With the further reduction of the axial height (z/T), w attenuates quickly along the axial, and the position of maximum axial velocity moves to the direction of 2r/D increasing.
Through the analysis of the experimental data, the boundary linear expansion equation of upward axial flow can be expressed as Eq. (1).
The experimental data shows that fluctuating velocity values of the impeller discharge flow are significantly higher than the main loop region, turbulence intensity of impeller zone and impeller discharge flow region is bigger.
As there are only tangential and axial velocity components in the data of the experiment,so we assume local isotropy,than Eq. (2)can be simplifiedasEq. (3).

At small set rolling reductions, the observed pressures are generally between 85MPa and 260MPa.
Nominal stress-strain data for aluminium alloys Table 3.
Summary On the basis of the compression data analysis the quantitative relation of the material’s yield stress in function of the kind and content of alloying elements was demonstrated.
Similar conclusions can be reached by analyzing the data of changes in the hardness during cold rolling and the values of average pressures, obtained in the process of cold rolling.

This modelling method presents an easy and uniform way to prepare appropriate data for computer DTFM algorithm.
The Jeffcott model (Fig. 2) parameters are equal: I=0.03 [kgm2], I1=I4=0.02488 [kgm2], I5=0.5 [kgm2], I2=I3=5.981 [kgm2], C=C4=3141.59 [Nm/rad], C1=C3=154625.263 [N/m], C2=2·108 [N/m], TF=TF1=Dg/2=0.1 and they have been calculated for the following data: E=2.1·1011 [MPa], G=8·1010 [MPa], l=0.8 m, dg=dp=0.02 [m], Dg=Dp=0.2 [m], h=0.02 [m].

The significant factors, their interactions and the optimum
setting are presented in this paper
Introduction
Rapid Prototyping (RP) is a process that is used for fabricating solid prototypes from a computeraided
design (CAD) data file [1].
RP is finding its applications in diverse fields of industry today, with prototypes used for form, fit and function, design verification, early detection of error and reduction of waste [2-3].
Two-level Three-factor Full Factorial Experiment Data Analysis Based on the results in Table 3, the column effects containing the three way interaction can be ignored in the analysis due to their low effect on the results.
Three-level Two-factor Full Factorial Experiment Data Analysis The nine experimental trials were conducted by testing the combination of factor levels from Table 2 in the experimental design matrix for each trial.

A goal of this research investigation
has been to provide quantitative data on metal release rates of bioactivated Co-Cr alloys when
exposed to different media.
The data statistical treatment was performed with a Medcalc program for biomedical application.
MTT Assay, is based on the enzymatic reduction of yellow MTT, 3-(4, 5-dimetiltiazol-2-il)-2, 5- difeniltetrazolium bromure) to an amount of formazan which is directly proportional to the number of viable cells.
Analyzing the data contained in Table 2 is evident that the current density, respectively the corrosion rate is lowest for the electrochemical deposition in comparison with the untreated and chemically treated in PBS, lactic acid and citric acid.

Voltage and current data that are directly obtained from the tests are processed with Microsoft Excel.
Because of the rate oxidation and the rate of reduction are equal then this line equation is equivalent.
The Result of Polarization The resulting data is processed using auto lab and the NOVA 1.8 program.
The results of the processed data display a graph of the current value for each potential change, then expressed in the form of an E / Log curve i.
