APPLICATION OF HOMOTOPY PERTURBATION METHOD (HPM) FOR THE SOLUTION OF NANOFLUIDS OVER A POROUS STRETCHING SURFACE

U. Mohammed*, A. A. Mohammed, A. I. Ma’ali, E. O. Titiloye

In this study, by means of homotopy perturbation method (HPM) and sixth order Runge-Kutta method an approximate analytical and numerical solutions of the of viscous ag-water and Cu-water nanofluids over a porous stretching surface is obtained. Graphical results are presented to investigate the influence of the nanoparticles volume fraction parameter and suction/injection parameter on the velocity ...

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...

On The Strength of Agreement Between Students’ Initial and Final Academic Performances In Nigeria University System

A. W. Banjoko*, Yahya W. B., H. S. Abiodun, M. O. Adeleke, B. Afolayan, M. K. Garba, Olorede K. O., K. A. Dauda

This paper examines the strength of agreement between academic performances of students after their first and final years in the University. Academic performances of a total of 886 students that were admitted into various academic programs in the Faculty of Science, University of Ilorin, during the 2008/2009 academic session were followed-up to their year of graduation in 2012. Information on the ...

Mathematics Teaching as a Fundamental Tool for Self-Reliance and National Development

Khadijat Saka AMEEN*, Semiu Ayinla SALAWU, Saidat Morenike ADENIJI

Mathematics teaching is an interaction between the teacher and the learners that leads to acquisition of desirable mathematical knowledge, ideas and skill. These mathematical ideas, knowledge and skills form the basic essential tools for human and national independence. This paper therefore discusses the concept of self-reliance, the concept of National development, the concept of Mathematics teac...

Block Hybrid Method for Solution of Fourth Order Ordinary Differential Equations

O. A. Akinfenwa*, H. A. Ogunseye, S. A. Okunuga

In this paper a block hybrid method of order seven for the direct solution of fourth-order ordinary differential equations is presented. The derivation of the method uses interpolation and col-location procedures to obtain the main method and additional methods from the same continuous scheme. The continuous representation of the integrators permit us to differentiate and evaluate at both grid and...

Strengthened of Some Results on Fuzzy Soft Multiset Theory

H. M. Balami*, I. A. Onyeozili

In this paper, we present the definition of fuzzy soft multi set and its basic operations such as complement, union and intersection as introduced in 2012. We define the operations such as restricted intersection, restricted union, AND-product, OR-product, restricted difference and restricted symmetric difference. Basic algebraic properties of these operations are presented with relevant examples....

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...

A Mathematical Model of Cooperative Advertising and Subsidy Transfer Strategies

Peter E. Ezimadu*

This work uses game theory to consider cooperative advertising in a supply chain involving a manufacturer, a retailer, and a distributor. The manufacturer who is the channel leader plays aStackelberg game with the other channel members. While the distributor is the first follower (or second leader), the retailer is the second follower. The channel structure involves a situation where only the reta...
