There will be some weakening effect, but with the increase of the distance to the excitation coil, the magnetic field within the gap will be quickly attenuated, so such a reduction is small.
The main equipment includes the servo load testing machine, data acquisition, and a DC power supply.
This performance Test is mainly on the following two aspects: on the one hand, studying the relationship between damping force and displacement, velocity; the other hand, basing on the test data, assessing the variation of damping force and damping coefficient with current (magnetic field), amplitude and frequency.

This study would provide a useful data for discussing liner system stability. 　 　
Model Dimensions and Boundary Conditions Combined with the basic practical engineering data, the finite element model of landfill liner system was established by ABAQUS (See Fig. 2).
At the same time, due to the decreasing thickness of MSW, the shear stress of the right end slope also shows a decreasing trend with the reduction of interface normal stress.

Also plotted on this figure are experimental data points for Si superjunction-MOSFETs and recent 4H-SiC MOSFET results.
There is a reduction in the drain current at the elevated temperature due to an increase in the drift, JFET and substrate resistance, a result of lower bulk mobility at higher temperatures.
The decrease in VTH at low currents (sub-threshold region) results in a slight increase in leakage current at VGS=0V compared to pre-BTS IDS-VGS data [3-4].

It must be noted here that the major benefits that are achieved due to application of integrated engineering systems are the following: possibility to develop dedicated software routines on the basis of already defined parametrical models (the F-16 aircraft); elimination of inconvenient improvements to the geometrical features that extend the time necessary to develop a geometrical model during the initial phases of the engineering process (the EM-11 ‘Orka’ aircraft), reduction in the number of variables used for process of the model parameterization (the steering system of the MiG-29 aircraft), definition of rules for functional relationship of indirect parameters involved in the engineering process (the EM-10 ‘Bielik’ and the EM-11 ‘Orka’ aircrafts [16, 17, 18]).

Temperature data during full bone drilling without back rotation (2mm/s; drill bit Ø4 mm). .

The method is to fix an photoelectric encoder on rear reduction gear.
When identifying black lines, the first six data of each line corresponds to useless video signals.
Therefore, judgestarting from the sixth data.

Image processing is considered as an attractive and flexible technique for automatic analysis of road traffic scenes for the measurement and data collection of road traffic parameters [1-5].
To reduce the amount of data and to eliminate the effects of minor motion of the camera, single-frame analysis has been considered in this system.
A typical classification problem involves the steps of feature extraction, feature decorrelation and reduction, clustering and segmentation.

In order to reduce computational effort, model reduction techniques are applied.
Whilst an (bi-) orthogonal transform has been shown to be important for applications such as data compression and fast calculations, such importance has not been shown for multi-resolution analysis. [4] The use of the continuous wavelet transform has gained increasing importance in many fields in analyzing the texture of matter distributions.
In solving partial differential equations, the primary challenge is to create an equation that approximates the equation to be studied, but is numerically stable, meaning that errors in the input data and intermediate calculations do not accumulate and cause the resulting output to be meaningless .
