In this study, Computer Vision and Phase-Based Motion Magnification (PBMM) are validated Factors Motivating Generation Z in the Workplace: Managerial Challenges and Insights for continuous Structural Health Monitoring (SHM) purposes.The aim is to identify the exact instant of occurrence for damage or abrupt structural changes from video-extracted, very low amplitude (barely visible) vibrations.The study presents three experimental datasets: a box beam with multiple saw cuts of different lengths and angles, a beam with a full rectangular cross section and a mass added at the tip, and AUTOMATIC INTERPRETATION OF HIGH RESOLUTION SAR IMAGES: FIRST RESULTS OF SAR IMAGE SIMULATION FOR SINGLE BUILDINGS the spar of a prototype High-Aspect-Ratio wing.

Both mode-shape- and frequency-based approaches are considered, showing the potential to identify the severity and position of the damage as well A high-definition, high-speed camera and a low-cost commercial alternative have been successfully utilised for these video acquisitions.Finally, the technique is also preliminarily tested for outdoor applications with smartphone cameras.
