The Solar Tracker has been developed at the Cape Peninsula University of Technology. It is an efficient mechanism for positioning a solar collector to track the sun. This device is adept to intermittent adjustment of the position of a solar energy collection surface, ensuring that the surface

In a COVID-context there is a necessity for social distancing. Consequently, managers of public spaces or institutions may be tasked with the enforcement or monitoring of this requirement. A result is that the real-time tracking of pedestrian movement in public spaces has become a growing reality
The inverse Class-F power amplifier (PA) comprises an appropriately biased GaN active device, input matching network, and output wave-shaping and matching network. The novel design of the wave-shaping and output matching network ensures minimal overlap of the drain voltage and current waveforms, and
