Impact of Radio Propagation in Buildings on WSN’s Lifetime
Nowadays, Wireless Sensor Networks (WSN) are a commonly used technology in Smart Buildings applications. Generally, WSN suffer from finite energy resources (limited lifetime), and limited network coverage (due to transmission range). The most consistent works on energy consumption and radio transmission modeling for WSN, are not taking into account realistic constraints. However, radio propagation is […]

WSN’s Modeling For a Smart Building Application
Recently, wireless sensor networks are more and more used in smart building applications, due to their capability to collect data on all phenomena that happens in the building. The most important problem related to this kind of networks, is the limited lifetime of nodes, caused by their finite embedded source of energy (batteries). In order […]

On enhancing network-lifetime in opportunistic Wireless Sensor Networks
Network lifetime has become the key characteristic for evaluating sensor networks in an application-specific way. In this paper, we focus on Mobile Wireless Sensor Networks, which are specific opportunistic networks because of their poor connectivity among the mobile sensors, and thus it is difficult to form a well connected mesh network for transmitting data through […]

Quality control planning to prevent excessive scrap production
This paper presents a risk-based approach for quality control planning of complex discrete manufacturing processes, to prevent massive scraps to occur. An analytical model is developed to optimize the quality control plan (QCP) subject to inspection capacity limitation and risk exposure objectives. The problem is then formulated as a constrained capacity allocation problem. A dedicated […]

A Business Process Modelling Approach to Improve OEM and Supplier Collaboration
Nowadays, Small and Medium sized Enterprises (SMEs) are facing fast changes in technological advancement. These changes encourage them to be more innovative and to offer their Original Equipment Manufacturers (OEMs) quality products with ever shorter deadlines, which is not an easy task. This project (BENEFITS) aims to provide innovative solutions to keep the most exploitable […]

Application of Cross Wavelet Transform for ECG Pattern Analysis and Classification
In this paper, we use cross wavelet transform (XWT) for the analysis and classification of electrocardiogram (ECG) signals. The cross-correlation between two time-domain signals gives a measure of similarity between two waveforms. The application of the continuous wavelet transform to two time series and the cross examination of the two decompositions reveal localized similarities in […]

Entrepreneur’s professional identity profile
The notion of professional identity is applied here in order to define the profile of a new entrepreneur. The construction of this profile has first of all been done from a bibliography. It gives many benchmarks of what a training cursus should focus on.

Mise en œuvre de l’approche par problèmes dans une école d’ingénieurs: effets cognitifs et conatifs
Cette communication présente quelques effets cognitifs et conatifs qui ont été provoqués par la mise en oeuvre de l’Apprentissage par problèmes (APP) en physique dans une école d’ingénieurs. Après avoir présenté les différences et les ressemblances entre la démarche APP et celle des situations-problèmes, la communication précise les raisons de l’introduction de cette pédagogie et […]

Mutual Learning: A Systemic Increase in Learning Efficiency to Prepare for the Challengesof the 21st Century
One of the few certainties we have about our collective future is that it will require a massive amount of learning, by just about everybody, everywhere. The time for generating as many creative and collaborative knowledge builders has come. Therefore, improving the efficiency of learning could very well become a key leverage point for successfully […]
