Simulations of Infectious Disease Propagation

Network structural dynamics and infectious disease propagation.

We aimed to relate dynamic changes in risk-network (sex and/or injecting drug) structure to observe STD/HIV transmission. We analysed macro- and micro-structural elements in 2 heterosexual networks, augmented by ethnographic observations. In a Colorado cohort of injecting drug users (n = 595), measures of subgroup formation and of density of activity show decrease of network cohesion over time;...

Modeling the Propagation of Infectious Disease as a Connected Network

A pandemic is likely to occur in the near future, and this could cause significant disruptions in the human population. Avian influenza is such an example, as it can potentially evolve to transmit from human to human, and spread very fast to become a world-wide epidemic in very a short period of time. In order to prepare for such a disaster and to develop global mitigation strategies for societ...

Hydraulic fracture propagation: analytical solutions versus Lattice simulations

In this work, we used a grain-based numerical model based on the concept of lattice. The modelling was done to simulate the lab experiments carried out on the mortar samples. Also the analytical solutions corresponding to the viscosity-dominated regime were used to estimate the fracture length and width, and the results obtained were compared with the numerical simulations. As the analytical so...
