Prof Abdon Antangana
Prof Abdon Atangana, a Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS) and South Africa’s top-ranked scientist in Mathematics, wants to prepare the next generation of African professors.

A new book written by Prof Abdon Atangana, Professor of Applied Mathematics at the Institute for Groundwater Studies at the University of the Free State (UFS), in collaboration with one of his students, on the flow of groundwater, suggests several new and modified models to better predict anomalous behaviours of the flow and the movement of pollution within complex geological formations.

Mathematical Analysis of Groundwater Flow Models is one of two books Prof Atangana published recently that he wrote with his students. The other, Fractional Stochastic Differential Equations: Applications to Covid-19 Modeling, provides a thorough conversation on the underpinnings of COVID-19 spread modelling. He wrote the book with a postdoctoral fellow, Dr Seda Araz Igret from SIIRT University, Turkey. Since 2016 he has published a total number of six books, some of which are still under evaluation by Springer and Elsevier.

Time to prepare next generation of African professors 

This highly cited researcher is excited about collaborating with his students on projects such as these as he feels it is time for him to prepare the way for the next generation of African professors. Prof Atangana is ranked at No 219 in the world rankings and No 1 in South Africa by Research.com, a leading academic platform for researchers. 

According to the platform, which recently released the 2022 Edition of its Ranking of Top 1000 Scientists in the field of Mathematics, the ranking is based on the H-index metric provided by Microsoft Academic and includes only leading scientists with an H-index of at least 30 for academic publications in the field of Mathematics.

“Both books are important for me because they are first-time published books with my own students. There is a time to prepare the way for yourself and a time to prepare ways for the next generation. It is time for me to prepare the way for the next generation of African professors. I wish that the next time this list (https://research.com/scientists-rankings/mathematics/za) [is released] many of my students [will] appear,” says Prof Atangana.

About his book with Dr Igret, he says it presents the dynamic of COVID-19 spread behaviour worldwide. It is noticed that the spread dynamic followed process with nonlocal behaviours, which resemble power law, fading memory, crossover, and stochastic behaviours. Fractional stochastic differential equations are therefore used to model spread behaviours in different parts of the world. 

“The content coverage includes a brief history of COVID-19 spread worldwide from December 2019 to September 2021, followed by statistical analysis of collected data for infected, death and recovery classes,” says Prof Atangana.

Mathematical analysis of Groundwater Flow Models serves as a valuable resource for graduate and PhD students as well as researchers working within the field of groundwater modelling, says Prof Atangana. It includes features such as:
• Modified numerical and analytical methods for solving new and modified models for groundwater flow and transport 
• New flow and transform models for groundwater transport in complex geological formations 
• Examination of fractal and crossover behaviours and their mathematical formulations

Top-ranking scientist 

Prof Atangana was also recently elected as a fellow of The World Academy of Sciences (TWAS) and received the World Academy of Sciences Award for Mathematics (TWAS -Mohammad A Hamdan, 2020) on 1 November 2021.

Very recently, he was also ranked No 1 in the world in Mathematics, No 186 in the world in all the fields, and No 1 in Africa in all the fields, according to the Stanford list of 2% single-year table.

He was also named among the top 1% of scientists on the global Clarivate Web of Science list. Fewer than 6 200 or 0.1% of the world’s researchers were included on this list in 2019, 2020 and 2021, with fewer than 10 of the scientists hailing from South Africa. 

“While my name is ranked No 1 in South Africa and No 219 in the world, this shows the impact of my research that has been done since 2013. It is worth noting that this ranking disadvantages younger researchers. For example, I got my first publication in 2013 but the researcher who was ranked No 1 started in 1972. To make the ranking fair, the total H-index should be divided by the number of years of publication. I am very proud to see that despite this disadvantage I am still topping in South Africa and am No 219 in the world.”

UFS on energy-saving mode
2009-09-15

The University of the Free State (UFS) has undertaken several measures to reduce energy consumption on the Main Campus in Bloemfontein.

“Part of Eskom’s strategy is that all the main universities must reduce their electricity consumption. Because the university is the second biggest user of electricity in Bloemfontein we have to cut our consumption according to the new energy policy,” said Prof. Niel Viljoen, Chief Director of Operations at the UFS.

“Electricity is also expensive and if we look at global warming and everybody’s responsibility, I think we all have a moral obligation to save energy,” said Prof. Viljoen.

“The energy crisis of January 2008 and beyond, with its load-shedding limitations, was a major driver for the government to introduce the Power Conservation Scheme,” said Mr Anton Calitz, the UFS’s electrical engineer.

The measures put in place by the UFS include amongst others:

The introduction of a solar water-heating system in the residences, which is a first of its kind in Bloemfontein.
An investigation is also being launched into alternatives and the effective heating of rooms in the residences.

Feasibility studies are currently being conducted to determine whether energy saving can be achieved with radiation panels.

Energy-saving lights have been installed in the following buildings: the Architecture Building, Genmin Lectorium, Geology lecture halls, Winkie Direko Building, George du Toit Building, Sasol Library, Francois Retief Building, as well as in the residences. This measure has resulted in massive energy saving.

Energy meters for the Library, Computer Laboratory Building, François Retief Building and Steyn Substation are being planned as the first phase.

Real-time metering will result in every UFS computer user being aware of power consumption on the campus.

New lift motors and control systems that reduce energy consumption have been installed at the Agriculture and the George du Toit Buildings.

In the Computer Laboratory Building the temperature adjusting point for the venues is set at 22 °C and, in the case of new projects, green guidelines are applied.

It is expected that the government and local authorities will bring more pressure to bear on the UFS to save energy. Applications for increased capacity will possibly be linked to energy-saving targets.

This trend will continue until 2014 when additional power stations will be put into operation.

“Our aim is to save 10% on energy consumption,” said Prof. Viljoen.

“Heavy financial penalties will be imposed if a 10% saving is not achieved,” added Mr Calitz.

On average, our energy consumption per day this year is 128,964 kWh as compared to last year’s 119,752 kWh.
