IRT and UT experimental data are elaborated with MATLAB codes software for damage analysis and results are implemented to check results with strain and compliance data acquired during tests; data elaboration and post-processing of all experimental results are discussed.
Fatigue test data are recorded with a frame rate of 10 Hz and fatigue results seem to show a significant stiffness reduction increasing load cycles number, as normalized stiffness vs normalized fatigue life in Fig. 2b.
Amplitude data are recorded at regular intervals each of 10000 cycles and resulting data are analyzed as function of probe position on sample ROIs.
A graphical method was adopted on phase data to assess fatigue limit.

Resistivity data have been fitted with the variable range hopping model to estimate the density of state at Fermi level.
The TP does not decrease much due to 5 % of Ru substitution into the Mn site with no change in the crystal structure and has a small effect on the reduction in TP.
The larger Sn+4 ions substituting smaller Mn+4 ions might have induced reduction in average Mn-O-Mn bond angle and lengthening of Mn-O bond length.
In the present case, the resistivity data measured on the La0.67Sr0.33Mn1-xBxO3 (B = Ru, Cr and Sn, x = 0, 0.05) seemed to obey the VRH model when n = 1/4.
This scattering of the carriers at the interfaces and reduction in scattering on the application of magnetic field may be understood in the following way.

Homogeneous charge compression ignition (HCCI) combustion, when applied to a gasoline engine, offers the potential for a noticeable improvement in fuel economy and dramatic reductions in NOx emissions.
The lack of data in the field of HCCI 2-stroke engines is more significant in compare with 4-stroke engines because HCCI studies are more concentrated on 4-stroke engines.
Their experimental data are used for validation of numerical method and profiles of pressure and emissions are compared between model and experiment.

Hill and co-workers [41] used graphene oxide in solar cells, and showed some data on charge transfer, but their cell performance was poor, about three orders of magnitude lower than that of devices utilizing PCBM.
This is also corroborated by the data of Hill and co-workers [41], who attribute the drop in PL signal to the Forster's mechanism for energy transfer which is slower and much less efficient.
Note that we show the Raman data for one particular grade of graphene, since we are only able to pick up the D and G bands of the graphene at relatively high (33 weight %) concentrations.
Data has been normalized according to G band intensity and shifted vertically for better visibility.
Data has been normalized according to G and intensity and shifted for better viewing.

The results will be used as input data for the validation of a mathematical model, that simulate
corrosion process on bronze surfaces as a function of specific environmental condition.
After 5 exposition cycle (Fig. 6) it appears as a compact layer with an average thickness of about 15 µm The EDS analysis carried out in several zone of this compact patina highlight that it is composed principally by copper-sulphuroxygen compounds confirming that the XRD data which indicate Brochantite (copper hydroxysulphates) as principal compound forming the corrosion patina.
The L*, a* and b* parameters rapidly decrease after the first cycles, after this point the reduction trend begins lower.
They reflect the light less than a pure metal , and furthermore the corroded surface is rough and this yields to a further light reflection reduction.
All the data obtained are also interesting to better understand all the corrosion mechanisms which brings to bronze surface degradation.

Literature Review
Research Process and Analysis
The study acquired knowledge on the characteristics of folding chairs and quality function deployment in addition to the applications through literature review and data collection.
The data show that most public using folding chair at home emphasize more on the coordination between the folding chair and the environment.
The data were summarized into the importance analysis of demand quality as shown in (Table 3-2).
The second layer consisted of “structural and form integrity design,” “new color conversion and use,” “aesthetics in chair reinforcement,” “No screws used,” “use plastic elasticity for assembly,” “handle design,” “latch for easy stacking,” “flat surface required after folding,” “Sufficient seat reinforcement,” “Use sliders or pullers to prevent pinching,” “appropriate arch and angle of chair back,” “dimension of seat,” “appropriate angle and contour,” “appropriate height of seat,” “appropriate back height,” “parts can be dissembled and recycled,” and “part reduction.”
Finally in terms of environmental protection, although the rise of green awareness in recent years have urged people to enhance their concepts of environmental product, the survey in contrast did not discover consumers emphasizing more on the reduction of materials and recycling materials for reuse as expected.

Many methods of GO reduction have been introduced and extensively studied by many researchers [7].
This statement is correlated with the data from current-voltage measurement shown in Fig. 5.
Fig. 6 Experimental data (solid line) versus fitting J-V curve (marked curve) extract from single diode model equation.
Resulted fitting curved vs. raw data from I-V characterization is shown in Fig. 6.

With this philosophy, it is possible to produce a variety of products with a minimum of inventory and the lowest level of quality defects .JIT leads to many operational benefits such as the reduction of work-in-process inventory, the reduction of floor space required, the reduction of manufacturing lead time, an increase in worker productivity and increase in inventory turnover [18].

In order to better use the damping vibration reduction technology, the multi-layer structure has been widely concerned by scholars0.
In order to check the accuracy and reliability of the measured data, firstly the relationship between the complex modulus of the measured data and the loss factor is drawn, as shown in Figure 6, in which the horizontal coordinates represent the logarithmic of complex modulus and longitudinal coordinates represent the loss factor.
The curve presents inverted U shape, which indicates the dispersion of the data has meet the basic requirements.

By definition, data is an item which has not yet been performed.
Only the contextualization of data shall deliver added value for the creation of information, provide support for data interpretation.
In particular, the information makes connections between different data to define a fact.
The information thus involves some understanding of the relationship that exists between data.
Therefore, information can be comes from the link that exist between more data.
