This paper presents a comparison of the statistics on the measured modal parameters of a bridge structure to the expected changes in those parameters caused by damage. It is then determined if the changes resulting from damage are statistically significant. This paper considers the most commonly used modal parameters for indication of damage: modal frequency, mode shape, and mode shape curvatur...

Predation can cause morphological divergence among populations, while ontogeny and sex often determine much of morphological diversity among individuals. We used geometric morphometrics to characterize body shape in the livebearing fish Brachyrhaphis rhabdophora to test for interactions between these three major shape-determining factors. We assessed shape variation between juveniles and adults...

Most research on computer vision (CV)-based vibration measurement is limited to the determination of discrete or coarse mode shapes structure. The continuous edge structure in images has rich optical features, and thus, by identifying tracking movement structure’s edge, it possible determine high-resolution full-field without a preset target. present study proposes CV-based method shape identif...
