Coverage Maximization in WSN Deployment Using Particle Swarm Optimization with Voronoi Diagram
Coverage area maximization is a crucial issue that must be considered in Wireless sensor network (WSN) deployment as long as it impacts the sensor network efficiency. In this paper, a novel approach based on particle swarm optimization (PSO) and voronoi diagram is developed to solve WSN deployment problem. The objective of the proposed solution is […]

Financial literacy and individual success: Lebanese framework modeling
This paper sheds light on the role the financial literacy features may play amid other determinant factors of individual success. A survey is conducted on a random sample of households’ members, based on the individual perception as an assessment criteria of financial literacy status and career success. A non-parametric method, ctree, and a semi-parametric method, […]

Guaranteeing Information Integrity through Blockchains for Smart Cities
Given the threats that the smart city faces especially tampering the integrity of information, it has become necessary to integrate more robust and decentralized technologies that ensure transparency and sustainability of the system. Blockchain is a technology initially directed to limit the manipulation in financial transactions. One of the most popular currencies adopting this technology […]

COVID-DETECT: A Deep Learning Based Approach to Accelerate COVID-19 Detection
After two years of COVID-19 first infection and its speedy propagation, death and infection cases are till exponentially increasing. Unfortunately, during this a non-fully controlled situation, we noticed that the existing solutions for COVID-19 detection based on chest X-ray were not reliable enough in relation to the number of infected patients and the severity of […]

Towards the Design of a Quick and Universal Questionnaire to Assess the Intuitiveness of Products
The goal of this research is to design a tool to assess intuitiveness of products. Existing scales such as INTUI (Diefenbach and Ullrich 2010, 2015) show some limitations when used by children and/or for evaluating non-digital products. We aim to obtain a more universal questionnaire tool. INTUI questionnaire measures the components of an intuitive interaction […]

Conception de situations instrumentées : étude de cas d’une situation d’apprentissage des concepts du Lean Manufacturing
Comment les concepteurs de situations d’apprentissage instrumentées, aux problématiques pédagogiques régies par les objectifs d’apprentissage, et les chercheurs et développeurs en informatique, aux problématiques scientifiques et techniques, peuvent-ils co-construire les étapes menant de la situation de travail à sa transposition informatique ? Cette communication relate une expérimentation autour d’une situation d’apprentissage des concepts du Lean […]

Une double ontologie pour un méta-cadre théorique
Les recherches sur les situations d’apprentissage instrumentées s’appuient sur des cadres théoriques divers, issues de disciplines différentes. Malgré cela, plusieurs reposent sur une vision commune de l’action humaine comme déterminée à la fois par des facteurs propres à la personne et par des facteurs issus du contexte dans lequel elle se déroule. Cette contribution propose […]

Avatars
Avatars are virtual characters that now belong to the popular culture around video games, social networks, and digital applications in general. However, using an avatar may not be as insignificant as it seems, because avatars, by providing us with a fresh new appearance, may impact the very perception of our own identity. The aim of […]

Visual and Chemical Servoing of a Hexapod Robot in a Confined Environment using Jacobian Estimator
Industrial inspection can be achieved through robotic systems, allowing visual and chemical servoing. A popular scheme for visual servo-controlled robotic is the image-based servoing systems. In this paper, an approach of visual and chemical servoing of a hexapod robot using a visual and chemical Jacobian matrix are proposed. The basic idea behind the visual Jacobian […]

Toward BIM and LPS data integration for Lean site project management: A State-of-the-Art review and recommendations
Over recent years, the independent adoption of Lean Construction and Building Information Modeling (BIM) have shown improvements in construction industry efficiency. Because those approaches have overlapping concepts, it’s thought that their synergic adoption can bring much more benefits. Today, the implementation of the Lean-BIM interactions theoretical framework is still challenging many companies. This paper conducts […]

tout problème de compétence ne relève pas d’un problème de formation
En effet, il m’arrive même, régulièrement, de dire que l’on évalue les individus alors qu’il faudrait également évaluer les organisations. Pour le comprendre, il faut revenir à la notion même de compétence et prendre en compte le fait qu’elle puisse être état, produit et processus ; bagage, résultat ou chemin. Lorsque l’on évalue les compétences […]
