Data logging for dimensional accuracy.
TLS is a non-selective method of spatial data acquisition (Fig. 2).
According to the instrument used for the scanning, the accuracy of TIN model is up to 2 mm for smooth surfaces (some instrument allows to repeat the measurement of discrete points several times, what leads to data noise reduction).
The technology of Terrestrial Laser Scanning (TLS) is suitable for this purpose allowing efficient data collection and therefore post processing of this data set.

Successful WfMS deployment results in significant process cycle time reductions, cost reductions, improved accuracy, greater control, and greater worker satisfaction.
For example, productivity gains from process automation of 5% to 30% and cycle time reductions of 30% to 80% [1].
After a proper e-service provider has been selected through a dynamic service binding process, the Workflow Engine will send a SOAP message that contains the input data of the requested e-service operation to the E-Service Adapter at the e-service provider’s site to invoke the e-service.
After the invocation is complete, the E-Service Adapter encapsulates the return data into a SOAP message and returns it to the e-service requester.

By adding nutrients, control of organic concentration of inffuent relatively stable (at 300 ~ 350 mg/L range), so the NH3-N concentration of influent is about 30 mg/L, hydraulic loading is 1.07 m3/m2●h (corresponding influent 4.0 L/h), then change air-water ratio to determinate relevant data.
In condition of COD concentration of inffluent maintained at 300 ~ 350 mg/L, NH3-N concentration maintained at about 30 mg /L, the air-water ratio 5:1, followed by changing the hydraulic loading on COD and NH3-N treatment the experimental data shown in Fig. 3.
Data show that distribution of aerobic heterotrophic bacteria microorganisms and autotrophic nitrification of degradation organic in the filler in the spatial is different.
Competitiveness of heterotrophic bacteria on nutrients and oxygen better than nitrifying bacteria, become the dominant strain at the bottom of space; reduction of the nutrition in the upper part decreased the number of heterotrophic bacteria, nitrifying bacteria carry out normal metabolic activity, so the active nitrifying bacteria in the upper layer in the filter column.
The air-water ratio is too large, the dissolved oxygen concentration in the filter did not increase, but more bubbles, making cross section area reduction, a direct result of hydraulic retention time shorter , treatment ineffective .

Before and After Treatment Data Analysis.
In this step, calculations were carried out using initial data on the quality of the cold air basin cooling tower.
The reduction of sulfate ions after treatment ranges from 79% to 98%. 2.

Support activities for CO2 reduction and carbon neutrality is also highlighted in another series of European and global agreements such as Clean Europe or the Net Zero Emission by 2050 Scenario [1, 2].
Research in the field of hydrogen storage is being developed in the field of compression and reduction of the energy intensity by liquefaction of hydrogen through storage in salt caves or underground caves.
Fig. 5 XRD data of TiVCrCuNb, TiZrNbMoHf and VNbMoHfTa bulk as-prepared materials.
Based on the prediction theory, with limits correlated to δ ≤ 6.6 % and ΔHmix > −12 kJ/mol the assumption of the formation of a solid phase system lies on the edge of this region and two single-phase BCCs materials were successfully prepared from the calculated data.
The microstructure of materials was examined and together with XRD diffraction data confirm formation of prediction expected single solid solution structures of TiZrNbMoHf and VNbMoHfTa material.

The row control line is as a trigger, and their M column control lines of this row control line are as a set of control data, it is one dimension array; the numbers of its element are M.
The combination of the scanning of row control line, the control data from their column control line and series structure of switches contributes to the achievement of managing multiple switches with less control components.
The reduction of power consumptions is the sum of those of 538 power switches.

The range of measurements provides a large amount of experimental data on temperatures, flow rates and pressures in the engine cooling system.
Then we could simulation results in each individual combustion engine checked by the measurement data.
There is also good to see a reduction in temperature to the cooling channels.
The main point is to calculate the temperature of the exhaust valve seat using the FEM The range of measurements on the engine provides a large amount of experimental data on temperatures, flow rates and pressures in the engine cooling system and especially the effect of different configurations on the adjustment of temperature in the cooling mode of the temperature in the monitored areas of valve seats of the exhaust valves.
For temperatures of the valve seats is important (known) the observation that the temperature reduction is needed to ensure an increased flow rate of the coolant in the cylinder head parts, which are measured.

Lack of electrical conductivity data for various nanofluids in open literature is another challenge in nanofluid application in fuel cell. 1.
Higher temperature than this may leads to membrane overheat or excessive drying which will then result in performance reduction of a fuel cell.
Lower temperature is also not favourable as it can lead to flooding issue due to lower water saturation pressure at lower temperature and also reduction in kinetic energy which is not favourable in term of reactant reactions [2, 6].
Nanofluid application and challenges has been thoroughly reviewed by [3, 12] which covers applications mainly as a heat transfer enhancement and friction reduction devices.

Obtained neutron data showed that all studied samples contain coexisting Mg and MgH2 phases.
Using the Rietveld method obtained data were refined and the phase composition of the samples was determined.
Obtained neutron data and phase composition of the samples are shown in Figs.1, 2 and in Table 1.
Analyses of neutron diffraction data of the first and second samples show that the ratio of the Mg and MgH2 phases is similar to percentage, obtained by the X-ray data (60% of Mg and 40% of MgH2).
Neutron diffraction data of the partly desorbed samples of MgH2.

Continued corrosion of reinforcement causes a reduction of total loss of bond between concrete and reinforcement. [1, 2] Introduction STN EN 206 [3] classifies concrete surfaces exposed to chlorides dispersed in the air (spray area) as the exposure class XD1 and parts of the bridge exposed to splashing containing chlorides (splash area) as the exposure area XD3.
Fig. 1 shows the failures in terms of Serviceability Limit States (SLS) and Ultimate Limit State (ULS) during the active stage of the corrosion of the reinforcement: • SLS 1: depassivation of the reinforcement, the corrosion of the reinforcement starts • SLS 2: reduction of the cross-sectional area of the reinforcement • SLS 3: cracking on the surface of concrete • ULS 1: significant reduction of the cross-sectional area of the reinforcement and the bond • ULS 2: spalling of the concrete cover • ULS 3: the probability of failure (PoF) limit value was exceeded.
The duration of the active stage of the corrosion of the reinforcement may be determined as follows: (3) tp is the active stage of the corrosion of reinforcement [years] c concrete cover of the reinforcement [mm] d diameter of the reinforcement [mm] vcorr corrosion rate [μm/year] If there are not enough experimental data and specific environmental conditions impacting the structure, the speed of the corrosion may be determined according to Table 1.
