This paper presents a modular digital-twin framework to compare inner-loop attitude controllers: geometric PD (“PID”), discrete Linear-Quadratic Regulator (LQR), and a move-penalized linear Model Predictive Controller (MPC), for a heavy-lift T30-class quadcopter intended for hydrogen propulsion study. The twin couples 6-DoF rigid-body dynamics, actuator mixing, motor/ESC lag, a bus-level electrica
Across the world, emerging technologies and artificial intelligence (AI) are transforming governance, agriculture, healthcare, and education. However, the widespread adoption of such innovations in Africa is often constrained by socioeconomic, cultural, and infrastructural barriers. This review explores the relationship between AI and Indigenous Knowledge Systems (IKS) as a pathway towards inclusi
Monitoring critical infrastructure (CI) like national power networks in developing countries is hindered by the limited coverage and high cost of traditional data collection methods (e.g., sensors, SCADA), making real-time situational awareness difficult during service disruptions. In contrast, social media platforms like X (formerly Twitter) offer a rich but underutilized source of real-time user
There is an increasing need for affordable water treatment solutions especially in developing countries and natural coagulants as alternatives to conventional chemical coagulants with their attendant environmental and health implications, low effectiveness in low temperatures, high procurement cost, large sludge volumes and pH effects. An experimental study was conducted on efficiency of avocado s
