In this paper, a network laboratory for distance learning of basic concepts in IP networking is presented. Through a web interface, students can choose various configurations of a real private network (number of routers and subnetworks, use of IPv4/IPv6, etc.), and learn about them using Linux network commands. The utilization of the virtual laboratory and(More)
In this work we present a tool for Adaptive Support for Collaborative and Individual Learning (ASCIL). Taking as a base the fact that learning is not solely an individual nor collaborative process, we have come to the conclusion that it is an integrated activity which requires integral support. We have therefore applied two previously developed systems,(More)
This paper presents a tool, for the analysis and regeneration of web contents, implemented through XML and Java. At the moment, the web content delivery from server to clients is carried out without taking into account clients' characteristics. Heterogeneous and diverse characteristics, such as user's preferences, different capacities of the client's(More)
The explosive growth of Internet during the last years has been reflected in the ever-increasing amount of the diversity and heterogeneity of user preferences, types and features of devices and access networks. Usually the heterogeneity in the context of the users which request web contents is not taken into account by the servers that deliver them implying(More)
In this paper we present an implementation using XML and Java (X-SHAAD) based on a modular architecture of SHAAD to support a web-based Adaptive Hypermedia System. This architecture considers the hypermedia adaptation along three different " adaptivity dimensions " : user characteristics, technology (the network and the user's terminal), and user(More)
The heterogeneity problem (in terms of different types of access devices, network bandwidth, preferences/characteristics of the user, etc.) has become a major problem for the Internet. Different alternatives have been developed to allow universal access to any type of content. Adaptive Hypermedia Systems (AHS) have emerged as a solution for this. In(More)
