In the research the development of a mathematical model for predicting threats of information security of
Internet resources is carried out, which allows, based on the minimum amount of input data, to indicate
the dynamics ...
This article discusses the problems of today’s infocommunication networks, the basis of which are multiservice
networks serving all types of traffic, presented as a set of IP packets. The characteristic features of ...
Nowadays, much attention is paid to the creation of favorable conditions for the health and work of people
and the microclimate in the design and further operation of buildings. It is necessary to investigate the
processes ...
The mathematical model of apples shock interaction with each other and with working surfaces of technological equipment during their gathering, transportation and technological processing has been presented. In the model ...
There has been analytically solved the problem of determining the stress state in the cross section of bending
reinforced concrete beams with a crack in a linear formulation. For this, the beam is cut along the crack
line ...
A mathematical model of root crops after-cleaning and their movement pattern in a technological run for
loading into means of transportation has been presented. The impact of both controlled and uncontrolled
factors on ...
In given work are considered model-theoretical properties of companions of (n1; n2)-Jonsson theory. Also
were considered a communications between center and (n1; n2)-Jonsson theory. Herewith considered theories

main ...
In this paper we investigate a class of loaded ordinary differential equations with nonlocal integral boundary
conditions in terms of an abstract operator equation
Bu = A2u q (u) = f; f 2 Y; (1)
D(B) = fu 2 D(A2) : ...
An nonhomogeneous integral equation with a singular kernel is considered. A feature of the equation under
study is the incompressibility of the integral operator. In the study of the equation, an auxiliary simpler
equation ...
In the paper the question about distribution of eigenvalues of third-order composite type equations with
regular, more precisely, with periodic boundary value conditions is studied. After, applying the Fourier
method, ...
The paper studies a loaded hyperbolic equation with one-dimensional wave equation in its main part. In
the loaded components there are two points, which are distributed respectively along a pair of intersecting
characteristics ...
The article is devoted to the research of boundary value problems for the spectrum - loaded operator of
heat conduction with the moving point of loading to the temporary axle in zero or on infinity. For strongly
loaded ...
In the article mathematical modeling of the solution of the static Stokes problem is considered by solving
the static problem of the theory of elasticity, with Hooke’s law. We obtain estimates for the proximity of
solutions ...
