Robust Analysis of Various Measurement Uncertainty Parameters in Rebound Hammer Test
Indian Journal Of Science And Technology, 2023 Abstract Objective: The major objective of the proposed work is to determine the concrete’s expected compressive strength by evaluating the consistency of concrete using Rebound Hammer Test. Further, the determination of the quality of one component of the concrete relates to the quality of another component based on the concrete meeting criteria ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
