The inclusion of an iron anode in the tubular-based electrocoagulation reactor results in a substantial reduction in color parameters, with levels reaching as high as 94.0-99.9%.
Data and Analysis.
However, a current between 125 - 200 ampere can still achieve a reduction color content of over 99%.
A significant reduction in the color content of textile industry effluents can be achieved with a current density ranging from 465.28 A/m2 to 823.19 A/m2.
Acknowledgment The authors would like to express their gratitude to the textile industries for providing the supporting data and sample of wastewater.

H-plasma treatment causes a significant reduction in concentration of these complexes.
Comparison of recent ab-initio calculations with experimental PAS data suggested that HTG ZnO single crystals contain Zn-vacancy + hydrogen (VZn+1H) complexes [1].
Experimental PAS data were interpreted using ab-initio theoretical calculations of positron parameters.
The concentration of VZn+1H complexes in the virgin HTG ZnO crystal cannot be calculated from LT data due to saturated positron trapping, but it can be estimated from the positron diffusion length determined by SPIS
Although there is a significant difference in the vertical position of calculated HMP profiles and experimental curves, the features predicted in theoretical calculations can be qualitatively seen in experimental data.

The associated parameters of membership functions change through the learning algorithm by a gradient vector modeling the input output data in case of given parameters.
Optimization method will be investigated to adjust the parameters according to error reduction computed by sum of the squared variation from actual outputs to the desired ones.
This adjustment leads the fuzzy systems to learn about the data modeling.
Its architecture is based upon an open communication structure in combination with the flexible electrical construction elaborating the moderated technology of future based on a new platform for dynamic exchange of data and information.
ANFIS membership functions are optimized automatically trough training so it could be more effective for various applications in data prediction which usually are constructed with complicated pattern.

This enhancement might be closely related to the reduction of residual stress and slightly large
grain, but its resistance was not affected by the anodic polarization behavior.
Some data showed that there is a similar effect of caustic concentration and temperature on the cracking of mild steel and Type 304 and 316 stainless steels [4].
The enhancement of the SCC resistance as shown in Fig. 1 and the reduction of susceptibility to SCC were not explained by these microstructural changes.
Variation of residual stress of anodic polarization curves of S32050 S32050 with thermal treatment By the experienced data [8] of nuclear power plants, it was reported that SCC problems were reduced largely as the grain size of Alloy 600 or Alloy 690 was increased.

With the blast furnace systems working for a long time, massive steady-state operation historical production data have been accumulated.
This historical data contain the physical system’s operation law which can be mined by neural network modeling method.
The main steps of comprehensive coke rate optimization by genetic algorithm are as follows: 1)Data preprocessing.
The comprehensive coke rate of blast furnace optimization research is carried out on the basis of historical production data, so the historical production data has directly effect on the optimization results.
For example, the objective function Y comes from the historical data’s relationship fitting by BP neural network model and each input parameter’s value range also comes from the historical data.
