An FE model of a spindle unit is created and validated with experimental data by solving an optimisation problem.
It has not only to be capable of driving the tool but also of transferring energy, media and data at the same time.
Figure 4: Measured and calculated frequency response functions Concepts for the transmission of media, data and energy This section deals with possible solutions for transmitting energy, media and data through the hollow shaft taper and the spindle shaft.
Concept 2 shows the greatest reduction in axial stiffness.
An FE model of a spindle unit was created and validated by using experimental data.

This oxidation peak will usually have a similar shape to the reduction peak.
Furthermore, by compare the test data of two groups of the samples, one is 0318, MCMB22, AGP-3-2, and another is 0318-GLQ, MCMB22, GP-3-2-2, we can see that mixed processing may be uncertain about the performance improvement of the first efficiency, and even worse.
From the data listed in Table 3, we can predict the reversibility of AGP-3-2-2 is best, and AGP-3-2 is worst.
From the experiment data in Fig.1, we can see the high-rate performance of AGP-3-2-1 is superior for the first cycle, but for the 2nd and 3rd cycle, the peak current of AGP-3-2-2 is greater, so the rate performance of its is superior, According to the test results in Fig.1, the high-rate performance of the samples in the order is: AGP-3-2-2 > AGP-3-2-1 > 0318-GLQ > 0318 > MCMB22 > AGP-3-2.
By the comparison analysis of the data for 0318-GLQ, 0318 and AGP-3-2-1, AGP-3-2, we know the pitch-coating modification have a positive effect on improving rate performance of the material. 3 Conclusions 1) The surface conditions of different materials will be a big difference, modification of materials will change their surface state, and then effect the formation of a uniform SEI film, which is an important factor for the electrochemical performance of battery.

Data fusion usually has three links: Data acquisition, feature extraction and reasoning decision.
It has tree three levels: Data level, feature level and decision level.
It provides data reduction to feature level.
In feature level, data of images can be classified in computer.
The data processing efficiency of decision level can be improved by this step.

The results show that slow cooling in any temperature range leads to strain reduction.
The cooling gradient in this paper is defined as positive and refers to a reduction of heater temperature.
This is a reduction of strain by 60% in comparison to C1.
Looking at the data in Fig. 3 it becomes obvious that the largest differences between the ingots exist in the top and bottom of the core area and the central mantle area.
The data also suggests that if coating is done properly, the effect of the crucible constraint on the Si ingot is not significant.

Statistical Design of Experiments (DOE) Statistical design of experiments (DOE) is a widely known experimentation technique used in such cases, where experiments are carried out to determine the effect of an independent variable on a dependent variable and the relationship between them, using a regression model based on the experimental data.

New stringent emission limits require the drastic reduction (80 to 95%) of harmful emissions of NOx and PM.
For this latter purpose, on-board monitoring data will be combined with open-source data such as AIS and waterway characteristics.
Furthermore, many vessel engines are so old, that no type approval was ever performed and no emission data is available.
Obtaining precise data about the power output of the engine is one of the problems that occur in measurement setups on a vessel.
Conclusions New stringent emission limits require the drastic reduction (80 to 95%) of harmful emissions of NOx and PM.

After a reduction of 80%, minor part of GNBs acquires high-angle misorientation.
At the same time the YS in the transverse direction tends to increase with increasing reduction from 60 to 80%.
However, there are a limited number of studies dealt with the effect of rolling reduction on anisotropy of these alloys.
The G component is essentially stable at all reductions.
These data supports the basic idea of the formation of α-fiber extended from G to B components (Fig.3e) that deformation banding is essential for the development of the brass-type texture, because it requires the relaxation of a constraint that is not allowed within areas with uniform distribution of lattice dislocations [15].

In addition, these experimental data were investigated using Taguchi approach to find the effective parameters of mix proportion.
The details of each HSC mix proportion used and the average retained strength data for each mix proportion are listed in Table 2.
A statistical analysis is performed to determine the statistically significant factors and the data analysis is presented in Tables 3 and 4.
Even thought, both decrease considerably, their reduction percentage is not associated
· Using these data, we have checked the data with Taguchi approach and it is found that the water to binder ratio is the most important factor in mix proportion in both compressive and tensile strength.

According to the formula (1), (3)and the data above, estimated that the energy consumption is 5.41 PJ in 2010 in GanSu province.
Choose the star-rated hotel statistical data of GanSu province 2001-2010 which from the yearbook of China tourism statistics as estimated sample to estimate the energy consumption of star hotel.
The data shows that the tourism in GanSu province belongs to the low energy consumption and low CO2 emission industry
The data shows that tourism transportation’s energy consumption and CO2 emission occupies the leading position
In the future, it is necessary to get more and detailed data and in-depth study for tourism detailed energy consumption and carbon dioxide emission status.

Due to the target’s structure and the viewing angle, multi-angle scan are demanded to cover target’s whole surface, which means data got from different directions need to be spliced together.
This method is accurate and reliable with the test of aircrafts data.
However, because of the linear propagation and complicated surface of objects, the scanner can only obtain parts of the surface data in one viewing angle.
Kd-tree is used to store and search the data.
(9) Results and Analysis The point cloud data we used are shown in Figure5.
