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.

Cedric Nunn’s latest photographic exhibition, Unsettled: One Hundred Years War of Resistance by Xhosa Against Boer and British, opened on 25 May 2016 at the Johannes Stegmann Art Gallery of University of the Free State, and will run until 17 June 2016. Since 2014, the exhibition has travelled through South Africa and the USA as well as Germany.

The photographer, documentary film-maker, and artist’s photographic journey was launched in the early 1980s in Durban. In 2011, he won the first FNB Joburg Art Fair Award.

Narratives of the victors and the vanquished

Unsettled deals with the nine wars that Xhosa people were subjected to between 1779 and 1879 in their fight against Afrikaner and British colonial settler forces. Nunn’s art seeks to instigate social change, and highlight lesser-seen aspects of society.

The work emanated from his awareness of a notable gap in the telling of this piece of South African history, as well as the fact that, to date, little has been done to memorialise these acts of colonial aggression and Xhosa resistance. He decided to document the land where these struggles took place.

“Through revisiting this painful past in the contemporary scenes of today, this work attempts to place the present in its factual context of dispossession and conquest,” said Nunn.

Unsettled
forms the first component of what will be a trilogy. The next component will address the legacy of colonial dispossession through “bringing ‘the first inhabitants’ back into the picture by giving a select number of self-describing Khoi, Griqua, and San or Bushmen a contemporary face and presence”. The final component will look at slavery.
