A parsimonious model for the proportional control valve
, 2001 A generic non-linear dynamic model of a direct-acting electrohydraulic proportional solenoid valve is presented. The valve consists of two subsystems-s-a spool assembly and one or two unidirectional proportional solenoids.

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.Insect‐scale crawling robots can traverse confined environments; nevertheless, their functionalities are predominantly restricted to sensing because of challenges in integrating actuated degrees of freedom. Herein, a miniature rotary electrostatic clutch is presented by incorporating cutting patterns in the clutch layer.

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.Female desert locusts dig underground to lay their eggs. They displace soil, rather than removing it, to create a tunnel. We analyze burrowing dynamics and 3D kinematics and design a locust‐inspired hybrid soft–stiff robot that reproduces this mechanism. The results show the natural strategy minimizes energy, whereas alternative patterns raise costs up

Failure Mechanism of Asymmetric Large Deformations Under Repeated Mining in Roadways
Energy Science &Engineering, Volume 14, Issue 3, Page 1195-1212, March 2026.Principal stress‐evolution diagram at different advance positions of 42205 working face. ABSTRACT To address the challenge of controlling severe asymmetrical deformation in roadways subjected to repeated mining, this study (i.e., based on the engineering context of the Buertai Coal Mine) investigated the characteristics of the regional stress field in ...
