Currently a large scale infrastructural mall development of 48000 m is being constructed adjacent to the Mooi River in the central business district of the city of Potchefstroom. This development is facing significant environmental and social challenges due to the highly sensitive environment in which the development is being constructed. In projects like the Mooirivier Mall Development the act...

Existing e-commerce applications on the web provide the users a relatively simple, browser-based interface to access available products. Customers are not provided with the same shopping experience as they would in an actual store or mall. This experience, however, can be achieved by the creation of a virtual shopping mall environment, simulating most of the actual shopping user interactions. T...

We have implemented and tested a PDA-based system that gives a shopper directions through a shopping mall on the basis of (a) the types of products that the shopper has expressed an interest in, (b) the shopper’s current location, and (c) the purchases that the shopper has made so far. The system uses decision-theoretic planning to compute a policy that optimizes the expected utility of a shopp...

This study was designed to investigate the benefit of inclusion of various verbal elements in 3D talking-head on pronunciation learning among non-native speakers. In particular, the study examines the effects of three different multimedia presentation strategies in 3D talking-head Mobile-Assisted-Language-Learning (MALL) on the learning achievement of students with low English pronunciation ski...

At an intermediate stage of radiation treatment planning for IMRT, most commercial treatment planning systems for IMRT generate intensity maps that describe the grid of beamlet intensities for each beam angle. Intensity map segmentation of the matrix of individual beamlet intensities into a set of MLC apertures and corresponding intensities is then required in order to produce an actual radiati...

Expressions for the average intensity of both phase-locked and non-phase-locked Airy array beams propagating through atmospheric turbulence are derived based on the extended Huygens–Fresnel principle. The evolution of the average intensity distribution of both phase-locked and non-phase-locked Airy array beams during propagation in atmospheric turbulence is examined by numerical examples and is...
