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.

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.

The higher the pressure ratio of the compressor, the greater the reduction in the overall thermal efficiency of the turbine.
In order to estimate the parameters in the PH model it is necessary to have the historical data collected under the given operating conditions.
The data consist of aging times, feature sample paths and indicators of events (failure(on-line washing) v.s. censored).
Then the likelihood function of the collected data is given by: where is the number of offline washing , is the number of surviving and offline washing, the offline washing time of the ith unit.
The historical data including 160 on-line washing records from 2000 to 2004 are used to establish a PH model to estimate the RUL of compressor.

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.

Based on the obtained experimental data the software automatically calculated the value of specific surface area of the sample by BET method.
Mie Scattering Theory is used to determine the quantity of particles of that diameter which will produce the measured reduction in beam intensity.
Experimental data of particle size distribution in ethanol suspensions correspond with the microscopy data

Background of Case Study In the elaboration and foundation of case study are necessary defining the particularities regarding the entrance data about the energy request and consumer’s placement, the characteristics of energetic conversion systems, the optimization criteria for system’s configuration, control strategies regarding function of energy generation system and particular financial data to the studied hypothesis.
For the building analyzed was calculated the total energy load at 6759 kWh/year [2], situated in Cluj-Napoca, placement with an availability of primary sources of solar and wind energy according to the official data and professional literature [3,4].
As a general input data set to be allowed to use in parallel a maximum of 30 for PV and a maximum of 2 for TE and was also imposed a maximum of 1% as restriction regarding the maximum permissible load on the percentage annual uncovered.
Fig. 3 Percentage costs of energetic system The generation, stocking and conversion technology of hydrogen is in a continuous development, and as they will be validated the researches visualize a reduction of costs, and these types of equipments and technologies will be competitive in the close future to other technologies from the production and energy stocking domain.
