In the meantime, the curves imply that the lower the Ip, the greater the reduction of OCR.
The two methods are empirical based on a large number of measured data.
The test data of the foundation engineering project show small discrete and the evaluation of over consolidation state can be reflected by mean value of OCR.

The tests have been performed on universal testing machine TiraTEST 2300 with an automatic extensometers to measure both, the specimen’s longitudinal elongation and transversal reduction.
The section data of the major and minor strains was displayed and subsequently exported into the three separated files for each specimen.
The limit major and minor strains for each section of the specimen have been calculated according to EN ISO 12004-2 [6] when section data have been imported into the FLC mode of the Argus software – Fig 4.

The identity of RAECs was confirmed at the first passage with the use of goat anti-rat Factor VIII (a stable endothelial antigen) and goat anti-rat α -actin antibody and the FITC conjugated rabbit anti-goat IgG (data not shown).
Total nitrite was quantified after the reduction of all nitrates with nitrate reductase (Sigma Aldrich).
Statistical analysis All data were expressed as means ± S.E.M.

And, n’ and k’ can be obtained by experimental data.
Therefore, it will have the effect of drag reduction when VES fracturing fluid is added in the pure CO2.
Calculation correlations between frictional resistance coefficient and Reynolds number can be obtained by the experimental data: (9) Average correlation coefficient of the calculation correlation is 0.999,and average error is 0.15%.

Experimental modal analysis technique is used to obtain the system input (excitation), the system dynamic parameters or the system output (response) data by the vibration sensor, signal acquisition, analysis equipment and computers.
Then the signal was input to net data acquisition instrument WS-5921.
When the FVF of laminated composites is less, the damping is larger, the performance of amplitude reduction, vibration absorption, and energy dissipation are all better.

In the formula:——The temperature of experiment;——The reduction factor of temperature.Copper winding =234.5.Aluminum windings = 228.
The analysis of experimental results.It is concluded that different loss of the motor fed with variable frequency power in this paper The experimental data as shown in table 2.
Summary Through analyzing the characteristics of asynchronous motor in frequency conversion power supply in this article, the simulation result of the rotor stator copper loss and iron consumption is smaller than standard for less than 8%;the measured stator copper loss and rotor iron consumption is bigger than standard respectively by 13.63% and 9.95%.The data illustrate that the iron loss of motor frequency conversion power supply is bigger than the power frequency power supply.

This algorithm compensates the G component of raw data with the local windows of Bayer format.
Algorithm I proposes to remove the crosstalk using the following formula: (1) Algorithm II suggests to remove the crosstalk using the following formula: For the Fig 2(a): (2) (3) (4) For the Fig 2(b): (5) (6) (7) Algorithm III proposes an adaptive edge-preserving filter to remove the effect of crosstalk with the following formula: (8) (9) (10) (11) (12) (13) (14) Algorithm IV compensates the G component of raw data with the adjacent R or B components before interpolation.
The AL/HP algorithm are proposed to simultaneously estimate low/high frequency image and provide adaptive threshold based on the human visual characteristics for crosstalk reduction.
