Introduction In the backdrop of the world's energy crisis, automobile fuel economy has been increasingly attracting people's attention, and aerodynamic drag reduction will effectively reduce the fuel consumption.
The technology of CFD can simulate the conditions and obtain the data which experiments cannot [2].
Latin hypercube sampling (LHS) is a method of variance reduction which has been widely used in the fields of simulation, optimization calculations and reliability calculations [3].
Seen from the analysis of streamline distribution diagrams of the models, a smaller CD will be acquired by the backward movement of boundary layer separation points and the reduction of vortex area.
Considering aerodynamic characteristics, some measures can be taken to move vortex area backward or reduce the area of vortex in automobile style design for the purpose of aerodynamic drag reduction.

According to the r-factor, SENSE causes the data collecting time to reduce and speed up.[11][12].
The reduction in SNR is caused by two factors, the first is the reduction in sampling time.
SNR Value Difference Test for MRI Phantom T2WI TSE SENSE with R factor 2 Between Before and After Denoising Non Local Means (NLM) Technique SNR p value r2 pre * r2 post < 0,001 where r2 pre indicates r factors 2 before denoising NLM r2 post shows r factor 2 after denoising NLM and * indicates the comparison SNR Data Fig 5.
This study used data from two R factor trials.

There are some data about properties of the isomorphic series in the literature [3, 4].
The first discharge-charge data indicated the batterie with Cu2SO3·CuSO3·2H2O as working electrode had poor cycle reversible, and subsequent charge-discharge profiles had no obvious platform.
The two reduction peaks at 1.4 and 1.2 V correspond to the reduction process of Cu2+→Cu+ and Cu+→ Cu, respectively.
The 1.2 V reduction peak is stronger due to double Cu+ change to Cu.
The middle reduction peak between 1.0 and 0.02 V correspond to S4+ reduction to S.

Thus, the upper- wedge tool remains stationary and the lower one can move in three senses: vertically-to regulate reduction ratio, in-out way- to provide coaxiality of the tools and lengthway to ensure motion in rolling.
Comparison of simulation and experiment results № Experiment Qform simulation 1 2 3 4 Conclusions Forming and rotation of the plasticine workpiece is exercised similarly to the metal forming process for the percent reduction δ=1,55.
As a result of the experiment with reduction δ =2, typical metal defects (laying, pivot journal occurrence, strong ovality) were not found.
According to simulation data, the highest pressure on the tool for plasticine rolling 2 MP, powered the deformation 46,3 N.
Strain data are substantially smaller than tensile strength of plastic ABS (21 MP according to the results of testing of this plastic on the Instron DX600 tensile- testing machine).

Firstly, the construction procedure should be simulated so as to assure that the theoretical analysis results accord to the design data.
According to the inspection report, geometric cross section area reduction will be carried out in simulation calculation.
According to inspection report, concrete elastic module reduction factor of this bridge is defined as 0.75.
Simulation method of prestressed reinforcement steel bar losses Simulation method for prestressed reinforcement steel bar loss reduction is, in range of 13m longitudinal damaged beam span length, 10% reduction of prestressed steel bars reinforcement area as losses, steel bars reinforcement area is kept on right side.
For the purpose of better mastering bridge actual condition after fire, monitoring and collecting of onsite data is very important, do parameter identification for calculation parameters, create finite elements model simulation analysis, determine actual working status.

Fungi will be selected and isolated using the established available method and data based on previous studies. 2.2 Airborne fungi and bacteria measurement Airborne fungi and bacteria samples were collected using the BioStage® single-stage viable cascade impactor attached to a SKC QuickTake® 30 Sample Pump with Malt Extract Agar plates (MEA) at a flow rate of 28.3 L/min as per requirement of National Institute of Occupational Safety and Health (NIOSH) by NIOSH Manual Analytical Standard Method (NMAM 0800).
The graph for percentage reduction of fungal growth is illustrated in Figure 3.

Thick wallpaper gave the highest percentage reduction of fungal growth as compared to the other three types of wall finishings used which was 60%.
The lowest percentage reduction value is seen in thin wallpaper which was only 10%.

Analysis on Strength Reduction Coefficient Strength reduction coefficient is the ratio of the residual bearing capacity of the compressive brace to buckling bearing capacity after the brace buckling in compression.
The strength reduction coefficients are average.
The relation curves between the reduction coefficients and the different slenderness ratios are shown in Fig. 5.
A new strength reduction formula of the compressive brace is proposed based on these data at 0.5%, 1%, 1.5% and 2% story drift level.
Strength reduction coefficient of the compressive braces curve At the same story drift ratio, the reduction factor increases with the increasing of the brace slenderness ratio.

The theory and experiment data are contributed to the VLSI circuit design in the future.
With the reduction of the thickness of gate oxide layer, the gate tunneling current increases by three orders of magnitude from 10-9(A) to 10-6(A).
Fig. 2.1~2.2 highlights that the gate tunneling current increase with the reduction of the thickness of gate oxide layer.

In both cases a calibration procedure based on hardness data was involved.
Input data for these models were established by involving a calibration procedure based on hardness data.
If some parameters as Qd and Qs energy terms can be found or calculated from literature data, the others parameters of JMAK model and Myhr and Grong model need to be calibrated against experimental data.
The hardness data were then converted to X using Eq. 1 with HVmin = 78 and HVmax = 155.
One can notice that some of the data were not well fitted by the master curve.

These in turn can read and control all production data in electronic form; data from actual production time appointed by employees, inventory costs, demand forecasts, working hours and other data related to production.
There are in the market software that read the data from the production up to the accounting data, but the connection and interpretation of these data usually do not show a direct link.
Thus, resulting in assumptions in information handling and possible flaws in the evaluation of the data that exist and are available, but in a disorganized way.
