When transmitting information and control signals to electrical, electromechanical and mechatronic systems are require reduction to the lowest possible levels of noise interference. For this is substantiated in the general formulation of the one-dimensional problem of determining the sensitivity of a...

Different problems arising in system analysis and design need building system models describing their internal structure. Graph representation that is commonly used in this case allows to present system structure only as a set of related components. For reflecting specific structural properties of modeling...

The modified D m si's cryptosystem [1] is a stream cipher based on deterministic finite automata without outputs for encoding and decoding. This cryptosystem uses an additional control system to improve the performance to a better linear time without backtracking. This paper, we propose a nondeterministic...

The contribution of the of voltage drop components to the impedance of the plasma gap was analyzed based on the non-stationary models of processes in low temperature cesium plasma. Depending on the phase of the plasma parameters and the properties of the thermionic energy converter the voltage drop components...

This paper considers method of Cauchy problem solution for nonlinear differential equation. Source of solution error and way of eliminating it is studied. Solution obtained with suggested method is compared with solution obtained with built-in MATLAB functions.

CUSUM algorithm for controlling chain state switching in the Markov modulated Poisson process was investigated via simulation. Recommendations concerning the parameter choice were given subject to characteristics of the process. Procedure of the process parameter estimation was described.

Decision trees have been recognized as interpretable, efficient, problem independent and scalable architectures. In case of fuzzy representation there is no procedure of automation tree building. In other words existing approaches of building decision trees and fuzzy decision trees cannot provide automatically...

During the last seven years Samara State Aerospace University performs an educational strategy for engineers and masters programs in aircraft engineering. The goal of the strategy is to formalize procedures and operations within airplane designing activities, in particular, the preliminary airplane design....

This paper presents a mathematical modeling of the plasma generation in a hollow cathode and the diffusion saturation of metals and alloys by nitrogen atoms in the plasma of a low-pressure non-self-sustained glow discharge. Characteristics of gas discharge are obtained. The relations between main technological...

Under current conditions it is impossible to manage a company to a good quality without specialized instruments. Currently decision support systems (DSS) are widely used to manage the bankruptcy risks of a company. Developing a DSS requires proper mathematical models. It allows return on capital forecasting...

Nowadays computed tomography provides the possibility to image internal cellular structures of embryos. A major challenge is a high accuracy image segmentation of tissues and individual cells. The process of manual image segmentation is time consuming and error prone. It can be partially replaced or...

This paper describes a multi-agent system for monitoring, diagnosis and forecasting the technical system condition with the car as an example. The system consists of four agents: the monitoring agent (collects reports on the condition of the vehicle, handles requests from the user and displays the response),...

To effective use of low-energy electron beams for technological purposes it is necessary to transport them to the target. For this a previously created plasma channel is used or the beam is injected in a neutral gas and creates independently the plasma channel. A longitudinal external magnetic field...

Objectives: Of the research was to identify the most informative criteria of progression of chronic mercury intoxication and the possibility of its prediction using neuropsychological and neurophysiological methods. Material and Methods: For research were chosen 3 groups of patients with different degrees...

The paper deals with the verification of manuals using ontologies built using ontological editor Fluent Editor. The ontological editor Fluent Editor creation of ontologies by using Controlled Natural Languages (CNL), which is close to a natural language that simplifies and facilitates the user's work....

The basic principles of quantum mechanics of the photon, describing its single-particle states by means of the wave function in the coordinate representation are given. This wave function is a wave packet constructed by the superposition of the basic bivectors which are eigenfunctions of the operators...

The article proposes the modified Kriging method for synthesis of three-dimensional model of geoenvironmental parameters based on data of land and borehole seismic survey

This paper reviews an inverse problem of spectral analysis of the Dirichlet's boundary value problem for Laplace operator with potential in a bounded domain .

It is offered to use the office of fuzzy graphs for modeling of problem oriented systems. The concepts of fuzzy transitive closure, fuzzy reciprocal transitive closure, and vitality degree of fuzzy graph are considered here. The algorithm for finding the vitality degree of fuzzy graph is described. Presented...
