The introduction of the anti-bending dampers is seen as a significant reduction in the bending vibration of the carbody.
More concepts regarding the reduction of the carbody structural vibrations and enhancement of the ride comfort have already been introduced.
The damper efficiency related to the reduction of the bending carbody vibrations rises along with its length.
The introduction of the anti-bending dampers will trigger the reduction in the level of carbody vibrations, due to bending.

The investigation is conducted on the Ordzhonikidzevsky mining and processing enterprise (MPE) for the reported data for 2014-2015.
The actual cost of 1 ton of manganese ore in the reporting period was increased by almost 5% due to the reduction of ore production.
According to the enterprise’s data, conditionally fixed costs in the total costs for mining of overburden by the bucket wheel complexes are 60-70%, ore extraction are 33-38%, production of concentrate are 46-50%.
According to the data for December 2015, the coefficient Kc.l of coincidence of production volumes, which are smaller volumes of shipment, is equal to 0,36, the coefficient Kc.m of the coincidence of volumes of production, which are larger volumes of shipment is 1,27.
As a result of data analysis in June 2015, the coefficients of the coincidence of production volumes were set as following Kc.l=0,42, Kc.m=1,43.

The reduction effect of water pressure is more and more obvious from the tunnel crown to the elevation where the drainage holes are provided.
The reduction effect of water pressure is more and more obvious from the tunnel crown to the elevation where the drainage holes are provided.
Generally, for the invert is closer to the drainage hole, it enjoys better reduction effect regarding to the water pressure behind the lining walls than tunnel crown.
Nevertheless, for the water pressure behind the walls at the tunnel crown represents the overall characteristic of the water load reduction around the segment lining, it is still recommended to take the water pressure behind the walls at the tunnel crown as the reference for evaluating the reduction effect.
It is worth mentioning that: the quantitative data in this paper is gotten under special physical mechanics parameters for water head and wall rock, which can only be used as the reference for similar projects rather than for direct design.

In this paper, the method of wavelet domain adaptive filtering was used to de-noise NMR echo data.
The effectiveness of the wavelet domain adaptive filtering in the de-noising of NMR data was demonstrated.
Many scholars at home and abroad have discussed NMR data de-noising based on wavelet transform [1-3].
The wavelet domain adaptive filtering method, however, has not been used in NMR echo data processing.
Noise was added into the echo data after forward transformation to reduce the SNR to 10.

Data evaluation is crucial for gaining information from sensor networks.
ML is a suitable approach for the evaluation of sensor data [4].
Hence, agents can carry learned models separating code (ML algorithms) and data.

Results of trades for First Price Zone, February 2014, data from the Trading System Administrator, Russian Federation [2] At once, this difference abroad can be assumed approximately as 2÷2.5 (fig. 2).
The cash equivalent of bonuses for system efficiency is determined from the following data: - cost of fuel’s consumption reduction on CHP stations; - additional profit from the reduction of greenhouse gas emissions into the atmosphere; - reduction of the repair expenses for CHP’s equipment.

Asama et al. proposed the Intelligent Data Carrier (IDC) with the aim of sharing knowledge among the robots [4]-[6].
(The data’sis low and each of the data size is smaller than a storage.) 3) CASE 3 Sharing like Distribution The data file is stored among several modules as multi-files.
(The data is less frequently referred and the size is very large.)
And the rarely referred data must be archived or deleted from the storage.

Data Processing This paper selected the data of China from 2001-2010.
Because the various indicators of the evaluation index system have different dimensions, we use non-dimensional formula as to obtained the standardized data which ensure the data is not influenced by the dimensions, whereis original data, is the mean of original data, is the correction for the standard deviation of the original data.
And we got two common factors of input indicators about environment-friendly, where for pollution reduction factor, for environmental factor.
According to factor score matrix, the factor scores can be calculated by using regression and the original index data.
There are five input indexes: -------resource consumption factor;-------economic contribution factor; -------elastic coefficient factor; ------- pollution reduction factor; -------environmental factor.

Experimental Results Calibration of SPV data.
From the data in fig. 2, a region ranging from about 200 µm to 300 µm is probed by SPV measurements.
A more accurate estimate of the palladium concentration can be obtained by using the data in fig. 2.
The data in fig. 2 were used to estimate the palladium concentration from SPV diffusion length measurements.
These data were used to calculate the reduction of the palladium concentration obtained by the barrier layer and by wet cleaning (see table I).

Research on the key technology of vegetation roofing energy saving Bao Xuefang Department of architecture & urban planning of Anhui institute of Architecture & Industry, China Email: 984813129@qq.com Keywords: vegetation roof planting technology energy-saving emission reduction ecological landscape Abstract: This paper focuses on the key technical requirements of roof vegetation, using contrastive method analysis of vegetation roofing heat preservation, heat insulation performance advantages and energy saving and ecological landscape effect, to study the climate vegetation roofing greening plant key technology and application.
Vegetation roofing energy-saving emission reduction effect Energy saving and economic benefits mainly with insulation in summer and heating in winter in roof greening effect, can effectively overcome the influence of summer extreme climate in hot summer and cold winter area of hot, cold winter, improve the building environment microclimate, save the air-conditioning and heating or cooling load, reduce the pressure of city electricity, energy saving
(1) analysis of roof green insulation, insulation performance Green roofs have "natural air conditioning", has a certain heat preservation, heat insulation and energy saving effect,It likes a warm cover the protection of buildings in winter, roof greening in addition to the insulation layer outside the heat insulation effect, the vegetation layer and the planting soil layer also has the performance of double heat preservation, According to the roof greening Hefei area and control area (cement roof) recording observation data: green roof after the indoor temperature increase compared to 2 ℃, (Fig.4) winter warming effect is obvious, double insulation can basically meet the requirement of thermal comfort in buildings in the area.
Vegetation roofing vegetation in the summer, vigorous growth, with luxuriant foliage plant growth, photosynthesis will most of the solar energy into biomass, solar radiation heat and reduce the direct effect on the roof, at the same time, planting grass roof thickness increased, gain ability to resist the external thermal effects, Summer (August) afternoon 14 when the roof greening and the control area of the roof temperature observation data recording, the control area of the common roofing temperature is 50.5 ℃, the green zone temperature is only 35.4 ℃, 15 ℃ floor temperature difference, the indoor temperature 1.5 ℃ contrast decreased (Fig.), so green roof can Fig.4 Vegetation roofing and the common roof and test temperature control effectively reduce the temperature of the roof and the summer indoor temperature, reduce air conditioning load, to achieve the purpose of energy-saving insulation.
(2) vegetation roofing reduction effect Air is the necessary material conditions for human survival, city of oxygen consumption of dense population, the high concentration of carbon dioxide, green plants producing oxygen absorption of carbon dioxide, the ground greening area limited, roof greening of atmospheric oxygen and carbon dioxide balance play an important role.
