The possibilities to roll such gear wheels will be compared to wheels with the same number of teeth but with a module of 1 mm which is significantly smaller.
It is expected that gear rolling has a number of advantages in improving the strength of a work-piece in comparison to other traditional methods.
Neugebauer et al. [6] presented their latest findings in the field of gear rolling by introducing a number of innovations in the rolling of helical gears.
This initial action will divide the work-piece into the required number of teeth i.e. 26.

This can be used to vary the bilayer number (n) from 1 to 50 to 150, thus modifying the bilayer period (Λ).
It is observed that the coatings with the highest number of bilayers, are more resistant to wear than the samples with a smaller number of bilayers.
Is observed the influence of the number of bilayers or bilayers period on the structural characteristics of multilayer [10].
Broadly, the multilayer progressively decrease the coefficient of friction by increasing the bilayers, this is because of the improvements in mechanical properties and reduced surface roughness, since by increasing the number of interfaces decreases interstitial spaces generated a decrease in grain size.
This was attributed to the surface homogeneity, achieved by increasing the number of bilayers.

A significant number of micro-pores were present in the melted layer for AA2124 treated with high number of laser pulses, leading to the decrease of the corrosion resistance. 1 Introduction Aluminium alloys possess good corrosion resistance for most environmental exposures due to the natural oxide film on the surface.
The effect of the applied number of laser pulses per unit area is also considered. 2 Experimental The nominal compositions of the investigated commercial aluminium alloys AA2124-T4 and AA6061-T4 are given in Table 1.
The number of laser pulses per unit area increased from 10 (10P) to 25 (25P), and 40 (40P), and the frequency was constant at 10 Hz.
Undissolved Al2CuMg (S-phase) and Al2Cu (q-phase) in solution treatment, which were preferentially located at the grain boundaries, were also found in the alloy.
The melted depth increased with increasing number of laser pulses for both alloys, which is believed to be due to the repeat of the melting process with multi number of laser pulses.

Al2O3 was deposited at different laser energies(700 mJ, 800 mJ, and 900 mJ) with different number of pulses (100, 200, 300).
This is due to an increase in grain defects, as well as an increase in thickness that caused a poor cohesion of the Al2O3 nanocoating[30].
A number of techniques have been developed to obtain a quality improvement of a multi-characteristic product.
The number of pulses is also directly proportional to the surface roughness and inversely proportional to the hardness and energy gap. 4.
The grown nanocoating thickness was increased as the laser pulse energy and the number of laser pulses increased.

Results and Discussion Figure 1 shows the field dependences of differential magnetic permeability µd(H) for the specimens tested for zero-to-tension cycling with different numbers of cycles n.
Figure 2b shows applied tensile stress dependences of the peak of differential magnetic permeability md max for the specimens cyclically preloaded with different numbers of cycles.
The dependence md(H) for the specimens tested for the zero-to-tension cycling with different numbers of cycles n: n = 0 (curve 1), n = 30,000 (2), n = 50,000 (3), n = 100,000 (4), and n = 300,000 (5).
This confirms the inference that the level of residual compressive stresses induced by cyclic preloading increases with the number of cycles.

Therefore, features and trends of edge detection based on GM(1,1) can be summarized as: 1) Determination of the pixel number in grey modeling.
Now, the number of pixels in GM(1,1) in most case are fixed, such as four, nine, twenty-five etc. 2) Determination of the threshold in judging the prediction error.
For example, the data sequences are preprocessing before the Grey relational grades are calculated or after the edge detection is finished, some improved measures are implemented. 5) Compared with the technique based on GM(1,1), the methods based on Grey relational analysis are more mature and approaching to specific applications, such as crack detection of the pavement image[24] and edge detection of pests in stored grain image [14], and the image type is extended from visible-light image to remote sensing image and IR image. 5 Conclusions Currently, although the application of Grey theory in image processing is far from maturation and has a long way to go before it is widely used like fuzzy theory, more and more researchers at home and abroad have paid attention to Grey theory for its feasibility and efficiency in image engineering [2].

National Development and Reform Commission said they adopt fiscal policies to support, support part of the grain into fuel ethanol, To the end of Eleventh Five-Year, the proportion ethanol gasoline consumption accounts for the national gasoline consumption increased from less than 20% to over 50% [7].
An explanation is that the temperature rise of seawater caused to a large number of gas hydrates decomposition, the greenhouse effect caused by methane gas made the global temperature increase suddenly, and the oxygen deficit of seawater resulted in a large number of marine organism extinction and migration.

So far, it has a large number of high conductivity of solid materials to replace the liquid electrolyte.

It has the following advantages:(1) one condition was added to model RNG-, the accuracy was changed obviously; (2) the Turbulent vortex was considered, and accuracy was changed twice; (3) RNG model provide a kind of analytic formula because low Reynolds number viscous flow, these formula could treat some wall conditions more accurate.

Because only 10mg fuel was carried out in fast pyrolysis experiments, treat the sample grain as a little cylinder grain at locale, and adopt heat depth 0.02, 0.05cm.

In the cross-section HR-TEM image three layers are clearly visible: a SiO2 layer in direct contact with the Si substrate, a bottom 8 nm Pr-oxide based layer having a different contrast than the SiO2 layer and no long range order, and well defined Pr2O3 crystalline grains.
The shift value can be used to quantify the number of fixed or trapped charges (Nf, Not [cm -2]) in the dielectric films using the equation: eA VC N ∆ = where C is the accumulation capacitance, e is the electron charge, A is the area of the gate and ∆V is the flat band shift.
The number of trapped (negative) charges (Not [cm -2]) has been evaluated from the hysteresis observed in the C-V curve and it is quantified as Not = 1.6×1011 cm -2.
These defects can be mainly referred as bulk defects and appear not to be related to morphological defects such as the presence of grain boundaries.
