In order to avoid the orientation noise, misorientations below 2° were not considered in the data post processing procedure.
Three different stages of the recrystallisation are clearly distinguishable after examination of the hardness tests results shown in Fig. 1b, together with the evolution of the microstructure and microtexture during annealing represented by the OIM data, (cf.
Fig. 4: φ2=45° section of the ODF for the following samples: (a) hot band material, after (b) 10%, (c) 35% and (d) 70% reduction, after annealing at 800°C for 4 hours following (e) 10 %, (f) 35%, (g) 70% of reduction and after annealing at 900°C for 4 hours following (h) 10 %, (i) 35%, (j) 70% of reduction.
After a reduction of 10%, the samples annealed at 800°C for 4 hours displayed an average grain size of ~130 µm, ~50 µm for 35% of reduction and ~30 µm after a reduction of 70%, (see also Fig. 2g and 2j).
Shear bands with 20 to 35° of inclination with respect to the rolling direction are formed at reductions of 35%.

The current data was used to calculate the power and total electrical energy consumption for the injection molding using Equation 1 & 2 respectively.
This data was then used to generate a suitable energy map which will be discussed in the results and discussion section.
Simulating the amount electrical energy reduction by having to undergo 1000 shots using these particular machine results in reduction of 3.1 % or 51 kWh (shown in Fig 6).
The reduction only refers to one machine in one same operation.
Any reduction of carbon emission supports the sustainable development.

Surprisingly, there is a general lack of data in the literature concerning the influence of grain size on area reduction in monophase ferritic steels, particularly in the submicron domain.
In order to compare the ductility of monophase ferritic steels with sub-micron grain size, the uniform elongation and the area reduction are drawn as a function of the carbon content (internal data for carbon content lower than 0.3wt% and data from [2] for higher content).
Variation of the uniform elongation, the area reduction at fracture and the ultimate tensile strength with the carbon content for as quenched martensite (internal data for carbon content lower than 0.3wt% and data from [2] for higher content). 3.
Evolution of the uniform elongation, the area reduction at fracture and the ultimate tensile strength with the tempering time at 150°C for 0.4%C martensite (data from [2]. 3.2.
A general lack of data on the area reduction as a function of the grain size in the monophase ferritic steels, especially in submicron range, has been noticed.

SAR data are widely used for the treatment of SAR images, so that become one of the SAR image change detection sensing current cutting-edge technology development.
Change detection based on S3VM Initialization Standard SVM training set using samples of the pseudo-training data find an optimal separation hyperplane, and make it the largest margin on both sides of the interval[3].

This paper deals with the reduction of residual stress induced during the selective laser melting with a mixture of ferrous based metal powder.
This paper deals with the reduction of residual stress induced during the layered manufacturing processes.
The laser beam then was irradiated to the powdered surface through a galvanometer mirror, and scanned on it with programmed NC data.
Reduction of residual stress To investigate the influence of heat treatment to the beam model on the reduction of residual stress within the consolidated structure, the effect of preheating and post heating of the beam model was examined.
The preheating was performed to the base plate surface to investigate the reduction of residual stress on the base plate.

Then, a linear two-step reduction technique is used to reduce the high-order process to a second-order plus time delay model based on the frequency response data.
In 1995, Wang and Cluett[7] provided an identification method to deal with noisy step response data by using the Laguerre series expansions.
Then an SOPDT model is obtained based on a simple model reduction technique in frequency domain.
Here, a simple model reduction technique based on the frequency response is used.

During recent years, the Taiwan government launches issues of green building , sustainable engineering , carbon reduction and etc. , to promote balance construction and environment ecology.
According to the data from X-ray diffraction and chemical analysis, it can prove that the chemical elements including SiO2, K, S, Ca, Mg2 and other chemical elements in RHA will have different ratio by different temperature of burning ash [6].
The following contents will analyze and discuss the benefit of cement strength efficiency, economic and carbon dioxide reduction.
Table 2 shows the 20% replacement of cement with RHA, the reduction of CO2 and the result of environmental protection.

Introduction Gene selection is an important aim of a microarray data analysis, as it can reveal information leading to a better understanding of the mechanisms of the investigated phenomenon.
Ke et al. [3] introduced a new approach based on ACO for the purpose of attribute reduction.
In Section 3, the experiment results on various public data sets are discussed.
The data sets include leukemia data set, colon data set, breast cancer data set, lung carcinoma dataset and brain cancer data set.

Reference [1] focused on the numerical simulation of nine roller H-straightening, on the occasion that only one of the roller reductions changes, the other three rollers do not change, then it discussed the impact to residual stress of straightened rail caused by the reduction.
FEM Model Foundation of Rail Straightening Through the data of certain factory, the limited value of original bending curvature radius is 63m.
Experimental Plan Design In rail actual compound straightening process, the reductions of 2#, 4#, 6# and 8# roller in the H-straightener can be adjusted, the reduction of 11#, 13#, 15# and 17# roller in the V-straightener can also be adjusted.
In the on-site actual straightening regulation, 17# roller in the V-straightener does not roll down, the reduction value is 0mm, the active reduction value of 2#,4#,6#,8#,11#,13# and 15# roller are respectively 19.2mm,11.2mm,7.9mm,3.5mm,12.0mm,6.0mm and 2.5mm.
