Analyzing Modeled Torque Profiles to Understand Scale-Dependent Active Muscle Responses in the Hip Joint

open access: yesBiomimetics, 2022
Animal locomotion is influenced by a combination of constituent joint torques (e.g., due to limb inertia and passive viscoelasticity), which determine the necessary muscular response to move the limb. Across animal size-scales, the relative contributions

Performance improvement of the Sarcheshmeh Copper Complex Cu-Mo thickener using a vane type feedwell [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2019
Water plays a key role in mineral processing plants. In order to process one ton of ore, 2.5 ton water is needed. Thickeners are commonly used for dewatering and recovering the water in most mineral processing plants.

A new technique of cogging torque suppression in direct-drive permanent-magnet brushless machines [PDF]

open access: yes, 2010
In direct-drive electric propulsion systems, where there is no reduction gear to minimize and absorb the adverse effects of cogging torque generated by the permanent-magnet (PM) machine, minimization of cogging torque generation is of particular ...

Prediction of the electromagnetic torque in synchronous machines through Maxwell stress harmonic filter (HFT) method [PDF]

open access: yes, 2006
For the calculation of torque in synchronous motors a local method is analysed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air-gap.

Effect of the Grip Angle on Off-Spin Bowling Performance Parameters, Analysed with a Smart Cricket Ball

open access: yesProceedings, 2018
In the off-spin bowling grip, the ball is clamped between index and middle fingers. Spin bowlers attempt to select a spread angle between these two fingers that achieves comfort and optimises performance.
