On the use of magnetic particles to enhance the flow of vibrated grains through narrow apertures

Autor: C. Manuel Carlevaro, Marcelo N. Kuperman, Sebastián Bouzat, Luis A. Pugnaloni, Marcos A. Madrid

Publikováno v: Granular Matter. 24

The flow of grains through narrow apertures posses an extraordinary challenge: clogging. Strategies to alleviate the effect of clogging, such as the use of external vibration, are always part of the design of machinery for the handling of bulk materi

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

Autor: Luis A. Pugnaloni, Sebastián Bouzat, Marcos A. Madrid, Marcelo N Kuperman, C. Manuel Carlevaro

Publikováno v: Physical Review E. 103

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 grains smaller than the original ones are introduced in the system as a

Transport properties of melanosomes along microtubules interpreted by a tug-of-war model with loose mechanical coupling.

Autor: Sebastián Bouzat, Valeria Levi, Luciana Bruno

Publikováno v: PLoS ONE, Vol 7, Iss 8, p e43599 (2012)

In this work, we explored theoretically the transport of organelles driven along microtubules by molecular motors of opposed polarities using a stochastic model that considers a Langevin dynamics for the cargo, independent cargo-motor linkers and ste

The use of eye-tracking techniques is becoming rapidly extended because of its relevance for acquiring information about cognition and behavior. Recent studies indicate that a correct characterization of the motion of the pupil inside the eyeball is

We characterize the soft modes of the dynamical matrix at the depinning transition, and compare it with the properties of the Anderson model (and long--range generalizations). The density of states at the edge of the spectrum displays a universal lin

Une manière contre-intuitive d'accélérer les écoulements piétons et granulaires à travers une constriction donnant lieu à des blocages: Plus de monde peut-il évacuer plus rapidement ?

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 an original strategy to speed

Behavioral effects in room evacuation models

Autor: Marcelo N. Kuperman, V. Dossetti, Sebastián Bouzat

In this work we study a model for the evacuation of pedestrians from an enclosure considering a continuous space substrate and discrete time. We analyze the influence of behavioral features that affect the use of the empty space, that can be linked t

Pedestrian flows through a narrow doorway: Effect of individual behaviours on the global flow and microscopic dynamics

Publikováno v: Transportation Research Part B: Methodological
Transportation Research Part B: Methodological, Elsevier, 2017

We study the dynamics of pedestrian evacuations through a narrow doorway by means of controlled experiments. The influence of the pedestrians' behaviours is investigated by prescribing a selfish attitude to a fraction c\_s of the participants, while

We study the dynamics of particles in an external anisotropic periodic potential under the influence of additive white Levy noise, in a general not overdamped situation. Different quantities characterizing directionality, coherence and dispersion are
