The 3D model can be integrated with the loading conditions and material properties, to provide the detailed data for analyzing the structure.
The surveying technique of photogrammetry entails extracting input data from two-dimensional images and mapping them onto a three-dimensional object space.
Three settings on the camera should be disabled if they are present: 1) Image Stabilization (or 'shake reduction') must be off; 2) Auto-rotation (detects portrait vs. landscape) must be off; 3) It is recommended to lower the camera's 'sharpening' setting (i.e. make images less sharp).
The result 3D model may well satisfy the application needs in bridge simulation visualization in 3D; and that can be integrated with the loading conditions and material properties, to provide the detailed data for analyzing the structure.
This paper has accumulated the experience in data acquisition and modeling methods.

The system can collect and dispatch the real-time data of automotive nodal voltage, active power and reactive power and so on.
It is an important measure for loss reduction and energy saving with less investment and quick results
In the operation, if the real-time data is unqualified or the channel fault happens, results of power flow calculation will be likely unable to use.
That can ensure plants with intact real-time data to participate in reactive voltage optimization control alone.

As to the adsorption isothermal curve shown in Fig.2, the question on what kind of adsorption it should be classified in or what formula should be used to express it can not be simply answered by the figure rendered on the basis of data obtained by isothermal test, this, we believe, is inaccurate.
The adsorption type and associated adsorption isothermal formula can only be decided when data obtained from test is processed by mathematical method.
Following this philosophy we get test data for mathematical treatment and the result shows Freundlich is a better fit to the adsorption of selenium by anion exchange resin of 201×7, with associated formula as follows: (4) Where in Freundlich formula, k is adsorption capacity when concentration c=1, it can roughly indicate the volume of adsorption.
That is mainly because that the OH- in alkalescent solution may compete with SeO42- to react with the resin and leads to reduction of selenium removal by resin.

Results and Discussion Fig. 1 shows the XRD pattern of the CuAlO2 powders, all the diffraction peaks match well with JCPDS data card no. 35-1401, showing that the crystalline structure of the CuAlO2 powders is 3R polytypes which belongs to the R3m space group, and has a trend to grow in the (0 0 l) orientation [15].
The measured lattice parameters are a = 2.8553 Å and c = 16.943 Å , which are closely to the standard lattice parameters of JCPDS data card no. 35-1401: a = 2.8567 Å and c = 16.943 Å, the measured lattice parameters also agreed with those previously reported for this material [16] as well.
Fig. 1 XRD pattern of the CuAlO2 powders Fig. 2 XRD patterns of CuAlO2 ceramic The XRD patterns of the CuAlO2 ceramics are shown in Fig. 2, all the diffraction peaks match well with JCPDS data card no. 35-1401, no other peaks are detected in the bulk samples, which indicates when the sintering temperature is over 1000 ℃, all the samples are pure CuAlO2.
Even at the shortest holding time (5 h), all the diffraction peaks match well with JCPDS data card no. 35-1401.
Samples with lower sintering temperatures have the smaller grain size and lower density, which will process higher rates of scattering of the phonons with longer mean free paths, leading to the reduction in the lattice thermal conductivity.

It provides the possibility to lower the uncertainty of alignment, but on the other hand it also yields low diffuse reflectivity, which is prone to cause issues of data reduction for optical measurement techniques.
Using multiple scanning angles assures more surface coverage but double coverage is inclined to come with redundant data resulting in lower repeatability and longer measurement time.
Fig. 7b) states that the accuracy of three-angle scanning is more than 10µm better than four-angle scanning, in the measurement of the z direction, since the redundant data yielding bad results.
The time consumption of the tactile measurement is 0’49’’, while optical measurement is 0’53’’, which takes into account both the measuring itself and the processing of the point data.
It can be obviously deduced from Table 2 that the laser line scanning strategy provides a superior performance compared to the tactile measurement, due to the time reduction for both alignment and actual measurement.

The post-operative drainage was active and it was kept for maximum 48 hours; haemoglobin levels were evaluated after the minimal value detected, regardless the moment when this was diagnosed Results The demographic analysis of the two groups is presented in Fig.3, the data revealing a typical aspect for the onset of the osteoarthritis ( after 50 yrs) Figure 3- The age of the patients ( yrs) Another parameter which was evaluated was the duration of surgery, as the connection between the intensity of bleeding and the duration of surgery is well known.
Fig.3- Post-operative drainage ( ml) As for the decrease of haemoglobin, this is somehow parallel to the previously presented data, and higher for the group who did not receive FS., as shown in Fig.4, most of the patients who had a variation of more than 20% requiring blood transfusions.
The data presented in this paper are concordant to those described in the literature; the studies of Sabatini and Notarnicola [30, 31], as other’s authors, too, showed significant reductions in drainage output, haemoglobin loss, need for transfusions, time of functional recovery, and length of hospital stay[32, 33, 34].
The observational research performed by the authors confirmed the data from the literature and underlined the clinical significance of the properties of this biomaterial- properly indicated and applied, with a proper surgical technique, it can be a very useful tool for modern orthopaedic surgery, due to its efficacy and safety, as well References [1] William D.

This allowed significant reduction in problem size and thus sufficient mesh refinement at the crack tip region, yet providing reliable results from the FE simulations.
This is not a crucial issue as no experimental data are included in present work.
Analyses using AR and LUCF load cycles were also performed to provide data for comparison.
For the interaction studies of the cylinder with surface crack on the other hand, the RS was generated from stress data from autofrettage of a pre-cracked model.
For the analyses that used this material model the initial RS field was generated from the autofrettage data of the un-cracked pipe following the procedures described above.

Recycling concrete wastes will lead to reduction in valuable landfill space and savings in natural resources.
On the other hand, the Eq. 2 was obtained by fitting experimental data obtained for the concrete mixtures prepared with 30% coarse recycled concrete aggregate, whichever the type of cement used.
On the basis of the experimental data reported in Table 4 some comparisons of the drying shrinkage strains of equal strength class concretes can be made.
For the strength class C 28/35, on the basis of data reported in Fig. 2, the compared mixtures are ‘NA-hpc-0.60’, ‘RA-hpc-0.50’ and ‘RA-lpc-0.40’; while for the strength class C 25/30 the compared mixtures are ‘NA-lpc-0.60’, ‘RA-hpc-0.55’ and ‘RA-lpc-0.50’.
By comparing for those mixtures the data reported in Table 4, it can be noticed that, by using 30% coarse recycled aggregate, the values of the measured strains on RACs are lower to those obtained for the reference mixtures of the same strength class, particularly at early ages when the ‘internal curing’ effect is more evident [18].
