In order to identify the traffic state of urban road network accurately, the traffic state identification methods based on cloud computing model are proposed. The macroscopic and microscopic characteristics of urban road network traffic flow are discussed in detail; and then the identification index systems are proposed. The traffic state identification models are proposed based on cloud computing...
The 5.12 Wenchuan earthquakes has not only caused great loss of lives and properties of people in disastrous area, but also has brought profound psychological trauma to the victims. A post-trauma mobile service (PTMS) is developed and implemented in Sichuan province which combines the psychological counseling knowledge and mobile Internet technology. The PTMS service creates a new mode for long distance...
Wireless Mesh Network (WMN) is an emerging technology that has developed a lot these years. WMN has the feather of self-organization, distributed structure. The main topological characteristic of WMN is that there are only one or several node connecting to the infrastructure network as gateway and all other nodes connect to the gateway through the relay of the neighboring nodes, and then connect with...
Recently, many commercial products, such as Google Trends and Yahoo! Buzz, are released to monitor the past search engine query frequency trend. However, little research has been devoted for predicting the upcoming query trend, which is of great importance in providing guidelines for future business planning. In this paper, a unified solution is presented for such a purpose. Besides the classical...
Dimension reduction for large-scale text data is attracting much attention lately due to the rapid growth of World Wide Web. We can consider dimension reduction algorithms in two categories: feature extraction and feature selection. An important problem remains: it has been difficult to integrate these two algorithm categories into a single framework, making it difficult to reap the benefit of both...
Sustainable utilization of natural resources is a hot topic that is concerned about in the 21st century. With the fast development of information technology, it is necessary that we should build an information service system of sustainable utilization of natural resources based on Web. After introducing the connotation of sustainable utilization of natural resources and the theory of information services...
Currently, it's a challenge to provide differentiated quality media services in Internet, especially under peer-to-peer (P2P) model. Most P2P based algorithms are not support the service scalability. In this paper, we propose an optimized algorithm, which integrate an excellent P2P algorithm SIM and scalable video coding (SVC) technology for media streaming (SPM). Hosts in SPM can specify media quality...
To satisfy current requirements of Web applications and solve the existing problems in Web application development, an extended MVC-based Web application framework based on XML on J2EE platform is put forward that is more flexible, expansible and maintainable. According to the characteristics of structured and unstructured machine tool product data in Web based distributed cooperative design environment,...
