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.

Cochlear implant changes Magteld's world

Magteld Smith gave her first steps towards the world of the hearing when her cochlear implant was switched on in the Universitas Hospital this week.

A whole team was there to share her joy and disbelief and amazement the moment she could hear noises, voices and conversations. Among them were the Rector and Vice-Chancellor of the University of the Free State (UFS), Prof. Jonathan Jansen, and the acting dean of the Faculty of Heath Sciences at the UFS, Prof. Gert van Zyl.

“I can hear my own voice! I haven’t heard it for a long time. My wish is that every deaf child can get something like this,” she said while prodding Prof. Jansen to speak so that she can hear his voice.

Magteld is working at the university's Centre for Health Systems Research and Development and was deaf since birth. She lost her last bit of hearing due to meningitis last year. Her hearing aids could then not assist her to communicate and a cochlear implant was the only option.

A donation by the Austrian company MedEl made the implant possible. Prof. André Claassen, Head of the Department of Otorhinolaryngology at the UFS, says MedEl was also instrumental in the establishment of the implant programme at the Universitas Hospital and sponsored the first five implants at a total cost of R1 million.

Prof. Claassen says 27 implants have already been done here, but it came to an abrupt halt due to a lack of funds. Strong hearing aids are expensive and cochlear implants are even more expensive at R200 000 each. People with hearing disabilities must be identified at an early age as the brain’s ability to learn sound and voice diminishes after the age of three.
