The Boubaker Polynomials

Expansion

Scheme BPES has been used by several applied physics and engineering studies. Agida et al. used this protocol for establishing an analytical method for solving Love integral equation in the case of a

rational

kernel.

O. B. Awojoyogbe et al. took profit from the similarities between the hemodynamic flow system inside some organic tissues and the BPES definition system, in order to express the tissue response to magnetic fields excitation.
Kumar combined the Boubaker Polynomials Expansion Scheme (BPES) analyses and array analyses for determining the normalized field created conjointly by two

similar

circular coaxial conducting disks

separated

by a pre-fixed

distance

. On an other hand, J. Ghanouchi et al. used the BPES to discuss the intriguing

paradox

of establishment of non-Gaussian isothermal generative lines beneath a plate surface targeted by a Gaussian beam.

The works carried out by S. Slama et al. proposed solutions to the heat transfer problem inside different welding and annealing systems. These works used the BPES as a guide to solve heat

discrete

conservation equations during cooling phases, and yielded

consistent

cooling velocities profile. T. Ghrib et al. used the BPES in order to establish a

first order

correlation between the Vickers microhardness and the thermal diffusivity of treated steel alloys.

In the last years, S. Lazzez et al. and D. H. Zhang et al. investigated semiconductor micro layers physical properties using the BPES. More recently, A. Yildirim et al. proposed analytical solutions to the KleinÃÆÃÂ¢Gordon equation in a pulsed

stationary

regime using modified variational iteration method (MVIM) and BPES. GengÃÆÃÂ¢s standard

second-order

boundary value problem (BVP) was also investigated by D.H. Zang et al. using the BPES.

In a different filed like animal biology and medical sciences, Dubey et al. proposed, in a study commented and corrected by Milgram, an analytical method for the identification of predatorÃÆÃÂ¢prey populations time-dependent evolution in a Lotka-Volterra predatorÃÆÃÂ¢prey model which took into account the

concept

of accelerated-predator-satiety, O. B. Awojoyogbe et al. proposed also a mathematical formulation for the NMR diffusion equation derived from the Bloch NMR flow in lower heart coronary artery. This formulation was totally based on the properties of the Boubaker polynomials expansion scheme BPES.
