TL;DR: A vehicle-centric probabilistic approach to virtual cell management in ultra-dense 5G networks as proposed allows more assertive virtual cell selection, improving the services offered by IoV through the5G networks.
Abstract: The fifth generation (5G) cellular networks tend to be ultra-dense networks (UDN). Among the 5G UDN challenges, it is the creation and the management of virtual cells centered on the user. By the literature was not found any work that has directly associated a vehicle-centric probabilistic approach to virtual cell management in ultra-dense 5G networks as proposed in this paper as a contribution to the technological development on 5G networks use, what indicates its originality. Considering scenarios involving high mobility, such as the Internet of Vehicles (IoV) or vehicle-to-network (V2N) communications, this challenge becomes even greater. For this purpose, this article presents a virtual cell selection probabilistic approach focused on V2N communications. All the processing based on speed criteria and complex network metrics is performed inside a controller that is required to manage the virtual cells. The motivation to use different metrics of radio masts is that one has physical applications as an algebras operator in purely mathematical contexts, while others find wide application in network theory. Simulations were performed through the Network Simulator ns3. The results show that the proposed approach allows more assertive virtual cell selection, improving the services offered by IoV through the 5G networks.

TL;DR: The current study provides the possibility of merging Laclau and Mouffe’s theory of discourse analysis with network theory to specify an alternative bedstead for studying discourse via a semi-automatic algorithm and indicates that the approach is strong enough to pave a way for studying the articulation of the discourse from an alternative view.
Abstract: The current study provides the possibility of merging Laclau and Mouffe’s theory of discourse analysis with network theory to specify an alternative bedstead for studying discourse via a semi-automatic algorithm. To do so, first, considering the text as the discourse of complex system, a semi-automatic algorithm is implemented to transform the interacting linguistic components into a network which is depicted as a graph of vertices connected by edges. Then, some of the graph statistics, e.g. degree, weighted degree, eigenvector centrality, etc., are identified for characterizing the nodes as moments, nodal points, and/or nodal point of identity. Finally, the articulation of the discourse based on the above-mentioned components is studied. The results indicate that the approach is strong enough to pave a way for studying the articulation of the discourse from an alternative view, especially based on Laclau and Mouffe’s theory of discourse analysis.

TL;DR: In this paper , the structure of the European Airport Network (EAN) using concepts from complex network theory by utilising 2019 passenger data collected from Eurostat was revealed by computing connectivity and centrality measures and their correlations.
Abstract: ABSTRACT This study aims to reveal the structure of the European Airport Network (EAN) using concepts from complex network theory by utilising 2019 passenger data collected from Eurostat. Initially, the EAN was explored by computing connectivity and centrality measures and their correlations. The community structure of the EAN was also examined by modularity maximisation using the relatively new Leiden algorithm. When the network was compared with simulated models, it was observed that the EAN had small-world and scale-free properties. To measure the hub performance of the airports, their binary betweenness centrality was compared with a weighted betweenness measure employing the ratio of geographical distance to passenger traffic between the nodes. A significant difference was observed between the two centrality measures.
