Models for information propagation on graphs
Oliver R. A. Dunbar, Charles M. Elliott, Lisa Maria Kreusser
We propose and unify classes of different models for information propagation over graphs. In a first class, propagation is modelled as a wave which emanates from a set of \emph{kno…
Binary recovery via phase field regularization for first traveltime tomography
Oliver R. A. Dunbar, Charles M. Elliott
We propose a double obstacle phase field methodology for binary recovery of the slowness function of an Eikonal equation found in first traveltime tomography. We treat the inverse…
Phase field modelling of surfactants in multi-phase flow
Oliver R. A. Dunbar, Kei Fong Lam, Bjorn Stinner
A diffuse interface model for surfactants in multi-phase flow with three or more fluids is derived. A system of Cahn-Hilliard equations is coupled with a Navier-Stokes system and a…
