A privacy-preserving cloud computing system for creating participatory noise maps

Participatory sensing is a crowd-sourcing technique which relies both on active contribution of citizens and on their location and mobility patterns. As such, it is particularly vulnerable to privacy concerns, which may seriously hamper the large-scale adoption of participatory sensing applications. In this paper, we present a privacy-preserving system architecture for participatory sensing contexts which relies on cryptographic techniques and distributed computations in the cloud. Each individual is represented by a personal software agent, which is deployed on one of […]

Methods for semantic annotation of an integrated assessment tool for agricultural systems

Semantic annotation based on ontologies has been proposed as a method to achieve integration in multi-disciplinary and multi-scale integrated assessment tools. In the development of an integrated assessment tool, SEAMLESS-IF, agricultural models, data sources, scenarios and indicators had to be integrated in one conceptual schema, providing the shared definition of concepts and their relationships. This paper describes the different methods used in the semantic annotation of the various elements (i.e. models, data sources, scenarios and indicators) in the SEAMLESS-IF. By […]

Towards a service-oriented e-infrastructure for multidisciplinary environmental research

Research e-infrastructures are considered to have generic and thematic parts. The generic part provides high-speed networks, grid (large-scale distributed computing) and database systems (digital repositories and data transfer systems) applicable to all research communities irrespective of discipline. Thematic parts are specific deployments of e-infrastructures to support diverse virtual research communities. The needs of a virtual community of multidisciplinary environmental researchers are yet to be investigated. We envisage and argue for an e-infrastructure that will enable environmental researchers to develop environmental […]
