Critical infrastructures are highly complex collections of people, processes, technologies, and information; they are also highly interdependent where disruptions to one infrastructure commonly cascade in scope and escalate in impact across other infrastructures. While it is unlikely that disruptions can be prevented with certainty, an effective practice of critical infrastructure analysis can ...

The detailed simulation of interdependent critical infrastructures is a hard problem. Major challenges include modeling multiple heterogeneous infrastructures in a single framework and expressing internal dependencies and interdependencies between infrastructures. This paper attempts to address these issues by proposing a simulation framework where several sector-specific simulators (vertical s...

By bringing together science studies, information science and ethnographic fieldwork in interdisciplinary research the author argues for the relevance of ethnographic practices when studying information systems as infrastructures of communication. Ethnographic fieldwork focuses attention on fringes and materialities of infrastructures and renders the researcher able to read the invisible layers...

Interdependency among critical infrastructures contributes to vulnerabilities of those infrastructures. In this paper, the vulnerabilities of critical infrastructures are identified and analysed using social network analysis. In the analysis of network centrality, the importance of each critical infrastructure, in terms of its contribution to infrastructure interdependency, is ranked. The findi...

Independent development of research infrastructures leads to unnecessary replication of technologies and solutions whilst the lack of standard definitions makes it difficult to relate experiences in one infrastructure with those of ot hers. The ENVRI Reference Model, www.envri.eu/rm, uses the Open Distributed Processing standard framework in order to model the "archetypical" environmental resea...

Information infrastructures and the large amounts of data that are accessible through them offer tremendous potential for innovation. In this workshop, we present and discuss two examples of such high-impact innovations: an open data e-infrastructure and government re-use of a business information infrastructure. Both offer possibilities for innovations in the public sector. The workshop covers...

yasuj is one the cities of the country that has had a heavy growth in recent years. the main objective of this study is t help develop improved urban services using inefficiencies of the current services. the important issue in planning urban infrastructures in estimating infrastructures based on population forecast, which is the focus of this study. the research method used in this study was a...

Investing in RFID technologies along the Supply Chain seems to be the choice of time as a lot of literature and media coverage is about its benefits [1, 2, 3, 4]. Nevertheless, the productivity enhancements achieved by using these technologies strongly depend on the software infrastructure being used. Thus, the extent of benefits regarding productivity can not easily be predicted without evalua...

Spatial data infrastructure (SDI) is the infrastructure that facilitates the discovery, access, management, distribution, reuse, and preservation of digital geospatial resources. These resources may include maps, data, geospatial services, and tools. As cyberinfrastructures, SDIs are similar to other infrastructures, such as water supplies and transportation networks, since they play fundamenta...

From 11.05.04 to 14.05.04, the Dagstuhl Seminar 04201 Content Distribution Infrastructures was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar resul...
