There is always a need to analyze current signals generated by various DC–DC converters. For example, to determine the current stress experienced by semiconductor devices and to evaluate active and reactive power consumption ...

Despite low electricity access rates and weakened electricity sector governance under the pressure of population growth, modes of access to electricity in Lubumbashi vary spatially and in their typologies. However, to ...

The continued commissioning of DC microgrids in an effort to achieve net-zero carbon levels in the atmosphere demands the large-scale deployment of converters to make the power from renewable energy sources, such as solar ...

Spin-scan tomographic scanning imagers utilise a reticle with a fixed number of thin slits and nutating optics, and have produced images and video at both infrared and optical wavelengths. However, the fixed nature of ...

A novel Bayesian framework is proposed, which explicitly relates the homography of one video frame to the next through an affine transformation while explicitly modelling keypoint uncertainty. The literature has previously ...

A model predictive controller was implemented at the flash drying unit of the Anglo American Platinum Polokwane smelter. The controller uses a mix of standard model predictive control technology and dynamic control limits ...

In recent years, low-power wide area networks (LPWANs), particularly Long-Range Wide Area Network (LoRaWAN) technology, are increasingly being adopted into large-scale Internet of Things (IoT) applications thanks to having ...

This research work presents the tri-level optimization framework for the optimal scheduling of grid-connected and autonomous microgrids to diminish power losses and maximize loadability. Since the network's voltage profile ...

The adoption of sustainable hybrid power systems (SHPSs) is witnessing a significant surge among electricity consumers worldwide, which is largely driven by the unexpected geopolitical shock experienced by several European ...

In this issue, we talk with Ian Craig and Derik le Roux about the activities of the Control Systems Group in the Department of Electrical, Electronic and Computer Engineering (DEECE) at the University of Pretoria (UP), ...
