Homogenization driven by a fractional Brownian motion:the shear layer case
Homogenization driven fractional Brownian motion shear layer case
2015/7/14
We consider a passive scalar in a periodic shear flow perturbed by an additive fractional noise with the Hurst exponent H ∈ (0, 1). We establish a diffusive homogenization limit for the tracer when th...
Transport barrier for the radial diffusion due to the ExB drift motion of guiding centers in cylindrical confinement geometry
Transport barrier for the radial diffusion ExB drift motion cylindrical confinement geometry
2010/12/28
We consider the radial transport of test particles due to the E×B drift motion in the guiding center approximation. In a configuration where the magnetic field is constant and uniform in linear device...
Explicit approximate solution for finding the natural frequency of the motion of pendulum by using the HAM
Frequency Nonlinear oscillation Series solutions
2010/9/13
In this work, we use a powerful analytical method called homotopy analysis method (HAM) to derive the frequency of a nonlinear oscillating system. Unlike the perturbation method, the HAM does not requ...

Fractional Brownian Motion Fractional Calculus
2010/9/15
We study linear combinations of independent fractional Brownian motions and generalize several recent results from [10] and [17]. As a first new result we calculate explicitly the Hausdorff dimension ...

Fractional mixed fractional Brownian motion α-differentiability
2010/9/13
In this paper, we present some stochastic properties and characteristics of the fractional mixed fractional Brownian motion, and we study the α-differentiability of its sample paths.

2010/9/14
Analytical solutions to the equations of motion of inclined unsagged cables have been obtained by using the Lie group theory. The infinitesimal generators corresponding to the problem are calculated a...

Peristalsis power-law fluid trapping
2010/9/15
The flow separation (trapping) at the wall through peristaltic motion for non-Newtonian power-law fluid in uniform tube has been investigated under zero Reynolds number with long wavelength approximat...

Slow Motion the Maxwell Field
2010/11/1
We study the Abraham model for $N$ charges interacting with the Maxwell field. On the scale of the charge diameter, $R_{\phi}$, the charges are a distance $\eps^{-1}R_{\phi}$ apart and have a velocity...
