The research focuses on the foundational elements of the Internet of Things (IoT) infrastructure and its applications in smart buildings, smart parking, and smart cities. Wireless Sensor Networks (WSNs) play a critical role in enabling these applications. However, due to their low battery energy, WSN nodes are severely constrained, limiting their operation to a few […]
Conventional direct torque control (DTC) improves the dynamic performance of the five-phase induction machine (FPIM). Nevertheless, it suffers from significant drawbacks of high stator flux and electromagnetic torque ripples. Moreover, the DTC technique relies on an open-loop estimator for accurate stator flux module and position knowledge. However, this method is subjected to substandard performance, mainly […]
Large scale requirement engineering needs automated precise and efficient capability modeling and analyzing methods formally to interoperate with the evolving and goal driven requirements.

Sulfur hexafluoride (SF6) is extensively utilised as an essential insulating material in high-voltage industries owing to its outstanding electrical characteristics. However, the use of SF6 gas faces two significant challenges: its substantial impact on global warming and the high toxicity of its breakdown byproducts. This study aims to analyse the breakdown properties of various gas […]
A double-coupled isolated inductor-based high step-down DC-DC converter is proposed in this work. This converter employs two windings on the secondary section of every coupled coil within a single core which enhances the utilization factor of the core. As the primary section voltage of the second coil is reduced, the leakage inductance and turn ratio […]
Jet engines consume a lot of power at start time which makes necessary to use a ground power supply unit (GPU). The GPU must provide the aircraft’s demanded power at the start point only. One of the most important factors in supplying the required power for jet engines is to provide the necessary quality for […]
Due to economic and environmental constraints, power systems are operating near critical limits as load demand keeps growing rapidly. To improve the transfer capability, system losses, stability, and maximum loading parameters of electrical power systems, Flexible Alternating Current Transmission Systems (FACTS) devices can be used to control power flow and regulate bus voltage. This research […]
Providing reliable and sufficient power to the client is essential. Power quality is determined by the consistency of frequency and tie-line power between control regions. Thus, the importance of Load Frequency Control in an electrical network cannot be overstated. In this work, a PID controller using the Grey Wolf Optimization algorithm is employed to help […]
