The experimental data have been discussed and analyzed by comparison with theoretical results.
Table 1 – Experimental data of RC beam model.
Considering the Figure 4 it is possible recognize a reduction of values increasing the damage from D0 to D3 with a maximum value of about 57% for the first mode of vibration.
The reduction of frequency values has been recorded in particular for the first mode while for the other modes of vibration the reduction is lower and equal to about 20%.

The predicted results are good in consistent with the experimental data.
The damping loss factor (DLF) can be calculated by using the formula of theory and experiences or by processing the test data.
It shows that the deviation between the measurement and simulation data using FE-SEA model in 200-1000Hz (excluding 1000Hz) is 1.7dB, which is smaller than SEA model.
The reduction 0.8354dB is better than the one in 1000-5000Hz 0.1736dB.
The weight reduction is 15.34 kg after using interlayer PMMA rather than the glass.

It provides more jobs and meanwhile achieves the energy reduction as well as reduction of time, effort and money.
Data shows that the energy consumption ratio of e-commerce is 1:8 with the same GDP production when compared with traditional business.
Data from Ereli market survey indicates that online recruitment users make up 18.8% of all internet users.
Flex provides a modern, standards-based language designed to support the public module, the client operating environment, development model and advanced data services.
In database design, analysis of data structure, data flow and data storage of data dictionary is need. it extracted the data according to data diagrams, determined the entities, entity attributes and relationships between entities, obtained the relationship model of the system.

Powdered chicken feathers–PCF (4% w/v) were added to the medium due its nutritional properties, its potential to be used as a solid supporting material to optimize bacterial growth (data not published) and also due to its previously reported arsenic biosorptive capacity [3].
The same feature was observed in this study (data not shown).
It was observed that the deleterious effects on bacterial growth caused by As(III) are less severe for those experimental flasks containing PCF (data not shown).

The in-situ electrical resistance data recorded in the isothermal annealing process show the same relaxation behavior with fitting parameters 0.0362, 2033 s, and 0.74, respectively.
The fitting parameters of the experiment data with Eq.1 are 0.0384, 2390 s and 0.66, respectively (as shown in Fig.4).
Compared with the discrete electrical resistance relaxation experiment above, the in-situ electrical resistance relaxation data show almost the same tendency and values.
The solid line denotes the in-situ electrical resistance data, the dash line denotes the KWW fitting curve, the solid squares (■) denote the data from the discrete electrical resistance relaxation experiment, and the open circles (o) denote the recovery enthalpy in DSC scans [7].
Fig. 6 Relaxation time constant versus annealing temperature plot of La55Al25Ni10Cu10 bulk metallic glass, the relaxation time is obtained from the KWW fitting of the electrical resistance relaxation experiment (■) and DSC data from reference (o) [7].

The part injected ethanol and direct injected diesel were tested in various proportions, to optimize the operating range, and the same setup was tested with various % of EGR.The obtained results include data plots illustrating the performance, combustion and emission characteristics.
It can be observed that the rate of heat release in the premixed combustion zone decreases with higher premixed ratios, which may be the reason for NOx reduction.
The combustion in the diffusion combustion zone diminished when the premixed ratio increases, which might be the cause for the reduction in the smoke intensity and NOx reduction compared to base diesel.
There was about 52 % reduction in the NOx emission while using 20% premixed ratio at full load.
Nearly 52% reduction in NOx emissions was achieved with 20% of ethanol as premixed fuel. 86 % reduction in NOx was achieved at 75% load and 20% EGR

Thus a study using more recent data to analyze the energy consumption and major environmental emissions in urban passenger transport is crucial.
Methodology and Data The LEAP model.
However, the increase speed of total energy consumption have different degrees of reduction in the case of adopting different energy saving and emission reduction measures.
For nitrogen oxide emissions, the emission reduction effect of scenario 2 and 3 are almost the same.
Meanwhile the reduction effect of SO2 emission under scenario 3 is better than that under scenario 2.

The data are acquired spirally at the sampling interval of 1 mm.
Next, by selecting the data which are inside 0.5σ which is the standard deviation of GBIR of the wafer profile, the data which have overlarge GBIR are eliminated.
As a result, the number of used data is 58 data.
Fig. 8 Method for identifying the noise of an actual machine The denoising methods with TV and WT using the combined method are applied on the sample data to study their performance in noise reduction.
Figure 9 shows the distributions of GBIR of (a) raw profile data and two profile data filtered with (b) TV and (c) WT using the combined method.

We extract the normal data to train the detector.
It is regarded as normal behavior which is in the circle and as anomaly behavior if it is beyond this range. ④ Dimensionality Reduction Mapping Data produced by security system in real time should send to the detector after data pre-processing.
All abnormal data detected are converted to RPES coordinate through dimensionality reduction.
Data are KDD99 data set.
The experiments also display normal data in order to contrast with abnormal data.

The input data is given to row column interleaver and m2 columns are encoded using extended Hamming column encoder.
The encoded data is applied to the extended Hamming row decoder for decoding.
The previous row decoded data stored in the buffer is row-column interleaved.
The column parity check bits and row column interleaved data are passed to the second stage column decoding.
