A Unified Statistical Framework for Multicopter Propeller Damage Diagnosis Based on Functionally Pooled Models and Bayesian Quantification: Experimental Flight Test Assessment
Shinan Huang, Jingxi Zhu, Fotis Kopsaftopoulos
In this work, a stochastic time series-based framework is introduced for multicopter propeller damage diagnosis using functionally pooled autoregressive (FP-AR) models. The framewo…
Data-Driven Structural State Estimation via Multi-Fidelity Gaussian Process Models
Yiming Fan, Fotis Kopsaftopoulos
Guided wave-based techniques have been used extensively in Structural Health Monitoring (SHM). Models using guided waves can provide information from both time and frequency domain…
Guided Wave-Based Structural Awareness Under Varying Operating States via Manifold Representations
Yiming Fan, Dimitris G Giovanis, Fotis Kopsaftopoulos
Guided wave-based structural health monitoring (SHM) remains a powerful strategy for identifying early-stage defects and safeguarding vital aerospace structures. Yet, its practical…
Data-driven Framework for Forward and Inverse Problems in Guided Waves-Based Structural Health Monitoring Under Varying Environmental and Operating Conditions
Yiming Fan, Fotis Kopsaftopoulos
Recently, guided waves-based techniques have garnered increased attention from researchers in the field of Structural Health Monitoring (SHM) for damage detection and quantificatio…
