Discharge of elongated grains from silo with rotating bottom
Kiwing To, Yi-Kai Mo, Tivadar Pongó +1
We study the flow of elongated grains (wooden pegs of length =20 mm with circular cross section of diameter =6 and 8 mm) from a silo with a rotating bottom and a circular o…
Labelling Drifts in a Fault Detection System for Wind Turbine Maintenance
Iñigo Martinez, Elisabeth Viles, Iñaki Cabrejas
A failure detection system is the first step towards predictive maintenance strategies. A popular data-driven method to detect incipient failures and anomalies is the training of n…
Forecasting VaR and ES using a joint quantile regression and implications in portfolio allocation
Luca Merlo, Lea Petrella, Valentina Raponi
In this paper we propose a multivariate quantile regression framework to forecast Value at Risk (VaR) and Expected Shortfall (ES) of multiple financial assets simultaneously, exten…
Flow in an hourglass: particle friction and stiffness matter
Tivadar Pongó, Viktória Stiga, János Török +5
Granular flow out of a silo is studied experimentally and numerically. The time evolution of the discharge rate as well as the normal force (apparent weight) at the bottom of the c…
