A comparative experimental study on the diagnostic and prognostic capabilities of acoustics emission, vibration and spectrometric oil analysis for spur gears [PDF]
, 2007 Prognosis of gear life using the acoustic emission (AE) technique is relatively new in condition monitoring of rotating machinery. This paper describes an experimental investigation on spur gears in which natural pitting was allowed to occur.

An experimental method to measure gear tooth stiffness throughout and beyond the path of contact [PDF]
, 2001 A method is presented that allows the accurate measurement of the tooth pair stiffness of a pair of spur gears. The method reveals the stiffness behaviour throughout the full length of the normal path of contact and also into the extended contact region ...

A Thickness-Invariant Origami Robot With Integrated Actuation and Multimodal Locomotion. [PDF]
Adv Sci (Weinh)A thickness‐invariant variation on the Yoshimura origami pattern is used as the basis of a robot, allowing power, actuation, and control systems to be embedded within the thickened panels of the pattern. The robot uses multiple kinematic branches to achieve distinct modes of locomotion, such as walking, running, galloping, and turning. ABSTRACT Origami

Generalized Dystonia With Cervical Predominance in a Patient With a De Novo TCF20 Variant
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT TCF20 has been implicated in developmental delay and intellectual disability, with dystonia reported less frequently. We describe a woman in her early twenties with childhood‐onset learning difficulties, progressive dysarthria, tremor, and generalized dystonia with marked cervical predominance, associated with a de novo TCF20 frameshift ...

Design of a cost-effective magnetic gearbox for an aerospace application
The Journal of Engineering, 2019 Magnetic gears are designed to perform in a highly reliable manner, and offer several advantages compared to mechanical gears but difficulties with manufacturing techniques and cost are strong handicaps. In contrast to conventional gears, the contact and
