Several long-term meteorological data sets were used in this study.
The stations with missing data of more than one year will be excluded from the dataset and the daily data at 51 stations are analyzed in this study.
In some cases data was limited prior to 1970s, in which instances the means are more heavily influenced by data from those stations with the longest periods of record, i.e., Urumqi.
We first compared it with observed climatology of precipitation data set on yearly basis (Fig.2).
As the trend in both observed and simulated data are in the same direction allowing use of simulated daily data for future analysis of extremes indices.

A good qualitative agreement between the calculated and the experimental data was reported.
The obtained results were compared with corresponding data for an ultra low carbon steel (ULC) sample representing one phase steel.
The calculation of the texture index IDN for the data simulated by the LAMEL and FC Taylor model data resulted in a values 0,29 and 1.39 respectively.
Here again the LAMEL model gives results being closer to the experimental data.
The results presented above showed that the FC Taylor model calculations give large discrepancy with respect to the measured data.

The paper presents data on the temperature dependence of the conductivity of strontium bismuthate Sr6Bi2O11.
Interpolating the experimental data with a semicircle, we can find the point of its intersection with the line Z`` = 0.
Nyquist plots for strontium bismuthate Sr6Bi2O11 at different temperatures Fig. 2 shows data for only 4 temperatures.
The graphically obtained experimental data are shown in Fig. 3.
The obtained data can be interpreted as follows.

Establishing Open data set and unified framework standard are two main Problems and further research directions.
Then, an algorithm, which extracts high-quality feature extension modes from training data, is designed.
In the second stage, we enrich questions by leveraging Wikipedia semantic knowledge to tackle the data sparseness.
Open Data Set.
Although experiments show the classification results of above methods in 3 are very good on their specific background and data set, there are few open data sets for different short text classification testing and comparing.

From the data of FAA/NASA, over the past 18 years, tailplane icing has been responsible or at least suspected for 16 accidents with 139 fatalities [1].
This program included the wind tunnel tests of the tailplane [5-6] and flight tests [7], which provided much data for the study of the tailplane icing.
is the test data vector with dimension of m.
According to the flight test data of clean aircraft provided by the Fig.C-1 in Ref. [7], the aerodynamic parameters of the clean aircraft are identified.

The infrared transmission module uses RS-232 serial-to-infrared technology to realize wireless data delivery.
Furthermore, the data can be transmitted and processed automatically.
Its main functions include system configuration, system control, data storage and data display.
X25043 also has a 512×8-bit serial E2PROM, which concurrently can be a data memory (RAM) without additional extension.
As the data transmission of the slave is conducted online, the built-in storage unit within AT892051 can be used as the data storage unit.

Introduction Reverse engineering fields have been developing to get better 3D shape data by increasing the speed of the data acquisition and improving the geometrical accuracy of the data from the object.
To acquire 3D data from the object, both passive type and active type scanners are used.
To receive good quality 3D shape data from the object, each axis must be properly aligned (Fig. 3) [2].
This effort will result in better quality 3D data and improved accuracy of the hardware [4].
From this information, spherical coordinate data can be acquired and properly analyzed [3].
