Vibration-Based Structural Health Monitoring Using Piezoelectric Transducers and Parametric t-SNE

Application of Piezoelectric Transducers in Structural Health Monitoring Techniques

Structural health monitoring using piezoelectric impedance measurements.

This paper presents an overview and recent advances in impedance-based structural health monitoring. The basic principle behind this technique is to apply high-frequency structural excitations (typically greater than 30kHz) through surface-bonded piezoelectric transducers, and measure the impedance of structures by monitoring the current and voltage applied to the piezoelectric transducers. Cha...

Design of Embedded Piezoelectric Transducers for Structural Health Monitoring in Concrete Structures

In the last decades the field of structural health monitoring and damage detection has been intensively explored. Active vibration technique allows to excite the structure at high frequency vibrations which are sensitive to small damage. Ideal candidates for the generation of high frequency (ultrasonic) signals are piezoelectric PZT transducers, due to their small size, low cost and large bandw...

Parametric nonlinear dimensionality reduction using kernel t-SNE

Novel non-parametric dimensionality reduction techniques such as t-distributed stochastic neighbor embedding (t-SNE) lead to a powerful and flexible visualization of high-dimensional data. One drawback of non-parametric techniques is their lack of an explicit out-of-sample extension. In this contribution, we propose an efficient extension of t-SNE to a parametric framework, kernel t-SNE, which ...
