jumeau numérique
L'évolution des applications de modélisation, de l'aérospatiale à divers autres domaines, souligne l'importance d'une représentation ontologique adaptée et d'une précision de modélisation dans la conception et l'innovation des produits.

Un jumeau numérique est une représentation virtuelle synchronisée en continu d'un actif, d'un processus ou d'un système physique, maintenue grâce à des flux de données bidirectionnels entre des capteurs du monde réel et un modèle informatique dont la fidélité varie de simples tableaux de bord de télémétrie à des simulations physiques complètes résolvant la dynamique des fluides, la mécanique structurelle ou le comportement électrochimique aux échelles de temps opérationnelles.

The construct originated in aerospace and manufacturing — NASA’s vehicle mirroring practice and Siemens’ product lifecycle management infrastructure are canonical early instances — before propagating into energy grid management, urban planning, healthcare facility operations, and supply chain orchestration, each domain imposing distinct requirements on ontological representation, update latency, and model granularity.

Les publications et les brevets indexés ci-dessous traitent de cette architecture complète : protocoles d’intégration et de synchronisation des capteurs, approches de modélisation hybride physique/apprentissage automatique, validation des jumeaux et quantification de l’incertitude, cadres d’interopérabilité et cas de déploiement spécifiques au domaine dans les systèmes industriels, d’infrastructure et biologiques.

integrating MT-InSAR with physics-based and data-driven models for scalable structural health monitoring

Published on 2026-09-02 by @OXFORD

Abstract: AbstractMulti-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) has matured into a credible, non-contact technique for monitoring bridge deformation from individual structures to regional portfolios. The main challenge for routine engineering use is no longer measuring millimetre-scale line-of-sight (LOS) displacement, but interpreting those measurements into defensible statements about structural condition. This review addresses that interpretation problem by synthesising the physica[...]


Our summary: This review synthesizes the fundamentals of MT-InSAR for bridge deformation monitoring and addresses the interpretation of measurements for structural condition assessment. It proposes a hybrid framework combining physics-based and data-driven methods to enhance the scalability and interpretability of monitoring efforts.
