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 Business School positioned as key partner in the fight against fraud
2016-11-21

A collaborative effort to curb the scourge of fraud in public and private companies has been identified as the most effective method at the launch of International Fraud Awareness week, 13-19 November.  The programme kicked off with a media briefing held in Bloemfontein, under the theme: “Curb Fraud and Accelerate Economic Transformation”.  At this occasion, the Free State Provincial Treasury and key partner institutions which are: UFS Business School, Standard Bank, Association of Certified Fraud Examiners (ACFE), and PricewaterhouseCoopers, made a pronouncement on their efforts to stop fraud in public and private institutions.

Strategic partnerships empower companies
The UFS Business School, in collaboration with Strategic Investigations and Seminars, formed a collaborative effort to present the Advanced Certificate in Fraud Examination, thus empowering individual companies to have within their ranks, certified fraud examiners.  The programme is a registered SAQA, NQF level 7 course comprising four modules; Law, Investigation, Fraud Prevention, Detection and Ethics, Financial Transactions and Fraud Schemes. Students are assisted to continue to the ACFE Board examination in order to become internationally accredited. In 2016, a new e-learning model was introduced to decrease the time spent away from the workplace, thereby encouraging more professionals to enrol.

Commitment is key driving force
Speaking at the media briefing, Jo’Anni Deacon, Senior Officer at the UFS Business School, said “by presenting the programme, the university had positioned itself as a key partner with provincial government and other entities in the fight against fraud”.

Head of Department in the Free State Provincial Treasury, Godfrey Mahlatsi, reiterated the stance of zero tolerance against fraud, and that the department was committed to ensuring that this partnership continued to grow, enabling all to strengthen the message that fraud and corruption undermined the goals and objectives of the National Development Plan.

Gerhard Geldenhuys, Director of PwC Forensic Services said: “I believe we are making a difference and further believe that the time for dialogue on fraud is now better than ever.”

The week-long campaign encourages employees (both in the public and private sector), and business leaders, to proactively take action to minimise the impact of fraud in their environments.
