Sentiment d’efficacité collective et professionnalisation en contexte d’apprentissage par projets
CESI a mis en place dans sa formation d’ingénieurs en alternance, en octobre 2015, l’Apprentissage Actif Par Projets (A2P2). L’apprentissage à l’école y est articulé autour de projets pluridisciplinaires à réaliser en groupes. Dans cet article nous proposons de questionner l’impact du sentiment d’efficacité collective et des situations pour le favoriser, dans le processus de […]

Modélisation multi-agent des systèmes industriels cyber-physiques fractals
Ce papier propose une modélisation basée sur des systèmes multi-agents pour la simulation d’un atelier de production considéré comme un système cyber-physique (CPS). Un système cyber-physique industriel, appelé en anglais « Cyber-Physical Production System » (CPPS), représente une composante fondamentale de l’industrie 4.0, qui influence fortement la manière de concevoir, piloter et superviser les ateliers de production […]

Identification of a cohesive zone model for cement paste-aggregate interface in a shear test
The development of tools, using a micromechanical approach, predicting the macroscopic behaviour of heterogeneous materials such as concrete, requires the knowledge of their microstructures (geometrical properties of phases), the behaviour of phases and the interaction laws between phases. This study is focused on a numerical modelling of a local shear test on a cement paste–aggregate […]

Shear-induced anisotropy in rough elastomer contact
True contact between randomly rough solids consists of myriad individual microjunctions. While their total area controls the adhesive friction force of the interface, other macroscopic features, including viscoelastic friction, wear, stiffness, and electric resistance, also strongly depend on the size and shape of individual microjunctions. We show that, in rough elastomer contacts, the shape of […]

Shear-induced contact area anisotropy explained by a fracture mechanics model
This paper gives a theoretical analysis for the fundamental problem of anisotropy induced by shear forces on an adhesive contact, discussing the experimental data of the companion Letter. We present a fracture mechanics model where two phenomenological mode-mixity functions are introduced to describe the weak coupling between modes I and II or I and III, […]

A dynamic programming-based maintenance model of offshore wind turbine considering logistic delay and weather condition
There are several challenges toward maintaining offshore wind turbines such as ensuring the intrinsic performance of the wind turbine, maximizing short- and long-term profits, and optimizing maintenance grouping. These criteria should be optimized in respect to several practical constraints. Moreover, issues such as decisionmaking in uncertain environments where reliability-oriented field data are insufficient and information […]

On the improvement of thermal comfort in indoor spaces conditioned by split-type systems
Conventional on/off-based control split-type appliances are widely used in classrooms and offices, in Brazil and in many other countries, due to their low cost and ease of installation. However, occupants often complain about thermal discomfort depending on their position within the conditioned space, especially in positions that are directly affected by the draft, since those […]

Ingénierie: les langages formels ont-ils un avenir à l’époque du numérique ?
Après un rappel sur les langages formels d’ingénerie, il s’agit de discuter de la question de leur peu d’usage à l’époque du développement masif du numérique.

Un environnement pour augmenter la collaboration et booster la motivation intrinsèque
Abstract L’apprentissage au 21ème siècle porte de multiples visages et le collaboratif revêt une importance particulière. De plus en plus centré sur l’apprenant et visant à le rendre actif dans son apprentissage, les pratiques éducatives ont évolué et les environnements avec. Dans cette optique de pédagogie active, les élèves travaillent de manière autonome, apportent un […]

To train engineering students to make decision taking in account ethical dimensions
The need to design ethics competencies is presented through the societal context and the InnovENT-E project. The framework of a competency « To manage an ethical issue » is proposed. A statement is presented about the implementation into curricula.

Multi-agent planning and execution with risk analysis and multi-criteria optimization: the case of rescue plans to environmental and humanitarian crisis
A disaster seriously disrupts the functioning of a society and generates human, material and economic losses. Unfortunately, some are weakly predictable such as the terrorist. But even the predictable ones, like the cyclones whose intensity remains difficult to assess are not always easy to forecast in terms of damage. Over the past 10 years, disasters […]
