Published: November 2023

One of the priority tasks of the energy industry is to ensure the reliable and safe operation of steam turbine units of thermal power plants and nuclear power plants. Given the difficult situation in the country, it is impossible to replace outdated equipment that has exhausted its design resource with new ones. As is known, the safety factor of the material taken into account during the design of steam turbine equipment was very approximate. At that time, there were no data on the operation of power equipment, which would have already worked for 200-220 thousand hours. in difficult operating conditions. The situation has changed now. There are power installations that have exhausted or are close to exhausting their design resource. By conducting experimental studies with metal samples of this equipment, it is possible to significantly clarify the physical and mechanical properties of steels and their damage due to operation. Therefore, the problem of extending the resource is becoming increasingly important. Computer modeling has greatly simplified the task of calculating the resource of the equipment. However, such a complex object as a steam turbine requires significant computing resources, and the calculation of equations in all finite element nodes is quite time-consuming. It is necessary to look for ways to rationalize calculation mathematical models. At the same time, the accuracy of the calculation should remain at a satisfactory level. In this work, were created simplified geometric models of the rotor of the LPC turbine unit  К-1000-60/3000. The option is considered of replacing the working blades with equivalent distributed masses and toroidal rings. Verification of the obtained models based on critical rotation frequencies confirmed the possibility of replacing the working blades with distributed masses. On the other hand, the presence of toroidal rings of large radii leads to a significant reduction of critical frequencies in comparison with normalized values.
DETERMINATION OF THE VISCOSITY OF A MULTIPHASE MEDIUM USING THE THEORY OF SIMILARITY AND THE THEORY OF THE REGULAR THERMAL REGIME
Authors: Vlasenko Olga
Published: November 2023

The properties of each liquid can be characterized by a whole complex of various physical quantities: values of density, viscosity, electrical conductivity, heat capacity, surface tension, etc. At the current stage of technological development, the measurement of liquid viscosity is an urgent task in various areas of human life: automotive, oil and gas, aviation, food, medical and a number of other industries. Viscosity (internal friction) is the property of fluid bodies (liquids and gases) to resist the movement of one of their parts relative to another. Viscosity is a non-constant value and changes depending on the temperature of the liquid medium, the presence of impurities in its composition, and the value of the resource. It can be kinematic, dynamic, conditional and specific. However, indicators of kinematic or dynamic viscosity are most often used. The experimental results of viscosity determination were obtained on the stand, which is a component of the experimental and calculation method. The main elements of the experimental setup are two working cavities - external and internal. Criterion equations in the first and second approximation, consisting of similarity criteria, namely the Reynolds criterion and the Prandtl criterion, were developed to describe the heat transfer to three-phase media. Viscosity was determined in the first approximation using the criterion equation for "model liquids", and in the second approximation using the criterion equation obtained jointly for "model liquids" and the substrate. The difference between the viscosity found in the two approximations is up to ±30...40%. Key words: regular thermal mode, biogas, substrate, biogas installation, thermal stabilization, thermophysical properties, experimental and calculation method, mathematical model.
Боротьба проти безробіття: історичний досвід волині періоду НЕП

Published: November 2023

У статті комплексно проаналізовано підходи радянських органів влади на Волині для боротьби з безробіттям під час періоду Нової економічної політики (НЕП). Виявлено, що встановлення надійного контролю над показниками ринку праці було складним завданням; адміністративно-командні процедури переважали в зусиллях із подолання безробіття, а бюрократична спрямованість на полегшення безперешкодної роботи бірж праці була недостатньою. Проте ініціатива режиму щодо надання фінансової допомоги безробітним щомісяця визнавалася позитивним кроком, що дало змогу спрямувати значні кошти на вирішення дотичних проблем і використання громадських робіт для зменшення кількості безробітних. Попри все, дискусія щодо безробіття серед жінок та підлітків на Волині залишається малодослідженою і потребує глибшого вивчення.

Ключові слова: безробіття, Волинь, біржа праці, нова економічна політика, радянська влада.

Research on hybrid transformer-based autoencoders for user biometric verification
Authors: Havrylovych Mariia , Danylov Valeriy
Published: November 2023

Our current study extends previous work on motion-based biometric verification using sensory data by exploring new architectures and more complex input from various sensors. Biometric verification offers advantages like uniqueness and protection against fraud. The state-of-the-art transformer architecture in AI is known for its attention block and applications in various fields, including NLP and CV. We investigated its potential value for applications involving sensory data. The research proposes a hybrid architecture, integrating transformer attention blocks with different autoencoders, to evaluate its efficacy for biometric verification and user authentication. Various configurations were compared, including LSTM autoencoder, transformer autoencoder, LSTM VAE, and transformer VAE. Results showed that combining transformer blocks with an undercomplete deterministic autoencoder yields the best performance, but model performance is significantly influenced by data preprocessing and configuration parameters. The application of transformers for biometric verification and sensory data appears promising, performing on par with or surpassing LSTM-based models but with lower inference and training time.
Detection of Unauthorized Actions in Networks Using Wavelet Analysis
Authors: Hrynchenko Pavlo
Published: November 2023

Signal processing techniques are used to analyze and detect network anomalies because of their ability to detect new and unknown intrusions. The paper proposes a method of modeling network signals for the detection of network anomalies, which combines wavelet approximation and the theory of system identification. To characterize the behavior of network traffic, fifteen functions are provided, which are used as input signals within the system. At the same time, it is assumed that security violations within the network can be detected by checking abnormal patterns of system functioning according to audit data.

Despite the fact that machine learning methods have achieved significant results in detecting network anomalies, they still face the difficulty of using the implemented algorithms, in the presence of differences in the behavior of the training data and test data, which in turn leads to inefficient performance of the algorithms. This effect is exacerbated by the limitation of algorithms to detect previously unknown types of attacks due to the large number of false positives.

The paper develops a new method of modeling network signals for detecting anomalies in networks using wavelet analysis. In particular, the general architecture of the approach consists of three components: feature analysis, modeling of normal network traffic based on wavelet approximation and prediction using ARX model, intrusion or non-intrusion decision making

The result is evaluated using the DARPA intrusion detection dataset, which performs a comprehensive analysis of the intrusions in the dataset. Evaluation results show that this approach provides a high level of detection of both instances and types of attacks.
Mathematical Model of the Process of Raising Integers to an Arbitrary Power of a Natural Number in the System of Residual Classes
Authors: Yanko Alina , Kovalchuk Dmytro
Published: November 2023

It is known that the use of a non-positional number system in residual classes (SRC) in computer systems (CS) can significantly increase the speed of the implementation of integer arithmetic operations. The use of such properties of a non-positional number system in the SRC as independence, equality and low-bitness (low-digit capacity) of the residues that define the non-positional code data structure of the SRC provides high user performance for the implementation in the CS of computational algorithms consisting of a set of arithmetic (modular) operations. The greatest efficiency from the use of the SRC is achieved when the implemented algorithms consist of a set of arithmetic operations such as addition, multiplication and subtraction.
There is a large class of algorithms and tasks (tasks of implementing cryptoalgorithms, optimization tasks, computational tasks of large dimension, etc.), where, in addition to performing integer arithmetic operations of addition, subtraction, multiplication, raising integers modulo and others in a positive numerical range, there is a need to implement the listed above arithmetic and other operations, in the negative numerical range. The need to perform these operations in a negative numerical range significantly reduces the overall efficiency of using the SRC as a number system of the CS. In this aspect, the lack of a mathematical model for the process of raising integers in the SRC in the negative numerical region makes it difficult to develop methods and procedures for raising integers to an arbitrary power of a natural number in the SRC, both in positive and negative numerical ranges.
The purpose of the article is the synthesis of a mathematical model of the process of raising integers to an arbitrary power of a natural number in the SRC, both in positive and negative numerical ranges.

Non-commutative cryptography studies cryptographic primitives and systems which are based on algebraic structures like groups, semigroups and noncommutative rings. We continue to investigate inverse protocols of Non-commutative cryptography defined in terms of subsemigroups of Affine Cremona Semigroups over finite fields or arithmetic rings Zm and homomorphic images of these semigroups as possible instruments of Post Quantum Cryptography. This approach allows to construct cryptosystem which are not public keys, when protocol finish correspondents have mutually inverse transformations on affine space Kn or variety (K*)n where K is the field or arithmetic ring.

The security of such inverse protocol rests on the complexity of word problem to decompose element of Affine Cremona Semigroup given in its standard form into composition of given generators. We discuss the idea of usage combinations of two cryptosystems with cipherspaces(K*)n and Kn to form a new cryptosystem with the plainspace(K*)n, ciphertextKn and nonbijective highly nonlinear encryption map.

The physical and mechanical properties of rocks will change significantly after being subjected to high temperatures, which poses safety hazards to underground projects such as coal underground gasification. In order to investigate the effect of temperature on the macroscopic and microscopic properties of rocks, this paper has taken sandstone as the research object and conducted uniaxial compression tests on sandstone specimens at different temperatures (20-1000 ℃) and different heating rates (5-30 ℃/min) at 1200 ℃. At the same time, the acoustic emission (AE) test system was used to observe the acoustic emission characteristics of the rock damage process, and the microstructural changes after high temperature were analyzed with the help of a scanning electron microscope (SEM). The test results show that the effect of temperature on sandstone is mainly divided into three stages: Ⅰ (20-500 ℃) stage is the strengthening zone, the evaporation of water and the contraction of primary fissures, sandstone densification is enhanced. Specifically, the compressive strength and elastic modulus increase, the macroscopic damage mode is dominated by shear damage, and the fracture micro-morphology is mainly brittle fracture. Stage II (500-600°C) is the transition zone, 500°C is the threshold temperature for compressive strength and modulus of elasticity, and the damage mode changes from shear to cleavage damage, and the sandstone undergoes brittle-ductile transition in this temperature interval. Stage III is the physicochemical deterioration stage. The changes in physical and chemical properties make the sandstone compressive strength and modulus of elasticity continue to decline, the macroscopic damage mode is mainly dominated by cleavage damage, and the fracture microscopic morphology is more toughness fracture. The effect of different heating rates on the mechanical properties of sandstone was further studied, and it was found that the mechanical properties of the rock were more deteriorated under higher heating rates.

Product introductions play a pivotal role in the success and competitiveness of manufacturing, particularly in the context of new product development. Low-volume manufacturing companies exhibit distinct characteristics that significantly influence the product introduction process. Notably, the quality of information exchange between product design and production interfaces becomes paramount in this high-mix and low-volume industry. Consequently, there exists a pressing need to explore various methods for adapting and customizing management mechanisms and strategies to align with the unique requirements and characteristics of low-volume manufacturing and its associated product introduction processes. While the need for this knowledge is critical in the context of low-volume manufacturing, a majority of existing studies predominantly focus on the management aspects within high-volume manufacturing. Therefore, the primary aim of this study is to investigate the customization of product introduction management strategies to enhance the quality of information content within the realm of low-volume manufacturing. Drawing upon a longitudinal analysis of new product introductions within a low-volume manufacturing company, this study narratively elucidates how the examined company implemented product introduction management strategies to facilitate the enhancement of information content quality during the product introduction phase. The study presents its findings on management strategies across three key stages: pre-implementation, post-implementation, and subsequent modification and refinement of strategies following the initial round of implementation. By shedding light on these strategies, this study offers a comprehensive understanding of management approaches in the context of low-volume product introduction. As a result, it makes a valuable contribution to the discourse on information management and interface management in the high-mix, low-volume manufacturing literature.

In Bangladesh, family businesses play a significant role in the country's business landscape because so few private companies are set up as large-scale, non-family ownership firms. Thus, it is vital to comprehend family businesses in order to comprehend Bangladeshi company dynamics. In this paper, authors attempted to survey the existing research in the area of family business in Bangladesh. It was found that the area as a research is totally an open field and a lot of new research can be done in the said area. Although a good number of studies can be classified as focused on the SME (small and medium enterprise) domain, a major shortcoming of those SME studies is that the SMEs themselves vary greatly in terms of size, scope, and technology. Whereas most of the family businesses can be predominantly put in the SME category, the particular issue of family business and family dynamics is not very common in those studies. This paper suggests that a good amount of research or studies can be done focusing on family business constitution, family members' participation norm, recruitment and promotion norm, family business succession rules and succession planning, training for family business leadership and management, training for board and directorial supervision, and so on.

As ethically motivated vegans (EMV) frequently feel responsible for suffering caused by the consumption of animal products, feelings of guilt are therefore an important issue for many of them. To date, studies on the experience and handling of guilt in vegans have rarely been identified. Therefore, we investigated this topic using a qualitative design. N=64 interviews with N=57 EMV were analyzed using content analysis. Key results are that they perceive guilt as a psychological and sometimes even as a physical influencing factor. They describe how feelings of guilt arise in combination with anger, revulsion and pity thereby affecting their thinking and behavior. Some experience even corporal strain, a physical heaviness. Others helped the transition to a vegan diet to get rid of guilt and to feel emotional and partially also physical relieve. In contrast, others were faced with new problems: no dissociation from other people’s guilt, heightened awareness of one’s own perception, more compassion, and a stronger sense of responsibility. Some even registered an increased tendency to depression and self-destructive thoughts. Beyond its limitations, our study is one of the first illustrating the possible impact of feelings of guilt on mental and physical well-being EMV may sense and suffer from.

Protein–nanoparticle hybridization can ideally lead to novel biological entities characterized by emerging properties, which can sensibly differ from those of the parent components. Herein, the effect of ionic strength on the biological functions of recombinant, His-tagged spermine oxidase (i.e., SMOX) was studied for the first time. Moreover, SMOX was integrated to colloidal surface active maghemite nanoparticles (SAMNs) by direct self-assembly, leading to a biologically active nano-enzyme (i.e., SAMN@SMOX). The hybrid was subjected to an in-depth chemical-physical characterization highlighting that protein structure was perfectly preserved. The catalytic activity of the nanostructured hybrid (SAMN@SMOX) was assessed by extracting kinetics parameters using spermine as substrate and compared to the soluble enzyme as a function of ionic strength. Results revealed that the catalytic function was dominated by electrostatic interactions and that they were drastically modified upon hybridization with colloidal ɣ-Fe2O3. Noteworthy, the affinity of SMOX toward spermine was significantly higher for the nanohybrid at low salinity. The present study supports the vision of using protein–nanoparticle conjugation as a mean for modulating biological functions.
