Statistical processing of the data was performed using the software package STATISTICA.
Finally, there may be changes at the level of the capillary network, including a reduction in the density of arterioles and capillaries within a given vascular bed [12].
Our data are consistent with the results of I.E.Chazova et al. [13] and B.V.Mychka et al. [14] who observed deterioration of cerebral perfusion in the parietal areas and adjacent departments - parietal-occipital, fronto-parietal and temporo-parietal in the presence of AH.
In such conditions, AH reduction for any reason, including the circadian oscillations leads to hypoperfusion in the areas of terminal blood circulation.

Composite sheets of 60 mm × 50 mm × 5 mm dimensions were rolled for 50% reduction (a true strain of ~0.7) in multiple passes with about 1% reduction per pass to avoid adiabatic heating.
At each test condition, three specimens were tested with each data point representing the mean of three tests.
The quantitative data on the intensities of different peaks, normalized to that of the most intense peak, recorded on the Z-plane is shown in Table 2.
Niranjani et al. performed RT and LN rolling on a modified version of AA6061 alloy to ~80% reduction and tensile tests revealed similar level of yield strengths and low ductility at both the temperatures.
In contrast, the RT rolled samples in the present study exhibited a 70 % increase in tensile strength with a reduction in the ductility, which is due to the phenomenon of strain hardening.

VGStudio MAX software was used for CT data analysis.
It was used only for 5 minutes to avoid thickness reduction and maintaining structural integrity.
To obtain the 3D deviation analysis (Fig. 5.b), a comparison analysis between the nominal CAD (orange colour in Fig. 5.a) and the 3D CT data set (grey colour in Fig. 5.a) have been performed.
Regarding warming up during operation, a reduction of 15 °C has been achieved when comparing the conventional case with the AM solution and 30 °C if introducing force air.
Regarding the weight of the component, by using AM case with internal channels, a reduction of 37% has been achieved.

All of the data was then sent to a data acquisition computer for
analysis.
The substantial reduction in the specific energy by cryogenic cooling can be attributed mainly to the retention of the sharpness of the grits due to laeese wear and plastic deformation an decrease temperature.
This could be attributed to more reduction in grinding forces under cryogenic cooling at higher depth of cut.
The measurement results show that the profile longitudinal parameter values, such as Ry、Rq、Ra and Rz reduction of about 30%~50% in comparation with the oil-based coolant.
A reduction of about 30%~ 50% of the longitudinal parameter values could be realized by the application of the liquid nitrogen grinding the nickel based superalloy.

Aim of this work is to investigate the potential advantages
of employing data sonification strategies during the real-time process of data collection.
The results obtained show that the proposed technique can result into an eye-free, efficient annotation of the most significant time intervals of the overall monitoring process, allowing for the reduction of the amount of data that will be further processed by the core monitoring model.

Average grains intercept of ZTA with various amount of binder
Density data for ZTA with different amount of PVA is shown in Fig. 4.
From the data, ZTA composite with the addition of PVA has slightly decrease in density from 3.34 g/cm3 to 3.02 g/cm3 when more PVA is added from 1 wt. % to 5 wt. %.
Therefore, the average grain intercept data shown in Fig. 3 support this density data where the value of AGI of the sample with 4 wt. % of PVA is the lowest.
This density data shows an increase in density compared to the density data shown in Fig. 4.Even the composite without binder showing an increase from 3.438 g/cm3 (0 wt. % PEG-no carbon) to 4.044 g/cm3 (0 wt. % PEG-carbon).
This can be supported by the microstructure in Fig. 9 and AGI data in Fig. 10.

This class contains statistical methods designed for analyzing high-dimensional data using low-dimensional projections [4].
In 1936, Fisher’s linear discriminant analysis on IRIS data is the essence of projection pursuit clustering method.
Switze applied the technology to have a classification of fossil data, and this form the early projection pursuit clustering ideas [5].
Referring to the Statistical Yearbook, we select 19 factors nearly 16 years of statistical data as a sample.
Conclusions The existing problem of serious multi-collinearity in Predictive factors are complicated and interactive, Partial Least-Square Regression have advantage in data structure reduction, in this study, we extract two independent components to solve the collinearity of independent variable factors, and through dimension reduction to Solve the Non-Linear Problem.

There is no adequate accumulated on-site test data, especially the on stress test, so the application of RPCF in high-rise buildings is restricted to a certain degree.
Based upon the test and test data, this article analyzes and discusses the load-carrying characteristic and bearing mechanism of RPCF of high-rise buildings.
Fig. 3 indicates the ratio of settlement of soil among piles under equipollent load to undisturbed soil reduction.
In view of good soil condition in this test, the reduction coefficient should be properly lowered in general.
The figure shows that the fit curve is in good agreement with the measured data.

Experimental data was judged via angle, displacement and moment.
Then, we used a sensor data acquisition system based on the USB6211 data acquisition card to realize the rapid collection and display of angle, displacement and moment data.
Data and statistical analysis.
Concerning 2-ACDF, fusion caused reduction of ROM at C23 and increase of ROM at C7-T1 in most mechanical modes.
After 1-TDR, instrumented level (C45) had a biggest reduction of 25.16% in RB.

This contribution will review
some of the recent work on these and related materials and will present new data on
the La2MO4+δ (M= Ni, Co or Mn) systems.
In particular data on the oxide ion diffusivity of these systems, as determined by oxygen isotopic exchange and SIMS analysis highlighting the fast oxide ion diffusion (1 x 10 -7 cm 2s-1 at 750 oC) present, will be discussed and the significance of these data evaluated in relation to solid oxide fuel cell systems.
This is the basis for much of the data discussed in later sections.
Further data has been gathered on the Nd and Pr analogues, both as stoichiometric and cation non-stoichiometric systems.
