    This document joins deliverables D6.2 "Expansion of the SERIES database" and D6.3 "Updated version of SERIES database" of the SERA project. Maintenance and expansion of the SERIES database is one of the two main objectives of SERA work package 6 "Networking experimental seismic engineering databases (SERIES)". The actions taken to achieve this objective are described in the following and include the creation of the graphical user interface (GUI) and its user manual, the development of tools that assist in the creation of experimental data, and the modifications in the Data Access Portal (DAP) website and back-end. The installation manual and the user manual are given in AnnexesJRC.E.4-Safety and Security of Building

    Review of current SERIES and EPOS Databases

    Get PDF
    In a world-wide scale, collaborations in earthquake engineering lack a common interoperability framework, resulting in tedious and complex procedures to integrate data and results. Up to now, the most significant effort in Europe towards the interoperability of earthquake engineering experimental data was the SERIES project (Seismic Engineering Research Infrastructures for European Synergies) in the period 2009 - 2013. Global sharing of seismological data has been a long-lasting tradition tracing back to the beginning of the previous century. Recently, the ESFRI (European Strategic Forum for Research Infrastructures) initiative and the EPOS project (European Plate Observing System), provided a larger framework for the integration of all solid Earth science data into a single Pan-European e-infrastructure. Up to now, the two adjacent scientific disciplines, i.e. the earthquake engineering and seismology, have not interfaced their data structures, lacking an interoperable data-sharing structure. However, there is need to increase the interaction of the earthquake engineering and seismology communities by integrating the most important databanks and related informatics services in Europe, i.e. SERIES and EPOS. This deliverable presents a review of the current SERIES and EPOS systems: the main features of the two are discussed, focusing on their architecture, content, databases, functionality and access portals. It is noted that aiming to a better knowledge of the EPOS and SERIES projects, the deliverable needed to review also two approaches for data sharing and integration (governance, architecture, collaboration), and not be only limited to a review of current SERIES and EPOS databases. The review presented in the deliverable will serve as the basis for the future roadmap for integration of earthquake engineering and seismological data and informatics services that will support the needs of the two research communities and beyond.JRC.E.4-Safety and Security of Building

    Classical Simulation of Relativistic Quantum Mechanics in Periodic Optical Structures

    Full text link
    Spatial and/or temporal propagation of light waves in periodic optical structures offers a rather unique possibility to realize in a purely classical setting the optical analogues of a wide variety of quantum phenomena rooted in relativistic wave equations. In this work a brief overview of a few optical analogues of relativistic quantum phenomena, based on either spatial light transport in engineered photonic lattices or on temporal pulse propagation in Bragg grating structures, is presented. Examples include spatial and temporal photonic analogues of the Zitterbewegung of a relativistic electron, Klein tunneling, vacuum decay and pair-production, the Dirac oscillator, the relativistic Kronig-Penney model, and optical realizations of non-Hermitian extensions of relativistic wave equations.Comment: review article (invited), 14 pages, 7 figures, 105 reference

    The integration of earthquake engineering resources

    No full text
    Earthquake engineering is increasingly focusing on large international collaborations to address complex problems. Recent computing advances have greatly contributed to the way scientific collaborations are conducted, where web-based solutions are an emerging trend to manage and present results to the scientific community and the general public. However, collaborations in earthquake engineering lack a common interoperability framework, resulting in tedious and complex processes to integrate results, which cannot be efficiently used by third-party institutions. The work described in this thesis applies novel computing techniques to enable the interoperability of earthquake engineering resources, by integrating data, distributed simulation services and laboratory facilities. This integration focuses on distributed approaches rather than centralised solutions, and has been materialised in a platform called Celestina, that supports the integration of hazard mitigation resources. The prototype of Celestina has been implemented and validated within the context of two of the current largest earthquake engineering networks, the SERIES network in Europe and the NEES network in the USA. It has been divided into three sub-systems to address different problems: (i) Celestina Data, to develop best methods to define, store, integrate and share earthquake engineering experimental data. Celestina Data uses a novel approach based on Semantic Web technologies, and it has accomplished the first data integration between earthquake engineering institutions from the United States and Europe by means of a formalised infrastructure. (ii) Celestina Tools, to research applications that can be implemented on top of the data integration, in order to provide a practical benefit for the end user. (iii) Celestina Simulations, to create the most efficient methods to integrate distributed testing software and to support the planning, definition and execution of the experimental workflow from a high-level perspective. Celestina Simulations has been implemented and validated by conducting distributed simulations between the Universities of Oxford and Kassel. Such validation has demonstrated the feasibility to conduct both flexible, general-purpose and high performance simulations under the framework. Celestina has enabled global analysis of data requirements for the whole community, the definition of global policies for data authorship, curation and preservation, more efficient use of efforts and funding, more accurate decision support systems and more efficient sharing and evaluation of data results in scientific articles.</p

    Next directions in experimental data for seismic hazard mitigation

    Data are one of the main assets of earthquake engineering. Laboratory experiments can be extremely expensive and time consuming to replicate and, therefore, long-term preservation of experimental data and sharing the data with users has become one of the disciplinary priorities. There is a growing demand for international partnerships, which creates a need for data sharing, in an attempt to maximise research impact and to tackle experimental set-ups that could not be realised otherwise. However, there is a patent lack of interoperability between the institutions forming the earthquake engineering community, which inhibits efficient collaboration between them. In this paper, we discuss a vision about the directions that experimental data should take in the coming years, focusing on two aspects: enhanced international collaborations and implementation of open data access. We also describe the progress that has been made towards this vision, by establishing an open platform for the integration of earthquake hazard mitigation resources called Celestina. Celestina is supported by Semantic Web technologies, and uses an ontology as its integration data model. A prototype of the platform has been developed and tested between NEES (Purdue University, in the US), the University of Oxford (in UK) and EUCENTRE (in Italy), and a small proof of concept has enabled integrated experimental data from Oxford and EUCENTRE through the NEES cyberenvironment. This demonstration provides an example which has the potential to catalyze a new generation of research progress enabled by international data sharing

    The process and future of data integration within the European earthquake engineering laboratories

    In common with many scientific disciplines, earthquake engineering research is increasingly focusing on large international collaborations to address complex problems. Data integration is a key requirement to facilitate joint research efforts and to improve experimental outcomes. We present the development and implementation of a novel virtual database linking twenty two leading European earthquake engineering research institutions, making data integration possible at a European level without the need for a large, centralised repository. We describe the importance of establishing appropriate work methodologies to succeed in a distributed and highly heterogeneous work environment involving many dispersed institutions. We conclude by considering the future of earthquake engineering data integration, highlighting Semantic Web technologies as the main technological foundation to lead this integration.JRC.G.4-European laboratory for structural assessmen
