Prof Maxim Finkelstein, A1-rated researcher from the University of the Free State, has been selected as the 2024 - 2026 Ewha Global Fellow by Ewha Womans University.

An esteemed researcher from the University of the Free State (UFS), Prof Maxim Finkelstein, has been named a 2024 - 2026 Ewha Global Fellow (EGF) by Ewha Womans University in South Korea.

Prof Finkelstein, an A1-rated researcher from the Department of Mathematical Statistics and Actuarial Science, received this honour in recognition of his outstanding collaboration with Prof Ji Hwan Cha from Ewha’s Department of Statistics. Prof Cha nominated him as a leading expert in his field, highlighting their long-standing partnership and significant contributions to mathematical sciences.

According to Hyang-Sook Lee, President of the Ewha Womans University, the EGF programme “encourages distinguished scholars from all over the world to actively collaborate in research and education with Ewha faculty members.”

 

The genesis of a unique collaboration

Prof Finkelstein has collaborated extensively with researchers across Europe and the United States but his partnership with Prof Cha is particularly notable. “I started working at the UFS as a Professor in 1998 when he had just obtained his PhD,” recalls Prof Finkelstein.

At the time, Prof Finkelstein was already an established researcher, while Prof Cha was in the early stages. “His letter to me about one of my articles was sent to me by regular mail to my previous working address in Saint Petersburg, Russia, and did not reach me. We eventually connected around 2006, and our collaboration gradually took shape,” he explains.

Over the years, their partnership evolved into a balanced and mutually enriching research relationship. Their joint efforts have resulted in over 120 published papers and two books, setting new standards in the Mathematical Theory of Reliability and its applications. This collaboration has significantly influenced both their careers and contributed to Prof Finkelstein’s recognition with South Africa’s highest research accolades, including an NRF A1 rating in "Mathematical Sciences" in 2021, following his A2 rating in 2015.

 

A breakthrough in stochastic modelling

One of the major achievements of Prof Finkelstein's collaboration with Ewha has been their pioneering work in stochastic modelling. Their research led to the development of the Generalised Polya Process, a novel model for understanding natural and industrial point events - such as failures in electricity generation, lightning strikes, and hurricanes. By incorporating the ‘history’ of previous events, this model offers a more precise stochastic description of real-world phenomena.

The results of their research have been widely published and have paved the way for further exploration into more complex stochastic processes. Some of their key findings were summarised in the 2018 Springer book Point Processes for Reliability Analysis.

 

Looking ahead: Future collaboration and continued innovation

Despite being in the later years of his career, Prof Finkelstein remains deeply engaged in research and committed to his partnership with Ewha. Due to the challenges posed by the COVID-19 pandemic, his visits to Ewha were limited, but plans are now in place for future visits. During these visits, he will deliver lectures to students and collaborate with faculty members.

For Prof Finkelstein, continuing his nearly two-decade-long collaboration with Prof Cha remains a vital and exciting part of his academic journey.

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.
