This represents a major problem in multiscale modeling of materials whose goal is to develop a systematic coarse-graining procedure through which the essential atomic-level details of the problem can be projected into macroscopic laws or continuum models.
Theoretical background In the following, we will discretize the simulated body into a finite number of mesoscopic cells (mesocells) that can contain from a few to thousands of unit cells.
Moreover, any mesocell may be either dislocation-free or contain a finite number of crystal dislocations.

The hot cracks occur at high temperature along the grain boundaries when the level of strain or strain rate exceed a certain level and it is connected with the technological strength of welded joins.
According to maximum principle function of power density qy,τ takes the following expression: qy,τ= qmax2+qmax2n=0pξnψn(y,τ,τ' where ψny,τ,τ'=e-aμn2τ'-τcosμny, τ'= abv,μn= πnl Unknown numbers ξ0,ξ1,...
Let the numbers ξ1(r),ξ2(r),…,ξp(r) are r-м approximation to the exact solution of the equations.

The concentration of each element isn’t necessarily equi-molar but it can be between 5% and 35% which allows the possibility of the number of high-entropy alloys systems to grow [10, 11].

The basic research question is that in multi-Agent system behavior modeling and coordination of relatively coarse-grained problem solver between the contents of the study involving distributed sensing, inter state prediction, architecture, fault diagnosis, Multi-Agent System, Agent communication and coordination, and so on.
After obtaining the information fusion system or device monitoring information, carried by a number of state recognition Agent troubleshooting and diagnostic analysis based on different methods and rules, the final decision by the diagnostic conclusions obtained information fusion process.
As shown, the input layer corresponds to a failure in which the phenomenon of the output layer corresponding to the cause of the fault,there are provided m the input layer nodes LA, LC output layer has n nodes, the number of nodes in the hidden layer LB u.

The coating surface was composed of grains with
different diameters, which are melted and unevenly distributed on the coating surface.
However, the number decreases to 470 HV after 60 min friction and wear test.
A number of adhesion tests were also performed.

In terms of the regions of the Republic of Armenia, Syunik province occupies the first place in the share of the urban population in the total population - 71%, which is conditioned by the number of cities: Kapan, Goris, Sisian, Meghri, Kajaran, Agarak, Dastakert.
The main proportions of the floor, openings, plan and layout dimensions were determined by the operational-realistic dimensions of the main building material (brick grain) (related to the dictation requirements of the mold strength).
There are a number of fundamental or nuanced differences in the totality of materials used in different cores of the same cluster: • Availability of straw • Brick / earth module / sizes • Color • Density • Composition The formation process of the architectural-spatial environments of Syunik, subjected to chronological analysis by the settlement, clearly distinguishes clusters of chronological, structural, residential districts and construction art.

The EVOH substrate was abraded with a sandpaper (SiC with an average grain size of 10 µm),
ultrasonically washed with acetone and ethanol, and then dried at 100°C under vacuum for 24 h.
After CaP treatment (Fig. 2, b), TEM image showed a number of particles newly deposited on the specimen surface.
The ACP particulate observed in Fig. 2 (b) disappeared, leaving a layer consisting of a large number of needle-like substances.

Due to the oriented grains of the cast carrots, only a few peaks were appeared in the bulk samples.
Table 1 shows the average size, number density and weight percent of the γ΄ precipitates under different cooling rates.
At higher cooling rates such as 15 ºC/min or air cooling, due to higher undercooling, an explosive nucleation has been occurred which has led to the higher number density as well as smaller precipitates.
According to Table 1, it is also observed that as the cooling rate is decreased, the size and weight percent of the γ΄ precipitates has increased as well as their number density has decreased.
