The axial fan blades used in underground mines are usually manufactured in AlSi12CuMgNi alloy (EN AC 48000).They must have a high mechanical strength to withstand the stresses resulting from the rotation speed of the rotor and a high resistance to erosive wear caused by suspended particles from underground mining and transport operations.The aim of
The structure design scheme and the control method of a self-balancing cockpit system based on the principle of dual-axis gyro were proposed to solve the problem of improving maneuverability of special copyright platform under large roll and pitch motions.First, the structural modeling of the self-balancing cockpit system was completed by Creo, and
Carbonation of concretes is a natural physico-chemical process that can be described as a reaction between the carbon dioxide contained in the air and the cement matrix.Carbonation concerns all concretes types in contact with the ambient air but also concretes in ground, from production stage to use and end-of-life stages.The amount of carbon dioxi
Understanding the lower limb biomechanical characteristics of chronic ankle instability (CAI) individuals and copers could provide the insight into the mechanism of repetitive lateral ankle sprains (LAS).Thus, the aim of this study was to investigate the lower limb joint angles, joint moments, and joint stiffness among CAI, copers and healthy indiv
