Efficiency Let k be the number of attributes with respect to identity ID. p is bilinear pairing in G1. sk denotes private key.
In addition, the number of group elements in a private key or in a signature grows linearly with the size of the identity.

The required water /powder ratio is determined by conducting a number of trials [15,16].
Number of trail mixtures was tried for their permissible limits, and then the final proportions of ingredients and admixtures have been finalized for M20 Grade concrete with water cement ratio 0.4.

Currently, the number of agricultural subjects managing their land, pastures and fields used for the production of livestock and crops is decreasing.
The number of livestock is decreasing more quickly than the volume production of crops such as barley, wheat and corn.
After an effective harvest, mainly grain from crops is used.

As is well known, granite process industry generates a large number of wastes, due to the sawing and polishing processes.
The non-isothermal crystallization kinetics of glass can be described by the Kissinger equation[11] expressed as (1): (1) where α is the heating rate, R is the gas constant, and C is the constant number.
A lot of small grains occurred in the alkali-leached surfaces.

A number of requirements are imposed on medical materials, which can be divided into three groups: 1.
Alloy Ti-6Al-4V has a globular (α + β) -structure (Fig. 1 b), and in alloy 316L, a typical single-phase structure is formed, represented by polyhedral grains of the γ-phase (Fig. 1 c).
The lowest plasticity is observed in the cobalt alloy, which is apparently due to the cast state and the presence of a large number of intermetallic phases and chromium carbide.

Such as bamboo can be used in the make of scaffold, building a house； Straw small but can shore up the big grain,And when is suffered from the wind force function is generally broken in the root, It is shown that has very good compression and lateral force resistance ability.
Select 8 node Solid45 number unit that can better simulation entity plastic, creep, large deflection, etc free mesh With the default level 6 accuracy,Get finite element model of the table.
Modal analysis is mainly used to determine the vibration characteristic of institutions or machine parts,Mainly is the inherent frequency and vibration mode,At the same time is the basis of other dynamics analysis,Such as harmonic response analysis ,Transient dynamics analysis and spectrum analysis, and so on. choose Block Lanczos method when we analysis,also select Solid95 number unit.

In our previously papers, the method has been used successively to calculate the vacancy diffusion in the bulk and surface of pure metals [18, 19], the surface energy [20, 21], the grain boundary energy [22] and the interfaces energy [23].
Calculation process and results In order to simulate half-infinite Cu3Ag ordered alloy (001) surface with an isolated vacancy, the periodic boundary condition can be applied to reduce the number of atoms for representing the structure and a computational cell with 930 atoms was used which was surrounded by a mantle of atoms, in which is the lattice constant of Cu3Ag that is 3.77 Å.
In order to facilitate expression, the atoms are labeled with Cu (red balls) or Ag (blue balls) together with their layer number from the top layer.
