Exact Coupling Threshold for Structural Transition in Interconnected Networks
Faryad Darabi Sahneh, Caterina Scoglio, Piet Van Mieghem
Interconnected networks are mathematical representation of systems where two or more simple networks are coupled to each other. Depending on the coupling weight between the two com…
Correlation between centrality metrics and their application to the opinion model
Cong Li, Qian Li, Piet Van Mieghem +2
In recent decades, a number of centrality metrics describing network properties of nodes have been proposed to rank the importance of nodes. In order to understand the correlations…
Decentralized Protection Strategies against SIS Epidemics in Networks
Stojan Trajanovski, Yezekael Hayel, Eitan Altman +2
Defining an optimal protection strategy against viruses, spam propagation or any other kind of contamination process is an important feature for designing new networks and architec…
A Topological Investigation of Phase Transitions of Cascading Failures in Power Grids
Yakup Koç, Martijn Warnier, Piet Van Mieghem +2
Cascading failures are one of the main reasons for blackouts in electric power transmission grids. The economic cost of such failures is in the order of tens of billion dollars ann…
Exact Markovian SIR and SIS epidemics on networks and an upper bound for the epidemic threshold
Piet Van Mieghem
Exploiting the power of the expectation operator and indicator (or Bernoulli) random variables, we present the exact governing equations for both the SIR and SIS epidemic models on…
Graph eigenvectors, fundamental weights and centrality metrics for nodes in networks
Piet Van Mieghem
Several expressions for the -th component of the -th eigenvector of a symmetric matrix belonging to eigenvalue and normalized as…
The Impact of the Topology on Cascading Failures in Electric Power Grids
Yakup Koç, Martijn Warnier, Piet Van Mieghem +2
Cascading failures are one of the main reasons for blackouts in power transmission grids. The topology of a power grid, together with its operative state determine, for the most pa…
