On the Stability Analysis and Homotopy-Based Solution of three species Lotka-Volterra Model

E. A. Bakare*, S. Chakraverty

The Lotka-Volterra model is a description of the dynamic behaviour of a multispecies number of competitors and/or predator-prey interactions which have found usefulness in non-linear control and simultaneous chemical engineering and other engineering fields. In this paper, we present the stability analysis and homotopy based solution of three species Lotka-Volterramodel. The three species Lotka-Vo...

Assessing the impact of isolation on the transmission dynamics of Lassa Fever

Abubakar Tijjani*, Salisu Usaini, Muhammad Auwal Lawan

A non-linear deterministic mathematical model of Lassa fever with isolation of infected individuals is formulated and analysed. The model is shown to be well posed mathematically and epidemiologically. We obtained an important threshold parameter called the basic reproduction number R0. The presented model is shown to exhibits three equilibrium points each of which is proved to be globally asympto...

The Application of Runge-Kutta and Backward Differentiation Methods for Solving Transient Distribution in Markov Chain

S. O. Agboola*, N. I. Badmus

The computation of state probability distributions at an arbitrary point in time, which in the case of a discrete-time Markov chain means finding the distribution at some arbitrary time step n de noted π(n), a row vector whose ith component is the probability that the Markov chain is in state i at time step n, is the iterative solution methods for transient distribution in Markov chain. The soluti...

An Odd Order Numerical Integrator for Analyzing Environmental Models

O. O. Enoch*, C. O. Alakofa, E. J. Adeyeye, A. O. Ilesanmi, S. O. Adejuwon

In this work, we consider a class of formulae for the nu merical solution of Initial Value Problem (IVP) that is applicable in the study and analysis of Environmental pol lution Models. These classes of integrators are assumed to be an approximate reections of environmental problems.

On the use of Statistical Power in Examining Changes in Rainfall

Obisesan K. O*

The main objective of statistical analysis is to make inference. One way of doing this is through Hypothesis Testing and Post-hoc power analysis which can be applied to environmental phenomena such as rainfall. Rainfall is an important element in understanding the climatic condition of any environment. In this work, tests of hypothesis and post-hoc power analysis are carried out using monthly rain...

Development of an Order (k+3) Block-Hybrid Linear Multistep Method for the Direct Solution of General Second Order Initial Value Problems

A. A. Oyedeji*

Block hybrid linear multistep method was proposed to overcome the Dahlquist order barrier for linear multistep methods. We are interested in answering questions relating to the convergence, accuracy and effectiveness of block hybrid method when utilized to solve Initial Value Problems. In this research work, we presented an order (k+3) block hybrid method for the direct solution of initial value p...

Numerical Solution of a Generalized Fractional Burgers Diffusion Equation with Mamadu-Njoseh Polynomials

Emmanuel O. Oduselu-Hassan*, Ignatius N. Njoseh

In this paper, we consider the numerical solution of a generalized fractional Burgers diffusion equation (GFBE). A fractional variational iteration scheme coupled with Mamadu-Njoseh polynomials was developed to effectively solve the GFBE. MAPLE 18 software was used to carry out numerical simulations and approximations. Resulting numerical evidences show that the procedures converges rapidly to the...
