How can a superconducting qubit design move from chip geometry to a computable model of quantum behaviour?

In his engineering research project, Reece Bird unders supervision of Professor Coenrad Fourie, developed a software toolchain that automates this process. Starting with verified designs from the SQuADDS database, the program recreates each layout, prepares and runs InductEx and PALACE simulations, constructs Hamiltonians using two independent methods, and generates a detailed report.

Tests on five qubit-cavity designs found that the capacitances used in the calculations were within 10% of established reference values. PALACE eigenmode frequencies were within 7% of the reference simulations. Across the principal quantum parameters, about 85% of results were within 20%, and many were closer.

The comparison also quantified an important trade-off. The Lumped Oscillator Model averaged 20.6 minutes, while the more general Energy Participation Ratio method averaged 92.6 minutes and produced more consistent results. Two layouts also showed why direct eigenmode results remain preferable for cavity frequency under some geometric conditions.

In celebration of Women’s Month, some of the women who continually support the Department of Electrical and Electronic Engineering were treated to a special lunch in recognition of their kindness, dedication and the important work they do. 🌸

On Wednesday, 26 August, the group gathered at The Pottery in Stellenbosch for lunch and pottery painting, while taking time to connect and celebrate.

Representing our academic, administrative and technical staff, as well as departmental assistants, these women each play a valuable role in our Department.

Thank you to every woman who contributes her knowledge, skill and dedication to our EE community.

How can a high-altitude UAV regain its position when satellite navigation is disrupted?

In his Electrical and Electronic Engineering research project, William Kevin Morley, under supervision of Professor Rensu Theart, developed a lightweight visual place recognition system that allows an unmanned aerial vehicle to compare its current camera view with a sparse trail of geo-tagged ‘breadcrumbs’ captured earlier in the flight.

On the high-altitude test route, the system used only 26 stored breadcrumbs to accept 1,198 loop closures. Every accepted match identified the best available breadcrumb, while the storage method reduced retained data by 98.91%. A full recognition cycle took about 87.5 milliseconds on the CPUs used for testing.

The research also identified a clear limit. The system accepted no matches over lower, visually repetitive terrain where the outbound and return routes were widely separated. This contrast shows why terrain, viewpoint, sensor quality, and matching thresholds all need to be considered when developing navigation systems for disrupted GNSS conditions.

A final-year mechatronic engineering project at Stellenbosch University’s Faculty of Engineering explored how raw radar reflections can be reconstructed into a two-dimensional image.

Satheesh Bissessur, under the supervision of Mr Lanche Grootboom, developed a MATLAB algorithm that processes measurements recorded while targets rotate through 360 degrees in front of a radar system. The project combined background subtraction, windowing, range alignment, back projection, and minimum-entropy focusing.

The final algorithm located both single and multiple targets and achieved a measured resolution of 1.65 cm in the distance and cross-range directions. It also showed how reducing the number of viewing angles affects image focus and spatial detail.

The project provides a foundation for future work on more complex target shapes, improved positional accuracy, and other radar-imaging applications.

When radio signals don't behave as planned at the Square Kilometre Array site in South Africa, the cost isn't just technical, it's time and money spent on redesign.

A final-year engineering project at Stellenbosch University by Me Nikita van Rooi, supervised by Prof Riaan Wolhuter, compared two radio propagation models across 411 site links to understand exactly when and why each model fails.

The result: ITU-R P.526 outperformed Longley-Rice, with 78% accurate predictions versus 68%. Machine learning identified the specific terrain features — clearance ratio, obstacle height, mean elevation — that drive failures in each model.

A practical framework that engineers can use to flag high-risk links before they become costly problems.

How can a target impact be confirmed when visual spotting becomes difficult over long distance?

A final-year mechatronic engineering project at Stellenbosch University explored that question by developing a wireless Target Hit Indicator for steel gong targets.

Built by Dean van Zyl, the prototype combines accelerometer-based impact detection with LoRa radio communication. When the target is struck, the transmitter detects the impact and sends a feedback packet to a handheld receiver with an OLED display.

Field testing showed reliable communication at 1 km, 206.8 ms feedback latency, 100% impact detection accuracy in the test setup, and an estimated battery life of more than 100 hours.

The project brings together sensor selection, PCB design, firmware development, radio testing, and practical prototype validation.

A final-year engineering project at Stellenbosch University explored how a locally hosted Home Energy Management System can help households make better use of solar, battery storage, and outage planning.

Built by Aldrich Opperman, under the supervision of Dr Arnold Rix, the system runs on a Raspberry Pi with a touchscreen dashboard that brings together inverter data, weather forecasts, load-shedding schedules, and smart-switch control.

The project moves past simple monitoring. It predicts household demand, estimates solar generation, and adjusts battery charging and selected loads ahead of outages.

It’s a practical piece of engineering shaped by South Africa’s energy context, and by the day-to-day decisions households face when grid supply is uncertain.

How do you stay in touch when mobile networks are overloaded or unavailable?

A final-year engineering project at Stellenbosch University explored that question by developing a two-part off-grid communication system that pairs a smartphone app with a compact LoRa device.

Built by Gerhard Arnold Hattingh under the supervision of Professor Rensu Theart, the system supports text messaging, location sharing, friend-finding, and low-resolution image transfer without relying on cellular service or Wi-Fi.

Field tests showed reliable two-way communication over roughly 2 km in open terrain, with setup from app launch to first message taking about 39 seconds.

It’s a thoughtful piece of engineering that brings together hardware, software, security, and user-focused design into a single practical system.
