Numerical simulation of pressure response in partially completed oil wells.
(2002)This work is concerned with the application of finite difference simulation to modelling the pressure response in partially penetrating oil wells. This has relevance to the oil and hydrology industries where pressure ... -
Numerical simulation of quantum spins in a dissipative environment.
(2016)When modelling real physical systems, one should always consider the influence of the environment. The study of open quantum systems aims precisely at the assessment of the role of the environment in the evolution of ... -
Numerical simulation of the structural response of a composite rocket nozzle during the ignition transient.
(2009)The following dissertation describes an investigation of the structural response behaviour of a composite solid rocket motor nozzle subjected to thermal and pressure loading during the motor ignition period, derived on ... -
Numerical simulations of fundamental light-matter interactions.
(2017)We present the results of the numerical investigations of light-matter interactions in one and two dimensions from the quantum mechanical perspective. We investigate the dynamics of two-level systems coupled to quantized ... -

A numerical study of entropy generation, heat and mass transfer in boundary layer flows.
(2018)This study lies at the interface between mathematical modelling of fluid flows and numerical methods for differential equations. It is an investigation, through modelling techniques, of entropy generation in Newtonian ... -
A numerical study of heat and mass transfer in non-Newtonian nanofluid models.
(2019)A theoretical study of boundary layer flow, heat and mass transport in non-Newtonian nanofluids is presented. Because of the diversity in the physical structure and properties of non-Newtonian fluids, it is not possible ... -
Nurses experiences of work engagement : a qualitative study.
(2012)South African nurses are emigrating for greater prospects abroad – a weakening of the healthcare system. Nurses play a critical role in health care globally as well as in South Africa. Work engagement or lack thereof may ... -
Nurses' religious and cultural beliefs and its influences on healthcare provision for women seeking termination of pregnancy : a case study of Grey's hospital.
(2014)The political liberation of South Africa in 1994 gave its people the right to freedom of expression, thought and religion. This has led to the promulgation of the Choice of Termination of Pregnancy Act of 1996 (Act No. 2 ... -
