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.

UFS takes the lead in solar heating in the Free State

The University of the Free State (UFS) took a further step in reducing its carbon footprint and its dependency on coal fired electricity with the installation of a solar heating system at one of its residences. The contractor handed the system over to the UFS on Wednesday, 2 June 2010.

The system installed at the Vergeet-my-nie Residence is the first commercial solar water heating project in both Bloemfontein and at the UFS. It is estimated that it will provide in 70% of the residence’s energy needs and save approximately R101 000 per annum in electricity cost. The project was completed at a cost of R2,4 million.

More residences at the UFS will be refurbished with solar systems as the existing heating systems in the rest of the twenty residences are due for replacement.

The energy crisis of 2008, and the challenges and necessity to reduce the use of electricity, sparked the initiative around the installation of solar heating systems at the UFS. The UFS is the second largest energy user in Bloemfontein.

Mr Nico Janse van Rensburg, Manager: Physical Planning at the UFS, says the management of the UFS saw an opportunity in the crisis and pro-actively embarked to become a market leader. Solar heating would not only alleviate the electricity problem of South Africa, but will impact the ever increasing electricity bill of the UFS.

“Protecting the environment and being on the cutting edge of technology are core issues to the UFS,” says Janse van Rensburg. “We are an educational institution and take pride in practicing what we preach.”
