Dr Ocaya
Dr Richard Ocaya’s research addresses the skills development and transfer millennium goal of many governments globally.

With the Fourth Industrial Revolution becoming a reality, Dr Richard Ocaya’s research is receptive to the fact that Africa and the world need to re-imagine their research. His research focuses on electronic instrumentation design for scientific measurements, computational physics on atomic nano-atomic structures, and semiconducting organic compounds materials built on silicon to realise Schottky devices.

Software developer 
“I develop most of the instrumentation that I apply in my research – both software and hardware,” said Dr Ocaya, a Physics Lecturer and Programme Director: Physics and Chemistry on the UFS Qwaqwa Campus.

“I am active in scientific computing through the computing cluster and software development, mathematical physics for material science modelling, and embedded instrumentation design using microprocessors. I also have deep interest in radio and data telemetry, in which I hold a South African patent issued in 2013. My present international collaborations are with like-minded researchers in similar fields in Saudi Arabia, Turkey, Japan, Egypt, South Korea, and the United States,” he added.

How does his research talk to the real world?
“The driving principle of all areas of my research has always been to deploy cutting-edge research to actual, real-world applications for the immediate betterment of Africans. The areas of my research align closely with the millennium goals of many governments globally, including the Republic of South Africa. These goals pertain to skills development and transfer that position us to better address the challenges of energy, water, and other priorities.”

Dr Ocaya is currently co-promoting a PhD student, having previously supervised one PhD, two MSc, and more than twenty honours students. He is a self-taught electronics and computer programmer, whose curiosity led him to question ‘the voices and music coming from a box; a radio’. “In my quest to satisfy my curiosity, I collected many discarded devices, took them apart, and tried so many circuits, only to have them fail because the theory was lacking. After thousands of failed projects and with me barely thirteen and in lower secondary school, my first ever project actually worked,” he said.

NRF-rating
He is the author of the book Introduction to Control Systems Analysis using Point Symmetries: An application of Lie Symmetries, which is available in all major bookstores such as Amazon, in both print and e-book format. He is a C3 NRF-rated researcher whose work makes a pioneering contribution to the new and growing field of phononics, an independent field of the now established photonics.

“This field will someday lead to improved energy-storage devices and faster processors due to more efficient heat removal from nanodevices,” he concludes.

UFS first to mechanise agricultural technique
2006-05-09

    

Small farmers from Thaba `Nchu were the biggest group attending the farmers day at the UFS Paradys experimental farm.  From the left are Mr David Motlhale (a small farmer from Thaba 'Nchu), Prof Leon van Rensburg (lecturer at the UFS Department of Soil, Crop and Climate Sciences and project leader), Mr Nhlonipho Nhlabatsi (Agricultural Research Council, Glen), Ms Meisie Mthethwa (small farmer from Bloemspruit).  In front is Mr Patrick Molatodi (chairperson of the Tswelopele Small Farmer Association).
 

 

Some of the participants of the farmers day at the UFS Paradys experimental farm were from the left Prof Leon van Rensburg (lecturer at the UFS Department of Soil, Crop and Climate Sciences and project leader, Mr Patrick Molatodi (chairperson of the Tswelopele Small Farmers Association) and Prof Herman van Schalkwyk (Dean: UFS Faculty of Natural and Agricultural Sciences).

UFS first tertiary institution in world to mechanise agricultural technique
The University of the Free State (UFS) is the first tertiary institution in the world to mechanise the in-field rain water harvesting technique on a commercial scale.

The technique was recently demonstrated to about 100 small farmers at the UFS Paradys experimental farm outside Bloemfontein. 

“With this technique rain water is channeled to the plant and in this way food security is increased.  The advantage of the technique for commercial farmers lies in the reduced cultivation of land.  Small farmers will benefit from this because they can now move out into the fields and away from farming in their back yards,” says Prof Leon van Rensburg, lecturer at the UFS Department of Soil, Crop and Climate Sciences and project leader.    

Rain water harvesting is an antique concept that was used by communities before the birth of Christ.  In South Africa the technique is mainly used in the plots of small farmers where they make surface structures by hand. 

"The technique is also used for the first time by the UFS on commercial scale by means of the cultivation of a summer crop on 100 ha at the Paradys experimental farm,” says Prof Leon van Rensburg,

Of the farmers who attended the farmers day most represented about 42 rural communities in the vicinity of Thaba ‘Nchu.  A group of seven from KwaZulu-Natal also attended the proceedings.  These small farmers can for example apply this technique successfully on the 250-300 ha communal land that is available in the Thaba ‘Nchu area. 

The project is funded by the UFS and the National Research Foundation (NRF) and the farmers’ day was funded by the Water Research Commission.
