Model for the Growth of the World Airline Network

We propose a probabilistic growth model for transport networks which employs a balance between popularity of nodes and the physical distance between nodes. By comparing the degree of each node in the model network and the WAN, we observe that the …

Knowing Power Grids and Understanding Complexity Science

Complex networks theory has been well established as a useful framework for studying and analysing structure, dynamics and evolution of many complex systems. Infrastructural and man-made systems like power grids, gas and water networks and the …

Context-Independent Centrality Measures Underestimate the Vulnerability of Power Grids

Power grids vulnerability is a key issue in society. A component failure may ntrigger cascades of failures across the grid and lead to a large blackout. nComplex network approaches have shown a direction to study some of the problems nfaced by power …

Revealing the Structure of the World Airline Network

Resilience of most critical infrastructures against failure of elements that appear insignificant is usually taken for granted. The World Airline Network (WAN) is an infrastructure that reduces the geographical gap between societies, both small and …
