Dynamics of epidemic models from cavity master equations
Ernesto Ortega, David Machado, Alejandro Lage-Castellanos
We apply the cavity master equation (CME) approach to epidemics models. We explore mostly the susceptible-infectious-susceptible (SIS) model, which can be readily treated with the…

Contamination Source Detection in Water Distribution Networks using Belief Propagation
Ernesto Ortega, Alfredo Braunstein, Alejandro Lage-Castellanos
We present a Bayesian approach for the Contamination Source Detection problem in Water Distribution Networks. Given an observation of contaminants in one or more nodes in the netwo…

Contamination source inference in water distribution networks
Alfredo Braunstein, Alejandro Lage-Castellanos, Ernesto Ortega
We study the inference of the origin and the pattern of contamination in water distribution networks. We assume a simplified model for the dyanmics of the contamination spread insi…
