This paper aims to build a tourism demand- forecasting model that based on the information dissemination mechanism. This study firstly reviewed the methods of tourism demand forecasting and modeling and segments them into different clusters. Then discussed the relationship between tourism demand and information dissemination mechanism. Then build a forecasting model to forecast the tourism demand based on the information dissemination mechanism. This paper use the sample of China's inbound tourist make a comparison of accuracy to an econometric linear regression model. Finally find that the forecasting model based on the information dissemination mechanism performances better than the traditional linear regression model.

We propose Overlay-based Service Distribution Network(OSDN) as a novel platform to convey service through overlay routing. We formulate the OSDN deployment problem in order to build an optimal overlay for a given set of connection demands but find the problem is NP-complete. To obtain a sub- optimal solution, we first design a LASER algorithm to calculate all shortest overlay paths available for a given AS pair and then apply heuristic methods to merge the overlay paths selectively for different AS pairs. Through simulation experiments, we conclude that our approach has a good performance to reduce the construction cost of an OSDN for a given set of connection demands.

The end-to-end time-delay induced by the network is one of the main issues in Networked Control Systems (NCS). In order to compensate the delay more effectively,this paper presents a novel approach to predict it on line using the T-S fuzzy method. The basic idea of this method is to assume that the system dynamics can be described by a set of rules rather than a single one,and the final output is given by a combination of the estimates according to all these fuzzy rules. GK fuzzy clustering will be used in the process of building the T-S fuzzy model and generating the predicted values. By numerical simulations,it is proved that the T-S fuzzy method can predict and compensate the time delay effectively.

The classification performance of the learner is weakened when unlabeled examples are mislabeled during co- training process. A semi-supervised co-training algorithm based on assisted learning (AR-Tri-training) was proposed. Firstly, the assisted learning strategy was presented, which is combined with rich information strategy for designing the assisted learner. Secondly, the evaluation factor was calculated, and noise was eliminated from unlabeled example set by using the assisted learner and the evaluation factor. Finally, three single learners were trained using labeled examples, wrong-learning examples on validation set and less noise unlabeled examples. The experimental results on application to voice recognition indicate that AR-Tri-training can compensate for the Tri-training shortcomings and the average classification accuracy is increased by 15%. As can be drawn from the experimental results, AR-Tri- training not only removes the mislabeled examples in training process, but also takes full advantage of the unlabeled examples and wrong-learning examples on validation set.

Taking advanced teaching theory as a guide, combined with the authors' teaching practice, and using the new teaching design method of "equal emphasis on learning and teaching", an information-based teaching and learning environment, the web-based teaching and learning system, was created through the effective integration of web technologies in the teaching process, which set courses of study, testing, discussions and teaching evaluation in one system. It achieved a kind of informationization educational model which had the characteristics of "dual master, three-dimensional, interaction, network, automation and so on", and thus improved the students' enthusiasm, initiative and creativity effectively. It's important to improve the teaching quality.
