Those data consist of measurement and nominal data as quantitative facts and are supplemented by expert knowledge as rather soft facts to be describes by fuzzy input variables.
Acquisition of Measurement and Nominal data The results of current and power measurement are defined as measurement data.
This allows creating the required data base on factory level and increases transparency.
Considering all sources of data being illustrated in Fig. 2 first the quantitative input data need to be acquired: Those data like the runtime are typically gathered from the production schedule out of the ERP-, MES- or MDE-software.
Figure 2: Sources for input data [11] Additional to the quantitative plant data expert knowledge concerning all machines have to be collected.

Weight loss data are acquired by computer automatically.
As is shown in figure 3, weight loss rate curve can be drawn in this time stage according to weight loss data and equation (1).
By using temperature-rising and weight loss curves of Fe2O3 powder containing activated carbon in condition of reduction roasting, 40 kinetic mechanism functions and the corresponding data are substituted into equation (7).A diagram of vs was fitted by the least squares fitting .The reaction kinetic mechanism was determined according to the fitting correlation coefficient, so that reaction controlling steps in different temperature periods could be determined.
Then promote the reduction roasting reaction “overall activation”, and that can reduce the reduction roasting reaction temperature.

They may use Hive, Pig, ZooKeeper, Cascading and other module to solve serious problems in TB/PB magnitude data storage, extensible computing, and data analysis processing, and so on.
Experiment proved that when the data volume increases, the memory overflow of MR_CD and MR_DD will occur.
As to the above deficit, scientific reference [6] and reference [7] have made equivalent improvement, the idea is to add in a Combiner prior to Map output, used to reduce the local data reduction, similar to the local Reduce function, reducing data transmission in the network and I/O reading in the disk.
Map scans every recorded sectional K candidate item sets in data subgroups, each candidate item set counted as 1, then output the intermediate result by Combiner reduction.
Then we will use the present existing TB/PB grade gigantic data sets to undertake simulated test to this algorithm.

According to the data presented in Table 1, in the near infrared region bismuth in some glass systems may have a broadband luminescence with a full width at half maximum (FWHM) of the order of 250-300 nm at 1.3 microns position.
Therefore, the reduction conditions are needed.
The absorption spectra of samples treated at reduction conditions were also measured.
Those data are in accordance to literature data and the measured Bi near infrared luminescence under 455 nm excitation is shown [2, 3].
Taking into account the data, we can conclude that the luminescence centers have the same nature.

The EUROCONTROL study found a benefit of 1.6 to 2.3 percent reduction in fuel burn, and 0.7 to 1.0 percent reduction in emissions of nitrogen oxides (NOx) as a result of implementing RVSM.
To this end a large body of computerized flight data recorder [7] (CFDR) data was obtained for a variety of commercial aircraft.
Available CFDR Data Aircraft Type Engine Type A320-214 CFM56-5B4-2 B757-200 RB211-535C B767-300 CF6-80C2 ARJ85 LF 507-1F The CFDR data were quite extensive in the breadth of variables contained, with 103 directly measured or derived values.
This accuracy was previously found to be within ±14% of corresponding NASA data with 1σ confidence [8].

Introducing geodesic distance to replace the original European distance data will make twenty-four dimensional data, which using the traditional MFCC feature extraction down to ten dimensional data.
This paper put the Manifold learning used in speech recognition of the feature extraction, proposes a new MFCC - Manifold feature extraction method, to the low dimensionality reduction is effect, and the characteristic value of the data quantity have done a lot about minus.
Realize the data dimension reduction or about data visualization and obtain appropriate mapping relation.
For convenience of shows that the characteristic value data quantity about loss of direct effect to MFCC feature extraction of characteristic value data quantity as the standard, the type definition: Data ratio = (MFCC - Manifold characteristic value data quantity) / (Mel characteristic value data quantity) TABLE I.
Can be seen from table 1, compared with the traditional MFCC its final recognition rate has, and the data reduction about is above 70%.

The dynamometer controller also records data such as the engine speed, torque, power, engine temperatures, throttle pedal position, fuel flow and air flow in real time.
Prior to running the engine for data collection, the engine was warmed up for 20 minutes at 2000rpm and 20% load.
The engine was allowed to stabilize before the data were recorded.
Data for other speeds and loads also showed either slight increase in NOx emissions or no significant change.
Reduction of up to 56% was observed at 40% biodiesel fraction.

So the dense asphalt-rubber pavement was the most common one for noise reduction, which was paved by gap-graded, macro-texture, dense asphalt concrete, belonging to the types of elastic and optimized surface texture noise reduction pavement.
It could provide reference for designing, constructing, maintaining and evaluating the noise reduction asphalt pavement.
Beijing Municipal Science & Technology Commission had spent RMB 2 million to study the technology of designing, constructing, maintaining and evaluating the noise reduction asphalt pavement in 2007.
And developed a new noise reduction asphalt pavement, which was paved by gap graded, macrotexture, dense asphalt-rubber mixture, It had invented a trailer with weight to measure tire-pavement noise in accordance with close-proximity method-proposed in ISO/CD 11819-2:2000. [2] The preliminary findings presented here are analysis of tire-pavement noise spectrum of noise reduction dense asphalt-rubber pavement.
Data processing method: it fits dynamic modulus testing results into master curve with reference temperature of 20℃ on the basis of time-temperature equivalence principle of asphalt mixture.

With the obtained data the Hollomon curve as well as the Hall-Petch constants were obtained and the results were correlated with the corrosion resistance of the anodes.
With the data of the yield stresses and the effective strain of the samples (εeff = 1.15·ln (12/final thickness), the Hollomon curve corresponding to the anodes was determined.
Micrographs of the anodes a) current. b) with 75% of cold reduction.
Note that anodes with 75% of cold rolling reduction have very small grain size.
Conclusions The yield stress of the anodes can increase from the current value of 58 MPa, obtained with a cold rolling reduction of 50%, to 64 MPa reached with a cold rolling reduction of 70%.

The results demonstrated when the slope stability in the seasonal frozen regions was analyzed using shear strength reduction method, the two deterioration modals can provide the data reference for the analysis.
So study on the damage degree of shear strength parameters of c and φ, which can provide data reference for slope stability analysis.
