The use of welding is very extensive in today’s technology for the benefits like weld strength, freedom in design, joining of metals and their alloys by means of both similar and dissimilar and possibilities of joining of workpieces through spot, seam and in a number of other configurations.
Taguchi design of experiment employs various experimental approaches by taking the number of process parameters and the output results for the optimization of process parameters.
Due to much less heat input, grains of the stir zone (SZ) of the FSW joint are finer than those of the MIG joint, resulting into higher hardness [8].
The more attention gives to recrystallization mechanism, grain boundary characteristics, phase transformation, texture evolution, characteristic microstructures, and the effect of these factors on the hardness, tensile and fatigue properties as well as superplastic behavior of FSW/FSP aluminum alloys [13].
The degrees of freedom of the model are the number of process parameters taken for the fitting of the regression model with the responses.

Considering in detail the main business processes of real production, it can be noted that in the field of organization of food production, the number of providing process include various processes of product quality control, the use of various technologies, as well as processes related to the processing of information and decisions.
As can be seen from the figure, the level of the error of distinction (the number of incorrect solutions per 100 implementations of interference) of the reference spectra depends nonlinearly on the value of the noise/signal ratio H0.
The reason for the random nature of the experimental data is that they are formed under the influence of a sufficiently large number of simultaneously acting factors.

These elements in different thermal deformation process can make the steel to achieve good match between strength and toughness by the precipitation hardening and fine grain strengthening.

Introduction Poly(vinylidene fluoride) (PVDF) of Industrial products exist as the form of spherulites,and there are a large number of holes among spherulites, very conducive to surface modification, then obtain functional polymer matrix material.
In addition，grain size increases with film thickness, crystal accumulation of particles is loose, less dense membrane; Non-polarαmonoclinic crystal particles formation in high temperature, close contact between the particles and the film density is excellent.

Diffusion of both aluminum and oxygen at the grain boundaries led to formation of new Al2O3 within the oxide layer.
In the diffusion zone,Fe diffused outwards from the substrate to the coating while Co diffused inwards from the coating to the substrate.One reason for this may be that Co forms substitution solid solution with Fe,which means that Co has high solution in the Fe base due to the fact that Co atomic number approaches that of Fe and their atomic radius difference is very small[10].Moreover, Ni diffused inwards from the coating to the substrate slightly in comparison with Co while Cr hardly took part in the diffusion 10μm obviously and mainly distributed in the coating.

It’s assumed gray black, thin of grain, slide of handle and had some hardness of water.

The characterization of organic compounds present in material, sponge and powder calcinated has been checked by Fourier Transformed IR spectra using a FTIR Spectrophotometer in the wave number range of 4000 cm-1 to 400 cm-1, in transmittance mode.

Although most lack the fine grain discrimination required for the retrieval task, the retrieval performance can be greatly improved by the combination of descriptors or some novel descriptors [7, 8].
Precision-recall plot: For each query model in class C and any number K of top matches, Recall is the percentage of models in class C accurately retrieved within the top K matches.
