Linear programming is the optimization of a linear function under constraints of linear equations or inequalities. Since much of the information in the real world is unknown, linear programming does not produce acceptable results due to the need for accurate information and data in many real-world decisions. The grey system is one of the most effic...

Non-linear dynamic problems are difficult to analyze since no general methods exist to deal with them, which namely depend on several factors such as the nature of the problem, the type of non-linearity or the type of solution to be sought. While some methods are used to study weak nonlinearities, others can more easily solve strong nonlinearities....

In this paper, the tracking control of a combination of two, three, four and five chaotic systems is achieved for the 2-D Duffing oscillator, 3-D Lorenz chaotic system and 4-D Lorenz–Stenflo chaotic system via recursive backstepping technique. The combination tracking control could find applications in situations where the total output of several c...

In this article, we propose a new numerical method based on fractal cubic spline for the numerical approximate solutions of linear and nonlinear singular two-point boundary-value problems. Error analysis of the proposed method is examined and it is shown that proposed method has second-order convergence. Numerical examples are provided to validate ...

In this work, we give new explicit solutions for the connection problems between generalized Lucas polynomial sequence and the two polynomials, namely third and fourth kinds of Chebyshev polynomials. The inversion connection formulae for these formulae are also provided. We show that all the derived expressions involve hypergeometric functions of t...

In the present paper, we use a Lie group of transformations to obtain a class of similarity solutions to a problem of a cylindrically symmetric shock wave propagating through one-dimensional, unsteady flow of a non-ideal gas. We assume that the gas has infinite electrical conductivity under the influence of axial component of the magnetic field, wi...

One of the fundamental problems in engineering processes is the efficient utilization of energy during convection in fluid flow. Studies show that entropy generation exists for all fluid transfer processes and entropy generation destroys useful energy. Furthermore, it has been discovered that some pertinent flow parameters might be chosen in order ...

A theoretical model for steady non-isothermal convective heat transfer in non-Newtonian magnetized micropolar gas flow from a non-linear stretching/contracting wall in the presence of strong magnetic field is presented, as a simulation of an MHD (magnetohydrodynamic) Hall energy generator. Subsonic flow is considered, and compressibility effects ne...

In this paper, we focused on the flow through an axisymmetric constricted artery of the pulmonary region to study the condition of stenosis. Theory of dust particles suspended in gas is applied on blood flow through the artery, where the “particles” represent “cells” suspended in plasma. The flow is governed by two dimensional Navier–Stokes’ equati...
