In the present paper, a model-based fault/attack tolerant scheme is proposed to cope with cyber-threats on Cyber-Physicals Systems. A common scheme based on observers is designed and a state feedback control based on an aperiodic event-triggered framework is given with control synthesis and condition on the switching time. Classical fault tolerant control with Bi-linear Matrix Inequality () approaches are used to achieve novel and better security strategy based on an event-triggered control implementation. The purpose of using the event-based implementation would be to reduce (limit) the total number of transmissions to only instances when the networked control system (NCS) needs attention. Simulation results on a real-time laboratory three tank system are given to show the attack-tolerant control ability despite data deception attacks on both actuators and sensors. A detection/isolation scheme based on residual observers bank is also proposed. [less ▲]

From the theory of compensatory Internet use, escapism through videogames may constitute a coping strategy that is sometimes helpful but, in some cases, maladaptive. Yet, evidence supporting this view has, to date, been gathered only through the use of explicit self-reported questionnaires, which are known to be biased. Accordingly, the aim of the current study was to test whether the escapism motive is related to a preference for the virtual environment. Method. A laboratory task that allowed the measurement of implicit attitudes, namely, the Affect Misattribution Procedure was created with stimuli from real world and videogames. The task was administered online with a series of questionnaire and completed by 273 online gamers from the community. Results. The results showed that participants had more positive attitudes toward pictures depicting virtual environments than toward those depicting real environments. Furthermore, those participants who frequently used videogames to escape real life and were highly engaged in video gaming had a more pronounced positive implicit attitude toward the virtual environment. Discussion. This study contributes to a better understanding of the psychological processes underlying escapism in videogames and calls for a refinement of the escapism construct, which can be related to both problematic (i.e., potential coping strategy) and nonproblematic patterns of videogame use. Among the limitations, it should be noted that the selection of stimuli related to videogames is restricted to one genre of game, and that the participants’ environment could not be controlled due to the online design.

This paper historicizes “rigour”, discipline” and “systematic” as inventions of a certain rational spirit of Enlightenment that was radicalized during the 19th century. These terms acquired temporary value in a transition during the 19th century when a culture of research was established within a modern episteme. Beginning in the 20th century, this development was perceived as problematic, triggering criticism from philosophy and the arts, and even within the sciences. “Discipline”, “rigour” and “systematic” have changed meanings over time, and recent contributions from Digital Humanities are promising for a renewed critical debate about rigour in research. Both digital humanities and quantitative research deal with big data sets aimed at providing a large-scale analysis. However, unlike most quantitative research, digital humanities explore uncertainties as their main focus. Attention to the human-machine collaboration has led to more expansive thinking in scientific research. Digital humanities go further by advancing a metaperspective that deals with the material hermeneutics of data accumulation itself. [less ▲]

The automatic identification of core concepts addressed by a learning resource is an important task in favor of organizing content for educational purposes and for the next generation of learner support systems. We present a set of strategies for core concept identification on the basis of a semantic representation built using the open and available knowledge in the so-called Knowledge Graphs (KGs). Different unsupervised weighting strategies, as well as a supervised method that operates on the semantic representation, were implemented for core concept identification. In order to test the effectiveness of the proposed strategies, a human-expert annotated dataset of 96 learning resources extracted from MOOCs was built. In our experiments, we show the capacity of the semantic representation for the core-concept identification task as well as the superiority of the supervised method. [less ▲]

Concrete-steel composite structures are very efficient in carrying high loads as they combine benefits of both materials concrete and steel. The combination of them can significantly improve the strength of the composite structure by taking advantage of high compression resistance of concrete and high strength of steel in tension. Recently, there has been renewed interest in the composite structures used in different forms, as beams, slabs, sandwich structures and columns and many methods of structural analyses were utilised. However, none of them was able to eliminate concrete material when it fractured. The presented work concerns circular composite columns CFST under eccentric compression. The principal objective of the project was to investigate a straightforward method based on a finite element analysis employed to estimate the load carrying capacity of columns. This study has also been set out to determine whether the Drucker-Prager material model of concrete without a crack capability could be used for analyses of the CFST columns with the additional elimination of the concrete material when concrete is damaged. The elaborated finite element model was verified with existing test data from the literature. The findings show that the correlation between the test results and the numerical analysis was excellent confirming the feasibility of usage of the proposed method for the assessment of complex cases of the CFST columns. A new part of the work is the employment of a death element feature to eliminate concrete material, which theoretically is not taking any load after reaching its tensile strength. A criterion to eliminate elements from the model is the maximum principal stress greater than tensile strength. The obtained results are excellent; the established goal was met entirely. [less ▲]

The UPcycling using Additive Manufacturing (UpAM) project seeks to introduce an innovative educational and interactive framework to demonstrate the benefits of upcycling so that any individual can produce their own products using recycled raw materials. For years, societies have been aware that the unlimited consumption of products is unavoidably intertwined with the unlimited production of waste. This is exactly why scientists and researchers have been trying to find alternative and meaningful solutions to the Linear Economy model, a model that dictates a specific sequence of events: extracting raw materials, manufacturing products, consuming and discarding these products. Looking beyond that ‘take, make, dispose’ approach, it was in 1989 that the notion of Circular Economy (CE) was first proposed by Pearce and Turner; a concept that is restorative and regenerative and that involves reusing products, repairing, recycling and upcycling. Therefore, the core element of this innovative and environmentally-friendly model is to rely on system-wide innovative processes in order to redefine products, services and, most importantly, our way of thinking, to design waste out, thus allowing a profound transition to renewable energy sources [less ▲]

Avec l’armistice en novembre 1918, la région de Malmedy s’apprête à sortir de la guerre. Comme dans de nombreuses autres régions européennes, le passage de la guerre à la paix ne s’identifie pas au silence des canons et des armes, mais prend la forme d’un processus lent. Toutefois, la région devient également l’objet des négociations diplomatiques qui commencent à Versailles au printemps 1919. Finalement, Malmedy ne sortira pas seulement de la guerre, mais aussi de l’Allemagne pour être rattachée à la Belgique. La conférence se propose de jeter un regard serré sur les deux ans qui séparent l’armistice et l’aval du transfert de souveraineté par la Société des Nations en septembre 1920. Sur base de publications récentes, elle se livre à une analyse à plusieurs niveaux : vie quotidienne de la population sous l’Occupation britannique, arrivée des troupes belges en été 1919, débuts du Gouvernement Baltia en janvier 1920 et « consultation populaire » y trouveront tout autant leur place que les regards des autorités belges et les regards étrangers sur l’espace frontalier belgo-allemand durant cette période.

A la suite du Traité de Versailles, la Belgique s’agrandit de quelques 60.000 habitants et de 1.000 km², en annexant les deux Kreise allemands d’Eupen et de Malmedy. Tandis que le premier est largement germanophone, le deuxième compte env. 10.000 franco- ou wallonophones autour de Malmedy. La conférence retrace d’abord les origines de cette annexion, des projets d’expansion territoriale, conçus pendant la guerre, aux négociations du Traité de Versailles. Un accent sera mis sur l’élaboration de l’article 34 de ce traité, qui prévoit une forme de « consultation populaire » unique en son genre et dont l’application a lourdement hypothéqué l’intégration des « Nouveaux Belges » dans leur nouvelle patrie. La deuxième partie de la conférence est consacrée au régime de transition que la Belgique y instaure en 1920. Ce gouvernement provisoire placé sous le Haut Commissaire Herman Baltia est alors en charge de l’intégration des habitants dans l’Etat belge. Comment peut-on « gagner les cœurs et les esprits » d’une population qui, encore en 1918, ne se serait jamais vue devenir belge ? La troisième partie traite de la loi d’intégration du 6 mars 1925 qui met fin au régime de transition et intègre les trois cantons d’Eupen-Malmedy-Saint-Vith dans l’arrondissement de Verviers et la province de Liège. Dans ce contexte, des propositions voient le jour qui seront encore d’actualité lors des débats sur l’autonomie culturelle dans les années 1960. La recherche scientifique a montré depuis longtemps que la politique d’intégration belge menée dans la région pendant l’entre-deux-guerres a été un échec – révélé au plus tard en mai 1940. La conférence jette une nouvelle lumière sur les débuts de celle-ci et sur sa perception par la population et les acteurs politiques. [less ▲]

Cette intervention se propose d'étudier les politiques institutionnelles d'archivage du Web à plusieurs échelles, depuis les aspects organisationnels propres à une institution jusqu'aux enjeux de gouvernance globaux et internationaux. Il s'agira aussi d'étudier en quoi "des formes spécifiques de pouvoir et d'autorité" (Winner, 198 121) peuvent être décelées au sein des processus comme des artefacts produits. Une réflexion sur les périmètres de sélection des contenus (et leurs éventuels biais), la curation à la fois humaine et technique, l'équilibre entre nouvelles formes d'action et cadres imposés (par exemple dans le cadre du dépôt légal) permettra de dévoiler les multiples strates politiques à l'oeuvre dans l'archivage du Web.
