These studies of test the experimental data are scarce, with most model tests is still small-scale.
The data acquisition used INV306 which is developed by Oriental Vibration and Noise Technology Institute.
In the center of the third layer floor input the power dynamic load waveform data then picked up by channel 6.
We compared sensor collecting data of the sixth steel frame floor on soil tank.
In this paper, the structure added natural period, the stiffness of the structure, the structure in the peak acceleration reduction means and the rigidity fitting data of structure was established for the model, if the actual structure was used the data to calculate the soil structure interaction it should conside the size factor.

The following data was taken as the optimization parameters: y1 – process specific output, [t/(m2h)]; y2, y3 – impact resistance(x) and friction resistance (x1).
To a certain degree it was confirmed by the experiment data when the layer height was increased to 700 mm, the fuel consumption comprised 4.8 % and vacuum under the furnace grate was not enough and equaled only 5 kPa instead of 6 kPа.
Thus according to the sieving data the agglomerate after dropping contained 14.2 % of 5 – 0 mm fines and x and x1values equaled 75 and 5 %, correspondingly, at the sintered layer height of 500 mm.
This is also confirmed by the filtration rate data.
Higher strength of the agglomerate produced at comparative fine ore sintering is evidenced by test data as per GOST 15137-77.

The ferromagnetic garnet has been popularly used in very high frequency (microwave), telecommunication and data storage applications due to their interesting magnetic and magneto-optic properties [2,3] and also widely used in electronic devices as isolators, circulators, transmitter, and transducers of acoustic energy [4,5].
The temperature reduction and percentage hydrogen consumed are presented in Table 2.

Too broad width is negative for the road noise reduction and smoothness improvement.
Therefore, in the limited technical conditions and economic situation, equidistant groove is recommended. ②The greater the equal spacing, SFC and TD are smaller, the anti-sidle and drainage performance is worse, noise reduction effect is better. ③The greatest impact on the noise reduction is groove trend, followed by groove spacing.
The influence of groove form, groove depth and groove width on noise reduction is very small.
It corresponds with too groove width having negative effect on noise reduction and smoothness, so the6mm groove width is abandoned.
The flexural strength of no groove specimen is 6.13Mpa, the average compressive strength is 1050.1KN, and they are significantly greater than the data of groove specimens.

The estimates of global wave-generated electricity supply potentials were allocated to the 48 energy production and consumption regions and classified into five cost categories based on data provided by [1,11-13].
Table 1 shows the input data for selected important electricity generation technologies other than non-biomass renewables, while Table 2 shows the global technical potential of seven non-biomass renewable electricity technologies at different cost categories.
The input data for CCS are given in [9,15].

In order to further understand the Agave americana var. marginata electrical signals in High Voltage Pulse Stimulation conditions, a new method is provided in this paper by using wavelet soft threshold noise reduction and the power spectrum analysis.
The laboratory temperature 29-30 ℃, humidity 62% -65% RH, the sampling frequency is 20Hz, the low-pass filter frequency 5Hz, measured data points is 4096.db7 with 7 layers of wavelet decomposition of the signal, the noise is calculated based on the signal strength, draw global threshold, then apply the global soft threshold for signal noise reduction.
After the noise reduction signal, estimate the power spectrum and analyze the variation of plants at different voltage electrical stimulation.
Conclusions Wavelet soft threshold noise reduction for inclusion in the plant electrical signal has played an important role in well eliminates noise and power spectrum analysis can clearly understand the plant electrical signal frequency components.

It has been found out that the coating increases the antifriction properties of ceramics both due to lower coefficient of friction of the coating material and to reduction of roughness of rake face of the tool, and that is the main cause of 25% reduction in cutting force components for the coated tool, wherein the difference in cutting forces for the coated and uncoated tools is inversely proportional to the thickness of the slice.
The analysis of the data obtained suggests the following.
It is clear that the reduction of tool surface roughness can favourably affect the improvement of the surface friction properties and, consequently, improve contact processes occurring in the cutting zone.

The design process starts from receive the requirement data, elaborate the data to the design specification.
Literature Reviews The problem of minimum volume preliminary design of simple and multiple-stage spur gear reduction units has been a subject of considerable interest, since many high-performance power transmission applications require low weight.
Another gear data were according to the standard of gear design.

Incorrect cooling, however, can lead to heat unbalance in the die casting tool, thus causing the destruction of casting quality, reduction of the lifetime of die casting tool and irreversible production-reduction.
Thermal data is given in tables.
For each calculation only 1 parameter was changed, for the others general workshop data were applied. 2.
Given and calculated data are presented in table 4.
In production these are the most varying parameters and this is why it is justified to continuously monitor them with data collection systems [5-6]. 4.

A Computational Approach for the Assessment of Seismic Vulnerability based on the National Data Infrastructure Gabriela M.
The algorithm considers all the possible tests that can split the data set and selects a test that gives the best information gain.
In order to gather the entropy gain of all these binary tests efficiently, the training data set belonging to the node in consideration is sorted for the values of the continuous attribute and the entropy gains of the binary cut based on each distinct values are calculated in one scan of the sorted data.
These data correlated with data on the real earthquake accelorograms identified from the national seismic database have the basics for the decision tree induction algorithm.
