Simulating Critical Infrastructure Cascading Failure
2014 UKSim-AMSS 16th International Conference on Computer Modelling and Simulation, 2014The reliance on critical infrastructures, which are heavily interconnected, is one of society's greatest weaknesses. An individual failure has the potential to have a huge impact on society and affect other infrastructures. Predicting the effects of a cascading failure is a challenge.

The lung water cascade in heart failure
Echocardiography, 2017In heart failure patients, we hypothesize the occurrence of the “lung water cascade,” with the various markers hierarchically ranked in a well‐defined time sequence: (1) early, proximal hemodynamic event with increase in pulmonary capillary wedge pressure; (2) intermediate, direct imaging sign of pulmonary edema (easily detectable at bedside by lung ...

A Markovian Dependability Model with Cascading Failures
IEEE Transactions on Computers, 2009We develop a continuous-time Markov chain model of a dependability system operating in a randomly changing environment and subject to probabilistic cascading failures. A cascading failure can be thought of as a rooted tree. The root is the component whose failure triggers the cascade, its children are those components that the root's failure ...

Cascading failures in coupled map lattices
Physical Review E, 2004Large cascades triggered by initial shocks are common in complex networks. Coupled map lattices have been widely used over the past decades as dynamical models of complex systems. Here we investigate cascading failures in coupled map lattices with different topologies.

Network resilience estimation to cascading failures
2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015Failures of a small fraction of nodes can lead to breakdown of entire network due to overload or congestion. To understand this crucial feature in networks, we propose a load-dependent cascading failure model according to sandpile principle in this paper.

Modeling Cascading Failures in Congested Internet
2008 The 9th International Conference for Young Computer Scientists, 2008Internet is a complex network with the characteristic of self-organized criticality. The cascading dynamics of Internet are presented and two reasons are pointed out, which may cause cascading failures. Different from betweenness centrality, a congestion function to represent the extent of congestion is proposed.

On a new stochastic model for cascading failures
Journal of Applied Probability, 2020AbstractIn this paper, to model cascading failures, a new stochastic failure model is proposed. In a system subject to cascading failures, after each failure of the component, the remaining component suffers from increased load or stress. This results in shortened residual lifetimes of the remaining components.

On the Induction of Cascading Failures in Transportation Networks
2018 IEEE Conference on Decision and Control (CDC), 2018We examine the effect of malicious attacks in disrupting optimal routing algorithms for transportation networks. We model traffic networks using the cell transmission model, which is a spatiotemporal discretization of kinematic wave equations. Here, vehicles are modeled as masses and roads as cells, and traffic flow is subject to conservation of mass ...

Mitigating Cascading Failure with Adaptive Networking
New Mathematics and Natural Computation, 2015The increase of a network connectivity may improve network performance, but at the same time, it may also increase the chance of extremely large risk contagion. If external shocks or excess loads at some agents are propagated to the other connected agents due to failure, the domino effects often come with disastrous consequences.
