Nous définissons un modèle d’exécution réactif et interactif pour la programmation logique avec contraintes (PLC). Ce modèle d’exécution s’appuie d’une part sur un système de transformation des dérivations CSLD pour l’ajout et le retrait de contraintes et d’atomes dans la requête, et d’autre part sur un résolveur de contraintes dynamiques supportant l’ajout et le retrait incrémental de contrain...

Two-way communication is a key feature in a smart grid. It is enabled by either powerline communication (PLC) or wireless communication technologies. Utilizing both technologies can potentially enhance communication reliability, and many diversity combining schemes have been proposed. However, their assumptions may break under realistic conditions. In this paper, we propose a flexible real-time...

This paper derives a model of high-voltage overhead power line under fault conditions at low radio frequencies. The derived model is essential for design of communication systems to reliably transfer information over high voltage power lines. In addition, the model can also benefit advanced systems for power-line fault detection and classification exploiting the phenomenon of changed conditions...

This paper analyses two schemes of single-stage diode-switched active filters used in new switching power supplies designs to improve the power factor. From the point of view of the power flow, the distortion reduction is based on the improvement of the power conversion processes. Most of the ca/cc switching power supplies consists of two separated parts: a rectifier – in most cases a diode bri...

Using the worldwide already existing power lines as a communication medium for local area networking (LAN) has received much interest for many indoor information sharing applications. However, the indoor power line communication (PLC) channels demonstrate hostile characteristics for broadband signal transmission. A lot of efforts have been made in order to apply some advanced technologies, whic...
