Landslide Drag Forces on Pipelines
Soils and Foundations, 1991 ABSTRACT An experimental program was carried out to investigate the effect of landslide (or mudslide) velocity on the drag force applied by the sliding soil on a pipeline crossing the landslide area. Methods currently used in assessing drag forces are reviewed and compared to the experimental results.

Fold Walker: An Origami‐Inspired Quadruped Robot for Multipattern Locomotion and Object Grasping
Advanced Robotics Research, EarlyView.This article presents Fold Walker, an origami‐inspired quadruped robot capable of multipattern locomotion and object grasping. With each leg featuring two rotational folds, the robot can transform from a flat 2D configuration into complex 3D poses. Furthermore, its trunk and legs can be one‐shot 3D printed as a unified structure, greatly simplifying ...
