Tennis team countrys fourth-best
The Kovsies first tennis team is from left Cornelius Rall, Lienke de Kock, Reze Opperman and Arne Nel (captain).

The first tennis team of the University of the Free State (UFS) obtained a respectable fourth place at the Top Guns Club event that finished at Sun City on Monday 19 February 2018.

It was the first time the tournament was held where all the provincial tennis champs competed for the honours as national club champions.

The Kovsie team was represented by Cornelius Rall, Lienke de Kock, Reze Opperman and Arne Nel. Arne a veteran who has played for the first team for six years, led the team. They played as men’s doubles, women’s doubles and mixed doubles with optional rotation at the end of each set.

The round robin matches consisted out of three full short sets. Thus, the first team to four games, by a margin of two would win the set.

Student crown to defend
The Free State students topped their pool with three wins from three encounters.

Victories came against Lapésa Tennis Club of the Northern Cape, Wesbank from Eden and Cradock from Eastern Province, all by 3-0.

It set up an encounter with Camps Bay from the Western Cape in the semi-finals which the Kovsies lost by 1-2.

In the play-off for third and fourth place the students came unstuck against Marks Park Tennis Club from Gauteng Central.

The Kovsies will next be in action from 13 to 16 April 2018 again in Sun City in a university challenge tournament which they have won for the previous two years.

They boast an outstanding record in student competitions, having won the University Sport South Africa (Ussa) the last eight years consecutively.

Dr Abdon Atangana cements his research globally by solving fractional calculus problem
2014-12-03

 

Dr Abdon Atangana

To publish 29 papers in respected international journals – and all of that in one year – is no mean feat. Postdoctoral researcher Abdon Atangana at the Institute for Groundwater Studies at the University of the Free State (UFS) reached this mark by October 2014, shortly before his 29th birthday.

His latest paper, ‘Modelling the Advancement of the Impurities and the Melted Oxygen concentration within the Scope of Fractional Calculus’, has been accepted for publication by the International Journal of Non-Linear Mechanics.

In previously-published research he solved a problem in the field of fractional calculus by introducing a fractional derivative called ‘Beta-derivative’ and its anti-derivative called ‘Atangana-Beta integral’, thereby cementing his research in this field.

Dr Atangana, originally from Cameroon, received his PhD in Geohydrology at the UFS in 2013. His research interests include:
• the theory of fractional calculus;
• modelling real world problems with fractional order derivatives;
• applications of fractional calculus;
• analytical methods for partial differential equations;
• analytical methods for ordinary differential equations;
• numerical methods for partial and ordinary differential equations; and
• iterative methods and uncertainties modelling.

Dr Atangana says that, “Applied mathematics can be regarded as the bridge between theory and practice. The use of mathematical tools for solving real world problems is as old as creation itself. As written in the book Genesis ‘And God saw the light, that it was good; and divided the light from the darkness’, the word division appears here as the well-known method of separation of variables, this method is usually employed to solve a class of linear partial differential equations”.

“A mathematical model is a depiction of a system using mathematical concepts and language. The procedure of developing a mathematical model is termed mathematical modelling. Mathematical models are used not only in natural sciences, but also in social sciences such as economics, psychology, sociology and political sciences. These models help to explain systems and to study the effects of different components, and to make predictions about behaviours.”
