Analysis of a Steady Magnetohydrodynamic (MHD) Flow of a Convective Third Grade Fluid in a Constrained Geometry

Aiyesimi Y. M*, Jiya M., Olayiwola R. O., A. A. Wachin

This paper presents magnetohydrodynamic (MHD) flow of steady convective third-grade fluid in a constrained geometry. The non-linear governing equations were solved analytically.using homotopy perturbation method (HPM). The influences of dimensionless parameters on magnetohydrodynamic (MHD) flow of a convective third-grade fluid in a constrained geometrywere investigated. Simulation results reveale...

Modeling and Analytical Simulation of a Laminar Premixed Flame Impinging on a Normal Solid Surface

R. O. Olayiwola*

The two most relevant applications of laminar, compressible boundary layer theory are the flat-plate flow and stagnation-point flow. In this paper, an analytical method for studyingchemically reacting flow in laminar premixed flame of carbon monoxide/oxygen mixture in the region of the stagnation point in the presence of work due to compression and heat generateddue to viscous dissipation is prese...

Flow of an Incompressible MHD Third Grade Fluid Through a Cylindrical Pipe with Isothermal Wall and Joule Heating

Aiyesimi Y. M*, Okedayo G. T, Obi B. I

In this paper, we considered the flow of an incompressible MHD third grade fluid through a cylindrical pipe with isothermal wall and Joule heating. Axial pressure-gradient was assumed to have induced the motion. The governing equations of the flow field are solved using perturbation method. Results are presented.

Mathematical Recipe for Curbing Human Papillomavirus Transmission Dynamics

Abdulrahman S*, Popoola S. O, Yusuf I

A mathematical model for the transmission dynamics and control of Human Papillomavirus (HPV) was developed incorporating the impact of vaccination and condom usage. The effective reproduction number (Rc) was obtained and used to find the best recipe for curbing transmission of the disease. Using Nigerian demographic data, numerical simulations revealed that 20% HPV vaccination coverage of sexually...

CARDINALITY AND IDEMPOTENCY OF SIGNED ORDER-PRESERVING TRANSFORMATION SEMIGROUPS

M. M. Mogbonju*, S. O. Makanjuola, Adeniji A. O

Let SOn; SPOn and SIOn denotes the sets of signed full order - preserving, signed partial-order-preserving, and signed partial-one-one-order-preserving transformation semigroupsrespectively. Let be a transformation from Xn 􀀀! Z. This paper investigates and established the order and idempotency of the set of signed order-preserving transformation semigroups.

On a Hybrid Cryptography System for Data Using Advanced Encryption Scheme (AES) and Ron Rivest Shamir Adleman (RSA) Algorithms

A. O. Babatunde*, M. O. Mohammed

Nowadays, the use of information technology has taken over so many sectors. The survivals of many organizations are based on the information that is received or sent out. Due to the dependency on an unsecure communication network, some information that is confidential to the organization is revealed to an unauthorized user and this has necessitated the need for data security. This research work th...

A NEW NUMERICAL METHOD FOR THE SOLUTION OF INITIAL VALUE PROBLEMS

Abolarin O. E*, Akingbade S. W

A method of representing the exact solution to the initial value problem by an interpolating function is considered to generate a numerical method which enjoys the higher-order advantage over all the existing methods. The algorithm de veloped is coded using MATLAB programming application language towards its applicability. The effectiveness of the proposed method is tested and therefore found to c...
