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.

School of Open Learning opens at our South Campus
2011-08-23

 

Prof Daniella Coetzee, Dean of the School of Open Learning at our South Campus

The University of the Free State (UFS) established a School of Open Learning at the South Campus in Bloemfontein. The activities of the new school are driven by a central principle: opening up access to those who have not had the opportunity to study at a higher-education institution because of geographical location, socio-economic circumstances or other factors. Programmes are delivered through a blended-learning model, which blends contact teaching with distance education. A new dean, Prof. Daniella Coetzee, was appointed to guide the establishment of the school.

The school will collaborate with the different faculties, and is currently managing the continuing education-sponsored endeavours of the Faculty of Education. These include projects for in-service training of teachers in Mathematics, Natural and Physical Sciences, Languages, Literacy, Economic and Management Sciences, Technology and various areas of Management and Leadership.

Apart from the training of currently serving teachers, the school and the Faculty of Education are also involved in the professional training of FET-college lecturers, and have recently been awarded an R17m injection by the Flemish Government to develop programmes and to further deliver in this area.

Collaboration with the Faculty of Law has also led to the prospect of managing a B.Iuris. programme aimed at the police force, commencing in 2012.

The University Preparation Programme (UPP), offering particular generic and optional subjects for students to enter into the formal university programmes, will also form part of the School of Open Learning.
