The comparative estimation of the runtime reduction in the second stage of CWT calculation is deduced.
This calculations must be repeated with each new data packet, because a delay in the calculation leads to detection delay enemy boats that in the event of hostilities could have disastrous.
Then we can reduce volume of calculations in the second stage CWT when, e.g., solving the problem of detecting and calculating the CWT that must be repeated with each new data packet.
Dividing (9) by (8) we get the comparative estimation of the computation time reduction C in the second stage of CWT calculation:
Gain in computation time increases with the number of samples of the input signal N in the treated data packet.

For example, field instruments for environment monitoring can give the environment monitoring center and sub center with real time data of the regional surface water or atmosphere or waste water or waste gas or noise.
At the same time, the environment monitoring system can reflect and judge the variables of environmental factors by integrating the data given by the field instruments.
At present, the measurement infrastructure of emission in China is weak, so the environmental department can hardly get the real data of emission of enterprises, and also can hardly track and verify the emissions trading among enterprises The third allocation process is the restructuring of pollution right.
The ultimate goal of emissions trading is the reduction and control of pollution.
For the realization of ultimate goals of emissions trading, we hold forth some measurements for the government and other organizations involved in emissions trading: First, governments at all levels should encourage companies with advanced technology of emissions control or with heavy task of emissions reduction to set up joint emission treatment plants in industrial development zone or industrial function zone or in city and town, with the emissions reduction result verified to be held by funders and technical side, and they can use it to offset their emissions reduction quota or trade in the market.

Furthermore, for this welding travel speed (200 mm/min), taken overall (Fig. 2(d)), the data suggests that there is a small increase in particle size when averaged over the whole PZ with tool RPM.
This data is presented in Fig. 2(c).
This data is summarized in Fig. 3(a), which gives the standard deviation of the cell area distributions across the process zone.
From this data it is clear that, as well as the average particle size increasing, the degree of clustering, or inhomogeneity in spatial distribution also rises across the PZ from the advancing to the retreating side.
However, this behaviour is less pronounced when a higher rotation speed is used and the particle's spacing becomes more homogeneous across the processed zone, resulting in a reduced gradient in the data in Fig. 3(a).

According to analysis of the above experimental data, if different operating voltages are used in different stages of water treatment, both effective water treatment and energy saving can be realized and rusting of the water treatment system can be significantly reduced.
In the signal acquisition module, under control of the SCM, sampled signals are conditioned by circuits such as the bleeder circuit, the follower circuit and the amplifier circuit and then sent to the ADC on MPS430F169 so that relevant data can be displayed on the LCD in real time and transmitted to the host computer for data storage, analysis, processing, etc.
As shown in Fig.6, Start of ADC, display of relevant data on the LCD and transmission of serial data are all executed in the interrupt program.
For easy observation of the experimental phenomena and analysis of the experimental data, a host computer GUI in Labview program is designed.
The system displays information such as the operating voltage and the operating current on the LCD and transmits relevant data to the host computer for data storage and subsequent analysis and processing.

(6) The coefficient is dependent on the neutron fluence, and can be determined by calibration using experimental data for surveillance specimens at fixed values of and .
Figure 2 clearly demonstrates that along with radiation hardening, the radiation-induced reduction in the level of brittle strength has a significant effect on the magnitude of the limiting fluence.
According to the data given, neglect of this effect, as it is done in many works, leads to incorrect values of the maximum permissible fluence (m-2).
In contrast, the reduction in brittle strength is associated with an increase in the number of crack nuclei generated in irradiated metal during the local yielding ahead of a macrocrack/notch.
According to the results obtained, along with radiation hardening, the radiation-induced reduction in the level of brittle strength, , has a significant effect on the service life of RPV steel.

This paper uses the Southern east Asia port container terminal as case study and collect data from that.
The ships berthing operation of the port container terminal was simulated and make a model based on true data.
For ships inter arrival time also the data collected from container terminal management and get the distribution with ARENA analyzer.
This model build based on the real data which is given from a port container terminal located at southern east Asia.

The research presents the results of data analysis on degassing of wheel grades of steels in a tank degasser with a capacity of 120 tons, operated at the JSC “Ural Steel”.
The Purpose and Object of the Study The study of the laws of degassing of wheel steel grades was carried out on the basis of the production data on the results of vacuum metal treatment at the installation vacuum tank degasser (VTD) SIEMENS-VAI with a capacity of 120 tons, operated since 2012 in an electric steel shop of the JSC “Ural Steel”.
The Basic Data To study the patterns of steel degassing at the VTD, an analysis of the production data on the smelting of wheel steel grades for November-December 2019 was carried out.
The averaged data on process parameters and the results of steel degassing of the studied steels are given in Table 1.
Therefore, for further processing from the initial production data, the dropouts of melting was screened with a freeboard value of more than 600 mm, and the influence of the slag layer thickness, visually estimated, was not taken into account.

The Situation of study area and Data source Dalian city Situation.
Data source.
In this paper, basic geography data derives from the Chinese academy of sciences institute of 1:100000 Dalian national land use database, including two periods of Dalian land use data from 1990 to 2010.
Due to errors of the remote sensing data interpretation, much amending work were in need.
In the support of ARCGIS9.3 software, two periods of land use vector data were rectified.

The reasons attributed to such drawbacks are the involvement of microbial catalysts for the bio-reduction reaction.
As shown in Figure 2, the absorbance band of MO at 500 nm can be ascribed to its azo bond; meanwhile, the band at 247 nm was possibly ascribed to sulfanilic acid, in line with the data reported [10].
Based on the data collected from UV-vis and HPLC-MS, it can be concluded that MO have been completely reduced to colorless amines in the cathode of an MFC.
Figure 3 shows the effect of a variation of pH on electrochemical reduction of MO.
Because protons should be involved in the reductive reaction, the increase in the concentration of protons would enhance the reduction of azo dyes.

As the decomposition level increases, the frequency division is getting smaller, but the amount of data constant decrease, time-domain resolution is on the decline.
Noise Reduction of the Failure Engine Audio Signal by Wavelet Packet The Denoising with wavelet packet is very similar to the idea of wavelet.
Figure 1 is the audio signal of a temperature sensor damaged, and noise reduction using wavelet packet transform of the four layers with db5 wavelet function, noise reduction as shown below: Figure.1 Effects of Wavelet packet Noise Reduction The noise reduction using Wavelet packet decomposition method is effective, which analyzes signal in detail through the high-frequency and low frequency, to restore and retain the useful signal part, played a good noise reduction effect.
