The spatial discretization is needed as the contact area and the pressure distribution are a priori unknown and, moreover, keep changing during the contact process together with the mechanical response of the viscoelastic material.
To determine the time of collision, we connect the two bodies to a direct current source, and the current signal comes out in the contact process. For the investigated duration of 5 ms, the motion of both bodies can be considered as a free horizontal motion.
We adopt the framework of the small strain theory, we assume that the contact process is quasistatic and we study it in the interval of time [R.sub.+] = [0, [infinity]).
In the light of theory of the contact process and the above definitions, if [lambda] < [[lambda].sub.c], the virus will die out at last; namely, the influence on the stock price by the investors is limited.
Access to intelligent contact data can help improve the contact process not only as it relates to efficiency but as it relates to quality and brand loyalty--two equally important indicators that if improved upon, will help you achieve your goal of creating an intelligent contact center.
The above contact analysis shows that during the contact process, hexagon convex hull can embed the surface of belt and realize a certain extent of interlocking effect.
The disproportionate minority contact process allows us to go further in the examination of the juvenile justice system.
Ideally, follow-up activities will be executed during the contact process, while the customer is still on the line, or within seconds of the call's termination.
These results indicate that the technique of determining the contact angles by goniometry can be used to evaluate the adsorption process of polymers present in drilling fluids on the inside surfaces of metal pipes, since it produces quantitative results that are comparable with those obtained by visual observation, although not exactly reproducing the contact process of the fluid with the metal.

The contact process for the former and the electrolysis of sodium chloride brine for the latter two moved into the realm of technological demands that not even chemists and mechanical engineers in collaboration could handle.
