This paper presents a proficiently developed resampling algorithm for particle filtering. In any filtering algorithm adopting the perception of particles, especially in visual tracking, resampling is an essential process that determines the algorithm’s performance and accuracy in the implementation step. It is usually a linear function of the weight of the particles, which determines the number...

In this research, the efficiency of the comminution circuit as well as the efficiency of size classification equipment of the concentrator plant 2 of Sarcheshmeh copper complex was studied. The comminution circuit of this plant includes one SAG mill in a closed circuit with a vibrating screen and one ball mill with a size classification system of hydrocyclone. The goal of this work was to calcu...

The effects of vibration parameters, operating conditions and material properties on bed voidage were investigated using an optical fiber probe approach in a vibrating fluidized bed with a diameter of 148 mm. Variables studied included frequency (0-282 s), amplitude (0 mm-1 mm), bed height (0.1 m-0.4 m) as well as four kinds of particles (belonging to Geldart's B and D groups). The axial and ra...

in this paper, we study different methods of solving joint redundancy-availability optimization for series-parallel systems with multi-state components. we analyzed various effective factors on system availability in order to determine the optimum number and version of components in each sub-system and consider the effects of improving failure rates of each component in each sub-system and impr...

A vibrating membrane module currently marketed for ®ltration applications was evaluated for the separation of volatile organic compounds (VOCs) from aqueous solutions by pervaporation. Preliminary screening experiments with three VOCs, three silicone membranes, and in the presence and absence of a surfactant were performed to determine if further consideration of the vibrating module for a ®eld...

Large-scale collective motion emerging in a monolayer of vertically vibrated elongated particles is studied. The motion is characterized by recurring swirls, with the characteristic scale exceeding several times the size of an individual particle. Our experiments identified a small horizontal component of the oscillatory acceleration of the vibrating plate in combination with orientation-depend...

We investigate the liquid-solid transition of two-dimensional hard spheres in the presence of gravity. We determine the transition temperature and the fraction of particles in the solid regime as a function of temperature via event-driven molecular-dynamics simulations and compare them with the theoretical predictions. We then examine the configurational statistics of a vibrating bed from the v...

A 3.3 kJ pulsed plasma focus device (NX2) was used to deposit magnetic CoPt nano-particles on Si (100) substrates at a low charging voltage of about 8kv. The hydrogen was used as filling gas at different gas pressures (2, 4, 6, and 8 mbar) to investigate the morphological, structural and magnetic properties of nanostructure thin films, using scanning electron microscopy (SEM), X-ray diffraction...

The ignition of electrically heated boron filaments in air and argon/oxygen mixtures has been studied. Boron filament resistance, temperature, and emissions from the BO and BO2 bands were monitored. Preliminary experimental data have also been obtained to characterize the phases formed inside burning boron particles produced and ignited from the same filament material by feeding a vibrating bor...

A discrete and periodic complex Ginzburg-Landau equation, coupled to a mean is systematically derived from driven dissipative lattice oscillator model, close the onset of supercritical Andronov-Hopf bifurcation. The model inspired by recent experiments exploring active vibrations quasi-one-dimensional lattices self-propelled millimetric droplets bouncing on vertically vibrating fluid bath. Our ...
