In database design, analysis of data structure, data flow and data storage of data dictionary is need. it extracted the data according to data diagrams, determined the entities, entity attributes and relationships between entities, obtained the relationship model of the system.

The corresponding relationship between displacement and time is calculated for each tool, then the data of it was imported into MSC.Marc as boundary conditions of each tool. 1.2 Process parameters The process parameters is designed as shown in table 1, the feeding rate ΔZ is considered as the only variable.
a The center section drawing of the Pyramid b The local enlarged drawing Fig.7 The dimension accuracy comparison of different feed rates Analysis of Thickness Reduction Ratio In order to study the effects of different feed rates ΔZ (0.5mm, 1mm,1.5mm,2mm,3mm) on the forming area thickness reduction ratio of the parts, node B(node1149) of the diagonal of the parts is selected as shown in fig.8.
Fig.8 Node selection of thickness reduction ratio Fig.9 The thickness reduction ratio comparison of different feed rates Fig.9 shows that the thickness reduction on the diagonal is more serious than it on the center-line, therefore, we should pay more attention on the parts’ diagonal when we adopt MPCIF.
Figure 9 shows that the bigger the feed rate, the bigger the thickness reduction ratio and the sheet metal is more easy to crack caused by the instability of defects; the change between steps of the thickness reduction ratio curves in ascending order isΔZ0.5, ΔZ1, ΔZ1.5, ΔZ2, ΔZ3, the forming area can get uniform thickness under small feed rate .
Under the same process condition of MPCIF, the bigger the feed rate, the bigger the equivalent plastic strain and the thickness reduction ratio, the springback and bulge can be more serious, the parts can be more easy to crack. 2.

Recently, research on mechanism of runoff and sediment reduction by plant measures became a hot point.
Wang et al. studied effects of grass coverage on shallow flow hydraulic parameters and sediment reduction [5].
Results and Discussions Reduction Effects of Grass on Runoff and Sediment Yield.
Based on the experiment data, the sediment yield rate was significantly and positively correlated to the flow shear stress and increased with the increase of the flow shear stress on both grass and grass plots, which can be seen in Fig. 1.

Experimental data coming from quasistatic tensile tests, carried out on specimens exposed to laboratory air, to a NaCl solution (3.5wt%) and to a methanol solution (95%), will be reported.
These data will be then compared with literature ones, referring to axial-fatigue tests [7, 8] performed on similar specimens exposed to the same environments, with the intent to decouple the effect of the alternating load and of the aggressive environment.
The tests results were then compared with previous experimental data, obtained by fatigue tests carried out on samples having similar geometry and in the same environments [7, 8].
The methanol fatigue data were taken from previous experimental campaigns [11].

Figure 8: Comparison of data of a second sensor (C) with an existing SOM trained with data of a sensor (T) shown in Fig. 7 Almost all data of the damaged structure are located in one node, belonging to the group of sensor breakage, while three nodes belonging to the group of broken test data are not covered by any data point of the comparisons data sets.

Such ERF factor is still lack of confidence to concrete industry prior to deliberate calibrations with in-field real time data.
To account for the structural ductility, strength reduction factor Φ shall be applied to nominal moment Mn depending on the reinforcement ratio, as specified in ACI 440.1R-06 Eq. (8-7) as below.
Since top GFRP bars in bridge deck are more likely to be exposed to environmental attacks, stresses in top bars are investigated for both environmental reduction factors CE= 0.8 and CE= 0.7.
Per ACI 440 design guideline, environmental reduction factor CE is recommended as of 0.8 and 0.7 for applications not exposed and exposed, respectively, to weather and earth.
