Wang, X. (author), Koc, Y. (author), Kooij, R.E. (author), Van Mieghem, P. (author)Cascading failures are one of the main reasons for blackouts in electrical power grids. Stable power supply requires a robust design of the power grid topology. Currently, the impact of the grid structure on the grid robustness is mainly assessed by purely topological metrics, that fail to capture the fundamental properties of the electrical...conference paper 2015

Wang, X. (author), Koç, Y. (author), Derrible, S. (author), Nasir Ahmad, Sk. (author), Kooij, R.E. (author)Metros (heavy rail transit systems) are integral parts of urban transportation systems. Failures in their operations can have serious impacts on urban mobility, and measuring their robustness is therefore critical. Moreover, as physical networks, metros can be viewed as network topological entities, and as such they possess measurable network...conference paper 2015

Wang, X. (author)Cities in China are embarked on ambitions plans to create renewed inner-city station areas, particularly evident after a series of redevelopment projects; these projects mainly focus on the development of transport infrastructures, rather than turning station areas into vibrant urban spaces. Therefore, a general lack of citizen’s daily...conference paper 2014

Wang, X. (author)Redevelopments of Chinese inner-?city station areas introduced both new transport infrastructures (high speed railway, urban mass transit system, etc.) and real estate projects to station vicinities during the past decades. However, existing station areas are isolated from the rest of the city, and seldom urban activities take place in station...conference paper 2014

Winterbach, W. (author), Wang, H. (author), Reinders, M. (author), Van Mieghem, P. (author), De Ridder, D. (author)Biological networks exhibit intriguing topological properties such as small-worldness. In this paper, we investigate whether the topology of a metabolic network is related to its robustness. We do so by perturbing a metabolic system in silico, one reaction at a time and studying the correlations between growth, as predicted by flux balance...conference paper 2010

Li, C. (author), Wang, H. (author), Van Mieghem, P. (author)The largest eigenvalue ? 1 of the adjacency matrix powerfully characterizes dynamic processes on networks, such as virus spread and synchronization. The minimization of the spectral radius by removing a set of links (or nodes) has been shown to be an NP-complete problem. So far, the best heuristic strategy is to remove links/nodes based on the...conference paper
