An integrated identity verification system for mobile terminals
2005
PurposeTo report the work on the design of an integrated identity verification system architecture aimed at approaching high verification accuracy, continuous security, and user‐friendliness.Design/methodology/approachThe reported research corresponds to the building process in the design science research paradigm. The requirements to an identity verification system are defined and used in the selection of architecture components. Furthermore, various issues affecting the suitability of component distribution between a terminal and a remote server are considered.FindingsIn order to meet the stated requirements, in the proposed architecture static and dynamic identity verification is combine…
United We Stand: The Recognition of Joint Degrees
2003
Joint degrees are awarded on the basis of completion of a study program established and provided jointly by two or more higher education institutions, normally located in different countries. They therefore normally require students to take a part of their degree abroad and are a potentially important instrument for increasing academic mobility and internationalizing higher education in Europe, which are among the key goals of the Bologna Process. A recent study by one of the authors, Andrejs Rauhvargers, undertaken for the European University Association (EUA), considers this increasingly important element of higher education that, however, is hampered by inadequate recognition across bor…
MASPEGHI 2004 Mechanisms for Speialization, Generalization and Inheritance
2005
Rapport de Recherche Projet OCL, N° I3S/RR-2004-15-FR; International audience; MASPEGHI 2004 is the third edition of the MASPEGHI workshop. This year the organizers of both the ECOOP 2002 Inheritance Workshop and MASPEGHI 2003 came together to enlarge the scope of the workshop and to address new challenges. We succeeded in gathering a diverse group of researchers and practitioners interested in mechanisms for managing specialization and generalization of programming language components. The workshop contained a series of presentations with discussions as well as group work, and the interplay between the more than 22 highly skilled and inspiring people from many different communities gave ri…
Distributed Data Collection for the ATLAS EventIndex
2015
The ATLAS EventIndex contains records of all events processed by ATLAS, in all processing stages. These records include the references to the files containing each event (the GUID of the file) and the internal “pointer” to each event in the file. This information is collected by all jobs that run at Tier-0 or on the Grid and process ATLAS events. Each job produces a snippet of information for each permanent output file. This information is packed and transferred to a central broker at CERN using an ActiveMQ messaging system, and then is unpacked, sorted and reformatted in order to be stored and catalogued into a central Hadoop server. This contribution describes in detail the Producer/Consu…
ATLAS operations in the GridKa T1/T2 Cloud
2011
The ATLAS GridKa cloud consists of the GridKa Tier1 centre and 12 Tier2 sites from five countries associated to it. Over the last years a well defined and tested operation model evolved. Several core cloud services need to be operated and closely monitored: distributed data management, involving data replication, deletion and consistency checks; support for ATLAS production activities, which includes Monte Carlo simulation, reprocessing and pilot factory operation; continuous checks of data availability and performance for user analysis; software installation and database setup. Of crucial importance is good communication between sites, operations team and ATLAS as well as efficient cloud l…
Analysis of a Station Black-Out transient in SMR by using the TRACE and RELAP5 code
2014
The present paper deals with the investigation of the evolution and consequences of a Station Black-Out (SBO) initiating event transient in the SPES3 facility [1]. This facility is an integral simulator of a small modular reactor being built at the SIET laboratories, in the framework of the R&D program on nuclear fission funded by the Italian Ministry of Economic Development and led by ENEA. The SBO transient will be simulated by using the RELAP5 and TRACE nodalizations of the SPES3 facility. Moreover, the analysis will contribute to study the differences on the code predictions considering the different modelling approach with one and/or three-dimensional components and to compare the capa…
The EU-Ukraine Association Agreement prior to the Vilnius Eastern Partnership Summit
2014
Abstract This paper seeks to explore how the EU policy on Ukraine evolved in the run-up to the Eastern Partnership Summit in Vilnius in November 2013. In particular, it looks into the preparations leading to the signature of the EU-Ukraine Association Agreement. Thereby it contributes to better understanding of the EU policy debate related to the associated negotiations with the Eastern Partnership countries. Prior to the Vilnius Summit there were high expectations that signature of the EU-Ukraine Association Agreement would become a key deliverable of the summit. After the EU had postponed the signing of the agreement due to Ukraine’s backsliding in democracy for several times, the process…
Minimum theorems for displacement and plastic strain rate histories in structural elastoplasticity
1975
The finite element method approach is used to obtain formulations of analysis problems relative to elastic-plastic structures when subjected to prescribed programmes of loads, and under the restrictive hypotheses:a) the yielding surfaces are piecewise linearized, andb) the plastic flow-laws are supposed to be of holonomic type within a single “finite” time interval. For mulations are given as linear complementarity problems and quadratic programming problems: one pair of formulations in terms of velocity and plastic multiplier rate histories, and another pair in terms of plastic multiplier rate histories only. The solutions are shown to be characterized by two minimum principles for displac…
Virtual Reality and Psychopathology
2009
Progress in the development of Virtual Reality (VR) is faster than has been forecast, which makes deep reflection on its potential uses and abuses absolutely necessary. The current article focuses on the analysis of some of the applications and implications of VR on psychopathology. It is obvious that they could be many, but we are only focusing on: (a) VR as a model to answer some central questions that traditionally have intrigued psychopathologists; and (b) VR and possible psychopathological experiences. We believe that VR has the potential of becoming a tool that will allow psychopathology to challenge and modify theoretical positions already established, and to pose new ones. This new …
