Delivery of broadband services to subscribers on the basis of optical components is based on optical access networks. The article presents the types of network topologies that are relatively easy to organize by analyzing the structure of a passive optical communication network. In particular, on the example of passive optical networks, several types of topology were analyzed and a reliable and easily organized type of topology was selected. Reliability models of passive optical communication networks have been developed, and analytical expressions of a number of reliability indicators of the network on these models have been developed. These models allow to design a passive optical network for communication subscribers located in scattered areas and to study its reliable operation. These models make it possible to design a passive optical network for communication subscribers located in scattered areas and to study its reliable operation. Based on these analytical expressions, it is possible to determine the reliability index of subscribers of a certain region. On the basis of the mentioned architecture, it is possible to achieve a high level of the reliability indicator of the optical communication zone. It provides a backup architecture using the analysis results of the previous architectures. We created each of the images below using Microsoft Visio.

Digital signal processing is one of the fastest growing technologies today. Currently, it is developing more in the direction of artificial intelligence for the analysis and synthesis of speech signals. Digital signal processing is real-time informatics designed to solve the problems of receiving, processing, reducing redundancy and transmitting information at the rate of its receipt. And processing speed plays an important role in real-time speech signal processing. Timely collection, highspeed processing, and data transmission currently require highperformance hardware and software. But high-performance problems have not been fully resolved till present. This article is devoted to the analysis and research of methods for spectral analysis of a speech signal using the Haar wavelet, as well as parallel programming and development of a parallel processing algorithms based on the OpenMP and TBB standards. For hardware implementation, two multi-core processors with different characteristics were chosen.

Photoluminescence measurements have been carried out to investigate the effects of the doping compensation on the near band edge emission lines in the nitrogen doped ZnO thin films grown on silicon substrates by using ultrasonic spray pyrolysis method. The results of the PL spectra for the N-doped layers show that the peak positions of the near band edge emission lines shift to higher energy with increasing temperature within the low-temperature region. The radiative recombinations of the carriers are related to the band-tail states, and the temperature-dependent blueshifts are analyzed by using a Gaussian distribution of the charged impurities.

Optical losses of ellipse-nested elliptical negative curvature hollow-core fibers are numerically presented for the terahertz region. Primary design parameters of all fibers were iteratively optimized and confinement and total losses as low as $2.79 times 10^{-5} mathrm{~dB} / mathrm{m}$ and $0.015 mathrm{~dB} / mathrm{m}$ were achieved at 0.55 THz, respectively. Single-mode light guidance of the proposed design was investigated and a higher-order mode extinction ratio of around 3000 was calculated.

The process of predicting changes in the levels of groundwater and pressure water and salt concentration in layers with good and poor conductivity is discussed in the article. Research and decision-making on this process using mathematical modeling is an urgent problem. A brief analysis of scientific papers devoted to mathematical and numerical modeling of the object under study is presented. To conduct a comprehensive study of the process under consideration, a model and an efficient numerical algorithm based on the finite difference method were developed. It has been studied that changes in the level of ground and pressure water, filtration permeability, water loss coefficient and filtration rate associated with the water level can have a serious impact on the environmental process. As follows from the analysis of the computational experiments, the main factors that significantly affect the filtration of ground and pressure waters and salt concentration are filtration conductivity in the layers, water loss coefficient, and filtration flow velocity in the layers. The results obtained based on these developed numerical algorithms were analyzed. Before introducing new technologies, recommendations were developed to predict changes in salt content in water using an effective numerical algorithm
本文讨论了在导电性好、导电性差的地层中预测地下水、压力水和盐浓度变化的过程。利用数学模型对这一过程进行研究和决策是一个迫切需要解决的问题。本文简要分析了对所研究对象进行数学和数值模拟的科学论文。为了对所考虑的过程进行全面研究,建立了基于有限差分法的模型和有效的数值算法。已有研究表明,与水位相关的地下水位和压力水位、过滤渗透率、失水系数和过滤速率的变化会对环境过程产生严重影响。通过计算实验分析可知,对地压水过滤和盐浓度影响较大的主要因素是层内过滤电导率、失水系数和层内过滤流速。并对所开发的数值算法的计算结果进行了分析。在引入新技术之前,建议使用有效的数值算法来预测水中盐分含量的变化

Application of artificial neural networks in the classification of classical encryption algorithms 人工神经网络在经典加密算法分类中的应用

Cryptography, which has a long historical process, has different encryption algorithms. The first step of any cryptanalysis is to try to determine what type of encryption method that ciphertext uses. This cannot be easy in any process because many types of encryption are currently available. This problem can be solved using artificial neural networks. In this study, we developed a model that discriminates the type of Affine, Playfair, and Vigenere encryption algorithms using neural networks. The research software is based on the Python programming language and its TensorFlow library, as well as Keras. This paper presents the current advances in research on the use of artificial neural networks for cypher-type detection. A built-in neural network can correctly classify encrypted texts by about 95%. The article reveals the possibilities of determining the type of encryption based on an artificial neural network. It can be seen that new methods of cryptanalysis can be developed from artificial neural networks.
密码学有一个漫长的历史过程,有不同的加密算法。任何密码分析的第一步都是尝试确定密文使用哪种类型的加密方法。这在任何过程中都不容易,因为目前有许多类型的加密可用。这个问题可以用人工神经网络来解决。在这项研究中,我们开发了一个模型,该模型使用神经网络区分Affine, Playfair和Vigenere加密算法的类型。该研究软件基于Python编程语言及其TensorFlow库,以及Keras。本文介绍了目前利用人工神经网络进行密码类型检测的研究进展。内置的神经网络对加密文本的分类准确率约为95%。本文揭示了基于人工神经网络确定加密类型的可能性。由此可见,人工神经网络可以发展出新的密码分析方法。

The first step of any cryptanalysis is to try to determine what type of encryption method that ciphertext uses. This cannot be easy in any process because many types of encryption are currently available. This problem can be solved using artificial neural networks. In this study, we developed a model that discriminates the type of Affine, Playfair, and Vigenere encryption algorithms using neural networks. The research software is based on the Python programming language and its TensorFlow library, as well as Keras. This paper presents the current advances in research on the use of artificial neural networks for cypher-type detection. A built-in neural network can correctly classify encrypted texts by about 95%.
