(Fig.1a) shows the relevant data based on data charts,We can see the distribution of a large range of energy efficiency test data, the uneven quality of Chinese product manufacturers, the majority of air-cooled air conditioning energy efficiency of 3.0 or less, significantly lower than that of Europe, Japan.
According to the measured data,we can calculate the SEER with the Eq. 1 ,Eq.2 and Eq.3.
According to Chinese meteorological data, we can find the part of the city's SEER value(see Fig.1b).

The use of hot strip steel instead of part of cold strip steel in making automobile inner board has been considered for cost reduction of materials.
On the one hand, hot strip steel within the thickness of 2.0mm was considered for cost reduction of materials to get cold strip steel.
According to the forming limit diagram at the right side of Fig.6 and Fig.11, nearly all the data was in the safe region, a few elements may remain the residual stress,all the elements can not be in failure.

The inclusion of 60% of cement implies in a reduction in the mechanical properties when compared with the results of the composite manufactured with 40% of cement.
The ANOVA will be validated by Anderson-Darling test which evaluates the normal distribution of the data and Bartlett and Levene tests which verifies the homogeneity of variances between treatments.
The use of 60% of cement implies in the reduction of the mechanical properties.

Figure 2 Simulation Signal Spectrogram Figure 3 Performance Detection of Singular Point in Literature Algorithm(Simulation Signal) Figure 4 Performance Detection of Singular Point in Algorithm in this Text (Simulation Signal) Figure 5 Detection Probability Comparisons of Two Algorithms Figure 6 ROSA Algorithm Estimates the Leading Role between Subspace and Real Subspace Order-1 Subspace Tracing Algorithm under α Stable Distribution Noise Environment Based on the concept of phase fractional lower order moment, the paper proposes order-1 subspace tracing algorithm (PFLOMROSA), namely order-1 update formula of data covariance matrix in the above-mentioned ROSA algorithm is modified as the following order-1 update formula of phase fractional lower order moment: (4) Conduct nonlinear processing on receive data vector x(t), then the modified order-1 update formula of data covariance matrix is:
In other words, first of all, it is conduct nonlinear processing on receive data vector x(t) and order-1 update formula of improved data covariance matrix is: (6) Specific process of improved order-1 subspace tracing algorithm is shown as: 1.
It can know that average evaluated error of ROSA algorithm is significantly increased with the reduction of SNR.
Average evaluated error of PFLOM_ROSA algorithm is also increased with the reduction of SNR.
However, average evaluated errors of SCM_ROSA and IN_ROSA algorithm have no obvious variation with the reduction of SNR.

For the accomplishment of the calculation of conditions of starting in EDM machine, we have implanted a computer science application that besides to make these calculations, it serves for the study and compilation to us to data and provide a support to us for the optimal exhibition of results and fast and easy access to a data base with the values of the different ones own parameters of the machine.
The computer science application is a connection between the programming code and a data base constituted initially by the values provided by the manufacturer.
Screen analytical method This computer science application also contributes to a format standardized for registering the results and specifications showing the information necessary for the correct definition of the organized process being according to following sections: client, data of the problem, setting of the generator, cleaning, data for calculations and results as much for the operation of rough-dressing like for finished the one of, as well as corresponding sketches of the electrodes Process of EDM of the artistic profile in 3D After positioned, the mould and the electrode in EDM machine is come to the accomplishment of the later rough-dressing and finished of the two parts that form the mould used for the validation of the methodology and the procedures.
It has really been implanted procedures methods that allow to contribute the necessary data for development of the process of starting of EDM by penetration and that it presented/displayed of a clear and ordered form without use of manual with tables and graphs.

The results indicated that the strength was maintained up to near solidus temperatures, with no dramatic strength reduction being observed.
The force and displacement data were recorded to calculate the true stress and strain.
The fitted curves including the experimental data are illustrated in Fig. 3.
Note that there was a distinct change in the slope around 720 K with the 7449 data, while no slope change was observed with the 6082 data.
No dramatic reduction in 6082 flow stress curve near the solidus temperature is observed. 2.

Using the UV-Vis absorption spectral data, quantities such as nephelauxetic ratio, bonding parameter and Racah parameters are evaluated.
Both bonding parameter and nephelauxetic ratio revealed a reduction with increasing concentration of Au NPs, where decrease in the ionic bonding between Sm3+ and surrounding ligand have clearly indicated an enhancement in the covalency.
The observed reduction in the nephelauxetic function is attributed to the weakening of the localized d-electrons aroused from overlapping d-orbital and ligand orbital.
UV-Vis absorption spectral data was used to calculate the ligand field parameters such as crystal field strength (Dq), Racah parameters (B and C), and nephelauxetic function (h) which are enlisted in Table 1.

In subsequent machining tests, a reduction in the thermal effusivity b led to an increase in tool life.
The values for the thermal conductivity were interpolated and extrapolated from the data of Tlili et al. based on the coating composition [13].
Since the temperature at the tool surface cannot be derived directly from the measured data due to its unsteady and non-linear course in the tool, a method for determining the mean surface temperature is presented.
In the first step, the rake face temperature is calculated by extrapolation of the temperature measurement data (Fig. 2, right).
In the absence of experimental data on the friction coefficient of the coating system, this aspect was neglected in the context of this work and should therefore be the subject of future work.
