Research of Heterogeneous Database Interactive Modelin Distributed Sale Management Based on Network;

With the development of cognitive psychology and psycholinguistics since 1960s,bottom-up model,top-down model,interactive model and schema theory came into existence one after another in the study psychological process in reading,among which interactive model and schema theory have a greater influence on foreign language teaching.

The interactive model views reading as a process during which the brain receives visual information and at the same time, interprets or reconstructs the meaning the writer had in mind when he wrote the text.

Recognition of Interaction Pattern in Web-based Collaborative Learning;

In this paper, the interaction patterns and their automatic analysis in spontaneous spoken information-seeking dialogues are studied.

A scheme is presented to improve the following deficiencies of the NS emulator: inflexible interactive mode, limited scalability of packet filtering mechanism and single thread implementation.

In the interactive mode, the commands allow the processor to read/modify memory areas, set environment variables, download data from the serial port or from the Ethernet interface and execute code routines.

Aimed at the implementation and interactive mode design of communication network simulation platform for radar networking, the interactive component of network emulation was designed and implemented by using object-oriented and multi-thread technologies, which is proved to be effective for radar network simulation interactive mode, and also of reusability, extensibility and easiness for use.
