Research on Dynamic Characteristic of Rudder Transmission System with Multiple Clearance Joints

open access: yesXibei Gongye Daxue Xuebao, 2020
In order to meet the characteristics including small clearance, heavy load and large contact area of joints existed in rudder transmission system, a new normal contact force model is established, which is suitable for the large-area contact process and ...

Design and Analysis of Vibratory Mechanism for Tillage Application

open access: yesOpen Agriculture, 2018
Tillage operations play an important role in soil manipulation processes. This paper aim to design a vibratory mechanism for agricultural tillage operation which would provide the desired motion and path to the cutting tool in the soil.

Design of a Dynamically Balanced 2-DOF Planar Parallel Manipulator using Four-bar Legs [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2017
A mechanism is reactionless or dynamically balanced when there is no shaking force and shaking moment applied to the base during mechanism movement. The theory for designing reactionless 2 degree-of-freedom (DOF) planar parallel manipulator is discussed ...

The ADAM metalloproteinases

open access: yesMolecular Aspects of Medicine, 2008
The ADAMs (a disintegrin and metalloproteinase) are a fascinating family of transmembrane and secreted proteins with important roles in regulating cell phenotype via their effects on cell adhesion, migration, proteolysis and signalling. Though all ADAMs contain metalloproteinase domains, in humans only 13 of the 21 genes in the family encode functional

Efficient-Adam: Communication-Efficient Distributed Adam

open access: yesIEEE Transactions on Signal Processing, 2023
Distributed adaptive stochastic gradient methods have been widely used for large-scale nonconvex optimization, such as training deep learning models. However, their communication complexity on finding $\varepsilon$-stationary points has rarely been analyzed in the nonconvex setting.
