Published: February 2025

In the modern criminal law system, the fight against the laundering of illegal income and criminally acquired property occupies a key position. By legalizing illegally obtained funds, criminals significantly complicate the work of law enforcement agencies in detecting and investigating primary crimes. At the same time, a number of problems, especially in the field of criminal legislation, hinder the effective opposition to this type of criminal activity. The subject of the research is the criminal law aspects of money laundering. The purpose of the work is to analyze the current state of legislation in the field of countering legalization (laundering), identify problems of law enforcement and develop proposals for improving criminal legislation. The research paper considers: statistics of those convicted under Articles 174 and 174.1 of the Criminal Code of the Russian Federation and the identification of discrepancies between the number of crimes and the number of persons brought to justice; problems in qualifying the actions of those accused of legalizing criminal funds and property; the need to prove the specific purpose of the offender; gaps in legislation regarding criminal prosecution for laundering criminally obtained funds abroad. The methodological basis of this work is the following methods: dialectics, induction, deduction, as well as statistical, formal and logical, as well as the method of regulatory analysis, which allow a deeper understanding of the problems of money laundering qualification. Results of the work – specific measures have been proposed to improve criminal legislation. Scope of application – the results can be used to improve the regulatory framework, as well as in scientific research in the field of criminal law. The scientific novelty of the study is expressed in the identification of problematic aspects and the need for amendments to Articles 174 and 174.1 of the Criminal Code of the Russian Federation, including the introduction of a minimum threshold for the amount of legalized funds and the establishment of administrative responsibility for laundering small amounts. It is also proposed to supplement the legislation with a provision on criminal liability for the legalization in Russia of proceeds from crimes committed in other countries. The conclusions that were formulated in the work emphasize that the existing legislation in the field of combating money laundering has a number of disadvantages that lead to low effectiveness in combating this type of crime.

A methodological approach to assessing the risk of fire hazard in large cities is considered. The problem is caused by the restriction of the intra-house territories of residential areas and the emergence of secondary problems in the form of the inability to reach the accident site of large-sized fire vehicles in case of an emergency. A systematic approach to improving the operational suitability of a residential area in the event of an emergency is presented. The main goal is to ensure the safety and patency of large-sized models of fire equipment. The use of a digital model is proposed to ensure the safety of the urban agglomeration. The results obtained using this methodology can be implemented into navigation applications for the fire service and ensure safety in modern agglomerations. Specific ways are presented by which the entire system can be modified to be able to intuitively change and select individual access routes in real time based on the current situation.

Introduction. Study of diverse problems coming from the theory and practice of economic competition and competitiveness of an enterprise (institution) is the subject of scientific knowledge. The topicality of the subject is assured sufficiently with existence of market economic relations. The goal of the research is a conceptual formulation and presentation of author`s understanding of the methodology of comprehensive analysis for building the competitiveness of an enterprise (institution). The objectives: 1) to describe the stages of comprehensive analysis for building the competitiveness of an enterprise (institution); 2) to define the logical and functional interrelationships between the stages of comprehensive analysis for building the competitiveness of an enterprise (institution); 3) graphically present the stages of carrying out a comprehensive analysis for building the competitiveness of an enterprise (institution). Methods and technics. The research is implemented within systems and dialectic methodology. Monographic analysis is the major research method, resulted in the synthesis of author’s presumptions and propositions. Interpretation of results and analysis. The analysis for building the competitiveness of an enterprise (institution) should include a more extensive research programme, that could be named “comprehensive analysis for building the competitiveness of an enterprise (institution)”. As indicated in this article, it integrates various techniques, joint and consistent under general logical and functional interrelationships, use of which enables (to a high degree of accuracy and relevance) a guarantee of knowledge about the peculiarities for building the competitiveness of an enterprise (institution) in diverse fields (economic activities). Conclusions. Against the background of objective multiparadigmatism in social sciences as a whole and in the economy in particular, it is obvious that the offered programme of comprehensive analysis for building the competitiveness of an enterprise (institution) should not be considered as a completely finished methodological concept. Development of economic science and changes in economic practices leave open the possibilities for transformation and enhancement of any programme for study the economic entities and processes.

Introduction. In various areas of human activities (medicine, technology, etc.), there are quasiperiodic processes. Their study and analysis require adequate statistical simulation models. The properties of theoretical models, for instance, the typical Gaussian random process, usually do not fit the processes in question. Thus, it is imperative to build models by the observed implementations of the processes. The aim of the research was to study the possibilities of application of Markov model for modeling differential rhythmogram. It seems rather promising to apply simple Markov model of a random process, which transition probability matrix contains a large number of parameters that can be estimated by the received process implementations. Conclusions. The model allows to display a variety of statistical and correlation properties. It is enabled to integrate estimates of the transition probabilities of the model by the onetype implementations of the random processes. Markov model can be employed in problems of classification of random processes by observed implementations. Analysis of the time properties (rhythmograms) of quasiperiodic processes and their modeling is conveniently carried out with the use of differences of adjoint periods (differential rhythmograms).

В КВ-диапазоне на работу различных радиотехнических систем негативное влияние оказывают сосредоточенные и флуктуационные помехи, фильтрация которых необходима при организации оптимального приёма. Повышение эффективности работы систем требует развития алгоритмов автоматического обнаружения сигнала. Обычно фильтрация помех при приёме осуществляется после демодуляции. Однако преддемодуляционная фильтрация имеет свои преимущества, особенно в случае применения сигналов с расширенным спектром. В этой связи в работе представлены новые алгоритмы фильтрации помех, способствующие увеличению энергетического выигрыша при приёме широкополосных сигналов. Представлены результаты проведённых натурных экспериментов по верификации данных алгоритмов при зондировании трассы о. Кипр г. Йошкар-Ола.
Introduction. Currently, image processing for getting additional information on the object in question is topical for research. In particular, there is a problem of extracting information on parameters of multiple ionospheric HF radio channels from ionograms, obtained by ionosphere sounding. The problem is that the images are corrupted with noise, because a sounder receiver encounters interference signals of different physical origin. It shall be noted that quite a lot of research into the ionograms processing were carried out. In our studies we proposed to apply methods of computer filtration of images. The aim of the research was the development and study of the algorithms of interferences filtration at the wideband signals reception in systems of diagnosing ionospheric HF communication links with the use of SDR technology. Findings. Paper presents the scientific justification of the algorithm of adaptive whitening of noise in HF band at the LFMCW signal reception. Software implementation of the developed complex algorithm of ionogram image processing is presented. Full-scale experiments were carried with the use of the developed facility with the LFMCW signal based on the software-defined radio technology. In further research, it is planned to perform experiments on studying the efficiency of whitening in the case of high levels of the LFMCW signal.

Рассмотрены вопросы измерения амплитудно-фазового распределения антенн методом фокусировки в ближней зоне излучения. Показаны возможные пути использования данного метода, а также пути его модификации для практических приложений. Обсуждается точность полученных результатов.
Introduction. Currently, the stage of development and testing of special-purpose antennas often poses a necessity to control their aperture distributions with the use of the general-purpose equipment. Despite the significant achievements in this area, antenna diagnosing is still topical, especially due to the use of hybrid-mirror antennas in state-of-the-art active antenna arrays (AAAs). For these purposes, a large number of different techniques have been proposed, developed, and are being used. First of all, these are direct measurements of amplitude-phase distributions (AFD) in the antenna aperture. There are a large number of methods for measuring these values and devices for their implementation. Carrying out the indicated measurements directly in the aperture or at least at a small distance from the antenna is technically impossible in some cases that are important for practice. For these cases, there were proposed methods that are based on measuring the parameters of the electromagnetic field of the antenna in the near field zone with the subsequent measuring the desired AFD by the appropriate data processing. Currently, not only are developed methods for measuring radiation patterns in the far field zone, but also the relevant software and hardware. The aim of the research is to improve the algorithm for reconstructing the AFD of the antenna with the use of the measurements in the near field zone. The modification of the restoration method consists in the fact that previously there was used a model representation of the sensor radiation pattern (a virtual array element) in the form of the function as well as there were proposed recommendations on choosing the step, electric dimensions and focal length of the virtual array to minimize the deviation of the measured AFD from real one. In fact, the sensor radiation pattern (typically, the open end of a standard waveguide is used) is somewhat different from the model. Findings. It is shown that the use of a model of radiation pattern reduces the quality of reconstruction by the focusing method. The difference between the reconstruction results using the model and the real RP decreases with the increase in the relative focal length z0/Lап and becomes negligible at z0/Lап 0.50.75. Conclusion. So, measurements of asymmetric AFD, as well as at small focal lengths, require the use of as accurate as possible sensor RPs, that are measured experimentally or calculated with the use of reliable electrodynamic modeling procedures.

Introduction. In the processing of dynamically changing data, for instance radar data, the presentation of various data arrays containing information on the routes and signs of air objects is crucial. In the practical implementation of the computational process, it seemed natural that finding the necessary information on a specific airborne object, updating and processing into data arrays was traditionally carried out by the element-by-element search method. At the same time, the representation of data arrays in the form of matrices and the use of matrix algebra provide a good opportunity to form the optimal calculations in tertiary processing. Theoretically, calculations with data arrays represented by matrices allow to eliminate element-by-element enumeration of data and yield output data immediately in the form of array. The formation of matrices and actions with them require a significant computational resources, therefore, one can assume a certain gain in computation time if there is a large amount of data in arrays, at least several thousands. The aim of the research was the development of algorithms for replacing dynamically changing data in arrays based on the mathematical apparatus of matrix algebra and the study of their application limits. A certain example of a tertiary network processing algorithm for radar information shows the sequence of the most frequently repeated operations, such as searching and replacing an array element.
