The order in which have been conducted the tests has been established through the use of the Minitab software, in order to ensure the data normality and the absence of auto-correlation between the tests.
An automatic procedure allows the drawing of the data in files containing numerical input and experimental data.
It also analyzes the obtained data comparing graphs in terms of fluid pressure, punch stroke and force for each actuator.
As it can be appreciated, thanks to the reported data, there is a good agreement between numerical and experimental values with a discordance of about 3 %.

In previous researches [1] I have investigated the feed rate influence on surface roughness and manufacturing time reduction.
The final results will be used as data for future research.
As to the productivity related to surface roughness, according to obtained data from the experiment, we found that the best ratio of these two factors is to the cutting regime: cutting speed at 530 m/min, feed per tooth at 0.14 mm/tooth and cutting depth at 4 mm, resulting a surface roughness of 0.212 μm.

Based on the data collected from the field assessment, the thermal comforts indices with expectancy factor were calculated.
Therefore, the radiant cooling technology was introduced and it was found that this type of cooling technology was effective in reduction of the air conditioners’ operating cost [3-4].
The field measurements and data collection were conducted for a period of five days (15/10/2012 – 19/10/2012) at level 2 - level 6 of the building, where the thermal environment for these five floors was measured.
The thermal comfort parameters in the building were recorded by using a thermal data-logger.
Measurements were taken in every 5-minute interval, and all the measured field data was transferred to the portable computer in daily basis for further analysis.

This paper started with analyzing the performance data of the plastic sheet molding material, using nonlinear finite element method and multi-physics coupling method to simulate the plastic sheet forming process, and the result gives the required parameters for product design and quality control.
And mechanical property constant C10, C01 is determined by the experiment, which is obtained by multiple testing and data fitting. 2) The geometric model and mesh configuration Simulation studies were focused on the common forming characteristics, such as cup drawing parts of different drawing ratio.
Based on the data obtained by photographic surveying the formed specimen with deformed grids, the ASAME grid Strain Measurement System gives the thickness distribution of specimen cup blow, as is shown in Figure 5 and then the thickness distribution of specimen cup blow can be obtained by data procession through ASAME grid Strain Measurement System, as is shown in Figure 6.

Other authors point out that compared to a wall without insulation or air gaps, an emission reduction of 60% can be achieved [16].
Section “Insulation materials” presents the insulating materials used in the retrofit intervention and, finally, “Imput data” section summarizes the parameters used to carry out the methodology.
The thermal conductivity values were extrapolated from standards [19] or, if not available, from data taken from product data sheets.

For this purpose, a phase-field model has been extended to allow for complex 3D anisotropic interfacial
energies and interfacial mobilities, calibrated by data from molecular dynamics studies.
The anisotropy coefficients are calibrated with data from molecular dynamics studies on pure Mg recently published by Xia et al
For the assumed anisotropy functions, based on molecular dynamics data for pure magnesium, dendrite arms are found to evolve only in <1120> orientations.

Hardening/softening curves, cyclic stress-strain curve and fatigue life data of coated and uncoated material were obtained.
Experimental data were approximated by the power law log σa = log K´ + n´ log εap
was used to fit experimental data.
The Coffin-Manson law log 2Nf = (1/c) log εap - (1/c) log (3) was fitted to experimental data and material parameters were evaluated using non-linear regression analysis.
Fig. 6 shows that experimental data of both materials are close to each other.
