iRODS: Setup and Use of a National Data Management System in the French NGI

International audienceScientific communities acquire more and more data and the need for tracking and managing of data in a simple framework is essential for providing scientific results in a timely manner. In France, several laboratories have gained experience with iRODS (Rule-Oriented Data Management System) which acts as a data grid by providing a transparent access to data which can be spread over different physical locations on heterogeneous storage technologies. Five of these laboratories (CCIN2P3 in Villeurbanne, IPHC in Strasbourg, LPSC in Grenoble, MCIA and CBiB in Bordeaux) have joined their efforts by providing a single iRODS infrastructure in the framework of the French NGI. This system is intended for hosting users from any scientific domain in need of storage or data management, and with little experience or dedicated personnel in the domain of data management. In this contribution, an overview of the iRODS features is given, followed by the description of the national iRODS instance. The hosting of end users and the early adopter experience are also presented, as well as the development of the project towards building a national pool of expertise for the use and the administration of the iRODS product

Integrated roof wind energy system

Wind is an attractive renewable source of energy. Recent innovations in research and design have reduced to a few alternatives with limited impact on residential construction. Cost effective solutions have been found at larger scale, but storage and delivery of energy to the actual location it is used, remain a critical issue. The Integrated Roof Wind Energy System is designed to overcome the current issues of urban and larger scale renewable energy system. The system is built up by an axial array of skewed shaped funnels that make use of the Venturi Effect to accelerate the wind flow. This inventive use of shape and geometry leads to a converging air capturing inlet to create high wind mass flow and velocity toward a vertical-axis wind turbine in the top of the roof for generation of a relatively high amount of energy. The methods used in this overview of studies include an array of tools from analytical modelling, PIV wind tunnel testing, and CFD simulation studies. The results define the main design parameters for an efficient system, and show the potential for the generation of high amounts of renewable energy with a novel and effective system suited for the built environment
