Stainless steel particles (60 μm in mean diameter) cladded with an alumina shell (2 μm thick and manufactured by mechanofusion) were sprayed with an Ar-H2 (53-7 slm) d.c. plasma jet (I = 500 A, P = 28 kW, th = 56 %). Two main types of particles were collected in flight, as close as 50 mm downstream of the nozzle exit: particles with a steel core with pieces of alumina unevenly distributed at t...

Time-lapsed films of particle motion on the leading lamella of chick heart fibroblasts and mouse peritoneal macrophages were analyzed. The particles were composed of powdered glass or powdered aminated polystyrene and were 0.5-1.0 micrometer in radius. Particle motions were described by steps in position from one frame to the time-lapse movies to the next. The statistics of the step-size distri...

objective: orthodontically induced inflammatory root resorption (oiirr) is considered to be an important sequel associated with orthodontic tooth movement (otm). otm after socket preservation enhances the periodontal condition before orthodontic space closure. the purpose of this study is to investigate the histologic effects of nanobone®, a new highly nonsintered porous nano-crystalline hydrox...

We analyze a partial differential equation that models the two-slit experiment of quantum mechanics. The state variable is probability density function particle positions. has diffusion term corresponding to random movement particles, and nonlocal advection particles in transverse directionperpendicular their forward movement. model compared Schrodinger experiment. supports ensemble interpretat...

Creating realistic animations of water is a challenging problem in the field of computer graphics. To create realistic animations of water, the fluid simulation of the movement of water is necessary. In recent years, attention has been paid to particle-based fluid simulation. Although several methods have been proposed to render the results of the particle-based simulation, there are few method...

This study presents a new evolutionary learning algorithm to optimize the parameters of the neural fuzzy classifier (NFC). This new evolutionary learning algorithm is based on a hybrid of bacterial foraging optimization and particle swarm optimization. It is thus called bacterial foraging particle swarm optimization (BFPSO). The proposed BFPSO method performs local search through the chemotacti...

Three-dimensional microparticle movements induced by laser beams with a funnel- and tubular pod-like structure, in the neighbourhood of the focal plane of an optical trapping setup, are experimentally studied. The funnel and pod beams constructed as coherent superpositions of helical Laguerre-Gaussian modes are synthesized by a computer generated hologram using a phase-only spatial light modula...

The increased nature of email spam with the use of urge mailing tools prompt the need for detector generation to counter the menace of unsolocited email. Detector generation inspired by the human immune system implements particle swarm optimization (PSO) to generate detector in negative selection algorithm (NSA). Outlier detectors are unique features generated by local outlier factor (LOF). The...
