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

Certain liquids, such as wine, are sensitive to contact with oxygen and may be degraded by oxidation, so winemakers usually take steps to limit or entirely prevent oxygen from contacting the wine. For example, inert gases may be used to displace oxygen. In reductive winemaking processes, oxygen is
