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.

Machinery and equipment to the value of R6 million acquired by UFS Instrumentation Division

At an information session held on the Bloemfontein Campus, the Instrumentation Division in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) introduced its new Computer Numeral Control (CNC) machines to the value of R6 million.

Initially, the primary aim of the Instrumentation workshop was to design, produce, and maintain special research equipment which is unavailable on the market, mainly for academic departments. The small-scale production focused on producing support material and equipment for research work.

However, with new equipment and machinery the Division now also can deliver a service to corporate companies and external associates.
 
The CNC machines include a 5-axis Vertical Machining Centre from Haas imported from America. This is one of only four in South Africa, with two in Johannesburg and one in Cape Town.  The lathe makes it possible to produce sophisticated parts, which were previously cumbersome and difficult to make. The machines also cover a wide spectrum in the mechanical field such as the the FLOW Water Jet, which cuts a wide variety of material ranging from titanium to wood without utilising heat, thus saving electricity. This makes it possible to cut a wide variety of materials.

With the new machinery now available, the Instrumentation Division is able to perform high quality and quantity production with precision.

“The advantage of the machinery is that it stimulates production, and is much faster and more accurate than the conventional way of doing things,” said Pieter Botes, Head of the Division.

Botes explained that, by having students and professional artisans at the university design and manufacture equipment, costs are reduced when compared with the expensive nature of equipment and tools found in the market. In addition, “the machines broaden the scope of research conducted” said Botes. The technical dynamics of the machinery advances the scientific knowledge needed to operate it, so bridging the gap between theory and practice.

The Central University of Technology, Signs Division Bloemfontein, Product Development Technology Station (PDTS), Maizey’s, and Knottco Truckparts are some of the university’s trade partners.

The workshop collaborates with the Chemistry, Physics, Microbiology, Botany, Agriculture, and Electronics departments, as well as the Institute of Groundwater Studies at the UFS, and others. These departments receive services in the form of pipette stands, containers for test tubes, bottles, laboratory trolleys, stands for cadavers for Anatomy, pump repairs, stainless steel bailers, filaments, and heaters.

The Instrumentation Division is, therefore, a vital support unit for the Faculty of Natural and Agricultural Sciences as well as the university at large.
