This paper studies the spectral properties of two important graph matrices in the literature, known as the leader-follower matrices. These two matrices arise from various cooperative control problems of multi-agent systems in a leader-follower architecture, and in most cases, they are the keys to the solvability of these cooperative control problems. In contrast with the existing results, which appeal to the algebraic graph theory and matrix analysis tools, we reveal the spectral properties from the viewpoint of dynamical systems. In particular, the spectral properties of the two graph matrices are derived by analyzing the convergence of a continuous-time and a discrete-time linear system, respectively. © 2024 Technical Committee on control Theory, Chinese Association of Automation.

The multi-point access of large-scale integration of wind and solar energy has brought negative effects such as voltage over-limit to the operation of the distribution network, which increases the difficulty of reactive power optimization. In order to solve this problem, an improved particle swarm optimization scheme based on Tent-Chebyshev fusion switching is proposed. When the Tent chaotic mapping function is used to calculate the initial position of the particles, the Chebyshev chaotic mapping function is used to introduce random disturbance to the particles trapped in the fixed point in the population, so that they can re-enter the chaotic state. It mitigates the risk of converging into local optima, minimizes the network loss and voltage deviation of the distribution network system. The research results are verified through the IEEE33-node example, demonstrating the feasibility and effectiveness of the proposed method in addressing the reactive power optimization problem. © 2024 IEEE.

In the context of human/equipment interaction processes, human error has become a significant factor influencing performance risk in professional theaters. To address this issue, the Cognitive Reliability and Error Analysis Method (CREAM) is integrated with fuzzy inference to assess the human reliability of theater staff and predict the probability of human error (HEP). Additionally, Grey Relational Analysis (GRA) is introduced to determine the weights of Common Performance Conditions (CPCs) within CREAM. Through this methodological framework, human reliability analysis of theater operators is conducted, enabling the prediction of human error rates across various scenarios. Subsequently, corresponding measures are provided, culminating in an effective solution to enhance performance safety within theatrical environments. © 2024 IEEE.

With the rapid development of high-speed railway, it is necessary to ensure the safety of railway running, and the computer interlock system is the key equipment to ensure the safety of railway running in the station. It is a real-time system with high safety and reliability, which needs comprehensive and strict testing before it is put into use. In order to ensure that the interlocking system can strictly complete the function of each part, the computer interlocking test is very important. In recent years, with the rapid development of deep learning and image processing technology, in order to further improve the test efficiency of computer interlocking system, this paper studies the result decision module of automatic interlocking test. Target detection algorithm YOLOv5 is adopted to realize the location and recognition of signal, switch and section icon on the interlocking interface. © 2023 SPIE.

Urban rail transit passenger flow prediction encounters two primary challenges: the inability to effectively capture the variations in passenger flow patterns and the limited accuracy of prediction models. Therefore, this paper proposes three improved Ensemble Empirical Mode Decomposition (EEMD) methods to accurately capture the characteristics of passenger flow sequence data: (1) Grouped Reconstruction of IMF (Intrinsic Mode Function) Components in EEMD;(2) High-Frequency Disturbance Removal EEMD;(3) Hybrid EEMD. Simultaneously, a short-term passenger flow combination prediction model for urban rail transit stations is established. In order to enhance the prediction accuracy and robustness of the model, the base models utilized include XGBoost, LightGBM, and LSTM. Additionally, the Stacking ensemble method is employed to fuse the models together. Finally, a short-term passenger flow prediction model for urban rail transit based on improved EEMD and ensemble learning is constructed. Taking the entry passenger flow of Beijing West Station in the Beijing Subway as an example, the effectiveness of the model in predicting short-term passenger flow in urban rail transit is validated. © Beijing Paike Culture Commu.

This research focuses on optimizing the latching stability of spring operating mechanism. By analyzing the mechanical properties of the tripping mechanism, identifying key components, and investigating the impact of the latching volume on the circuit breaker's closed state, a dimensional chain model is established for tolerance chain calculation and analysis. It is found that the existing spring operating mechanism have insufficient tolerance matching, leading to deviations in the latching volume from the ideal range. Employing tolerance chain simulation, critical components and their dimensions are determined, assessing their sensitivity and contribution to performance. Integrating stress simulation analysis to account for the influence of key component deformation, design tolerances are optimized to meet technical specifications. This study effectively enhances the design reliability and operational performance of spring operating mechanism. © 2024 IEEE.
