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.

University Estates at the University of the Free State (UFS) were recently awarded for their amazing initiative to install and operate photovoltaic (PV) and greywater systems on all three of its campuses. They were awarded by the Higher Education Facilities Management Association of Southern Africa (HEFMA), an association of facilities managers operating in the higher-education sector in the Southern African region. All universities and universities of technology in the country form part of this association, which promotes excellence in the planning, construction, maintenance, operations, and administration of educational facilities.

Nico van Rensburg, Senior Director of University Estates, says, “I want to thank HEFMA for this amazing award which motivates for much more and also opens up the doors for so many more opportunities.”

Solar and greywater systems installed at various buildings

In December 2016, 26 solar-driven LED street-light poles and a greywater system were installed at the Legae Residence on the South Campus. Greywater is made up of bath, shower, and bathroom sink water. The water is reused for toilet flushing, as well as for irrigation purposes.

On the Bloemfontein and Qwaqwa Campuses, the computer laboratories as well as the Thakaneng Bridge Student Centre and the expected Afromontane Research Centre have freestanding solar solutions mounted on their roofs. These systems are designed to operate independently of the power grid (Eskom) during sunlight hours when the PV solar panels are heated by the sun.

Teamwork equals ground-breaking results

“This was truly a team effort with a variety of role players who contributed,” says Van Rensburg. He believes that higher education can do more to make use of other environmentally sustainable initiatives, and to go beyond just erecting and renovating buildings.

The UFS executive management is also extremely proud of the team that were involved in the project. Prof Nicky Morgan, former Vice-Rector: Operations, says, “It’s been extraordinary what we could achieve at all three campuses with such a small team.” Nadeem Gafieldien, Director: Property Services at Stellenbosch University, showered the UFS with praise. “This is truly ground-breaking for Higher Education (HE) and you are truly leaders in these renewable energy projects in the HE sector.” He says we need to demonstrate to other institutions in the HE sector that this is the future and that it makes the institutions both environmentally and financially sustainable.
