UFS information technology students will get exposure to the very latest developments in data science, after a recent exciting partnership was announced between the university and Internet of Things company, IoT.nxt – described by CNBC Africa as “a world leader in technological innovations.”

“The partnership with IoT.nxt will open new opportunities for our students and staff, not only to work with one of the most innovative companies in the country, but also to be exposed to new and creative ways of thinking, all in preparation for the 4th Industrial Revolution (4IR),” says Dr Eduan Kotzé, Academic Head of the UFS Department of Computer Science and Informatics.

“We also believe the partnership will strengthen our academic programme, especially in data science, and prepare our students to be ready for the ever-changing world of technology.”

He explains that it is a huge task to stay at the forefront of technological development. “IoT.nxt's involvement will help us to continually expose our students to trendsetting technologies that is applicable in the industry. It will also ensure that our graduates have the neccessary skills when they enter the job market. In doing so, our curriculum will remain relevant and keep up with new developments in the IT industry,” says Dr Kotzé.

UFS IT excellence

The Department of Computer Science and Informatics at the University of the Free State is widely regarded as one of the best IT departments at a tertiary institution in South Africa. Dr Kotzé believes the fact that we are one of only a few universities who present data science as an undergraduate qualification, followed by an honours qualification, provides us with a competitive edge and differentiates us from other institutions.

“We are also the only university offering a Bachelors Degree in Computer Information Systems aiming to deliver entrepreneurship in technology to make South Africa a role player in the IT industry,” says Dr Kotzé.

Job-ready graduates

He believes the planned short courses will expose students to the latest technology. He is also convinced that the opportunity to become accustomed to the workings of a successful IT company through holiday work, will have a very positive impact on the job readiness of the department’s graduates.

“Because of the pace at which technology is evolving, it is crucial that anyone in the IT industry is already in contact with industry entities that are at the top of the wave, such as IoT.nxt,” says Dr Kotzé.

According to Nico Steyn, IoT.nxt CEO, the support of education drives in the field of technology has been a key focus of his company. Steyn says IoT.nxt selected the UFS for this partnership because it views the university as one of the leading education institutions in this field. There are also UFS graduates among the co-founders.

Direct contact with pioneers

Steyn believes that there is an industry-wide shortage of qualified people in South Africa, and a growing demand for students to graduate with a qualification that meets the requirements of businesses. “Our company, and the vibrant broader technology industry in South Africa, needs such graduates. Through our partnership with the UFS, we will aim to drive interest in this career,” Steyn says.

The partnership with IoT.nxt is one of several industry partnerships that have been entered into by the UFS Department of Computer Science and Informatics over the past few years. “In the IT industry, it is crucial that our curriculum is constantly adapted to remain relevant in a rapidly changing landscape. The relevant skills are determined by the industry and it is therefore a huge advantage to have direct contact with pioneers in that sector,” says Dr Kotzé.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
