The 2009 intake of university students were the first to have received complete school education within the recently implemented Outcomes‐Based Education (OBE) system. A feature of the matriculation examination results of these students was the exceptionally high Grade 12 marks for Mathematics. This paper addresses the question of how the 2009‐ intake of students performed at university with respect to general performance, general attributes, mathematical attributes and content related attributes. ...

This paper presents a range of methods for computing the equilibrium configuration of shopping facility sizes. First, the presently available range of quasi-balancing factor methods is considered and built into a theoretical framework in which further algorithms may be defined. Then the use of the gradient method is considered, which is a general method of solution of nonlinear equations. Last, it is shown that a special case exists in which a closed form solution may be obtained.

Results are presented of a test case conducted to compare the assessment of mathematics students by open book tests and closed book examination. The results show that: (i) the grades obtained in open book tests are comparable with those obtained in closed book tests; and (ii) open book tests are a better discriminator among students than closed book tests.

This paper is a result of an investigation to come up with a new hybrid scheme for solving second order (1+1) boundary value problems of linear as well as nonlinear partial differential equations with non-homogeneous Dirichlet boundary conditions. Such an innovation is significant since there are not many analytical methods for solving partial differential equations with boundary data. The scheme involves the coupling of the ModDTM, a modified form of the Differential Transform Method, and the Adomian ...

The Modified Adomian Decomposition Method (MADM) is presented. A number of problems are solved to show the efficiency of the method. Further, a new solution scheme for solving boundary value problems with Neumann conditions is proposed. The scheme is based on the modified Adomian decomposition method and the inverse linear operator theorem. Several differential equations with Neumann boundary conditions are solved to demonstrate the high accuracy and efficiency of the proposed scheme.

The Differential Transform Method is a powerful analytical method that can solve nonlinear partial differential equations. Yet, the method cannot be used to solve time-dependent partial differential equations that involve more than one partial derivative with respect to the temporal variable t when they are of the same order, as in the case of the Fornberg-Whitham type equations. In this paper, a new theorem is devised to overcome the aforementioned problem ofthe method, and it has been successfully ...

This paper presents a modification of the Differential Transform Method (ModDTM) formulated so that the search direction of the solution is along a spatial axis ( x ). It is shown that the method is applicable to a wide spectrum of (1 + 1) partial differential equations, integro partial differential equations, and integral equations. The solutions obtained are in the form of a Taylor series, the coefficients of which are determined by recursively operating a differential transform of the equation. These ...

In this study, we constructed and analysed a mathematical model of COVID-19 in order to comprehend the transmission dynamics of the disease. The reproduction number (RC) was calculated via the next generation matrix method. We also used the Lyaponuv method to show the global stability of both the disease free and endemic equilibrium points. The results showed that the disease-free equilibrium point is globally asymptotically stable if RC RC > 1. We further used the Adomian decomposition method and ...

The loss of a baby during the perinatal period leads to a real grieving process for mothers since they establish an attachment bond with their baby before birth. If relatives and environment bereaved underestimate this particular type of bereavement and its potential impact, this should not be the case for nursing staff. And yet, in African maternities, there are very few psychological support for mothers who are victims of perinatal death. Perinatal bereavement deserves to be analyzed in all its ...

In this paper, we present the New Modified Adomian Decomposition Method which is a modification of the Modified Adomian Decomposition Method. The new method incorporates the inverse linear operator theorem into the modified Adomian decomposition method for the calculation of u0. Six linear and nonlinear boundary value problems with Neumann conditions are solved in order to test the method. The results show that the method is effective.

This paper considers evaluation of the general class of integrals of the form using the Adomian decomposition method. This integral is solved in its general form and it is shown that particular values of of this class of integrals correspond to Mellin and Gaussian integrals whose solutions are easily obtained. Key words: General class of integrals, Adomian decomposition, Mellin integrals, Gaussian integrals.

Following the political changes of 1994 in South Africa, the decision was taken to replace the traditional skills-based education system at primary and secondary school level (Grades 1 - 12) with an outcomes-based education system (OBE). The OBE approach, referred to as Curriculum 2005, was introduced into schools in 1998. The implementation of the OBE system did not occur without problems, giving rise to revised initiatives and a fair amount of criticism. The 2009 intake of students at universities ...
