Ahmad Fauzi Othman — 2025-07-25

Ensuring the reliability of power distribution to customers is a challenge for the Distribution Network. It faces various issues such as the need for stable and resilient supply, increasing power costs, support for demand growth, environmental sustainability and the advancement of distributed generating technologies. Additionally, the implementation of the Incentive Based Regulation (IBR) and the reform of the energy market require greater efficiency and innovative products and services. The use of smart and digital technology allows utilities to involve users more actively, but it also demands new network design requirements [1]. Distribution networks used to distribute power from the transmission network to energy customers [2]. Distribution network planning (DNP) methodologies have mostly focused on finding the appropriate locations and sizes for system parts including substations, feeders, transformers, circuit breakers and capacitors to meet the expanding load and ensure power supply reliability. DNP often reduces investment, operating and power losses. The planning horizon predicts load demand for the classic DNP situation, where DG units are negative loads [3]. This study introduces meta-heuristic techniques to optimize the reconfiguration of the distribution system and the installation of DG units for reducing power losses and enhancing voltage profiles. The techniques are based on Modified Lightning Search Algorithm (MLSA) and tested on a 145-bus distribution system model with solar DGs and load profile.

Ili Nadhirah Ibrahim — 2025-07-25

Coastal ecosystems like mangroves, the littoral zone or estuaries play a significant role in maintaining the health and functionality of marine food chains by protecting and securing local rivers from water pollution and sediment delivery. Nevertheless, the coastal regions on the West Coast of Malaysia, particularly in Johor which includes Pantai Perpat (sandy-muddy beach) have undergone notable changes in mangrove vegetation due to the occurrence of excessive suspended sediment that could contribute to the fragmentation of mangrove trees. Thus, this study aims to exert the influence of suspended sediment on mangrove characteristics in Pantai Perpat, Johor. The study area has been divided into two (2) separate zones (Zone A and Zone B). The data in determining suspended solid and physical characteristics has been collected through laboratory tests and primary sources. Then, the data were analysed by using some statistical methods to achieve the objectives of the study. The result of suspended sediment analysis shows the relationship between turbidity and total suspended solids (TSS) in Zone A is higher compared to Zone B. It shows, that the higher the turbidity reading, the higher the TSS levels, thus weakening the soil condition at the location. Moreover, the result illustrates the relationship between TSS and physical characteristics of mangrove trees (diameter of breast height (DBH) and leaf size) and turbidity against physical characteristics: Zone A recorded significantly higher compared to Zone B. It proves, that the higher the TSS levels and turbidity reading, the lower the DBH and leaf size reading. It shows that suspended sediment influences the mangrove characteristics. Therefore, the study aims to exert the influence of the suspended sediment on mangrove characteristics in Pantai Perpat, Johor has achieved. Through this study, a better understanding of suspended sediment dynamics in coastal areas has been completed as well as providing essential information for conservation practices and future planning.

Khalid Fahad Alotaibi — 2025-07-25

To improve interoperability between various digital components and maximize workflow effectiveness in a collaborative setting, a novel platform for the field of digital dentistry was developed. This platform facilitates interoperability and collaboration management by implementing the DICOM standard, thereby enhancing integration and coordination among various stakeholders. This platform has some limitations, and it is not enough to cover most of digital dentistry in dental practice. So, this study aims to cover this gap and the limitations of this platform and process of production in digital dentistry practice. This paper reviews peer-reviewed literature to analyze elements that impact the process of digital dentistry and critically examines an array of technologies and practices to unveil the underlying technologies in the digital dentistry workflow. The study found the absence of many workstations and one modality in the previous platform, as well as the absence of the integration of all dental workflow phases and the absence of the application layer. So, we proposed a novel system that covers most of the digital dentistry in dental practice with the process of production. The new novel platform added one modality, which is the facial scanner, and three workstations, including orthodontic alignment, Digital Design Smile (DSD), and guided endodontic planning. Also, the new system takes into account the integration of all dental workflow phases and the application layer, which was not part of the old platform, as well as the integration of different intelligently guided software to diagnose and suggest treatment.
