Through reasonable use of these collected data, you can draw floor plans, topographic maps, ortho photo images and so on in details, which can also identify ground targets, the distribution of the growth of facilities and resources.
At present, the GPS measuring the aerial mapping can be divided into four steps pictures, namely select GPS observation are nodded, choose GPS observation time observing the assignments, and processing, GPS measurement data
The Processing and Analysis of Glaciers Image As one of the important data sources of spatial information, remote sensing image acquisition equally becomes mature with the development of science and technology.
It broke through the difficulties of access to data, and is in the direction of the positive full application development.
Generally speaking, the reduction of as latitude, which motivates snowline high, the zonal quite obvious that the latitude.

However, these works were carried out in the “low” range of cutting data with respect to the machinability of the material.
Research work [18,20] shows that the selection of cutting tool should be based on the volume fraction and the nature of the reinforcement in combination with cutting data and machining operation.
The results show that the difference in surface roughness between CO2 and emulsion is almost insignificant over the whole range of cutting data.
A comparison between these two figures shows that CO2 coolant gives higher tool life compared with the conventional emulsion specificly at the high range of cutting data.
According to the results in Fig. 9, the influence of the CO2 coolant on the tool life is very obvious and efficient over the whole range of the cutting data.

Therefore, text data mining became an increasingly popular and important research topic.
Because the existing data mining technology is not mature enough, the current topic automatically extracted technology cannot produce highly accurate and consistent theme.
Text mining is a branch of data mining which is used for knowledge discovery.
Rough set theory proposed by Polish professor Z.Pawlak in 1982[7] is a mathematical tool to analyze data, which is also useful to deal with fuzzy and uncertain knowledge.

In order to integrate the ARM core micro-system whose kernel is uC / COS with NC lathes,uC / COS whose good portability and reduction can be reliably applied to various control systems.
The software developed in the environment of embeded visual C + + includes data’s collection and storage, data’s preprocessing and analysis by which the current value may be online real-time displayed.
The second one is to solve the model parameters with the data- measured method, and the final one is to evaluate the merits and defaults of regression model by comparison of fitting degree between the measured data and the theorical data.
If the data are not well fitted, it is necessary to further recalculate the variable, otherwise the model can be used to predict.
Coefficients a0,a1,a2,a3,a4 can be decided by regression analysis based on data measured.

By carrying out high-level monitoring of the development process through the analysis of pollutants, researching environmental monitoring is to obtain scientific data to guide environmental protection [2].
It is not just the process of determination of the concentration of pollutants, but also includes the process to take on a variety of data of environmental quality measurements.
This process needs to solve, evaluate and analyze the data comprehensively to make sure that the conclusions of environmental quality are accurate and scientific.
Special environmental monitoring in the water and pollution reduction plays an irreplaceable role to make important contributions to environmental protection work [3-4].
With the scientific data to reflect changes in environmental conditions and the law timely and comprehensively, environmental monitoring should be used to improve the quality of the environment as a starting point to meet the needs of modern environmental management direction.

RE08A is a rotary encoder kit which can convert the data of rotary motion into a series of electrical pulses which is read by controller.
Modeling and Design Fig. 4 shows the sequence for data collection procedure, the algorithm for the collaboration of DAQ and Labview.
Angular Speed of the turbine was measured from Equation (5) and (6); the data was taken from the Rotary Encoder Kit sensor (Fig. 3.3) which passed the signal to DAQ (Fig. 3.4).
In order to accomplish this goal, we required a rotary encoder kit (RE08A) and a Data Acquisition device (NI-USB 6212 Driver).
The DAQ device acquired the data and sent it to the computer.

It transmits the information collected by the terminal to station, providing the data source analysis, as well as the fault flow calculation.
It can not only collect sensing terminal data, but also the change of transformer current and voltage.
The information provides data support for the single-phase earth fault detection.
The abnormal one can be switched to the other phase terminal, to ensure the data reporting is accurate and reliable; the terminal reports current communication situation daily and the state tracking data for each terminal node; in order to ensure the resistance to other interference, special processing is used such as detection before sending , frequency switching and other means.
It will provide data for the decision-making and reliable operation of distribution network.

Results Raw data.
It can directly be seen from the raw data that the peaks are positioned at different vertical positions, corresponding to different strains of the scattering entities.
It can be seen that the sharp peaks and the cloud of enhanced intensity observed in the raw data is clearly represented in the projection.
Raw data.
A comprehensive search in the data set obtained while doing additional strain steps, did not reveal such events, instead an unexpected intermittent behavior was found [6].

Section III details our design scheme of congestion control algorithm based on packet loss.Section IV verifies the efficiency of the algorithm through the simulation data.
Therefore, the reduction of congestion control window causes a sharp drop in the network performance.
Resource pooling must also be able to effectively respond to emergency data.
In order to simulate emergency data of link 1 .
Uncoupled TCP algorithms cannot timely move data, and thus the performance is the worst.

Settled were the indoor data from mechanical and physical tests for rock bodies (Song et al, 2004).
Coupled with wave test, got were 91 series of correlative data between ultrasonic wave and rock bodies’ modulus of deformation.
Fig.5 Correlation between E0−Vp Fitted renewedly were 145 series’ data from feasibly studying stage and technologically operative stage (showed in Fig. 5).
All the data distributed concentratively in one banding zone.
