Finally, SVM was used to classify the GEP data set.
Neighborhood Rough Setis a method based on classical rough set, it can directly process continuous data [3,4].Therefore, information are not loss before reduction, making the attribute subsets have stronger classification capacity.
RS don’t need any prior information and can only rely on internal information of data themselves to discover tacit knowledge within them, reveal potential rules and effectively process incomplete and inaccurate data.
Neighborhood rough setthat was brought up by Qinghua Hu is a improved method that develops from t classical rough set and can directly process continuous data[3,4].It needn't discretize continuous data in advance, and can be directly used for problems of knowledge reduction etc.
We experimentized in MLLLeukemia data set to vertify our method.

In addition, direct reduction processes, SDR (Sumitomo Dust Reduction) process, SPM (Sumitomo Pre-reduction Method) process, and INMETCO process [2] were employed to treat various types of residues such as sludges and dusts.
Table 1 gives the data of sludges supplied by a Chinese industry.
Table 2 gives the data of EAF dusts supplied by a Chinese steelmaking.

Analysis of absorption coefficient for eco-friendly acoustical absorbers Jun oh YEON1, Kyoung woo KIM1, a 1Building Research Department, Korea Institute of Construction Technology, Goyang-Si, Gyeonggi-Do, Republic of Korea a joyeon@kict.re.kr, b kwmj@kict.re.kr Keywords: Absorbers, Absorption coefficient, Noise reduction coefficient, Eco friendly Abstract.
As a result, the NRC (Noise Reduction Coefficient) was found to be 0.85 for glass wool, 0.95 for rock wool, and 0.70 for polyester, 0.65 for waste absorber, 0.75 for PET+ PP fiber absorber, 0.40 for wood wool board, and 0.75 for foamed aluminum absorber.
In this study, we intend to compare the sound absorption performance of currently used absorbers and eco-friendly building absorbers, providing the basic data for eco-friendly building materials.
It is considered the reduction of the absorption coefficient in 500Hz or more was affected by the size and depth of Aperture on the surface of the waste absorber according to the Helmholtz resonator.

Whilst models of the oxidation kinetics and defect generation are being developed [4,5,6,7], much more experimental data is needed to support understanding.
A reduction in the frequency dispersion is observed with decreasing oxygen flow rate signifying a reduction in the Dit.
The reduction in frequency dispersion signifies a reduction in the interface trap density.
The high Dit in the upper half of the SiC band gap (as compared to Si), has largely been attributed to the generation of electrically active carbon dimer defects near the interface during oxidation.[6, 9] Thus the reduction in Dit may be due to a reduction in the number of carbon dimers.
Thus the increase in EOT and reduction in Dit observed in the present work, may be due to the fewer carbon dimers being formed.

The properties analyzed are based on the data obtained from the steady state profiles from the simulations.
The electronic density of states was obtained from the output data obtained during the simulation.
The average bond length change data as a function of temperature change is not available in literature.
The trend for SiC matches with that by Fahrenholtz et al. [10] It is important to note that SiC data, here, is for the single crystal and Fahrenholtz et al. [10] data is for SiC phase in a composite.
Straining in both cases of SiC and ZrB2 leads to reduction in phonon frequencies relative to 0% strain resulting in reduction of phonon thermal conductance with increase in straining.

Model data agreed well with experimental data.
The preparation methods of (R)-HPBE included resolution of the corresponding racemate [2-4], asymmetric reduction of the prochiral ethyl-2-oxy-4-phenylbutyrate and its derivates [5-9], enzymatic esterification of 2-hydroxy-4-phenylbutanoic acid, and chemical multi-step synthesis [10,11].
Preparation of racemic HPBE. racemic HPBE was prepared by chemical reduction. 1.0095 g ethyl-2-oxo-4-phenylbutyrate dissolved in 30 ml of anhydrous ethyl alcohol was added in 500 ml flask containing 0.054 g NaBH4, 130.0 ml anhydrous ethanol and 8.0 ml distilled water and stirred constantly for 4 h.

The typical noise reduction method include classical discrete wavelet [1] has the fine effect to the stable data but has great deviation to the discrete data.
The sample data can be divided into two parts and keeps the same data as the primary.
Then extract the data to change two lines of data and form odd and even samples
For adapting un-sampled lifting schemes, data reducing was avoided and the data information was kept completely.
The fault data was analyzed with ORSGWT.
