An approach to intelligent process automation based on a society of BDI-agents is presented in this paper. According to this approach a higher-level multi-agent systems based automation layer supervises an ordinary process automation system. The purpose of the agent layer is to monitor the operation of the lower-level automation system and semi-autonomously reconfigure its control logic when needed. The agent layer operates as a multi-agent system consisting of BDI-agents, which cooperatively create and run reconfiguration sequences on the ordinary automation system in order to adapt its control logic to various situations. The adaptation process may take place both in reactive and deliberative fashion. In this way the approach aims to increase the flexibility and responsiveness properties of the automation system. The approach is demonstrated with a laboratory test process where process startup and fault recovery experiments have been performed. Results from the experiments are described. © 2005 IEEE.

An approach to extend process automation systems with cooperating subprocess agents is presented in this paper. According to this approach a society of subprocess agents supervises an ordinary process automation system. The functionality of this agent layer includes supervising the lower-level automation system, semi-autonomous reconfiguration of its control logic when needed and query processing for external systems. In this way the approach aims for enhancing the operational flexibility of the automation system. The subprocess agents utilize several agent-based cooperation mechanisms in order to be able to perform their tasks. The approach is demonstrated with a laboratory test process where process startup and fault-recovery scenarios have been imitated. Experiences from initial test runs are described, too. © Springer-Verlag Berlin Heidelberg 2003.

The mining sector historically drove the global economy but at the expense of severe environmental and health repercussions,posing sustainability challenges[1]-[3].Recent advancements on artificial intelligence(AI)are revolutionizing mining through robotic and data-driven innovations[4]-[7].While AI offers mining industry advantages,it is crucial to acknowledge the potential risks associated with its widespread ***-reliance on AI may lead to a loss of human control over mining operations in the future,resulting in unpredictable consequences.

An Analysis of Driver's Avoiding Maneuver in a Highly Emergency Situation

SICE Journal of Control, Measurement, and System Integration 2015年第1期8卷 27-33页

作者： Makoto Itoh Marie-Pierre Pacaux Lemoine Fré dé ric Robache Hervé Morvan Faculty of Engineering Information and Systems University of Tsukuba Laboratory of Industrial and Human Automation Mechanics and Computer Science University of Valenciennes

This paper discusses driver's emergency avoiding behavior while he or she is driving a car in a rural area. Based on behavioral data obtained from an experiment conducted in France with a high-fidelity driving simulator, the authors analyzed the driver behavior just before the collision. The results showed that the drivers tended to choose a “rational” behavior to avoid the collision by using the available visual cues even though the situation is extremely time critical, i.e., the time to collision was only approximately 1.5 seconds.

Monotonic curvature plays an important role in industrial design and styling of curves with aesthetic shapes,e.g.,in automobile and aircraft design[1].Used in conventional parametric CAD/CAM systems,general B-splines are not adequate for aesthetic *** for the straight line and circle,monotonic curvature distribution,associated with pleasing shape,is very difficult to achieve.

This paper presents a novel biological neural networks based on memristive Tabu learning neuron (MTLN) model influenced by electromagnetic radiation. Despite the model having an unstable equilibrium plane, numerical investigation without the influence of electromagnetic radiation reveal that when increasing the memristor strength induces complex phenomena, including the coexistence of infinite bubbles of bifurcations, offset plane coexistence of various attractors. Furthermore, electromagnetic radiation can significantly impact the system's behavior, giving rise to hyperchaotic dynamics. A decent understanding is seen between the mathematical outcomes, approved through trial execution on an Arduino microcontroller-based. The insights gained from neural dynamics could pave the way for applications in neuromorphic computing, engineering, and brain-machine interfaces. Based on the complex dynamics of the model, a data privacy of biomedical data has been build and reveals good results, and enable to resist to robust attacks. © 2024 The Author(s)

In this paper, we propose a novel classification algorithm, called geometrical probability covering (GPC) algorithm, to improve classification ability. On the basis of geometrical properties of data, the proposed algorithm first forms extended prototypes through computing means of any two prototypes in the same class. Then Gaussian kernel is employed for covering the geometrical structure of data and used as a local probability measurement. By computing the sum of the probabilities that a new sample to be classified to the set of prototypes and extended prototypes, the classified criterion based on the global probability measurement is achieved. The proposed GPC algorithm is simple but powerful, especially, when training samples are sparse and small size. Experiments on several databases show that the proposed algorithm is promising. Also, we explore other potential applications such as outlier removal with the proposed GPC algorithm. © Springer-Verlag Berlin Heidelberg 2005.
