model. Graph theory and measures from social network analysis are used to analyze the topology of collaborative R&D project networks. Our study enables us to identify the companies that play a key role in R&D networks. To ensure the ri

Abstract:

The phrase of “Transition economies”, covering various countries as well as Caucasus and Central Asian Turkic Republics, was found its place in the literature by the 1980’s and this transformation process from the centrally planned economy to market economy was analyzed with economic and fiscal dimension. Undoubtedly, the transition process of these countries wouldn’t be easy and exhibits differences, especially for the Central Asian Turkic Republics, as they were governed under the command economy over many years. Related studies is put forward the increasing importance and future predictions
