Abstract

The Aviation Industry has been booming for several decades and is expected to keep growing in the future. Therefore, Air Traffic Management (ATM) tools are likely to be soon overwhelmed by the demand. The Single European Sky ATM Research Program (SESAR) 2020, controlled by EUROCONTROL, intends to revisit the management of aeronautical information along its full lifecycle and across the whole European ATM system. The efficient sharing of information over large scale Cyber Physical Systems (CPSs) is a non-trivial problem that raises several challenges including data lineage, data consistency, access rights management and privacy-preservation. Part of the SESAR initiative, System-Wide Information Management (SWIM) project defines standards to enhance the security of aeronautical data shared among stakeholders. Most of its propositions include centralized or partially centralized mechanisms in order to enforce data confidentiality, and privacy. In this paper, we intend to discuss how blockchains can improve the sharing of sensitive data over the ATM system. More specifically, we use the example of flight data and describe a high-level Blockchain-based concept that mimics the decentralized nature of existing A TM system to provide a reliable, distributed storage platform for flight information.

Abstract

International audience; This paper describes the analysis of recorded data parameters from electrical battery ageing during electric vehicle use. These data allow traditional battery ageing investigation based on resulting capacity fade and resistance raise. The measured variables are examined in order to explain the battery ageing obtained during the experiment. Such study enables us to identify the main ageing factors. Then, detailed statistical dependency explorations present results on battery ageing phenomena. All studies are done on real data collected from Lithium-ion battery; thereby results demonstrate and quantify a relationship between variables and battery ageing mechanisms.
