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.

Purgatory is a temporary condition of torment or suffering. This is the central thread of the renowned artist’s exhibition, Purgatorium, at the University of the Free State (UFS). Pauline Gutter’s exhibition was opened by Harry Siertsema on 9 March 2016 at the Stegmann Gallery on the Bloemfontein Campus.

The artist, who grew up on a farm in the Free State, is influenced by animals and farm life. “My work is on many levels a metaphorical representation of the violence of current South Africa. Some people want to move away from stigma, others adopt hysteria. The impressive yet vulnerable bulk of the bulls depicted in uncomfortable positions manifests the voiceless and powerless generation of food producers in their daily struggles for survival,” she wrote in the catalogue of the exhibition.

Prof Dirk van den Berg of the UFS Department of History of Art and Image Studies wrote an essay about the exhibition, in which he captures the lived endurance of stress and suffering which Pauline Gutter depicts vividly in Purgatorium.

“The paintings, drawings, and prints in this exhibition have, in various ways, the effect of disseminating the basic tenor of the weaning metaphor of struggle for survival into the farming domains of the land, its creatures, and its people,” said Prof van den Berg.

Art student, Thamsanqa Malgas, was very impressed with the exhibition, saying that it was a fascinating collection, and a must-see for art lovers. The exhibition closed on 1 April 2016.
