Based on the particle velocity PDF equations of the particle’s stochastic motion,the statistics character-istic of particle velocity is got by using the analytic solution of particle velocity PDF equation,then solve particle trajectory by calculating the new location of particle.
The chaotic research on the signal of the main body motion and on the whole fluctuation signal(filtered the high frequency measure noise) shows that both the component of the chaotic motion and the component of the stochastic motion exist in the pressure fluctuation in the slugging fluidized bed and in the circulating fluidized bed.
The theoretical analysis shows that periodic forcing onlyexcites the polar motion with the corresponding period, and stochastic motion is oneexciting source with the best probability for the Chandler Wobble.
Nonlinear effects of the gradient inhomogeneity of the magnetic field on the stochastic motion of charged particles due to an electrostatic wave propagated arbitarily relative to the m-agnetic field are considered in this paper.
Simulating random movement of sea wave in the wave basin and making researchs into the action of sea wave on coastal and offshore structures could provide the reliable basis for engineering design and scientific experimentation.
This paper not only discusses the application of Brownian Motion Theory in the field of natural science and social science on the basis of solving differential equations of random movement of Brownian Particles but also explains its wide suitability of the phenomena of the random fluctuations.
The first process is convection forced by tidal current field. The second process is the turbulent diffusion analogued by random movement. The third process is the sediment and resuspension process of particles.
The simulation test results indicate that it is convenient to establish the model of the target movement,especially the random movement,which cannot be described by the mathematical equation. Thus the flight simulation can easily be implemented.
Based on the hypothesis that the Chandler wobble is excited by stochastic motions, a nonlinearly stochastic model for study of the Chandler wobble is proposed, which is composed of a Heaviside's step function with stochasticity and a Eulerian centred differential scheme for linear oscillator with drag.
According to the statistical theory of Brownian motions,it is issued that turbulences in the unstable fluid motions are caused by the molecule thermodynamic motions and produce the stochastic motions in various macroscales,which are the nature of the atmospheric motions.
A number of recent experimental investigations of nonideal plasmas containing macroparticles have revealed an anomalous increase in that part of the kinetic energy of these macroparticles that corresponds to their random motion.
It is shown that there exists a certain region in which a particle performs a stationary random motion without appreciable drift.
Volume rechanneling takes place under the conditions of random motion.
The transition from heating to cooling is explained by the change in the ratio of the average charge of channeled ions to the average charge of ions with random motion in the crystal.
The random motion of silica particles was more severely restricted when the particle was larger and the network mesh size was smaller at higher CTAB concentrations.
The distribution of marked moths in lights and pheromone traps is consistent with a predominantly downwind dispersal close to the ground during the early part of the night and more random movement later on.
In both families, of the fish which displayed a choice, the proportion of fish swimming towards the reef was significantly greater than 50%, as random movement would predict (64% of pomacentrids and 67% of apogonids swam towards the reef).
In high univalent frequency collections it is argued that the non-random dyad distribution seen at anaphase I is the result of non-random movement of some of the equatorial univalents away from the equatorial region during anaphase I.
Chemotactic and random movement of human newborn monocytes
We derive a stochastic differential equation which describes the random movement of the phase separation point.
