The results of the indentation problem solution are in good agreement with experimental data.
The results of the numerical solution demonstrated good agreement with the data obtained from the experiment which was carried out at the kinematic loading fixture.
The experimental data are given in the form of the dependence of the magnitude of the force applied to the stamp from the penetration depth .
The comparison of calculated curves with experimental data shows that up to a relative depth of penetration equal to , which corresponds to deformations about 15%, the experimental data are well described both by tensor linear relations Eq. 7 and by physically nonlinear relations Eq. 11.
The numerical aspects of the model implementation are considered in detail, and its verification is carried out by comparison with the obtained experimental data.

The paper presents composition of innovative material used for corrosion protection of reinforced concrete structures and experimental data on the increase in cracking of reinforced concrete elements coated with polymer-cement protective layer against corrosive media.
The study resulted in experimental data on the element load-carrying capability, relative level of crack formation, deflection growth with load increase, and plotting of the "moment-bending" diagram for all elements.
Reduction of peak stresses in weak points of concrete with the help of the polymer layer. 3.
All the above factors explain the nature of the crack resistance improvement effect and are used in the review of experimental data and calculated conditions.
As a result of studies, we obtained experimental data on load-carrying capacity of the elements, relative level of cracks formation, growth of deflection with load increase.

Meanwhile, poly rod used has lower price and easier fabrication, so CFZ-Si cost is much lower and the further cost reduction is easy.
Figure 2 Resistivity change along axial direction of CZ-Si and CFZ-Si The specific testing data about the aspects above is in table 1.

According to data about GIS breakdown maintenance in Maintenance Branch of State Grid Chongqing Electric Power Company during recent years, GIS accident of Chongqing Electric Power Company that happens every year is internal fault of local air chambers (such as breaker, PT and bus) in most cases.
As a result, bad consequences like corrosion and reduction of insulating property will be caused.

On basis of the data and analysis, two conclusions are drawn: (1) Installation of baffles exerts high influence on heat transfer characteristics of the heat exchanger studied. (2) The reason why the baffles could exert such influence is that the baffles prevent much air from flowing into external zones of the baffles, so in per unit time more air exchanges heat energy with hot walls of heat exchange tubes, which are in internal zones of the baffles.

Let denote the average length of retransmitted data within .
Because of retransmission, the actual transmitted data length is
During the sensing window twin, no SU data is delivered.
Usually, when the number of erroneous received data exceeds a threshold, retransmission is initiated.
Especially, the retransmission of SU data is considered.

Section 2 introduces several data structures involved in our method.
Data structure Several kinds of data, topographic and geomorphological data, meteorological data, and regional geographic, social and economic data, are involved in our method.
Meteorological data includes mainly precipitation data of many precipitation gages from 1967 to 2006, maximum 3-day precipitation data selected in the study area.
Regional geographic data is used for determining the scope of the study area and interior county-level division, social and economic data comprise of population, GDP, output values of primary industry, secondary industry and tertiary industry in 2001 and 2008.
Precipitation Through meteorologic data in the study area, there is no instinct difference between maximal 1-day and three-day precipitation, therefore, the data was not considered in the study.

The data analysis is based on conceptions of the texture
formation theory, connecting features of grain reorientation with activated deformation
mechanisms.
Computer data treatment was carried out by the program complex, elaborated in MEPhI.
In more details the procedures of GPF measurement and data treatment are described in [1-2].
In particular, there are two main interconnected aspects, which can be considered in details on the basis of extensive data, obtained for rolled g-Zr - principles of texture development and acting deformation mechanisms.
Experimental data, obtained by the X-ray GPF method, describe the substructure condition of ECAP rods from Zr in details.

Methodology
Data collection.
Descriptive statistics depicted the features of the product or production methodology from the data collected, whereas inductive statistics generated conclusions from parameters derived using the collected sample data.
Descriptive statistics solely discuss the feature of the data; instead of analyze the data on a larger scope.
It was a data reduction and data summarization method using mathematics to compress numerous variables into few essential ones.
By adopting descriptive statistics to analyze the scoring data of policy conduct and practical conduct in the 25 local regions, it would be the initial analysis of the data itself. 1.

The study also observed a shift from shear-thickening to shear-thinning behaviour and reduction in thixotropic properties with increased dosages of the admixtures, which is beneficial for 3D printing.
Rheological measurements of the pastes were performed by means of a Discovery HR-1 (TA Instruments) hybrid rheometer and TRIOS 4.1.1 software was used for data evaluation.
