    Child tracking system using smartphone
    (Institute of Advanced Engineering and Science, 2023) Taha, Taha A.; Hussain, Abadal-Salam T.; Desa, Hazry; Taha, Faris Hassan; Bektaş, Yasin
    The number of missing children and kidnapping is on the rise in recent years. Every parent wills definitely going through an agonizing experience to have their children missing. Therefore, there are many safety measurements to prevent this incident from happening. The help of modern technologies is one of the ways to reduce children missing and kidnapping. A child can be tracked by using the global positioning system (GPS) and global system for mobile communication (GSM) technology. Advanced child monitoring systems are expensive. Not all families have the same living standards. For this purpose, a low-cost child tracking system is proposed in this study. The implementation of the proposed approach is reported in real-time.

    Enhanced Total Harmonic Distortion Optimization in Cascaded H-Bridge Multilevel Inverters Using the Dwarf Mongoose Optimization Algorithm
    (Department of Agribusiness, Universitas Muhammadiyah Yogyakarta, 2024) Salih, Sinan Q.; Mejbel, Basim Ghalib; Ahmad, B.A.; Taha, Taha A.; Bektaş, Yasin; Aldabbagh, Mohammed M.; Hussain, Abadal-Salam T.; Hashim, Abdulghafor Mohammed; Veena, B.S.
    Total harmonic distortion (THD) is one of the most essential parameters that define the operational efficiency and power quality in electrical systems applied to solutions like cascaded H-bridge multilevel inverters (CHB-MLI). The reduction of THD is crucial due to the fact that improving the system’s power quality and minimizing the losses are key for performance improvement. The purpose of this work is to introduce a new DMO-based approach to optimize the THD of the output voltage in a three-phase nine-level CHB-MLI. The proposed DMO algorithm was also subjected to intense comparison with two benchmark optimization techniques, namely Genetic Algorithm and Particle Swarm Optimization with regards to three parameters, namely convergence rate, stability, and optimization accuracy. A series of MATLAB simulations were run to afford the evaluation of each algorithm under a modulation index of between 0.1 and 1.0. The outcome of the experiment amply proves that in comparison with THD minimization for the given OP, the DMO algorithm was significantly superior to both RSA-based GA and PSO algorithms in their ability to yield higher accuracy while requiring lesser computational time. Consequently, this work could expand the application of the DMO algorithm as a reliable and effective means of enhancing THD in CHB-MLIs as well as advancing the overall quality of power systems in different electrical power networks.

    Real Time Faults Transformer Protection System by Using Integrated Microcontroller
    (Institute of Electrical and Electronics Engineers Inc., 2023) Taha, Taha A.; Bektaş, Yasin; Mahmood, Noof T.; Hussain, Abadal-Salam T.; Ahmed, Ömer K.
    Fault protection is a crucial aspect of power systems, particularly in cases where faults occurring in distribution transformers can have severe implications for customers. However, it is not feasible to equip every distribution transformer with a monitoring system due to the high installation costs and the complexities associated with integrating them into the existing communication network. This study addresses this challenge by modeling the distribution network as a simplified single-phase electrical system and developing a controller that utilizes a PIC18F458 microcontroller. The primary objective of this controller is to provide both protection and onsite monitoring capabilities. Through simulation results, it has been demonstrated that the protection system, which is based on the PIC microcontroller, effectively safeguards against faults such as over-current, overvoltage, and under-voltage. This successful outcome highlights the ability of the developed system to mitigate potential hazards and ensure the reliability of the distribution transformer, benefiting the customers it serves.
