Analysis of Metal Cutting Acoustic Emissions by Time Series Models
F. Polito, A. Petri, G. Pontuale +1
We analyse some acoustic emission time series obtained from a lathe machining process. Considering the dynamic evolution of the process we apply two classes of well known stationar…
Brownian ratchet in a thermal bath driven by Coulomb friction
A. Gnoli, A. Petri, F. Dalton +4
The rectification of unbiased fluctuations, also known as the ratchet effect, is normally obtained under statistical non-equilibrium conditions. Here we propose a new ratchet mecha…
Stochastic dynamics of a sheared granular medium
Alberto Petri, Andrea Baldassarri, Fergal Dalton +3
We experimentally investigate the response of a sheared granular medium in a Couette geometry. The apparatus exhibits the expected stick-slip motion and we probe it in the very int…
Flow of autonomous traffic on a single multi-lane street
Federico Polito, Fergal Dalton
We investigate the behaviour of an original traffic model. The model considers a single multi-lane street, populated by autonomous vehicles directed from either end to the other. L…
Shear stress fluctuations in the granular liquid and solid phases
Fergal Dalton, Francis Farrelly, Alberto Petri +3
We report on experimentally observed shear stress fluctuations in both granular solid and fluid states, showing that they are non-Gaussian at low shear rates, reflecting the predom…
Brownian forces in sheared granular matter
Andrea Baldassarri, Fergal Dalton, Alberto Petri +3
We present results from a series of experiments on a granular medium sheared in a Couette geometry and show that their statistical properties can be computed in a quantitative way…
