Mathematician makes popular contribution to science Prof Atangana
Prof Atangana is the first African under 40 years of age to be selected as African Academic of Science affiliated in Mathematics. He recently delivered his inaugural lecture and is pictured with Eelco Lukas, Director of the Institute for GroundwaterStudies at the UFS (middle) and Prof Hendri Kroukamp, Acting Vice-Rector: Academic
Prof Abdon Atangana, researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), recently delivered his inaugural lecture on the topic: Understanding God’s Nature with Non-Local Operators.

His research interests are methods and applications of partial and ordinary differential equations, fractional differential equations, perturbation methods, asymptotic methods, iterative methods, and groundwater modelling. Prof Atangana is the founder of the fractional calculus with non-local and non-singular kernels popular in applied mathematics today. He has introduced more than 12 mathematical operators, most of which bear his name (such as the Atangana-Baleanu fractional integral).

He stated: “We will not stop until we change the classical view of doing mathematics. Mathematics is not a subject but a tool given to mankind by God to understand nature. One single mathematical operator cannot portray God’s nature accurately. Therefore the Atangana Baleanu was suggested.”

New weapons

Most physical problems can be expressed in terms of mathematical formulations called differential equations. According to him the differential equation’s aim is to analyse, understand, and predict the future of a physical problem. Prof Atangana introduced the Atangana-Baleanu fractional integral. This brought new weapons into applied mathematics to model complex real-world problems more accurately.

Prof Atangana explained: “The Atangana-Baleanu fractional derivative is able to describe real-world problems with different scales, or problems that change their properties during time and space for instance, the spread of cancer, the flow of water within heterogeneous aquifers, movement of pollution within fractured aquifers, and many others. This crossover behaviour is observed in many empirical systems.”

Sudden change

The Atangana-Baleanu fractional derivative is also able to describe physical or biological phenomena, such as a heart attack, the physiological progression from life to death, structural failure in an aeroplane, and many other physical occurrences with sudden change with no steady state.

The new differential and integral operators are nowadays in fashion and are being applied with great success in many fields to model complex natural phenomena. It is believed that the future of modelling complex real-world problems relies on these non-local operators.

Tactile paving assists visually impaired

Crossing roads and accessing buildings has always been a challenge for people with visual impairments. They had to rely on peripheral sounds, such as car brakes and cues. However, after the installation of tactile paving – paving with special textures assisting the visually impaired to feel the difference between walking around on campus and crossing the road, this will no longer be a problem at the University of the Free State (UFS).

This is one of several developments that University Estates’ Department of Facilities Planning has in the pipeline for 2017 in order to ensure that the university attains its key component in providing a high-quality student experience.

Maureen Khati, Assistant Director of Project Management: Facilities Planning, says, “We saw the need to install these paving blocks in strategic spaces, as identified by the Center for Universal Access and Disability Support (CUADS).” She says these blocks will make it easier for people with visual impairments.

Special features designed to aid visually-impaired persons

 These installations have special features that will assist those students and employees with limited vision or blindness to navigate through pedestrian crossings and the different campus buildings. The university chose a unique design of tactile paving that focuses on warning and directing those with visual impairments.

UFS eager to improve accessibility and mobility

 The university, and all the stakeholders involved in this initiative, are delighted to be embarking on this project and are looking forward to its successful execution. To improve accessibility and mobility, more accessible entrances and exits will be built, effective signage will be installed inside and outside buildings, but the most important aspect is that dedicated seating space will be made available in lecture rooms for special-needs students.

Khati says, “More focus has been put on installing ramps in all buildings to make them more accessible for people with disabilities, as well as other needs required to enhance accessibility at the UFS.”

For the UFS, this initiative is one of many to come, as extensive research is being done and priorities are implemented accordingly.
