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.

“I am primarily fascinated in the travelling or movement of images in different spaces and media. By moving images from one medium into another, or posting and reposting them in different urban and virtual spaces, I ask questions about media presence and space.”

According to the late artist Dot Vermeulen, this is what the work for her Master’s degree was about. She was still completing it at the Department of Fine Arts at the University of the Free State (UFS).

Her work, called Posting Presence, is currently on display at the Johannes Stegmann Art Gallery on the Bloemfontein Campus. The exhibition is running from 1-30 October 2015.

Vermeulen was a junior lecturer at the Department of Fine Arts before she passed away in a car accident in April 2015.

According to Angela de Jesus, curator of the UFS Art Galery, the exhibition would have been part of Vermeulen’s final evaluation for her Master’s degree. She was one of South Africa’s most promising young artists, and won the prestigious Sasol New Signatures art competition in 2013.

In the work she had done in Posting Presence, Vermeulen said the spaces represented were derived from areas under bridges in an urban space where the visual messages left, speak of an accumulation of movement.

Exhibition event

An exhibition event was held on Friday 16 October 2015 at the Johannes Stegmann Art Gallery to celebrate Vermeulen’s work.

Janine Allen-Spies
and Prof Suzanne Human, the supervisors of her Master’s degree,spoke about the work to those attending.

Catalogue


De Jesus said a catalogue of Vermeulen’s research for Posting Presence had also been compiled, and would be available at the UFS Sasol Library in order for others to “use her work for further research”.

•    Vermeulen’s work can be seen from 08:30-16:30 daily until 30 October at the Johannes Stegmann Art Gallery on the Bloemfontein Campus.
