The Gabor wavelet is the important technique widely used in the areas of images recognition such as human face expression, it extract the more important grain features for face expression effective, but it does not take into account the relative changes in the important characteristics of each location of the point features.
The output layer has c output units, each output unit denoted by j (j=1, 2, …c, where 1≤c≤7 is the expression class number).
Supposing the training sample set is , c is the number of sample class(1≤c≤7), where each training sample has its corresponding actual output as (i=1, 2, …c).

The general grain size and crystal surface of the synthesized CuHCF active materials were confirmed from the scanning electron microscopy (SEM) images.
As shown in Figs. 1(a)–(d), the XRD profiles can be well indexed to standard CuHCF (JCPDS card number 86-0513) [20].

Number of Hit.
That is, this result is due to the elimination or restraint of closing of pores or friction between grains in accord with the increased confining pressure.
In comparison to granites, the number of AE was smaller and AE with high amplitude at 80% of peak stress was decrease in marble.
Sudden increase stress points of the number of hits can be easily found at each cycle, except the first cycle.
In the 2nd-5th cycles, a sudden increase stresses levels of the number of hits are almost correspond to maximum stress level of the previous cycles.

The number of loading cycles will be beyond 108 to reach in gigacycle region throughout the expected lifetime.
Simultaneously, grain boundaries can be weakened by irradiation and radiation-embrittlement can lead to crack formation when an irradiated material is subjected to stress loading [5].
It was proposed that this sudden increase of the temperature allows to determine the cycle number at crack initiation and more than 92% of the total life is devoted to the initiation of the crack.
Fig. 8 Relationship between stress amplitude and number of cycles Fig. 9 Relationship between the number of cycles and residual strength Residual Strength with Fatigue Damage.
It can be seen that the residual strength is independent of the number of cycles, and the difference of the residual strength between the specimen with fatigue damage and without fatigue damage can be negligible.

For the high mountains and steep on yunnan laterite area, there are a lot of lateritic slope, a long period in climate condition of warm, wet, more rainy and partial acid, In combined effects of underground water and infiltration of rainwater especially acid rain, will produce hydrolysis reactions and corrosion function to laterite particles and the connection among grains, leading to the composition of laterite happen migration with seepage flow, lead to the changes of macro and micro characteristics of slope laterite, lead to serious geological disasters.
(a) The effect of compaction energy or moisture content or temperature (b) The effect of immersion time Fig.2 The migration ability of iron ion in laterite in different effect factors The migration process of iron ion in laterite in water environment The migration process of iron ion in laterite is actually the process that adsorption iron ions in laterite grains surface dissolve and migrate into water solution in water environment.
With the extension of immersion time, the number of the iron ion migration out of the laterite is more and more large.
In the water environment especially seepage, the migration of iron ions directly affect to the linking performance between laterite grains, thereby affect to the structural stability of the laterite and even the occurrence and development of lateritic geological disasters.

The grain size distribution curve indicated that sediment is predominantly silt-sized with 60% of clay; the percentage of particles whose diameter is less than 80µm is about 78%, and tuff particle size lays mainly around 500 um, with neither fraction of particles below 5 um or above
1.25 mm.
The ceramic waste powder shows a completely different size distribution, with a large number of coarse particles (about 92% above 1 mm) and nearly 34% ultrafine (size <125 um).

Because traditional casting features grain separation at the contour, it requires further machining, which raises production costs [17].
PM avoids problems associated with the traditional smelting process, in addition to controlling the growth of the grain [21].
The trend analysis showed that there has been a growth in the number of publications, especially reflected in the last year; however, these publications were distributed in a wide range of journals.
