Analysis of items recommendations methods for heritage sites
When visiting a heritage site for the first time, the visitor can be overtaken by the amount of available contents, such as paintings, artworks, etc. Some heritage sites possess very large collections with various items. Historic sites possess very large collections and their main purpose is to make these available and attractive to the public. […]

Indoor geolocation based on earth magnetic field
—One of the most recent and popular tourism application is the virtual visits (virtual tour guide) which are based on Augmented/Virtual Reality technology (AR/VR). Such systems suffer from the lack of precise indoor geolocation of visitors within the cultural heritage site. This issue can be resolved by using smartphone (and tablets) embedded sensors, which can […]

Modèle de données pour la création d’environnement interactif en réalité virtuelle et augmentée
Un des enjeux de l’industrie du futur passe par l’intégration des nouvelles technologies, telles que la réalité virtuelle (RV) et augmentée (RA), dans ses processus. Toutefois, bien que les avantages de l’utilisation de ces technologies se font sentir, la création tout comme l’édition de contenu reste problématique car souvent lourd en temps humain. En effet, […]

Collaborative design tools in engineering: Insight to choose the appropriate PLM software
The shift from sequential to concurrent engineering has led to changes in the way design projects are managed. In order to assist designers, many effective tools have been developed to support collaborative engineering. Nowadays, industrial scenarios encourage companies to adopt product lifecycle management solutions, even if they may not be able to understand their benefits. […]

Innovation culture in organizations
The components of the innovation culture are presented and summarized in a five-branch model called ETOILe (Environment, Team, Organization, Individuals and Leaders). The objective of this model is to provide a unified vision of the dimensions of innovation culture for the use of enterprises, practitioners, researchers and trainers. It was used as a basis for […]

Evaluating RANS turbulence models to predic the airflow in a duct bend
The main objective of this study is to evaluate the accuracy of some Reynolds Averaged Navier-Stokes (RANS) models to predict the behavior of the turbulent flows in a horizontal circular duct bend. The selection of the RANS models tested follows the capability of each model to describe the flow near the wall. Therefore, five turbulence […]

Integrated Production Planning and Quality Control for Linear Production Systems Under Uncertainties of Cycle Time and Finished Product Quality
This work considers serial production systems with several process steps and a possible quality control at final step. It deals with the problem of optimizing planned lead time when the real lead time for each process is stochastic and the finished product quality is uncertain unless it is inspected. Three analytical models are proposed aiming […]

Optimization of multi-period supply planning under stochastic lead times and a dynamic demand
Supply planning and inventory control are vital in Supply Chain (SC) optimization processes for companies that aim to produce highest-quality finished product at lowest cost and right on time. Optimization means planners’ need to reduce average stock levels and determine the optimal safety lead-times. This study deals with a multi-period production planning problem with a […]

Meta-heuristique hybride pour l’optimisation du déploiement de Réseaux de Capteurs Sans Fil (RCSF)
Durant la dernière décennie, les réseaux de Capteurs Sans-Fil (RCSF) ont attiré l’attention de la plupart des communautés de recherche. Leur taille miniature ainsi que leur coût qui ne cessent de décroitre et leur aspect non destructif les places parmi les techniques les plus adoptés dans de multiples secteurs d’activité : industrie, santé, véhicules autonomes, […]
