The three-electrode sliding dielectric barrier discharge(TES-DBD) plasma actuator significantly enhances the ionization rate and momentum exchange between charged particles and neutral particles by incorporating a parallel DC electrode into the standard DBD design. This design improves the body force and induced jet velocity while allowing flexible control of the induced jet angle, overcoming the limitations of discharge extension and uncontrollable direction in traditional DBD plasma actuators. An integrated plasma power supply has been designed specifically for TES-DBD plasma actuators, streamlining the power supply management. The methodology involves designing the circuit topology for the TES-DBD power supply, followed by simulating and validating its operating principles using Multisim software. The operational performance of the power supply is evaluated through a comprehensive analysis of its electrical,thermal, and aerodynamic properties specific to TES-DBD plasma actuation.

Aiming at the problem of system error registration in the bearings-only location system for surface ships, this paper proposes a registration method based on the genetic algorithm (GA). The presented method directly uses the pure angle observation information of multiple passive sensors to construct the optimal objective function according to the basic principle of error registration. The original problem is then transformed into a nonlinear parameter optimization model with constraints, and GA is used to solve it. The coding mode, fitness function, selection, crossover, mutation and other iterative processes of the GA are properly designed. Numerical simulation results demonstrate that the proposed method can achieve the error registration effectively with high accuracy and reliability. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

In the realm of cybersecurity, this study presents a novel approach to intrusion detection by harnessing the power of artificial intelligence (AI) and machine learning (ML). We delve into the critical domain of network intrusion detection, emphasizing the significance of our research. Existing methodologies face challenges, prompting the need for advanced solutions. Our work addresses this gap by employing an innovative method. Beginning with the collection and preprocessing of extensive network traffic data, we extract key features crucial for characterizing network behavior. Our approach utilizes a deep learning model to effectively categorize network behavior, distinguishing between normal traffic and malicious attacks. Through rigorous experimental validation against established technologies, we demonstrate substantial improvements in key metrics such as accuracy, recall, and F1 score. Beyond performance metrics, we explore the practical deployment potential of our approach in real-world network environments. This research contributes to the ongoing discourse on effective intrusion detection solutions driven by AI and ML in the realm of network security. In conclusion, our study not only enhances the understanding of network intrusion detection but also provides a robust and efficient solution for bolstering cybersecurity in an increasingly interconnected world. © 2023 ACM.

In the construction industry, cement is widely used, and its quality standards are particularly stringent. Among these standards, the compressive strength of cement is one of the most crucial quality indicators. However, existing measurement methods are time-consuming and resource-intensive. This study adopts an innovative symbolic regression methodology to swiftly evaluate cement's compressive strength for quality assessment, even prior to the initiation of the hydration process. Additionally, it facilitates parameter analysis to explore the impact of cement raw material ratios on compressive strength. Additionally, it allows for parameter analysis, enabling research into the impact of cement raw material ratios on compressive strength. Experimental results demonstrate that this algorithm accurately predicts strength and exhibits excellent generalization capabilities. © 2023 IEEE.
