Granular material flowing through bottlenecks, like the openings of silos, tend to clog and thus inhibit further flow.We study this phenomenon in a three-dimensional hopper for spherical and shape-anisotropic particles by means of x-ray tomography.The x-ray tomograms provide information on the bulk of the granular 30hh bikini filling, and allows us

An energy transition is needed in order to meet the European pledge of reaching climate neutrality by 2050.This transition cannot ignore the renewable resources available from 70% of read more the Earth (namely, the oceans and seas).This concept is fundamental for the planet, especially for the Mediterranean area.Marine renewable energies are still

Graph signal sampling has been widely studied in recent years, but the accurate signal models required by most of the existing sampling methods are usually unavailable prior to any observations click here made in a practical environment.In this paper, a sequential sampling and estimation algorithm is proposed for approximately bandlimited graph sig
