Such a steady decrease of fatigue strength in VHCF regime was not clearly estimated from our previous HCF (< 108 cycles) data [3].
The slope of curve for new alloy shows an unambiguous reduction below σa ≈ 170 (MPa).

One of the dose reduction techniques is use of the pulsed X-ray source synchronized with the detecting part [2].
The obtained data show the advisability of using the proposed technique for radiation dose measurements of the pulsed X-ray source depending on the tasks and for future dosimetry measurements of the different types of the pulsed photon radiation sources.

Then it is easy to understand why the Clapper-Yule model is darker than the measured, because the short distance reflection shortens the distance inside the paper, so part of light reflected without the paper’s reduction.
We could find the new model at the specific color (0B4), which is more familiar with the data we have measured.

One is that it can describe complex unstructured problems and the other is that it can realize the sharing of data[4].
In addition,due to the mass of factors and processes involved in the construction process and feature attribute for the construction cost control,this article does not consider the knowledge reduction.

It can be seen that sample with rutile formulation have the most effective formaldehyde neutralization with reduction to less than 10,000 ppb in one hour followed by biphasic samples and pure anatase sample with 20,000 ppb and 30,000 ppb respectively.
Summary From analysis and data obtained, it can be concluded that both anatase and rutile nanotitania are potential mediator for neutralization of formaldehyde.

In ANFIS, Gaussmf was used for training by input data patterns, and the study shows that ANFIS is the most effective method for predicting varied cutting qualities during hybrid machining operations [26].
For brittle material like Ti-5553, a reduction of cutting forces by 13% for a temperature of 5000C and for increase upto 7500C, the reduction in cutting force reaches to 34% [29].
Similarly Chip Shrinkage Coefficient was highest at 4500C and highest reduction in amplitude of vibration also occurs at 4500C.
For Inconel 718, Uncoated tungsten carbide SNMG 434 insert tool fails due to excess overheating above 630 0C. 73% reduction in specific cutting energy at Vc=66m/min, ap=0.8mm, f=0.13 mm/rev and MRR was increased by 228% [44].
It can be noted that there is a marginal difference in cutting speed due to the reduction in work piece diameter due to cutting by preceding tool.
