Non-homogeneous fractal hierarchical weighted networks. [PDF]

open access: yesPLoS ONE, 2015
A model of fractal hierarchical structures that share the property of non-homogeneous weighted networks is introduced. These networks can be completely and analytically characterized in terms of the involved parameters, i.e., the size of the original ...

Dense bidisperse suspensions under non-homogeneous shear [PDF]

open access: yesScientific Reports, 2023
We study the rheological behaviour of bidisperse suspensions in three dimensions under a non-uniform shear flow, made by the superimposition of a linear shear and a sinusoidal disturbance.

Non-Homogeneous Markov Set Systems [PDF]

open access: yesMathematics, 2021
A more realistic way to describe a model is the use of intervals which contain the required values of the parameters. In practice we estimate the parameters from a set of data and it is natural that they will be in confidence intervals.

Propagation of SH waves in an regular non homogeneous monoclinic crustal layer lying over a non-homogeneous semi-infinite medium

open access: yesInternational Journal of Applied Mechanics and Engineering, 2016
The present paper discusses the dispersion equation for SH waves in a non-homogeneous monoclinic layer over a semi infinite isotropic medium. The wave velocity equation has been obtained.

Analytical solutions of time-fractional models for homogeneous Gardner equation and non-homogeneous differential equations

open access: yesAin Shams Engineering Journal, 2014
In this paper, we obtain analytical solutions of homogeneous time-fractional Gardner equation and non-homogeneous time-fractional models (including Buck-master equation) using q-Homotopy Analysis Method (q-HAM).

On the Numerical Solution of 1D and 2D KdV Equations Using Variational Homotopy Perturbation and Finite Difference Methods

open access: yesMathematics, 2022
The KdV equation has special significance as it describes various physical phenomena. In this paper, we use two methods, namely, a variational homotopy perturbation method and a classical finite-difference method, to solve 1D and 2D KdV equations with ...

Preparation of some non-homogeneous cyclic compounds (pyrazolines and Isooxazolins) [PDF]

open access: yesمجلة التربية والعلم, 2012
In this paper number of some dichalcones (1-6) were prepared by reaction of one mole of acetone with two moles of benzaldehyde and benzaldehydes substituted (2-methoxy, 4-methoxy, 3,4-dimethoxy, 2-chloro and 4-nitro) in the presence of (10%) sodium ...
