The educational technology support team of the city of Luxembourg deployed 60 iPads, in a pilot phase during the school year 2014-2015, in around 120 Kindergarten classes. In order to assess whether this deployment was well received by teachers and whether it was worth extending it, we did an exploratory survey study that asked Kindergarten teachers about their reactions to the provided iPads. Moreover, we wanted to contribute to the existing body of research on enabling and hindering factors for the integration of ICT in education (Ertmer, 2005; Pelgrum, 2011). We did send out an email to about 210 Kindergarten teachers inviting them to participate in our study and answer various questions about their use or not of the provided iPads. A mix of open and closed questions were used. We first asked them whether they had used the iPads or not and depending on their answers they received a slightly different version of our survey. Both groups of respondents were asked to answer some questions not directly linked to the use of iPads in education: their gender, their age, the length of their work experience, how many children they have in their class, how competent they feel with using digital tools, what digital tools they use privately and for what purposes they use them, what digital tools (other than iPads) they use in their classes and for what purposes they use them, what they consider to be good teaching in Kindergarten. Those who said they had indeed used the iPads were then asked how they had prepared themselves before using the iPads in class, why and for what purposes and for which learning & teaching activities they had used them (Leclercq & Poumay 2005), what they had expected from their use, what problems, issues and challenges they had faced, if they would want to use them more / differently in the future, what they would need to wore more / better with iPads and whether they would be willing to offer professional development sessions to other teachers. Those who said they did not use the provided iPads were asked why they did not use the iPads, if they had thought about the use of iPads in education, if they had heard about it from colleagues, under which conditions they might consider to use them, how they would prepare themselves in case they would plan to use iPads in their class, if they wanted to visit colleagues and observe how they use them, for what purposes and activities they might want to use them, how they would use them, and what effects they would expect the iPads to have on their pupils and on their teaching. Overall, 91 teachers filled out the survey, 63 claiming they had (at least once) used the provided iPads in their class and 28 saying they never used them. Results will be presented at the conference and discussed in terms of teacher believes about the usefulness of tablets and digital technologies (Tondeur, Hermans, van Braak & Valcke, 2008), and more specifically how first-order and second-order barriers impact Kindergarten teachers decisions to integrate mobile ICT in their classrooms, or not (Lui & Pange, 2015).

Multilingual teaching and the promotion of multilingualism among students are important principles of the University of Luxembourg. For their implementation, a variety of e-learning resources are used, adapted to the needs of the learners. We will give an overview of new multimodal communication practices and methods used by learners in multilingual contexts which naturally lead teachers to rethink their approach and incorporate media into their teaching strategies. The hybrid nature of devices (computers, tablets, televisions, smartphones, paper, interactive whiteboards, etc.) and digital tools (document sharing platforms, online correction tools, interactive exercises, online learning programmes, dictionaries, video editing software, automatic pronunciation correction, etc.) offer a great potential to interactive and mobile teaching and learning. We will illustrate this potential by giving an example of how to develop text production competence in Chinese as a foreign language in a motivating way using the content management system Moodle. Our reflection aims at optimising the quality of language teaching both in and out of the classroom. [less ▲]

The use of simulation in the design of critical embedded systems

Les plate-formes virtuelles permettant de prédire par simulation numérique les performances deviennent peu à peu une réalité dans la conception des systèmes de contrôle les plus complexes et les plus contraints (automobile, aéronautique, contrôle de réseaux power-grid, etc). Dès les phases amont du cycle de conception, ces outils guident les concepteurs dans leurs choix de conception. Le premier objectif de cet exposé est de dresser un rapide panorama des modèles et techniques de simulation de l'embarqué critique: simulation du comportement fonctionnel (lois de contrôle), simulation "timing-accurate" des plate-formes d'exécution, de leur complémentarité et limites actuelles. Contrairement à des techniques mathématiques, la simulation ne fournit a priori aucune garantie sur la couverture de vérification et les situations pire-cas ("corner cases") ne sont pas nécessairement identifiées. Néanmoins la simulation est de plus en plus incontournable car les modèles analytiques ne sont généralement pas en mesure de capturer toute la complexité des systèmes réels. Le second objectif de cet exposé est d'identifier des bonnes pratiques méthodologiques pour l'utilisation de la simulation dans les systèmes critiques (ex: choix des temps de simulation et nombre d'expérimentations en fonction de caractéristiques structurelles des processus simulés, métriques de performances pour les événements rares, etc).

An overview of the use of the discrete Sugeno integral as either an aggregation tool or a preference functional is presented in the qualitative framework of two decision paradigms: multi-criteria decision-making and decision-making under uncertainty. The parallelism between the representation theorems in both settings is stressed, even if a basic requirement like the idempotency of the aggregation scheme should be explicitely stated in multi-criteria decision-making, while its counterpart is implicit in decision under uncertainty by equating the utility of a constant act with the utility of its consequence. Important particular cases of Sugeno integrals such as prioritized minimum and maximum operators, their ordered versions, and Boolean max-min functions are studied. [less ▲]

AIMS: The Sideguard(R) stent (Cappella Medical Devices Ltd, Galway, Ireland), is a novel nitinol self-expanding dedicated bifurcation stent that flares proximally at the ostium of the side branch (SB) into a trumpet shape thereby achieving full ostial coverage. The aim of this study is to report the utility and limitations of this stent in patients undergoing treatment to bifurcation coronary lesions in a real-world setting. METHODS AND RESULTS: We prospectively identified 20 successive patients admitted over a 6-month period in whom there was significant SB disease and who were suitable for a bifurcation procedure. The Sideguard(R) stent was successfully used in all 20 cases including several that would have been technically difficult using conventional bifurcation techniques. We highlight use of this system using five illustrative cases that illustrate its utility and limitations in the treatment of bifurcation lesions. CONCLUSIONS: The Sideguard(R) stent can be used to treat complex bifurcation lesions in a straight forward manner and is not subject to the limitations associated with conventional bifurcation PCI techniques including jailing of the SB ostium and inability to fully cover/scaffold the ostium of the SB.

The aim of this paper is to apply both time- and frequency-domain-based approaches on real-life civil engineering structures and to assess their capability for damage detection. The methodology is based on Principal Component Analysis. The first structure is the Champangshiehl Bridge located in Luxembourg. Several damage levels were intentionally created by cutting a growing number of prestressed tendons and vibration data were acquired by the University of Luxembourg for each damaged state. The second example consists in reinforced and prestressed concrete panels. Successive damages were introduced in the panels by loading heavy weights and by cutting steel wires. The illustrations show different consequences in damage identification by the considered techniques [less ▲]
