Periodic inspection of concrete structures for detecting internal defects through
nondestructive imaging is recommended for ensuring structural safety and integrity …

Accurately identifying, localizing, and characterizing internal defects is crucial for ensuring
the safety and durability of concrete structures. While impact echo (IE) is a highly promising …

Traditional signal processing methods cannot effectively segment the optimal frequency
band, resulting in the fault characteristics are not obvious. Therefore, this paper proposes a …

To improve the mode decomposition capacity of the empirical Fourier transform for time-
varying structures, an empirical multi-synchroextracting decomposition method has been …

Ultrasonic gas flowmeters employ non-intrusive measurement techniques, characterized by
rapid responsiveness and exceptional anti-interference capabilities. These attributes not …

The large amount of data collected by structural health monitoring systems deployed in the
bridge contains dynamic information about the structure. To enhance the prediction …

This study proposes a method to predict applied loads on bonded structures via non-
destructive testing results. Various types of concrete, such as high-performance alkali …

Anomaly detection is crucial for condition monitoring of robot joints. An increasing number of
anomaly detection methods based on deep learning have been investigated. However …

Symplectic geometry mode decomposition (SGMD) method takes the Hankel matrix as the
trajectory matrix, and the eigenvalue of trajectory matrix can be obtained by symplectic …

Concrete piers are the key load-bearing components of wading bridges. Most detection
