The main principle of vibration-based damage detection in structures is to interpret the changes dynamic properties structure as indicators damage. In this study, mode shape index (MSDI) method was used identify discrete damages plate-like structures. This based on difference between modified modal displacements undamaged and damaged state structure. order assess advantages limitations proposed...

This paper develops methods for detecting discrimination by individual employers using correspondence experiments that send fictitious resumes to real job openings. We establish identification of higher moments the distribution job‐level callback rates as a function number sent each and propose shape‐constrained estimators these moments. Applying our three experimental data sets, we find striki...
