Jaco Peyper
Jaco Peyper, former Kovsie, will handle a quarter-final match at the Rugby World Cup. It will also be his 50th test match.
With the appointment of Jaco Peyper as referee there will be Kovsie alumni among the referees, players and coaches in the quarter-finals of the 2019 Rugby World Cup in Japan on 20 October.

Lappies Labuschagné will start on the flank for Japan in their clash against the Springboks on Sunday. Labuschagné, a former Shimla captain, is second on the list for tackles made in the tournament thus far.
In the Springbok camp there are former University of the Free State (UFS) students in Rassie Erasmus (head coach) and Jacques Nienaber (defence coach).

UFS alumnus Jaco Peyper has been entrusted with the whistle in Sunday’s other quarter-final between Wales and France. It will be a memorable match for Peyper as it will be his 50th test appearance as the 31st man on the field – making him only the third South African to achieve this feat.

Peyper, who is the only South African among the 12 referees at the tournament, made his World Cup debut in 2015 when he officiated the opening match. In total he has handled six World Cup encounters. 

His illustrious career has seen him become only the fourth referee in history to officiate in 100 Super Rugby matches earlier in the year, in which he also handled the final (his fourth Super Rugby final). Peyper scooped the SA Referee of the Year award in 2018 for a third time, a year in which he took charge of his fourth Currie Cup Final.

“The fact that he is only the third South African referee to take charge of 50 tests indicates what a special achievement this is. It takes years of hard work and dedication to reach this level as a referee, and to maintain this standard year-in and year-out is even more challenging as it requires one to produce effective performances consistently,” said Jurie Roux, the CEO of SA Rugby.

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.”
