The creep test data were recalculated for operational temperature using Larson-Miller parameter.
Experimental creep data were approximated by several equations.
Interpolated values are congruent with experimental data.
For those points computational data were collected.
The data confirm the performance of power calculations and analysis performed.

With the knowledge given by a tracking filter in data processing, the KA-C-STAM improves the performance of angle estimation.
A fact of significant is that the distribution of current angle of the target is non-uniform if one consider about data of all of the CPIs before.
In data processing, the tracking filter gives a predicted angle on which the probability of the appearance of real target reaches maximum.
One can notice that the angle of target is estimated based on information from both signal and data processing.
A new feedback structure exists beyond the signal and data processing domain to the feature domain.

The research showed reduction in cost and cycle time of new parts development.Lee et al. measured compressive strength and it was shown that parts made by FDM, 3D printer and NCDS have anisotropic characteristics [27].
Xiaomao et al. proposed and tested a robust and efficient support generation algorithm based on slice data [29].
By comparison between the measured data and computed values, the validity of the proposed expression was proved [30].Galantucci et al. studied the mechanical properties of FDM prototypes treated with a solution of 90% dimethylketone and 10% water have been analyzed [31].
In conditions of reduced roughness, a minor reduction of the tensile strength was found but a greater ductility was found.

The metal solubilization from
sulfide minerals is a chemical process which requires Fe
3+ reduction.
It was possible to correlate experimental data with a mechanism of bacterial-metal sulfide oxidation, the polysulfide pathway for acid- soluble metal sulfides.
Experimental data obtained in this work support the following conclusions: L. ferrooxidans gets its energy from the oxidation of Fe 2+ and, due to its metabolic necessities, favorably adheres to minerals, according with the indirect contact mechanism.

The optical absorption coefficient (α) of the films was calculated from the optical transmittance (T) data using the relation,
α = - (1/t) ln T (2)
where t is the film thickness.
The refractive index (n) of the films was determined from the optical transmittance interference data employing Swanepoel’s envelope method [25] using the relation, n(λ) = [N + (N2 – n02n12)1/2]1/2 (4) and N = 2n0n1[(Tmax - Tmin)/TmaxTmin] + (n02+n12) / 2 (5) where no and n1 are the refractive indices of air and substrate, and Tmax and Tmin the successive optical transmittance maxima and minima respectively.
A small peak observed at around 0.13 V may be attributed to Mo6+ reduction.
The presence of molybdenum leads to the existence of an additional peak related to the oxy-reduction of the molybdenum ions.
The presence of two reduction peaks was attributed to the existence of two predominant forms of tungsten and molybdenum oxide.

The Langmuir model compared to the Biosorption equilibrium data were best described by Langmuir isotherm model, R2=0.9999.
Biosorption has been considered as a promising technology for the reduction of toxic metals from industrials effluents and natural waters.
The biosorption course was very fast in the first 20 min .Biosorption equilibrium was established within 60 min. 3.3 Biosorption isotherm The Biological adsorption equilibrium constant obtained from Freundlich and Langmuir models for the Cr6+ biosorption onto A.niger are presented in Table 2. it is clear that both the Langmuir(Fig 4) and Freundlich(Fig 5) isotherm models accommodated to the experimental data, and model of the former is more suitable than the latter.

Surface characteristics of the samples were analyzed using Atomic Force Microscopy(AFM).Data collected were in terms of Surface Roughness (RA), Peak Vs Valley (P-V) and Surface Root-Mean-Square Roughness (RMS).
Result and Discussion Analysis of the surface characteristics are done using data collected from AFM which are in terms of surface roughness (Ra), maximum peak-to-valley height (P-V), and root-mean-square height (RMS).Surface roughness(Ra) is defined as the arithmetic mean of the surface roughness profile from the center line within the measuring length.
