Crane Safety Assessment Method Based on Entropy and Cumulative Prospect Theory
Entropy, 2017 Assessing the safety status of cranes is an important problem. To overcome the inaccuracies and misjudgments in such assessments, this work describes a safety assessment method for cranes that combines entropy and cumulative prospect theory. Firstly, the

A Multi‐Mode Analytical Frequency Modulation Input‐Shaping Control
International Journal of Mechanical System Dynamics, Volume 5, Issue 3, Page 415-425, September 2025.ABSTRACT In rest‐to‐rest maneuvers, input shapers like the double step (DS), zero vibration (ZV), and zero vibration derivative (ZVD) are widely utilized to eliminate residual vibrations in single‐mode systems. These shapers can be used to eliminate residual oscillations in multimode systems, given that the higher frequencies are odd multiples of the ...
