Test Data Processing and Analysis To verify the performance of the propose method in this paper for impulsive noise, GPS measurement data in an aircraft test is used to process.
The time domain wave of the data is shown in Fig.3.
From Fig.3 can see the data is interfered with impulsive noise.
Fig.3 The measurement data Fig.4 De-noising by SVD combined with WNN From the data processing result, it can see that, the de-noising by SVD combined with wavelet neural network (WNN) can eliminate the impulsive in the measurement data effectively.
For the GPS measurement data processing, this method is effective to obtain satisfaction results.

From UV-Vis spectroscopy we observe that the absorbance of rGO decreased as increasing the reduction temperature because the higher reduction temperature yields a high degree of rGO defect.
One of the molecules that can be used as reduction agent is hydrazine [12], in which the temperature FOR the reduction takes place is becoming one of the important parameters to obtain reduced graphene oxide with high quality.
By using UV-Vis absorbances data, we could calculate optical constant (refractive index real and imaginary part) of rGO by using a number of Maxwell equation and Kramers-Kronig relation.
Then we have compared the calculation result with other data which have done by other people with other methods.
Increasing the reduction temperature will decrease the CO bonding in rGO plane [15].

This overview outlines the reduction of quantitative texture data for the use in industrial settings.
Three different levels of data reduction applied in the daily operations will be discussed.
With such data at hand it is possible to assess the performance of a product in a customer process for example involving plastic deformation.
For process control at the pilot or plant scale quantitative texture data either need further reduction to enable texture analysis as a useful tool at the operator level.
An important aspect frequently overlooked when comparing mechanical properties to texture data are through-thickness texture gradients.

The conclusions provide theoretical reference for the further study of aerodynamic drag reduction of complex underground.
In this paper, studies are focused on a real SUV vehicle model, and the drag reduction research on complex underbody was conducted to provide certain theoretical reference to the research on SUV drag reduction.
Firstly, point cloud data of the model were achieved with ATOS scanning and then reverse processed to obtain the full-scale geometric model, which is shown in Figure 1 and figure 2.
The difference between an average of the seven sets of test data and calculation results was only 1.1%, which verified the accuracy of numerical simulation results.
Flow rate increasing and lift force reducing led to the reduction of the induced drag caused by lift force, which was the root cause of the reduce of aerodynamic drag.

This sink node comprehensively checks and compares data and also ensure its secure transmission of data.
While in sensor network, as an important part of the network energy consumption, the way communication reduction how to reduce redundant data and reduce the transmission energy consumption and of research today in the scientific community has become one hot spot in the course of data transmission.
The main purpose of data aggregation is to reduce redundant data transmission and guarantee data transmission and resist t a variety of malicious attacks and thus improve its overall safety and timely resolve for the convergence data loss issues to t reduce communication overhead.
Once it receives the base station data message about the requirement, take periodic data collection.
Wireless sensor networks data aggregation scheme not only reduce the data accuracy and increase redundant data to gradually increase the aggregation efficiency.

Introduction Alkali weight-reduction wastewater is from Alkali weight-reduction process which is designed to give the poly (ethylene terephthalate) (PET) textile a silky property, as well as to improve the dyeing capability.
Alkali weight-reduction wastewater discharged from the PET textile weight-reduction process of some plant was prepared.
A series of alkali weight-reduction wastewater samples are adjusted to various pHs with hydrochloric.
That is responsible for reduction of the recovery rate.
Ash content transmittance Recovery rate Purity (ppm) (%) (%) (%) A 510 85.2 93.6 96.7 B 2170 67.3 99.9 90.9 According to above data, it can be deduced that purifying mother liquid by coagulation-sedimentation is effective on improving the quality of recovered TA.
