The R-squared values represents the amount of variation in the data.
The reduction of SnO2 NWs diameters could be attributed to the amount of growth species.

The quantitative ratio of monolithic and large-panel residential buildings constructed for the period of 2005-2018 according to the data of large construction companies in Armenia The main feature of monolithic construction is that the place for the installation of formwork, reinforcement, as well as the formation, compaction and hardening of concrete structures of the building is the construction site.
This leads to a significant reduction in the timing and cost of construction, as well as provides quality construction without the use of expensive additional seasonal measures.
This method provides year-round quality construction without the use of expensive additional measures of cold winter and hot summer concreting, is not vulnerable and leads to a significant reduction in the timing and cost of construction on the construction site and the cost of housing.

This ratio increases with improved homogeneity of the concrete’s micro- and macrostructure and a reduction in defects that promote stress concentration.
After processing and statistical analysis of the obtained experimental data, experimental-statistical models for compressive and flexural tensile strength of the fiber-reinforced concretes were constructed, as shown below: Experimental-statistical model for compressive strength: (1) Experimental-statistical model for flexural tensile strength: (2) It should be noted that to achieve the required workability, mixtures with higher fiber content required increased water dosage.
The reduction in concrete plasticity is attributed to the increased surface area, which requires more cement paste, with the effect of polypropylene fiber being more pronounced.

The data correspond to high temperature soaking conditions (1400-1460ºC), i.e. a high degree of microalloying element dissolution, and 30 s interpass time [[] R.
This decrease will be due to a reduction of the Nb content in solution (part of Nb precipitated before rolling as (Nb,Ti)(C,N) particles) that will decrease the solute drag effect but also delay the start of strain induced precipitation and also to Nb(C,N) co-precipitation onto TiN coarse particles.
This definition, in addition to the chemical composition and total reduction to be done in the rolling mill, will also depend on the steelmaking and post-solidification step conditions prior to hot rolling.

After that, the viscosity index (VI) value was calculated according to ASTM D2270 by using the measured data of kinematic viscosity at 40 °C and 100 °C.
The result clearly indicates that MRPO5 presented the smallest WSD at 639 µm from the MRPO samples and had a 3 % reduction compared to RPO.
This indicates that the VI of MRPO2, which is higher than SE, significantly reflected on the reduction of COF value.

The data were collected until 1000 °C.
This can be confirmed by the size of test casting for the hypereutectic conditions that are larger than the mold cavity by +0.17% where all other conditions showed the size reduction up to -1.46%.
All testing castings showed the size reduction (measured at room temperature) ranging from -0.40 to -1.44% except the hypereutectic compositions which showed the swelling (+0.03 to +0.17%).

The performed theoretically analysis is compared with the experimental reported data.
Saunders have proposed that the improved efficiency of a hybrid ETA solar cell needs the efficient charge separation and reduction of effective series resistance by increasing interface area of the nanoparticles and the p-type materials.
The electrons and holes are used in separate reduction and oxidation reactions at the TiO2 surface, so extending the lifetime of each charge carrier is vitally important to improving the efficiency of TiO2 as a functional photocatalyst [17].

Let the dependent variable data be reference sequence Y and each variable data be comparative sequence Xi (i = 1, 2, 3, …, n).
Each variable data has different units, and therefore it is necessary to conduct dimensionless process on the sample data sequence to obtain new normalized sequence: X’=（X1’ , X2’ , ,···，Xn’) (3) Calculate the difference sequence of each time.
Class ratio test refers to conducting the feasibility test of the original data sequence for GM (1,1) modeling.
The sample range in this paper is 1991 – 2012, and the data to be used are from the China Statistical Yearbook.
Then conduct gray correlation analysis based on the data in Table 3 with the results as shown in Table 4.

However, the dimensioning and design of joints and suitable processes are mainly based on expert knowledge and few experimental data.
Therefore, data-based methods provide high potentials for the optimization of target features [3].
Subsequently, an algorithm can read out all relevant geometric information that is stored within the nodes’ meta-data.
The use of a clustering algorithm showed satisfying results in the classification of the generated contour data.
The approach thus paves the way to the data-driven design of mechanical joints.

Five drying models were evaluated for the thin-layer data.
They were therefore fitted to the experimental data for sesame seed drying in the current study.
The change of the grain moisture content, with time, was calculated from the mass change data.
Therefore, for further analysis of data, only Page’s equation was used.
