For centuries, the interaction between the transport and hydrographic networks represents a signifcant issue in a country such as France. For example, the French railway network includes 1700 river-crossing structures and an important length of embankments either forming river banks or adjacent to watercourses exposed to scouring processes. Recentl...
Because stopping a service to apply updates raises issues, Dynamic Software Updating studies the application of updates on programs without disrupting the services they provide. This is achieved using specific mechanisms operating updating tasks such as the modification of the program state. To achieve transparency, Dynamic Software Updating system...
Les Lignes directrices 05/2021 sur l’interaction entre l’application de l’article 3 et les dispositions sur les transferts internationaux prévues au chapitre V du RGPD du Comité européen de protection des données poursuivent l’approche territoriale maximaliste adoptée par l’UE au moins depuis Google Spain (2014) mais elles reflètent surtout la reco...
CTS 2021, 16th IFAC Symposium on Control in Transportation Systems, Lille, FRANCE, 08-/06/2021 - 10/06/2021
The IFAC Symposium on Control in Transportation Systems (CTS'2021) was held in Lille from 8-10 June 2021 in a virtual form. This symposium is the 16th in the series of triennial symposia organized by the IFAC Technical Committee 7.4 on Transportation Systems. These symposia have a long tradition, starting in 1970 in Versailles, France, and continui...
Rapid growth of Internet of Things (IoT) devices dealing with sensitive data has led to the emergence of new access control technologies in order to maintain this data safe from unauthorized use. In particular, a dynamic IoT environment, characterized by a high signaling overhead caused by subscribers' mobility, presents a significant concern to en...
Les Systèmes d'Enclenchement Ferroviaire (SEF) basés sur des relais sont des systèmes critiques, ils doivent être spécifiés et leur sécurité doit être prouvée afin de garantir l'absence de dangers lors de leurs exécutions. Toutefois, il s'agit d'une tâche difficile, car les SEF à relais ne sont généralement modélisés que de manière structurelle, de...
Cybersecurity is a real challenge on many levels for the transportation sector and its sub-sectors (air, maritime, ports, road...). While some aspects remain sub-sector specific, thereby making cy- bersecurity issues difficult to address, this report aims to understand the landscape and come up with a horizontal and holistic understanding of the cy...
We tackle a stochastic version of the Critical Node Problem (CNP) where the goal is to minimize the pairwise connectivity of a graph by attacking a subset of its nodes. In the stochastic setting considered, the outcome of attacks on nodes is uncertain. In our work, we focus on trees and demonstrate that over trees the stochastic CNP actually genera...
The monitoring of railway tracks can be performed through several measurement techniques. Recently, a method of diagnosing the railway track has been proposed using fiber Bragg gratings integrated inside the railway sleeper. An analytical model for the dynamics of railway sleepers has been developed allowing calculation of the sleeper responses. In...
