This paper aims at some representation of unified Voigt functions which play a rather important role in several diverse fields of physics such as astrophysical spectroscopy and the theory of neutron reactions. We derive ...

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. ...

The set of systems of differential equations that are in normal form with respect to a particular linear part has the structure of a module of equivariants, and is best described by giving a Stanley decomposition of that ...

An explicit finite-difference method is employed to study the MHD free convection heat generating fluid past an impulsively started vertical infinite plate when a strong magnetic field is applied perpendicular to the plate. ...

An asymptotic unfolding of a dynamical system near a rest point is a system with additional parameters, such that every one-parameter deformation of the original system can be embedded in the unfolding preserving all ...
