• Cost reductions and improvements in mass production technologies, like MEMS technology, enabled manufacturers to implement more and more electronics and sensors into products (as tire pressure monitoring [2] or consumer electronics equipped with sensors and wireless functions
) • The trends towards process automation, safety and comfort require more and more electronics for data acquisition, processing and communication [3]

In this study, we investigated ultimate bond stress between steel rebar and Steel fiber reinforced ultra-high Strength concrete to give low data for development length determination.
As shown in Fig. 3 (b) ~ (d), steel fiber significantly increase the slip without stress reduction.

It shows us that the numerical simulation results and experimental results had a good fit.This shows that the entire axial pump flow field numerical simulation results are with high accuracy,it also provided a relatively reliable data to support prestressing load on the wheel later. 2.2 Impeller structure domain calculation The impeller is the core component of the axial pump,its performance will directly determine the quality of the axial pump running.So modeling calculation of axial flow impeller is crucial.As used herein, the impeller material is structural steel,modulus of elasticity is 200, density is 7850, the Poisson's ratio is 0.3, yield strength is 250,tensile strength is 460. 2.2.1 Impeller modeling and meshing Here is the figure 3,runner model was established in UG,than it was imported in ANSYS,and axial flow runner had been divided by ANSYS WORKBENCH meshing tools.The number of the grid in runner is 197194, and the number of nodes is 286782.
First three vibration mode of the prestressed impeller in water Table 2 and Fig 7 show that the natural frequency of impeller in the water and it as compared to the air, has a very significant decrease in the case of prestressed.Vibration of water points can be caused by the impeller system,the system energy radiated,meanwhile structural natural frequency drops.And a reduction in the frequency of each order are not the same,a decline ranging from 5.2% to 29.6%.The amplitude is also reduced by the damping effect caused by water. 4 Conclusion 1.Vast majority of orders natural frequency after loading prestressed had no significant change through a one-way coupling method, the structure itself did not appear obvious stress stiffening, inertia force of structure and the force of water bodies for the impeller did not affect the natural frequency on the whole 2.significant damping effect of the aqueous medium for the entire axial flow rotor structure was found by the method of APDL command

With regard to this situation, reduction of defective articles and moving technologies during the production process become critical issues.
The resulting analysis data are investigated to characterize near field flows under below the FPD.

The hot band was cold rolled to a thickness of 1.0 mm, corresponding to the thickness reduction of 85%.
Note that the volume fractions of the particles are derived with the data for pure aluminum because the exact composition of the particles is not known.

Further data analysis tools allow the determination of the location and the amplitude of the maximum strain, the global strain distribution and behavior of crack growth, which are important parameters for material testing and fracture mechanics.
A reduction of the used number of pixels allows even measurements in the several 100 kHz range.

These applications prompted increased interest in growth of high quality, large diameter single crystals with defect reduction.
The data obtained at the previous time step provide the necessary information (normal carbon flux, growth rate) for the next time step, and the computational mesh is regenerated between the steps in order to take into account the geometry modifications.

The samples were solution treated at temperature 495℃ for 30 min in an electrical resistance furnace, which was determined on the basis of literature data, and cooled with water, secondly, the samples were subjected to preaging treatment with the temperature of 120℃ for 1h.
Then compression deforming above recrystallization temperature at 450℃ was exerted on samples by universal testing machine, and the compression ratios were calculated by height reduction from 10%, 20%, 30% , 40%, 50% , 60% to 70% respectively.

The expected application is short-range and high-speed wireless LAN for transmitting large information data such as Hotspot.

The reason of this excellent compatibility between dielectric and electrode layer was the control of thermal property through the reduction of thermal expansion of TiN by addition of AlN.
Each of the data point shows an average value taken over three measurements.
