Based on the Alexa.com site ranking system, this paper study on Facebook and Renren network ,finding the gap between China and the U.S. social network website. By comparing, we can see a big gap between Facebook and Renren network: firstly, Facebook users diversify the sources, while Renren network users have a single source. Secondly, Facebook and Renren network users, who are mainly young people,...
Green supply chain management of agricultural products, whose establishment of trace ability is important, but the lack of appropriate information technology supported in the past. Green agricultural supply chain trace ability system should be established to provide a guarantee with the development of the internet of things. Analysis based on the internet of things in the green agricultural supply...
This paper begins with the uplink bottleneck problem which is common in campus network, relatively analyzes existed solutions of multiple uplinks, and passes an opinion of our own based on that. In order to utilize network resources more fully, and provide a good online working, studying, entertaining environment to the teachers and students, without adjusting the original network structure, we proposed...
We study traffic dynamics and propose a new routing strategy based on the local topological information in scale-free network. According to the new routing strategy with a single tunable parameter, a packet is delivered to next node with probabilities that depend not only on the degrees of the next node but also the estimated waiting time at the new node. The routing algorithm is implemented in BA...
A new routing strategy is proposed based on local information for enhancing the efficiency of traffic delivery on scale-free networks with tunable clustering. The strategy is governed by two parameters. Simulation results show that the capacity of maximum traffic flow is greatly enhanced by the optimal controlled parameter of new routing strategy. Moreover, a simulation is performed in a model of...
Recently time-delayed dual model has attracted great attention in studying Internet congestion control. Stability analysis of time-delayed dual model is an important task, where how to determine its solution is the first step. Usually perturbation method can be used to seek the solution of the model, however, its effectiveness depends on a small parameter and it will be invalid when such a parameter...
It is very important to advance the teaching and management level by using the modern Internet technology. Whether the teaching affairs management information system successful or not is due to the potential of the system could be exploited to maximum. Now we take the construction of the teaching affairs management information system of ZUST as an example to analysis and design the management idea...
The Web2.0 concept encourages rich information exchanging and enables individuals to collaborative with others for content co-creation. Extensive interactions empower brainstorming and leads to numerous innovative ideas. The collective effort of user groups in the cyberspace have becomes an emergent division of social intelligence. Unlike traditional animal social behaviors that physically tight linked...
