Lossy image compression is a popular way to get higher compression ratio, it also has several peculiarities if one deals with compressing images corrupted by noise. First, a specific noise filtering effect is observed. Second, optimal operational point (OOP) might exist where quality of a compressed image is closer to the corresponding noise-free image according to a chosen quality metric. In this case, it is worth compressing this image in OOP area. These peculiarities have been earlier mainly studied for grayscale images. In this paper, we analyze compression of color images corrupted by additive white Gaussian noise using better portable graphics (BPG) encoder in the cases of different chroma subsampling. Based on simulation results obtained for a set of color images, the initial recommendations on encoder parameter setting are given.

The work is dedicated to the development of the system to define the credibility of text messages posted in Telegram newsfeeds. The topicality of the work is stipulated by the concentration of information and its ability to influence shaping of the social opinions on the state relations and political moods via news feeds in messengers and social networks, the number of which is constantly growing and supported by bots and biased authors. The proposed system functions on the basis of coordination of text parsing, text processing, database with messages from the official sources of information, and the client (author) database. The degree of similarity of the generated text messages is determined on the basis of defining Damerau-Levenshtein distance in the Text Processing Module. The work shows it is possible to increase the efficiency (up to 1,44 times for messages of around 1500 symbols) of the given module performance through incoming messages stemming at the preprocessing stage because this enables to reduce the computational complexity of Damerau-Levenshtein method at the expense of word shortening to their stem via neglecting auxiliary parts such as suffixes and endings. Thus, stemming helps to reduce the amount of symbols to be processed at the very stage of Damera u-Levenshtein algorithm application, which proves feasibily of applying stemming in the preprocessing block.

The article shows the possibility of autonomous induction generator operation with a resistive load. Self-excitation of the induction generator is carried out by a single capacitor. A load is switched on between two phases of the generator stator winding. Active power regulation in an induction generator is possible by changing the capacitance of the capacitor, the resistance of the resistive load, and the rotor speed. Power control is possible in a relatively narrow range of rotor speed and load current.

The purpose of the study was to verify the previously created methodology for designing electromechanical systems. This methodology is based on SysML language and artificial intelligence tools such as conceptual graphs and Bayesian networks, and involves the construction of an information design model that contains knowledge about the requirements for the system being designed and a knowledge base of available technical solutions. Further, such an information model is used for automatic logical inference of technical solutions according to the requirements specified by the designer. The proposed methods and tools for design automation make it possible to trace the requirements for electromechanical systems at all stages of design, and evaluate the robustness of technical solutions to changes in these requirements. For quick and efficient implementation of the proposed methodology in the practice of industrial design, it must be verified by evaluating the degree of efficiency, completeness, consistency and feasibility of the synthesized design solutions, the convenience of using artificial intelligence tools in the course of solving typical industrial equipment design problems. For this purpose, a configurable laboratory stand was built, which is a physical model of a simple workcell of an industrial manufacturing system. The stand performs the typical functions of a workpieces sorter, has a modular design, and can include the implementation of specified functional requirements by various technical means. Thus, it is possible to obtain different configurations of the sorting device having differences in the sequence of operations and technical properties. To automate the design of these configurations using the CoGui software tool, an information model was created that compares the possible system requirements for the stand with suitable variants of technical solutions. This model is used to automatically obtain descriptions of stand configurations. The performance and other properties of the resulting configurations were then tested on the operating equipment of the stand.

Distance relays for protection of power transmission lines used, which can be based on fixed stings Adjusted. But usually, the amplitude of operation of these relays changes with changing network conditions (network topology, load value, output value, etc.) and causes the relay to malfunction, using methods that can process information and pattern recognition, such as the use of fine processors and intelligent algorithms can use new relays that have high accuracy and thus achieve proper protection. In this paper, a distance relay is simulated by a neural network and it is observed that the neural relay has higher accuracy than a normal relay. In addition to fault detection and location, the type and phase of the fault can perform simultaneous protection of three phases. As a result, the number of line relays can be reduced by using neural relays. The MLP neural network is used to simulate the distance relay.

Analytical and numerical-analytical methods for simulating a plane axisymmetric contact behavior of an elastic pipeline section with an isotropic or orthotropic viscoelastic composite wrap considering the features of its mounting on a loaded or unloaded pipeline with or without tension have been developed. These methods allow analyzing the efficiency of repair works on different mounting modes and at various degrees of anisotropy of the viscoelasticity of the composite wrap. The methodology qualitatively differs from the previously created techniques by a complexity of the approach, a high speed, an automation of receiving the sought-for parameters and a possibility of the created models to consider the degree of anisotropy of viscoelasticity which differs from the degree of anisotropy of elastic properties. These advantages of the simulation model allow using it in the further computational intelligence algorithms as a standalone or integral part.

The paper deals with the development of mathematical backgrounds to transform dynamical system into the generalized time domain. This transformation allows to change the trajectory of the dynamical system's motion and gives to dynamical system new properties and features. One of such features is the possibility to form motion trajectories with identical anterior and posterior fronts. This feature gives us the possibility to improve system performance and accuracy and we consider system motion in direct and inverse time to ensure it. We study different time domains and define transformation functions to perform the transition from the one time domain into another one. As a result of our studies, we define generalized transformation factor and patterns in its determining, which usage makes it possible to rewrite the differential equation of the considered dynamical system into desired time domain without applying any transformation routines and defining any transformation functions. The implementation of our approach brings us to consider variable structure dynamical system which has an identical start and stop trajectories.

This paper is devoted to analysis of liquid vibrations in rigid containers at seismic loads. An effective numerical method is developed involving boundary elements and fuzzy logics. The novelty of the proposed method consists in using fuzzy concepts to analyzing uncertainties in earthquake parameters. First, deterministic methods are used for estimation of dynamic characteristics of structures with compartments partially filled with liquids. Sloshing problems are solved both in linear and nonlinear formulations. Then randomness of some earthquake parameters is adding to mathematical model. The fuzzy stochastic differential equations are received and solved numerically. Numerical results are obtained that demonstrate influence of uncertainties. These results provide a more adequate estimate of the free surface level during earthquakes and allow us to draw a conclusion about the possibility of hazardous contents spilling.

The purpose of the article is to offer the method tool, the characteristic estimates, the theoretical analysis of the ongoing electrodynamic processes and the experimental testing aimed at substantiating the efficiency of magnetic-pulsed separation of two flat tightly adjacent conductive sheets in an inductor system with a rectangular solenoid placed on one of their surfaces. Methodology. For conducting the research, the methods for solving boundary electrodynamics tasks, the mathematical applications from the Wolfram Mathematica package, the experimental research methods in Mechanics and Applied Electrodynamics have been employed. Results. The analytical expressions for the spatiotemporal distribution of magnetic pressure forces in rectangular inductor systems which generate packets of low-frequency plane-parallel electromagnetic waves have been obtained. Successful experimental testing of the magnetic-pulsed separation of aluminum sheet samples confirmed the validity of theoretical conclusions. It was found that for the practical application of this production operation, sufficiently small values of exciting fields, as well as low voltage values on the capacitive energy storage of electromagnetic power sources $(sim 0.5ldots 1 text{kV})$ are required. Practical implications. The results obtained allow to put into practice effective magnetic-pulsed technologies of separating sheet metals in automated lines and their transportation directly to the processing zone.
