Spiral Particle Distribution for Template based Tracking

This paper presents a new approach for tracking template-based objects based on spiral particle distribution algorithm. Proposed algorithm uses points on Archimedean spiral as possible location of object in next frame. Before applying algorithm, the system is provided with off-line learning of training data. After that, start point is initialized and algorithm for tracking is applied.

Spiral: Influence of particle size distribution on the

2021-2-5 · The results show that even for soils with continuous particle size distributions, a significant proportion of the finer particles may not transmit stress and be inactive. Drawing on ideas put forward in relation to gap-graded soils, both a mechanical void ratio and mechanical bulk density that consider the inactive grains as part of the void space are determined.

Investigations into the spiral distribution of the

2018-4-1 · According to Eqs. (29a)and (30a), two variables control the heliostat field distribution in the spiral distribution ‘a’ and ‘b’. The values of these variables are obtained for maximizing field annual weighted efficiency. The PSO algorithm is used to optimize ηh_w(a,b), a swarm of particles is assumed.

A description of the full-particle-orbit-following

2013-1-21 · When individual orbits are calculated with SPIRAL as shown in section 2 the position and velocity of the particle are written in the output file as a function of time together with the magnetic electric and fields and the poloidal flux at the particle location which is sufficient to obtain various other quantities that are important for the fast particle dynamics. When ensembles of fast ions are calculated it is impossible to store information for each orbit

Numerical Simulation of Particle Dynamics in a Spiral

Spiral jet mills are ubiquitous in the pharmaceutical industry. Breakage and classification in spiral jet mills occur due to complex interactions between the fluid and the solid phases. The study of these interactions requires the use of computational fluid dynamics (CFD) for the fluid phase coupled with discrete element models (DEM) for the particle phase.

Simulation of particle-laden flow in a Humphrey spiral

2017-10-1 · We also analyzed the particle distribution profile and grade recovery, and the results are shown in Fig. 6. As seen from the results, for ψ > 10 °, there is a clear falloff in the particle separation efficiency. On the other hand, the increase in the separation efficiency is insignificant when ψ decreases from 9° to 7.7°. The residual fraction that remained inseparable is attributed mainly to size effects or
