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.

Getting out of the dark
2015-06-10

 

ESKOM is making daily announcements on the status of the power grid.

Anton Calitz, Electrical Engineer at University Estates, is in continuous contact with Eskom and Centlec in an effort to stay abreast of load shedding.

According to Anton, Eskom has recently - the week of 20 April - been focusing on the evening peak, and has announced STAGE 1 load shedding from 17:00-22:00; thus, the Bloemfontein Campus should be able to continue business as usual during the day, except for Thursdays from 18:00 and, possibly, Fridays from 17:00.

Where can I get more information about load shedding stages?

Apart from Eskom’s webpage, staff can also visit GRID WATCH. Click on "Search", then under "Schedules". Look for "Mangaung Local Municipality", and select "GROUP 4". Save this location. “This can even be loaded onto your mobile device.”

“The time slots can be seen for a couple of days in advance, to allow us to plan around the possibility of load shedding in our daily lives,” said Anton.

Please note: ESKOM can change the STAGE level at any time. Therefore, keep an eye on GRID WATCH and News24.

View the typical seven-day planner for the Bloemfontein Campus (Group 4), which indicates the STAGE 2 and 3 possibilities. Take note that, on some days, the STAGE 2 and 3 time slots are the same.

More load shedding tips: Your IT needs

The UFS Data Centre (Computer Room) is fully serviced by a generator facility, and can function without external power supply for a few days.

The generator servicing the UFS data centre does NOT provide power to the outlying facilities. This implies that all digital equipment at gates, booms, and access points will be shut down until the power is restored to these facilities. “We are now, in collaboration with Nico Janse van Rensburg, in a process to install UPS facilities at these points, which will ensure two to three hours of power supply at these points, even during load shedding,” said Dr Vic Coetzee, Senior Director: ICT Services.

No Wi-Fi will be available, as it is dependent on the power supply to the buildings where it is installed.

All servers are contained in the data centre, and will be kept running by our generators.

How to manage load shedding and your IT needs:

1. Get into the habit of saving your work regularly on computer so that you don’t lose your work/files during load shedding.
2. Back up important data. Keep to a schedule of regular back-up.  Make sure your computer back-ups are safe and recoverable.
3. Keep all electronic devices charged and ready to run on battery power. Keep your cellphone charged: some old-style Telkom landlines will still operate during power outages, but others won't.
4. Remember, when power supply is restored, it sometimes happens that a power surge is sent through the network, which will damage your computer.  Fortunately, laptop computers will not suffer this fate as their power is provided through an external power pack. Often, this power pack will be damaged, but not the laptop itself.
5. It makes good sense to reboot your computer daily, not only in terms of power shedding, but also in terms of updating the drivers, software, etc.
6. Switch off all computers and other electrical equipment at the wall plug overnight and on weekends.
7. Should your IT equipment not switch on after a power outage, log a call with the ICT Services. You can also call them at x2000.
