A natural occurrence of shift equivalence in a purely algebraic setting constitutes the subject matter of the following short exposition.
Radiation effects on natural convection MHD flow in a rotating vertical porous channel partially filled with a porous medium
Natural convection radiation permeability
2010/9/21
The unsteady natural convection MHD flow of a rotating viscous electrically conducting fluid in a vertical channel partially filled by a porous medium with high porosity in the presence of radiation e...
Comparing of the HAM with the HPM in finding the natural frequency of a nonlinear oscillating system
Frequency Nonlinear oscillation Series solutions
2010/9/13
In this article, we use an efficient analytical method called homotopy analysis method (HAM) to derive the frequency of a nonlinear oscillating system. Unlike the perturbation method, the HAM does not...
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...
Optimization of a photobioreactor biomass production using natural light
Optimal control Biological systems Modeling
2010/12/3
We address the question of optimization of the biomass long term productivity
in the framework of microalgal biomass production in photobioreactors under the influence
of day/night cycles.
In this article, we first state some relations about the number of partitions of a set under some particular conditions and then we give a new relation about the number of partitions of an n-set, i.e....
