Weak Convergence to Brownian Meander and Brownian Excursion

open access: yesAnnals of Probability, 1977
We show that (i) Brownian motion conditioned to be positive is Brownian meander; (ii) tied-down Brownian meander is Brownian excursion; and (iii) Brownian bridge conditioned to be positive is Brownian excursion. Using these results we derive the distribution of the suprema of the meander and excursion.

A Relation between Brownian Bridge and Brownian Excursion

open access: yesAnnals of Probability, 1979
It is shown that Brownian excursion is equal in distribution to Brownian bridge with the origin placed at its absolute minimum. This explains why the maximum of Brownian excursion and the range of Brownian bridge have the same distribution, a fact which was discovered by Chung and Kennedy.

Numerical Solution of Vasicek Equation by Using Brownian Wavelets and Multiple Ito-Integral [PDF]

open access: yesControl and Optimization in Applied Mathematics, 2020
In this paper, we present a new approach to solving stochastic differential equations and the Vasicek equation by using Brownian wavelets and multiple Ito-integral.

A revised model for the effect of nanoparticle mass flux on the thermal instability of a nanofluid layer

open access: yesDemonstratio Mathematica, 2021
A revised model of the nanoparticle mass flux is introduced and used to study the thermal instability of the Rayleigh-Benard problem for a horizontal layer of nanofluid heated from below.

Brownian Refrigerator [PDF]

open access: yesPhysical Review Letters, 2006
Onsager symmetry implies that a Brownian motor, driven by a temperature gradient, will also perform a refrigerator function upon loading. We analytically calculate the corresponding heat flux for an exactly solvable microscopic model and compare it with molecular dynamics simulations.

The flashing Brownian ratchet and Parrondo’s paradox [PDF]

open access: yesRoyal Society Open Science, 2018
A Brownian ratchet is a one-dimensional diffusion process that drifts towards a minimum of a periodic asymmetric sawtooth potential. A flashing Brownian ratchet is a process that alternates between two regimes, a one-dimensional Brownian motion and a ...

ON THE QHASI CLASS AND ITS EXTENSION TO SOME GAUSSIAN SHEETS

open access: yesInternational Journal for Computational Civil and Structural Engineering, 2022
Introduced in 2018 the generalized bifractional Brownian motion is considered as an element of the quasi-helix with approximately stationary increment class of real centered Gaussian processes conditioning by parameters.

Compact Brownian surfaces I: Brownian disks [PDF]

open access: yesProbability Theory and Related Fields, 2017
We show that, under certain natural assumptions, large random plane bipartite maps with a boundary converge after rescaling to a one-parameter family ($\mathrm{BD}_L$, $0 < L < \infty$) of random metric spaces homeomorphic to the closed unit disk of $\mathbb{R}^2$, the space $\mathrm{BD}_L$ being called the Brownian disk of perimeter $L$ and unit
