The growing ubiquity of Wi-Fi has necessitated the development of small and effective antenna designs, especially microstrip patch antennas. In the Wi-Fi frequency range of 2.4 GHz to 2.4835 GHz, this paper compares the performance of circular and rectangular microstrip patch antennas. The study aims to evaluate their performance regarding radiation characteristics, gain, and bandwidth to help choose antennas for Wi-Fi applications. According to the results, the rectangular patch antenna with a rectangular slot outperforms the circular patch antenna with a rectangular slot regarding return loss, coming in at roughly -37.07 dB. Furthermore, the Voltage Standing Wave Ratio (VSWR)value of the rectangular patch antenna is 1.02, which is higher than that of the circular patch antenna, which is 1.34. The rectangular patch antenna has the most excellent radiation efficiency (64.5%) and offers the broadest bandwidth (about 115 MHz). Engineers and researchers looking to enhance antenna designs for Wi-Fi applications can learn much from this study by considering variables like radiation efficiency, bandwidth, VSWR, and return loss. © 2023 IEEE.

Traditional broadband solutions are often economically and technically infeasible in rural regions due to sparse populations, high infrastructure costs, and energy inefficiencies. This makes rural broadband access a critical challenge, particularly in developing countries where socio-economic disparities and geographical barriers exacerbate the digital divide. This paper proposes an innovative cluster-based network architecture to address such challenges by leveraging low-power Customer Premise Equipment (CPE) and underutilized television white space (TVWS) frequencies. The proposed system forms collaborative clusters of CPEs that use distributed beamforming (DBF) for transmitting data to a central Point of Presence (PoP) Base Station. This approach reduces the need for extensive infrastructure and high-power transmissions, offering a cost-effective and energy-efficient solution. A two-tier uplink access protocol is introduced to optimize data transmission, ensuring scalability and reliability as rural populations grow. By addressing the unique challenges of rural connectivity, this study provides a viable pathway for expanding internet access, enabling socio-economic growth, and bridging the digital divide in underserved communities. Key contributions include dynamic clustering algorithms, scalability enhancements, and a comprehensive performance evaluation, offering a transformative model for rural broadband deployment. Simulation results demonstrate that the proposed architecture is up to 20% more energy efficient with significantly improved throughput compared to conventional rural broadband access schemes. © 2025 IEEE.

Unmanned Aerial Vehicle (UAV) networks are increasingly employed in mission-critical applications, demanding efficient and reliable communication protocols to address key challenges such as energy efficiency, collision avoidance, scalability, and Quality of Service (QoS). This paper presents the development of a Long-Distance Ad-Hoc Medium Access Control (MAC) protocol tailored for UAV networks to address such issues. This novel protocol combines hybrid MAC techniques, utilizing Time Division Multiple Access (TDMA) for inter- cluster communication and Code Division Multiple Access (CDMA) for intra-cluster transmissions ensuring resource utility efficiency and high throughput. Key features of the protocol include dynamic power control, proximity-based slot allocation, UAV trajectory sharing, and priority-based scheduling to support real-time data transmissions. Simulation results demonstrate that the protocol has up to 15-20% improved energy efficiency, ensures 100% successful collision resolution, provides scalable solutions for up to 100 nodes, and enhances QoS with a success rate of up to 95% for high-priority traffic. These results highlight the protocol's effectiveness in meeting the demanding requirements of real time communications in UAV networks with potential to support large-scale, energy- efficient, and collision-free communication in dynamic environments. © 2025 IEEE.

Assessing traffic surveillance data is a prevalent utilization of deep learning methodologies. Video processing techniques were employed to develop the system aimed at determining the velocity of vehicles. The analysis of video speed is conducted without the requirement of camera calibration. Frame subtraction and masking techniques are employed to effectively segregate moving vehicles. The suggested system comprises four primary components. Object detection techniques are employed in the initial phase to identify and locate moving vehicles within a given footage. Real-time vehicle recognition leverages the utilization of R-CNN and deep learning techniques. In the subsequent section, algorithms are employed to observe the movement of objects within individual video frames. Optical flow methods are employed in the third segment to ascertain the velocities of the respective vehicles. In the preceding part, the proposed work have utilized image processing techniques in conjunction with deep learning methodologies to accurately decipher the license plates of the automobiles under our surveillance. The experimental evaluation involving the utilization of traffic film demonstrated a system performance of 97% in precisely quantifying speed while achieving a license plate identification accuracy of 95%. The incorporation of state-of-the-art traffic management systems has facilitated the implementation of real-time speed monitoring and license plate reading capabilities. This facilitates the deterrence of automobile theft and the implementation of traffic regulations. Additionally, the methodology has the capability to identify traffic patterns and pinpoint regions of congestion, thus assisting in the effective management of traffic. © 2023 IEEE.

On Microgrid Protection Using Synchronized Phasors

On Microgrid Protection Using Synchronized Phasors

引用

IEEE Texas Power and Energy Conference (TPEC)

作者： Jorge I. Cisneros-Saldana Miroslav M. Begovic Department of Electrical and Computer Engineering Texas A&M University College Station USA

This paper proposes a reliable technique to leverage current measurements while using phasor measurement units (PMUs). The estimation of Phasors typically relies on the Discrete Fourier Transform (DFT) algorithm, to overcome its drawbacks, the Recursive-Discrete Fourier Transform (R-DFT) algorithm could be used. This study synchronizes off-nominal grid frequen-cies in phase current measurements, a common DFT analysis drawback faced in PMUs implemented in islanded microgrids, amidst voltage-based phase measurements. The proposed method uses all three-phase voltage Phasor measurements to track fun-damental frequency changes and consequently adjust all three-phase current Phasor measurements individually. This approach supports per-phase analysis for its applicability in both balanced and unbalanced conditions in microgrid operation. It offers insights into individual phase behaviors and equips the protection system to detect and mitigate symmetrical and asymmetrical disturbances. The simulation outcomes vividly show the efficacy of our method in reducing errors arising from off-nominal fundamental frequency variations. The results underscore the method's ability to differentiate between short circuit-type faults and typical tapped loads within the protection zone. This innovative approach has the potential to improve the performance of immediate microgrid protection schemes and ensure reliable operation within them. Based on our results, per-phase analysis has shown to be a more versatile and comprehensive protection strategy in scenarios where microgrids face unbalanced and asymmetrical disturbances, as opposed to a more traditional symmetrical component fault analysis because of the special nature of inverter response under abnormal conditions.

The studies in this research are focused on the mix of homomorphic encryption mechanisms and the Cuckoo Search Optimization Algorithm to promote the security of the healthcare data in the cloud computing system. I have observed that cloud solutions are now at the center of the contemporary health care systems, and security of patient's data remains a top priority. Earlier used encryption techniques, though secure if implemented, have problems in the way that data is to be processed first it has to be decrypted and then made ready for use - it is in this phase that data can be easily hacked into. Homomorphic encryption provides solution to this issue since it enables one to perform computations on encrypted data while maintaining its confidentiality. However, it takes a lot of computation which presents a lot of problems even in terms of simple performance. The Cuckoo Search Algorithm, a new nature-inspired metaheuristic, is incorporated into the encryption process to provide further optimization, whilst preserving the security benefits of the algorithm. The use of the proposed methodology takes place employing Python and its deployment at the cloud platform with elaborated dataset containing anonymized records extracted from electronic health records. The outcome proves that there are great enhancements in encryption and decryption time, computational complexity, and capacity, and thereby making the system appropriate for real-world healthcare solutions. This research offers a strong base for protection of healthcare data in cloud and is useful for the enhancement of adaptive, comprehensive and secure cloud computing systems. © 2024 IEEE.

Flapping wing aerial vehicles are nowadays in demand due to surveillance, civil needs, espionage and border missions.A lot of challenges exists in the development of autonomous flight missions for the flapping wing aerial vehicles which weigh less than 2 kg. This research focused on the development of data driven control system mathematical model and implementation on flapping wing platform in order to realize the autonomous flight. In this research,behavior of flapping wing aerial system is investigated using inertial measurement unit, barometer, GPS and wireless telemetry. In order to develop the mathematical model estimation as we utilized the real time telemetry data by doing flights in the fields. System parameters data was feed back to ground station with wireless telemetry which would do processing of the data to develop the mathematical model for the pitch, roll, yaw and height control behavior. Instead of relying on the theoretical mathematical models, which often are challenging to implement due to a lot complex mathematical calculations involved, system identification approach has been utilized and practically implemented with successful results.
