Design of an integrated environment for adaptive multimedia document presentation through real time monitoring

The retrieval of multimedia objects is influenced by factor such as throughput and maximum delay offered by the network, and has to be carried out in accordance with the specification of object relationships. Many current network architectures address QoS from a provider' s point of view and analyze network performance, failing to comprehensively address the quality needs of applications. The work presented in this paper concerns the development of an integrated environment for creation and retrieval of multimedia documents, that intends to preserve the coherence between the different media, even when the process is confronted with a temporary lack of communication resources. This environment implements a communication system that, address QoS from the application's point of view and can help in handling variations in network resources availability through a real-time monitoring over these object relationships

An Open Framework for Integrating Widely Distributed Hypermedia Resources

The success of the WWW has served as an illustration of how hypermedia functionality can enhance access to large amounts of distributed information. However, the WWW and many other distributed hypermedia systems offer very simple forms of hypermedia functionality which are not easily applied to existing applications and data formats, and cannot easily incorporate alternative functions which would aid hypermedia navigation to and from existing documents that have not been developed with hypermedia access in mind. This paper describes the extension to a distributed environment of the open hypermedia functionality of the Microcosm system, which is designed to support the provision of hypermedia access to a wide range of source material and application, and to offer straightforward extension of the system to incorporate new forms of information access

Organizing information on the next generation web - Design and implementation of a new bookmark structure

The next-generation Web will increase the need for a highly organized and ever evolving method to store references to Web objects. These requirements could be realized by the development of a new bookmark structure. This paper endeavors to identify the key requirements of such a bookmark, specifically in relation to Web documents, and sets out a suggested design through which these needs may be accomplished. A prototype developed offers such features as the sharing of bookmarks between users and groups of users. Bookmarks for Web documents in this prototype allow more specific information to be stored such as: URL, the document type, the document title, keywords, a summary, user annotations, date added, date last visited and date last modified. Individuals may access the service from anywhere on the Internet, as long as they have a Java-enabled Web browser

After the education disciplines: teaching theory on-line.

Like all social theorising, the academic study of education is 'reflexive'- complicated by the fact of our immersion in it. This paper discusses an on-line version of an undergraduate teacher-education course, 'Social Issues in New Zealand Education,' that is designed to teach its students how to do such 'situated' educational theorising. Consistent with this theme, the paper is written as a stream-of-consciousness narrative. In an attempt to fix in print the 'counterpoint' of pedagicical theorising in general, as well as more specifically in an on-line setting, it is episodic in structure - more like the lateral leaps of hypertext than the disciplined hierarchies of headings characteristic of the linearity of conventional academic argument. It falls into three parts. The first introduces the online virtual classroom environment in which the teaching takes place. Part two locates the course within more general epistemological issues confronting designers of education (foundations) courses in pre-service teaching degrees in the twenty-first century. In Part three, the syllabus of the course is outlined. The paper concludes with examples of students doing 'situated' educational theorising as they engage with course readings and assignments. Through this multi-layered account, I raise for discussion some broad questions about pedagogy in educational foundations courses in today's environment

Designing and Implementing Instruction on the World Wide Web: A Case Study

This case study describes some tips and lessons learned from a project at St. Cloud State University designed to teach information literacy over the World Wide Web. The information literacy project has two primary components: Under the auspices of LEO: Literacy Education Online (a project to disseminate resources to improve composition and writing skills), to develop content resources providing guidance in library and internet use and application in research; Under the Center for Information Media, to disseminate self-paced instructional modules on library and internet use and application in research that could be used in credit-generating courses. As the two components exhibited considerable overlap, it was decided to develop inter-related resources within a single project environment

Quality Assessment for E-learning: a Benchmarking Approach (Third edition)

The primary purpose of this manual is to provide a set of benchmarks, quality criteria and notes for guidance against which e-learning programmes and their support systems may be judged. The manual should therefore be seen primarily as a reference tool for the assessment or review of e-learning programmes and the systems which support them. However, the manual should also prove to be useful to staff in institutions concerned with the design, development, teaching, assessment and support of e-learning programmes. It is hoped that course developers, teachers and other stakeholders will see the manual as a useful development and/or improvement tool for incorporation in their own institutional systems of monitoring, evaluation and enhancement

On Cloud-based multisource Reliable Multicast Transport in Broadband Multimedia Satellite Networks

Multimedia synchronization, Software Over the Air, Personal Information Management on Cloud networks require new reliable protocols, which reduce the traffic load in the core and edge network. This work shows via simulations the performance of an efficient multicast file delivery, which advantage of the distributed file storage in Cloud computing. The performance evaluation focuses on the case of a personal satellite equipment with error prone channels
