The Method of Variable False Tranelents for the Solution of Coupled Elliptic Equations
(Faculty of Science Kenyatta University, 2005)A method for the numerical solution of coupled, nonlinear elliptic, partial differential equation is described. The essential feature of the formulation is the use of different false transient factors in different flow ... 
Nonparametric Confidence Interval for a Shift Parameter for Cauchy distribution
(Ife Centre for Psychological Studies, 2005)In this article an application of a kernel based nonparametric approach in constructing a large sample nonparametric confidence interval for a shift parameter is considered. The method is illustrated using the Cauchy ... 
Asymptotic linear estimation of the quantile function of a locationscale family of distributions based on selected order statistics
(AFRICAN RESEARCH, 2005)Some general asymptotic methods of estimating the quantile function, Q(ξ), 0>ξ>1 of locationscale families of distributions based on a few selected order statistics are considered, with applications to some nonregular ... 
The Use of Mesh Generation Function for the Solution of Natural Convection Problems
(Faculty of Science Kenyatta University, 2005)A mesh generation procedure for the solution of coupled, nonlinear, partial differential equation is described. The essence of the procedure is the use of a grid generating function, which results in a strong refinement ... 
An improved theory of asymptotic unfoldings
(Elsevier, 20090801)An asymptotic unfolding of a dynamical system near a rest point is a system with additional parameters, such that every oneparameter deformation of the original system can be embedded in the unfolding preserving all ... 
Adomian Decomposition Method On Nonlinear Singular Cauchy Problem of EulerPoisson Darbuox equation
(Islamic Azad University, Rasht Branch, 2010)In this paper, we apply Picard’s Iteration Method followed by Adomian Decomposition Method to solve a nonlinear Singular Cauchy Problem of Euler Poisson Darboux Equation. The solution of the problem is much simplified ... 
Stanley decomposition for coupled takens–bogdanov systems
(Taylor & Francis, 201003)We use an algorithm based on the notion of transvectants from classical invariant theory in determining the form of Stanley decomposition of the ring of invariants for the coupled Takens–Bogdanov systems when the Stanley ... 
Hybrid approximation of solutions of nonlinear operator equations and application to equation of Hammersteintype
(Elsevier, 20110301)In this paper we study hybrid iterative scheme for finding a common element of set of solutions of generalized mixed equilibrium problem, set of common fixed points of finite family of weak relatively nonexpansive mapping ... 
Cycle Index of Internal Direct Product Groups
(International Mathematical Forum, 201112)If M and H are permutation groups with cycle indices ZM and ZH respectively, and if * is some binary operation on permutation groups, then a fundamental problem in enumerative combinatorics is the determination of a formula ... 
Singlestage Cluster Sampling with Binary Misclassification Errors
(JKUAT Press Ltd, 2012)Misclassification errors in single stage cluster sampling are considered where a binary variable is under study. The expectation and variance of the estimator is derived assuming correlated response errors. It is shown ...

On commutants and operator equations
(International Electronic Journal of Pure and Applied Mathematics, 2012)Let B(H) denote the algebra of bounded linear operators on a Hilbert Space H into itself. Given A,B ∈ B(H) define C(A,B) and R(A,B) : B(H) −→ B(H) by C(A,B)X = AX − XB and R(A,B)X = AXB − X. Our task in this note is to ... 
Limitations in the convectional isbn10 code.
(201202)The International Standard Book Number system (ISBN10) which was in operation until 2007 uniquely identified every book published internationally but was later replaced with the ISBN13. The code was had the ability to ... 
Relationship between Strategic Human Resource Management and Firm Performance of Kenya’s Corporate Organizations
(20120218)This paper examines the extent to which strategic human resource management influences firm performance from various critical perspectives. Rapid environmental changes, competition to provide innovative products and services, ... 
Properties of the symmetric groups Sn (n≤7) acting on unordered triples
(African Journal of Mathematics and Computer Science Research, 201208)In this paper, we investigated some properties associated with the action of symmetric group Sn (n≤7) acting on X(3). If Gx is the stabilizer of the lengths of the orbits of Gx on X are called subdegrees and the numbers ... 
Normal Form for Systems with Linear Part N3(n)
(Scientific Research, 201208)The concept of normal form is used to study the dynamics of nonlinear systems. In this work we describe the normal form for vector fields on R3n with linear nilpotent part made up of coupled n 3x3 Jordan blocks. We use ... 
Suborbits and Suborbital Graphs of the Symmetric Group n S acting on Ordered relement Subsets
(2013)The ranks and subdegrees of the symmetric group n S acting on [r] X , the set of all ordered relement subsets from X have been studied (See Rimberia [4]). In this paper, we examine some properties of suborbits and suborbital ... 
The – matrix completion problem for digraphs of matrices with less than four directed lines
(Innovative Journal, 2013)A real matrix is said to be –matrix if its principal minors are nonnegative and all its nondiagonal entries are nonpositive. In this project, we consider the –matrix completion problem. It is shown that any digraph with ... 
Combined effect of Buoyancy force and Navier slip on MHD flow of a nanofluid over a convectively heated vertical porous plate
(Scientific World, 2013)We examine the effect of magnetic field on boundary layer flow of an incompressible electrically conducting waterbased nanofluids past a convectively heated vertical porous plate with Navier slip boundary condition. A ...
