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.

Prof Johan Spies learns about much more than genetics in Argentina
2014-04-23


People who attended the course enjoyed Argentina and its traditions very much.

Prof Johan Spies from the Department of Genetics visited Argentina, where he and Dr Carlos Acuna (Universidad Nacional del Nordeste, Corrientes, Argentina) presented a course for doctoral students and staff of Cerzos-Conicet Bahia Blanca (something like the equivalent of South Africa’s NRF) and Universidad Nacional del Sur, Bahia Blanca. Prof Spies presented chromosomal evolution and its effect on fertility, while Dr Acuna took care of apomixis.

Bahia Blanca is a city with a population of almost the same as that of Bloemfontein. The city lies at the mouth of the Naposta River, which almost forms a delta where it flows into the sea. Bahia Blanca (white bay) derives its name from the salt deposits that lends a white colour to the beaches.

The people are very friendly and one soon learns to extend a long arm in greeting. Otherwise you are stuck with an ‘Ola’ while men and women alike will grab even a complete stranger to plant a kiss on your cheek. For people who places great value on personal space, this friendly gesture is not always as welcome!

Barbeque is a choice dish and is usually in the form of beef rib. “It was great (especially if you shut your eyes and ignore the scrumptious fat and future heart attacks)! With the rib they usually had blood sausage and very tasty pork sausage on the grid. Everywhere people are sipping, through a silver straw, their ‘mate’ (pronounce maty), a type of tea made from the leaves and stems of Yerba paraguariensis. It is generally drunk from a special calabash ‘cup’ through a silver straw, which also serves as sift to keep the leaves from your mouth. The calabash is usually passed from one person to another, with each person taking a sip from the brew!  It is even passed around in class!  Another thing in conflict with the upbringing I received from my mother (as is the cup at communion)!,” says Prof Spies.

“My short visit also taught me that the Argentinians are a proud nation that often faced adversity in the past. Nevertheless, they do not try to change their past. Street names even refer to dates from their past when, for example, they were attacked by England (in 1807). Only the almost 30 000 people who disappeared under the military regime, are rarely talked about!,” says Prof Spies.
