Une approche basée sur l’agrégation des scénarios pour résoudre un problème de planification de désassemblage sous incertitude des délais de remise à neuf
De nos jours, la recherche sur les procédés de désassemblage suscite un intérêt croissant. L’objectif principal est d’obtenir des composants de valeur et de séparer ceux qui peuvent affecter l’environnement [1]. Cependant, le processus de désassemblage est devenu très vulnérable et loin d’être déterministe. En effet, il implique un degré élevé de variabilité associé au […]

Building Thermal-Network Models: A Comparative Analysis, Recommendations, and Perspectives
The development of smart buildings, as well as the great need for energy demand reduction, has renewed interest in building energy demand prediction. Intelligent controllers are a solution for optimizing building energy consumption while maintaining indoor comfort. The controller efficiency on the other hand, is mainly determined by the prediction of thermal behavior from building […]

SPD Siamese Neural Network for skeleton-based hand gesture recognition
This article proposes a new learning method for hand gesture recognition from 3D hand skeleton sequences. We introduce a new deep learning method based on a Siamese network of Symmetric Positive Definite (SPD) matrices. We also propose to use the Contrastive Loss to improve the discriminative power of the network. Experimental results are conducted on […]

Fog-supported Low Latency Monitoring of System Disruptions in Industry 4.0: A Federated Learning Approach
In recent years, industrial alarm systems have undergone a considerable development, in terms of accuracy, complexity of their presentation and their management, and system reliability. However, alarm management systems suffer generally from the presence of poorly configured alerts, as well as numerous nuisance alarms (i.e., noise) or even alarm flooding events. This requires an immediate […]

BIM Data Flow Architecture with AR/VR Technologies: Associated Use Cases in Architecture, Engineering and Construction
The construction of a building comprises several phases and involves many stakeholders. As projects have become more and more complex, the Building Information Modeling (BIM) methodology was proposed to unify projects around a Digital Twin of the information necessary for collaboration. In recent years, Augmented Reality (AR) and Virtual Reality (VR) have shown their relevance […]

Survey on Cooperative Perception in an Automotive Context
The idea of cooperation has been introduced to self- driving cars about a decade ago with the aim to reduce the occlusion caused by other users or the scene. More recently, the research efforts turned toward cooperative infrastructure bringing a new kind of the point of view as well as more processing power. This paper […]
