Functional methods usually allow for a flexible and accurate representation of joint kinematics and are increasingly implemented both for clinical and biomechanics research purposes This paper presents a quantitative comparison between two widely adopted methods for functional axis estimation that is the helical axis theory and the symmetrical axis of rotation
Comminution by gyratory crusher is the first stage in the size reduction operation in mineral processing In the copper industry these machines are widely utilized and their reliability has
The results also proved the helical turbine had better self starting ability and a lower torque ripple than the straight bladed turbine It was ultimately concluded by Shiono et al that the helical blade water turbine is better at starting while the straight blade water turbine is better in energy production [58]
