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.

Is Al-Qaeda operating in South Africa?
2014-09-29

 
Our Department of Political Studies and Governance recently hosted a seminar with investigative journalist De Wet Potgieter – author of the book, ‘Black Widow White Widow’.During the seminar, Potgieter reflected on the research he has conducted for the book, revealing the unsettling presence of Al-Qaeda in South Africa.

The ‘White Widow’ in the book’s title refers to Samantha Lewthwaite, a British woman who was found in South Africa with a fraudulent passport. She was later linked to the Westgate shopping mall attack which took place in Nairobi, Kenya on 21 September 2013. In this mass shooting at least 67 people died and over 175 people were wounded. The Islamist group al-Shabaab – which is also linked to Al-Qaeda – claimed responsibility for the incident.

In contrast, the ‘Black Widow’ is the disclosed identity of an Afrikaans-speaking self-styled spy, who after being widowed became a counter-terrorist operative.

Potgieter’s book divulges details of Al-Qaeda paramilitary and urban warfare training on a secluded farm in the Little Karoo and reveals details of the support they receive from various local extremist groups. Potgieter’s investigation spans across two years and suggests possible future attacks from, or on, South African soil.

“South Africa plays a role in the bigger picture for Al-Qaeda Islamic terrorism,” Potgieter said. “For instance, the Navy Seal team who killed Bin Laden found reports pointing to active Al-Qaeda/Islamist presence in South Africa. South Africans need to know we are under siege by a small, well-trained Al Qaeda terrorist cell. Yet, operations – of which I know, but cannot disclose much – are also underway to contain these matters,” Potgieter added.

Potgieter’s sources suggest that Al-Qaeda has been active in South Africa since the 2010 FIFA World Cup already. The South African government seems to turn a blind eye, though, despite CIA and MI6 requests and enquiries on the matter.
