The article is devoted to solving the problem of the combined control law synthesis for one class of non-affine plants with a delay in the input variable. The considered plant operates under conditions of a priori parametric and structural uncertainties in the presence of permanent external noise. Only the scalar plant output is available for direct measurement. The structure of the control system includes a reference predictor and dynamic filter-corrector. The synthesis of the combined regulator is based on the use of the hyperstability criterion, and the required operation quality of the obtained system is ensured at the stage of simulation.

Matching load modes of the drives of the top and bottom rolls of rolling mill stands is an important scientific and practical problem. Solving it is relevant for the drives of reversing stands of modern plate mills. The solution complexity is caused by the need for matching load balancing mode with the mode of forming a bend of the head end of the strip plate at the stand outlet. The oscillograms of the speeds and torques of the top and bottom roll drives have been analyzed for the existing drive control algorithm. The double or more difference in the drive torques in roughing passes has been confirmed. Thereat, the bottom roll drive torque reaches the limiting level, and the top roll drive switches to the generator mode. A technique for matching the modes of the upward bending and the drive load distribution systems has been proposed. A control technique has been developed, ensuring a forced matching of speeds. The diagram of an adaptive load-distributing controller is given. The oscillograms of the drive torques have been analyzed for the technique developed. Conclusions have been made on improving the accuracy and reducing the time for matching the torques. Information is given on the technical effect of implementing the developed technique on a 5000 plate mill.

We explore the problem of evaluating the practical effectiveness of hidden signal transmission under chaotic carrier. As a signal carrier we use the Shimizu-Morioka chaotic oscillation generator. The useful signal is embedded into chaotic carrier by nonlinear modulation on chaotic generator parameters. The problem is to detect a steganography property for chaotic system nonlinear parametric modulation. The pseudo-random signal in the communication channel is analyzed for the presence of a mixed useful signal in it by Fourier series and by method of autocorrelation. The conclusion about the steganography of the method of hidden information transfer is given. The presented study is a part of chaotic carrier data transmission system design approach with useful signal reconstruction at receiver side by using nonlinear synergetic state observer developed in our previous publications.

A methodology has been developed for optimizing the identification and processing of images of pollen grains based on the use of mechanisms for extracting texture, specific characteristics, and geometric features of micro-objects. A technique is proposed for the trend description of the contour according to the characteristics of the growth of a dynamic curve based on a wide range of functional dependencies. Extrapolation mechanisms have been developed for exponential, autoregressive, moving average, adaptive smoothing, statistical models of forecasting and linking of reference points of the image contour. The principles of masking reference points, pixel representation, adjusting their width, modifying biquadratic interpolation, as well as mechanisms for segmenting and detecting changes in the dynamics of the contour curve are proposed. The mechanisms for describing a contour curve by an interpolation spline - the Daubechies function, 4, 8 orthogonal polynomials in order to identify the characteristics of pollen grains - are investigated. A set of programs has been implemented that focuses on the application of a mechanism for reducing zero points, regulating the beginning, center, segment boundaries, mask width of the reference point, and color-brightness picture. The program modules of the complex are created in C++ and tested in the «CUDA parallel computing environment.

This article addresses the development of the system for automated incident management based on open-source software. The idea behind that research is to automate the information security incident management process, including reducing the processing time and incident response. Solutions of the Security Orchestration, Automation, and Response (SOAR) class were analyzed. Based on this analysis, the system for automated incident management has been developed. For the system to work without interruptions, a fault-tolerant operation scheme was designed. The system also implements centralized management with a distributed, federated architecture. This research confirmed that SOAR solutions can reduce incident response times, reduce the number of specialists in the incident management process, and automate this process.

In this paper, we examine the issue of video-based facial emotion recognition algorithms which show excellent performance on some benchmarks, but have much worse accuracy in practical applications. For example, the typical error rate of contemporary deep neural networks on the RAVDESS dataset is less than 5%. We argue that such results are obtained only if the split of the whole dataset is incorrect, so that the same persons are present in both training and test sets. It is claimed that it is more frankly to use the actor-based split, in which persons in the training and test sets are disjoint. It is experimentally demonstrated that the near state-of-the-art neural network model pre-trained on the AffectNet dataset achieves 99% accuracy on conventional split of the RAVDESS dataset. However, when we split the dataset by the actors and training and testing sets have only unique persons then the accuracy will be 20-30% lower.

Underwater vehicles used for surveys and inspections are equipped with computer vision systems based on video cameras. The efficiency of such underwater vehicles depends on the onboard software used, the development of which must take into account the peculiarities of operating conditions. The separate system’s test of the underwater vehicle can be used as a simulation of the conditions for its operation. The model used for verification of the video system should take into account the environment, lighting, characteristics of on-board video cameras and the dynamics of the underwater vehicle. In the proposed model, the virtual seabed environment is created from a schematic image based on visualization. The calculation of the lighting of the simulated scene has a ray-tracing method. The camcorder model takes into account geometric parameters such as focus, pixel sizes, etc. That model uses perspective projection rules to describe the operation of the video camera. Practical implementation of the mathematical model can simulate two on-board video cameras at the same time. The developed model takes into account the spatial movement of the underwater vehicle. The developed model takes into account the spatial movement of the underwater vehicle. This feature of the model allows you to control linear and angular velocities. Considering these characteristics makes it possible to form video frames from the position of the underwater vehicle. This article presents the mathematical model of forming video frames of the seabed by an underwater vehicle.

We consider a task of software and mathematic defining the angular position (in roll and pitch) of a spacecraft during its orbital motion under the influence of gravity torque. We suggest a new algorithm of roll and pitch angles estimation by data of only angular rate sensor. One may apply the algorithm as an alternative to measurements of the infrared vertical sensor in case of its absence or failure. The algorithm is obtained based on a solution of the two-point boundary value problem by means of analytic synthesis of modal observer for discrete identification model. A reasonable choice of parameters of the identification model and estimation algorithm is presented. Mathematic simulation and statistic tests confirm the algorithm efficiency. The limits of the algorithm applicability by the values of angles and angular rates are determined. The limits of applicability of the suggested algorithm as well as its operating speed allow applying the algorithm in real time on board an orbiting spacecraft.

The question of determining the long-term permissible currents for cable lines laid in cable channels is considered in this paper. Analysis of heat sources that must be taken into account when calculating the permissible current is given. Options for determining the permissible current, based on the formulas presented in the regulatory documents, are considered. A mathematical model of heat transfer processes in an underground cable channel, which allows taking into account the influence of neighboring operating cable lines on the temperature of the conductive core, is constructed. The temperature distribution fields in the channel are obtained. The dependences of the long-term permissible line current on the load of one and two adjacent lines are obtained. The algorithm of the operator's work with the database of load modes, in order to find new long-term permissible line currents when the load of one of the lines changes, is developed.
