Bijections for classes of labelled trees
(University of Isfahan, 2024-01-09)Trees are acyclic connected graphs. Plane trees, d-ary trees, binary trees, non crossing trees and their generalizations, which are families of trees, have been enumerated by many authors using various statistics. These ... -
Bijections of k-plane trees
(Open journal of discrete Applied Mathematics, 2022)A k-plane tree is a tree drawn in the plane such that the vertices are labeled by integers in the set {1, 2, . . . , k}, the children of all vertices are ordered, and if (i, j) is an edge in the tree, where i and j are ... -
Bijections of plane Husimi graphs and certain combinatorial structures
(EU Academic Publishers, 2023-10-19)Plane Husimi graphs are combinatorial structures obtained when we replace edges in plane trees with complete graphs such that the resultant structures are connected and cycle free. The formula that counts these structures ... -

BUILDING STRENGTH FROM COMPROMISE; A CASE STUDY OF FIVE YEAR COLLABORATION BETWEEN THE STATISTICAL SERVICES CENTRE OF THE UNIVERSITY OF READING, UK AND MASENO UNIVERSITY, KENYA
(ICOTS, 2014)Statistics teaching and practice at Maseno University has benefited immensely from its collaboration with the Statistical Services Centre (SSC) at the University of Reading. The SSC, a self-sustaining entity providing ... -

Cesáro-like operators on the Hardy and Bergman spaces of the half plane
(Springer International Publishing, 2016-01-01)We construct integral operators associated with strongly continuous groups of invertible isometries on the Hardy spaces and the weighted Bergman spaces of the upper half plane. Specifically, we obtain the spectrum and point ... -
Combinatorics of oriented trees and tree-like structures
(Stellenbosch University, 2015)In this thesis, a number of combinatorial objects are enumerated. Du and Yin as well as Shin and Zeng (by a different approach) proved an elegant formula for the number of labelled trees with respect to a given ... -

Comparative Analysis of Spectral Theory of Second Order Difference and Differential Operators with Unbounded Odd Coefficient
(KYUNGPOOK, 2020)We show that selfadjoint operator extensions of minimal second order differ ence operators have only discrete spectrum when the odd order coefficient is unbounded but grows or decays according to specific conditions. ... -
Consistency Inference Property of QIC in Selecting the True Working Correlation Structure for Generalized Estimating Equations
(Science Publishing Group, 2019-06-29)The generalized estimating equations (GEE) is one of the statistical approaches for the analysis of longitudinal data with correlated response. A working correlation structure for the repeated measures of the outcome ... -

A cost - benefit analysis of substituting bamboo for tobacco: a case study of smallholder tobacco farmers in south Nyanza, Kenya
(Science Journal Publication, 2012)This study examined the economic and financial benefits and costs of farming bamboo as a crop substitute of tobacco in four (4) districts in South Nyanza, Kenya. The World Health Organization Framework Convention on ... -
Deficiency indices and spectrum of fourth order difference equations with unbounded coefficients
(WILEY‐VCH Verlag, 2013-03)Using subspace theory together with appropriate smoothness and decay conditions, we calculated the deficiency indices and absolutely continuous spectrum of fourth order difference equations with unbounded coefficients. In ... -
Effects of inclination angle and free convection on velocity profile for a steady 2-dimensional magnetohydrodynamic fluid flow in an inclined cylindrical pipe
(European Journal of Engineering and Technology Research, 2021)Effects of inclination and free convection on velocity profile for magnetohydrodynamic (MHD) fluid flow in an inclined cylindrical pipe has been investigated. The governing partial differential equations are the equations ... -
Effects of Structural Viscoelasticity in Non-Divergence free Deformable Porous Media with Incompressible Constituents
(Global Journal of Pure and Applied Mathematics, 2018)In this paper, we investigate the importance of structural viscoelasticity in the mechanical response of deformable porous media with incompressible constituents under sudden changes in the external applied quasi-static ... -
Empowered schools embrace the competency based curriculum: sharing the Kenya connect empowered school model in Machakos county
(Journal of Education and Practices, 2021)Rural public schools face many challenges and are severely under-resourced. Students are eager to learn and parents see schools as a means for upward mobility for their children. However, public schools struggle due to ... -
Enumeration of plane and d-ary tree-like structures
(Annals of Mathematics and Computer Science, 2023-08-26)Trees are generalized using various approaches such as considering tree-like structures. Some of the tree-like structures are Husimi graphs, cacti and oriented cacti. These graphs have been enumerated according to number ... -
Envisioning Change in the Statistics-Education Climate.
