- Description: Abstract: The advances of Industry 4.0 lead the transition into the era of complex systems, requiring systems solutions for complex problems, increasing the interest in the development of systems engineers. However, traditional systems thinking may lose its effectiveness in this new context, which leads to a challenge in systems engineering education. This research aims to better prepare systems engineers of the future by addressing the disconnect which exist between systems engineering education at undergraduate level, and the real-life complex systems seen in society today though the implementation of a reverse order life cycle approach. By following the reverse order life cycle approach with a familiar electrical appliance, such as the electric kettle, in the classroom, undergraduate systems engineering students were able to gain the necessary insight and understanding regarding the dynamics of complex systems the underlying systems engineering concepts.

- Description: Abstract: South Africa is currently facing an education dilemma with high numbers of youth unemployment and a growing specialized skills shortage in Science, Technology, Engineering and Mathematics (STEM). STEM problem based learning events, hosted by government and the corporate sector, has shown to improve science and technology literacy and to encourage the youth to pursue tertiary education in the field of science. Unfortunately, schools face a range of challenges which restricts them from participating in these learning methods, depriving learners of the advantages offered by problem based learning. This paper presents a model for the sustainable provision of STEM problem based learning opportunities in South African schools. The presented model is based on a two-team mentoring model which makes problem based learning sustainable in a South African school environments. The Shell Eco Marathon is in its third year, and the students that have passed through the program will now be progressing to university. The impact of this program, therefore, will be become evident by the success of the students’ studies in the near future.

- Description: Abstract: In South Africa there are still more than 1.5 million households which are unlikely to be connected to the utility grid in the near future. These rural communities are faced with economic development, social and environmental challenges brought about as result of not being connect to the utility grid. Renewable energy offers environmentally favourable and cost effective solutions which are attractive for rural development of communities not connected to the utility grid. Gwakwani is an off-grid rural village situated in northern Limpopo South Africa. As a result of being off-grid, economic and social development of the village was haltered and become near stagnant. In this paper a renewable solar energy solution is utilised in the Gwakwani rural off-grid community for the powering of a small bakery. A solarised container bakery was developed and installed in the community. The bakery operated by four bakers is capable of producing up to 160 loafs of bread per day. The bakery has become the main supplier of bread to the neighbouring communities and is now the largest source of income and employment in Gwakwani, driving economic development. An overview of the technical implementation, bakery operation as well as the social aspects are presented. Social development was facilitated through the training of community members on the operation of the bakery and the economic business development thereof. Results from the social and economic impact of the off-grid solar bakery are presented and discussed.

- Description: Abstract: Problem-based learning has proven to develop teamwork, problem solving skills, communication and critical thinking skills amongst learners. Due to these advantages, secondary schools in South Africa engage with problem-based events to promote the participation of learners in Science, Technology, Engineering and Mathematics (STEM). However, many schools face lack of time, lack of available funds and lack of the required technical skill set, which limits them from participating in these events. The Car-In-a-Box concept was developed to broaden access to a STEM problem-based learning event, called the Shell Eco-Marathon. The Car-In-A-Box concept addresses the three challenges that would normally prevent a school from entering the Shell Eco-Marathon, disenabling learners to harness the advantages of problem-based learning. The impact of the Car-In-A-Box concept for broadening access to problem-based learning is discussed.

- Description: Abstract: Since the era of the economic adjustment program, the Zimbabwe Electricity Supply Authority (ZESA) Holdings has been faced with an increasing problem of non-payment of electricity service charges, especially in the medium- to low-income households. In the early 2000s, the power utility company resorted to disconnections and the removal of post-paid electricity meters for non-paying households. Many customers accused ZESA Holdings of overcharging them on their monthly bills through the post-payment plan. As a way of recovering costs from non-paying households, ZESA Holdings resorted to the deployment of prepaid electricity meters, which automatically disconnect when households pre-coded electricity tokens are used up. The objective of this study is to understand consumers’ perception of the use of prepaid electricity meters versus the post-paid system, in Chidzidzi, Mutoko, Zimbabwe. Lessons learnt from this study are useful for informing policy in the country and other developing countries.

- Description: Abstract: Globally, universities are reinventing STEM education where traditional classroom methods are substituted or supplemented with practical learning methods such as problem-based learning and project-based learning. Another method, not often employed in STEM, is learning through reflection. This paper presents a case study where a group of engineering students participated in an international competition, the Shell Eco-Marathon, and partook in reflective learning before and after the event. The results indicate that students who learn through reflection value the inclusion of project-based learning in their curricula, which emphasizes the importance of this study for the future of engineering education.

- Description: Abstract: Multifunctional devices are employed in office networks for functionality and comfort, most often considered only as peripheral devices enabling the printing, copying and scanning of documents. Based on a study performed by InfoTrends in 2013 in the USA and Western Europe, the majority of people surveyed are of the opinion that computers pose the biggest security threats of all technological devices (Forbes, 2017a). In many cases, users of multifunctional devices do not realise that a multifunctional device is also a network device which have similar vulnerabilities, whereby the security threats relating to these devices are often overlooked. This paper provides an overview of the physical and network security risks relating to networked multifunctional devices. It includes a number of experiments and tests performed on multifunctional devices, security analysis, discussions on possible exploits as well as recommendations on various security measures. This paper could serve as a high-level guideline when installing multifunctional devices in a network environment and informing administrators and users of the security risks associated with installation and daily use.
