In this project, a commercial membrane exhibiting low performances of heavy metal removal has been modified by plasma grafting of poly(allylamine). This treatment allows modifying the structural and physicochemical properties of the membrane surface and thus increasing separation performances, while ...
Massive evaluation and analysis of Poincaré recurrences
Disciplines :
physics, mathematical
astronomy & astrophysics
Collected date : from 2018 ongoing
We present a novel numerical method aimed to characterize global behaviour, in particular chaotic diffusion, in dynamical systems. It is based on an analysis of the Poincaré recurrence statistics on massive grids of initial data or values of parameters. We concentrate on Hamiltonian systems, ...
