Chaotic dynamical systems are characterized by the existence of a predictability horizon, connected to the notion of Lyapunov time, beyond which predictions of the state of the system are meaningless. In order to study the main features of orbit determination in presence of chaos, Spoto and Milani (2016) applied the classical least squares fit...

Energy efficiency in data centres is addressed through workload management usually to reduce the operational costs and as a by-product, the environmental footprint. This includes to minimise total power consumption or to minimise the power issued from non-renewable energy sources. Hence, the performance requirements of the client's applications...

Knowing the asteroid belt is the key to provide a reliable history ofour solar system. The main question which has been raised in the lastyears is: given our available data, does our classification ofasteroid into families provide a reliable history of the collisionalevolution of our solar system?We have done huge steps forward, but the real...

Since October 2016, the short term (ST) processing of Solar System Objects (SSOs) by Gaia is up and running, and it has produced almost 600 alerts. A crucial point in the chain is the possibility of performing a short arc orbit determination as soon as the object has been detected, which allows the follow up of the object from the ground.The...
