Application of Microbially Induced CaCO3 on the Reinforcement of Rock Discontinuity
Applied SciencesMicrobially induced calcium carbonate precipitation (MICP) is a technique used in geotechnical engineering to reinforce soil and rock. While it is commonly used for soil reinforcement, its application for rock reinforcement in saline–alkaline ...

Strength of jointed rock masses [PDF]
Géotechnique, 1983 Jointed rock masses comprise interlocking angular par- ticles or blocks of hard brittle material separated by discontinuity surfaces which may or may not be coated with weaker materials. The strength of such rock masses depends on the strength of the intact pieces and on their freedom of movement which, in turn, depends on the number, orientation ...

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion
Advanced Robotics Research, EarlyView.A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Experimental study on acid erosion behavior of artificial rock joint plugged by MICP method
Yantu gongcheng xuebaoThe microbially induced calcite precipitation (MICP) method has been widely used for rock mass and soil reinforcement, but the researches on its acid erosion durability are rarely reported. Therefore, the acid erosion tests on the MICP-treated artificial
