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.

It was a year of various highlights for the University of the Free State (UFS) which has again illustrated the institution’s versatility by excelling on various fronts, from sports to research.

Some of these included Wayde van Niekerk winning a gold medal at the Olympic Games in Rio de Janeiro; research on the locomotion of the giraffe, and the awarding of honorary doctorates to people such as veteran journalist Max du Preez.

Van Niekerk breaks 400m world record

After his feat in Rio on 14 August 2016, Van Niekerk was described as “the next star” by former US sprinter Michael Johnson, whose 17-year-old 400m world record he broke in a time of 43,03. Johnson described the way in which the Kovsie outperformed the 400m field as “a massacre”.

Wayde van Niekerk was described as “the next star" by Michael Johnson, whose 17-year-old 400m world record he broke in a time of 43.03.


Max du Preez and Trevor Manuel honoured


Du Preez (Humanities) said he was excited about the young minds he had interacted with at the Winter Graduation ceremony of the UFS. The leading journalist and political analyst was one of four recipients of honorary doctorates from the university on June 30 2016. The others were Prof Joel Samoff (Humanities), former finance minister Trevor Manuel, and Dr Reuel Jethro Khoza (both Economic and Management Sciences.

Research of great value for conservation


Dr Francois Deacon, Department of Animal, Wildlife, and Grassland Sciences at the UFS, and Dr Chris Basu, a veterinarian at the Royal Veterinary College in the UK, conducted research on the manner in which giraffes locomote from one place to another.

Very little research has been done on the manner in which these animals move. The research will assist in understanding aspects such as the giraffe’s anatomy and function, as well as the energy it utilises in locomoting. Such information could help researchers understand where giraffes fit into the ecosystem and the data would be of great value for large-scale conservation efforts.
