The 6061 and 6063 aluminium alloy bumper unit has a weight reduction of 67% compared to the steel ones.
Then the response model for , and E (Fig. 7)were established by data from crash simulation results, which show below, (5) (6) (7) (a) (b) (c) Fig. 7 Response surface modeling of (a), (b)and E (c) relate to t and L The coefficient of determination () in the analysis of variance was used to verify the response of surface fitting degree.
After adopting the material of aluminium alloy, it has a weight reduction of 60% compared to the steel ones (weight 0.68 kg).
As a result, the new crossbeam and crash box satisfy both demands for improvement of crash worthiness and reduction of parts’ weight.
The new design unit can change the whole design of automotive parts for crash energy absorption, and definitely contribute to drastic weight reduction of steel parts.

In as world advocating carbon reduction, China still takes the leading position in regional production in Asia with its sustainable export-oriented industries characterized by labor-intensiveness, and its manufacturing industries have kept their competitiveness, despite the fact that there are several challenges caused by technological dependence and trade convergence.
Introduction In 2011on the 17th Conference of the Parties to the United Nations Framework Convention on Climate Change held in Durban, South Africa, it was determined to step into the second commitment period of Kyoto Protocol and launch the “Green Climate Fund”, which marked the establishment of the mechanism for international emission reduction.
Those supporting measures included: the government sponsored private businesses directly in respects of R&D and innovation, as well as introduced hi-tech and tax reduction policies.
Survival Conditions for China in the Regional Production within Asia Affected by Carbon Reduction Carbon reduction has spawned up the research and development of new technologies.
However, the data obtained by Lv Wei and Ma Mingjie (2011) in their research of the evaluation system for innovation performance has shown a paradoxical problem (although the researchers did not expect this conclusion): from 1995 to 2008, the index for innovation capacity of China’s manufacturing industries had quadrupled, realizing fast rise at an annual growth rate of 16%, but the growth in innovation capacity was not steady.

Twenty SEM micrographs, acquired at a magnification of 3000×, were taken into consideration to obtain relevant statistical data associated with these experiments.
The mean values and the standard deviations of obtained data were calculated.
In total, five samples were tested for each investigated condition, in order to obtain relevant amounts of data.
These data can hardly be compared, which may lead to confusing discussions and explanations.
The current results of fracture toughness measurements are in variance with the obtained data by Das et al. [15]; the main reason is that different experimental steel has been used for the investigations.

Figure 1 Region of interest (first: before compression, last: after compression of 28% reduction, middle: intermediate steps of ~5% difference in reduction).
The crystal orientation data described by Euler angles are further converted to quaternion representation and the in-plane rotation representation was achieved by projecting it along z-axis for a better comparison with the rotation result calculated by DIC [4, 5]. 5% 15% 28% Figure 2 Compressive strain maps (above) and rotation maps (below) around particle at different stages of compression.
Figure 3 (Left) EBSD misorientation map in the same region in Figure 2 with ε=0.33 (Red, Green and Blue colours are corresponded with the Euler angles between a reference pixel and the other pixels) and trace of {111} plane and (right) in-plane rotation calculated from EBSD data particle shape is outlined in green.
When the deformation goes up to 15% and 28% reduction, the strain in slip bands are up to almost 50% and 80%, with only ~10% in the between.
These agree with the EBSD data shown in Figure 3.

For the measurement of hydroperoxyl/superoxide anion radical concentration, the well known method based on ferri-cytochrome c reduction was used [11].
These data were collected at a power density of 1 W/cm2, with and without the single band filter in front of PMT.
For calibration purposes, ferro-cytochrome c was produced from the reduction of ferri-cytochrome c by sodium dithionite.
From these data, an average generation rate of 1.60 µM/min was calculated at ~ 27 °C.
Data. 14 (1985), p. 1041

Therefore, YSZ minimizes the electronic conduction of GDC as well as protects
the reduction of Ceria ions [3].
All data shows clear peak of yttrium and zirconium.
Comparison with other experimental data based on Ceria based electrolyte cell, our experimental results has enough potential[7].
We can conclude potential of this experiment from OCV data achieved by YSZ/GDC bi-layered cell.
YSZ thin layer seems to perform well to block reduction and electron conductivity of ceria.

Rough set theory [3, 4] is a theory of data analysis proposed by a polish mathematician Z.
Its main thought is to educe problems decision or sorting rules by knowledge reduction at the premise of keeping sorting capability.
The eigenvalues we get through the information collection, data processing in the experiments have are continuous values.
But the rough set theory can only deal with discrete data, so the first thing to do is discretization of data processing.

The temperature distribution across the window is measured and the data are used for the analysis of heat transfer through window.
The measurements were recorded in a data recorder.
The proposed PCM window system offers 8.8 % and 9.5 % temperature reduction when compared with the conventional system.
It can be concluded that the proposed double glass window with PCM is more efficient in heat gain reduction than the conventional double glass window filled with air.

The hysteresis curves show reduction in saturation magnetization in case of nanoparticles as compared to their bulk counterparts.
From the application point of view, the superparamagnetic blocking temperature (TB) of the nanoparticles used for recording devices should be well above the room temperature in order to have a stable data recording in these devices.
The stability of electronic and high density data storage devices made by magnetic nanocomposites is limited by their superparamagnetic transition.
Fig. 2 shows Langevin function fitting on the superparamagnetic M-H data at 300 K for S1, S2, S3 and S4 samples.
The values of saturation magnetization (Ms) were obtained by plotting the M versus 1/H curves and extrapolating the data to 1/H→0.
