针对节点数量较多、功能类型多样的控制器局域网(controller area network,CAN)中存在的管理问题,基于其协议技术标准和OSEK/VDX规范,提出并实现了一种网络管理的改进策略。该策略可实现直接网络管理中CAN节点的分组管理和合并。实验结果表明,这种网络管理机制能够快速构建网络管理的逻辑结构,提高了CAN网络管理效率。
The quantitative understanding of human behavior is a central question of modern science. Because of the complexity of human behavior, it is almost impossible to seek regularities in human dynamics. It is assumed that human actions are randomly distributed in time in current models for human dynamics. While the characteristics of human behavior combined with the queue model are considered as model for human dynamics based on habit to explain bursts and heavy tails in human dynamics more exactly. Normal distribution is used to simulate intervals of succession of events, and random parameters are set as unexpected events disturbing habit behaviors. Moreover, duration of events are proposed to imitate continual attention to some events in human behaviors.
