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 keeps the power on
2015-06-24

 

At a recent Emergency Power Indaba held on the Bloemfontein Campus, support structures at the university met to discuss the Business Continuity Intervention Plan to manage load shedding on the three campuses of the UFS.

Currently, 35 generators serving 55 of the buildings have already been installed as a back-up power supply on the three campuses of the university. According to Anton Calitz, Electrical Engineer at the UFS, the running cost to produce a kWh of electricity with a diesel generator amounts to approximately three times the cost at which the UFS buys electricity from Centlec.

Planned additional generators will attract in excess of R4 million in operating costs per year. For 2015, the UFS senior leadership approved R11 million, spread over the three campuses. Remaining requirements will be spread out over the next three years. University Estates is also looking at renewable energy sources.

On the Bloemfontein Campus, 26 generators serving forty-one buildings are in operation. On South Campus, two generators were installed at the new Education Building and at the ICT Server Room. Lecture halls, the Arena, the Administration Building, and the library will be added later in 2015. Eight generators serving 12 buildings are in operation on the Qwaqwa Campus. In 2015, the Humanities Building, Lecture Halls and the heat pump room will also be equipped with generators.

Most buildings will be supplied only with partial emergency power. In rare cases, entire buildings will be supplied because the cost of connecting is lower than re-wiring for partial demand. According to Nico Janse van Rensburg, Senior Director at University Estates, emergency power will be limited to lighting and power points only. No allowances will be made for air-conditioning.

“Most area lighting will also be connected to emergency power,” he said.

Where spare capacity is available on existing emergency power generators, requests received for additional connections will be added, where possible, within the guidelines. The following spaces will receive preference:
- Lecture halls with the lights, data projectors, and computers running
- Laboratories for practical academic work and sensitive research projects
- Academic research equipment that is sensitive to interruptions
- Buildings hosting regular events

According to Janse van Rensburg, all further needs will be investigated. Staff can forward all emergency power supply needs to Anton Calitz at calitzja@ufs.ac.za

Staff and students can also manage load shedding in the following ways:

1. Carry a small torch with you at all times, in case you are on a stairwell or other dark area when the lights go out. You can also use the flashlight app on your phone. Download it before any load shedding occurs. This can come in handy if the lights go out suddenly, and you cannot find a flashlight. Load-shedding after dark imposes even more pressure on our Campus Security staff. We can assist them with our vigilance and preparedness by carrying portable lights with us at all times and by assisting colleagues.
2. Candles pose a serious safety risk. Rather use battery- or solar-powered lights during load shedding.
3. Ensure that your vehicle always has fuel in the tank, because petrol stations cannot pump fuel during power outages.
4. Ensure that you have enough cash, because ATMs cannot operate without electricity.
5. The UFS Sasol Library has study venues available which students can use during load shedding.
6. When arranging events which are highly dependent on power supply, especially at night, organisers should consult the load-shedding schedule before determining dates and preferably also make back-up arrangements. If generators are a necessity, the financial impact should be taken into consideration.

The senior leadership also approved a list of buildings to be equipped with emergency power supplies.
