Baseline can fix the configuration of product data at different stages, facilitate query and reuse data of each design stage, and ensure the data is traceable.
It provides a formal data standard that subsequent work has to follow.
Data of new parallel stage are managed as normal data.
The data control rules of parallel design process are given in Fig.4.
Several important issues, such as mechanism of data version control, configuration control, and data sharing, require further discussion and study.

BCI Experiment and Data Acquisition The data set consists of EEG data from five healthy subjects.
The experimental data were recorded with 22 Ag/Agcl electrodes, spaced at 3.5cm intervals over the primary sensorimotor area (SM1).
All data recorded in the experiment were used in the study. 3.
(10) The log transformation serves as to approximate normal distribution of the data.
Furthermore, more channels were not only waste of time but also troublesome for the data acquisition preparation work.

From the data analysis of positron experiments the average lifetime τav of the two main components ( )2211 τττ IIav += and trapping rate κ = I2/I1 (1/τb - 1/τ2) [where τb =I1/τ1+ I2/τ2] were deduced on the basis of the two state trapping model [10] .
In addition to the increase of the amount of Mn and Mg atoms surrounding the excess vacancies [11] and the presence of Mn and Mg may be the reason for the reduction in the size of defects.
These results are in good agreement with the data obtained by Abdel-Hady et al

The reduction of Hv is associated with the annealing of vacancy defects as well as a reduction of the localized valence electrons concentration at the positron site. 3.

The cigarettes used are filter less types so there is no reduction in pollutant levels at the beginning of cigarette combustion.
All data on the decrease in concentration will be processed into a percentage and the amount of CO gas adsorbed, then the mass of the activated carbon after the test will be weighed to see how much the mass increases.
The excessive amount of metal inserted into activated carbon will result in the closure of pores resulting in a reduction in surface area.
From the data of decreasing CO gas content for all NiO modified adsorption tests obtained with the overall adsorption ability with a sequence of Mod 0.5%> Mod 1%> Mod 2%.
The cigarette smoke adsorption test looks at data from the purity of the air content in the adsorption test box.

Based on the GIS technology, NDVI indexes have been used as main data source in this paper.
Method Data acquisition and pretreatment This paper adopts the United States of America NASA WD center free download MODIS NDVI products as the main data source, the spatial resolution is 250 M, time resolution is 16 days, time series from 2000 to 2009.
The procedure of image processing was geometric correction, projection transformation and mosaic, the annual data from the average, as the study area the annual average value of NDVI.
Results Interannual variation of vegetation coverage This paper uses the maximum synthesis method for synthesis of MODIS 16 days NDVI data processing.
Purple represents the reduction of area, mainly in the study area of the southeast and southwest.

Experimental data were used to estimate the diffusion coefficient.
Works reported in the literature also showed a reduction in the effective drying time when a tempering period was used [17,18].
The theoretical solution was fitted to the experimental data set for a suitable choice of diffusion coefficient in each continuous drying period.
The data of the dimensionlessaverage moisture contents are joined along the straight line, which shows the suitability of the model to describe the rice drying behavior.
The comparison between the experimental and predicted data confirms the validity of the model and the GBI method to obtain solution of the diffusion equation.

The investigation uses real data from material gatherers’ association in the city of Itajubá, Minas Gerais, Brazil.
The research utilizes data from a recyclable materials gatherers’ association from the city Itajubá, located in the southeastern Brazilian state of Minas Gerais.
Materials and Methods Data collection for this study was carried out by means of interviews and direct observations.
To facilitate the geo-referenced data collection of the ACIMAR collection and transportation system, a GPS device was used (Garmin Oregon 300).
In doing so, data were collected for all stopping points along the route, the corresponding neighborhoods, the distances and total times for each trajectory, the speed driven, etc.

The CT-scanned or MRI medical image data are processed first in order to obtain RP-acceptable STL file format.
CT Data in DICOM format was loaded into Amira (Mercury Computer Systems, Inc., www.tgs.com), a commercial image data processing software, in order to convert the images to STL file format CAD file for RP system input.
Noticeably, comparison data here did not include the binder cost, fabrication speed, surface finish, and post processing time of Z310 and Z510.

A detailed discussion of the strength data and a full Weibull statistical analysis are in Ref. [1].
(e.g., wheel depth of cut or table speeds), all data converges into one band.
The maximum crack size for any silicon nitride from our review of other literature data was ≈100 µm.
Nearly all the data fit the same trend.

Compared with a reference design, a significant reduction in the total power consumption about 300W, with the well control in temperature, delta factor and die life, has been achieved by the optimization.
The penalty fitness function presents the better performance in the reduction of the iteration generations and computational cost to the jump fitness function. 1.
The design parameters involving the total number of passes, partial reduction, die angle, bearing length ratio and loops in capstan, are selected as the input design variables of the optimization, which are listed in the Table 1.
