The expensive and risky nature of designing and manufacturing spacecraft components means that hardware and software must be thoroughly tested and validated before they can be used on real missions. …
Most solar sailing missions utilise semi-rigid boom technology, but this limits the possible size of the sail. Practical large sails may, however, be constructed using flexible booms on a spinning …
One of the Electronic Systems Laboratory’s current areas of research is autonomous systems including autonomous vehicles, robots and drones. This involves developing vehicles that can function completely autonomously, and are …
It is estimated that South Africa uses 38.5GWh/day on water heating with water heating contributing up to 40% of a household’s total electricity usage. It places a considerable burden on …
Brushless doubly fed machines (BDFMs) are gaining research interest globally as they offer a practical and reliable alternative to doubly fed induction generators (DFIGs), especially in remote areas like offshore …
Despite the increased global commitment to renewable energy (RE), developing countries still face several barriers to the diffusion of REs as competitor energy generation technologies. These impediments include technological, regulatory, …
CubeSats are nanosatellites of standardised dimensions based on multiple 10-cm-sided cubes. These satellites play various roles in space including being used for both educational and technology-demonstration purposes. In future, they …
Increased human anthropogenic activities such as shipping, offshore exploration, geophysical seismic surveys and naval sonar operations continuously change the soundscape in oceans. This, in turn, threatens the existence of ocean …
Microwave filters are essential parts of wireless communication systems with modern systems, particularly demanding low-cost filters with good frequency selectivity, wide stopbands, and compact size. Coupled resonator (CR) filters are …
The global drive to ensure a future built on sustainable energy is giving rise to the rapidly increasing penetration of variable renewable energy into modern power grids. This has piqued …
