Introduction It is important for the concrete industry to need moisture sensors in the sand bins or in the concrete bins because mix design assumes that aggregates, cement and water are present in the correct proportions, according to the dry material weights.
However, the moisture in the sand varies largely and the sand that get from river bed usually mix other material such as mud.

Introduction Because of the synthetic excellent mechanical properties of high hardness, low friction coefficient, high temperature resistance, (Ti, Al) N film is one of the most widely used film materials on the process research and application.[1-6] Many experts and scholars at home and abroad for its single process parameters (such as: arc current, substrate negative bias, transition layer type and thickness, nitrogen and argon gas partial pressure of the magnetic field strength, target based distance, temperature, etc.) has done a lot of testing and analysis on the impact of the hardness of titanium nitride film and film and substrate binding force.[7-10] But, the links between the various process parameters and the relationship between primary and secondary effects of titanium nitride films have rarely been reported.

However, modeling nonlinear friction dynamics is not straightforward manners, since the friction is a result of complex interactions between the surface and near-surface regions of the two interacting materials as well as other substances present such as lubricants.
