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.

Research at the UFS on the acceptability and modern use of earth building in newly settled urban areas can help the poorest of the poor to acquire hou
2003-08-26

The University of the Free State and the Technische Universiteit van Eindhoven in the Netherlands received a research bursary of R316 000 from SANPAD (South African Netherlands Research Programme on Alternatives in Development).

The aim of the research is to determine the public acceptability of sustainable, high quality, earth constructed public and private buildings as an alternative to the conventional way of building with bricks and steel.

“European countries like the Netherlands are far advanced with studies in earth construction and this is why the partnership was formed with the Technische Universiteit van Eindhoven,” says Prof Das Steÿn, Head of Urban and Regional Planning at the UFS and project leader.

Although research regarding mapping, typology and availability of natural and local resources has been done on a national level, little research has been done on the acceptability and the modern use of earth building in newly settled urban areas.

“South Africa has a large housing shortage and traditional methods such as earth building techniques are not used in urban informal housing. Preference is given to corrugated iron sheets and plastic,” says Prof Steÿn.

The use of upgraded earth construction might be more sustainable as far as the environment and the economy is concerned. “If we can make a breakthrough in the development and propagating of these methods it will help the poorest of the poor to acquire housing of a better quality.”

The research team from the UFS consists of Prof Steÿn, Ms Petria Jooste-Smit, Head of the Unit for Earth Construction in the Department of Architecture and Mr Gerhard Bosman of the Department of Architecture.
