The temperature control system allows different cooling temperature settings, which contributes to grain nucleation and prohibits the growth of grains.
Figure 1 shows that L* is Lightness, which represents lightness value, and the numbers from high to low represent the lightness from light to dark. a* is the green/red axis, and the number from high to low represents the color from red to green. b* is the blue/yellow axis, and the number from high to low represents the color from yellow to blue.

Also obtaining new data may be beneficial to understand the behavior of geosynthetics particularly in engineering projects where the use of fine grained soil is of prime concern.

In essence, the requirements of business differentiation will eventually be mapped to more fine-grained division and combination of underlying IT resources.
Obviously, HSE 1.0 architecture does not present such a fine-grained resource management capabilities.
Customization Layer could construct a cluster of VM instances based on resource requirements (eg: CPU number, memory size, software type, etc).
The overlapping of communities makes a more fine-grained resource sharing possible.
Given the number of simultaneous software instances with a license normally limited, negotiant allows that user with high priority will get license first when license requests from enterprises conflict.

The HRTEM establishes a complex morphology with grains and sub-grains with a minimum size of about 80 nm [12].
According to the Basquin law, the asymptotic stress for an “infinite” number of working cycles approaches 170 MPa.
The former ones are associated to the interaction between the interface displacements and the dislocations, the grain surfaces and so on.
The first one is realized in the cable number 1 of the ELSA-JRC-EU facility (Fig. 11).

The helium atoms are insoluble in the metal, which may cause lattice distortion and high internal stress in the material, meanwhile they are easily be trapped at grain boundaries, dislocations, and other defects and aggregated into bubbles.
When the temperature is high, He will segregate near the grain boundary and reduce the grain boundary strength to cause non-hardening embrittlement of the material [1].
By removing all of the atoms (whose numbers denote as S) within a spherical region with the desired diameter, then inserting certain helium atoms (whose numbers denote as M) in this region with a percentage (M/S), the helium bubble with He/V ratio M/(S-M) was created.
The increase of yield strength due to these irradiation defects, can be expressed as (3) where is the yield strength increasement, M is the Taylor factor, is the increase of CRSS and it can be expressed as (4) where μ is the shear modulus of the matrix BCC Fe (80GPa), is the Burgers vector (0.249nm), N and D are number density and diameter of helium bubble, respectively.
Wang Ji [18] apply α values of 0.4 for He bubbles with diameter of 1.7-3.56 nm and 0.25 for dislocation loops, based on the dispersed barrier-hardening(DBH) model and TEM analysis results of defects size and number density, to predict the hardness increment at 300℃ and 450℃.

Mean field theory made in terms of several surface integrals is also used to coarse grain the molecular interactions between molecules resulting in rapid computational speed.
The cavity of graphene sheet comprises both the bulk and absorption regimes, from which the usual van der Waal equation could be used to deduce the number density of CO2 in the bulk regime while the multi-scale technique has to be incorporated into the modified van der Waals equation to take into account the interactions between molecules.
Theory Here, double layered graphene sheets are considered and we assume the carbon atoms are smeared across the surface of graphene so that mean field theory could be used to approximate the pairwise interactions between CO2 and the host structure, which is given by Eh=ηπ-A21h4+1S-h4+B51h10+1S-h10, (1) where η, A, B, S and h denote the number density of carbon atoms on graphene, the attractive constant, the repulsive constant, the separation between two graphenes and the height S ≥ h ≥ 0, respectively.
The total number density of CO2 in the system is therefore n=nad+nbulk.
However, the number density given by Eq. (3) suffers from singularities when the temperature T becomes zero or the external pressure P becomes infinity, which is physically infeasible.
