UFS researcher publishes the highest-cited Maths paper in the world in 2017
An article by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies received New Hot Paper status from Clarivate Analytics.
An article on Applied Mathematics, published by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies in 2017, was recently named New Hot Paper by Clarivate Analytics.

Hot paper status
Essential Science Indicators (ESI) is a unique and comprehensive compilation of science performance statistics and science trends. Data is based on journal article publication counts and citation data from Clarivate Analytics that enables researchers to conduct ongoing, quantitative analyses of research performance and track trends in science. Covering a multidisciplinary selection of 1 2000+ journals from around the world, this in-depth analytical tool offers data for ranking papers, scientists, institutions, countries, and journals. 

ESI from Clarivate Analytics is updated every two months. The New Hot Papers, which are papers published in the past two years, are in the top one-tenth of one percent (0.1%) for their field and publication period. Prof Atangana’s paper had the highest cite count in the field of Mathematics. 

His article that received the New Hot Paper status is titled: “The new fractional derivative and application to nonlinear Fisher’s reaction-diffusion equation”.

The concept of fractional differential operators with non-singular kernel has captured the minds of several researchers in the past year due to their wider applicability in almost all fields of science, engineering and technology. The new fractional differential operators have opened new windows to model complex real-world problems that could not be modelled using the Newtonian and the well-known Riemann-Liouville fractional differential operators. 

“These operators are the way forward in modelling real-world problems in all disciplines, as they are able to include into mathematical formulation the effect of memory,” Prof Atangana said.

The Atangana-Baleanu fractional derivative
The professor developed a new fractional differential operator, called the Atangana-Baleanu fractional derivative. This 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.”

Measures to ensure safer campuses are investigated
2010-04-16

The safety of students, lecturers and staff of the University of the Free State (UFS) is of the utmost importance for the management of this institution and deliberations are continuously taking place on what can be done to improve the levels of safety of the respective campuses in Bloemfontein and Qwaqwa.

A set of recommendations was recently tabled by our rectorate that make provision for various measures for safer campuses. According to Prof. Niel Viljoen, Vice-Rector: Operations at the UFS, attention will urgently be paid to the following recommendations:

  • The instalment of alarm systems, linked to the central security control room, in all buildings on the respective campuses.
  • The instalment of “panic systems” in strategic places in buildings.
  • Where possible, better admission control to buildings, especially office blocks.
  • Better management en integration of contracted-in security workers.
  • Enhancement/upgrading and better monitoring of the security control room and sharpening of reaction times in cases of emergency.
  • Repair and maintenance of the current border fencing.
  • A survey was once again done of all the so-called “dark spots” on campus and the instalment more effective lighting are currently in progress.
  • Safeguarding of footways and parking areas by means of cameras and panic systems that will be monitored 24 hours a day, seven days a week.
  • Better and more visible patrolling of the pedestrian walkways and campuses.

Regular and structured feedback regarding the safety situation at all campuses shall also be done.

According to Prof. Viljoen the following recommendations shall also be investigated further:

- The feasibility of the “closing” of the campus, especially in terms of transport implications, costs and effectiveness.
- The possible closing of the small pedestrian gates in order to channel pedestrian traffic through the existing and manned gates.
- The feasibility of the compulsory wearing of ID cards by all personnel, students and temporary workers.
