Mismatched ZN-type worm pair meshing theory

open access: yesAdvances in Mechanical Engineering
Cylindrical worms are sensitive to errors; mismatch can solve this problem. However, applying the finite element method to calculate the meshing characteristics of mismatched worm pairs has several limitations. Therefore, the meshing theory of mismatched

Design and Analysis of Internal–External Composite Meshing Hy-Vo Chain

open access: yesApplied Sciences, 2023
The internal–external composite meshing mechanism should be the best way to improve the transmission performance of a silent chain drive, but there is no internal–external composite meshing Hy-Vo chain under the classical design approach.

Study on the Nonlinear Dynamic Behavior of Rattling Vibration in Gear Systems

open access: yesMachines, 2022
To reveal the nonlinear dynamic behavior of gear rattling vibration caused by gear backlash, a 2-DOF oscillator model with spring and damping elements was established. Based on the theory of discontinuous dynamical systems, the phase plane of gear motion

Research on the sliding friction associated spur-face gear meshing efficiency based on the loaded tooth contact analysis. [PDF]

open access: yesPLoS ONE, 2018
In order to solve the problem of Meshing Efficiency of spur-face gear sliding friction, a method for calculating the Meshing Efficiency of Spur-Face gear is proposed based on Elastohydrodynamic lubrication (EHL) theory. Through the Tooth Contact Analysis

A compression strategy for particle mesh Ewald theory

open access: yesThe Journal of Chemical Physics, 2021
Particle Mesh Ewald (PME) has become a standard method for treating long-range electrostatics in molecular simulations. Although the method has inferior asymptotic computational complexity to its linear scaling competitors, it remains enormously popular due to its high efficiency, which stems from the use of fast Fourier transforms (FFTs).

On union ultrafilters [PDF]

open access: yes, 2011
We present some new results on union ultrafilters. We characterize stability for union ultrafilters and, as the main result, we construct a new kind of unordered union ...

Laws, Causation and Dynamics at Different Levels [PDF]

open access: yes, 2011
I have two main aims. The first is general, and more philosophical (Section 2). The second is specific, and more closely related to physics (Sections 3 and 4).

Matrix transpose on meshes: theory and practice

open access: yesProceedings 11th International Parallel Processing Symposium, 2002
We consider the problem of matrix transpose on mesh-connected processor networks. On the theoretical side, we present the first optimal algorithm for matrix transpose on two-dimensional meshes.  Then we consider issues on implementations, show that the theoretical best bound cannot be achieved and present an alternative approach that really ...

Active mesh coding and rate-distortion theory [PDF]

open access: yesProceedings of 3rd IEEE International Conference on Image Processing, 2002
This paper presents a video coding scheme for very low bit rate applications. The coding approach relies on active meshes and can be viewed as a particular case of region-based coding. The active mesh is used to efficiently represent and code the various regions of the scene and the motion information.
