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...

A Mathematical Model on Marburg Virus Disease

Ayinla Ally Yeketi^*, Ayinla Abdulquadri Yeketi

This research discusses the management of Marburg virus disease (MVD) using a mathematical model. The formulated model consists of five (5) mutually exclusive compartments. The local and global stability of the DFE of the formulated model is established. Subsequently, it is shown that the e ective management of the disease depends greatly on the incubation period and exposure to the infection. The...

New Approximate Method for Systems of Non-linear Volterra Integro-Differential Equations

M. D. Aloko^*, D. A. Johnson, J. A. Osilagun

In this paper, we present a new iterative scheme for approximating nonlinear systems of Volterra-integro-differential equations. The algorithm relies on the principles of the Variational Iteration Method (VIM). The modified method provides successive approximations by variational theory, decomposition techniques, and correction functional on Lagrange’s multiplier. In comparing with numerous result...

A New Numerical Algorithm for the Solution of General Second Order Ordinary Differential Equations

Lawrence Osa Adoghe^*

This paper contains the formulation of an algorithm for solving general second order initial value problems of ordinary differential equations. This method is basically a continuous linear multistep (clmm) block method obtained from the collocation and interpo lation of a functional as basis function. Its implementation was on the evaluation of the main method and two additional methods of the blo...

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...

Thermal Diffusion and Diffusion-Thermo Effects on Ohmic Heating with Mhd Free Convective Flow Past a Vertical Porous Plate in the Presence of Viscous Dissipation

H. Usman^*, I. J. Uwanta, Z. Sanusi

The MHD laminar boundary layer ow with heat and mass transfer of an electrically conducting viscous uid in a porous medium with ohmic heating and viscous dissipation e ects is studied numerically. The governing systems of nonlinear partial di erential equations of the ow, heat and mass transfer processes are solved using implicit nite di erence scheme of Crank-Nicolson type. The numerical solution...

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...

On the Stability Analysis of a Sixth-Stage Fifth- Order Runge-Kutta Method for Solving Initial Value Problems in Ordinary Differential Equations

G. U. Agbeboh, B. C. Ononogbo^*, M. E. Ehiemua

This article investigates the stability of a sixth-stage, fifthorder Runge-kutta method which had already been derived in our previous results. The method is subjected to the test equation given as y 0 = λy, where a complex constant is λ, and the resulting expansion and algebraic manipulations were done with the help of Maple-18 and Matlab package, to ease the simplification of the computation. Th...

Fixed Point Theorems with Rational Expressions over a Closed Subset of Hilbert Spaces

S. A. Aniki^*, E. E. Aribike, M. Raji, F. Adegboye, K. Rauf

In this paper, we prove the existence and uniqueness of a fixed point for a continuous self- mapping over a closed subset of Hilbert spaces satisfying nonlinear rational contractive-type condition. This result is extended and generalized for some positive integer powers of continuous self-mappings in Hilbert spaces.
