Cavitation detection based on instantaneous angular speed
Proceedings of the International Conference on Condition Monitoring and Asset Management, 2023 The study and detection of cavitation in hydraulic turbo-machinery has gained recently particular attention from both manufacturers and end users, due to the damage caused on machines’ surfaces that may result in costly sudden shutdowns. The traditional cavitation detection approaches exploit the noise and vibration signals that sense the vapor bubble

‘Whip from the hip’: thigh angular motion, ground contact mechanics, and running speed
Biology Open, 2020 During high-speed running, lower limb vertical velocity at touchdown has been cited as a critical factor needed to generate large vertical forces. Additionally, greater leg angular velocity has also been correlated with increased running speeds. However,

Thickness variation parameter in a thin rotating disc by finite deformation [PDF]
FME Transactions, 2013 Seth’s transition theory is applied to the problems of thickness variation parameter in a thin rotating disc by finite deformation. Neither the yield criterion nor the associated flow rule is assumed here.

High-speed acoustic communication by multiplexing orbital angular momentum [PDF]
Proceedings of the National Academy of Sciences, 2017 Significance Acoustic communication is critical for underwater application such as deep-ocean scientific explorations and off-shore industrial controls. This is because other techniques using electromagnetic waves are difficult for underwater applications due to the strong absorption of water. Optical communication, on the other hand, suffers

Natural roller bearing fault detection by angular measurement of true instantaneous angular speed [PDF]
Mechanical Systems and Signal Processing, 2010 The challenge in many production activities involving large mechanical devices like power transmissions consists in reducing the machine downtime, in managing repairs and in improving operating time. Most online monitoring systems are based on conventional vibration measurement devices for gear transmissions or bearings in mechanical components.
