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.”

Department arranges special excursion for disabled students
2008-11-26

 

The unique circumstances of students with disabilities often make it difficult for them to attend educational excursions of the Department of Communication and Information Studies. A special excursion was thus arranged for them to the National Museum in Bloemfontein. Work was recently done to make the museum more accessible for persons with disabilities. A lift was installed and exhibitions are equipped with Braille. Many exhibitions are equipped with sound and visitors can also make use of audio players.

Mr Tebogo Mohlakane, educational officer from the National Museum, and a team of well-trained museum guides welcomed the 13 students that were accompanied by Ms Elbie Lombard and other members of the department with open arms. Each student received special attention to make it an unforgettable experience.

Estine Smith, a first-year student with visual impairments, summarised her experience of a stuffed predatory bird which she held in her arms, as awesome. Touching replicas of elephants, rhinos and giraffes was the highlight of Shaun Jooste, a third-year student with visual impairments’ experience. Until recently it was difficult for Tshidiso Molehe to visit the museum with his wheelchair. He is now satisfied with the accessibility of the museum and is looking forward to his next visit to the museum.
