Because of the high relative velocity between the wheel and the workpiece, the peclet number is large enough, and the conduction in the moving direction is negligible.
Therefore, all the fluid, grain and the workpiece can be assumed to be a semi- infinite body.

In the practice, we may cover a shape with boxes with different scales and find how the number of boxes changes with the size ε of the boxes.

Utilization of industrial waste  to develop new cementing materials With the scale of industrial productions increasing, generation and accumulation of a large number of industrial waste and related problems such as storage, handling and destruction of the environment are becoming increasingly severe.

THE DESCRIPTION OF EMBEDDED SOFTWARE SYSTEMS An embedded software architecture is a « big grains» structure of a system.
The results of tokens movements in the Petri Network on matrix shape: Table1: Set of tangible states Table2: Average Number of tokens on a place The tool PIPE2 permits to have the execution times of PN: · State space exploration took 0,218s · Solving the steady state distribution took 0,172s · Total time was 0,499s Therefore, at the end of 0,499s (less than one second) the task is executed and the materials resources are again available (Speedy and availability of embedded system).

"Xunzi king"said that" the grass and the flower are in full bloom, and axe is not taken into the forest"; Wang Kwu poison does not enter the Ze"; " do not miss the opportunity in the four seasons of spring, spring, autumn, winter, then the grain for people is incessant."

Based on the number of factors and assumed levels, the orthogonal table L9 (34) was selected for experiment arrangement (shown in Table 4).

There are a great number of publications on research of recycling of demolished concrete, of which most are in regard to recycled aggregate (RA) made from demolished concrete [1-6].
The normally used mechanical process of breaking down blocks of demolished concrete into relatively small grains, may cause RA suffer internal damage such as micro-cracks [1-3] and RAC have relatively low strength [7].

is the dissipative interfacial stress and is modeled as=-υ(1+ψ)2(1-ψ)h/ 4w20, in which the constant h is 2.757. τ0/w0 is a dimensionless velocity, D=ατ0/w20 is the dimensionless thermal diffusivity, υ=υ0τ0/w0 is a dimensionless kinematic viscosity, Pr=υ/α is the Prandtl number, x and y are dimensionless distances, t is dimensionless time while ρ, P and are the density, pressure and flow velocity, respectively.
The grain grows into an equiaxial dendrite under free flow conditions whereas when U is 0.15 side–branches are formed upstream of the lateral principal branch and the longitudinal principal branch is smooth.

During the sealing materials, the IPG has excellent such as compact structure, small grain size and uniform performances.
In the process of precision cutting IPG, when cutting thickness is less than the critical thickness, the material is removed mainly through plastic deformation since there are a large number of dislocation movements inside the crystal material.
