Consider N data samples {(xi,ti)},…,(xN,tN)} where xi is an element of Rn and ti is an element of Rm.
Now, using the same data, the surface roughness of AISI 1045 was predicted using ELM.
Therefore in this case study, we compared the result from ELM and spider SVM using the same data set.
ELM reduces the number of tunable parameters and time of training the data.
ELM is the fastest prediction model with average of 0.20 seconds per sample data.

The typical slot segment monitoring data is shown in Table 1, the maximum drilling depth of the holes in all monitoring groove segmentsare more than 120m.
Though the analysis of the monitoring data, the pipe drawn force under different time of pipe drawn and different hole deviation has been given by the field monitoring.
The factors which have an influence on the pipe drawn force are so many that the discreteness of actual monitoring data is great.
In this engineering practice, 30 sets of pipe drawn force data in different time have been collected, as shown in Fig. 2.
These data conform the numerical simulation of which the result is 840t and 1060t very well.

Data processing module provides PWM duty ratio counts for DAC controller.
We use inner ROM of FPGA to build DAC data sheet.
Data processing module is the core part of the whole system.
A difference between maximum data and minimum data is calculated in a group of data at first time.
And if the difference is in normal range, we should compute the mean value of the group of data and get the current output voltage data.

Although the different images have different three-dimensional data types, the data connection and the spatial distribution, the process of extracting three-dimensional data from the image reconstruction is basically the same.
The second step is the refining and processing of data.
Generally, for the raw data, proper selection and deletion is needed to reduce the amount of data in the reconstruction process.
This method considers the voxel in data field as a translucent material, and gives it some color and opacity to simulate the value of each sampling point and the gradient of sampling point in the volume data, and so on.
Then we assorted volume data to ascertain the transform function of each type voxel color and opacity.

Especially with the continuous increase of production quantity and production time, some oil wells in our country are in a state of reduction or stop production and therefore have conducted a large number of hydraulic fracturing tests and accumulated a large number of accurate production data.
If we don't preprocess the data of fracture pressure, the data might lose authenticity.
Examples and analysis of results Use the data of 25 producing wells in a certain oil field as the input data to train the BP artificial neutral network.
A part of the input data is listed in the following table.
A PART OF DATA OF PRODUCING WELLS.

Exposure time per dataset was 15 min and the CCD-detector was used for automated data acquisition.
A fit of the data from 1 to 39 hours with a diffusion limited precipitation model [7] results in the solid curve shown in Fig.4.
The model function represents the data well up to 33 hours, i.e. to the end of the first holding step.
Such behavior is found qualitatively in our data.

Parameter calculation Through the first step estimation, a series of data is got as shown in table 2 and simulation analysis is carried out based on these data.
For comparison, the oxygen index of above 10 combinations is represented visually by line graph in Fig 2 Figure 2 The content of LOI changes with OMMT The data in table 2 indicates that Flame-retardant effect of the compost depends on its average density, expansion of carbon layer thickness, thermal activity and specific heat.For the thermal activity , the smaller the value is ,the more difficult the temperature in the material passes, the so flame retardant effect is better.

This can be explained from the in linear change of temperature field, the trend gradually slowing and reduction of the slope.
Comprehensive above analysis , although analog data has changed little, it has the vital signifycance.Because many methods come from the experience of other material and some error estim- ation exists ,but it is proved that the simulation data is generally consistent with experimental data in this paper.

Grid areas are mainly distributed supercomputing has distributed instrumentation systems, data-intensive computing and remote immersion four class.
In the OGSA framework, will be all abstracted as services, including computer programs, data, equipment, and which is conducive to a unified standard interface through management and use of the grid.
Grid service completed by defining interfaces to different functions, service data is the information on the Grid service instance, the grid services can be simply expressed as a "grid service = interface / behavior + service data."
In short, the grid service = interface / behavior + service data.
The toolkit addresses security, information discovery, resource management, data management, communications, and error monitoring and portable and so on.

The comparison of the calculation results was made with the help of the data reported in the literature about the phase diagrams of binary systems.
The using of the considered options parametric components for the description of the Si–C doesn’t allow obtaining the diagram, which will quantitatively correspond to the data [5].
But they help to get results similar to the results of the research data [6].
The phase diagram, which is calculated with the using of FSstel data for the Mn–Si system, corresponds to the data of work [8] and in comparison with the reference data [9] is simplified.
The data that should be used in further calculations in the course of these searches wasn’t found out.
