Nous présentons les résultats d’une recherche pour l’action visant à la gestion de biodiversité dans bocages. Deux facteurs ont été testés vis-à-vis leur pertinence évaluer : l’un local (note Plan durable des haies, PGDH) et l’autre paysager (grain bocager) contrôlant réseaux bocagers. La note PGDH se rapporte structure haies (hauteur, densité boisement, base). Le grain bocager combine géométri...
As the result of a steady increase in reach, range and processing capabilities, information technologies no longer appear as independent, but rather as integrated, parts of largescale networks. These networks offer a shared resource for information delivery and exchange to communities that appropriate them for their respective purposes. Knowledge and understanding of such information infrastruc...
Integral to effective critical infrastructure analysis is the assessment of infrastructure vulnerabilities, which provides insights into potential disruptions that can enhance protection plans and response and recovery operations. Effective critical infrastructures analysis, however, must account for the complex, multi-dimensional characteristics of infrastructures and the dependencies between ...
Information infrastructures of businesses and government are increasingly interwoven.

Moreover, it is clear that such mass transportation systems are particularly attractive for terrorists, due to the potentially far-reaching, often “spectacular...
Recent years have witnessed a dramatic increase in the use of large-scale distributed infrastructures in many different domains. Efforts in data center consolidation lead to data centers consisting of thousands of machines at one site. Networking testbeds such as Emulab [1] and PlanetLab [2] provide researchers with access to hundreds of machines instantly. Federated computational grids like Gr...
Since the early days of the world wide web (WWW), the information infrastructure provided over the Internet has improved considerably. The simplicity of offering and accessing data on the WWW and the increase of commercial uses of the Internet are major reasons for this development. During this development, it was discovered that shifts in popularity of content and services offered over the web...
