In addition, the procedure of data transferring between
commercial package and in-house solver for the preparation of input data for in-house solver has been
developed.
Data transfer: Commercial FE package and in-house solver.
The block diagram for this data transferring between the in�house solver and commercial packages is shown in Fig.1.
Local numerical tensile test model in ANSYS is prepared by numerically cutting (extracting) both geometric and residual stress data from the global 3-dimensional model after finishing thermal elastic -plastic analysis.
But the purpose of this study is to prepare and develop the procedure of simulating dissimilar welded model and transferring the residual stress data from the in-house solver to commercial package as initial value for further analysis.

As a result of the experimental study, the following results can be drawn: Following freeze thaw cycles, reduction in the bending and tensile performances of the biaxial glass fabric reinforced composite samples as well as matrix samples were obtained.
Load cell, LVDT and data logger were set up on the tension sample, load and displacements were also read from the crosshead movement of the machine.
When it is subjected to freeze thaw cycles, a significant reduction in the deformation capacity of the unreinforced mortar has occurred.

The extent of reduction in the quantity of Ca(OH)2 depends upon the polymer-cement ratio, polymer type or both.
Heat flow curves and data from XRD experiments can be combined and the early heat flow during cement hydration can be related to different specific reaction [10].
However, the magnitude of reduction in the quantity of Ca(OH)2 is affected by the polymer-cement ratio.

The obtained results show that with execution of cryogenic treatment and tempering, the tensile strength increase owing to the reduction of retained austenite and fine carbides precipitating respectively.
Each effective hardness data of a specimen is the average from seven points.
Conclusions (1) After cryogenic treatment and tempering, the tensile strength increases owing to the reduction of retained austenite and fine carbides precipitating respectively, comparing with quenched state

The sintered Ni-20at%Co rod was cold-rolled into tape at 5% reduction ratio
with the final thickness of 100㎛, and the recrystallization heat treatment for the development of the
cube texture of the rolled Ni alloy tape was carried out at 1000°C in Ar 96% and H2 4%.
X-ray diffraction data of Ni-20at.
The scratched and textured tape resulted in the highest texture development in the diffusion reacted LiNi0.8Co0.2O2 phase while the non-scratched and un-textured Ni-Co tape showed the lowest (00l) peaks development in XRD data.
This texture development of the LiNi0.8Co0.2O2 phase was considered to epitaxial growth of the diffusion reacted region on the c-axis textured substrate with sharp (200). 10 20 30 40 50 60 70 80 Intensity(A.U.) 2 θθθθ ▽▽▽▽ LiNi0.8Co0.2O2 ▼▼▼▼ NiO+CoO (101)(101)(101)(101) (003)(003)(003)(003) (106)(106)(106)(106) ▼ (021)(021)(021)(021) (110)(110)(110)(110) (104)(104)(104)(104) (107)(107)(107)(107) Ni + Co (a) (b) (c) (d) (e) (f) ▽▽▽▽ ▽▽▽▽ ▼▼▼▼▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▼▼▼▼ ▼▼▼▼ 10 20 30 40 50 60 70 80 Intensity(A.U.) 2 θθθθ ▽▽▽▽ LiNi0.8Co0.2O2 ▼▼▼▼ NiO+CoO (101)(101)(101)(101) (003)(003)(003)(003) (106)(106)(106)(106) ▼ (021)(021)(021)(021) (110)(110)(110)(110) (104)(104)(104)(104) (107)(107)(107)(107) Ni + Co (a) (b) (c) (d) (e) (f) ▽▽▽▽ ▽▽▽▽ ▼▼▼▼▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▼▼▼▼ ▼▼▼▼ Fig. 2 XRD data of LiNi0.8Co0.2O2 thin films with different amount of Li source and the surface morphology of the substrate; (a) thermal evaporation

The texture
analysis gives the most direct data on the degree of grain fragmentation under conditions of
deformation.
Obtained data are presented in the form of GPF βhkl, GPF Dhkl, GPF εhkl and so on.
Shown distributions were constructed on the basis of data, obtained for the middle region (3 x 3 mm) of rods Ø 9 mm.
Judging by data of Table 1, in the case of α-Ti rods the used regime of ECAP promotes grain refinement, whereas in the case of Cu rods the revealed tendency does not agree with this effect.
The above comparison are illustrated by the example of X-ray data, obtained by study of ECAP rods from Cu and Ti.

The pressure drop predictions compare favorably with literature data and the coefficient of variation (COV) value for circle grid perforated plate with 50% porosity at Reynolds number 100 was 0.0744 which is out of the range meanwhile at Reynolds number 200 and 400 was 0.0483 and 0.0247 respectively which are in the range of reasonable target for many applications.
On the other hand, this radial reduction of hole diameter assists in stabilizing the velocity distribution.
In this case, the COV will defined as the standard deviation of concentration over the mean of concentration for given set of N data points.
The standard deviation of the concentration can be shown in equations as below: (1) (2) To obtain the data to calculate the COV, a specified number of grid nodes at a cross section identical plane were taken.

System Scheme
The System Design Objective Based on Intel Menlow platform, in the core technology of visual sensing, video image analysis, RFID, GIS and network communication, we designed a road traffic flow parameter monitoring terminal (ITS monitoring terminal) integrated with traffic flow parameters sensing, data processing and data dissemination.
AlphaPowerful data management function The system uses SOL server as database for management.
Monitoring points display the year, month, day curve and data report, then automatically generating a report of monitoring data in the system.
The terminal has such functions as traffic flow parameters sensing, data processing, control, communication and information exchange and release.
After a linear recursive method, the plurality of measurement data and signal parameters are processed to give unbiased estimate of the minimum mean square error.

The fitted polynomials of COP, Ne, Nc were obtained by the MATLAB curve fitting toolbox according to datum from product samples.
(2)With the reduction of R, under variable flow operating state the heat pump unit will consume more than average 8.41% energy, while COP will decline average 7.61% compared with constant flow
(3)With the reduction of R both of the Ve and Vc will decrease so that there will have a energy saving of Ne and Nc.When R ranges from 30% to 100%, the mean energy conversation rate of Ne and Nc are 49.38% and 38.86%
(4)With the reduction of R, both of tein and tcout decrease due to the declination of temperature difference.

Experimental data on the EC of the hybrid NF was obtained using an EC meter at different mixing ratio and temperatures.
The experimental data was divided into three main parts, which were randomly categorized as train, validation, and test sets.
The train set contained 70% of the data points, while the validation and test set each contained 15% of the data points
RMSE= 1ni=1nσactual-σpredicted2 Where n is the data points for the experiments, and σ is the EC ratio.
Fig. 2 and Fig. 3 shows that an augmentation in the mixing ratio led to a reduction in the EC ratio of the hybrid NF.
