The rings of (2060) Chiron: Evidence of an evolving system

C. L. Pereira, F. Braga-Ribas, B. Sicardy +54

The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…

Designing Quality Requirements, Metrics and Indicators for Core Ontologies: Results of a Comparative Study for Process Core Ontologies

Luis Olsina, Maria Fernanda Papa, Guido Tebes +1

This preprint specifies quality requirements for a core ontology whose ontological elements such as terms, non-taxonomic relationships, among others, are based on a foundational on…

Enhancement of the flow of vibrated grains through narrow apertures by addition of small particles

Marcos A. Madrid, C. Manuel Carlevaro, Luis A. Pugnaloni +2

We analyze the flow and clogging of circular grains passing through a small aperture under vibration in two dimensions. Via Discrete Element Method simulations, we show that when g…

Differential equation for the flow rate of discharging silos based on energy balance

J. R. Darias, Marcos A. Madrid, Luis A. Pugnaloni

Since the early work of Hagen in 1852 and Beverloo et al. in 1961, the flow rate of granular material discharging through a circular orifice from a silo has been described by means…

Intruder in a two-dimensional granular system: Effects of dynamic and static basal friction on stick-slip and clogging dynamics

C. Manuel Carlevaro, Ryan Kozlowski, Luis A. Pugnaloni +3

We discuss the results of simulations of an intruder pulled through a two-dimensional granular system by a spring, using a model designed to lend insight into the experimental find…
