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.

UFS adopts advanced institutional approach to disability, launches CUADS

The approach to support for students with disabilities at South African universities has remained largely one-dimensional, focusing on the support and accommodation of individual students. Implementing the Universal Access (UA) and Universal Design (UD) approach has aligned the University of the Free State (UFS) with international standards. Such an approach addresses challenges arising as a result of the interaction between functional limitations and the social, attitudinal and physical environment of students with disabilities. The Unit for Students with Disabilities (USD) has evolved into the Center for Universal Access and Disability Support (CUADS) in support of the social model of disability. 

Hetsie Veitch, Head of CUADS and her team, have dedicated the past four years to the center’s physical revamping and systematic reconstruction to be officially launched in an Open Day event on the Bloemfontein Campus.


Details of the event:
Date: Friday 24 July 2015
Time:10:00-16:00
Venue: CUADS and Sasol Library foyer
Members of the public are welcome to attend.

Exploring the dimensions of UA and UD

UA and UD facilitate holistic support for students with visual, mobility, hearing, learning, and other impairments. With the former providing a paradigm shift in disability management and support, the latter warrants the formation of a universally accessible environment.

According to Veitch, the focus moves away from the person with the disability, someone who ‘needs to be helped’, to the environment in which that person needs to function.

Since the center was founded in 2001, structural and systematic developments have occurred in order to create a welcoming and accessible learning environment that grants students opportunities to be successful in their academic endeavours.

UA endorses the UFS Mission Statement of human togetherness, advancing social justice by creating multiple opportunities for students to access the university, and promoting innovation, distinctiveness, and leadership in both academic and human pursuits.The UFS is committed to be a welcoming, accessible, and inclusive learning institution, an environment where optimal learning for a diverse student community thrives.
