Probabilistic risk assessment provides a practical approach for assessing the security capabilities of systems. Terrorism risk assessment requires estimation of the probabilities and consequences ofâ€¦ (More)

Monitoring an electrical network is an important and challenging task. Phasor measurement units are measurement devices that can be used for a state estimation of this network. In this paper weâ€¦ (More)

We study in this paper the problem of finding in a graph a subset of k edges whose deletion causes the largest increase in the weight of a minimum spanning tree. We propose for this problem anâ€¦ (More)

Modelling and simulation techniques offer a comprehensive method for assessing the impact of a terrorist attack, allowing multiple scenarios to be simulated with ease without imposing extensive timeâ€¦ (More)

We study a class of bilevel binary linear programs with lowerlevel variables in the upper-level constraints. Under certain assumptions, we prove that the problem can be reformulated as a single-levelâ€¦ (More)
