An unconditionally stable nonstandard finite difference method applied to a mathematical model of HIV infection
(De Gruyter Open, 2013)
We formulate and analyze an unconditionally stable nonstandard finite difference method for a mathematical model of HIV
transmission dynamics. The dynamics of this model are studied using the qualitative theory of dynamical ...
The fibre of a pinch map in a model category
(Springer Verlag, 2013)
In the category of pointed topological spaces, let F be the homotopy fibre of the
pinching map X ∪ CA → X ∪ CA/ X from the mapping cone on a cofibration A → X
onto the suspension of A. Gray (Proc Lond Math Soc (3) ...
A model for control of HIV/AIDS with parental care
(World Scientific Publishing, 2013)
In this study we investigate the HIV/AIDS epidemic in a population which experiences
a significant flow of immigrants. We derive and analyze a mathematical model that
describes the dynamics of HIV infection among the ...
An optimal portfolio and capital management strategy for basel III compliant commercial banks
(Hindawi Publishing Corporation, 2014)
We model a Basel III compliant commercial bank that operates in a financial market consisting of a treasury security, a marketable security, and a loan and we regard the interest rate in the market as being stochastic. We ...
Fifth order two-stage explicit Runge-Kutta-Nystrom method for the direct integration of second order ordinary differential equations
(Academic Journals, 2012)
In this paper a direct integration of second-order Ordinary Differential Equations (ODEs) of the form using the Explicit Runge-Kutta-Nystrom method with higher derivatives is presented. Various numerical schemes are derived ...
Numerical treatment of Kap's equation using a class of fourth order method
(Academic Journals, 2011)
Kap's equation is a stiff initial value problem. This paper deals with the treatment of Kap's equation using a class of 4th order explicit Runge-Kutta method. Numerical computation was carried out using Microsoft Visual ...
Multiplication of Crowns
(Instituto de Matematica de Bahia Blanca (INMABB-CONICET), 2013)
It is known that the only nite topological spaces that are H-spaces are the discrete spaces. For a nite poset which is weakly equivalent to an H-space, a generalized multiplication may be found after suitable ...
An assessment of the age reporting in Tanzania population census
(Academic Research Publishing, 2012)
The objective of this paper is to provide data users with a worldwide assessment of the age reporting in the Tanzania Population Census 2012 data. Many demographic and socio-economic data are age-sex attributed. However, ...
Neighbourhood operators: additivity, idempotency and convergence
(Springerlink, 2019)
We define and discuss the notions of additivity and idempotency for neighbourhood and interior operators. We then propose an order-theoretic description of the notion of convergence that was introduced by D. Holgate and ...
Automorphism groups of graph covers and uniform subset graphs
(Taylor and Francis Group, 2018)
Hofmeister considered the automorphism groups of antipodal graphs through the exploration of graph covers. In this note weextend the exploration of automorphism groups of distance preserving graph covers. We apply the ...
