On the other hand, EPD-GO had lower transmittance peaks of functional groups and hydroxyl
(-OH) group peak almost vanished due to partial reduction of GO occurred during EPD process as suggested by An et al.[12].
Thermally reduced EPD-GO (C2) coating had peaks at 1050 cm-1 (C-O) and 1555 cm-1 (C=O) which suggest an effective thermal reduction of GO and restoration of π network [13].
The constant phase element was used for the better fitting of the data due to non-ideal behavior of the coating which is represented by two factors: admittance (Yo) and n.

Until recently this approach was identified only with production optimizing where the target was to increase productivity of equipment by permanent improvement of the functioning of technical and technological equipment, decentralized repairs management and reduction of costs of life cycle of the machines [2].
Leaving any equipment without a systematic service may result in serious loss for an enterprise within a longer period of time, even in the areas where seemingly it is possible to rule it out e.g. the loss of data stored on computer discs.

Such kind of data shows a different pattern that the majority of data shows, so these data should be excluded from regular processing of data mining.
First, through the dimensionality reduction of the original data set, the execution time of detection algorithm could be lower.
Let d(o,o1) represent the distance between data o and data o1.
Otherwise, the data is considered as a normal data.
With a threshold T, the data set can be divided into two parts: normal data set and candidate outlier data set.

The technology evolution of the steering system provides a significant reduction in energy consumption.
To define energy efficiency in these hydraulic pumps were utilized data from the open literature.
In EHPS pump energy consumption was calculated from data of system maximum pressure, oil flow and pump efficiency.
In EPS, the energy consumption by the electrical motor during assistance was defined based on data from literature.
The Fig. 2 presents a simulation using data of Table 1.

Analysis can be conducted on real-valued continuous data, discrete numeric data, or discrete symbolic data such as characters.
The seven basic QC tools are employed mainly to achieve process stability; to create an understanding of and to determine guidelines for process improvement by means of reduction, control, and elimination of variation; to assess process efficiency; and to collect data for making management decisions.
The data were tranformed until mean = 0 and variance = 1.
(b) Time series data during January and April from 1996 to 2016.

Thanks to the continuous progress of communication, both the reference signals not only can’t fully meet the high rate of data transmission, but also affect the amount of data transmission and the utilization of resource blocks.
CSI-RS and CRS used in combination to achieve a higher data throughput, and to ensure the accuracy of the transmission.
UERS in LTE-A was also called demodulation reference signal (DMRS) which mainly used for PDSCH to demodulate data [4].
As is show in fig.3, I make LTE and LTE-A system bandwidth of 10M of simulation data comparison chart.
However, the local position of the curve will be a transient decrease or remain unchanged, because 6 resource blocks of the level of the intermediate frequency send PDSCH data that lead to a reduction with the 6 resource blocks have PBCH information and SSS information.

The limitations of current interferogram reduction software with Zernike polynomials in analyzing rectangular interferogram are illuminated.
Usually Zernike polynomials are used in the commercial interferometer data processing software to describe the aberrations[6].
It is important to note that the Zernikes are orthogonal only in a continuous fashion over the interior of a unit circle, and in general they will not be orthogonal over a discrete set of data points within a unit circle.
Analyzed by the interferometer data processing software MetroPro, the distribution of phase after reducing the alignment errors of piston, tilt, and defocus is shown in Fig 4.The PV value: 0.359, the RMS value: 0.041.Using Matlab computing software to finish the program of removing error, least-squares fitting to deal with the interference data, reducing the adjustment errors, accurate surface error distribution is obtained as shown in Fig 5.The PV value of the surface phase distribution: 0.355 RMS value: 0.038.
This is because usually rectangle interferometer is dealt with as a circular domain in the interferometer data processing software to finish Zernike polynomial fitting and also treated as a circular domain for the calculation of Seidel aberration coefficients.

The data obtained are used as the training and test samples to establish BP neural network models of ship’s maximum equivalent stress and maximum shear stress.
The training and testing are completed with the data tested by the shipyard and the correctness of this network is verified.

QT-length is increased from a reduction of tongue length through un-bending of QT-bend.
Material movements also take place for QL where the lip moves closer to profile center due to bending of QL-bend causing a reduction in QL-length.
For tests A and B, good correlation is obtained between reduction of QL and increase in QT indicating unchanged profile width.
Fig. 5 (b) shows the effect of minimizing stresses and strains in the tongue fibers by a reduction in tongue height from an unbending motion of QT-bend.
The effect was unfortunately not noticed until after the production test was concluded; therefore, data was not acquired regarding profile entry for the three tests, although mandrel diameter could affect profile entry angle.
