Adaptive Robust Profile Analysis of a Longitudinal Data

Gabriel Asare Okyere, Silverius Kwasi Bruku, Richard Tawiah & Gilbert Biney · Journal of Advances in Mathematics and Computer Science · 2018

This paper uses nine winsorized scores in the adaptive test of Hogg, Fisher and Randles and deals with its extension to hypothesis testing in profile analysis of a balanced longitudinal data. Simulation studies are conducted to evaluate the efficiency of the adaptive test procedu...

Two-Step Hybrid Block Method for Solving First Order Ordinary Differential Equations Using Power Series Approach

G. Ajileye, S. A. Amoo & O. D. Ogwumu · Journal of Advances in Mathematics and Computer Science · 2018

In this paper, we consider the derivation of hybrid block method for the solution of general first order Initial Value Problem (IVP) in Ordinary Differential Equation. We adopted the method of Collocation and Interpolation using power series approximation to generate the continuo...

Influence of Chemical Reaction, Viscous Dissipation and Joule Heating on MHD Maxwell Fluid Flow with Velocity and Thermal Slip over a Stretching Sheet

I. G. Baoku · Journal of Advances in Mathematics and Computer Science · 2018

A numerical integration scheme involving a fourth-fifth Runge-Kutta-Fehlberg method (RKF45) with shooting technique is employed to investigate a steady laminar incompressible forced convective flow of an upper-convected Maxwell fluid which is subjected to a transversely uniform m...

Fuzzy Risk Measure for Operational Risk

Assem Tharwat, Ramadan A. ZeinEldin, Hamiden Abd El-Wahed Khalifa & Ahmed M. Saleim · Journal of Advances in Mathematics and Computer Science · 2018

Operational risk is one of the most hazardous types of risk banks face. Banks must take caution and reserve capital to meet these risks. Value at Risk (VaR) and Expected Shortfall (ES) used to measure operational risk and estimate the required capital to meet it. Value at Risk is...

Modelling Vaccination and Treatment of Childhood Pneumonia and Their Implications

Cyrus Gitonga Ngari · Journal of Advances in Mathematics and Computer Science · 2018

This paper presents a deterministic model for pneumonia transmission and uses the model to assess the potential impact of the vaccination, treatment and efficacy of vaccination drugs in lowering the public health impact of the pneumonia disease. The model is based on the Suscepti...

Modelling HIV In-vivo Cellular Dynamics in the Presence of Antiretroviral Therapy

A. K. Omoyeni & T. T. Yusuf · Journal of Advances in Mathematics and Computer Science · 2018

A treatment strategy for the total eradication of human immunodeficiency virus (HIV) in infected individuals is presently not feasible. However, the adoption of highly-active antiretroviral therapy (HAART) has been effective in managing HIV/AIDS infected patients in recent times....
