Established analysis methods apply to whole operational systems, taking a necessarily holistic view of security, but this makes them difficult to integrate into the design process for service-based applications, where design and implementation is independent of operational deployment. However, the most costly mistakes

This paper draws on the experience of developing requirements for a grid- based project, the Distributed Aircraft Maintenance Environment

This work is central to the development of distributed intelligent control systems that are inherently adaptable and dynamically reconfigurable. The approach that is used takes advantage of distributed artificial intelligence at the planning and control levels to

This paper describes new functionality in the CARMEN VL: an interactive publications repository. This new facility allows users to link data and software to publications. This enables other users to examine data and software associated with the publication and execute the associated software within the VL using the same data as the authors used in the publication. The cloud-based architecture and SaaS (Software as a Service) framework allows vast data sets to be uploaded and analysed using software services. Thus, this new interactive publications facility allows others to build on research results through reuse. This aligns with recent developments by funding agencies, institutions, and publishers with a move to open access research. Open access provides reproducibility and verification of research resources and results. Publications and their associated data and software will be assured of long-term preservation and curation in the repository. Further, analysing research data and the evaluations described in publications frequently requires a number of execution stages many of which are iterative. The VL provides a scientific workflow environment to combine software services into a processing tree. These workflows can also be associated with publications and executed by users. The VL also provides a secure environment where users can decide the access rights for each resource to ensure copyright and privacy restrictions are met.

It currently supports remote analysis of vibration and performance data by various geographically dispersed users: local engineers and remote experts. The diagnosis environment is built around a workflow system, and an extensive set of data analysis tools and services, which can provide automated diagnosis for known conditions. Where automated diagnosis is not possible DAME provides remote experts with a collaborative and interactive diagnosis and analysis environment.

Large, complex datasets are typical, with a heterogeneous range of data and code formats. The CARMEN project (http://www.carmen.org.uk/) aims to enable broad sharing or resources, through provision of a secure, online environment for data analysis, and curation of data, analysis code and experimental protocols.
