Strategies to reduce traffic accident rates in developing countries: lessons learned for assessment and management
(WIT Press, 2018)Strategy formulation and approaches in assessment and management of traffic engineering challenges related to the impact of traffic accidents on road networks in developing countries is problematic. The core focus of this ... -
Standard versus strict bounded real lemma with infinite-dimensional state space. I. The state-space-similarity approach
(Theta Foundation, 2018)The bounded real lemma, i.e., the state-space linear matrix inequality characterization (referred to as Kalman--Yakubovich--Popov or KYP-inequality) of when an input/state/output linear system satisfies a dissipation ... -
A study of the stability properties of Sagdeev solutions in the ion-acoustic regime using kinetic simulations
(AIP, 2018)The Sagdeev pseudo-potential approach has been employed extensively in theoretical studies to determine large-amplitude (fully) nonlinear solutions in a variety of multi-species plasmas. Although these solutions are ... -
Optimizing tracking error-constrained portfolios
(Taylor & Francis, 2018)Active portfolios subject to tracking error (TE) constraints are the typical setup for active managers tasked with outperforming a benchmark. The risk and return relationship of such constrained portfolios is described ... -

(Springer, 2017)As fourth-year Information Technology students make the transition from under-graduate studies towards a post-graduate degree, an honours research project may be a daunting task (For readers from outside South Africa: the ... -
Games for learning in accountancy education: a systematic literature review
(The Social Sciences Research Society, 2017)Background: Games for learning (educational games) are viewed as instructional strategies requiring students to engage in competitive activities with predetermined rules and conditions. Various studies propose beneficial ... -
Does the early adopter catch the worm or choke on it? A reflective journey of the challenges of technology adoption in a health sciences education institution
(Taylor & Francis, 2017)Background: Early adoption of technology is a struggle well known to early adopters and now to me. Since the demand to use and implement technology in health professions' education has increased, I have been led to adopt ... -
Computational modelling and optimal control of Ebola virus disease with non-linear incidence rate
(IOP Publishing, 2017)The 2014 Ebola outbreak in West Africa has exposed the need to connect modellers and those with relevant data as pivotal to better understanding of how the disease spreads and quantifying the effects of possible interventions. ... -
Success factors for serious games to enhance learning: a systematic review
(Springer, 2017)There is no doubt that an abundance of factors exists that makes learning with serious games successful. Research articles reporting on these factors, however, tend to focus on select serious game elements and do not combine ... -
The use of critical systems heuristics to surface and reconcile users' conflicting visions for a business intelligence system
(Springer, 2017)This paper describes an action research study where the business requirements analysis approach of a business intelligence development project was enriched. Critical systems heuristics, a critical systems methodology that ... -
Speech recognition for under-resourced languages: data sharing in hidden Markov model systems
(Academy of Science of South Africa (ASSAf), 2017)For purposes of automated speech recognition in under-resourced environments, techniques used to share acoustic data between closely related or similar languages become important. Donor languages with abundant resources ... -
Interactive game for children with difficulty crossing the midline
(IEEE, 2018)By the age of five years, a child ought to have mastered the corresponding expertise of bilateral integration, utilizing both sides of the body simultaneously, called “crossing the midline”. This means that when a child ... -
Moving households to cleaner energy through air quality offsets
(IEEE, 2018)Highest levels of exposure to polluted air in South Africa occur in low-income settlements where households burn solid fuels. The Department of Environmental Affairs has recently developed a legally enforceable mechanism ... -
Theoretical perspectives on resilience and sustainability in transportation and spatial planning
(WIT Press, 2018)The debate on sustainability and resilience is dealt with by many authors working within the environmental, ecological and human settlement planning domains. These concepts and its interface can hardly be separated form ... -
