Fast data transmission put forward high requirements on network content matching (NCM).
As the I-DFAs are equivalent to NFA states, if the is too large, it will result in sharp reduction in processing rate.
STT gets the transfer results according to the input data, Inner Transfer will be send to the State Combine model directly and the External Transfer will be send to TSJ.
Experimental data is selected from snort_24, snort_31, bro217 and dotstar_300.
(3) States Reduction For different regex expression set, States Reduction performance of DC-DFA is validated.

The highly Cube-oriented sheets were cold-rolled to various reductions up to 90%.  
In this study, the highly Cube-oriented Ni sheets were cold-rolled to various reductions, in order to clarify the stability of Cube orientation during rolling in such a polycrystalline Cube materials.
Firstly, the sheet 2 mm thick, 60 mm wide and 200 mm long was rolled by 50% reduction in thickness in one pass at room temperature, which is considered as the 1st ARB cycle.
Texture was analyzed by the orientation mapping data of EBSD.
The Cube-oriented sheets were cold-rolled by various reductions in thickness, and the orientation of the cold-rolled sheets was investigated by FE-SEM EBSD analysis.

A large amount of historical data under the corresponding measurement conditions is required for network training before the data correction.
The data correction process is illustrated in Figure 1.
During the data correction conducted at the monitoring station unit, whether or not the data are properly prepared should be judged first because the stable system is a prerequisite for data correction.
The monitoring data sets include flow velocity of cross-section perpendicular at different points, totaling five data by one propeller flow velocity meter sensor.
The neutral network data correction process Figure 2.

The preset values are used in level-1 control equipment (Switching over timing of preset values are determined by level-1 control equipment), including centering preset data, coil car preset data, POR (pay off reels) preset data, welding condition, entry loop tension, mill ASD preset data, sleeve preset data, inspection preset data, weight preset data, and band preset data.
In this calculation, reduction schedule is not be changed for other stands.
Secondly, storing actual data into setup data table is finished.
The received data (TCM actual data) are stored into SMLDT of the coil that exists under last WPD before mills.
And then the calculation of adaptive coefficient and feeding data back can be achieved by given actual data.

The scenarios are generated using the forecasted data, mean and standard deviation of the forecast error at every time stage and lie within a certain known probabilistic confidence interval.
The sampling of random processes results in scenarios, which represent the future realizations of the uncertainties and are generated using the forecast data, mean and standard deviation of the forecast error which cover the 90% probabilistic confidence interval.
Assume that S denotes the scenarios in the initial set with a probability distribution P, denotes dimensional stochastic data process with parameter set .
The optimal choice of J for scenario reduction is given by the solution of the optimal reduction problem: (3) Two main algorithms are mainly used in scenario reduction: backward reduction algorithm and forward selection algorithm [6].
The numbers of step of shift operator is decided between several numerical data based on a certain probability.

A simplified expression , (2) is often used for the interpretation of experimental data.
The symmetry reduction caused by the periodic modulation/twinning of tetragonal lattice in nano- or mesoscale was ignored in the Refs. [5–8, 10, 13, 14, 17–24] and the equation (2) was used for the interpretation of experimental data obtained for the 5M martensite.
