Withthe development of in-vehicle network (IVN) technology, the real-time performance and reliability of vehicle Ethernet become very important. Time-sensitive network (TSN) has become a new technical solution for vehicle Ethernet because of its high accuracy of data transmission. To solve the problem of low scheduling efficiency and poor real-time transmission in traffic scheduling in TSN, the optimization of traffic scheduling time is studied in the network from the aspect of scheduling algorithm. Firstly, the time slot scheduling model of time-sensitive flows is established. then, a hybrid scheduling strategy considering traffic routing and traffic scheduling optimization is designed. In the routing strategy, the ant colony algorithm is designed to optimize the traffic transmission path. In the scheduling strategy, a time planning model is established and the global scheduling schedule is optimized by mixed integer programming algorithm. Finally, the traffic scheduling simulation and gated scheduling experiment verify that the proposed scheduling optimization algorithm can significantly improve the efficiency and real-time performance of traffic scheduling in vehicle TSN.

the Product-of-Exponential (POE) model simplifies kinematic modeling by establishing direct relationships between kinematic and end-effector errors using base coordinate and tool coordinates. However, It contains numerous parameters and high latitude, which may lead to reduced efficiency and precision in the case of limited test data. this paper introduces the Simplified Effective Kinematic Calibration (SEC) technique, combining the Simplified Product-of-Exponential (SPOE) model, Pre-processing Sequential Quadratic programming (PSQP), and Gaussian Process Regression (GPR) to enhance calibration accuracy and efficiency. the SEC technique reduces parameter identification dimension, identifies coordinate transformation, compensates for geometric errors, and uses GPR for non-geometric error compensation. Experiments show that SEC demonstrates better positioning accuracy and efficiency than traditional methods.

In the context of a highly interconnected energy landscape, coordinated cyber-physical attacks on integrated energy systems can cause significant damage and trigger considerable economic impacts. In order to ensure the robustness and uninterrupted function of such systems, the interaction between information and physical matrix is analyzed based on the inherent coupling mechanism unique to the integrated energy information-physical framework. After the basic analysis, a threelayer dynamic game model is designed using the strategy of game theory. the model is transformed into a mixed integer linear programming formula, load loss is selected as the vulnerability assessment index, and defense resources are effectively allocated to each component of the integrated energy system. Finally, an IEEE-39-node grid is coupled to an 11-node gas distribution network. Research and analysis, the proposed model and its related methods have been verified.

Withthe deepening reform of the electricity market in China, the study focuses on incentivizing distributed energy storage to provide frequency modulation ancillary services to the power system through market-based mechanisms. the research investigates the transaction decision-making of distributed energy storage in the energy and frequency modulation ancillary services market. An overall trading framework for the energy and frequency modulation ancillary services market is proposed. A bi-level decision model is developed, considering both maximizing the revenue of distributed energy storage and minimizing system costs. A hybrid integer linear programming equilibrium solution algorithm is designed based on duality theory and KKT conditions conversion. the effectiveness of the proposed model is verified through case analysis. the results demonstrate that the revenue from distributed energy storage accounts for more than 50% of the total revenue in the frequency modulation market, and strategic bidding by distributed energy storage can increase its revenue.

At present, withthe continuous increase of arge public buildings, people have higher requirements for the comfort, health, and efficiency of their internal environment. therefore, how to effectively improve the health and efficiency of indoor environmental quality in large public buildings has become a focus of attention, and improving the indoor environmental quality of large public buildings requires accurate monitoring and scientific evaluation. Withthe increasing demand for indoor environment, scholars have conducted a lot of research on it, but most of the research only focuses on indoor thermal environment or air quality, lacking comprehensive evaluation of indoor environmental quality. the fuzzy comprehensive evaluation method is commonly employed when conducting comprehensive assessments of indoor environmental quality, despite its inherent subjectivity. To address these limitations, this article establishes an indoor environmental quality evaluation model for large public buildings using Projection Pursuit (PP) and Accelerated Genetic Algorithm (AGA). the results demonstrate the feasibility of the proposed model for assessing indoor environmental quality. this method is characterized by its clear concept, logical coherence, ease of computer programming, and the provision of true and accurate comprehensive evaluation results. Furthermore, this method exhibits attributes of simplicity and universality.

Real world signals, being analog by nature requires analog signal processing. But unfortunately analog domain still lacks of good research on analog EDA tool. therefore, developing systematic synthesis methodology is a major research topic still to be addressed and improved to cope up withthe recent technological advancements in VLSI. In this background, a graph has been employed to represent synthesis methodology for linear analog filters in a systematic way. Nodes of bipartite graph represents some basic first order mathematical functions; those are connected through weighted edges (with relation operator). Traversal of the graph with defined traversal rules gives different subgraphs implementing different types/order of filters. the graph has been optimized with some defined set of rules. Optimized graph has been converted into a multifunctional filter structure, which realizes all types of filters by programmingthe connections among the building blocks. this systematic synthesis approach supports reusability and programmability in hardware, when implemented in gm-C. Filter response is verified through SPICE simulation.
