Optimisation de transducteurs ultrasonores hautes fréquences à base de ZnO pour applications MEMS, Optimization of high-frequency ZnO-based ultrasonic transducers for MEMS applications

Reda Aitayad

Ce manuscrit porte sur la fabrication et l’optimisation de transducteurs à ondes acoustiques de volume (BAW) à base de couches minces de ZnO. L’optimisation concerne d’abord le matériau piézoélectrique en couche mince : le dépôt du ZnO par pulvérisation cathodique RF est optimisé, et la condition…, This manuscript focuses on the fabrication and optimization of bulk acoustic wave (BAW) transducers based on ZnO thin films. The optimization first concerns the piezoelectric thin-film material: ZnO deposition by RF magnetron sputtering is optimized, and the 80% Ar / 20% O₂ condition makes it…

Deep learning for motor-current-based predictive maintenance of industrial robots: from unsupervised anomaly detection to progressive fault diagnosis, Apprentissage profond pour la maintenance prédictive des robots industriels basée sur le courant moteur : de la détection non supervisée d'anomalies au diagnostic progressif de défauts

Douimia Soufiane

Predictive maintenance of industrial robots is a strategic concern of automotive manufacturing, where takt-time production lines and brownfield infrastructure make every unplanned stoppage costly. This thesis, conducted in partnership with Toyota Motor Manufacturing France (TMMF), takes as case…, La maintenance prédictive des robots industriels est un enjeu stratégique de l'industrie automobile, où les lignes en flux tendu et les infrastructures brownfield rendent tout arrêt non planifié coûteux. Cette thèse, conduite en partenariat avec Toyota Motor Manufacturing France (TMMF), prend…
