Massive evaluation and analysis of Poincaré recurrences
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, ...
Pure liquid phase recovery in karstic medium
This project is about the study in 2D-cells of fractured media, contaminated by pure phase hydrocarbons. Cosidered systems are made of 3 non-miscible fluids (air, water and hydrocarbons), considering light and dense hydrocarbons. First, the fluids behavior and the distribution of contaminants were ...
BDB - Binary star DataBase
The Binary star DataBase (BDB) is the database of binary/multiple stellar systems of various observational types. BDB contains data on physical and positional parameters of 260,000 components of 120,000 stellar systems of multiplicity 2 to more than 20, taken from a large variety of published ...
