The detection of cyberattacks has been increasingly emphasized in recent years, focusing on both infrastructure and people. Conventional security measures such as intrusion detection, firewalls, and encryption are insufficient in protecting cyber systems against growing and changing threats. In order to address this problem, scholars have explored reinforcement learning (i.e., RL) as a potential solution for intricate cybersecurity decision-making difficulties. Nevertheless, the use of RL faces several obstacles, including dynamic attack scenarios, insufficient training data, and the challenge of replicating real-world complexities. This study presents a novel framework that uses deep reinforcement learning (i.e., DRL) to simulate harmful cyberattacks and improve cybersecurity. This study presents an agent-based framework that is capable of ongoing learning and adaptation in a dynamic network security environment. The agent determines the optimal course of action by considering the current state of the network and the rewards it receives for its decisions. The CIC-IDS-2018 database, constructed using Python 3.7 programming, was used. The conducted studies yielded outstanding results, with a detection accuracy of 98.82% achieved for the CIC-IDS-2018 database in cyber-attack classification. © 2025 by the authors of this article.

A multiband antenna is a good choice to keep the device as compact as possible. This study introduces a tripleband antenna that is well-suited for 5G New Radio applications, satellite communications, and WiMAX. The antenna design has a two-layer substrate, including a ring-slotted rectangular superstate. To meet the design requirements, a rectangular superstate was used to provide the antenna with its triple-band capabilities. The antenna's triband capabilities come from its rectangular superstate, constructed using a ring slot at every antenna's four patch corners. In addition, it is advised and used to employ two FR-4 substrates that are 1.5 millimeters each to improve the antenna's efficacy substantially. The three frequencies shown by the results of the antenna modeling cover the frequency range used by 5G NR service operations: 4.780 GHz, 5.50 GHz, and 10.75 GHz. In each operational range, the measured reflection coefficient has a value below -10 dB at the frequency center, while the peak gains surpass 7 dBi. Nevertheless, the antennas provided in this context exhibit a broad spectrum of applications within the realm of wireless communication. © 2023 IEEE.

In the landscape of optimization for mitigating the Peak-to-Average Power Ratio (PAPR) in Multiple-Input Multiple-Output and Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems, prevalent techniques like the tone reservation scheme and l-norm Cyclic Algorithm (LNCA) algorithm grapple with inherent challenges linked to computational complexity and iterative algorithm derivation. While strides have been made with models such as Twin Symbol Hybrid Optimization by the premise of Partial Transmit Sequence (TSHO-PTS) and Advanced Switching Differential Evolution (ASDE), persistent concerns related to symbol overlaps and algorithmic limitations underscore the need for further refinement in computational efficiency within OFDM-based communication systems. In response to these challenges, the proposed Nonlinear Inertia Weight Factor within the Whale Optimization Algorithm (NIWF-WOA) emerges as a solution. Comparative analysis against existing methods like LCNA, Modified Dragonfly Optimization algorithm (MDOA), TSHO-PTS, and ASDE reveals the superior performance of NIWF-WOA. Numerical validation affirms its efficacy, with a recorded in Bit Error Rate (BER) of 10-2.5, SNR 10-3.4 and PAPR of.10-4.2, underscoring the substantial improvement achieved by NIWF-WOA in optimizing PAPR reduction for MIMO-OFDM systems. © 2024 IEEE.

Characterization of Vertical Wind Speed Profiles Based on Ward's Agglomerative Clustering Algorithm

Wind turbine blades have been constantly increasing since wind energy becomes a popular renewable energy source to generate electricity. Therefore, the wind sector requires a more efficient and representative characterization of vertical wind speed profiles to assess the potential for a wind power plant site. This paper proposes an alternative characterization of vertical wind speed profiles based on Ward's agglomerative clustering algorithm, including both wind speed module and direction data. This approach gives a more accurate incoming wind speed variation around the rotor swept area, and subsequently, provides a more realistic and complete wind speed vector characterization for vertical profiles. Real wind database collected for 2018 in the Forschungsplattformen in Nordund Ostsee(FINO) research platform is used to assess the methodology. A preliminary pre-processing stage is proposed to select the appropriated number of heights and remove missing or incomplete data. Finally, two locations and four heights are selected, and 561588 wind data are characterized. Results and discussion are also included in this paper. The methodology can be applied to other wind database and locations to characterize vertical wind speed profiles and identify the most likely wind data vector patterns.

This paper presents a feasibility study of a pH sensor utilizing the microwave transmission technique within the CST Microwave Studio software. The resonator is designed based on the modified split ring resonator shape (SRR) by incorporating six segments in a circular shape. The proposed resonator shape resembles a honeycomb structure with a capacitive gap to enhance the electric field (E-field) distribution in its area. The operating frequency is set to the Industrial, Scientific, and Medical (ISM) band of 5.82 GHz. According to the simulation, the E-field demonstrates its maximum strength at the focused area, measuring 29,863 V/m. Consequently, this position is deemed suitable for selecting the sensing area for liquid-mixture detection. To investigate the performance of the proposed sensor, the industry model of a Teflon tube is imported and placed atop the focused honeycomb resonator. The performance of the proposed sensor is evaluated by modeling various liquid samples, adjusting electrical properties such as relative permittivity, Εr, and loss factor. The simulated results indicate that the proposed sensor provides a satisfactory transmission coefficient, S21, response for classifying relative permittivity, Εr, changes within the range of 1 to 81. However, for future development, the proposed sensor will undergo fabrication and further investigation to assess its performance in practical applications. ©2023 IEEE.

This paper presents the evaluation of the efficiency and accuracy of the stereo matching algorithm using a census transform with the non-local aggregation technique. This technique is proposed to reduce the average error of the overall matching process in order to produce an accurate disparity map and to access the efficiency of the matching algorithm. Fundamentally, the stereo matching process highly depends on the quality of the image pair. The properties different between left and right images such as image brightness, exposure, occlusion and less texture area have a significant influence on the matching algorithm's accuracy. Thus, this paper analysed the performance of the stereo matching algorithm using Census Transform at matching cost computation, the non-local technique of cost aggregation and winner-take-all strategy at cost optimization. The initial disparity value obtained in cost optimization is used as the final disparity map. The disparity maps obtained from three different aggregation methods are evaluated in terms of accuracy and processing time. The experimental results using the Middlebury dataset show that the non-local method is more accurate compared with other aggregation methods and while maintaining the efficiency of the algorithm. © 2022 IET Conference Proceedings.
