Moisture-Induced Bias Drift in a Fiber-Optic Gyroscope

In a recent publication we reported a theoretical analysis and experimental validation of the strain induced by moisture along the fiber of the sensing coil in a fiber-optic gyroscope (FOG). This strain induces a slow nonreciprocal phase shift in…

Integrating Fourier Neural Operators with Diffusion Models to improve Spectral Representation of Synthetic Earthquake Ground Motion Response

Nuclear reactor buildings must be designed to withstand the dynamic load induced by strong ground motion earthquakes. For this reason, their structural behavior must be assessed in multiple realistic ground shaking scenarios (e.g., the Maximum…

Detecting underground water leak from the pipelines by radar and infrared techniques

Water leaks in urban underground pipelines not only cause economic losses but also result in structural damage to roads and buildings. Currently, there are several methods for detecting water leaks, such as pressure/flow sensors or fiber optics, but…

Ultrasonic scattering in polycrystalline materials with elongated grains: A comparative 3D and 2D theoretical and numerical analysis

In this paper, a previously developed theoretical model for the ultrasonic elastic wave scattering, based on the Stanke and Kino model and applicable to both 2D and 3D single-phase untextured polycrystals, is extended to microstructures with…

Graph Transformer-Based Flood Susceptibility Mapping: Application to the French Riviera and Railway Infrastructure Under Climate Change

Increasing flood frequency and severity due to climate change threatens infrastructure and demands improved susceptibility mapping techniques. While traditional machine learning (ML) approaches are widely used, they struggle to capture spatial…

Calibration of non-local damage models from full-field measurements: Application to discrete element fields

Continuous damage models are increasingly used in numerical simulations to design structures, but their local formulations are sensitive to mesh size and present localization of strains in an infinitely thin region. To overcome these problems non…
