... to their large size, high attenuation, and low signal-to-noise ratio. However, concrete facilities vibrate due to ambient excitations such as vehicle movement, wind, and water flow. These ambient vibrations can be utilized in amplifying CAN. For example, a vehicle can be moved at a particular velocity over...

... which results in a substantial increase in kurtosis and impulse factor of the vibration signal. The scheme constitutes a series of operations. In the beginning, the raw signal is decomposed by ensemble empirical mode decomposition (EEMD) and inverse filtering (INF). The above two stages of signal...

... and signal processing techniques are used to extract features and final information regarding the machine performance. One type of the primary data that can be obtained from a system is the vibration responses of the system. Vibration responses of dynamical systems are usually nonstationary signals...
