A counterintuitive way to speed up pedestrian and granular bottleneck flows prone to clogging: can 'more' escape faster?
(IOP Publishing, 2018-08)
Dense granular flows through constrictions, as well as competitivepedestrian evacuations, are hindered by a propensity to form clogs. We use simulations of model pedestrians and experiments with granular disks to explore ...
Slow relaxation dynamics of clogs in a vibrated granular silo
(American Physical Society, 2018-04)
We experimentally explore the vibration-induced unclogging of arches halting the flow in a two-dimensional silo. The endurance of arches is determined by carrying out a survival analysis of their breaking times. By analyzing ...
Granularidad de datos bajo la perspectiva de información y tecnología: Una interpretación de la Ciencia de la InformaciónDado e granularidade na perspectiva da informação e tecnologia: Uma interpretação pela ciência da informação
(2013-01-01)
The rapid development of technological resources and their use in data access, information use and knowledge generation processes demand from Information Science (IS) a revision and broadening of its referential framework ...
Relaxation processes after instantaneous shear-rate reversal in a dense granular flow
(2015)
A numerical model of granular material at different packing fractions and under steady shear is submitted to a sudden shear reversal. We monitor consequences of the strong density and shear rate spatio-temporal heterogeneities, ...
