CONSTRUCTION OF POLYNOMIAL BASIS AND ITS APPLICATION TO ORDINARY DIFFERENTIAL EQUATIONS

Aliu, T.^*, O. M. Bamigbola

The study identifies the versatility of basis functions in expansionary method by constructing basis functions of finite order, which satisfy some smoothness and differentiability conditions. Effort was intensified towards solving empirical problems via the finite element method.

ON SPECIAL CASES OF OPIAL'S AND HARDY'S INEQUALITIES

Anthonio Y. O^*, K. Rauf, Michael Oyelami Ajisope, Wahab Olalekan Taofeek

In this paper, we establish the relationship between Opial-type and Hardy-type integral inequalities which extend Anthonio and Rauf Opial-type inequalities for convex function.

Error Estimates of the Fully Discrete Solution of Linearized Stochastic Cahn-Hilliard Equation

Ignatius N. NJOSEH^*, H. I. OJARIKRE

We studied the finite element analysis of the linearized Stochastic Cahn-Hilliard equation. The Galerkin finite element method was used to discretize the given equation. Based on the finiteelements, the completely discrete approximation scheme was formulated by applying the backward Euler difference approximation in time. The completely discrete solution was interpreted.in terms of analytic semigr...

A Two Step Lo- Stable Second Derivative Hybrid Block Method for Solution of Still Initial Value Problems

OLUSHEYE AKINFENWA^*, ALI AHMED, OSUNKAYODE KABIR

We present a two step Lo-stable second derivative hybrid block method of order eight for the direct solution of still Initial Value Problems (IVPs). The main method and additionalmethods are obtained from the same continuous scheme derived using interpolation and collocation technique to form the block method. The stability properties of the block methodis discussed via a single matrix equation. T...

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.

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 ...

JUST-IN-TIME SCHEDULING PROBLEMS ON IDENTICAL PARALLEL MACHINES

M. O. Adamu^*, Abass O.

Problems involving Just-In-Time (JIT) scheduling provide an interesting and difficult challenge, which is addressed critically within this paper. This study considers the scheduling of parallelidentical machines to maximize the (weighted) number of on-time jobs. This problem is known to be NP-complete. Three problems were dealt with in this paper. Two greedy heuristics with time complexity O(n log...

A NOTE ON A CHARACTERIZATION OF LOCAL NULL SEQUENCE

SUNDAY OLUYEMI^*

We replace an arbitrary sequence of positive real numbers by a sequence of positive integers in a characterization of local null sequence, and consequently procure an example of a separated locally convex space in which convergence is Mackey.
