Un software integrato per il sistema di scanning 3D IVVS dell'ENEA
No full textITER is a joint international research and development project that aims to demonstratethe scientific and technical feasibility of fusion power. The partners in the project arethe European Union (represented by EURATOM), Japan, the People´s Republic of China,India, the Republic of Korea, the Russian Federation and the USA. ITER will be constructedin Europe, at Cadarache in the South of France.A prototype of a laser In Vessel Viewing System was developed at ENEA laboratoriesin Frascati, which uses the amplitude modulated laser radar concept and it is conceivedto withstand the severe ITER conditions. The IVVS (In Vessel Viewing System) probe hasbeen designed and built to perform sub-millimetric three-dimensional images insideITER during maintenance procedure and it is based on an intrinsically radiation resistantconcept and architecture.CASPUR has developed the control/visualization software of the inspection system,which drives all the operations needed to perform an inspection: it is a graphical applicationthat starts an acquisition, performs the necessary data conversion to speedup theanalysis, archives and manages previous acquisitions, displays the reconstructed 3dscene, possibly comparing it with CAD data, while providing a range of image analysisand filtering tools
Un microscopio computazionale per lo studio di materiali innovativi per il fotovoltaico del futuro
No full textThe importance of using photovoltaics (PVs) to obtain clean and reliable energy hasbeen widely recognized. The scientific research on new PV materials is crucial to identifynew approaches to the concept of solar energy conversion and to increase the photonversionefficiency. Among the different approaches for PV, the quantum dot (QD) solarcell is one of the most promising. A single layer QD consists of a distribution ofnanocrystals embedded into an amorphous dielectric matrix. It is in principle possibleto affect the optoelectronic properties of QD layers by controlling the morphology ofthe nanograins. The complex atomic scale structure of such materials makes it quitedifficult to predict theoretically their optoelectronic properties. The theoretical challengeis two-fold; on the one hand, it is necessary to generate large scale atomistic models;on the other hand, the corresponding electronic properties must be computed over alarge number of atoms. While the first issue can be coped with large-scale moleculardynamics (MD) simulations, the second issue is a major computational bottleneck andit requires a class of advanced algorithms for the electronic structure calculations inwhich the computational workload scales linearly with the number of atoms. Within acollaboration among CASPUR and the SLACS (Sardinian Laboratory for Computationalmaterials science) we have implemented a new numerical method to investigate theoptoelectronic properties of silicon based QD layers. By using such a theoretical frameworkit is possible to assist the design of new efficient materials for PV
L'Università di Palermo ha scelto SURplus per il "governo" della Ricerca
Get PDFThe SURplus system has been recently acquired by the Università degli Studi of Palermo. Its most significant modules are already implemented: the WF (Work Flow) module for research projects management, the OA (Open Archive) module for research products management, and the BI (Business Intelligence) module that extracts and aggregates data from other system components to produce reports and statistics.Il sistema SURplus è stato acquisito dall'Università degli Studi di Palermo ed è già operativo nei suoi moduli più significativi: la gestione dei Progetti di Ricerca (modulo WF), il repository documentale di Ateneo basato su protocolli Open Archive (modulo OA) e la fruizione delle informazioni depositate negli archivi SURplus tramite reports e aggregazioni statistiche secondo una logica di Business Intelligence (modulo BI)

Almanacco SBN. News sui servizi CILEA per i Poli SBN: luglio-settembre 2008
Get PDFIn the quarter just ended, a lot of activities were carried out by CILEA team providing support to SBN poles. In particular, for the Polo USM, that is moving to Sebina OL, CILEA has made the first and important activity essential to the success of the process. Other important activities were carried out for the pole Unix client / server (two UNIMARC imports, both completed successfully) and the pole LO2 (customization of the OPAC for the Library of the Regional Council of Lombardia).Nel trimestre appena trascorso, diverse attività sono state svolte dai team CILEA che forniscono servizi ai poli SBN. In particolare, per il Polo USM (in procinto di passare a Sebina OL) il CILEA ha effettuato le prime operazioni indispensabili per il buon esito del passaggio. Altre attività importanti sono state svolte per i poli Unix client/server (due importazioni UNIMARC, entrambe conclusesi con successo) e per il polo LO2 (la personalizzazione dell’OPAC per la biblioteca del Consiglio regionale della Lombardia)

Il Conferencing Service Center del CASPUR: un integratore di servizi per la comunicazione avanzata
No full textIn the past years, several relevant projects in education and communication environmenthave contributed to develop and deploy modern videoconference infrastructures.In this framework CASPUR is playing a significant role, promoting and diffusing videoconferencetechnologies among its scientific partners and public administration. ConferencingService Center (CSC) is an innovative solution for integrating communicationand collaboration services, which promotes audio media as the main communicationchannel. A CSC user gets benefits from audio and data communications using a virtualroom for his meetings, eliminating or lowering barriers of distance and cost of travel.In this way, CSC helps public and private organizations to improve efficiency of internalcommunication and to reduce costs.The CSC web portal service is accessible at http://csc.caspur.it, seven days a weekand 24 hours a day; through this portal, conferencing services can be planned, managedand controlled. It encompasses the following features:• Accounts management in organizational hierarchy• Services booking and scheduling• On line service management• Activity analysis and reportsAs far services are concerned, CSC comprises the following ones:• Audioconferencing: accessing a virtual room using a telephone for voice and a pcor mobile device for data• VideoConferencing: IP/ISDN based virtual rooms for audio and video conference• Webconferencing: a java application built to share data in combination with oneof the two services above• Webstreaming: a customizable live or on demand video broadcastFurther any technological consideration, teleconferencing and related travels reductioncontributes to lower CO2 production.Ing.
