Though fluid model offers a good approach to nonrigid registration with large deformations, it suffers from the blurring artifacts introduced by the viscosity term. To overcome this drawback, we present an inviscid model expressed in a particle framework. Our idea is to simulate the template image as a set of particles moving towards the target positions. The proposed model can accommodate both...

Abstract The study here is concerned with a thin solid body passing through boundary layer or channel flow and interacting the flow. Relevant new features from modelling, analysis computation are presented along comparisons. Three scenarios of such fluid-body interactive evolution in two-dimensional settings considered turn, namely long translating upstream downstream, little no translation sho...

In this paper we theoretically investigate underlying assumptions that have been used for designing adaptive particle swarm optimization algorithms in the past years. We relate these assumptions to the movement patterns of particles controlled by coefficient values (inertia weight and acceleration coefficient) and introduce three factors, namely the autocorrelation of the particle positions, th...

The presence of wall strengtheners in double-stage electrostatic precipitators affects gas velocity, electrical field and particle movement over the ESP. In this work we have used our previous mathematical model for double-stage ESP {Talaie et. al (2001) [10]] to study the effect of wall strengtheners on the performance of double-stage ESP. One of the important findings was that, due to the fac...

Both cellular motility and intracellular particle movement are compared between normal Dictyostelium amebae of strain AX4 and amebae of a myosin II heavy chain null mutant, HS2215, using the computer assisted "Dynamic Morphology System." In AX4 cells rapidly translocating in buffer, cytoplasmic expansion is apical and the majority of intracellular particles move anteriorly, towards the site of ...
