The laser nitrided has showed an improved creep behavior compared with the same alloy with N-PIII coating, with a reduction in the creep rate and increasing the creep lifetime.

Data Analysis
The scatter band for a material grade is generated by assembling the mean curves of the single melts.
The training data comprised about 400 single tests on specimens from 25 different melts (only CC, no HIP).
Fig. 1 displays isothermal curves for three specific melts together with belonging data points.
The verification of a neural net model is favourably executed by testing the ability to reproduce the relation between input and output data for a data set, which is completely different from the training data set.
Master-curve for the data in Fig. 10, based on Manson-Haferd-Parameter PMH. 4.

Empirical result
In order to test the accuracy of algorithm, we use MovieLens as benchmark data sets.
The data set 1 consists of 105 ratings for 1682 movies by 943 users, the data set 2 consists of approximately 106 ratings for 3952 movies by 6040 users.
We divided each data set into two parts based on rating time, which can be distinguished by the timestamp of the movieLens data.
Typically, as for the two different data sets, we selected 30% records for each user that occurred in recent time as testing data, others 70% as training data.
Acknowledgement We acknowledge GroupLens Group for providing us the data set MovieLens.

For questionnaire survey, the exploratory research method was used for the study, which involved quantitative data gathering stage.
Data reduction of each item in the indicator by using Varimax Rotation Method Reliability 1.
The combination of PCA method and Varimax Rotation Method with KMO test was used for data reduction of all variable under each indicator.
Besides that, the data reduction of the variable which below the required limit gives a higher accumulated variance value (%) which is 58.581 – 69.419.
The analysis of the qualitative data from SPSS instrument identifies five indicators that satisfy the quality measure limit.

Experimental household, experiment design, and the methodology for securing data
Sampling household.
Relate data availability.
For the data of swine rearing and sub-productivity, we opted for four roughly same sized piglets that had been born by three way cross hybridization.
For sub-productivity, its data leaned on the equation:
Feces and urine quantity came at 180d/396kg and 190d/522 kg, pursuant to experimental results, and other data in connection with energy were determined on the methodology proposed by Luo(2000) [8].

In order to determine the airtightness performance of dilapidated dwelling according to built year, the collected data was divided by 10 years according to built year and it was classified from 1960s to 2000s and the average ACH50 was calculated (Fig. 8).
In order to determine the airtightness performance status of dilapidated dwellings according to the type of window, the collected data was classified according the type of window and the average ACH50 was calculated.
In order to determine the airtightness performance status of dilapidated dwellings according to the material of window frame, the collected data was classified into PVC, wood and aluminum according to the material of window frame and the average was calculated (Fig. 10).
The data collected through this study was the analysis data from 27 dwellings and it is difficult to generalize this data as the status of all dilapidated dwellings.
Therefore, a follow-up study to improve the reliability by collecting data through more actual measurements should be carried out in future.

The constitutive equation and dynamic recrystallization kinetics motel are set up through analyzing and calculating the data of thermo-simulation.
The deformation temperatures range from 870℃ to 990℃, strain rate range are 0.001s-1 , 0.1s-1 and 10s-1 respectively, and the single reduction ratio is 60%.
These models can be rewritten, after taking the natural logarithm of both sides as: (4) (5) (6) Inserting the experiment data of the peak stress and the strain rate measured at different temperature into the above formula, the relationship between strain rate and peak stress is shown in figure 2.
The recrystallization critical strain can be obtained by measuring the peak strain: (13) According to the stress-strain curve based on experimental data, dynamic recrystallization volume fraction can be determined

Statistical Analysis
The collected data were analyzed using SPSS version 22 software.
Data exhibited on the curves were stated as mean ± SEM, and other data were stated as mean ± SD. 3.
This information confirms the results of the MTT assay data, but there were differences in their patterns.
In addition, the data for 72 h are shown in Fig 4(c).
The nano-sonosentization data demonstrated that human cervical cancer cells were sonosensitized by GNPs.

Another source for fatigue data on this type of material
is form the FAT [5] project.
The data of the statically tested materials from Wagener's [5] tests deviates from the test data from the more recent tests.
The cyclic test data differs strongly from the data of previously tested TRIP700.
The data available was created in the same way as the current data.
The FAT [5] data is for three amounts of prestretch, 0%, 10% and 17%.
