Special Issue Information

Dear Colleagues,

In intelligent information technology, symmetry and asymmetry play crucial roles. Symmetry in intelligent information technology can be observed in various aspects. For example, in data processing, when there is a balanced and consistent approach to handling different types of information, it reflects a form of symmetry. On the other hand, asymmetry in intelligent information technology is equally important. Asymmetry can be seen in the way that certain data points or events are given more weight or priority than others. For instance, in machine learning algorithms, some features may be more influential in making predictions, leading to an asymmetric treatment of different variables.

In conclusion, both symmetry and asymmetry in intelligent information technology contribute to its effectiveness and functionality. Understanding and leveraging these aspects can lead to more efficient and intelligent solutions in the field of information technology.

Next-generation intelligent information technologies have emerged as pivotal drivers of transformation across a multitude of industries, adeptly addressing complex challenges and enabling widespread applications in key areas such as computer vision, mobile communication, and robotics. In the realm of computer vision, deep learning-based image processing technologies have become integral to applications such as autonomous driving, where they help in real-time object detection and navigation; medical imaging analysis, which enhances diagnostic accuracy through detailed image interpretation; and environmental monitoring, where they facilitate the advanced analysis of ecological data. These technologies are revolutionizing the way visual data are processed and utilized, making significant strides in both accuracy and efficiency.

In mobile communication, advancements like intelligent MIMO  antennas and intelligent reflecting surfaces have markedly improved network performance and reliability. These innovations enhance data transmission rates, expand coverage, and reduce latency, thereby contributing to the overall efficiency of communication systems. The deployment of these technologies supports the growing demand for high-speed reliable connectivity in various applications from urban environments to remote areas.

In robotics, artificial intelligence-driven automatic control technologies are being increasingly applied in sectors such as industrial automation, where they streamline manufacturing processes and improve precision; maritime control, enhancing navigation and operational efficiency in ship management; and logistics, optimizing supply chain operations and warehouse management. These technologies are pushing the boundaries of what robots can achieve, leading to more advanced and autonomous systems.

Looking ahead, the continuous advancements in these technologies are expected to unlock even broader applications across diverse sectors. However, these advancements also bring to light significant challenges, including concerns related to data privacy and security, issues of technology integration and compatibility, and broader ethical and societal implications.

Coastal water accidents have occurred frequently in recent years, and human factors are still the main cause of these accidents. The purpose of this study is to provide a better and safer solution for the symmetry problem of unmanned surface vessels during automatic berthing in coastal waters. In automatic berthing, the symmetry problem refers to whether the USVs can maintain a stable state during motion and positioning, including dynamic symmetry and environmental symmetry. A finite-time controller based on a global nonsingular terminal sliding mode is designed to improve response speed and state consistency. Dynamic uncertainty and disturbance are considered in the design process, which can optimize the control law and effectively ensure the symmetry of the vessel in different states. Then, an event-triggering mechanism based on a dynamic threshold is adopted. In practice, there is excessive operation of the actuator. This mechanism ensures that the actuator is triggered only when the threshold is reached. USVs can adaptively adjust control strategies based on the real-time status, thereby improving symmetry during berthing. In simulation analysis, a pod-driven unmanned surface vessel with good maneuverability is taken as the research object. The results indicate that this control strategy can ensure rapid and consistent response of the vessel when subjected to external disturbances, which helps to maintain the symmetry of the automatic berthing motion under different conditions.
