City path tomography: reconstructing square road network from artificial users mobile phone data
Andy Rodriguez Lorenzo, Alejandro Lage-Castellanos
Population mobility can be studied readily and cheaply using cellphone data, since people's mobility can be approximately mapped into tower-mobile registries. We model people movin…
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 inference in water distribution networks
