The tensile stress data were analyzed using the Weibull statistical distribution, and SEM was used to characterize the surface modifications caused by the treatments.
Fig. 5 shows an example of the plot of the data using the Weibull analysis.
The increase of the deformation capacity of the fibers submitted to mercerization was attributed to the removal of hemicellulose and to a reduction of the compactness of the fibers.
The tensile stress data and the surface aspects of the fibers submitted to mercerization could be qualitatively described using the Weibull modulus.
It was not possible to establish a similar correlation when enzyme treated fibers were analyzed using the Weibull statistics, although the experimental data adhere very well to the Weibull distribution as inferred from the very high correlation coefficients obtained between the experimental data and the theoretical curve.

Fieldbus adopted to realize data transmission between master and slave.
It can realize the data transmission between the stations, so as to realize independent control and cooperative control.
After PLC collects various parameters and state of the control system, upper computer gets the data of field equipments in real time through the fieldbus network.
PLC compares the collected data with predetermined level precision value.
If the data exceeds the set value, PLC will send commands to the actuators.

] used interpolation of empirical data thus negating the need for localised equations to be solved, which can be seen as another approach.
However the large number of variables to take into account and the lack of wide ranging data for these variables seriously limit the usefulness of this approach.
As such empirical data for these values would be required when looking at each temperature in question, which is clearly not useful for the purposes of the model.
Thus, tables of empirical data of entropy and enthalpy of Hydrogen, Oxygen and Water were collected [[] R.
This calculated data was then graphically analysed by plotting the individual data points in terms of entropy/enthalpy against temperature.

The experimental data regarding the residual stress profiles due to the deep rolling process and the resulting workpiece distortion were used to validate the simulation, so that an adjustment or a calibration of the thermometallurgical and thermomechanical material data was possible.
With a further increase of N in the same machining area, that is, with a reduction of the lateral tool feed, the workpiece distortions increase to -0.115 mm for ten rolling tracks.
The single-track test showed a reduction of the initial distortion by 0.006 mm.

In view of the inherent contradiction between mass data and real-time browsing in Highway 3D Visualization System, this paper proposes an edge folding algorithm for weighted average elevation base on vertex degrees, which will improve the model simplification effective.
Therefore, how to deal with the terrain data real-time 3d simulation system is the road to solve the problem and this directly determines the performance of the system, the feasibility and stability.
LOD method not only reduces the geometric distortion in graphics hardware, lighting calculation and rasterization of time, but also reduces the bandwidth bottlenecks when transmitting data from memory to graphics card.
The main aim of "Video-based Automatic Incident Detection of highway network monitoring system" is that using the existing highway surveillance cameras to provide video image and video data, and using image recognition technology to automatic identifying traffic abnormity, moving station detection, vehicle tracking, and automatic traffic incident detection.
Fig. 1. 3d visualization of TIN terrain (with 721,735 vertexes, 1,442,577 triangles) Continuous and reversible of LOD terrain model The magnitude of the terrain data scatterplot determines that the terrain model must contain abundant triangles.

The data began to be recorded at 0.5 h after the cement was mixed with water, and the determination age was 72 h.
Finally, the data of low pressure and high-pressure are fitted for subsequent data processing.
Data were recorded every 1 min, and the test period was 7 d.
The test was carried out under the condition of relative humidity (60±5) %, and the data was recorded every 1 min.
According to the pore structure and compressive strength data at the age of 180 d, the steel slag content of 20% can improve the pore structure of cement paste, keep the porosity at a low level, and make a high compressive strength of hardened calcium sulfoaluminate paste at the same time.

Our data indicate that the TiO2 nanowires are synthesized uniformly and also the Ag nanoparticles are coating well on these nanowires.
To coating these nanowires with Ag nanoparticles, we use a reduction method [11] to get Ag nanoparticles from AgNO3 solution.

Table1 Experimental data of straight and parallel degree
Figure 6 Percentage of straight and parallel
From Table 1 and Figure 6, we can see that the cotton percentages of straight and parallel are less than those of fibers, so it is clear that the flats-delivered device is better for fiber adaptation.
The percentages of straight and parallel increased with the reduction of lengths.
