The data point to a reduction of the limiting oxidation currents of the sulfide alloys prepared by high-rate cooling.
The obtained data are related to sulfide alloys cooled in equilibrium or nearly equilibrium conditions.
Methods The electrochemical processes were studied in an IPC hardware system and the data were processed using an IPC-2000 software.
According to the data reported herein, the anodic oxidation of the nickel sulfide pelletized at a rate of 103 K/s was also accomplished via a stepwise mechanism.

Equipped with strain gauges and other measuring sensors, it will provide experimental data which can then be used for nonlinear aeroelastic analyses for other such kind of structures.
Aircrafts with high aspect ratio wings can experience large wing deflection during normal flight operation and this could cause reduction in the flutter speed.
The results indicate a significant change in the structural frequencies and a significant reduction in the flutter speed.
The slender high aspect ratio wing having very flexible aircraft has coupled nonlinear aeroelastic/flight dynamics and it is expected that it would provided valuable data in support to code validation.

Then the data acquisition is carried out.
The point cloud of the connecting rod 2.2 Data Processing The software Imageware is used for the connecting rod data processing.
The enormous data has brought a lot of trouble, especially for partition, and reduced the processing speed of the computer, so it must filter the data by“Modify-Data Reduction-Space sampling”.
First, the data point clouds is fit to curve, then the control line data is introduced to Pro/E, and the curve is constructed to surface.

The adsorption data could be well fitted by pseudo-second-order rate model.
The results show that adsorption experimental data of PT to Cr(VI) could be well fitted by the classic Freundlich equation, as shown in Fig.3.
There is a strong correlation coefficient higher than 0.999 between the fitting function and experimental data.
Oxidation-reduction reactions also usually happened at this time.
The process was controlled by chemical adsorption, mainly including oxidation-reduction and chelation reactions.

By collecting and analyzing the perception data in terms safety, it provides decision basis for improving facility design and reduce hazards in the workplace. 1.
The difficulty lies in how to quantify the risk reduction or reduction in severity of problems associated with the workplace due to the use of the new technology.
Whose comments will form the source of data for analysis to eventually identify an optimal workplace layout design. 4.

It is well-known that seismic disaster will cause serious damage, so the prediction and evaluation of seismic loss before earthquake event happened can provide foundation of disaster reduction program.
Macroscopic Vulnerability Model Based on GA-ANN 2.1 Collection and Pre-processing of Sample data From ref.4 -5, we picked out 80 sample data about the loss estimation results of earthquake which happened at different seismic intensity zones.
Normalizing the input-output data sets between certain ranges is an important step, this improves input-output generalization to yield accurate forecasts.
In this paper, eq.2 is used to normalize the raw data, after such pre-processing, the convergence time is significantly shortened
The data about seismic intensity, population density, per captia GDP and unit area GDP were input to the well-trained ANN model, the results as shown in tab.3 showed the output of the loss ratio of different areas, thus the estimation result could obtained.

According to this phenomenon, this paper compared the two different bearing floating slab noise data, studied their dynamic characteristics under train loads.
As the lines with a large number of steel spring FST structure are in operation, there are low frequency noise like "gu long gu long" in the carriage when the train runs over the steel spring floating slab area, which affects passenger’s comfort, and also cause the more and more attention of researchers[1]-[3]. 2 Noise testing data in carriage when train runs over different track area Aiming at the problem, noise data from different floating slab areas was measured in the carriage.
One group of data (Fig.1-Fig.3) is the train run from common slab track to steel spring FST area.
The data from Fig.6 shows: noise in the vehicle rises unapparent when the train moves over high damp floating slab.
The test data in Fig.5 verified this method is feasible.

Introduction The SLM process is an additive process used to create metal parts with complexes shapes from CAD data.
The consequences are the reduction of fatigue life of the part or the initiation of cracks.

The physical meaning of the data are studied and illustrated as well as its representation methods.
Experiments are conducted to verify the range finding accuracy of the sensor and the data visualization method is also introduced.
Coordinate System Conversion Distance data of each frame is constituted by 683 distance metric.

., reported on a normalized-weight-percent basis) showed only a small reduction in Al within the alloy (Points 1 and 2), but no reduction in Fe or Cr.
The corrosion was sufficiently severe that massive Fe-rich scales were formed even though there was no obvious large reduction in the Al content in the alloy surface.
The data showed that the only small areas that were enriched in Na (Points 13, 14, and 16, one of the fluxing elements added to the Al pool), were found at the outside of the scale.
The x-ray data showed it to be strongly depleted in Cr, especially near the surface, leaving behind primarily mixed Fe and Al oxides.
X-ray data indicated a significant reduction in Cr in the remaining metal (Points 1 and 2) and the formation of Cr-rich oxide precipitates throughout the vesicular region (Points 3 and 4).
