However, due to the high sulfate concentration (around 850 mg/L) in influent, sulfate reduction will be stimulated in CWs.
In this study, nitrite and nitrate were used as competitor with sulfate for electron acceptor to prevent the sulfate reduction.
For instance, the cumulative mass removal based on one-year operating data approached 80% for benzene and 88% for total BTEX in a study of pilot scale upward vertical flow mode wetlands equipped with subsurface aeration lines [6].
Results and discussion Both nitrate and nitrite out competed dissimilatory sulfate reduction successfully and there was no difference in the addition of nitrate and nitrite on the influence of sulfate reduction (Fig. 1).
Conclusion Plants can stimulate dissimilatory sulfate reduction by the release of organic carbon from their roots.

It is needed to reduce the input data set by using the data preprocessing method in order to reduce the complexity of the BP neural network computing and speed power load forecasting.
Then for any period i, the influencing factors of power load data and historical load data constitute an object xi={A1,i, A2,i, … , Am,i, yi} on the field U={x1,x2,…,xn}.
Discretization of the Attribute Values of Training Samples Since the rough sets theory can only deals with discrete data, we discretize the data using method of the fuzzy membership function [4].
Data from July 1 to July 15 are the training samples, and data from July 16 to July 22 are the test sample.

Also, more simply (and without material substitution), many suspension and chassis parts can realise secondary mass reductions from reduction in their size that result from mass reductions elsewhere on the vehicle.
Automakers embrace AlMMCs The race for mass reduction.
Likewise, Nissan has a target of a 15% reduction by 2015, representing over 227 kg reduction from their 2008 average light duty vehicle [13].
It was noted that there was need for systematic database that relates properties to processing parameters or between laboratory test data and actual performance.
Validated property data sets for AlMMCs were needed in the form of design allowances for product design, and as inputs for Finite Element Analysis (FEA) as well as for microstructural modelling [37].

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.

Therefore the isolation technology for high-rise structure also has better reduction vibration effect.
Test Data Analysis Acceleration time history analysis.
Due to sensors placed the top failed in test, the data collected were abnormal amplification, so they are not in the table.
Layer displacements of model structure concentrated in the isolation laye mostly, it is consistent with principles of isolation and reduction vibration.
Therefore, the isolation technology for high-rise structure also has better reduction vibration effect.

A large amount of industrial data are accumulated, these industrial data implies the relationship between the process parameters and production rules.
When operational pattern database has a large amount of data, attribute reduction method provides the necessary conditions for fast matching of operational pattern.
In this paper, a PCA method based on data for the attribute reduction of operational pattern is adopted, which improves the matching speed and accuracy of the operational pattern.
Consequently, it needs data reduction, and then it is the pattern matching. 3 Fast Matching Algorithm of Operational Pattern Considering the nonferrous metallurgical process with the characteristics of many process parameters, coupling, and containing noise of the data, a PCA method is introduced in this paper[7].
Secondly, choose production data of December, 2010 for simulation.

This paper focuses on a new method of aerodynamic drag reduction.
This conclusion will have profound guiding significance in the aerodynamic shape designing and the aerodynamic drag reduction of an automobile.
The traditional methods for drag reduction include integral optimization, local modification and adding drag-reducing devices [2,3,4,5].
CFD method is efficient and cost saving, and besides, it can simulate the condition and obtain the data which experiment cannot [6].
Drag Reduction Based on Isobaric Surface The simulation of flow field around an automobile has much similarity with a pipe flow.

Network packet loss rate testing Collect data through No. 4,5,6,7 sensor nodes.
Export log data from the coordinator node database, the test results is shown in Table 1.
So it indicates the data transmission stability and reliability.

X-ray diffraction (XRD) data of AuNi alloy was acquired by a Bruker D8 advanced X-ray diffractometer using Cu Kα1 radiation (λ = 1.5406 Å) at a step rate of 0.02 °/s.
Compared with the fcc Au data (JCPDS, No. 4-0784), the diffraction peaks shifted to higher 2q values.
These data were agreement with the initial compositions of Au and Ni.
Methanol tolerance is an important criterion for selection of cathode materials for the DMFCs, which can be determined by comparing the data obtained from the solutions with and without methanol.
The sample data for plotting were taken from Fig. 4c at the potentials of -0.6, -0.7, and -0.8 V, respectively.

The Kalman filter can be applied to remove noise or artifacts without affecting other crucial data [12] [13].
Numerical data analysis and computation are done with this application.
The Kalman filter is used to eliminate distortions and noise from a signal without compromising other crucial data.
The Kalman filter is capable of foretelling and examining relationships between various sorts of data.
