Inoovas – Industrial Ontology for Operation in Virtual and Augmented Scene: the architecture
Digitalization of industry brings new usage perspectives of digital tools as Virtual Reality (VR) and Augmented Reality (AR). However there is still open issue for integrating their usage into information system workflow of the industry. Therefore the paper proposes a workflow and an ontology based on the collaborators’ skills to allow the creation of AR […]

La culture d’innovation dans les organisations françaises
D’un point de vue macroéconomique, il y a consensus quant à la nécessité d’innover. En France, les organisations concentrent leurs efforts d’innovation essentiellement sur la R&D, alors que d’autres stratégies sont plus efficaces. Cette situation peut être liée à la nature des indicateurs et des incitations à l’innovation, centrés sur les investissements réalisés plutôt que […]

Social identity cues to improve creativity and identification in face-to-face and virtual groups
This research draws on the social identity approach to investigate group performance in face-to-face and virtual brainstorming settings. In particular, we display Social Identity Cues (SIC) on participants or on avatars to foster group membership. We compare four conditions in a factorial design: Brainstorming in Face-to-face or Virtual setting, With or Without SIC. Seventy-two students […]

Multi-Objective WSN Deployment Using Genetic Algorithms Under Cost, Coverage, and Connectivity Constraints
A wireless sensor network (WSN) deployment requires the identification of optimal network nodes (sensor and sink) positions in an area of interest, to ensure the best network performances (Senouci et al. in Smart Communications in Network Technologies (SaCoNeT), 2014 International Conference on, IEEE, pp 1–6, 43). The deployment process can be divided in two main […]

Engineering students’ use of creativity and development tools in conceptual product design: What, when and how?
As creativity has become a requisite skill for engineers and a part of their basic training, one of the challenges in engineering education is to supply students with a good understanding of creativity and development tools. The aim of this study was to assess the effectiveness of these tools during a conceptual product design challenge. […]

Persona Logical Thinking: Improving requirements elicitation for multidisciplinary teams.
To be more successful, innovation projects need a multidisciplinary team to cross and challenge several knowledge elds and viewpoints. However, de ning methods to be used by multidisciplinary design teams is not straightforward since a single method has to match di erent skills and personality types. Our main objective is to provide a new method […]

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 […]
