Multi-agent modeling and simulation of wind turbine behavior with failure propagation consideration
Simulation is an interesting technique to represent and predict the behavior of complex system such as wind turbines. In order to get accurate representation of the real turbines, the main factors influencing the operating state of the system must be considered during the development of the model. Stochastic dependencies between components are among the factors […]

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 […]

A model-free reinforcement learning approach for the energetic control of a building with non-stationary user behaviour
We consider a system providing a service to a user (smart building, vehicle…) and allowing the user to interact with it. The service provided to the user regulates physical signals of the user’s surroundings (lighting, heating, radio sound,…). The user can interfere with the system to affect the values of those signals to adjust the […]

Multi-component modeling and classification for failure propagation of an offshore wind turbine
Purpose Improving reliability is a key factor in reducing the cost of wind energy, which is strongly influenced by the cost of maintenance operations. In this context, this paper aims to propose a degradation model that describes the phenomenon of fault propagation to apply proactive maintenance that will act on the cause of failure to […]

InHARD – Industrial Human Action Recognition Dataset in the Context of Industrial Collaborative Robotics
Nowadays, humans and robots are working more closely together. This increases business productivity and product quality, leading to efficiency and growth. However, human and robot collaboration is rather static; robots move to a specific position then humans perform their tasks while being assisted by the robots. In order to get a dynamic collaboration, robots need […]

Modeling Attack-Defense Trees’ Countermeasures using Continuous Time Markov Chains
ADTrees (Attack-Defense Trees) are graphical security mod- eling tools used to logically represent attack scenarios along with their corresponding countermeasures in a user-friendly way. Many researchers nowadays use ADTrees to represent attack scenarios and perform quan- titative as well as qualitative security assessment. Among all di erent existing quantitative security assessment techniques, CTMCs (Continu- ous […]

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 […]

A New Dataset of People Flow in an Industrial Site with UWB and Motion Capture Systems
Improving performance and safety conditions in industrial sites remains a key objective for most companies. Currently, the main goal is to be able to dynamically locate both people and goods on the site. Security and access regulation to restricted areas are often ensured by doors or badge barriers and those have several issues when faced […]

MODULAR AND TRANSPORTABLE MANUFACTURING UNIT PROVIDING A HIGH LEVEL OF INDUSTRIAL SECURITY, PARTICULARLY FOR ADDITIVE METAL MANUFACTURING
The unit (1) comprises a plurality of modules (M1 to M4) which are constructed from transport containers. The modules are assembled in a removable manner and have, between two juxtaposed modules, at least one spatial communication zone which comprises opposite openings and joining and sealing means. The unit comprises a confined zone (ZC) which accommodates […]

Mixed-integer linear programming models for the simultaneous unloading and loading processes in a maritime port
This paper discusses the jointly quay crane and yard truck scheduling problems (QCYTSP) with unloading and loading containers from/to vessel(s) in the same time. Yard trucks transport the containers to/from yard locations with all containers that are homogeneous.We propose a mixed integer linear programming model to solve the scheduling problem. We consider in this study, […]

Dual Color-Image Discriminators Adversarial Networks for Generating Artificial-SAR Colorized Images from SENTINEL-1 Images
In this paper, we introduce a new generative adversarial network (GAN) with dual image-color discriminators, to predict Artificial-SAR colorized images from SAR ones (Sentinel-1). Based on the conventional architecture of GANs, we employ an additional color discriminator that evaluates the differences in brightness, contrast, and major colors between images, while the image discriminator compares texture […]

Dynamic scheduling of robotic mildew treatment by UV-c in horticulture
Thanks to new technologies, it is possible to make an automatic robotic treatment of plants for the mildew in greenhouses. The optimization of the scheduling of this robotic treatment presents a real challenge due to the continues evolution of disease level. The conventional optimization methods can not provide an accurate scheduling able to eliminate the […]
