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.

Medical screening tests can help detect health risks at an early stage
2013-09-09

09 September 2013

It is once again time for the annual medical screening tests done by the Centre for Health and Wellness, which helps staff at the University of the Free State to watch their health.

All staff members are invited to participate and to find out how healthy they really are.

Dr Anette Prins, Deputy Director of the Centre for Health and Wellness, says their aim this year is to get every staff member to go for a checkup.

“For this reason, the tests will be done on different days and in different buildings. In this way, we take the test to the staff and they don’t have to come to a particular point as was done in the past.”
According to Discovery Health’s Healthy Company Index for 2013, in which the UFS also participated, about half of South African employees suffer from four or more health risk factors (blood pressure, obesity). The worst is that almost 70% of employees in this group believe that they are both fit and healthy. Fifty-three percent of those employees do not go for the essential preventative health checkups.

However, this picture may change as a result of the annual medical screening tests for staff of the UFS, because risk factors such as high blood pressure, cholesterol and high blood sugar levels can be detected at an early stage.

The tests take about 30 minutes per person and include a physical test, as well as an electronic questionnaire. The entire process is very confidential.

This year there are also prizes up for grabs, such as a Nexa Polaris 7.0 tablet and travel bags, during each session.
