Cluster Analysis on Locally Asymptotically Self-Similar Processes with Known Number of Clusters

open access: yesFractal and Fractional, 2022
We conduct cluster analysis of a class of locally asymptotically self-similar stochastic processes with finite covariance structures, which includes Brownian motion, fractional Brownian motion, and multifractional Brownian motion as paradigmatic examples.

Confidence bands for Brownian motion and applications to Monte Carlo simulation [PDF]

open access: yes, 2006
Minimal area regions are constructed for Brownian paths and perturbed Brownian paths. While the theoretical optimal region cannot be obtained in closed form, we provide practical confidence regions based on numerical approximations and local time ...

Operator Fractional Brownian Motion and Martingale Differences

open access: yesAbstract and Applied Analysis, 2014
It is well known that martingale difference sequences are very useful in applications and theory. On the other hand, the operator fractional Brownian motion as an extension of the well-known fractional Brownian motion also plays an important role in both

The rapid points of a complex oscillation [PDF]

open access: yesLogical Methods in Computer Science, 2012
By considering a counting-type argument on Brownian sample paths, we prove a result similar to that of Orey and Taylor on the exact Hausdorff dimension of the rapid points of Brownian motion.

CFD simulations on natural convection heat transfer of alumina-water nanofluid with Brownian motion effect in a 3-D enclosure [PDF]

open access: yesJournal of Particle Science and Technology, 2016
The CFD simulation has been undertaken concerning natural convection heat transfer of a nanofluid in vertical square enclosure, whose dimension, width height length (mm), is 40 40 90, respectively.

Thermo diffusion and diffusion thermo impacts on bioconvection Walter-B nanomaterial involving gyrotactic microorganisms

open access: yesAlexandria Engineering Journal, 2021
Here magnetohydrodynamic (MHD) bioconvection Walter-B nanofluid flow due to stretched sheet is considered. Significance of motile gyrotactic microorganisms and melting phenomena are scrutinized.

Generalized fractional Brownian motion

open access: yesModern Stochastics: Theory and Applications, 2017
We introduce a new Gaussian process, a generalization of both fractional and subfractional Brownian motions, which could serve as a good model for a larger class of natural phenomena.

Dynamics of Active Brownian Particles in Plasma

open access: yesMolecules, 2021
Experimental data on the active Brownian motion of single particles in the RF (radio-frequency) discharge plasma under the influence of thermophoretic force, induced by laser radiation, depending on the material and type of surface of the particle, are ...

Superstatistical Brownian Motion [PDF]

open access: yesProgress of Theoretical Physics Supplement, 2006
As a main example for the superstatistics approach, we study a Brownian particle moving in a d-dimensional inhomogeneous environment with macroscopic temperature fluctuations. We discuss the average occupation time of the particle in spatial cells with a given temperature.
