FBG-BASED VIBRATION SENSOR USING GRAVITY EFFECTS FOR LARGE INFRASTRUCTURES
FBG accelerometer vibration sensor smart infrastructure
2008/12/25
A simple mechanism for a vibration sensor based on fiber Bragg grating (FBG) is proposed. The mechanism utilizes the gravity force to allow the maximum sensitivity of the sensor into vertical directi...
A METHOD TO REMOTELY MEASURE MICROTREMORS FOR VIBRATION DIAGNOSES OF RAILWAY STRUCTURES
LDV remote measurement microtremor vibration diagnosis railway viaduct
2008/12/22
An accurate method for remotely measuring structure microtremors is proposed by using an improved Laser Doppler Velocimeter (LDV). The remote microtremor measurements of a rigid-frame structure model...
VIBRATION-BASED DAMAGE DETECTION IN FLEXIBLE RISERS USING TIME SERIES ANALYSIS
flexible riser damage detection time series analysis AR-ARX prediction model
2008/12/19
In this paper, a statistical pattern recognition method based on time series analysis is implemented in flexible risers. This method uses a combination of Auto-Regressive (AR) and Auto-Regressive with...
