Authors: Khac Tung Nguyen , Vlasov Sergey M. , Pyrkin Anton A.
Published: December 2022

The problem of adaptive tracking of the output variable of a linear stationary plant behind a multiharmonic signal under conditions of control delay and external disturbances is considered. The state vector of the object is not available for direct measurements. The reference and disturbance signal parameters (amplitudes, phases, and harmonic frequencies) are a priori unknown, and a new algorithm is proposed to improve the performance of frequency estimation of a multisinusoidal signal. Examples are given that confirm the relevance of the proposed approach.

Published: December 2022

Розглянуто семи-, восьми- і 28-членні структури трипільських орнаментів на керамічних виробах. Проаналізовано восьмичленні структури на мисках. Виділено два типи знаків, які, на думку автора, позначають богів і богинь. Висловлено думку, що пантеон трипільців складався з Богині-Матері і сімки божеств. Досліджено семичленні структури, за якими приховано сім божеств, сім сфер Космосу, сім планетних сфер і сім днів. Розглянуто 28-мичленну структуру, якою структурували Космос і міряли цикли деяких планет та жінки-богині. Висловлено думку про єдність всіх цих структур. Автор вважає, що вони є базовими  структурами світогляду трипільців, за якими приховується сімка/вісімка божеств первісного пантеону. Метод виділення і дослідження структур у первісних орнаментах дозволяє проникнути в семантику символів, з яких сформовані ці орнаменти. Дослідження структур трипільських орнаментів може бути досить плідним для проникнення у духовний світ трипільської цивілізації.

On the Issue of Forming the Perception of a Healthy Lifestyle among Youth: The Example of Vladivostok University Students
Authors: Zhuravskaya Natalya S. , Alenitskaya Marina V. , Yanovich Vasiliy A.
Published: December 2022

Introduction: Health of student youth is a strategic priority that contributes to better adaptation of students to socio-physiological processes in learning and subsequent professional labor. The lifestyle and habits affect health; thus, building and strengthening of commitment to a healthy lifestyle in young people is the only manageable resource for improving health of the society.
Objective: To analyze and assess the attitude and commitment of student youth towards values and perceptions of a healthy lifestyle.
Materials and methods: We conducted a questionnaire-based survey of university students on the perceived criteria of a responsible attitude towards their health in the 2020–2021 academic year. The questionnaire included 20 questions on the topics of health and a healthy lifestyle and was anonymously filled out by 195 first to third year students of the Vladivostok State University of Economics and Service (Group 1; 81 boys and 114 girls) and 210 students of the Pacific State Medical University (Group 2; 78 boys and 132 girls). The mean age of boys was 19 ± 0.9 to 21 ± 0.3 years and that of girls, 20 ± 0.6 to 22 ± 0.1 years. The information obtained was processed and analyzed using SPSS Statistics 17.0.
Results: We established a negative trend in the attitude of students towards their health over the study period. This applied to both self-rated health and adherence to a healthy lifestyle. Unhealthy behavioral practices, such as low physical activity, bad habits, and passive leisure, persisted.
Conclusions: The survey results served as the basis for developing proposals and recommendations on the expediency of promoting the interest of students to building healthy lifestyle skills in the changing socio-economic and epidemiological situation.
Do contato entre a Literatura, a Linguística de Corpus e o Processamento de Língua Natural
Authors: Vital Átila Augusto Soares
Published: December 2022

Da tentativa de realizar a cooperação entre a Linguística de Corpus e o Processamento de Língua Natural (PLN), foram alcançados importantes frutos, como a possibilidade de processamento de grandes dados linguísticos e o desenvolvimento de tecnologias que se utilizam de dados da língua. A relação entre essas duas áreas e os Estudos Literários, no entanto, tem sido pouco explorada, o que abre espaços para o presente trabalho, que tem por objetivo fazer uma análise exploratória da construção dos poemas atribuídos a anagramáticos de João Guimarães Rosa, em Ave, Palavra, obra de 1970. Para isso, foram utilizadas, em conjunto, abordagens da Linguística de Corpus e do PLN, associadas aos trabalhos de Rossi (2007), Brito (2012) e Vital (2021), acerca da obra rosiana. Com o processamento computacional do corpus, pudemos extrair: a) o número de palavras; b) a razão type-token; c) o número de estrofes e de versos e d) as palavras mais frequentes para cada um dos anagramáticos. Os dados foram dispostos em gráficos e nuvens de palavras (wordclouds). Desses resultados, foi observado que existem, de fato, diferenças quantitativas e qualitativas presentes no nível poético, reafirmando, por meio de observações das epígrafes de cada anagramático, a complexidade envolvida na criação da metapoeticidade de suas máscaras.

ELABORATION AND RESEARCH OF A MODEL OF OPTIMAL PRODUCTION AND DEVELOPMENT OF INDUSTRIAL SYSTEMS TAKING INTO ACCOUNT THE USE OF THE EXTERNAL RESOURCES
Authors: Hryshyn Dmytro , Borovska Taisa , Kalizhanova Aliya
Published: December 2022

The problem of optimization of investment projects related to the development of modern production systems is considered. The tasks of managing of operation and development of production systems considering external resources – the synthesis and analysis of optimal credit strategies – are posed and solved. An analysis of analogs – solutions of the variational problem of optimal development, the disadvantage of which is the difficulty of obtaining information about the state of production and the external environment, was carried out. The new solution is based on the resource approach, when external resources are taken into account in the cost of production resources. A generalized model of optimal development is used, in which the planned period of the investment project is divided into intervals. At the beginning of each interval, the optimal development strategy is adjusted taking into account the clarification of information about the future state of the active environment: actions of competitors, consumers, world markets. To determine the optimal amount and optimal distribution of credits between subsystems, the maxima of the criterion – the parameterized function of the system's efficiency – are determined at each interval. A new model has been developed based on the model of optimal development, which takes into account the use of external resources, such as loans. The method of including an external resource in the development function and the production function is considered. Examples of modeling are given.
DIGITAL APPROACH TO THERMIONIC EMISSION CURRENT TO VOLTAGE CONVERSION FOR HIGH-VOLTAGE SOURCES OF ELECTRONS
Authors: Kania Bartosz
Published: December 2022

The thermionic emission current is used in many vacuum devices such as evaporators, rare gas excimers, or electron beam objects for high-energy physics. The stability of the thermionic emission current is a very important requirement for the accuracy of those devices. Hence, there is a number of control systems that use a feedback signal directly proportional to the emission current in order to stabilize the thermionic emission current. Most of them use feedback from a high-voltage anode circuit to a low-voltage cathode circuit. However, there is a novel solution that uses linear cathode current distribution and processing of two cathode circuit voltage signals for converting the emission current to voltage. However, it is based on old-fashioned analog technology. This paper shows the thermionic emission current to voltage conversion method with the use of a digital control system. A digital realization of a multiplicative-additive algorithm is presented and proper work in closed-loop mode is confirmed.

A comparative analysis of performance of Flutter and Xamarin development frameworks
Authors: Uciński Mateusz , Dzieńkowski Mariusz
Published: December 2022

This article presents a comparative performance analysis of two cross-platform development frameworks Flutter and Xamarin. Using these technologies identical test applications running on Windows and Android were created. Each of these applications included functionalities to run test scenarios. They concerned calculating the 30th word of the Fibonacci sequence, sorting with the MergeSort algorithm lists consisting of five thousand and ten thousand elements, performing basic database operations on the database, such as record, reading, searching, modifying and deleting data. The scenarios were repeated ten thousand times, and the average execution times of the operations were analyzed. The results did not conclusively show which framework is more efficient. However, in general, it can be concluded that for applications running on Android and Windows that perform a lot of calculations or save large amounts of data or search and at the same time modify data, the Flutter framework will be a better solution.

Statics and Dynamics of Description
in S.T. Coleridge’s Poem «The Rime of the Ancient Mariner»
Authors: Zinoveva Irina
Published: December 2022

The research task is to study the nature of the correlation of the three main parts of speech in the text of the poem by S.T. Coleridge’s «The Rime of the Ancient Mariner», one of the first poetic works of English romanticism. Part-of-speech features are involved in the study, reflecting the nominality and nature of

the description: nouns, verbs and adjectives.

The study uses both directly observed frequencies and indexes reflecting them. The absolute frequency numbers of nouns, verbs, and adjectives recorded in each part have been normalized through dividing by the number of words in

each part, which made it possible to obtain comparable data for parts of the poem that differ significantly in volume.

A number of statistical procedures are used for the analysis: Busemann

coefficients, and the coefficient of variation, chi-square test. Their application made it possible to determine the relationship between statics and dynamics in the text. A power function is used to reflect the frequency distribution of nouns,

which proved to be very successful for this material. It allows us to determine the

degree of nominalization of various parts in the poem.

The results of the study indicate a fairly high stability of Coleridge’s style within the framework of the poem in terms of nominalization and dynamics of description. In addition, the article notes strong prevalence of the dynamic description over the static one.
A Letter as a Fact of Literature: Letters by L.Ya. Ginzburg and V.S. Baevsky
Authors: Dvoenko Yana , Zakroeva Galina
Published: December 2022

he archives of the literary critic V.S. Baevsky are kept in the fonds of the

Literature Museum of Smolensk State University. The materials of the scholar’s

archive have not been presented to the public yet. Meanwhile, the fonds contain

a collection of more than a thousand letters from addressees from all over the

world, including such outstanding scientists of the twentieth century as B.Ya. Bu-

khshtab, M.L. Gasparov, L.Ya. Ginzburg, Yu.M. Lotman, B.F. Egorov and others.

Correspondence was of particular importance for the philologists of that gener-

ation, as it made it possible to combine life, history and science. Comparison of scientific views, the need for an independent censor and

obtaining an objective assessment of scientific works are included in the topics

reflected in the letters from L.Ya. Ginzburg to V.S. Baevsky. Their correspondence

and memoirs testify to the coincident temporal rhythms and allow us to trace the

scientific thought of the scholars that lived almost the entire twentieth century.

This paper reconstructs the role of a letter as a fact of scientific autobiography.

It shows its transformation from the genre of «human documents» (letters and

diaries) into the genre of «intermediate literature» (memoirs). Thus, the personal

letters of L.Ya. Ginzburg acquire the status of a literary fact, since they represent

a narrative unit in V.S. Bayevsky’s life
Features of the Language Assessment Expression
in B. Akunin’s Cycle of Novels about the Nun Pelagia
Authors: Fomina Yulia
Published: December 2022

The article is devoted to the study concerning the peculiarities of the expression of linguistic evaluation in a literary text. The subject of the study comprises the evaluation tools used in B. Akunin’s cycle of novels about the nun Pelagia when the

writer creates the image of the main character. The purpose of the analysis regarding the means of expressing evaluation is to identify their role in revealing the author’s idea and in the formation of the hero’s image in the literary work, as well as to determine the individual author’s features of language evaluation.

The study of evaluation as a universal category and its reflection in the language is based on the concepts and methods that have become classical in Russian philology (the works of N.D. Arutyunova, E.M. Wolf, A.A. Ivin, etc.), as well as on the achievements of modern research.

The study has found that language evaluation tools play a significant role in revealing the image of the main character in the cycle of novels by B. Akunin. The paper notes two directions of the formation of axiological meanings in creation of the image of the nun Pelagia: an assessment of the appearance and an

assessment of the heroine’s character. The analysis has showed that the linguistic means of expressing evaluation are used in the context of the situation and the heroine’s role (Polina Andreyevna Lisitsyna, brother Pelagius, nun Pelagia). Most often, lexical means of expressing evaluation are used: adjectives, nouns,

adverbs with an evaluative meaning. The use of forms with diminutive suffixes contributes to the formation of evaluative meanings. As the author’s method of expressing evaluation, there is a violation of the norms of lexical compatibility,

which gives uniqueness to the evaluation tools used.

B. Akunin quite actively uses language assessment in describing the appearance, as well as the character and actions of the nun, while there is a discrepancy between the assessment of the external appearance of Pelagia and her internal qual-

ities, which contributes to the implementation of the author’s idea when he creates the image of the main character represented in the cycle of detective novels.

Abstract:

Most impedance-based walking controllers for powered knee-ankle prostheses use a finite state machine with dozens of user-specific parameters that require manual tuning by technical experts. These parameters are only appropriate near the task (e.g. walking speed and incline) at which they were tuned, necessitating many different parameter sets for variable-task walking. In contrast, this paper presents a data-driven, phase-based controller for variable-task walking that uses continuously-variable impedance control during stance and kinematic control during swing to enable biomimetic locomotion. After generating a data-driven model of variable joint impedance with convex optimization, we implement a novel task-invariant phase variable and real-time estimates of speed and incline to enable autonomous task adaptation. Experiments with above-knee amputee participants (N=2) show that our data-driven controller 1) features highly-linear phase estimates and accurate task estimates, 2) produces biomimetic kinematic and kinetic trends as task varies, leading to low errors relative to able-bodied references, and 3) produces biomimetic joint work and cadence trends as task varies. We show that the presented controller meets and often exceeds the performance of a benchmark finite state machine controller for our two participants, without requiring manual impedance tuning.

Tools based on deep learning models have been created in recent years to aid radiologists in the diagnosis of breast cancer from mammograms. However, the datasets used to train these models may suffer from class imbalance, i.e., there are often fewer malignant samples than benign or healthy, which can bias the model towards the healthy class. In this study, we systematically evaluate several popular techniques to deal with this class imbalance, namely, class weighting, over-sampling, and under-sampling, as well as a synthetic lesion generation approach to increase the number of malignant samples. These techniques are applied when training on three diverse Full-Field Digital Mammography datasets, and tested on in-distribution and out-of-distribution samples. The experiments show that a greater imbalance is associated with a greater bias towards the majority class, which can be counteracted by any of the standard class imbalance techniques. On the other hand, these methods provide no benefit to model performance with respect to Area Under the Curve of the Recall Operating Characteristic (AUC-ROC), and indeed under-sampling leads to a reduction of 0.066 in AUC in the case of a 19:1 benign to malignant imbalance. Our synthetic lesion methodology leads to better performance in most cases, with increases of up to 0.07 in AUC on out-of-distribution test sets over the next best experiment.
Source-free Unsupervised Adaptive Segmentation for Knee Joint MRI

Knee osteoarthritis is a prevalent disease worldwide. The automatic segmentation of knee tissues in magnetic resonance (MR) images has important clinical utility in assessing knee osteoarthritis. Deep learning- based methods show great potential in this application, but they often require a large amount of labeled training data, which is challenging and expensive to acquire. Unsupervised domain adaptation that transfers the learned knowledge from a source labeled dataset to a target unlabeled dataset can be used to address this problem. However, in medical scenarios, domain adaption techniques are often limited by access to the source data due to concerns about patient privacy. In this work, we proposed a novel and effective source-free unsupervised domain adaptation method for knee joint multi-tissue segmentation that does not require a source dataset. The proposed framework is split into two stages. In the first stage, matching batch normalization statistics guides the first segmentation network to realize model adaptation and is combined with augmented entropy minimization to obtain pseudo segmentation labels for the target MR images. The pseudo labels generated by the first segmentation network are then refined using a voting strategy to supervise the training of the models in the second stage. In the second stage, uncertainty-aware cross pseudo supervision is used to further boost the performance of the desired segmentation network, which comprises an encoder and a primary decoder. Our experiments demonstrated that the proposed method outperforms the current state-of-the-art source-free unsupervised domain adaptation techniques for segmenting knee tissues in MR images. Our study also demonstrated that the proposed approach is effective in reverse-directional adaptation.

This paper presents a chance-constrained rollover-free manipulation planning method for robotic arms under payload mass uncertainty. The corresponding motion planning problem is stated as a chance-constrained nonlinear optimal control problem (NOCP) subject to kinematics and rollover stability constraints. The latter takes the form of a chance constraint that ensures a certain probability of the robot maintaining dynamic rollover stability in the presence of payload mass uncertainty. To achieve efficient solutions to the NOCP, a novel geometric bound for the stability region is derived. The novel bound is then utilized to modify the rollover-stability constraint. To showcase its benefit, comparisons between the proposed bound of probabilistic rollover stability measure and the naive noise model are provided through statistical analysis. The formulation's practicality is demonstrated through experiments with a Kinova Jaco 2 arm mounted on a free-to-roll platform. Results demonstrate greater robustness of the robot's motion plan to mass uncertainty and computational efficiency of the trajectory generation.

Published: December 2022

 In this paper, we study the outage and ergodic rate performance of a rate-splitting multiple access (RSMA)-based cognitive radio (CR) system, where the secondary transmitter aims to communicate with two RSMA users. Imperfect successive interference cancellation (ipSIC) and channel estimation errors (CEEs) are considered in the proposed analysis. Analytical expressions for the outage probability (OP) and the ergodic rate (ER) are calculated. For a deeper understanding, the asymptotic behavior of OP and ER at high signal-to-noise ratio (SNR) regimes are carried out. Illustrative simulation results are presented and reveal that: i) The OP decreases and the ER gradually increases with the increase of SNR, and eventually approaching a constant; ii) ipSIC and CEEs have a negative impact on the considered system; iii) The outage and ergodic rate performance of RSMA-based CR network outperforms CRNOMA network due to flexible power allocation between common and private messages; iv) The OP first decreases and then increases with the power allocated to the common message, and there exists an optimal power allocation factor to ensure the reliable performance. 
Are Classifiers Trained on Synthetic Data Reliable? An XAI Study
Authors: IQBAL ASIF , Sikdar Biplab
Published: December 2022

Machine learning (ML) solutions are being applied in many areas of our daily lives, but they often require high-quality, balanced datasets in order to perform well.

However, datasets for real-world problems are often imbalanced, requiring the use of special-purpose ML algorithms or synthetic data to address the class imbalance.

Traditional techniques such as Synthetic Minority Oversampling Technique (SMOTE) and generative models such as Variational Auto Encoders (VAE) and Generative Adversarial Networks (GAN) are commonly used to generate minority class samples. 

Evaluating the quality of synthetic samples can be challenging, and researchers often rely on improved classifier performance as justification for their use.  

However, simply performing well on a test set is not sufficient to ensure the trustworthiness of a model, and further analysis of model predictions is necessary. 

To address this, we trained multiple classifiers on synthetic data generated by various methods and analyzed their predictions using SHAP, an explainable AI technique. 

Our in-depth analysis showed that these classifiers used different features for making predictions and placed different levels of importance on commonly used features. Therefore, we conclude that classification models trained on synthetic data must be carefully analyzed by human experts before being deployed in the real world.

Published: December 2022

Full leverage of the huge volume of data generated on a large number of user devices for providing intelligent services in the 6G network calls for Ubiquitous Intelligence (UI). A key to developing UI lies in the involvement of the large number of network devices, which contribute their data to collaborative Machine Learning (ML) and provide their computational resources to support the learning process. Federated Learning (FL) is a new ML method that enables data owners to collaborate in model training without exposing private data, which allows user devices to contribute their data to developing UI. Edge computing deploys cloud-like capabilities at the network edge, which enables network devices to offer their computational resources for supporting FL. Therefore, a combination of FL and edge computing may greatly facilitate the development of ubiquitous intelligence. 

In this article, we present a comprehensive survey of the recent developments in technologies for combining FL and edge computing with a holistic vision across the fields of FL and edge computing. We conduct our survey from both the perspective of an FL framework deployed in an edge computing environment (FL in Edge) and the perspective of an edge computing system providing a platform for supporting FL (Edge for FL). From the FL in Edge perspective, we first identify the main challenges to FL in edge computing and then survey the representative technical strategies for addressing the challenges. From the Edge for FL perspective, we first analyze the key requirements for edge computing to support FL and then review the recent advances in edge computing technologies that may be exploited to meet the requirements. Then we discuss open problems and identify some possible directions for future research on combining FL and edge computing, with the hope of arousing the research community’s interest in this emerging and exciting interdisciplinary field.

Based on the results of observations, it was found that the quality of management of the company was found to be a factor of disability originating from delays in arriving raw materials, operator errors and untimely mixing. It is known from calculations using the FuzzyFMEA method with FRPN values. As for the existing failures, it occurred in Rank 1 of 72900 with failures occurring due to operator error, Rank 2 of 57600 with failures occurring because the mixing process was not carried out on time, and Rank 3 of 51200 with failures occurring due to delays in the arrival of raw materials. Calculations in the second study were carried out using the Taguchi method from values ​​calculated with the help of Qualitek-4 and FMEA software. The research objective was carried out to optimize product quality, and also to provide input for improvement in the cast concrete mix process. Based on the results of the FRPN the following are (Rank 1), namely the results obtained on the identification of the risk of failure carried out by operator error, namely 72900. And based on calculations using the Taguchi method of cast concrete mix, namely with a guide weight of sand 980 (kg), weight of cement 30 (kg), stirring time 450 (seconds), volume in water 40 (liters) and gravel weight 5 (kg).
