Note: The energy consumption data of the train's air conditioning, lighting and other auxiliary system in the research have been included in the vehicle energy consumption
The data in 2009 obtained by the survey become the base of inertial model and through prediction for the parameters of calculation model, the prospective prognosis of traffic energy consumption and carbon emissions in Beijing has been carried out
(7) is the total station energy consumption (million kwh); is the station energy consumption of line i (million kwh); , , is respectively the number of station of ground open system, underground open system and platform door system; , , is respectively the average energy consumption of each kind of station According to the statistical data in 2009 provided by Beijing Subway Operation Company, the average energy consumption per month for the three classification station in air-conditioning month(June to September) and non-air-conditioning month were obtained, as shown in table 7.
If the low-carbontraffic policies, such as limitation of the car amount, adjustment of travel mode, reduction of rail transit energy consumption and trip time of car, are implemented, transport energy consumpation and carbon emission can be reduced up to 16%, which will be benefit to the development of low-carbontraffic.

M nodes on the surface of the ground can be selected according to the measured data.
The measured data (right) is also plotted for comparison.
It can be found that the simulation results are consistent with measured data considering the amplitude.

Adsorption equilibrium data for each adsorbent were obtained at pressure up to 1.5 atm.
These diffraction data reveled that Na-X retained high crystalline phase, as evidenced by sharp diffraction peaks at high angle [6].
The diffraction data also demonstrated that no A-type zeolite was present in the adsorbent samples.
Cation exchange gave no damage to the zeolite framework, and furthermore, no reduction in the crystallinity of the ion-exchanged X-type zeolites.
Adsorption equilibrium data for nitrogen and oxygen onto the ion-exchanged X-type zeolites measured at 20 o C and at pressure up to 1.5 atm revealed that Li-X adsorbent showed the highest nitrogen adsorption capability at high equilibrium pressure.

Two strain rates (0.1 and 1s-1), three strains (40%, 60% and 70% thickness reduction) and four temperatures (20, 200, 400 and 600°C) were used: providing a total of 24 deformation conditions.
The EBSD data was acquired in the mid-thickness section of the long transverse plane (plane containing rolling direction (RD) and normal direction (ND)) while X-ray data was acquired on the rolling plane (plane containing RD and transverse direction (TD)).
Data analyses were conducted for g and q fibre grains.
X-ray peak profiles were used to evaluate the dislocation density and X-ray resolution function [8,9], while from EBSD, data for average point-to point misorientation (GAM or grain average misorientation) and number of high angle boundaries inside a grain were determined [10].
Conclusions The highest reduction of 70% shows a clear increase of in-grain misorientation at intermediate deformation temperatures (200-400°C).

Campus energy consumption per unit area in American Research University is higher than most building energy consumption; especially the 24-hour operation of the laboratory and data center consuming a lot of energy, and the total energy consumption of school buildings is second to the comprehensive consumption of various types of office buildings.[1] It has become an undisputable problem that colleges and universities energy consumption is the social major energy consumption, so building energy conservation has come to a critical state in colleges and universities.
In recent years, along with the sustainable development thought is deeply rooted in the hearts of the people gradually, energy conservation and emissions reduction of colleges and universities in our country has been not stay on a conservation-minded campus propaganda and demonstration projects, but the green concept into campus construction and operation management.
Researching energy consumption quota of colleges and universities is one of the important measures to promote energy conservation and emissions reduction.
Through data processing of 41 colleges and universities building energy consumption in Hubei, we came to the conclusion that the per student average energy consumption index of engineering and agriculture in colleges and universities of 211,985 is higher than of liberal arts in colleges and universities generally, generally high to 35.8%; the per student average energy consumption index of engineering and agriculture in colleges and universities of 211,985 is higher than ordinary engineering, general high to 11.08%.
The quota according to the distribution of energy consumption to formulate, and by the combination of related departments of punishment and reward can easily promote the enthusiasm of colleges and universities on energy conservation transformation, but for building samples quantity, data accuracy requires high; The method according to per student building area to formulate is the most scientifically rigorous, And has more advantages to colleges and universities, which is difficult to obtain the accurate energy consumption data in energy measurement, can effectively promote the energy conservation work progress.

Sheltering effect was exhibited by the seaward macroroughness elements, showing significant reduction in the front face pressures.
All data were recorded at the sampling rates of 50 Hz except for the flow velocity (40 Hz).
Baseline condition (Case 1) as shown in Fig. 3 was first tested and used as reference data for comparison.
The pressures are found to be reduced relative to the baseline and the reduction percentage is getting slightly higher for the pressure at higher level.

Universal Remote Sensing Parallel Process Framework As mentioned before, remote sensing data processing has its own distinct characteristic: data comes from multiple sensors (such as optical cameras, SAR, e.g.), multi-types of data processing (such as radiometric correction, geometric correction and fusion, e.g.).
Fig.1 Data flow of framework Structure of the Framework The framework is built on message passing, through message passing interface (MPI), the data is sent and received.
Task divider: divide the data to each computing node.
The data source is high spectral data captured from the unmanned aerial vehicle, with 128 bands and 1030 pixels in each line.
From the curve trend, we can see the reduce rate is not linear, the computing time will reach a relatively stable stage after a sharp reduction.

The test results displayed that the settlement reduction ratio of the stone column ranged from 1.12 to 2.18.
Each test was thoroughly instrumented to collect critical data about the load-support mechanism.
After preparing the test sample mold, an earth pressure cell (EPC), with a capacity of up to 1 MPa, was installed to monitor stress data.
This system collected data on the stress within the composite ground, the settlement, and the excess pore pressure.
Stress-Time The stresses on the column and soil were measured using data from sensors installed beneath each respective layer.

The efforts for implementing green manufacturing activities involve product design changes, the development of new raw materials and the reutilization, recycling or reduction of production wastes.
As data collection procedure to examine the selected case, the semi-structured interview method was chosen because it is considered the most adequate method for collecting data in qualitative research [23, 24].
Patton [25] also reinforces this recommendation saying that the proposed data gathering method should be used when the researcher needs flexibility to obtain information in any direction that could be required, which is the case in this exploratory study.
End of process controls Is there a program for reduction of gas emissions?
The case study makes clear that a company needs the support of its suppliers to improve the environmental conditions of its supply chain, especially when it requires from its vendors actions like reduction, reutilization, recycling, redesign, recuperation and re-manufacturing, all them vital for a better environmental performance.
