Through the general data packet service [1] transmission method to collect the hydraulic characteristic information can be transmitted to computer, and then faults diagnosis.
The main idea of rough set theory is in the premise of maintaining the same classification ability, through knowledge reduction, decision making or classification to export issues rules and the reduction of which can be used for pre-processing on high-dimensional data to remove redundancy property, so as to achieve the purpose of dimensionality reduction in fault diagnosis, the use of rough set theory to specific monitoring and diagnostic data processing, diagnostic information can reduce redundancy, improve the diagnostic efficiency [2].
Forklift hydraulic system is characterized by relatively large parameters, not all selected; (3) Creating the relevant target data set (the original sample database), in other words, knowledge acquired data samples; (4) Data reduction, including attribute reduction, value reduction; (5) Mixing rule knowledge base generated.
Attribute reduction is equivalent to eliminate some unnecessary ranks from decision-marking table; attribute value reduction is eliminate some unnecessary attribute value from the table.
Decision-making table without any redundant information can be get by the manner of attribute reduction, value reduction, and shown as in table 4 ("*" indicates can not be considered).

Requirements of data exploration methods are much more simple.
The aim of this work is to compare statistics and data mining methods with sensitivity analysis results and verify if we are able to achieve similar results with significant reduction of number of measurements.
Application of data mining The statistics and data mining procedures were applied to estimate the importance of the parameters of the hot rolling of dual phase steel strips.
Reduction of dataset.
The smaller the data set, the faster will be the calculation.

The two-phase CPAL register file consists of a storage-cell array, address decoders, read/write word-line drivers, sense amplifiers, and write bit-line and read data-line drivers, as shown in Fig. 3 [4].
The write bit-line and read data-line drivers are as much as the number of memory columns.
Because about 70% of memory store data are "0" [5], the storage cell with double-threshold technique can reduce leakage in the inactive state.
Summary This paper focuses on leakage reduction of the register file based on CPAL circuits using DTCMOS schemes.

The WO3 is a stable oxide because the reduction agent used to promote the reduction was not sufficient enough to reduce to zero metal tungsten.
The reduction divided into three stages: the reduction of WO3 to WO2, reduction of WO2 to W and then significant methane decomposition.
For identification purposes of crystalline phase composition, diffraction pattern obtained were matched with standard diffraction data (JCPDS) files.
Results & Discussion Thermodynamic Consideration Data.
The reduction should be preceded by formation of WO2.96 as the earliest reduction of WO3 [3].

The technology of wavelet noise reduction can not only suppress the signal’s noise, but also can overcome the shortcomings of conventional noise reduction methods.
Therefore, wavelet de-noising is a very effective noise reduction method.
By comparing the experimental data, this paper estimated the relationships between regulatory factors and SNR, RMSE are estimated, shown in Fig1 and Fig2.
Experimental procedures. (1) Programming under the CCS environment, and make the DSP reading the vibration test signal data that collected from headstock CA6140
(3) Use MATLAB to process the measured vibration signal for noise reduction

However, the study lacked data on the reduction of complex oxide compounds that may be a part in technogenic raw materials.
At the same time, studies of the reduction of individual oxides in Mo-O-C [21, 22] and W-O-C [25, 26] systems determine the two-stage reduction.
The development of this study is possible in the direction of expanding the range of steel classes, the oxide waste of which will be involved in processing by the method of smelting reduction.The challenges in attempting to expand this research lie in the lack of sufficient experimental data.
