Boundary-Free Contextual Biasing: Depth-Adaptive Gating and Reading-Space Matching for Unsegmented Languages
Muhammad Huzaifah, Yu Pan, Zachary Yeo +2
Contextual biasing supplies an ASR system with a list of expected words at inference time, but existing methods rely on word boundaries that Japanese and Chinese do not provide. We…
An extended deep energy method for thermo-mechanical crack propagation
Han Zhang, Mehrisadat Makki Alamdari, Babak Shahbodagh +4
Thermo-mechanical fracture couples transient heat conduction on a cracked domain with a crack that grows as the temperature and the displacement evolve. Neural energy solvers have…
A Vehicle-Integrated Approach to Digital Twin Deployment for Bridges Through Drive-By Sensing
Zihao Liu, Daigo Kawabe, Jiaji Wang +2
Ageing bridge infrastructure is a growing global concern, yet conventional Structural Health Monitoring (SHM) systems are costly and difficult to scale, and routine visual inspecti…
A Vehicle-Integrated Approach to Digital Twin Deployment for Bridges
Mehri Alamdari, Zihao Liu, Jiaji Wang +2
The project A Vehicle Integrated Approach to Digital Twin Deployment for Bridges is developing a scalable framework for bridge condition assessment using vibration measurements fro…
A mesh-free multiresolution deep energy method with phase-field modeling of brittle fracture
Han Zhang, Mehrisadat Makki Alamdari, Babak Shahbodagh +4
Phase-field modeling of brittle fracture removes the need to track cracks explicitly by recasting their evolution as the minimization of an energy functional. In return it requires…
Output-only road roughness identification from vehicle axle accelerations through a universal smoothing method
Zihao Liu, Daniel Dias-da-Costa, Tommy Chan +3
This paper presents an output-only method to identify road roughness profiles from axle accelerations of a moving vehicle. A two degree of freedom half-car model is discretised wit…
Development and Field Validation of a Fully Customised Vehicle Scanning System on Two Full-Scale Bridges
A. Calderon Hurtado, J. Xu, R. Salleh +2
Ensuring the structural integrity of bridges is essential for maintaining infrastructure safety and promoting long-term sustainability. In this context, Indirect Structural Health…
Simultaneous Energy Harvesting and Bearing Fault Detection using Piezoelectric Cantilevers
P. Peralta-Braz, M. M. Alamdari, C. T. Chou +2
Bearings are critical components in industrial machinery, yet their vulnerability to faults often leads to costly breakdowns. Conventional fault detection methods depend on continu…
Design of Piezoelectric Metastructures with Multi-Patch Isogeometric Analysis for Enhanced Energy Harvesting and Vibration Suppression
Patricio Peralta-Braz, Mehrisadat Makki Alamdari, Mahbub Hassan +1
Metastructures are engineered systems composed of periodic arrays of identical components, called resonators, designed to achieve specific dynamic effects, such as creating a band…
A New Architecture for Energy Efficient Fault Detection Using Energy Harvesters
Dongti Zhang, Patricio Peralta-Braz, Chun Tung Chou +3
The current battery-powered fault detection system for vibration monitoring has a rather limited lifetime. This is because the high-frequency sampling (typically tens of kilo-Hertz…
Optimal design of Piezoelectric Energy Harvesters for bridge infrastructure: Effects of Location and Traffic Intensity on Energy Production
Shaui Yao, Patricio Peralta-Braz, Mehri Makki Alamdari +3
Piezoelectric energy harvesters (PEHs) can be used as an additional power supply for a Structural Health Monitoring (SHM) system. Its design can be optimised for the best performan…
On the Joint Optimization of Energy Harvesting and Sensing of Piezoelectric Energy Harvesters: Case Study of a Cable-Stayed Bridge
Patricio Peralta-Braz, Mehrisadat Makki Alamdari, Rafael O. Ruiz +2
Piezoelectric Energy Harvesters (PEHs) are typically employed to provide additional source of energy for a sensing system. However, studies show that a PEH can be also used as a se…
Design optimisation of piezoelectric energy harvesters for bridge infrastructure
Patricio Peralta-Braz, Mehrisadat Makki Alamdari, Rafael O. Ruiz +2
Vibrational energy harvested from the bridge excitation due to the traffic flow or the wind load can be supplied to sensors in a Structural Health Monitoring (SHM) system and help…
On Physical Realizability for Inverse Structural Designs: Bounding the Least Eigenvalue of an Unknown Mass Matrix
P. Cheema, M. M. Alamdari, G. A. Vio
In the field of structural engineering analysis, a common requirement is to calculate the modal frequencies of a structure that has undergone an update, either naturally (such as f…
New Approaches to Inverse Structural Modification Theory using Random Projections
Prasad Cheema, Mehrisadat M. Alamdari, Gareth A. Vio
In many contexts the modal properties of a structure change, either due to the impact of a changing environment, fatigue, or due to the presence of structural damage. For example d…
