Some lessons from a 3-year experiment of Problem-based learning in Physics in a French School of engineering
In this experiment, a Problem-based learning methodology (PBL) is used to teach the physics program to engineering students. The efficiency of PBL is measured and compared to traditional teaching methods. Our experiment shows no major differences in terms of knowledge acquisition, conceptualization and physical reasoning. On the other hand, PBL shows an influence on cross-knowledge […]

Maturité des PME en termes de PLM
Ce travail est réalisé dans le contexte du projet INTERREG BENEFITS, qui vise à garder les compétences locales en termes de technologies de l’information et de la communication (TIC), plus précisément les technologies PLM. Le choix du PLM est dû à sa capacité de permettre à l’entreprise étendue (incluant les clients et les fournisseurs) d’échanger […]

Flexible Job Shop Models for solving layout problems Using Coloured petri nets, SML/NJ and Heuristics
In this paper we propose models for solving both the layout manufacturing problems and the scheduling manufacturing systems. These models are based on Coloured petri Nets. The particularity of our models is the possibility to include complex programmable functions inside the petri nets models. In our case the programming language is SML/NJ. The advantage of […]

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 […]
