Modelling and Optimal Control of Typhoid Fever Disease with Cost-Effective Strategies
(Hindawi Publishing Corporation, 2017)
We propose and analyze a compartmental nonlinear deterministic mathematical model for the typhoid fever outbreak and optimal control strategies in a community with varying population.The model is studied qualitatively ...
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 ...
Modelling childhood disease outbreak in a community with inflow of susceptible and vaccinated new-born
(Research India Publications, 2016)
This paper investigates the transmission dynamics of a Childhood disease outbreak in a community with direct inflow of susceptible and vaccinated new-born. Qualitative analysis of the SEIR nonlinear model is performed ...

Hydromagnetic Bioconvection of Nanofluid over a Permeable Vertical Plate due to Gyrotactic Microorganisms
In this paper, we investigate the bioconvection induced by the hydromagnetic flow of a novel type of a water based nanofluid containing nanoparticles and motile microorganisms past a permeable vertical moving surface. ...
Comparison of crisp and fuzzy classification trees using gini index impurity measure on simulated data
(European Scientific Institute, 2015-02-09)
Crisp classification trees have been used to model many situations such as disease classification. With the introduction of fuzzy theory, fuzzy classification trees are gaining popularity especially in data mining. ...
The role of quality adoptnion in growth and management of Small & Medium Enterprises In Kenya
In today’s business environment, small and medium enterprises (SMEs) cannot afford to ignore the strategic implications of quality for its competitive position. Research shows that most SMEs lose between 5%-15% of sales ...
Modelling Internally Displaced Persons’ (IDPs) Time to Resuming their Ancestral Homes after IDPs’ Camps in Northern Uganda Using Parametric Methods
In this paper the time that the Internally Displaced Persons (IDPs) took to return from IDPs Camps to their ancestral homes in Northern Uganda was modeled using parametric methods. A retrospective dataset was collected ...
Hydromagnetic Mixed Convection Flow of Nanofluid with Slip, Viscous Dissipation and Joule Heating Past an Inclined Plate
(American Scientific Publishers, 2017)
A numerical analysis is performed on the combined effects of Joule heating and viscous dissipation on a steady two-dimensional flow of an electrically conducting water-based nanofluid containing three different nanoparticles: ...
Properties of the symmetric groups Sn (n≤7) acting on unordered triples
(African Journal of Mathematics and Computer Science Research, 2012-08)
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 sub-degrees and the numbers ...
