9510683 Peterson This GOALI (Graduate Student Industrial Fellowship) award is made to evaluate a new technique for obtaining the velocity of an ultrasonic wave in concrete. Due to the low signal to noise ratio in oncrete, the conventional ultrasonic analysis methods are frequently inadequate. The use of wavelet decomposition of the ultrasonic signal may provide more details on the dispersion characteristics and thereby improved time of flight data. ***

这个GOALI（研究生工业奖学金）奖是为了评估一种获得混凝土中超声波速度的新技术。由于混凝土的信噪比较低，传统的超声分析方法往往存在不足。对超声信号进行小波分解可以提供更多关于频散特性的细节，从而改善飞行时间数据。＊＊＊
