USE OF A NUMERICAL ANALYTICAL MODEL FOR ASSESSING THE FUNCTIONAL EFFECTIVENESS OF AN INFORMATION PROTECTION SYSTEM BY ANALYSING ITS PROBABILISTIC-TEMPORAL CHARACTERISTICS

open access: yesВестник Дагестанского государственного технического университета: Технические науки, 2020
. Aim Currently, the implementation of computational experiments to determine the probabilistic-temporal characteristics of protection functions for automated information systems is a complex and costly task. In order to study the dynamics of transitions

Calculation of the decomposition coefficients for plane contact problem kernel in the orthonormal basis

open access: yesApplied and Computational Mechanics
Analytical solutions of some contact problems are infinite functional series according to the system of basic functions. When constructing such solutions, it becomes necessary to represent the kernels of integral equations describing the process of ...

The Dirichlet problem for complex Monge–Ampère equations and regularity of the pluri-complex Green function [PDF]

open access: yesCommunications in Analysis and Geometry, 1998
Regularity property are studied for solutions of the Dirichlet problem \[ (dd^c u)^n= \psi(z,u,\nabla u) \quad\text{in }\Omega, \qquad u=\varphi\quad\text{on }\partial\Omega, \tag{1} \] \(\Omega\) being a bounded domain in \(\mathbb{C}^n\) with \(C^\infty\) boundary. The main results obtained are as follows. Theorem 1.1.

The inhomogeneous complex partial differential equations for bi-polyanalytic functions

open access: yesAIMS Mathematics
<abstract><p>In this paper, we study a Riemann-Hilbert problem related to inhomogeneous complex partial differential operators of higher order on the unit disk. Applying the Cauchy-Pompeiu formula, we find out the solvable conditions and obtain the representation of the solutions.

Discrete Sequential Information Coding: Heteroclinic Cognitive Dynamics

open access: yesFrontiers in Computational Neuroscience, 2018
Discrete sequential information coding is a key mechanism that transforms complex cognitive brain activity into a low-dimensional dynamical process based on the sequential switching among finite numbers of patterns.

Assessing lateral flows and solute transport during floods in a conduit-flow-dominated karst system using the inverse problem for the advection–diffusion equation [PDF]

open access: yesHydrology and Earth System Sciences, 2017
The aim of this study is to present a framework that provides new ways to characterize the spatio-temporal variability of lateral exchanges for water flow and solute transport in a karst conduit network during flood events, treating both the diffusive ...
