SR-Code: Smart Relay Network Coding for Data Collection for Wireless Sensor Networks
Reliability in data collection for wireless sensor networks is one of the major problems in IoT applications. Sensor nodes are usually placed in harsh conditions where data communication is at risk of losing packets. Retransmissions are considered costly in terms of delay and power consumptions, especially that wireless sensor nodes are battery operated. In this […]

An Agile Development For Platoon System Based on Verification and Validation
This paper introduces a verification and validation (V&V) process in a product life-cycle, where we consider a V&V process as the composition of the three tasks: formal verification, simulation and experimentation. The considered application is a platoon system, a set of autonomous vehicles that move together without any material connection. The platoon system development considers […]

Efficient parameterization for Automatic speaker recognition using Support Vector Machines
Recent advances in the field of speaker recognition have proved to highly outperform algorithms. However this performance degrades when limited data are presented. This paper presents examples on how SVM can improve speaker recognition. The main contribution in this approach is the use of new low-dimensional vectors when training data are limited. We show how […]

An Improved Approach for Text-Independent Speaker Recognition
This paper presents new Speaker Identification and Speaker Verification systems based on the use of new feature vectors extracted from the speech signal. The proposed structure combine between the most successful Mel Frequency Cepstral Coefficients and new features which are the Short Time Zero Crossing Rate of the signal. A comparison between speaker recognition systems […]

Project-based learning and professional identity construction
CESI, a French school of engineering, has implemented a project-based learning curriculum in its combined work and study engineering degree programme, in October 2015. The new school curriculum is based on multidisciplinary 2 to 5 week projects, carried out in small groups and using loops inspired by the Deming Wheel as a problem solving methodology. […]

Study of the behavior of solid particle in a lid-driven cavity flow
This study predicts the fluid flow and solid particle dynamics within a three dimensional lid-driven cavity with the Eulerian-Lagrangian (E-L) approach. The first step was to solve the fluid phase without any solid particle inside the domain. The Reynolds number up to 1,000 was defined and that implies a laminar flow inside the cavity. A […]

Collaboration management framework for OEM – suppliers relationships: a trust-based conceptual approach
Due to the increased competitiveness and the diversity of requirements in today’s markets, manufacturing companies need to join their competencies and resources to propose innovative solutions for each specific market, with the possibility to transpose these solutions to another market, by means of slight adaptations. Thus, manufacturing firms must constantly conduct new collaborations with known […]

On The Privacy-Utility Tradeoff in Participatory Sensing Systems
The ubiquity of sensors-equipped mobile devices has enabled citizens to contribute data via participatory sensing systems. This emergent paradigm comes with various applications to improve users’ quality of life. However, the data collection process may compromise the participants’ privacy when reporting data tagged or correlated with their sensitive information. Therefore, anonymization and location cloaking techniques […]

Pédagogie par projets et construction de l’identité professionnelle
L’école d’ingénieurs du CESI met en place l’Apprentissage Actif Par Projets (A2P2) dans sa formation d’ingénieurs depuis octobre 2015. L’apprentissage y est articulé autour de projets à réaliser en groupes, selon des boucles de résolution de problème. Des travaux de recherche sur la formation antérieure à l’A2P2 ont étudié le rôle de moments clés dans […]

Recommandations pour la conception de plans d’orientation accessibles aux déficients visuels
Dans le cadre de l’application de la loi du 11 février 2005, tous les Etablissements Recevant du Public (ERP) doivent offrir un accès à l’information à tout visiteur y compris aux personnes atteintes de déficience visuelle. Cependant il n’existe pas de règles de conception normalisées pour les plans d’orientation. Dans cet article, nous présenterons une […]
