Photocatalytic degradation and photo-generated hydrophilicity of Methylene Blue over ZnO/ZnCr2O4 nanocomposite under stimulated UV light irradiation
This paper deals with the relationship between photocatalysis and photo-generated hydrophilicity under UV light irradiation of ZnO/ZnCr2O4 nanocomposite film prepared via spray pyrolysis method. XRD investigations indicate that the nanocomposite sample show the presence of würtzite ZnO phase having crystallites oriented preferentially along c-axis with the presence of a secondary phase spinel of ZnCr2O4. Indeed, […]

Bi-Objective Indirect Optimization of Robotic Transportation Task Assignment Based on Auction Mechanism
Flexible manufacturing systems (FMS) are used to ensure the production of several products using the same set of production tools. Transportation tasks using robots are introduced in order to increase the routing flexibility of the FMS. Several researchers are interested in the optimization of the production planning but few of them considered the transportation planning. […]

A Simulated Multi-Objective Model for Flexible Job Shop Transportation Scheduling
This paper proposes a new dynamic algorithm based on simulation approach and multi-objective optimization to solve the FJSP with transportation assignment. The objectives considered in scheduling jobs and transportation tasks in a flexible job shop manufacturing system include makespan, robot travel distance, time difference with due date and critical waiting time. The results obtained from […]

Automatic generation of building information models from digitized plans
This paper proposes a new approach to creating Building Information (BIM) models of existing buildings from digitized images. This automatic approach is based on three main steps. The first involves extracting the useful information automatically from rasterized plans by using image processing techniques that include segmentation, filtering, dilation, erosion, and contour detection. This information feeds […]

On the use of particle-wall interaction models to predict particleladen flow in 90-deg bends
The objective of this work is to evaluate the capability of different combinations of a turbulence model and a Lagrangian particle tracking (LPT) model integrating a particle-wall interaction (PWI) model to predict particle-laden flow in 90-deg bends, as well as the impact of the PWI model on the prediction of the referred flow. The experimental […]

Ordonnancement dynamique des tâches robotisées pour le traitement du mildiou par radiation UV-c dans l’horticulture
Dans cet article nous présentons une méthode d’ordonnancement dynamique appliquée au traitement robotisé de la maladie du mildiou dans les serres. Le traitement se fait par radiation ultraviolet (UV-c) avec un robot mobile autonome muni de lampes UV-c. Dans un premier temps, nous avons développé l’environnement du robot dans la serre dans un simulateur basé […]

Managing uncertainty during CBR systems vocabulary maintenance using Relational Evidential C-Means
Due to the incremental learning of Case-Based Reasoning (CBR) systems, there is a colossal need to maintain their knowledge containers which are (1) the case base, (2) similarity measures, (3) adaptation, and (4) vocabulary knowledge. Actually, the vocabulary presents the basis of all the other knowledge containers since it is used for their description. Besides, […]

A Novel Strategy for Energy optimal designs of IoT and WSNs
Many IoT applications demand devices operating on battery, which restricts the useful life of the developed solution as most scenarios do not allow replacement of batteries. Given a target period of survivability of IoT devices, we must design devices and sub-systems meeting the estimated energy con-sumption rate so as meet target lifetime. Thus, for a […]
