GLOBAL MARKET FORECAST NANOPOWDERS
We have made a global analysis of the market nanopowders. Based on the available data it can be concluded that the introduction of nano-powders in various spheres of high technologies will occur every year more intensive...
THE TRICOMI PROBLEM FOR A THIRD ORDER HYPERBOLIC EQUATION DEGENERATING INSIDE THE DOMAIN
In this paper, we study the Tricomi problem for a third-order hyperbolic equation with degeneracy of order inside a mixed domain. The existence and uniqueness theorem for a regular solution is proved.
A PRIORI ESTIMATES OF THE SOLUTION BOUNDARY VALUE PROBLEMS FOR THE CONVECTION-DIFFUSION EQUATION OF FRACTIONAL ORDER
In this paper, the method of energy inequalities obtained a priori estimates of the first and third boundary value problems for the convection-diffusion equation of fractional order, from which follows the uniqueness and...
APPLICATION OF A LOGICAL NEURAL NETWORK TO THE CLASSIFICATION PROBLEM
The solution of the classification problem is becoming more urgent due to the development of technology and the growth of the processed data volumes. The use of neural networks is mandatory when solving classification pr...
