It applied Taguchi method to solve problems in the reduction of processing load and thermal impact evaluation of the periphery by quill design and aimed to design an ideal tool form.
Taguchi Method Taguchi method is a kind of experimental planning method and refers to planning to obtain the maximum information about how to make experiments on the problems to solve, how to collect data and with what statistical method to analyze the data with the minimum number of times of the experiments.

The oxidation-reduction reactions that lead to the organic pollutants translate into CO2, H2O and some mineral acids occurs between electron–hole pairs and surface substance adsorbed by solid particle .
TiO2 possesses a wide band gap (~3.2 eV) so that its absorption edge occurs below 400 nm and only about 3~5% of sunlight can be utilized to promote the oxide to generate charge carriers which play an important role in the process of reduction and oxidation.
The calculated lattice parameters in comparison with available experimental datas are shown in Table 1[6].

It’s difficult to inhibit the noise of the measurement data and extract the gravity signal by classical algorithms.
The de-noising experiment has been emulated based on the measurement gravity data.
The commonly used method is used to process the data shown in Fig.3, and the result is shown in Fig.5.
Conclusion This paper presents a method of processing gravity data based on wavelet and EMD.
Filtering and processing for the airborne gravimetry data[J].

The
results indicated that using 3-APS as surface pre-treatment prior to coating resulted in a significant
reduction of total water absorption for alkyd on both mild steel and glass substrate.
These data are consistent with the known adsorption behaviour of 3-APS to steel, i.e. as an easily hydrolysed hydrogen-bond to the amine group, rather than as the more stable metal-oxide-silicon bond.
Thus each data point is represented by an average of thirty cross-cut test obtained from five panels.

Moreover, Current density-Electric Field measurements demonstrated a reduction of the leakage current and an improvement of the breakdown behaviour in the presence of the interfacial thermally grown SiO2.
Interestingly, a crystallization process of the Al2O3 occurred under electron beam irradiation during TEM analyses, in agreement with literature data [9].
While a higher conduction band discontinuity justifies the reduction of the leakage current, the better dielectric properties of the Al2O3/SiO2/4H-SiC MIS structures can be explained by a ALD denser Al2O3 growth in the presence of the thermal SiO2 template.

Higher fracture toughness material is obtained by
means of combination of reduction of Fe content and wider spacing between the constituents.
The data of whereεf* is the maximum strain Thompson et al. [4] are also plotted.
The newly developed 2x24 aluminum alloy sheets have been shown the potential of 20% thickness reduction or 30% weight saving in fuselage skins application [13]. 3) The seconds phase particles can be controlled element selection and process optimizations.

Recently, light-weight and energy-saving requirements for the automobile industry are extremely important in order to protect the environment by a reduction of the emission of CO2.
Introduction According to the E-Motive Steel Project proposed by the World Auto Steel (WAS) [1], in order to meet the requirements of safety and CO2 emission reduction simultaneously, it is planned to extensively use the advanced high strength steel (AHSS).
Comparing the cooling rate of 0.1℃/s and 0.04℃/s, the trend and data of TS and YS are almost the same.

It is shown that at high Froude numbers increasing the suspended sediment concentration to 28.7 gr/l leads to a reduction in the submerged depth on the gate up to 6% and jump length up to 10%.
This reduction is due to the return flow which contains a negative momentum and causes the flow to drop close to the gate.
By analyzing the velocity distribution data in different sections, they showed that the non-dimensional velocity distributions are similar in both the developed and developing regions.

After irradiation the epilayer material became more resistive, as indicated by the
reduction of the forward and reverse current density at a given voltage.
After irradiation the material become more resistive, as indicated by the reduction of the forward current density.
This confirms the data presented in [8].
