Abstract

Traffic congestion in areas with two closely situated traffic lights is a complex issue that is often difficult to resolve. To address this issue, a coordination of timing between the two traffic controllers is proposed. This research conducts an experiment with two traffic controllers at two nearby intersections. The vehicle flow at each intersection is managed by the Agent acting as the traffic controller. The agent where more vehicles arrive is designated as the master agent, while the other agent is designated as the slave agent. A coordination algorithm is developed to synchronize the timing of the traffic controller so that the timing at the slave Agent was adjusted according to vehicle platoon arrivals from the master Agent. By this method, the green phase of the slave agent can be synchronized with the master agent, allowing vehicle platoons arriving from the master agent to immediately receive a green phase at the slave agent. This coordinated traffic control can be implemented with a microcontroller-based system, and vehicle movement can be simulated using Matlab's SimEvents. From the experiment conducted for two intersections located 500 meters apart, this scheme can reduce the average vehicle wait time from 40 seconds to just 9.4 seconds.

Abstract

This paper presents the design and analysis of metasurfaces for surface-based wireless communication systems. Metasurfaces are widely used as reflecting or transmitting surfaces in wireless communications. The reflection phase characteristic of a metasurface plays an important role in determining its operating behavior, namely whether it functions as a reflector or a transmitter. In this work, a comprehensive analysis is conducted to obtain two distinct reflection phase characteristics of metasurface unit cells. The unit cells are analyzed at an operating frequency of 3.5 GHz. It is observed that the unit cell exhibits a reflection phase close to 0° when designed using two rectangular rings, while a reflection phase close to 180° is achieved when the unit cell is modeled as a square ring. In both designs, the unit-cell substrate size is fixed at 16.25 × 16.25 mm². The presented reflection phase characterization provides a clear design guideline for selecting metasurface unit-cell geometries to support reflection and transmission functionalities in future surface-based wireless communication systems.

Abstract

This work focuses on refining the radiation pattern of a dipole antenna by introducing a parasitic element and carefully adjusting its size and position. A dual‑band response emerges when the parasitic element is set to a width of 9 mm. The study explores dimensions of 0.98 Wh, 0.90 Wh, 0.70 Wh, and 0.75 Wh. For the first three cases, the element is placed 9.4 mm away from the dipole antenna. In the 0.75 Wh case, however, the spacing is increased to 11.8 mm, which produces a clear improvement in gain. These results show how subtle changes in geometry and placement can significantly influence antenna performance, offering a straightforward path to achieving dual‑band operation with enhanced radiation characteristics.

Abstract

This study addresses the limitations of existing decentralized e-voting systems, particularly their reliance on public distributed infrastructures, limited real-world deployment feasibility, and lack of comprehensive evaluation. Previous studies have demonstrated the potential of distributed ledger-based voting mechanisms; however, most focus on conceptual designs or small-scale prototypes without detailed performance and usability validation. To address this gap, this research proposes and implements a decentralized e-voting system deployed on a local server infrastructure using distributed ledger technology and automated validation mechanisms for vote integrity. The system is designed to reduce dependency on external networks while maintaining transparency, immutability, and operational efficiency. The system was evaluated through functional testing, performance analysis, and user acceptance testing involving 30 participants in a controlled environment with 20 simulated voters. The results show that the system achieved a functional accuracy of 96% across 25 test scenarios. The average transaction response time ranged between 0.6 and 1.6 seconds, indicating efficient processing under moderate load conditions. However, the evaluation is limited to small-scale simulations and does not include stress testing, large-scale scalability analysis, or advanced security validation. Therefore, the findings demonstrate system feasibility rather than fully validated effectiveness. These results suggest that decentralized e-voting systems deployed on local infrastructures can provide a practical and efficient solution for controlled election environments, while further research is required to evaluate scalability, security robustness, and real-world deployment readiness.
