Soft sensor technology has been increasingly used in indus- try. Its importance is magnified when the process variable to be estimated is key to control and monitoring processes and the respective sensor ei- ther has a high probability of failure or is unreliable due to harsh environ- ment conditions. This is the case for permanent downhole gauge (PDG) sensors in the oil and gas industry, which measure pressure and tempera- ture in deepwater oil wells. In this paper, historical data obtained from an actual offshore oil well is used to build a black box model that estimates the PDG downhole pressure from platform variables, using Echo State Networks (ESNs), which are a class of recurrent networks with power- ful modeling capabilities. These networks, differently from other neural networks models used by most soft sensors in literature, can model the nonlinear dynamical properties present in the noisy real-world data by using a two-layer structure with efficient training: a recurrent nonlinear layer with fixed randomly generated weights and a linear adaptive read- out output layer. Experimental results show that ESNs are a promising technique to model soft sensors in an industrial setting. [less ▲]

Nul n’ignore la grande érudition d’Umberto Eco ni sa curiosité ouvrant son esprit aux plus vastes horizons. C’est pour cette raison que je me suis intéressée aux jeux d’échos qui résonnent dans son œuvre, tout comme à ceux qui peuplent les créations artistiques qui lui rendent hommage. Qu’il s’agisse de littérature, de cinéma, de linguistique, entre autres domaines, les champs qu’explore Eco se construisent en réseaux qui montrent quel prix il a attaché aux œuvres ouvertes. Ce constat me permettra d’organiser ma conférence-projection autour de la question de l’intertextualité (au sens large), en prenant l’exemple du roman Le Nom de la rose, afin de nous diriger en amont vers les Fictions de Borges et en aval vers l’adaptation cinématographique de ce « polar » médiéval qu’a réalisée Annaud.

Based on the analysis of a large corpus of tweets related to the First World War on the one hand and links contained in these tweets on the other hand, we question the ways activities of Twitter accounts show an appropriation of the Centenary. We hypothesize that the "Morts pour la France" database is currently emerging as a "lieu de mémoire". [less ▲]

Die beachtliche Tätigkeit des Echternacher Skriptoriums im 11. Jh. und die daraus hervorgegangenen kunsthistorisch bedeutenden Prachthandschriften machten Echternach berühmt. Die historisch nicht weniger wertvollen Handschriften des 12. Jhs., wie die für den klostereigenen Gebetsdienst angelegten Nekrologien sind hingegen weitestgehend unbekannt. Anhand einer kritischen Edition des Echternacher Martyrolog-Nekrologs aus dem 12. Jahrhundert soll die vorliegende Arbeit eine Forschungslücke im Bereich der Echternacher Memorialtradition schließen und den Grundstein für weiterführende Studien zu der Memoria und der Selbstdarstellung der Willibrordabtei legen. Unterschiedliche methodische Ansätze erlauben es, die Echternacher Memorialtradition aus unterschiedlichen Blickwinkeln zu erfassen und darzustellen. Anhand der kodikologischen Untersuchung der Handschrift und der paläographischen und prosopographischen Analysen konnte der Anlagezeitpunkt der Handschrift und die Frage nach einer konventseigenen Vorlage beantwortet werden. Die engen Verbindungen zum Trierer Kloster Sankt Maximin, die sich nicht nur auf das Gebetsgedenken beschränken, werden neu beleuchtet. Die inhaltliche Verbindung zwischen Martyrolog und Nekrolog eröffnet zwei Interpretationsebenen: die Bedeutung des Gebetsgedenken für das Seelenheil der Verstorbenen und für die Beständigkeit des Reiches. Die Abtei Echternach baute sich ein dichtes Netzwerk an Gedenkbeziehungen auf, die nur vor dem Hintergrund der politisch-religiösen Entwicklungen zwischen dem 10. und dem 12. Jahrhundert verstanden werden können. Dieses Beziehungsgeflecht verdeutlicht das wachsende historische Selbstbildnis der Abtei: eine traditionsreiche Gemeinschaft verankert in der Frühzeit ihrer Gründung und im Reich. Das Bild einer etablierten Reichsabtei, die dem Herrscher treu verbunden ist, festigt sich in der Zeit zwischen dem 10. und dem 12. Jh., wo es seinen Niederschlag im Martyrolog-Nekrolog, dem schriftlichen Gedächtnis der Abtei findet. [less ▲]

Models@Runtime aims at taming the complexity of software dynamic adaptation by pushing further the idea of reflection and considering the reflection layer as a first-class modeling space. A natural approach to Models@Runtime is to use MDE techniques, in particular those based on the Eclipse Modeling Framework. EMF provides facilities for building DSLs and tools based on a structured data model, with tight integration with the Eclipse IDE. EMF has rapidly become the defacto standard in the MDE community and has also been adopted for building Models@Runtime platforms. For example, Frascati (implementing the Service Component Architecture standard) uses EMF for the design and runtime tooling of its architecture description language. However, EMF has primarily been thought to support design-time activities. This paper highlights specific Models@Runtime requirements, discusses the benefits and limitations of EMF in this context, and presents an alternative implementation to meet these requirements.

This contribution presents the joint research project Econ4SD – Eco-construction for sustainable development which investigates at the University of Luxembourg various aspects of sustainable design, construction and operation to support a resource-efficient circular economy in the construction sector. In this context the fundamental approach of Design for deconstruction assumes a central role and is being discussed together with the complementary concept of Material banks and their digital twinning at the level of components, buildings and markets.

Alors que la nature a toujours eu bonne presse dans les livres pour enfants et pour adolescents, une préoccupation, voire un sentiment d’urgence, s’immisce, dès la seconde moitié du XXe siècle, dans les écrits et les images représentant animaux, végétaux et environnements à destination des jeunes lecteurs. Loin de simplifier la pensée écologique, des auteurs rendent sensible la complexité de l’interaction entre l’humain et la nature en créant des images, en inventant des histoires et en réinventant les formes pour les raconter. Qu’apporte cette littérature à la jeunesse ? N’est-elle là que pour transmettre le fameux message « écolo » de l’adulte à ceux qui grandissent ? [less ▲]
