The soliton propagating in a horizontal granular chain with Hertzian contact damps due to graity in a vertical chain. We find that the type of damping is power-law in depth and the exponent of power-law for the amplitude approaches −1/12 for weak impulse. We also show that other quantities such as grain velocity, kinetic energy, and number of grains participating to signal as well as phase and ...

The contact angle of a macroscopic droplet on a heterogeneous but flat substrate is studied using the interface displacement model which can lead to the augmented Young-Laplace equation. Droplets under the condition of constant volume as well as constant vapor pressure are considered. By assuming a cylindrical liquid-vapor surface (meniscus) and minimizing the total free energy of the interface...

abstract: in the present paper, we give a necessary and sufficient condition for contact cr-warped product to be contact cr-product in kenmotsu space forms.

A compufer software has been developed for the analysis and design of fixtures. This software can lead the designer to the optimal design of the fixturing system , which minimizes the total work done on the workpiece, the fixturing force, rhe deformation index, or the maximum effective stress. The workpiece is modeled as a j linear isotropic elastic solid. The machining forces are simulated by ...

We study the contact process on the complete graph on n vertices where the rate at which the infection travels along the edge connecting vertices i and j is equal to λwiwj/n for some λ > 0, where wi are i.i.d. vertex weights. We show that when E[w 2 1] < ∞ there is a phase transition at λc > 0 so that for λ < λc the contact process dies out in logarithmic time, and for λ > λc the contact proces...

This paper evaluates state-of-the-art contact models at predicting the motions and forces involved in simple in-hand robotic manipulations. In particular it focuses on three primitive actions—linear sliding, pivoting, and rolling—that involve contacts between a gripper, a rigid object, and their environment. The evaluation is done through thousands of controlled experiments designed to capture ...
