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.

Johann van Heerden will fly the Kovsie flag high in this year’s International Paralympic Committee (lPC) Swimming Championships in Glasgow. The University of the Free State first-year BEd student is one of 10 South Africans representing our country.

According to the South African Sports Confederation and Olympic Committee, 640 swimmers from about 50 countries are to plunge and stroke their way to the touch plates from 13-19 July.

“I first started swimming because I had a fit when I was born and it caused me to have Cerebral Palsy. My parents thought that, because my right-hand-side functioning was not good, swimming might help strengthen my muscles,” said Johann.

His parents played a major role in influencing the beginning of his professional swimming career.

Lauren van Heerden, Johann’s father, said, “I am so excited for him, and I am proud that he will be representing our country overseas. It is a big competition so it is a good experience for him.”

Qualifying for the IPC championships has proved that hard work pays off. As his coach, Mark Markgraaff, puts it: “Johann must go out there and have fun, most importantly; he will reap the benefits of his hard work.”

It is not only his parents and coach that Johann has made proud; Hetsie Veitch, Assistant Director of the Unit for Students with Disabilities, also expressed how proud she is.

“Since I’ve known him, he has been a very determined young man who is dedicated to his sport.”

The Rio Paralympics is where Johann envisions being next year.
