It is a six degree of freedom (6-DOF) model with linear aerodynamic derivatives determined via empirical data, flight tests and numerical simulation.
The engine and propeller dynamics are simulated in parallel with the manufacturer’s data.
The flight data was recorded and analyzed.
Moreover, the dispersion decreased from 1 g/s to 0.2 g/s, a reduction of 80%.

These data are used to follow phase fractions and mean cell parameters evolutions and stress evolutions in each phase.
Data analysis Global analysis by Rietveld method.
Data have been corrected and reduced (2θ, intensity) patterns using fit2d software [9] (fig. 2).
In order to extract stresses in each phase from these data, we have to determine the 2θ position of one peak in each phase.
Given the amount of data to treat (about 800000 diffraction peaks for the case presented hereafter), we have developed an automatic procedure.

Factors of construction waste’s management Management of Construction waste mainly refers to the construction waste’s reduction, harmless and recycling.
Each parameter to be estimated with the observed data can be obtained only one estimate.
Using AMOS software to analyze the data obtained from the questionnaire, the model’s path coefficients can be obtained, as shown: Fig. 2 Path coefficient of structure equation modeling Table 1 Regression Weights Behavior Behavior Esti- mate S.E.

Data aggregation algorithm removes the redundancy of data each node collects, reduces data transmission quantity and transmits the aggregation results to base station to save energy [4], but it is at the cost of increasing data transmission delay.
Therefore, the cluster head node needs to data aggregation to reduce the amount of network data transmission.
Benefits of establishing data aggregation tree is relatively stable data transmission path, but it requires full integration of data from all child nodes in each parent node.
Data loss exists in the actual network data transmission, retransmission caused by packet loss data, And the more fully aggregated data retransmission, the larger the extra energy.
Though data packet loss rate among nodes is being large with the increase of cluster radius, increases the extra retransmission time, the reduction of Af makes up for its defect, then the total transmission delay is reduced, and ADAUC algorithm saves more than 18% transmission delay than UCFA algorithm, it is better for real-time monitoring.

Instrumentation and Data Measurement This section will described the used of instruments in the experimental engine.
As seem in Figure 2, the use of CNG as a fuel under all engine speed and engine loads depicts the reduction of smoke opacity.
Conversely, the reduction of engine performance is expected causes by the lower calorific value of CNG, improper air-fuel mixture, ignition timing and combustion variations.
However, the low calorific values of the CNG fuel was expected to be the strong influence on reduction engine performances.
This reduction was expected and agreed by the previous literatures.

It is shown that the oxidation-reduction reactions and adsorption processes proceed by the exposed of PED in electroerosive reactors.
Water solutions of organic substances are involved differently in oxidation-reduction reactions and adsorption processes that are defined by the nature of MB, furatsilin and eosin.
Conversion of organic dye at different operation step Operation step of solution MB Furatsilin Eosin conversion of organic dye, [%] PED 38 44 36 Sorption on the iron loading 21 42 64 The post-effect after IED 21 18 - Total conversion 59 86 100 The data in table 2 shows that direct interaction of the PED on organic molecules does not practically depend on properties of organic molecules.
The post-effect of MB is 21% and it is defined by further oxidation-reduction reactions after finishing of PED.
According to paper [3] the coloring of MB changes as a result of oxidation-reduction reactions and it proceeds according to the scheme (1)

Fig.4 The change of two tensile test yield Fig.5 The change of two tensile test tensile strength strength Fig.6 The change of two tensile test elongation Fig.7 The change of two tensile test yield ratio The yield strength and tensile strength of two kinds of steel yield are almost the same under the conditions of almost the same heating time and pressure reduction contrasting 1 with 3.Contrasting the both with 4,we find that yield strength and tensile strength will be increased significantly when the rolling process is reduced, 6 and 7 can also come to the conclusion.Comparing with the same reduction for 4 and 7,we find that the longer the heating time is, the higher the yield strength and tensile strength will be, at the same time, 1, 3 and 6 can also prove this point.
And elongation and tensile strength are concerned, tensile ability is strong, the deformation produce difficultly, low elongation, tensile ability is weak, the deformation produce easily, elongation is on the high side,this data can be reflected.
were cut to 25mm×15mm×10mm cube specimens with abrasive wheel cutting machine.After grinding, polishing and 4% nitric acid alcohol etching the polished surface,and the results using metallographic microscope to observe are shown in Fig. 8.9. 500 times 1000 times Fig.8 Simulation rolling of No.7 sample By metallographic examination, a large number of inclusions are found in 7 mm plate No.7 sample, but the inclusions distribute more uniformly,particles are not very large,generally located at the grain boundaries. banded structure appears in 4mm sheet No.6 sample,and at high magnification(1000times),the shape is slightly different with No.7(presence of the sheet-like martensite, shown in the black stripes similar to the thin line portion). 500 times 1000 times Fig.9 Simulation rolling of No.6 sample Contrasting sample 6 with 7, we can only find the thickness difference in rolling process, namely, the difference of rolling reduction
The high reduction can make the organization more compact, and easily allow higher level of aggregation of element, easily form gathering of inclusions. when there are inclusions in steel, segregation area and inclusion will be band-like distribution along the direction of deformation and form a banded structure when it is cooled.
Conclusions For HG70C, the higher the heating temperature in the hot rolling process is and the smaller the amount of reduction is,the higher the yield strength and tensile strength of the slab will be, when slab reduction quantity is large, there will be generated banded structure containing martensite, water cooling is conducive to the formation of martensite, the formation of the belt-like tissue has certain relationship with the formation of martensite[6],martensite brittleness and poor elongation characteristics will reduce the yield and tensile strength of the slab.

DDNS Server Embedded Data Acquisition Server Monitoring Center 4.
Data Storage Technology In consideration of the security of the data, the system has separated the data processing server, database server and application server from each other and set them up on three independent servers.
In order to ensure the integrity of the data, the data processing server would store the received orchard data into the system cache.
At the same time, the data processor would extract an intact data packet from the system cache for the legitimacy validation according to the preset fixed format.
If it is found in the validation that the received data packet is invalid, this data packet should be discarded.
