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.

Department of Agricultural Economics and agri-business join forces
2009-12-01

The Department of Agricultural Economics at the University of the Free State (UFS) launched a bursary programme to support students studying Agricultural Economics during its recent half-centenary celebrations.

More than half a million Rands were collected from various agri-businesses at this prestigious event in order to support approximately 16 Agricultural Economics students from 2010 onwards.

“The Department is proud of the past 50 years’ training of students for agriculture in the fields of research, governance, banking and the agri-business environment and we have launched the bursary programme in order to position the University closer to agri-businesses,” said Prof. Johan Willemse, Departmental Chairperson of the Department of Agricultural Economics at the UFS.

The agri-businesses, who will act as sponsors, also benefit from the project, because they are afforded the opportunity to identify promising Agricultural Economics students as potential employees and to expose them to the activities of the businesses by means of holiday work. Upon completion of his/her studies, the student will already be fairly familiar with the circumstances of the specific agri-business and loyalty towards the business will already have been established.

Students who major in Agricultural Economics may apply for the bursary programme.

Agri-businesses that have already agreed to act as sponsors are Omnia Fertilizer, Pioneer Foods Pty, Suid-Wes Koöperasie Beperk, Corporate Guarantee, GWK Beperk (Griekwaland-Wes Koöperasie), VKB (Vrystaat Koöperasie Beperk), the National Woolgrowers Association and NWK Beperk (Noord-Wes Koöperasie).
