Results demonstrate significant reduction in Cr(VI) concentration, with a 30% and 50% retention on the clay support and the LTA-zeolite membrane respectively.
The synthesized zeolite LTA was compared with literature data in the zeolite database, revealing a well-defined crystalline structure within the cubic system [14].

Differential Evolution is utilized to generate inner polynomial parts and to find appropriate coefficients to experimental data obtained from other publications.
The function is optimized to fit experimental data from Dash and Makhlouf [7] with utilization of genetic algorithm and differential evolution.
Fig. 2 demonstrates the flow of GA-DE to search for good fit polynomials of the function to experimental data.
The dataset used here is experimental data earlier published by [7].
In addition, it can be clearly seen in Fig. 3b that the predicted porosity promisingly show good fit to the measured porosity of 9 validation data reported by Dinnis et al. [11].

The mechanical data for the corroded steel bridge is given in the Table 1.
These data are determined from the samples taken from the steel girder bridge.
Initial data for steel were obtained from French experiments of steel fabricated since 1930 [TCVN 11297: 2016].
Entire bridge, there are 36 strain gauges and 8 deflection measuring points used, all data collected and processed by GTDL-620 data logger.
This reduction results in the reduction of elastic modulus and cross section.

To extract feature from the acceleration data, they convert three dimensional data into one dimensional vector using vector quantization [5].
Fig. 3 shows the example of raw data.
Fig.2 Data collection apparatus a) b) c) Fig.3 Accelerometer signals for different handwritten characters a-the data ‘0’, b-the data ‘3’, c-the data ‘9’ Feature Extraction Feature extraction is the elementary problem in the area of pattern recognition.
Therefore, we proposed a effective features fusion method from acceleration data in this paper.
PCA is one of the well-known dimension reduction methods.

The models assume statistical processing of the factual data array from real production facilities, which is produced using Data Mining tools, and special software is often developed [35, 36].
The initial MS Excel data tables had different header formats.
Statistical data processing followed by the construction of statistical mathematical models for 10Mn2VNb steel heavy plates, obtained in the 3600 HPM conditions, is performed automatically using MS Excel Data Mining tools.
The generated data array is processed iteratively.
The input data for the calculation is entered using the jQuery Universal Interface controls.

But, in case of the Carbon/PEEK composites, objective data is still very lacking.
The average of the result data from 5 specimens, except the highest and lowest data from the measurement data, was taken.
Generally, the graphs of tensile strength and bending strength were decreased according to the elapse of the immersion time, and especially the sharp reduction was shown in the graph before 20 days.
Also, the reduction of the bending strength according to the immersion time indicated the aspect which is similar to the tensile strength.
The following results can be obtained from these data
