Pre-service teachers’ experiences with a digital examination design: The inter-relation between continuity and change in an institutional context
2019
AbstractThis article reports a study of a full-scale digital examination in a five-year master program of teacher education in Norway. The innovative design involves observing a video case based on an authentic classroom situation and analysing the case in light of educational theory and subject content knowledge. All parts of this format are to be solved on a computer with Internet access. The study is centred on the pre-service teachers’ experiences of this open-ended and unfamiliar testing format. More specifically, the intention has been to analyse (a) what kinds of preparations they engaged in; (b) how they solved tasks during the examination; (c) their reflections on this mode of exam…
Hyperreal positioning and cross-channel strategy of cultural sites: towards the construction of a metaexperience for the visitor?
2019
International audience; Immersive concepts, games, participation, digitization ... many concepts that cultural institutions adopt to enlarge their audiences. Through these tools, reality, imagination and simulation, are mixing to give rise to a hyperreal offer. With the development of digital and multiple consumption behaviors, the analysis of the coherence between physical and digital channels is now a major challenge for museums. Based on 16 French museums case studies, this research proposes some solutions to the articulation of these channels in order to propose a coherent global experience.
Towards a pragmatics of weblogs
2007
The weblog has emerged as one of the most dynamic means of Internet communication, in which users upload whatever piece of information they consider might arouse other users’ attention. Many articles and books have already addressed this new communicative phenomenon, but so far the weblog has not been addressed in purely cognitive-pragmatic terms. This article provides a first relevance-theoretic pragmatic analysis of the discourse of weblogs and their communicative qualities and limitations. El weblog ha surgido como una de las formas más dinámicas de comunicación, en la cual los usuarios de Internet “cuelgan” cualquier información que consideran que puede atraer la atención de otros usuar…
La « mise en jeu » de la santé par la mondialisation
2003
A travers de nombreux exemples, Jean-Claude Fritz illustre le paradoxe auquel le monde se trouve aujourd’hui confronte : une richesse et un niveau de developpement sans precedent dans l’histoire, auxquels s’opposent aggravation des inegalites, violences, degradation de l’environnement... qui marginalisent une partie de l’humanite. Le changement est non seulement necessaire mais possible.
Speckle Interferometry Analysis of Full-bending Behavior of GFRP Pultruded Material
2016
Abstract The use of Glass Fiber Reinforced Polymer materials (GFRP) has increased in the last years even among civil structural engineering due to their high specific strength, lightweight and excellent corrosion resistance. With application of the pultrusion method, the manufacture of large-scale profiles with various cross-section forms became potentially possible with relatively low costs. Usually two different technological approaches are available to realize the element: in the first one a mat-roving-mat sequence is adopted, in the second one only roving is present. Continuous filament mat (CFM, fibers distributed randomly in all directions) is often used to build up laminate thickness…
Experimental Study Regarding PA and PE Sheets on Single Point Incremental Forming Process
2021
The present paper aims to present an experimental study on the behaviour of PA and PE sheets during the single point incremental forming. Due to the fact that the purpose of this research is to study the behaviour of PA and PE sheets during the single point incremental process both in terms of process forces and in terms of major and minor strain and thickness reduction, a Kuka Kr210 robot was chosen as an alternative to using a universal milling machine. The specimens were made of 3 mm PA and PE sheets. The size of the sheets was 250 mm x 250 mm. The forces measured on the three directions of the coordinate axes were compared. To measure the major strain, minor strain and thickness reducti…
On the use of Digital Image Correlation (DIC) for evaluating the tensile behaviour of BFRCM strips
2019
Abstract. Fibre Reinforced Cementitious Matrix (FRCM) composites are becoming largely adopted for retrofitting masonry structures. These materials offer several advantages in comparison to Fibre Reinforced Polymer (FRP) composites, such as good resistance to fire and high temperatures, vapour permeability, possibility to be applied on wet surfaces, higher compatibility with the masonry substrate. However, the tensile behavior of FRCM materials is more complex compared to FRP composites, due to the limited tensile strength of the cement-based matrix. For this reason, FRCM materials require appropriate tensile characterization and, in this context, the use of non-conventional measurement syst…
Mechanical Behavior of Steel Fiber-Reinforced Concrete Beams Bonded with External Carbon Fiber Sheets
2017
This study investigates the mechanical behavior of steel fiber-reinforced concrete (SFRC) beams internally reinforced with steel bars and externally bonded with carbon fiber-reinforced polymer (CFRP) sheets fixed by adhesive and hybrid jointing techniques. In particular, attention is paid to the load resistance and failure modes of composite beams. The steel fibers were used to avoiding the rip-off failure of the concrete cover. The CFRP sheets were fixed to the concrete surface by epoxy adhesive as well as combined with various configurations of small-diameter steel pins for mechanical fastening to form a hybrid connection. Such hybrid jointing techniques were found to be particularly adva…
In Vitro Measurement of Strain Localization Preceding Dissection of the Aortic Wall Subjected to Radial Tension
2020
AbstractBackgroundAortic dissection (AD) is a common pathology and challenging clinical problem. A better understanding of the biomechanical effects preceding its initiation is essential for predicting adverse events on a patient-specific basis. Moreover, the predictability of patient-specific biomechanics-based computational models is hampered by uncertainty about boundary conditions and material properties.ObjectivePredisposition of thoracic aortic aneurysms (TAA) to ADs can be related to the degradation of biomechanically important constituents in the aortic wall of TAAs. The goal of the present study is to develop a new methodology to measure strain fields in aortic tissues subjected to…
