Mathematical Study of In-host Dynamics of Hepatitis B Virus in Absence of Immunity System

Jannatun Nayeem & Chandra N. Podder · Journal of Advances in Mathematics and Computer Science · 2016

We develop a mathematical model to understand the dynamics of HBV-in host infection of individuals in vivo. The model incorporates the uninfected host cells, short lived infected cells, chronically infected cells, free virus particles, humoral immune response of HBV specific anti...

Comparison of Least Squares Method and Bayesian with Multivariate Normal Prior in Estimating Multiple Regression Parameters

Felix O. Mettle, Louis Asiedu, Enoch N. B. Quaye & Abeku A. Asare-Kumi · Journal of Advances in Mathematics and Computer Science · 2016

Based on an assumption of multivariate normal priors for parameters of multivariate regression model, this study outlines an algorithm for application of traditional Bayesian method to estimate regression parameters. From a given set of data, a Jackknife sample of least squares r...

A Numerical Method Based Boundary Integral Equation to Solve Multiphase Moving Boundary Problems

S. G. Ahmed, M. Saif AlDien & M. Y. Youssef · Journal of Advances in Mathematics and Computer Science · 2016

The present paper deals with moving boundary problems by fixing the moving boundary by an assumption of the form is assumed power and ς is an unknown. An iterative algorithm is then developed within the main algorithm to solve the phases that appear throughout the m whole process...

An Information-Theoretic Alternative to the Cronbach's Alpha Coecient of Item Reliability

E. Fokoué & N. Gündüz · Journal of Advances in Mathematics and Computer Science · 2016

We propose an information-theoretic alternative to the popular Cronbach alpha coefficient of item reliability. Particularly suitable for contexts in which instruments are scored on a strictly nonnumeric and non ordinal scale, our proposed index is based on functions of the entrop...

Oscillatory Blood Flow in Convergent and Divergent Channels, Part 1: Effects of Pulse Amplitude and Local Constriction Height

W. I. A. Okuyade & T. M. Abbey · Journal of Advances in Mathematics and Computer Science · 2016

Oscillatory blood flow in convergent and divergent channels is investigated. The problem which involves a set of non-linear differential equations is handled analytically using the method of regular perturbation series solutions. Solutions are obtained for the velocities, pressur...

Oscillatory Blood Flow in Convergent and Divergent Channels, Part 2: Effects of Reynolds Number

W. I. A. Okuyade & T. M. Abbey · Journal of Advances in Mathematics and Computer Science · 2016

This paper studies the effects of Reynolds number on the oscillating flow in convergent and divergent channels. The nonlinear equations governing the flow are solved analytically by the method of perturbation series solutions. Expressions for the velocities and wall shear stress...
