Purpose of this paper is to develop a license plate detection and recognition module optimized to work under constraint of edge computing. Existing methods of license plate recognition are analyzed. Dataset with images of rectangular and square license plates is collected. Detector is trained, methods of processing detected license plate frame and checking combination of symbols are implemented. Pipeline using convolutional recurrent network for character recognition adapted for license plates is developed. Influence of hyperparameters on speed and accuracy of license plate character recognition has been investigated. Experiments have demonstrated obtaining an optimal configuration for module inference with sufficiently high accuracy rates and possibility of operation under conditions of limited computational resources in real time.

In this article, we will analyze methods for modeling user ratings of a video sequence and their potential application to extended reality systems. The main approaches and algorithms used to evaluate the quality of a video sequence are considered, their advantages and disadvantages for 2D and 3D content are revealed. The aim of the work is to develop our own method for evaluating the quality of 3D models to improve relevance and efficiency, taking into account the features of 3D content, since most of the metrics were created to meet the needs of two-dimensional systems. The research results can be used in the development and optimization of augmented reality systems, as well as in other areas where it is necessary to evaluate the quality of 3D models based on user preferences.

PowerShell is a widely utilized tool by both system administrators and attackers for performing complex management tasks and launching attacks. The detection of malicious scripts poses a significant cybersecurity challenge due to the use of various obfuscations and the intricacy of analyses. This paper aims to provide a comprehensive overview of state-of-the-art techniques for detecting malicious PowerShell scripts using machine learning. It also discusses the potential integration of these techniques into SIEM (Security information and event management) systems to enhance threat detection. The final section of the paper puts forward a novel approach based on deep neural networks that utilizes a recurrent network architecture with deployed layers. Experimental results demonstrate the efficacy of the proposed model in accurately and reliably classifying obfuscated and complex scripts.

The design of on-board computer systems associates with a large number of calculations and the implementation of complex algorithms. Analytical and simulation models develop for this purpose. These models must take into account a significant number of factors, which include environmental influences, load fluctuations, and others. Queuing theory methods widely uses in modeling on-board computer systems. Queuing network models may be either open or closed. It becomes possible to take into account the network users operation technology when calculating the characteristics of this a model in the latter case. It is necessary to use special software or develop your own programs using algorithmic programming languages in any case. The processes taking place in on-board computer networks describes by the Erlang processes. Software implementation of it has been has quite complicated for a long time. In 1974 Jagerman develops a fast algorithm that implemented Erlang formula however. This paper provides examples of models and programs that allow you calculate the characteristics of on-board computer systems with a complex structure of user dialogue based on the Jagerman algorithm and Brown method for solution of nonlinear equations.

Currently, due to the rapid development of the Internet of Things, the growth in the number of devices requiring code division leads to a shortage of orthogonal code sequences to meet the needs of communication systems. This article proposes to use quantized Frank sequences for orthogonal code division of subscribers in the orthogonal code-chirp division multiplexing technology to expand the ensemble of code sequences for dividing devices. In the orthogonal code-chirp division multiplexing technology, the code sequences of subscribers divided by the ensemble are transmitted on a set of frequency subchannels with a linear-frequency carrier frequency. The comparative effect of quantized Frank sequences on the noise immunity of such a communication system is analyzed on the bit error rate dependencies.

The choice and dynamics of the change of multilevel modulation formats on transport fiber-optic communication lines over a long period of time is considered. The total discounted capital expenditures for their implementation are selected as a criterion function. It is shown that with minimal discounted capital expenditures, we obtain the maximum value of the project's economic efficiency indicator, net present value. The difference in approaches to the introduction of new modulation formats for short and long communication lines is pointed out. The results of calculations for various scenarios of changing modulation formats are presented, and recommendations are given.

The propagation of a radio signal emitted by a spacecraft through the Earth's ionosphere is considered. The influence of the ionosphere and traveling ionospheric disturbances on the propagation of a radio signal of the decimeter and meter ranges is studied. The following are calculated: deviations of rays from rectilinear propagation, changes in delay time, phase lag, and phase deviation. The total electron concentration and Faraday rotation are calculated in the presence of ionospheric inhomogeneities. The influence of the ionosphere on the absorption of a radio signal, its amplitude, and polarization is analyzed.
