The web is evolving towards richer contents and diverse media that are accessed with different devices through multiple kinds of network. This heterogeneous, mobile and changing environment requires that multimedia information delivered by servers be adapted to the actual conditions of use. For that purpose, a number of methods, languages, formats and protocols are developed, especially by W3C....

In this article, we present an adaptive mobile learning system to provide learners with adaptive learning contents according to learners' abilities and learning preference by the specifications of mobile devices. We used both Bayesian inference and content adaptation technologies to construct a dynamic learner model and to create adaptive contents for learners in a Web-based mobile learning env...

We have recently proposed an application-level QoS adaptation service for roaming between wireless networks that are based on different technologies [1] (‘inter-tech’ roaming [2]). The service is a central part of the content distribution platform that we have introduced in [3]. In this extended abstract, we briefly discuss the platform (Section 2), the adaptation service (Section 3) and its su...

At present the grid workflow is a focus topic in the research on grid technologies, but few approaches are provided for designing and checking the grid services adaptation in a workflow, especially in a formal way. As a mobile process algebra, Pi-Calculus is suitable tool for modeling and analyzing distributed, concurrent and dynamic system, such as grid workflow. Addressing the protocol level ...

Instance weighting has been widely applied to phrase-based machine translation domain adaptation. However, it is challenging to be applied to Neural Machine Translation (NMT) directly, because NMT is not a linear model. In this paper, two instance weighting technologies, i.e., sentence weighting and domain weighting with a dynamic weight learning strategy, are proposed for NMT domain adaptation...

This paper proposes an alignment adaptation approach to improve domain-specific (in-domain) word alignment. The basic idea of alignment adaptation is to use out-of-domain corpus to improve in-domain word alignment results. In this paper, we first train two statistical word alignment models with the large-scale out-of-domain corpus and the small-scale in-domain corpus respectively, and then inte...

This article will first describe some recent advances related to multimedia communications over mobile wireless links, including some contemporary communication and networking technologies, mobile devices technologies for receivers, and related signal processing technologies to enhance the performance of multimedia communications. Through the analysis of these recent advances, this article will...

This paper presents and discusses data on the use of technology in general and of Web 2.0 platforms and services in particular by students at the University of Milano-Bicocca. The data was obtained from a survey on media consumption habits and usage of new web technologies conducted by the university’s Observatory on New Media, NuMediaBiOs. Research of this kind provides a valuable basis for th...

The progress realized in the development of enabling technologies that are essential in performing high fidelity computational field simulations is presented. These enabling technologies include geometry-mesh generation and adaptation, visualization and feature detection, virtual reality, parallel and distributed computing, and problem solving environment and framework. The development of toolk...

Web Service compositions combine characteristics of both the Web service (WS) and workflow technologies. The workflow technology is good at explicitly defining integration logic. Web services bring in standardized service description and communication over the Web, and thus provide for seamless integration across organizational boundaries. The two technologies mutually amplify their benefits in...
