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.

UFS researcher fills void in South African policing history

late nineteenth century South African policing on the

“I used policing on the Witwatersrand as a lens through which to examine aspects relating to state formation within the South African Republic.”

This is how Dr Cornelis Muller, a postdoctoral fellow in the International Studies Group at the University of the Free State (UFS), described his PhD thesis called Policing the Witwatersrand: A history of the South African Republic Police, 1886-1899. The thesis fills an empirical void in the history of settler colonial policing in South Africa.

His research was also featured in the South African Historical Journal, which is published by Routledge. Dr Muller received his PhD from the UFS during the 2016 Winter Graduation ceremonies. He received a scholarship from the university to conduct his three-year research.

Relationship between police and state examined

The study presents itself as an institutional biography in which the relationship between the South African Republic Police (known as the Zarps), the state, and broader society are examined. The period under investigation was a time when political, economic, and social complexities on the Witwatersrand created tension between South Africa and Great Britain.

An important theme throughout the thesis is the relationship between the police, the mining industry, and the so-called Uitlander community. Crime was also an important contributing factor to the complex relationship that developed between the Zarps and the policed in Johannesburg’s formative years.

“Johannesburg was a town under siege by a variety of crimes which ranged from vagrancy, drunkenness, gambling, and prostitution to robbery, murder, and assault,” said Dr Muller.

Archives in South Africa and Great Britain consulted
“My thesis follows a chronological approach in which various themes accounting for the development of the police on the Witwatersrand are highlighted.” Framed within the bureaucratic and administrative functioning of the Zarps, he examined aspects relating to crime, crisis, and conflict between the police and society. The thesis also details the relationship between the police and Johannesburg’s black community.

As with any historical research, it comprised internal and external source criticism and content analyses of a wide range of archival records.

Dr Muller had the opportunity to visit several archives and libraries in South Africa and Great Britain. “Some of the more important archival collections were assessed at the National Archives in Pretoria.” These included the Archive of the State Attorney and the Archive of the Magisterial District of Johannesburg.

“My study thus adds to scholarship that seeks to provide a more nuanced understanding of the South African Republic’s administrative functioning and internal politics in the late nineteenth century,” concluded Dr Muller.
