We choose TCP data packet Flag to reflect the microscopic view of data packets' internal field changing.
In order to obviously distinguish data packet forgery with real data packet in Flag, we define different weights to different TCP flag.
Thus in microscopic view, the internal data packet field, data packet IP address and port feature will be changed dramatically.
We call triple (IPs, IPd, PORTd) is the I-I-P feature of TCP/IP data packet.
In the microscopic internal data packet’s attribute field, we extract TCP/IP data packet header flag and import describe I-I-P triple of IP address and change port number.

Measured signals which are measured in time domain signal from three channels input were defined as;
(i) x-axis : data of channel I, axial vibration
(ii) y-axis : data of channel II, vertical vibration
(iii) z-axis : data of channel III, horizontal vibration
This composition process produces three dimensional graphical representations which permits the reduction in dimension.
The coefficient indicates the degree of data scattering with respect to the data centroid.
After the accelerometer and DT9837 were connected, the data collection began.
The collected data were also saved in the computer for subsequent analysis.
All the data obtained in the experiments are shown in Table 2.

The same significant reduction is the groundwater storage, which is 590 million m3 in 2009, 9210 million m3 in the late 1980s and 11280 million m3 in 1960 [5].
The data of each variable of the equation (1) comes from the government statistics.
Then we analyze the qualitative impaction which the decline of Dan, Apr and Asc impact on the containable population, and the data comes from the Beijing Statistical Yearbook.
Each 1% reduction of Apr can increase 14.10 million of the containable population.

However, the property of membrane materials can be decayed with the usage in manufacturing process, such as the change of membrane flux and the reduction of membrane selectivity, which makes the separation effect worse.
In this paper, the conditions for these four types of membrane property decay will be simulated to get the propylene yields as well as other process parameter data under different conditions as shown in Table 1.
As a result, much more gas enters into the permeate gas side across the holes directly without experiencing the process of selective permeating leading to the increase of recycle gas flow in CCM as well as the reduction of membrane selectivity.
Corresponding strategies for different kinds of membrane decays are adopted by analyzing data simulated.

Different substances can all be electron acceptors of the negative electrode, but oxygen is the most appropriate and sustainable. [2] Therefore, one of the key problems of MFC system is to develop high effective oxygen reduction reaction electro-catalyst to increase its electricity output power.
Data analysis.
The polarizing data of electrodes was derived through changing the external resistance (10000-50 Ω).

When a dopant migrate to the surface, the consequent reduction on the surface energy can be predicted by Gibbs [[] Y.
Usually, the XPS technique (X-ray Photoelectron Spectroscopy) is indicate, but it is very expensive and the data is difficult to treat, once the mathematic model to work with heterogeneous composition from surface to bulk is not well adapted yet.
Castro and G.J., Pereira: Cerâmica Vol. 55 (2009), p. 393. ] using XRF (X-ray fluorescence), and the relationship between the quantification data and morphology will be demonstrated in this article.
Probably, this procedure made possible the diffusion of Mg2+ remained into inner dispersion to the surface, since the FRX analysis made after the new thermal treatment always showed a reduction in MgO content, characterizing a redistribution of additive between bulk and surface, with a continuous removing MgO from surface.

Introduction
Based on estimates of the reduction of energy sources, it is of great importance to develop more efficient processes and/or equipment in terms of energy.
The energy efficiency of thermal systems has been one of the main topics of discussion on the preservation of natural resources and the reduction of costs of the processes involved in these systems.
The test rig (Fig. 2a) consisted of a data logger Agilent 34972A LXI, a flowmeter, a heat sink, a computer, three power supplies and a heat pipe heat exchanger (Fig. 2b) composed by five heat pipes with outer diameter of 12.7 mm, length of 500 mm (Fig. 3a).
The uncertainties of the measurements, considering the uncertainties of the data logger, was estimated for the temperature as ± 1.8 ºC and for the heat load as ± 0.28 W.

However, ceria based electrolytes suffer from the partial reduction of Ce4+ to Ce3+ when exposed to low oxygen partial pressures, and this chemical reaction will cause a volume expansion of the lattice which can result mechanical failure of the electrolyte.
However, infiltration method reported in other papers is very complex always including a reduction treatment of NiO and a long-time immersion treatment to remove the nickel phase.
The ionic conductivities of LSGM and LSGM-carbonate at the temperatures from 450 oC to 650 oC are given in Fig. 4, which were obtained by fitting the impedance data.
There is no data point for the LSGM electrolyte below 550 oC, because the test system with LSGM electrolyte acted like an open circuit at the temperature lower than that.

Figure 1 shows the cyclic voltammogram of the electrode in the H2MoO4 + TeO2 mixture solution.The forward scan initially increases linearly and came to a constant at approximately -0.5 V until a sharp current rise at – 0.1 V suggesting a reduction process.
Figure 1: Cyclic voltammogram of MoTe2 Figure 2: Thickness of thin films vs. potentials The current change is associated with the reduction of molybdenum and telluride ions to form solid molybdenum telluride, MoTe2 compound on the substrate.
Thickness cm=Mass gDensity gcm3×Areacm2 (1) The density of MoTe2 film was data gives the value of 7.68 g/cm3 and the area of the substrate is ≈4.5 cm2 (3 cm x 1.5 cm).
The data from UV–Vis-NIR Spectrophotometric measurements revealed that the optical band gap values of the thin films decreased with lowerpotential voltage.
