Xu Guangtong et al. [6] proposed a method to define the physical property of diesel-fuel with NIR spectral technique, including density, refractive index, flash point, distillation range and solidifying point.
It is necessary to extract optimum factors for factor score matrix (T=XW) computing from a set of response and predictor variables linearly dependent partially before computing the weight matrix and linear regression modeling (Y=TQ+E, Q is the regression coefficient of matrix T, E is the deviation matrix).
The are known as hyperparameters which will affect the reliability of GP performance directly.

Pure water base fluid and various nanoparticles selected in this study as the working fluid, and the thermophysical properties assumed to be constant.
The physical and thermal properties of base fluid and nanoparticles at the base temperature have been summarized in Table 2.
The change of type of nanoparticle completely modifies the thermophysical properties of the nanofluid thus it directly affects the heat transfer through the annulus.
In general, the Nusselt number increase with volume fraction increase, so it increases when chose a better nanoparticle type corresponding to thermophysical properties.

In this case a proper treatment is essential to improve its geotechnical properties.
Since MC was fixed at 2LL for this study, then the dominant factor is the cement content.
According to Lorenzo and Bergado (2004) [3], yield stress is gov-erned by the after curing void ratio which affects the packing of the solid particles.

Frenkel’s formula of theoretical strength reveals the importance of defects in governing the mechanical properties of materials, and it was believed for many decades that theoretical strength is unimportant technologically since we are usually dealing with defected, not ideal, materials.
The nucleation and migration of defects can be aided by thermal fluctuations [1,2], a factor not considered in simple “brute-force” strength estimates.
Properties of nano-scale systems, for example, the hardness of epitaxial thin films measured by nano-indentation, can be closer to the properties of ideal single-crystals and differ considerably from the macroscale properties of that material.
Note xx xx xx that the decrease in e * by roughly factor of three (from e * □ 0.06 to e * □ 0.02 ) due to increase in D means the one order of magnitude decrease in the critical elastic energy.
We always applied homogeneous tension/compression parallel to surface and thus, changing the crystallographic orientation of the sample, we changed not only the structure of the surface but also the orientation of the slip systems with respect to the loading axis (Schmidt factor).

Consequently, the most important factor to ensure the glasses’ high quality is an efficient defect detection method on the basis of strict glasses’ quality grading requirement.
Some part of the pollutants can be removed through image processing, but other pollutants which cannot be removed will affect the accuracy of detection.

During the refinement procedure, the mechanical fields are simply induced from the current mesh to the new mesh.
During the coarsening procedure, the mechanical fields associated to four associated elements are averaged and the result is associated to the new element.
Properties of the used material (steel E24), are summarized in Table 2.
In order to control deformation, it is necessary to change the stress state inside the blank that is affected by many factors such as the blank size and the blank holder force.
