Track report of collaboration tools for preservation of environment and cultural heritage (COPECH 2014)
No full textThe COPECH workshop is at its second edition and aims to exploit the interface between research, technology and experience to explore novel research, new techniques, emerging communication platforms and collaborative paradigms or new features of traditional ones about Preservation of Environment and Cultural Heritage. This paper reports in section one the motivations and scope of the workshop. Section two is devoted to a brief description of papers accepted for presentation at this edition
Design of active learning strategy through agile development methodologies: a technological view
Full text linkThreshold-based reconfiguration strategies for gracefully degradable parallel computations
No full textThe occurrence of faults in multicomputers with hundreds or thousands of nodes is a likely event that can be dealt with hardware or software fault-tolerant approaches. This paper presents a unifying model that describes software reconfiguration strategies for parallel applications with regular computational pattern. We show that most existing strategies can be obtained as instances of the proposedthreshold-basedreconfiguration meta-algorithm. Moreover, this approach is useful to discover several yet unexplored strategies among which we consider the class of theadaptive threshold-basedstrategies. The performance optimization analysis demonstrates that these strategies, applied to data-parallel regular computations, give optimal results for worst fault patterns. A wide spectrum of simulations, where the system parameters have been settled to those of actual multicomputers, confirms that adaptive threshold-based strategies yield the most stable performance for a variety of workloads, independently of the number and pattern of faults
A Social Network Based-Enhanced Learning System
No full textThe availability of p2p distributed systems on wireless networks makes possible to explore new e-learning paradigms for adapting learning workflow to be more interactive. In this work we give a preliminary description of EduSHARE that is a p2p-based quiz management system running on wireless ad hoc network and supporting traditional learnong workflow with a dynamic interactive quiz sharing and evaluation syste
A Model transformation framework to boost productivity and creativity in collaborative working environments
No full textA Model-driven approach for designing adaptive web GIS interfaces
No full textAdaptive WEB GIS systems are emerging as a promising technology for managing highly dynamic situations such as in emergencies. Such situations require quick response and combination of static and dynamic data. Context information is crucial for understanding the possible roles within the rescue teams and the possibility for their collaboration. Emergency conditions require adjustments of performance and behavior according to the information and activation of the components and according to the needs of the users. In this paper, we propose a context-aware meta model for a WEB GIS interface. This model is based on the unified modeling language (UML) and the model driven architecture (MDA) paradigm. The proposed framework is described in terms of an emerging web engineering paradigm by specializing a meta model transformation that adapts WEB GIS interfaces to the context information. A study case is taken from a flood emergency scenario. A discussion of the corresponding technological framework, together with a description of a test case, is given in order to show the feasibility of the proposed concept
