Massive evaluation and analysis of Poincaré recurrences

Dataset
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, ...

Van't Hoff law for temperature dependent Langmuir constants in clathrate hydrate nanocavities.

Dataset
Collected date : from 2013 to 2014
Creators : Azzedine Lakhlifi

This work gives a set of parameters of van't Hoff law expression for calculating Langmuir constants of different gas species to determine their occupancy in clathrate hydrates in a temperature range 50 – 300 K. The van't Hoff law's parameters are derived from potential energy calculations using a ...
