Building a cloud-based e-learning platform using the approach of the research field of learning analytics is the overall goal of this research study. With the strengths of a cloud service it is possible to add value to the learning process for all stakeholders. With such a solution, the process of collecting, analyzing and interpreting data becomes rather easily. This research study aims to introduce...
With the rapid development of network technology, human beings gradually stepped into a new era. College teaching way has not make full use of network resources, especially sports teaching, the traditional teaching method still occupies the dominant position. In recent years, as a result of college expansion, caused part of the site and the shortage of teachers College. The emergence of network teaching,...
Over the past decades, the importance of multimedia services such as video streaming has increased considerably. Since streaming protocols such as Real Time Streaming Protocol (RTSP) and Real Time Transport Protocol (RTP) require server-side bit-rate adaptation schemes, they are not ideally suited to deal with highly heterogeneous and dynamically changing network conditions. Therefore, research shifted...
In IP multimedia subsystem (IMS), in order to have a multimedia service first a session should be established. The signaling part is done by the SIP protocol-the most important protocol used in IMS network. Excessive signaling during the session setup mechanism leads to an undesirable delay in session establishment and also the final response of the other subscriber. This matter is considered important...
In order to improve the level of higher education support services and enhance their ability to participate in social competition, based on modern information technology and network multimedia technology, to establish a logistics service network support systems on ISO9001 certification, is to achieve modernization of university management system certification and standardization of the urgent need...
IP Multimedia Subsystem (IMS) is well known for its combination of the capability of universal coverage of mobile network and rich application development environment of IP network. IMS has been welcomed by both industry and academic society, becoming the first choice of the Next Generation Network (NGN) technologies. This paper describes the design and implementation of three IMS teaching lab experiments,...
In the last decade, information and communication technology has been developing rapidly. From multimedia and integration concept comes Classroom Suite (CRS), a system that enhance educational process for better education system in the school. CRS helps school in rural areas that lack of proper educator. CRS provides educational content so that an educator can teach some subject even he/she isn't...
Based on the tourists' requirements for tourism information, the structure and function of tourism service WebGIS have been systematically designed with Silverlight technology. According to the requirement of systemic construction, the key technologies have been studied and analyzed, including Silverlight, WebGIS, and database technology. Finally, the tourism service WebGIS in Kaifeng city is developed...
In this paper, we introduce a scheme that enables secure image trading over the Internet. The involved parties in our image trading system are image provider, server provider, and commercial user. The proposed scheme facilitates secure storing and retrieval of original images for trading, but prevents access to unauthorized users and untrustworthy server provider. The original images are visually...
This paper integrates search engine with Cloud Computing, introduces a user interest model on the premise of the advantages of the two above and through analysis of search demands of users, and push results obtained through cloud search and close to demands to users immediately by existing server push technology. It shows through experiment that the search engine under Cloud Computing can express...
IMS is the subsystem proposed by 3GPP which supplies IP multimedia services, meeting the trend of integrating of communication networks. The common function of an IMS terminal includes data communication (instant message),multimedia communication (video and audio calling) and presence. Document-sharing application is based on the whiteboard application, of course, it is a bright spot of whiteboard...
The widespread use of SIP has exposed a lot of vulnerabilities in this protocol. Among them, overload can cause serious problems for SIP servers. SIP overload occurs when a SIP server does not have enough resources to process messages. In this paper, we proposed effective methods to control SIP server overload based on the Window-Based overload control method, considering not only the maximum window...
In this paper we use prefix cache and patching algorithm which are administration way for cache. The system of proxy cache for streaming media is achieved, which is referred to operation principle of streaming media service and used RTSP protocol. In addition, it considers bytes benefit of stream media file and the size of file block, so it is more reasonable when move data block out of cache. It...
Due to the recent popularization of digital broadcasting systems, selective contents broadcasting depending on viewers' preference, have attracted attention. For example, in a quiz program, a user selects his answer and watches the video content for the answer. When the server deliver programs reflecting users' preferences, clients have to wait until their selected contents start playing. Therefore,...
In order to promote students' development, process evaluation and multiple evaluation will gradually replace the traditional single summative evaluation. The massive web construction and the already extended college English self-directed teaching mode have required the development of college English multiple evaluation, and provide favorable conditions for it as well. This article forwards a plan...
Improving the learning process quality of the students is an urgent need, particularly for those in rural areas. A key solution in this Information era is by utilizing Information and Communication Technologies (ICTs). This allows the students to broaden information access as a foundation for developing student learning community (SLC). Our approach to support the SLC through ICTs is by providing...
According to the current situation of multimedia instruction and application of campus network in new local colleges, this paper analyses problems and technical limitations in the process of implementing multimedia teaching; At the same time, combined with new requirements of multimedia instruction using network, it proposes the view that local colleges campus network should possess the ability of...
MERLINGO (MEdia-rich Repository of LearnING Objects) project based on the rich-media technologies application in the eLearning environment is aimed at the building of the central repository of multimedia learning objects in the distributed environment containing teachers' presentations accessible on-line and on-demand within the national academic computer network CESNET2. The article presents integration...
The paper is focused on the application of new generation of ICT in education of children of pre-school and elementary school age. The necessity to use new specific pedagogical approaches and methodology is presented. The conception of ICT environment for e-learning based on IMS NGN architecture including the IPTV subsystem, as well as the specific interfaces including voice controlled human-computer...
A Web-based GIS provides simplicity and interactivity such that some simplified functions of the watershed management can be open in Internet/Intranet for specific users or general public users. A palm-size GPS device provides location information, x and y coordinates, in the observation site that can bring all associate data of physical, chemical, and biological conditions. This paper presents an...
