Each experimental run included a minimum of 5 replicates, with the key data of tensile modulus and tensile strength presented as average values and standard deviations.
Specifically, SW40 exhibited a 50% reduction in tensile strength compared to pure PBAT.
A reduction in the tensile strength of the composites may be correlated with the early failure of the samples, which is anticipated when rigid particles are integrated into the polymer matrix.

In contrast, the activation energy values in the three doped Al2O3 are 750-830 kJ/mol, which are about twice as large as the activation energy in undoped Al2O3 and even larger than the reported activation energy data for lattice diffusion of Al3+ or O 2- ions [10,11].
The marked reduction in creep strain rate with cation doping results from cations segregation in grain boundaries probably due to the suppression of grain boundary diffusion.
However our recent analysis on the codoping effect in Al2O3 revealed that the creep rate or grain boundary dittusiviy cannot be explained from the product of net charge values in contrast to the data of Figure 5.
BaTiO3 containing a suitable amount of BaZrO3 for example, has an extremely high and fairly flat peak values of dielectric constant near room temperature due to the reduction in the transition temperature.

To illustrate the methodology, we used data from the dabancheng wind farm, Xinjiang.
Wake effect reduction factor is:
According to the data of measured wind speed and wind direction, the wake effect reduction coefficient is K=3.022%.

Many experimental studies and analytical on the geothermal exchanger are available in literature: Francis [3] presented experimental data showing the performance of earth cooling tube system in the Midwest Region of the USA.
Additionally, the weather data, radiation processor and sky temperature TRNSYS types [11] were incorporated to the complete modeling task.
In fact, by using tube length more than 60 m, the cooling energy reduction will be negligible; - Regarding tube depth, a good compromise between energy performance and excavation costs is preferable with a depth of about 2 m; - Air flow rate of 200 m3/h is recommended when the efficiency of the system is 85% Finally, in summer conditions, EAHE with nocturne ventilation and mass inertia of walls have been coupled and simulated to evaluate indoor thermal comfort conditions.
A reduction of the internal temperature of 5°C has been found.

WQI is a mathematical method to transform large quantities of water characterization data into a single number which represents water quality classification.
This reduction is caused by passing the river through populated centers and entrance of waste water to the river.

According to the data on particle size distribution of the cement used in the experiments, fractions Ø1, Ø5, Ø10, Ø20 and Ø60 µm constituted 4.75, 18.58, 31.62 and 85.56%, respectively, and the grain sizes D10, D50 and D90 corresponded to 2.13, 20.5, and 69.7 µm.
According to X-ray spectra microanalysis data, the alkalis are mainly concentrated on external hydration products.
At the early period of structure formation, a considerable reduction of calcium and sodium ion concentrations took place, what is connected with the formation of the phase 4CaO·0.9Al2O3·1.1SО3·0.5Na2O·16H2O.
The alkali-sulfate activated blended cements are very promising from the point of view of energy saving in concrete production and reduction of CO2 (by 1.46 times lower CO2 emissions compared to CEM I).

The driving force for grain growth results from the decrease in the free energy associated with the reduction in total grain boundary energy.
Data corresponding to steels from the work of Palmiere et al and Cuddy et al have similar amount of Ceq=0.07-0.09 and were obtained after heating for 30 minutes at the corresponding austenitizing temperature.
The discrepancy observed in Fig. 5 between data by Gladman et al and the other authors is probably due to the difference in the size of carbonitrides.

Access to data is the first step in reverse engineering, and only accurate three-dimensional surface data to complete reverse engineering.
As the object of data collection sample, measured data fitted surface does not directly as a mold punch and die, or core, cavity model, CAD systems often use these data to be modified.
Use of coordinate measuring machines and laser scanning data obtained are scattered cloud data, there is usually a large random error.
The rules of cloud data into an ordered data set of quadrilateral mesh, easy to shape the formation of many pieces of data blocks.
a) Construction and analysis of the curve Smooth curve through the point data reduction and screening, the curve will be a "jitter" phenomenon.
