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

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
It is well known that many beneficial microbiological processes, especially bacterial processes, take place naturally and each different process involves the activity of different species/genera of bacteria. The speed of catalysis in the relevant bacteria is, however, also dependent on prevailing
