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.

Renewable energy systems an economical investment for the UFS

Renewable energy systems are said to be very expensive to implement initially, but in the long run they provide high economic returns.

With their decision to install renewable energy, the University of the Free State Department of Facilities Planning has now also adopted this innovative technology. They have chosen less capital-intensive solar power-generating options to generate electricity in various buildings and parking areas on all three UFS campuses.

“As per the UFS Energy Management Policy, all designs incorporate efficient, renewable energy sources varying from LED lights to solar power,” says Anton Calitz, Electrical Engineer in University Estates’ Department of Facilities Management.

South Campus taking the lead in renewable energy usage
In December 2016, a total of 26 solar-driven LED street-light poles were installed at the recently built Legae Residence’s parking area and the perimeter security area on the South Campus. This low-maintenance system improves security after dark and is independent of the national power supply, which is an important advantage during power outages. With no requirements for major earthworks and cable setting, operational costs are reduced.

The recently built infrastructure also takes pride in being the first to have a greywater system installed.  This system will also be installed at three other residences on the Bloemfontein Campus in 2017. Greywater is made up of bath, shower, and bathroom sink water. The water is reused for toilet flushing, as well as for irrigation purposes.

Various UFS electrical operations to depend on solar power
On the Bloemfontein and Qwaqwa Campuses, the computer laboratories as well as the Thakaneng Bridge Student Centre and the projected Afromontane Research Centre will be equipped with freestanding roof solar solutions during 2017. These systems are designed to operate independently of the power grid (Eskom).

The systems only operate during sunlight hours when the PV solar panels are heated by the sun, making them suitable for operations such as ventilation fans, water pumps, and small circulation pumps for solar thermal water-heating systems.
