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 […]

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 […]

Text input tools’ complementarity in immersive virtual environments
This study presents a user test in order to ascertain the advantages and disadvantages of three different text input methods in immersive virtual environment: individual Speech-to-Text, collective Speech-to-Text and a virtual keyboard named Drum-Like Keyboard. We measured participants’ user experience, especially related to usability and utility, in order to offer relevant recommendations to people seeking […]

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 […]

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 […]

L’éthique, une compétence à laquelle former les ingénieurs
Dans leurs activités, les ingénieurs sont conduits à traiter des dilemmes éthiques. Des codes de conduite peuvent les aider à cette fin, mais ils peuvent être insuffisants face à la nouveauté des situations. Pour les former les ingénieurs à faire face à de telles situations, notre approche a été de considérer l’éthique comme une compétence. […]

Safety analysis of train control system based on model-driven design methodology
Embedded system design is a complex process that demands an extensive system level modeling. Its implementation encompasses software and hardware components and its interconnections. In such systems, it is widely recognized that safety should be considered at the design stage itself, particularly at the architectural level to minimize the design effort. This paper presents a […]

Mathematical model for dynamic suppliers’ selection strategy in multi-period supply planning with lead-times uncertainty
In the supply planning, the management of uncertainties is the most difficult task but becomes increasingly important in the constantly changing business environment. In literature, most paper examine the uncertainty demand under the assumption of the constant order lead-times. However, lead-time is rarely constant in real time because of unpredictable events in the supply system […]

THE SHORT AND LONG RUN CAUSALITY RELATIONSHIP BETWEEN PUBLIC HEALTH SPENDING AND ECONOMIC GROWTH: EVIDENCE FROM TUNISIA AND MOROCCO
This study aims to analyze the short run and long run relationship link between economic growth and public health spending in Tunisia and Morocco cover the 1980-2017 periods. The basic analysis process involves four steps: stationarity test, Bound tests for Cointegration, ARDL approach inspired by Pesaran et al. (2001), and VECM method. The results confirm […]
