A simple data transfer strategy based on a finite element type interpolation of the interface degrees of freedom guarantees kinematic consistency and equilibrium of the stresses along the interface.
Considering deformation of the structure in this example is relatively simple and reduction calculation amount, nodes in both sides of contact surface is constrained consistent in the movement.
The data transfer strategy at fluid-solid interface is based on a finite element type interpolation which is sufficient to guarantee kinematic consistency and equilibrium of the stresses.

Based on experimental data some equations are adjusted and the results obtained are discussed.
The amount of data obtained revealed to be sufficient to adjust a numerical model.
Adjust to the Residual Soil Experimental Data In order to obtain a numerical result for the laboratory results, the equations presented in the previous sections were tested and evaluated.
Figure 3(a) presents the adjust to the data resulting from the filter paper method while Figure 3(b) represents the adjust to the data resulting from the pressure plates.
Models with higher number of fitting parameters tend to adjust better the experimental data, although introducing additional numerical complexity.

As a result, the process reliability of the measurement data is high.
Thinning reduces the data volume which is often required for further processing steps.
Some software is limited to a certain number of points or it takes a long time to process the high data volume.
The manufacturing system uses these data and builds up the part layer by layer.
They can be determined in most cases by DSC (differential scanning calorimetry) and are usually specified in data sheets of additive materials.

Most of the data have been already reported previously [4] and here reproposed only for clarity of comprehension.
Strength and hardness and toughness data reported in the present paper are averaged over 5 measurements.
Averaged data are 5.6 GPa for materials fired at 1090 °C, 5.4 GPa for those fired at 1140 °C and 5.2 GPa for the reference tile.
The fourth column reports data measured on the reference commercial tile.
Data conflict could be therefore explained by taking into account the different heat transfer forms which take place during the two types of firing processes.

The calculation results for the crushed stone coincide well with those recommended by the current Code of《DNV-rp-f107_2010》, which is on the basis of experiment data, implying the feasibility of using this program to estimate the energy dissipating capacity of the geo-materials.
Parrales[4] provided one method which can quantificationally describe the ability of energy dissipation by introducing some factors, such as the factor of energy dissipation, the factor of reduction and so on.

And the simulation results of pressure drop were validated by the experimental data.
Pressure and differential pressure sensors 8. microcomputer and data collector Figure.1 Experimental system diagram Figure.2 Taper pipe diagram Table 1.
This is because, when the diameter ratio grows up, the degree of the area reduction increases, and when two phase flow through the taper pipe, and then the frequency of collisions by the gas-solid flow and the wall increases.

The photocatalytic mechanisms of the sensitized TiO2 nanospheres were attributed to the reduction of bandgap energies and the sensitizing effect of melon.
Although there is a reduced nanoparticle size, the agglomeration of these nanoparticles can significantly decrease the specific surface area which can be confirmed by the BET data.

The CB electrons transfer to dissolve oxygen molecule (O2) for forming superoxide radical anion (O2•-) and further reducing to HO2• and hydrogen peroxide because of the proper position of ECB and oxygen reduction potential.

This results in reduction of peak charging power based on EVs own consumption schedule while they select the best response in energy consumption game.
Whereas, the IEEE 802.16 Wi-MAX has data rate up to 75 Mbps with larger coverage area than Wi-Fi.
First we determine total available resource Rj and fix reference resource RRij for each load ‘i’ at time ‘j’ based on history data, to give an estimate to energy supply and management system of usual hourly requirement of each load.
This method results in reduction of peak charging power during a specified time [10].
