Pole figures were constructed from the X-Ray
diffraction data.
During the test, data of load-displacement-time were stored in the computer memory at frequencies appropriate to the strain rate range.
The stress-strain curves of RD and TD samples are shown in Figs. 4a and b, the SRS data is shown in Figs. 4c and d, and the r-data are given in Figs. 4e and f.
It can be seen that the data can be well fitted by straight lines of decreasing slopes.
Additionally, the data also show correlation in the comparison between RD and TD samples.

July and August MAP data show that source water MAP content is higher, generally higher than 10 μgPO43--P/L, in August source water MAP of 38.21 μg PO43- - P/L up even (this rate is higher than the MAP detection method of the upper limit 10 μg PO43- -P/L, this MAP data using MAP yield coefficient calculation).
From the current MAP data source water, it is difficult to see the MAP and seasonal change whether there are laws.
July filter effluent water than J waterworks MAP of a 34% reduction in August, the filter water than J waterworks water dropped 83.7% MAP.
So it is difficult to draw the conclusion about the issue over the limitation of phosphorus from the data in February and can be further analyzed in trials experimented in July and August.
From the above data we can see, AOC concentration mostly over biological stability control concentration (AOC < 100µg acetate - C/L ).

So engineers try their bests to reduce hard disc access, instead to read data from high speed memory.
When the number of application system is increasing, the amount of data is increasing exponentially.

The model is validated using data of three engines.
The testing data collected cover duration of 800 seconds.
The exhaust temperature data are shown in the 1st plot of Fig. 5.
In Fig. 5, the experimental data and prediction data of exhaust temperature are shown in the 1st and 2nd plots.
The relevance is strongly and qualitatively supported by data matching.

For this reason, researchers
are switching from mechanics-based models to data-driven approaches [2,3].
Data-driven models renounce to provide a detailed description of the mechanics of the structure.
The correlation laws were estimated on the basis of a limited set of experimental data on RC columns.
For this reason, data-driven approaches are becoming more and more frequent in such kind of simulations.
Development and validation of new bouc-wen data-driven hysteresis model for masonry infilled rc frames.

Main coastal wetlands were in Tianjin Binhai New Area, for better analysis, statistics data collection were limited in this area (Fig.1 c).
In addition, economic and demographic data for the period 1993 to 2009 were from the Yearbook of Tianjin[12].
According to monitoring data, the water quality of surface water bodies of Tianjin city was exceeded Chinese national class V.
The data showed that reclamation area increase quickly from 2004 and the natural shoreline remain 68.49km in 2010.
In fact, because of the lack of history data, the method which space instead time was be used in succession study[13].

This shift is defined as the difference between (002) peak position of ZnO (determined from JCPDS data card (36-1451)) and (002) peak position of the film (determined from XRD data).
The observed dhkl and c values are in good agreement with the standard values taken from the JCPDS data card (36-1451) [28].
This result is in agreement with XRD analysis data that reveals an increase in degree of crystallinity of the films.

Bagga et al. [16] created a matching between predicting data of tool wear and manual measurement data.
The data is processed in the hidden layer mathematically, then transferred to the output layer with final weight.
To implement ANN, Weka (a type of data mining software written in java language) was used.
This research focuses on classify tab; which provides several machine learning algorithms for the classification data.
Besides, a percentage split of 70% was used to divide data into two groups: 70% of data was used for training (56 samples) and 34% of data used for testing (24 samples).

Aiming at the phenomenon of generator air gap magnetic potential asymmetry and effective fundamental magnetic reduction after the fault, paper [7] has calculated the unbalanced magnetic pull force by rotor winding inter-turn short circuit fault.
In order to accurately calculate the unbalanced electromagnetic force by the rotor winding inter-turn short circuit fault, this paper proposes to analyze generator magnetic field by finite element method, and magnetic field data before and after failure is got by accurate calculation, and further the unbalanced electromagnetic force is calculated.
By calculation, the magnetic field data in no-load state is obtained, which can be used to further calculate the radial magnetic force of the rotor outer surface, seeing in equation (2) [13-14]
After modeling and loading, the nonlinear Poisson equations and boundary conditions are used for solution, then generator magnetic field data are got.
Conclusion This article compares the analytical and mathematical calculating methods for turbine generator unbalanced electromagnetic force by rotor winding inter-turn short circuit fault, proposes to use the numerical method for unbalanced electromagnetic force calculation, generator magnetic field variation are analyzed after rotor winding inter-turn short circuit fault, magnetic field data are obtained to calculate the distributed electromagnetic force, the final results show that the numerical simulation can more accurately express the electromagnetic force state that generator rotor suffered, which provides the basis for further composite force analysis.
