Fractured types are recognized and fractural porosity is calculated by using bilateral logging data.
Then the fractural fractal dimension is calculated by using seismic data to predict the distribution of fractured zone.
To avoid the horizon before unreasonable load layer data model to the fracture system , the application of kriging techniques of data preprocessing [7] , the elimination of outliers , so that faults and horizons to achieve a reasonable match.
The calculation, using known calibration data fitting until the calculated results for the known geological conditions, to predict the unknown before.
Fracture porosity logging data into full play the advantages of high vertical resolution, direct characterization of cracks physical characteristics.

In their investigation, data were presented showing the effect of cold work on the short time creep strengths of various types of commercial copper under several conditions.
This material is submitted to successive reduction by cold wiredrawing process from ε = 14.24 to 92 %.
The strain-time readings were continuously recorded by PC-based data acquisition system.
Each datum of the hardness was the average of five repeated measured hardness and the test load is 100 g.
The structure of drawn-wire after a series of section reduction, is characterized by a regular orientation of the grains along longitudinal section « texture » ( Fig.1a).

The product design 3D model contains not only the geometrical data of product, but may contain a part of the process plan and technological data as well.
The target is to gain experience in these fields at the level of a manufacturing system as a unit. [8] The whole FMS (all manufacturing and handling devices) must therefore contain a communication structure based on modern industrial standard that is compatible also with other industrial facilities to enable trouble free data transfer.
In this reason, we have now activity about a material flow data collection.
One from the visual method for data collection are described at [11] Advantage of this method is a very fast (real time) data collection without a construction modification in the manufacturing system.

Review of published toughness data for N06022 material provided information similar to that shown in Table 1.
Therefore, a normalization of general applicability is needed to formulate correlations to relate subsize data to conventional full size data.
This model works very well and yields miniature specimen Upper Shelf Energy (USE) data within 1 J of conventional data.
This model fits the data very well as shown in Fig. 1 up to 8 mm, and then varies linearly beyond that thickness.

Fig. 3 demonstrates the impact device manufactured by Buerl & Kjear, whilst the data analyser used in this study is the WinMLS program.
The accelerometer was connected to the data acquisition system that was connected to a computer, which was used to transform the time domain to the frequency domain using the stated software.

This model can got high prediction accuracy in short-term prediction with less raw data and not more calculation steps[8,9].
In this paper, Equal-dimensional new information grey model is proposed which based on the rule of metabolism, the oldest data will be replaced by the new generated data as the input for the model to keep the equal dimensions .This method can get a good balance between the precision and complexity of the model and be well used in meeting with the requirement of real-time control.
However the flow data in diesel nozzle grinding is not very smooth.
The method is as follows: First, assuming the original data as Q=(q(1),q(2),… ,q(n)) , Where, if q (k)< l,add a proper constant to each data of the sequence to let q (k)>1 and the constant should be substracted after reduction.
After that, predict the flow by traditional GM(1,1) model and improved GM(1,1) model respectively based on this data sequence, the prediction data curves and the actural data curves are shown as Fig.3 (a) Improved GM(1,1)prediction (b) Traditional GM(1,1) prediction Fig. 3 Comparision of predict data curve and actural data curve According to Fig.3, the fitting effect of Improved GM(1,1)model is much better than traditional GM(1,1) model ,esperically for the Steep transision domain.

Reduction of labor costs with an increase in the reliability of information about the state of damage and technical condition is an actual scientific and practical task.
The response of the structures to the vibrational load can be measured and used to assess the state of the structure based on the dynamic characteristics extracted from the measurement data.
First mode shape of construction with a defect and corresponding value of natural frequency Modeling and analysis of parameters in ANSYS are calculated to simulate the acquisition of measurement data from accelerometer sensors mounted on a physical system (construction) on a small number of points.

Data Acquisition and 3D Knee model The age and gender of the subjects were according to the availability of MRI for research at the hospital repository.
The difference in subject-specific data such as anatomy and the size of the joint could also be the reason for the difference in the above result.
Also, it was found that the contact region between FC and LTC increases with a reduction in the contact region between LM and LTC.
The reduction in CA after 50% partial meniscectomy in an experimental study by Lee et al. [43] was 20%.
It could be observed that the reduction in CA (Table 11) after SM (66% meniscectomy) obtained in the present study (17.6±4.6%) agrees with that of Lee et al. [43].
