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 ...

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 ...

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 ...

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. ...

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. ...

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 ...

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 ...

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: ...

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 ...
