We present resonant x-ray scattering experimental data from YVO3.
Furthermore, it is suggested that through this transition there is a brief reduction of the crystal symmetry, resulting in a complete loss of intensity in the (010) ATS reflection.

Therefore, on the premise of reserving data detail and contour information for model reconstruction, simplify the measuring point cloud data is very necessary.
Fast neighbor searching requires a good data structure to avoid searching the entire data set for each candidate point.
First, the min-max box of the data set is computed.
But there still exists redundant data at the lower edge of the model.
Nonuniform simplification of cloud data based on octree.

.% are used as working fluid and then compared with the data for water-cooled heat sink.
For pressure drop, the data show that the pressure drop of nanofluids is a few percent larger than that of the water-cooled heat sink.
Calibrations of all instruments are done for estimating the accuracy and reliability of the measured data.
The data indicated that the heat transfer performance increases as the particle concentration and Reynolds number increased.
This is due to small amount of nanoparticle dispersed in the base liquid had insignificant effect on the pressure drop data.

WPIMS could provide the wind turbine mechanical vibration data, wind speed and temperature status of the data, the output voltage and current data, and post-vibration, post-wind speed and post-temperature data into the fact base, and with the combination of expert inferencing rules, the expert information that matched the requirements would be provided to inspect user.
Figure 1 Block diagram of fault diagnosis software The fact data acquisition subsystem.
The the main function of fact data acquisition subsystem is to provide derived data that the inspect user can not provide but of importance no expert knowledge, which are vibration data, wind speed, temperature, real-time voltage and current data.
After unified treatment into vector data by WPIMS, these data were saved to MySQL database, to be corresponding analyzed and processed.
For eaxmple the vibration data is mainly used to analyze the kurtosis index and crooked index data. hourly mean wind speeds every day were used to calcuate mean wind speed during the period of each work and so on.

Data evaluation approaches.
(b) Xj values are estimated by successive data reduction or decomposition steps on the basis of Yi,obs.
(b) Detail of observed data from (a) together with LaB6 data representing instrumental resolution (scaled, straight line). 3 Data evaluation procedures 3.1 Basics of data evaluation: Procedures A-C Data evaluation was performed using the TOPAS suite of programs [16] by minimising the difference between observed and calculated profiles.
Furthermore, the calculated evolutions of κ2(∆εhkl) according to Eq. 18a (data from procedure B) and Eq. 20 ( = 2; data from procedure C) are shown.
The corresponding curve calculated from procedure A by further data reduction of the extracted individual reflection parameters is virtually indistinguishable from the present one and is, therefore, not shown.

According to the preliminary research data optical compound used to fabricate lenses does not change its optical properties in the whole range of used fast neutron fluencies.
Research data obtained under radiation exposure in passive powering mode, i.e. without operational current, were used for making the LED radiation model.

IRT can be defined as the science of acquisition and analysis of data from noncontact thermal imaging devices [8].
Results The analysis of the two white paints (C_White and R_White) was performed during one day (8th February 2013) using thermocouples and thermographic data observed on the South façade of one test cell.
Percentage differences between data obtained with the two methods, for R_White and C_White paints, are also presented in Table 2.
Additional data show that the two white paints had different thermal performance (for the specific studied day - 8th February) between about 9h30 and 17h30, corresponding to approximately insolated facade time.
Small differences (5%) between IRT and thermocouples temperature data show the good accuracy of IRT method for setting temperature distribution of surface façades.

For testing materials, torsion pendulum has standard requirements for size of test specimen, clamping manner and clamping force, which facilitates error analysis of data.
Damping data obtained through the test will be more accurate through error analysis and range of temperature for use can be from liquid nitrogen temperature to 1500oC.
This scheme can basically meet requirements of the non-linear damping test of magnesium alloys and the test data obtained on the relationship between damping and strain of the AZ61D magnesium alloys can reflect damping capacity of the magnesium alloys.
The basic principle of the damping test device and damping and strain test data are shown in figure 7 and figure 8 below.
Besides, the test data can reflect comprehensively the damping capacity and advantages of magnesium alloys making them the best alternative scheme for testing damping capacity of magnesium alloys.

The linking between C# and MATLAB is done using COM automation server and the data in the client C# program passes it to MATLAB and vice versa.
The Interface Free Controller Cards (IFC) is a set of IFC controllers used in the project to exchange the sensing and actuating data.
The brush motor card (IFC-BH02) is a slave card and it is used to supply power and getting data from encoder.
The DIP input data is coming from IFC-BL02.
IFC cards were used as the embedded controller to transfer and receive the data between the electronic and mechanical parts of the platform.

We were using the database of operational observations in the L1 sector for the period of 300 days – 5,461 data, L2 sector for the period of 2,710 days – 20,953 data, and L3 and L4 sectors for the period of 2,579 days – 21,284 and 25,718 data, accordingly.
Therefore, it was necessary to separate the relevant data from the other data, which was carried out applying the line counting technique.
Subsequently, the obtained data were processed using computers in the Microsoft Excel - basic data analysis, and the Statistica software – multicriteria comparison of failure rate similarities between individual sectors.
They belong to the methods of explorative analysis of multidimensional statistical data.
Such normalised data can be subsequently used as the input data for the Statistica software.
