The controller, Gc, with its optimal parameter can be obtained by inverse identification using the original plant model from a simulation data.
Fig. 2 illustrates the simulation that can be used to generate the data for identifying the controller.
(11) Five hundred PRBS data points are used to generate the controller identification data as described by Fig. 2.
Using this data, the controller parameters for structure (4) is obtained using inverse identification.

The increase in OK condensation degree led to the reduction in the molecular weight of PEKS.
These results correlate well with the data on PEEKs in literature [8].
All the results of the IR-spectroscopy, turbidimetric titration, elementary quantitative analysis and data on the determination of the intrinsic viscosity confirm the fact of obtaining PEEKs of the proposed structure.
The obtained TGA data is shown in table 1.
This is evidenced by the data given in table 2.

The relationship matrix can be put into the Bladed to combine the data, and then use the Bladed rainflow to get the equivalent stress.
A set of matrix data like above can be got through many times load calculations and different annual average wind speed statistics.
After analyzing these matrix data, each load conversion matrix is very similar.
In the purpose of the data as accurate as possible, multi-group calculations can be done to enrich the database, such as obtaining the fatigue loads and the load conversion factor matrices at different air density.
Based on these data, the component which have large stress and large percentage is the dominant load component.

This article will evaluate the city air quality grade through the air quality indicator data of the 31 provincial cities and municipalities.
At the same time, a two-dimensional diagram showing the various states of two kinds of property variables visually describes the original data structure. pij represents the i-th state variable A and variable B while the j-th state probability.
Before the clustering, to eliminate the impact of index data units, so the first raw data were normalized.

Neural network detection module determines it is abnormal while the IFS detection module regards it as normal data then submit it to the management of interpretation.
For normal data, generate a sample of the sample library to avoid duplication of miscarriage of justice; for abnormal data, make the neural network training examples and IFS rules, improve the capacity of system to identify new invasive variant invasion.
Due to the large amount of the KDD dataset, the random sampling of 47879 has been used as the experimental data, which include four categories types of attacks (DoS (denial of service attacks), Probe (probe attack), R2L (remote to the local attack), U2R (user to root attack)) and normal data.
Table 1 reports the statistics of the detection rate of all attacks in the test data, which shows that for most of attacks, detection rate based on the proposed model has been significantly improved; Table 2 gives the comparison results of the various models, which shows that the accuracy rate has been improved to some extent.

The dielectric data measured at 1 MHz were used in order to minimize contribution from the conduction.
The data was measured at frequencies of 100 Hz, 1 kHz, 10 kHz, 100 kHz, and 1 MHz.
Fig. 4 (b) shows the dielectric loss data of the sample with x=0.7, which were used for the fit.
It was found that the Vogel-Fulcher relationship gave a reasonable fit to the experimental data.

The strip produced by TRSC has the potential to compete with hot strip rolling because a large saving of energy and heavy reduction of CO2 emission are expected by this near-net-shape casting technology.
When the liquid metal was poured into the chamber, temperature data were collected by data acquisition system which linked on an industry computer.
Three different thickness chambers generated three different cooling rates, according to the measured temperature data, and the cooling rates decreased with increasing thickness of samples, with their maximum cooling rate was about 3624k/s, 365k/s and 130K/s, respectively.
So it is necessary to obtain the data of the linear contraction rate.
Substitution of these data to Eq.(1), the linear contraction rate can be gotten.

The carbon fibers modulus values show a relatively wide variance of data which would be caused by a small indentation depth, lower than ideal conditions.
For each of five evaluated areas (5x5 μm) before or after sterilizations the SPM formed images with 256x256 data points, i.e. the distance between two indents is approx. 19.53 nm.
So, the statistical evaluation was carried out on data with sample of size 65,536 for each evaluated area (i.e. 65,536 storage modulus values).
Fig. 2 An example of statistical evaluation of storage modulus of 256x256 data points in modulus mapping of CF/PDMS composite after 300 minutes of sterilization In Fig. 2, three peaks of pixel counts can be observed.
A scatter of 20-25% in the mechanical data obtained from nanoindentation of estimated fiber/matrix interphase region can be also attributed to factors named above.
