Leaks of these pipelines can cause serious consequences, such as considerable product losses, environmental pollution if the materials conveyed are poisonous, among others.
The velocities of these modes are dispersive in that they depend not only on the material elastic properties and density, but also on the frequency.
There have been intensive research activities in the application of wavelets in various fields of science and engineering.
The velocities of these modes are dispersive in that they depend not only on the material elastic properties and density, but also on the frequency.

In consideration of these features, ceria-containing materials have attracted widely attention as SCR catalysts for NOx decrease both in stationary and mobile sources.
It is worth noting here that the above reactions took place at mixed solution of the alcoholic and deionized water, for the reaction rate could be slowed down due to a high viscosity of ethanol, which may result in a lower nucleation rate in the reaction system to form loosened and porous materials.
