Optimal control of HIV/AIDS in the workplace in the presence of careless individuals
(Hindawi Publishing Corporation, 2014-06-26)A nonlinear dynamical system is proposed and qualitatively analyzed to study the dynamics of HIV/AIDS in the workplace. The disease-free equilibrium point of the model is shown to be locally asymptotically stable if the ...

Computational dynamics of arterial blood flow in the presence of magnetic field and thermal radiation therapy
(Hindawi Publishing Corporation, 2014-04-22)We conduct a numerical study to determine the influence of magnetic field and thermal radiation on both velocity and temperature distributions in a single blood vessel. The model here assumes that blood is a Newtonian ...

Application of successive linearisation method to squeezing flow with bifurcation
(Hindawi Publishing Corporation, 2014-01-02)This paper employs the computational approach known as successive linearization method (SLM) to tackle a fourth order nonlinear differential equation modelling the transient flow of an incompressible viscous fluid between ...

Unsteady hydromagnetic flow of radiating fluid past a convectively heated vertical plate with the Navier slip
(Hindawi Publishing Corporation, 2014-04-17)This paper investigates the unsteady hydromagnetic-free convection of an incompressible electrical conducting Boussinesq’s radiating fluid past a moving vertical plate in an optically thin environment with the Navier slip, ...

Analysis of heat transfer in Berman flow of nanofluids with Navier slip, viscous dissipation, and convective cooling
(Hindawi Publishing Corporation, 2014-03-31)Heat transfer characteristics of a Berman flow of water based nanofluids containing copper (Cu) and alumina (Al2O3) as nanoparticles in a porous channel with Navier slip, viscous dissipation, and convective cooling are ...

The background radiation and exposure levels at various South African west coast military units
(Stellenbosch University. Faculty of Military Science (Military Academy), 2014)The West Coast of South Africa between St Helena Bay to the north and Langebaan Lagoon to the south is characterised by numerous granite protrusions. These outcrops are elements of the underlying Cape Granite Suite, which ...

The flow of a variable viscosity fluid down an inclined plane with a free surface
(Hindawi, 2013)The effect of a temperature dependent variable viscosity fluid flow down an inclined plane with a free surface is investigated.The fluid film is thin, so that lubrication approximation may be applied. Convective heating ...

Natural convection of viscoelastic fluid from a cone embedded in a porous medium with viscous dissipation
(Hindawi, 2013)We study natural convection from a downward pointing cone in a viscoelastic fluid embedded in a porous medium. The fluid properties are numerically computed for different viscoelastic, porosity, Prandtl and Eckert numbers.The ...

New developments in fluid mechanics and its engineering applications
(Hindawi, 2013)Fluid mechanics is an active field of research with many unsolved or partially solved problems in science and engineering. Fluid mechanics can be mathematically complex. Sometimes the problems can best be solved by ...

Mapping of historical human activities in the Saldanha Bay military area by using in situ gamma ray measurements
(Faculty of Military Science, Stellenbosch University, 2012)Saldanha Bay on the west coast of South Africa is surrounded by various nature reserves, military units and training sites. Over a long period of time, large parts of this semi-arid area were exposed to human activities, ...
