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.

Research conducted on economic impact of recent international soccer and rugby matches for Bloemfontein
2004-09-09

The Centre for Development Support at the University of the Free State (UFS) recently conducted a survey on the economic impact of the international soccer and rugby games that were played in Bloemfontein earlier this year.

The research focused on the soccer match between Bafana Bafana and the Cape Verdic Isle and the rugby match between the Springboks and Ireland .

“The survey was done as a result of a research agenda about local economic development in Bloemfontein ,” said Dr Lochner Marais, researcher at the centre.

“We conducted the research by doing 402 interviews with soccer supporters and 376 interviews with rugby supporters from outside Bloemfontein ,” said Dr Marais.

The centre distributed questionnaires, collecting the following information on the soccer and rugby supporters: their age, gender and origin, the number of nights spend in Bloemfontein , their household expenditure in Bloemfontein and their rating on the quality of service.

“It is estimated that 10 800 soccer supporters and 27 000 rugby supporters came from outside Bloemfontein . Of the rugby supporters 14,4% were female and 85,6% were men. For the soccer international the percentage was 33% females and 67% males,” said Dr Marais.

The highest number of people who came to watch the soccer game in Bloemfontein (35,8%) was from the Northern Free State . The rugby supporters mainly came from Gauteng (21,8%) and the Northern Free State (18%).

When visiting Bloemfontein soccer supporters spend R912 per household, whilst rugby supporters reached deeper in their pockets and spent R1 807 per household.

“The survey indicated that the two international matches resulted in approximately R58 million been spent in Bloemfontein . Rugby supporters were accountable for the largest part (R48 787 205) spent. The largest chunk of the money spent was on accommodation (R14 593 279). On average soccer and rugby supporters from outside Bloemfontein spent 1,4 and 1,9 nights in Bloemfontein ,” said Dr Marais.

Rugby and soccer supporters were also asked to rate the quality of service received from amongst others hotels, guest houses, restaurants, and transport and entertainment facilities. Soccer supporters rated their satisfaction with services higher as rugby supporters. The rugby supporters gave the services at hotels a 3,9 rating, whilst soccer supporters awarded 4,6 rating out of a possible five.
