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 ...
Self-similarity of human protein interaction networks: a novel strategy of distinguishing proteins
(2015)
The successful determination of reliable protein interaction networks (PINs) in several species in the
post-genomic era has hitherto facilitated the quest to understanding systems and structural properties of
such networks. ...
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, ...
A model of malaria population dynamics with migrants
(Mathematical Biosciences and Engineering, 2021-08)
We present a compartmental model in ordinary differential equations of malaria disease transmission, accommodating the effect of indoor residual spraying on the vector population. The model allows for influx of infected ...
Quasi-uniform structures determined by closure operators
(Elsevier, 2021)
We demonstrate a one-to-one correspondence between idempotent closure operators and the so-called saturated quasi-uniform structures on a category C. Not only this result allows to obtain a categorical counterpart P of the ...
An SEIR model with infected immigrants and recovered emigrants
(Springer Science and Business Media Deutschland GmbH, 2021)
We present a deterministic SEIR model of the said form. The population in point can be considered as consisting of a local population together with a migrant subpopulation. The migrants come into the local population for ...
A stochastic population model of cholera disease
(American Institute of Mathematical Sciences, 2022-02)
A cholera population model with stochastic transmission and stochasticity on the environmental reservoir of the cholera bacteria is presented. It is shown that solutions are well-behaved. In comparison with the underlying ...
Mathematical modeling and impact analysis of the use of COVID alert SA app
(AIMS Press, 2022)
The human life-threatening novel Severe Acute Respiratory Syndrome Corona-virus-2
(SARS-CoV-2) has lasted for over a year escalating and posing simultaneous anxiety day-by-day globally since its first report in the late ...
