The intelligent computer assisted instruction (ICAI) is now a hot topic of computer assisted instruction. One of the difficulties is how to judge static and dynamic behavior of students in order to adjust teaching strategies according to individual difference of students and to raise learning effect. In this paper, the structured student leaning model based on ICAI is put forward, so that teaching...
An new model-free adaptive controller (MFAC) is proposed, combining the single output TD (tracking differentiator) with the basic MFAC. The novel TD-MFAC method improves the capacity of anti-jamming because of the filter characteristic of the single output tracking differentiator. Furthermore, TD-MFAC method is compared with PID control method. The simulation results show the model-free adaptive control...
The forest fire environment is complex. It is difficult to depict and quantitative analyze the relatives among all elements. The condition of fire scene also becomes more complicated. Everything can't be predicted or recurred. Multi-agent technology provides realizable methods for simulation of forest fire extinguishing with pneumatic extinguisher. In this paper, based on the current situation of...
One difficulty in distance teaching is how to determine static and dynamic abilities of student, which teaching strategies can be adjusted according to individual differences and learning effect can be improved. This paper proposes a structured student learning model. Teaching system can teach students according to their aptitude based on this model. The distance teaching adaptability can be achieved...
With the rapid development of network scale, the current SNMP network management model has not been able to meet requirements. Therefore, a new kind of management system and strategy must be provided to enhance the reliability and performance of the network management. This article discusses problems existed in traditional network and analyses the management system structure and management mechanism...
Active network is a new framework where it not only forwards packets, but also performs customized computation on packets. It provides a programmable interface to users where users dynamically inject services through nodes. This paper discusses the forwarding model and mechanism of message based on active network management model, analyzes the structure and characteristics of this model, and studies...
