Common Fixed Point Theorems for Five Self Mappings in a Complete Metric Space

I. A. Sani*, K. Rauf

In this research work, we use five different operators P, Q, R, T, and B, to show that there exists a common fixed point among the five operators and prove the uniqueness. Furthermore, we establish that the pairs (R,B),(R,Q),(R,T) and (R,P) are weakly compatible (that is they commute). The result extend and improve the work of Latpate and Dolhare (2017).

MOBILE DIGITAL CASH PAYMENT FOR MOBILE PHONE USERS

Usman F*, Olabiyisi S. O, Emuoyibofarhe O. J

As mobile communications become increasingly sophisticated and ubiquitous, the use of portable devices aims to exploit the increasing processing power of these consumer devices. This paper proposes a new computing model that tries to provide user mobility service to all applications through a system-level solution. It present the design and implementation of a model for mobile computing called Web...

Crank-Nicolson Galerkin Error Estimates for Linear Stochastic Wave Equation driven by Space-Time White Noise

Ignatius N. NJOSEH*

We considered the linear stochastic wave equation driven by space-time white noise. The Galerkin finite element method was used to derive the approximate solution. For the time discretization, we applied the Crank-Nicolson finite di erence approximation scheme and the error estimates were proved both in the L2 and maximum norms.

Hydromagnetic radiative flow past a vertical oscillating plate with chemical reaction in presence of heat source

Peter F. FASOGBON*, Y. O. Tijani

In the present article, we study time-varying hydromagnetic chemically reacting free convective flow of a viscous, incom pressible radiating fluid past an infinite oscillating vertical plate with variable surface conditions subject to transverse magnetic field in the presence of temperature dependent heat source. Soret and Dufour effects are taken into consideration. The radiative heat flux is sim...

Third Derivative Block Hybrid Obrechkoff Methods

B. I. Akinnukawe*, O. A. Akinfenwa, S. A. Okunuga

This paper presents a family of Third Derivative Block Hybrid Obrechkoff Methods of Adams-type for solving stiff Initial Value Problems (IVPs). Multistep collocation techniques, with power series as basis function, are employed for the derivation of the continuous form of the hybrid methods. The continuous Hybrid Obrechkoff Methods are used to generate several implicit Hybrid Integrators that are ...

On the Performance Assessment of Mean Methods in Estimating Process Capability for Skewed Distributions

J. O. Braimah*, S. O. Elakhe, N. Edike

This study compares the performances of Gini Mean, Clementsand Box-Cox transformation methods for estimating processcapability Indices when the distribution of the process data is(skewed) non-normal. The use of process performance index(PPI) is implored for process capability analysis (PCA) usingWeibull distribution. Data was simulated using R software witha decision interval (target point) of 1.0...

DERIVATION AND ANALYSIS OF BLOCK IMPLICIT HYBRID BACKWARD DIFFERENTIATION FORMULAE FOR STIFF PROBLEMS

MUHAMMAD, R.*, Y. A. Yahaya, L. Idris

The Hybrid Backward Differentiation Formula (HBDF) for the case k = 3 was reformulated into continuous form using the idea of multistep collocation. The continuous form wasevaluated at some grid and of grid points, which gave rise to discrete schemes employed as block methods for direct solution of the first-order ordinary differential equation y0 = f(x; y). Therequirement of a starting value and ...

Numerical Approximation of Fractional Relaxation-Oscillation Equation by Aboodh Transform Method

O. O. Olubanwo*, A. T. Talabi, O. A. Dehinsilu, O .S. Odetunde

In this paper, we present the approximate solutions of fractional relaxation-oscillation equations by using Aboodh Transform Method (ATM). Some examples are considered to illustrate the capability and reliability of the method. The solutions obtained are presented in the form of rapidly convergent series with easily computable terms. The results obtained by ATM are compared with the exact solution...
