Kamil Ali Kamil, Ben Sujin — Tue, 30 Sep 2025 00:00:00 +0000

The Wireless Power Transfer (WPT) technology has evolved rapidly as the preferred technology of charging electric vehicles safely, conveniently and easily outdoors since plugging poses certain issues to users and to the vehicles. This paper gives the design and simulation details of an inductive WPT system optimized to be used in EV charging. System architecture Utilizing inductive coupling, the system architecture enables high-efficiency energy transfer across a 20 centimeter air gap, as would exist between a vehicle and ground coils. It is designed with sophisticated coil shape and Litz wire to maintain the resistance low and increase the quality factor of the circuit. Electromagnetic analysis is performed in ANSYS Maxwell to calculate system performance and compensation efficiency and load dynamics are calculated by circuit simulation in MATLAB/Simulink. Since a Series-Parallel (SP) topology has been selected in the proposed system, the reactive power loss on the primary side and the robustness of the voltage on the secondary side is kept quite well. The simulation results depict that the power efficiency within the system exceeds 90% at 3.3 kW, thus the system meets performance indicators of typical EV chargers. Moreover, the design considers both thermal and electromagnetic safety, meaning that it conforms to the international regulations of ICNIRP and SAE J2954. Due to the above characteristics, the WPT system presented in this paper can be implemented in the future smart charging networks of electric vehicles.

Sufyan Yakubu, Dr. Beenu Mago — Fri, 03 Oct 2025 00:00:00 +0000

Structural Health Monitoring (SHM) is vital for the protection of urban buildings as more cities become smart. This work suggested an AI-based SHM framework to support the enhanced resilience, safety and upkeep of critical infrastructure. WSNs, edge computing and a deep learning model mixing CNN and LSTM units are part of the framework. As a result, architects can track any obvious concerns in structure in near real-time with vibration and strain sensors placed on both urban bridges and high-rise buildings. The model uses data collected in simulations and the real world to discover errors in structures, ensuring an accuracy of over 96%. Moreover, when edge-based processing is used, both latency and bandwidth needs are minimized, making the system capable of handling many large-scale deployments. A case study of a bridge in Bangalore indicates that the approach can monitor continuously, detect faults early and warn in advance. The new process is shown to have a 35% lower rate of false positives than theoretical threshold methods. The results emphasize that AI-led SHM systems play a key role in predictive maintenance and strengthening urban infrastructure in these rapidly changing smart urban environments.

Model Predictive Control for Power Quality Enhancement in Grid-Tied Renewable Energy Inverters

The project aims at applying Model Predictive Control (MPC) to increase the power quality of grid-tied inverters connected to photovoltaic (PV) and wind systems. The presence of increased renewable energy on the power grid has led to an increased possibility of occurrence of harmonic distortion, voltage variations and a decline in quick response that may compromise the grid and violate power quality norms such as IEEE 519. Conventional controllers like proportional--integral (PI) and hysteresis control cannot always produce the correct result in a response to system dynamics and various properties of systems. These problems are eliminated in the framework which predicts what will take place in the system and switch the inverter appropriately to minimize a given cost function. With this solution, harmonics rejection and efficient current monitoring as well as rapid adaptation to grid issues and changed demand are realized. Simulation study In MATLAB / Simulink, the comparison of the proposed MPC controller against conventional control methods was achieved through simulation with different irradiance variations and loads being switched on / off. The results state that MPC-based inverter control introduces THD of less than 3%, ensures that the voltage remains in a range of +/- 2 percent of the nominal value and enables quicker transient responses, renovating renewable energy systems more dependable and compliant. Besides, MPC enables safety and control properties that makes it flexible to suit the future needs in smart grids. This method brings a practical solution that highly benefits a power grid to operate normally, provide high power quality and operate effectively with increased renewable energy, promoting the usage of intelligent inverters within the power supply system.

Martin Sankoh, Dr.Andrew Huey Ping Tan — Tue, 30 Sep 2025 00:00:00 +0000

Through the connection between Building Information Modeling (BIM) and Geographic Information Systems (GIS), the planning of smart cities is enhanced since it addresses both the comprehensive information on buildings and coarse spatial data. BIM provides in-depth information on design and building whereas GIS provides the geographic context and considers the environment, therefore, both BIM and GIS will need to be integrated to make intelligent decisions in city development. The paper is a research on how BIM and GIS together can enhance planning of city infrastructure, resource utilization and real-time monitoring in smart cities. It takes into account the involvement of modern technology, challenges of communication between various tools, success stories that demonstrate the greater efficiency, sustainability and new quality of citizen participation. It also suggests what ought to be carried out in order to facilitate organizations to operate and share information with one another. Urban planners, with their united powers are able to make the cities more thoughtful, ready and eco-friendly.

Aerospace engineering requires the need to make aircraft lightweight in order to increase efficiency, cargo capacity and overall output. Topology optimization that mathematically steers the process of placing material in a given design space, is useful in arriving at lighter designs that satisfy the needed constraints. It enables the production of more sophisticated parts in the aerospace sector when used with additive manufacturing (AM) that eases the production of complex geometries. The article investigates the possibility of utilizing topology optimization to AM to produce strong yet lightweight aerospace components. An analysis of a bracket of an aircraft is provided to indicate that the weight of the bracket was minimized to a significant extent thus it is more efficient. The new approach according to the research is a big difference in the aerospace design today.

Ts. Dr. Tan Kian Lam (Andrew), Dr. Lim Chen Kim — Tue, 30 Sep 2025 00:00:00 +0000

As 5G is being rapidly deployed, cities are being turned into smart spaces with objects inter-connected to enhance the transportation, energy, healthcare and public safety services provided by the city. Nevertheless, along with the improvement of connections, there are also difficult-to-address cybersecurity issues, primarily caused by the greater susceptibility of critical infrastructures to attacks. In this case, we talk about cybersecurity challenges that 5G hastens in smart cities as the possible issues emerging due to network slicing, edge computing usage or a large number of IoT devices within a single location. The paper examines various threats including data breaches, denial-of-service attacks and problems that could encounter the 5G network with keen attention. It also examines the steps that are currently in place to curb these risks e.g. tight security policies, new laws and collaboration between relevant teams. The paper next proposes the practices that may strengthen the cybersecurity of 5G smart cities and defend critical assets against emerging cyberthreats.
