The aim of the present work is the determination of the quality and accuracy of the data provided by the LED structured light scanner Comet L3D (Steinbichler).
In order to use this geometric data and obtain a numerical model, point clouds must be processed using specific applications.
This accuracy value corresponds to the maximum accuracy in data acquisition.
Subsequently, data fusion can be performed by grouping all points in a single file.
The complete process is considered, covering both data acquisition and subsequent processing.

Using the new NEWGPSR protocol, a WSN network is divided into many small networks, and nodes in each small network only store information related to a given data cluster to allow the reduction in total amounts of data transmission, and the energy consumption of the whole network is thus reduced.
3.1.1.1.Cluster head selection algorithm based on node degree
In the LEACH algorithm, the methods to select cluster head are often unstable either in quantity or distribution.A previous study showed that the nodes degree from a large number of the real network followed the probability distribution of power.
When a node demonstrates a sign of energy over-consumption, the data-forwarding function of this node is disabled, a warning signal is sent to its neighboring nodes, and the data transmission path is re-built.
Figure 3.1 demonstrates a data transmission link established following this rule.
Picture of data transmission link In the routing process, each node has three tables: the property table, the route table, and the neighbor table.
Inside,NextNode is the next jump point; FLastNode is the last node of LastNode; SinkNode is the destination for the data transmission; Inter-node data transmission follows the heuristic rule,data are preferentially forwarded to the nodes with relatively high energy according to the information of neighbor table (as shown in Table 3.6).

These data must be on elements features that influence cycle performed by product during life.
These data will be completed for each component.
In the next stage, in SimaPro program menu, necessary data for the recycling of each component are inserted.
Moreover, the precision of analysis of life cycle depends on the accuracy of collected data.
A life cycle analysis is viable only if data used for analysis are also viable.

Taguchi DOE approach was chosen in the present study due to its favorable features, namely the possibility it offers to determine the effect of external disturbances considering the S/N ratio, which measures the interaction between the control factors and noise factors, and ii) its ready implementation, considering the simplicity in collecting data and the practical design.
a DF: Degree of freedom b Seq SS: Sequential Sums of Squares (measures the reduction in residual sums of squares provided by each additional control factor in the model).
c Adj SS: Adjusted Sums of Squares (measures the reduction in the residual sums of squares provided by each control factor relative to a model containing all the other control factors).
As shown in table 6, a suitable agreement between the predicted and experimental data was obtained.

Hence, the high-speed photography will be adopted to determine the initial fracture reduction in this work
Recent years, the increasing attention has been received with respect to near-alpha titanium alloys, and they have been researched as the candidate of material for jet engines as compressor discs and blades because of their light weight and superior fatigue and creep properties at elevated temperatures up to 600 ℃ [14].
Moreover, when the strain is up to 0.916, the observed cracking regions in the images are completely consistent with the practical situation, which manifests that the method for obtaining the critical fracture reduction is accurate and reliable.
It is interesting to find from Fig. 4 that the critical fracture strain data of the present alloy is divided into two parts as result of different values caused by different values (574.8 kJ/mol in α+β phase field and 194.0 kJ/mol in β phase field) [16].
Furthermore, the critical fracture strain data both in α+β phase field and β phase field can be well correlated with parameter.

The literature provides significant data on the oxidation resistance of coatings based on self-fluxing alloys produced using different surface hardening techniques.
Metallographic specimens were prepared using standard technology, which includes grinding and polishing operations with a gradual reduction in abrasive particle size.
The selection of temperature and holding time was based on the literature data [8,10].
Increasing the amount of “Nb+B” powder mixture added to the self-fluxing alloy to 35 wt.% leads to a reduction in the oxidation rate of the material.

During the research, the average air temperature, mean relative humidity and the amount of precipitation varied as shown in Figure 1 (data were obtained from the local meteorological station).
The thermal data tests were carried out by using a DSC 821 Mettler Toledo apparatus (Japan) and STARe software (version 9.01).
Most of the samples (PPH 15GF, PPH 25GF, PPH 30GF, PPH EP, PPH 10T) air-conditioned from the first month, showed an increase in transverse shrinkage values, meaning a reduction in the width of the molded parts.
However, we noted a sudden reduction in the value of hardness during the second month of exposure.
