This paper presents the BuildSysPro Modelica library developed by the department of Energy in Buildings and Territories (EnerBaT) of EDF R&D. After a description of the library’s structure and content, BESTEST validation results and a use case are presented. This library is designed to be used in several contexts including building physics research, global performance evaluation, technology dev...

The European Journal of Dermatology and the European Dermatology Forum have agreed to reproduce, with permission, the White Book© 2005 ABW Wissenschaftsverlag GmbH. This work was a joint enterprise bringing together many European dermatologists, chosen to obtain a broad representation from across Europe and according to their expertise. Although the content of the “White Book” was primarily int...

Ce rapport de recherche résume l'avancement de travaux menés conjointement par l'IRCCyN et l'Ecole Polytechnique de Montréal concernant la résolution du problème inverse pour l'imagerie sismique des fondations de pylônes électriques. Nous abordons plusieurs méthodes de type « carto-graphie ». Nous nous intéressons plus particulièrement à des méthodes basées sur une formulation bilinéaire du pro...

This paper presents a system level approach for the synthesis of hard real-time multitask application specific systems. The algorithm takes into account task precedence constraints among multiple hard real-time tasks and targets a multiprocessor system consisting of a set of heterogeneous off-the-shelf processors. The optimization goal is to select a minimal cost multi-subset of processors whil...

Earlier studies have observed that in moderately-loaded real-time database systems, using an Earliest Deadline policy to schedule tasks results in the fewest missed deadlines. When the real-time system is overloaded, however, an Earliest Deadline schedule performs worse than most other policies. This is due to Earliest Deadline giving the highest priority to transactions that are close to missi...

In this paper, the problem of finding a near-optimal routing solution for a set of real time applications with multicast traffic flows in a meshed core network is studied. Such kind of network is typically a core network of automobile, airplane, or industry control networks. We will introduce our routing planning methodology based on a genetic algorithm, and will focus on the model with Earlies...

We analyze the Earliest-Deadline-First (EDF) scheduling discipline within the framework of statistical multiplexing. We derive techniques for bounding the probability of delay violations when the session injections are independent. This enables us to determine whether a given set of sessions can all meet their delay bounds with the required violation probability. These techniques can be used by...

While the quality of service (QoS) profiles for a number of general packet radio service (GPRS) classes has been specified [1] by ETSI, how QoS management is provided by means of traffic scheduling, traffic shaping, and connection admission control, in a GPRS network is an implementation issue that is attracting significant current research interest. This paper presents an evaluation of several...

1 Hierarchical schedulers are getting increased attention in many research projects because they bring in flexibility, they can take advantage of the best features of different scheduling policies, and allow the composability of applications developed under different scheduling strategies. Most commercial real-time operating systems have an underlying fixed priority scheduler, and for this reas...
