Previous studies on hotel website performance have relied on frequency counting, content analysis or user behavioral approaches. These studies cannot accurately calculate hotel website performance in terms of user assessments of dimension/ attribute weighting and performance ratings. The aim of this research is to develop a scientific model that integrates a set of website evaluation dimensions for...
Audio podcasting has been widely used by many online sites such as newspapers, web portals, journal, etc., to deliver audio content to users through download or subscription. Within 1 to 30 minutes long of one podcast story, it is often that multiple audio advertisements (ads) are inserted into and repeated, with each of a length of 5 to 30 seconds, at different locations. Based on knowledge of typical...
The prevalence of the Internet has promoted the development of the electronic commerce. Digital products shopping system appeared in peoples' eyes. The security problems become very important. The core is how to guarantee the secure and flexible access of the digital products. As the most promising access control model, Usage control has been generally accepted. But the trust problem is the shortcoming...
Collaborative learning emphasizes the good effect of team learning. And computer-supported collaborative learning (CSCL) has become a hot topic in current education field. Various web tools are used in CSCL. But students are not the only roles in collaborative learning. Teacher plays important roles. So this article designed a good web-based collaborative learning model with the help of agent technology...
Through the discussion about the characteristic of the network environment and the library under network environment, this passage analyzes the personality characteristics of knowledge-based librarians in the libraries under network environment and presents the best structural model of knowledge-based librarians. And there comes to the conclusion that only the formation of the best talent structure...
In order to bear reliable end-to-end services transmission in insecure IP network, SCTP as the transport protocol of the next-generation Internet was proposed. The performance of SCTP has been improved in related literature; however, they optimized it based on a single or a few parameters, which is lack of a comprehensive consideration in correlation parameters. In consideration of real-time and the...
This paper based on the current network modes of technology transfer, put forward two new technology-transferred network modes, solve problems in current modes from depth and breadth of technology transfer, it is an innovation and development from technology-transferred neσtwork.
Significances of information technology for teaching and learning were discussed, and students' Preference to applying information technology in graduation design was investigated. Tutorship applying information technology has advantages, such as space-time flexibility, visualization, digitalization and mass information. It can't replace traditional means entirely; however, two means should have complementary...
With the continuous development and improvement of the Internet, Mobile Education Network and Mobile Telecommunications' Equipment and the gradual increase in the level of the rural economy and the concept of modern learning-lifelong learning' in-depth impact and teachers' requirements for further educational technology, mobile learning becomes tools for teachers to develop and improve their educational...
The paper first introduces the theories and principles of the interaction design on the E-Learning courses; then analyzes the interaction design of the "College English Intensive Reading" as well as their technology implementation; finally, sums up the above interaction design and implementation of the experience, as well as suggestions for further improvement.
Structured P2P system doesn't consider the actual physical topology when building the logical overlay, which would cause a serious mismatching between logical overlay network and physical network and affect the routing performance of the system. An advanced algorithm of K-bucket updating strategy base on structured Kademlia system was proposed. Using Landmark Binning algorithm and RTT detection will...
The current routing system of the Internet is in nature best-effort. We often observe, however, that the Internet routing today drops packets upon network abnormalities; even when the network is not congested, and/or physical paths exist. Such strategy usually makes the routing design simple; and even the packet is dropped, well, we know we have TCP. Nevertheless, the key function of any routing system,...
Collaborative tagging is a popular method in social resource sharing system. The reason why collaborative tagging system becomes popular is users can freely tags on the resources, like Flickr1 and Delicious2. Any relationship between tags and resources are not made explicitly when tagging in folksonomy. Due to lack of semantic meaning, it is difficult for users to find related resources. Also, short...
The growth of the internet has incessantly driven the bandwidth demand. In this presentation, we discuss the role of photonics and electronics in the Terabit optical transport poised to emerge within the next decade.
Computer Support Collaborative Work (CSCW) leads to many changes in the field of education and training. Aim at the problems of high expense, fixed training sites, restricted trainee number or time that existed in the widely used simulation system for using it to execute training in the field of education and training, the paper researched on the construction of Virtual Collaborative Training Environment...
The goal of image classification is to classify a collection of unlabeled images into a set of semantic classes. Many methods have been proposed to approach this goal by leveraging visual appearances of local patches in images. However, the spatial context between these local patches also provides significant information to improve the classification accuracy. Traditional spatial contextual models,...
Grid is the next generation information infrastructure of Internet and software running support platform. At present, there are many resource discovery mechanisms in Grid, which can find probably useful resources, including software component. Furthermore, this paper solves the problem of searching trusty component by providing a trust evaluation and component selection mechanism. The simulation experiment...
Matlab has big and powerful functions to scientific calculation. The Matlab applications that use the capabilities of the World Wide Web to send data to Matlab for computation and to display the results in a Web browser were studied by using Matlab Web server. A real physical experiment data treatment system adopted browser/server networking technique based on Matlab Web server has been developed...
With the rapid development of the Internet and Data Storage technology, people intends to store a large number of documents of various types on their PCs, but having no way to manage such heterogeneous data sources in a integrated way, such as data in more structured sources (e.g., spreadsheets), semi-structured sources (e.g., XML documents) and unstructured sources (e.g., text documents). This paper...
With the development of internet technology, the entire amount of data on the internet has shown the explosive growth. Some researchers have paid their attention to find an effective way to store and manage these data. In this paper, we introduce a load rebalancing algorithm to solve the load balancing problem among all chunk servers(compute nodes) in the distributed file system; it also ensures that...
