On a Hybrid Clayton-Gumbel and Gumbel-Frank Bivariate Copulas with Application to Stock Indices

Maxwell Akwasi Boateng, Akoto Yaw Omari-Sasu, Nana Kena Frempong & Richard Kodzo Avuglah · Journal of Advances in Mathematics and Computer Science · 2018

The study proposes two convex convolution based bivariate Archimedean copulas with their joint distribution functions and conditional distribution functions. Several simulations were performed using sample sizes 100,1000, 10000 and 1000000 for combinations of distributions: Gamma...

A Mathematical Model for Mycolactone Toxin Reaction and Diffusion in Cell Cytoplasm

Peter Romeo Nyarko, Isaac Kwame Dontwi & Nana Kena Frempong · Journal of Advances in Mathematics and Computer Science · 2018

The study of mechanisms and transport of proteins inside cells provide understanding of the dynamics of biological systems and give clues to biological effect of drugs on our system. Reaction-diffusion mechanisms inside cells control various cell functions from adhesion, haptotax...

Fractional Order SIR Model with Constant Population

Eric Okyere, Francis Tabi Oduro, Samuel Kwame Amponsah, Isaac Kwame Dontwi & Nana Kena Frempong · Journal of Advances in Mathematics and Computer Science · 2016

The main objective of this paper is to formulate an epidemiological model using fractional order derivatives which has an advantage over the classical integer order models due to its memory effect property. Our mathematical formulation of the non-integer order initial value probl...
