Once the diffusional process is carried out, the material is assigned transformation temperatures at each integration point in the matrix using a fit of data given in the paper of Frenzel et al. which relates transformation temperatures with concentration of pure unprecipitated NiTi material.
Reduction in transformation strain, smoothening of hysteresis, reduction of stress necessary for initiation, and change in hysteresis width are all visible.
The analysis has shown many characteristics of precipitation reflective of experimental data, namely a decrease in maximum transformation strain, shift of transformation temperatures to higher values, increase in difference between start and finish temperatures, and smoothening of response hysteresis into a gradual transition between phases.
These characteristics all are magnified with an increase in the amount of precipitation and reflective of results seen in experimental data.

Multifunction sensors application allows to provide effective measurements due to the following factors:
• use of one sensor instead of several ones;
• reduction of the equipment quantity and inserts points in process that allows to meet strict requirements for environmental protection easier;
• expenses decreasing at design, installation and maintenance;
• time reduction for measurement results processing;
• correlation dependences application for increase of accuracy and reliability of information.

The measured data was recorded with a PC-based, fully automated data acquisition and data logging system.
During the first few minutes of bearing operation at 1 kN load (Figure 4) a significant reduction of the frictional torque was observed, indicating that the bearing top foil underwent a wear-in process.
Similar reduction in frictional torque was observed in most experimental runs, and although it was not as significant as during the initial run with new top foils (Figure 4), it suggests further wear-in of the top foil during testing.
This significant reduction of the friction coefficient was the result of a closer to optimal film thickness, which allowed for higher developed hydrodynamic pressure and higher load capacity.

The reduction coefficients are chosen subjectively.
But the use of the traditional in-site experiment is limited because the data of rock mass mechanical parameter is discrete and multi-scale characteristic.
Attenuation coefficient is computed by fitting data method. (4) Substituting attenuation coefficient and the first characteristic frequency and rock elastic modulus into Eq. 13, then viscosity coefficient is derived.
The attenuation coefficient is calculated by data fitting method; (5) substituting attenuation coefficient of five gauging points and the first characteristic frequency and viscosity coefficient of rock into Eq. 13, then equivalent elastic modulus is obtained.
So strength reduction coefficient of rock mass can be determined according to equivalent elastic modulus.

In contrast, AFM give major advantages because it is quicker and does not required a specific sample preparationbut yields data that are at least straightforward and easy to analysis [10].
The 20, 30 and 40 nm of AuNPs was synthesized using the citrate reduction method.
The number of data point present in the x and y scan direction on image needs to be taken into consideration during image analysis.
Prior analysis, the first step in AFM image processing is all imaged need to be go through flattening technique using a polynomial fit by fitting each scan line and subtracting it from the data to remove the artifact from the image acquisition process [14].
However, the measurement by AFM was relatively straightforward, ease in sample preparation and interpretation of data compared to TEM analysis.

Between motor and roll, a planet cycloidal needle wheel decelerator is stringed to obtain the reduction ratio as 15:1.
When controlling three motors in this paper, multiple background data block is used to reduce the number of data blocks , as shown in Fig.2. where, FB10 is called in the OB1, then FB1 is called(by eace motor) in FB10 to control three-motor system.
All the data of FB1 is stored in its background data block DB1 for each calling.
Data sampling includs collecting the data of speed and the tension response, recording speed and regulation of tension that PID controller output to the inverter in corresponding time.
Given different data section of the input, then the static characteristics is measured from output response.

The idea of CV is closely related to model reduction of parametrized partial differential
equations, which consitutes nowadays a very active field of research in applied mathematics and
engineering.
This is achieved using a model order reduction technique, the Proper Generalized Decomposition (PGD).
