Taking "Fundamentals of Computers" public courses as example and starting from the perspective of cooperative learning, this paper proposes an idea of computer-supported collaborative learning which is based on Web 2.0 and using Blog, Wiki as teaching methods. With the accomplishment of the design "Platform of CSCL in 'Fundamentals of Computers' course", this study provides a valuable...
Modern society need a lifelong learning, people need to continue to "recharge" to update their knowledge structure and the capability to keep up with the times. With fast pace of modern life and work pressure, it is difficult to have a full time to learn the knowledge, such as school learning, career training. Mobile learning offers the possibility to solve this problem, learners can be...
A popular web site is expected to deal with a large number of requests simultaneously in the reasonable mean response time. The performance of the web sites mainly relies on hardware performance and the processing strategy of requests. In order to improve the hardware performance, more and more web servers are adopting multi-core CPUs. Moreover, the scheduling algorithm of requests on basis of first-come-first-served...
In the past decade the massive growth of the Internet brought huge changes in the way humans live their daily life; however, the biggest concern with rapid growth of digital information is how to efficiently manage and filter unwanted data. In this paper, we propose a method for managing RSS feeds from various news websites. A Web service was developed to provide filtered news items extracted from...
Second Life, a virtual world, represents the latest and most successful frontier of online services for business, learning, training and entertainment. People have virtual lives in these worlds using personal avatars. We believe that the overall experience will be improved. After Second Life launched 5 years ago, it has spread its effects in worldpsilas e-learning development. Many institutions, universities...
This paper adopts a method of linear fitting to create a model of clock drift rate, and uses this drift rate to adjust time and analyze stability. The paper makes three major contributions to this research area. Firstly, the slave node uses local time and the arrival timestamps, from the reference server, to create offset trend equation, and to retrieve the drift rate of slave node. Secondly, the...
Federated digital libraries are composed of autonomous, possibly heterogeneous information services distributed across the Internet. Interoperation between diverse information services is one of the main challenges faced by FDLs. In this paper we describe an agent based mediator architecture that bridges the gap between heterogeneity systems. All agents communicate with each other by exchanging RDF...
Knowledge management (KM) and supply chain management (SCM) has become the important success factors in this emerging era of information and competitive. This research discusses the sharing knowledge in SCM and presents a hierarchical model of it. The difficulties and complexity of KM in SCM are argued based on complexity theory and complex adaptive system theory. In the fourth section a knowledge...
This article introduces a mining method of Web data in adoption of Web page comparison & analysis within a Web site in light of free chemistry database on Internet. On the basis of treeing and blocking Web pages, the data block of Web page is retrieved after compared and analyzed, and then the data is extracted via the comparison and judgment of more than one page of the same structure and format...
