China’s civil car ownership and forecast If electric vehicles replace fuel vehicles in 10% of speed, specific data is as table 1.Obviously, in accordance with the above results, the widespread use of electric vehicles can save a large part of energy for society.
If pure electric vehicles account for 10% of auto possession by 2020, then each car will reduce 90% carbon dioxide emissions, and a 9% reduction of carbon dioxide emissions will happen in the auto industry, which will in return cause nearly a 1.5% in the overall reduction of carbon dioxide emissions.
Carries on standardized processing to the data and get the standardized computed result.

Reduction of pipeline deflections and stresses under certain loading level is the prerequisite of structural operability.
tu= p/2×DH×g×H(1+k0)tg(kjs), (3) where Н - in-soil pipeline laying depth (along the centerline); k0 – empirical parameter with recommended value (for normally packed noncohesive soils) 0.35-0.47; k – empirical reduction coefficient, the recommended value for pipelines with relatively smooth insulation surface being within 0.5 – 0.7.
Since the method of statistical modeling is a simulation of a real experiment, the use of experiment design algorithms and data processing algorithms proves to be fairly efficient for complex systems [3].
A typical compound diagram of failure-free operation areas, as represented in Figure 2, is plotted on the basis of the analytic data.

It results in significant reduction of time spent on the optimization process.
The feature of this stage is the cubic spline data interpolation method used to perform it. 5.
Definition of the relative incremental rate for the current power assignments using cubic spline data interpolation is performed. 7.
It also proves that the algorithm proposed can be used as a method of automatic hydropower plant regimen optimization taking into account the net head loss.The group active power control systems having the corresponding software will certainly lead to the reduction of water expenditure that will improve efficiency of hydropower plants and create a base for optimization of power systems regimens.

An important aspect of aggregation of knowledge is the fact that scientific data, database from producers and materials database are often not related to each other, and when they occur synergy that only partial, and their manner of representation, terminology and formats are not standardized.
Feature as a Representation of Knowledge The general definition of feature, describes the object as the unit of elementary charge, which stores the data, creates a network for the exchange of information, performs a service, thus realizing the overall goals of the system.
Taking into account the weight reduction of 12% can be considered the result as satisfactorily Discussion So contemplated structure, gives the designer flexibility in selecting the type of material for a particular layer in a particular area structural element.

Figure 3 shows the apparent porosity and flow rate of samples sintered between 1000°C to 1300°C.The flow rate results dependable with porosity as decreases the apparent porosity will reduce the efficiency of wastewater particles to pass through the sample that result in reduction of flow rate.
This occurs as the sintering temperature increases, the particles attached to the polymer network move towards each other and when the network collapse, can result in bulk shrinkage that lead to reduction of pores sizes and distribution.
From the pH data as shown in Table 2, there was an increase of pH value after filtered by Sayong ball clay membrane which is more alkaline of filtered water.
Data of COD testing shows that unfiltered wastewater gives highest COD value that is 299 mg of oxygen mass for every 1 liter compared to overall filtered wastewater.

Recently we have defined a new mechanical relaxation at low frequencies which stands for the alteration of the terminal zone in complex systems, in terms of a reduction of the mobility of the polymer chains.
But, the same increase of temperature gives rise to only a four times viscosity reduction.
The data are fitted to the percolation equation (see text).
Although the number of data is relatively scarce, it can be deduced that the percolation threshold is reduced as temperature increases, passing from approximately fc =2 at T=70ºC to fc =0.96 at T=120ºC.

Cq will be read from a data file or from an expression as a function of the valve lift given at the ports.
Get the data from performance map provided by the manufacturer which usually does not cover the whole operating range of the compressor and the turbine, so preprocessing functions are integrated in the AMESim model to extend the range of the map to a wider operating range.
The reduction the work sets of the propulsion system will lead to the decrease of the overall propulsion power as well as the decline of the maximum speed of the ship.
The reduction the work sets of the propulsion system will lead to limitation of engine's maximum speed as well as the maximum speed of the ship because of the same reason in Conclusion1.

Introduction Improvement of the thrust-to-weight ratio of Ariane V engine leads to the use of materials allowing a reduction in engine weight and an increase in mechanical performances.
For notched specimens, an extensometer continuously measured the diameter reduction.
A good correlation between calculated value and experimental data is found (fig. 4).

Other health benefits include reductions in postmenopausal symptoms and risk of osteoporosis in women.
These latter factors have been suggested to be the main mechanism causing the reduction in polyphenol content [3].

Introduction In traditional smelting process, ferromolybdenum was added to EAF in reduction period.
Relevant data by using of ferromolybdenum to smelting H13 die steel was analyzed to compare.
According to statistic data, nitrogen contents are lower for direct alloying with molybdenum oxides, and the average nitrogen contents are 90 ppm compared to 106 ppm from smelting process with ferromolybdenum.
