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…

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…

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…

Analysis of the IEEE 802.11e EDCA Under Statistical Traffic

2006

Many models have been proposed to analyze the performance of the IEEE 802.11 distributed coordination function (DCF) and the IEEE 802.11e enhanced distributed coordination function (EDCA) under saturation condition. To analyze DCF under statistical traffic, Foh and Zukerman introduce a model that uses Markovian Framework to compute the throughput and delay performance. In this paper, we analyze the protocol service time of EDCA mechanism and introduce a model to analyze EDCA under statistical traffic using Markovian Framework. Using this model, we analyze the throughput and delay performance of EDCA mechanism under statistical traffic.

Experimental realization of a Persistent Identifier Infrastructure stack for Named Data Networking

2015

The continuation of Persistent Identifier Infrastructures is crucial when next-generation Internet architectures based on Information-Centric Networking (ICN) arise. When moving to ICN, we must ensure the resolution of Persistent Identifiers (PID), such as the billions of Digital Object Identifiers (DOI) used today, to provide continued access to scientific literature and research data. It provides the base for the necessary transformations in the Handle System architecture and protocol for running a PID system on the Named Data Networking (NDN) architecture, which is a recent incarnation of ICN. Furthermore, it examines the PID-specific resolution access patterns, investigates the expected…

Dissensus, death and division

2009

The modeling of switching systems describing networks where death and duplication processes occur is described. A dissensus protocol, complementary to consensus protocol, is introduced and the convergence or divergence of the agents' state evolution is studied. We discuss some properties of the topology reached by the network when different rules of duplication and inheritance are implemented.

Study of a medium-size biological molecular association by means of a pair potential semiempirical approach: β-carboline-lumiflavin

1985

The molecular association between some substituted β-carbolines and a model flavin, lumiflavin, has been studied by means of a semiempirical approach proposed by Fraga based on a 1/R expansion of atom-atom pair potentials. Only stacked minima have been considered because of their possible biological interest. The calculations characterize 15 different minimum stacked conformations, most of them occurring in the complexes considered. The structural and energetic effects of 1–Me, 6–OH and 7–OH substituents of β-carboline are discussed. An equilibrium conformation involving geometric overlap between the pteridinic portion of flavin and the indole group of β-carboline is predicted to be the mos…

Predicting lorawan behavior. How machine learning can help

2020

Large scale deployments of Internet of Things (IoT) networks are becoming reality. From a technology perspective, a lot of information related to device parameters, channel states, network and application data are stored in databases and can be used for an extensive analysis to improve the functionality of IoT systems in terms of network performance and user services. LoRaWAN (Long Range Wide Area Network) is one of the emerging IoT technologies, with a simple protocol based on LoRa modulation. In this work, we discuss how machine learning approaches can be used to improve network performance (and if and how they can help). To this aim, we describe a methodology to process LoRaWAN packets a…
