Statistics Indonesia [1] to reported data correspond with the Number of Motor Vehicles by Type, 2009-2013.
Sudin, et.al [2] were reported to review on the research performance of active and passive flow control on the vehicle aerodynamic drag reduction, and focusing the method to delay or prevent flow separation at the rear end of vehicle.
Post-processing of numerical simulation has presented the qualitative data such as velocity pathline and velocity vector, respectively, and quantitative data such as pressure coefficient (Cp), lift coefficient (CL) and drag coefficient (CD), respectively.
The velocity on the wake region become recover and contribute on drag reduction and downforce increase are correspond with increasing diffuser angle on rear body of the bus models.
Drag reduction are indicated by dcrease of drag coefficient with increasing diffuser angle on rear bus models.

At present, our country doesn’t have direct carbon emissions monitoring data.
According to industry statistics database provided by the export delivery value after 2008 and the difficulties of the data acquisition and accurate, this paper divides industries into 35 classes.
By looking at the China statistical yearbook and the energy consumption yearbook, we get the main energy consumption and industrial products’ energy consumption in our country from 2008 to 2012 through data sorting.
In view of this, the carbon cost of national industrial product must have a reliable carbon price to boost the development of carbon market, promote the country’s carbon emission reduction.
But in the long run, the implement of carbon cost may greatly contribute to the development of emission reduction techniques.

Noise reduction is the focus of several studies aiming at noise mitigation by technical approaches involving roughness reduction of wheel and rail rolling surfaces, optimization of wheel and rail shapes, modification of their structure and the use of different local shielding methods [7].
Past explorations have shown a reduction in noise of 6 dB by using tuned frequency dampers [9].
The NI cDAQTM-9174 chassis was used for the data acquisition.
By using the rail acceleration and impact force as input data, the rail’s receptance was calculated using the Fourier transform.

Data for concrete production were obtained specifically for this study in a Portuguese industrial facility and are registered in Table 1.
As the data for the background processes and for internal transport and electricity used in the industrial facility was not available, the analysis was carried out with data from Ecoinvent database [12].
If the scope, assumptions, data quality, scenarios or LCIA method chosen varies from one study to the other, the LCA results will be different.
In this phase of the material characterization, one can state that the concrete with fly ash incorporated may be classified as an eco-material (eco-concrete) considering that the environmental issues that are minimized are waste reduction, reduce of landfill problems and resource saving by the utilization of recycled materials.

As mentioned, a 10 kg reduction in the mass of the car increases its fuel efficiency by 40 m/lg.
The α-values ($US/kg) indicate the cost penalty per kg of mass reduction.
The α-values (lg/kg) indicate the CO2 equivalent per kg of mass reduction.

Particulate organic matters reduction of TADP was superior to that of MADP.
bAs CODCr Table 2 shows the reactors' performance data during the steady state condition at HRT 30 days.
If aimed at TWAS reduction, TADP is more suitable than MADP.
The VS reduction in TADP was same as that VSS reduction in MADP.
However, the VS reduction in MADP was lower than VSS reduction in TADP.

Strength is improved through the Hall-Petch effect [2] whist good ductility arises from a reduction in twinning as grain size is reduced [3].
To determine the annealing time to 50 % completion of restoration (t50) the modified Avrami equation is fitted to the data [9,10].
To determine the value of t50 the values of ∆σmax, n and t50 are changed until Eq. 1 fits the measured data.
It can be seen from the t50 data (Fig. 3) the binary alloys have the fastest restoration rate.
The greatest reduction in the restoration kinetics occurs when Gd is present and the Zn content is low.

This paper chooses Shanghai Hangzhou Bay north shore as the study area, to analyze the change of landscape pattern from 1994 to 2007, the data adopts 1994 aerial image and remote sensing image with 5m resolution of 2003 and 2007, land is divided into 11 types: urban land, rural land, factory, farm land, undeveloped land, beach, forest, water, fish ponds, road and railway.
Data resources The data of this paper are aerial images and remote sensing images, the images select 3 different periods which are 1994, 2003 and 2007, the image in 1994 is aerial image (1 meter resolution) and the other two are remote sensing images which are SPOT5 images with 5 meters resolution.
Using RS images as the basic information source, with 1:100000 map, other related maps, Shanghai statistical yearbook and other document data, using graphic splicing and geometric correction, gets 3 RS images of Shanghai Hangzhou Bay in 1994, 2003 and 2007 as shown in Fig.1.
Conclusion (1) The dominant landscape type in study area is farmland which CA is in the most significantwith most prominent change CA from 44.88% to 34.61%, an reduction of 10.27.
Area reduction of beach land was because that speed of artificial land reclamation was faster than that of natural formation of beach.
