Chemical reaction effects on hydromagnetic flow of a radiating and dissipative fluid past a tilted stretching sheet

Peter F. FASOGBON*, Rasheed A ADETONA

This paper probes into the chemical reaction e ects on steadyhydromagnetic ow of an incompressible viscous electricallyconducting, radiating and dissipative uid past a tilted stretchingsheet in the presence of heat source. The governing boundarylayer equations are first transformed into a non-dimensional formusing suitable similarity variables and the resulting system ofordinary di erential equati...

Application of Variational Iteration Method to Linear and Non-Linear Stiff Differential Equations

M. O. Olayiwola*

In this paper, the variational iteration method (VIM) is usedto solve linear, non-linear and system of sti di erentialequations numerically. The numerical solutions obtained isin good agreement with the exact solutions of problems un-der investigations. The method is a promising tool for thesolution of stiff differential equations for the three systems.

Laplace Homotopy Perturbation Method for Solving Fourth Order Parabolic Partial Differential Equations with Variable Coefficients

O. O. Olubanwo*, O .S. Odetunde

In this paper, we present a reliable combination of the Laplace transform and Homotopy perturbation method to solve one-dimensional fourth-order parabolic linear partial differential equations with variable coefficients. Some cases of one-dimensional fourth-order parabolic linear partial differential equations are considered to illustrate the ability and reliability of the mixture of the Laplace t...

Result on the Existence and Uniqueness of the Fixed Point with Mann Iteration in a Complete G-Metric Space

A. A. Idowu*, B. Y. Aiyetan, K. Rauf, L. Aminu

In this research, we prove the existence and uniqueness ofthe mixed point in a complete G-metric space using severalgeneralised contractive conditions formulated in G-metricsettings, taking Mann-iteration as our iterative procedure. Our results improve and extend some well-knownresults in the literature. We have utilized these conceptsto deduce that Mann iterative procedure is G-convergent,G-Cauch...

An Operator for Obtaining Nth Order Derivative of a Function Depending on Seven Independent Variables

O. O. Enoch*, F. J. Adeyeye, A. O. Ilesanmi, S. O. Adejuwon

Leibnitz's theorem is used in the product rule to generatea series method for computing the nthorder derivative ofa function that depends on seven Independent variables.The new series method does not require the knowledge ofthe preceding derivative before obtaining the succeedingones. A generalization of the method is also presented.

A Class of Implicit Five Step Hybrid Method for Solving First Order Initial Value Problem

L. Idris*, Y. A. Yahaya, U. Mohammed

In this paper, a self-starting five step continuous block hybridformulae (CBHF) with one Off-step point is developed using col-location and interpolation procedures. The CBHF is then used toproduce multiple numerical integrators that are of uniform orderand are assembled in to a single block matrix equation. Theseequations are simultaneously applied to provide the approximatesolution for the ordin...

Unsteady Mhd Oscillatory Flow Through A Porous Channel Saturated With Porous Medium

S. A. Onitilo*

In this paper, we investigate the effect of suction/injection on the unsteady oscillatory flow through a vertical channel with non-uniform wall temperature. The fluid is subjected to a transverse magnetic field, and the velocity slip at the lower plate is taken into consideration. Exact solutions of the dimensionless equations governing the fluid flow are obtained, and the effects of the flow para...

Modeling The Fluid Flow for Seepage Problem: A Crank-Nicolson Approach

A. A. Hassan*, I. O. Abiala, J. S. Aroloye

The two-dimensional Laplace equation (which models the fluid flow of the seepage problem) was solved by a finite difference method, which is the Crank-Nicolson Method (CNM) subject to some boundary and initial conditions. We compared the numerical results of CNM to the Alternating Direction Explicit Finite Difference Scheme (ADES). First, we derived the finite differential form of the implicit, ex...

A Markov Chain Prediction Model on a Major Pair in the Currency Market

Emmanuel O. Oduselu-Hassan*

The Markov chain prediction model is a type of stochastic model and very useful in predicting prices of stocks and exchange rates with outcomes that appear to be random in nature due to many factors that influence the price movement. The uncertainty in the price of the stocks and exchange rates arose. from the many factors, which include the economy of the region, financial and economic news of ot...
