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, ...
DCF77 time of flight measurement
Collected date : from 1 Nov 2016 ongoing
Creators :
Jean-Michel Friedt
DCF77 is a Very Low Frequency (VLF) emitter located in Mainflingen, Germany, about 400 km away from Besançon, France. The objective of the collected data is to measure the time of flight of the 77.5 kHz signal with respect to GPS 1 PPS used as reference, and assess the dependence with ionospheric ...
