Multi-agent based simulation-optimization of maintenance routing in offshore wind farms
Offshore wind energy is expected to be the first source of energy in the future thanks to its numerous advantages. However, its maintenance is a complex and costly activity, which is increasingly attracting the attention of researchers and industrials. This paper proposes a simulation-optimization approach for the routing and the scheduling of maintenance for offshore […]

Towards the Design of a Quick and Universal Questionnaire to Assess the Intuitiveness of Products
The goal of this research is to design a tool to assess intuitiveness of products. Existing scales such as INTUI (Diefenbach and Ullrich 2010, 2015) show some limitations when used by children and/or for evaluating non-digital products. We aim to obtain a more universal questionnaire tool. INTUI questionnaire measures the components of an intuitive interaction […]

tout problème de compétence ne relève pas d’un problème de formation
En effet, il m’arrive même, régulièrement, de dire que l’on évalue les individus alors qu’il faudrait également évaluer les organisations. Pour le comprendre, il faut revenir à la notion même de compétence et prendre en compte le fait qu’elle puisse être état, produit et processus ; bagage, résultat ou chemin. Lorsque l’on évalue les compétences […]

Expérience et conduite d’entretiens d’accompagnement au sein d’une formation d’ingénieur par apprentissage
Cette étude contribue à la connaissance du rôle de l’expérience dans la conduite d’entretiens d’accompagnement menés avec des apprentis-ingénieurs. Elle montre le travail de l’expérience avec les accompagnés sous la forme d’une aide à la maîtrise de situations dynamiques. Ce travail impacte l’expérience des accompagnés. Il mobilise aussi, et construit, l’expérience des accompagnateurs. Leurs expériences […]

Integrated quay crane and yard truck scheduling problem at port of Tripoli-Lebanon
The scheduling problem is one of the most important operation in maritime ports. In this study we solved the scheduling problem for a single quay crane and multiple yard trucks in port of Tripoli-Lebanon. In a previous study we proposed two exact methods for this problem but we faced a problem for large instances in […]

X-ray photoabsorption-induced processes within protonated rifamycin sodium salts in the gas phase
Up to now, the response of antibiotics upon ionizing radiation has been very scarcely reported. Here, we present the results of X-ray photoabsorption experiments on isolated rifamycin, a broad-range antibiotic against Gram-positive and Gram-negative bacteria. A mass spectrometer has been coupled to a synchrotron beamline to analyze cationic products of photoabsorption on protonated rifamycin dimer […]

La didactique professionnelle pour relier travail et formation
Alors qu’aujourd’hui les situations de travail deviennent des objets pour la formation, la didactique professionnelle se présente comme un cadre théorique et une approche méthodologique qui assurent une performance aux activités de transmission et développement de compétences. Quatre articles majeurs sur le lien Travail et Formation y sont présentés, ils couvrent une large période de […]

use case study comparing augmented reality (AR) and electronic document-basedmaintenance instructions considering tasks complexity and operator competency level
Augmented reality (AR) is more and more used in the industrial context for maintenance, assembly operation. However, owing to the evolution and maturity of the technology, it is still necessary to evaluate the usage and benefits of AR in an industrial context to go further than proof of concept. As such, this paper proposes an […]

Adherence of geopolymer and pultruded composite substrates: influence of adhesive type and surface treatment
In the last years, the use of adhesive bonding is increasing as an alternative to traditional joining techniques due to their advantages such as ease of application, low weight and the good mechanical properties. To ensure good adherence between the substrates, adequate materials and surface treatment are required. The main objective of this work is […]

Fiber-matrix bond strength by pull-out tests on slag-based geopolymer with embedded glass and carbon fibers
The reinforcement efficiency on a composite depends on the effective transfer of the stress between matrix and fiber. This work presents an experimental and comparative study of fibermatrix bond strength for fiber-matrix interface between glass fibers and carbon fibers added to the slag-based geopolymer matrix. This analysis was performed by pull-out test. A total of […]

Effect of Scalping on the Mechanical Behavior of Coarse Soils
This paper aims at presenting a study of the effect of scalping methods on the mechanical properties of coarse soils by resorting to numerical simulations based on the discrete element method (DEM) and experimental triaxial tests. Two reconstitution methods are used, designated as scalping method and substitution method. Triaxial compression tests are first simulated on […]

Reliability-driven Automotive Software Deployment based on a Parametrizable Probabilistic Model Checking
several interacting nodes. Designing such systems includes hardware parts and software parts. The software part acquires in importance since it handles the resources and services to interact with the hardware part. The paper introduces a novel deployment-decision making based on PRISM probabilistic model checker that takes software components and the physical platform to produce a […]
