Lexical Expressions with Temporal Semantics: the Corpus Study
Authors: Timoshenko Svetlana P.
Published: December 2022

The field of study that can be named “temporal semantics” is marked by the domination of grammatical studies. The researchers’ interest is focused on the tense and the aspect, lexical expressions with temporal meaning stay in the background. Obviously, it is grammatical means that for the most part express temporal meanings: they are present in most languages and in every sentence in these languages. However, lexical means can convey the same information. We argue that the cataloging of lexical means and comparing the systems of these means in different languages allow us to outline the boundaries of human perception of time and to better understand what is universal and what is specific in it. Our goal is to conduct a corpus study of temporal lexical expressions in the Russian language. To do this, we developed an annotation scheme and performed a pilot markup on some fragments of the SynTagRus. The paper describes our annotation scheme and provides linguistic grounds for the decisions made during its development. We also compare our annotation scheme with the TimeML scheme, the most used annotation scheme for temporal information in the world. We show that despite the elaborated structure and a large set of elements, TimeML fails to grasp some important fragments of the expressions’ semantics. The proposed annotation scheme is more expressive and flexible and suits for the annotation of the complex examples: sekretarša na minutu vyšla (‘the secretary left for a minute’), delatʹ čto-libo tretij čas podrjad (‘do something more than two hours in succession’ – literally ‘for the third hour in a row’).
METHOD SUPER LEARNING FOR DETERMINATION OF MOLECULAR RELATIONSHIP
Authors:   Lviv Polytechnic National University, GURBYCH A.
Published: December 2022

This paper uses the Super Learning principle to predict the molecular affinity between the receptor (large biomolecule) and ligands (small organic molecules). Meta-models study the optimal combination of individual basic models in two consecutive ensembles – classification and regression. Each costume contains six models of machine learning, which are combined by stacking. Base models include the reference vector method, random forest, gradient boosting, neural graph networks, direct propagation, and transformers. The first ensemble predicts binding probability and classifies all candidate molecules to the selected receptor into active and inactive. Ligands recognized as involved by the first ensemble are fed to the second ensemble, which assumes the degree of their affinity for the receptor in the form of an inhibition factor (Ki). A feature of the method is the rejection of the use of atomic coordinates of individual molecules and their complexes – thus eliminating experimental errors in sample preparation and measurement of nuclear coordinates and the method to determine the affinity of biomolecules with unknown spatial configurations. It is shown that meta-learning increases the response (Recall) of the classification ensemble by 34.9% and the coefficient of determination (R2) of the regression ensemble by 21% compared to the average values. This paper shows that an ensemble with meta-stacking is an asymptotically optimal system for learning. The feature of Super Learning is to use k-fold cross-validation to form first-level predictions that teach second-level models — or meta-models — that combine first-level models optimally. The ability to predict the molecular affinity of six machine learning models is studied, and the efficiency improvement is due to the combination of models in the ensemble by the stacking method. Models that are combined into two consecutive ensembles are shown.

Published: December 2022

An urgent problem today is the need for uninterrupted and reliable energy supply of buildings and structures using alternative energy. Theoretical research was conducted in order to create a new technology of electricity generation by combining the capabilities of renewable energy sources, namely solar and hydropower. To confirm the possibility of creating a new technology of electricity generation, scientific studies of the properties of heat pipes were conducted. The possibilities of generating electricity from the energy of heated steam, which arises in the process of evaporation and movement of the coolant inside the heat pipe, are estimated. The source of energy for the evaporation process is hot water from the solar collector, which is forcibly supplied to the evaporation zone by a pump. The source of electricity for the operation of the pump and auxiliary equipment and means for cooling the evaporation zone of the heat pipe are solar panels, placed in such a way as to create a constant shadow on the surface of the heat pipe. The use of hot water from the solar collector as a heat source for the operation of such a heat pipe has made it possible to create a new technology for generating electricity with high productivity. Based on the theoretical research, the structure of the combined system of electricity generation is proposed, in which the impeller of the turbine is placed inside the heat pipe, and its heating is carried out by solar collectors, which increased the efficiency of renewable energy sources. The functional scheme of the combined system of generation of the electric power is developed and the principle of its work is resulted. The main theoretical dependences are selected and the parameters of the elements of such a combined generation system are calculated.
INFLUENCE OF HYDROGEN SATURATION ON CHARACTERISTICS OF ZIRCONIUM
Authors:   Karpenko Physico-Mechanical Institute of the NAS of Ukraine, TRUSH VASYL
Published: December 2022

The article presents a literature review on the effect of hydrogen saturation on the properties of zirconium alloys. Zirconium alloys are an indispensable structural material for the core of nuclear reactors. During operational loads, the interaction of zirconium materials with interstitial elements (oxygen, nitrogen, hydrogen) necessarily occurs. Zirconium shows the greatest affinity for hydrogen. One of the vulnerable zirconium elements is fuel rod tubes. The safe operation of a nuclear reactor depends on their integrity. In addition, it is fuel tubes that are most exposed to hydrogen. Therefore, the systematization of knowledge about the effect of hydrogen on the properties of zirconium tubes will make it possible to better predict their operational behavior. According to scientific literature data, depending on the volume of absorbed hydrogen, either a solid solution or zirconium hydrides can form. The dependence of the absorbed hydrogen zirconium on the dilution of the hydrogen medium and temperature is shown. The chemical composition of the zirconium alloy also affects the rate and amount of absorbed hydrogen. The effect of hydrogen on the mechanical properties of zirconium alloys is presented. The differences on the fracture surface after tensile tests at room temperature are shown depending on the amount of absorbed hydrogen. Data are presented that indicate that hydrogen atoms are located in octahedral or tetrahedral interstitial voids of a hexagonal close-packed zirconium lattice. It is shown that the thermal solubility of hydrogen in α-zirconium is extremely low, its value is ~6 at. % at the eutectoid transformation temperature, and at room temperature the solubility of α-Zr hydrogen does not exceed 1·10-5 wt. %. In high-temperature β-Zr, hydrogen dissolves up to ~50 at. %. It has been established that deterioration of the properties of zirconium elements of nuclear reactors during operation due to exposure to hydrogen is likely due to a number of factors: hydrogen embrittlement, the formation of large massive accumulations of hydrides and delayed hydride cracking. It is shown that the direction of arrangement of hydrides depends on the texture of the matrix and on the stresses present in the material that act during the formation of hydrides. It has been established that hydrogen can penetrate into a metal through an oxide film, diffusing, for example, along extended defects such as dislocations and grain boundaries. It is noted that the solubility of hydrogen in zirconium depends on other penetration elements already present in the metal, for example, the solubility of hydrogen in α-zirconium depends on the soluble oxygen in the metal matrix, which is confirmed by the reduced «Zr–O–H» ternary system.

Published: December 2022

The availability of reliable and systematic information on water consumption modes is the basis for optimizing the operation modes of water supply facilities. The necessity of water consumption monitoring is substantiated in order to detect changes in the operation conditions of water supply system facilities due to the influence of seasonal and social factors. The daily water consumption graph was used as an indicator of the operation mode of water supply facilities. The procedure of analysis of actual water consumption graphs is the methodological basis of the proposed information technology. It involves the search for hidden regularities in the formation of water consumption and is based on the description of irregularities and the form of daily water consumption graphs. The design of the information technology prototype is performed using a unified modeling language. The functionality and behavior of information monitoring technology is described using a use case diagram. A structured database is the information basis of information technology. It contains a structured set of initial data on daily water consumption graphs, the results of the description of their irregularities and shapes, the results of the classification of daily water consumption graphs and a formalized description of the analysis results. A relational data model was used to construct the database. The developed database contains twelve tables. Relationship between tables is defined as «one to many». Implementation of monitoring on a regular basis will ensure the accumulation of new data. The integration of the developed prototype database and information technology into the information system for monitoring the functioning of the water supply system will help to identify new knowledge about the peculiarities of the formation of the water consumption mode. This will identify changes in the actual operation conditions of water supply facilities.
CLUSTERIZATION METHOD BASED ON BREADTH FIRST SEARCH OR BFS FOR A GRAPH
Authors: PETROV DMYTRO , BOICHUK ANDRYY ,   Lviv Polytechnic National University
Published: December 2022

Clusterization is one of the types of algorithms of unsupervised learning. The idea behind it is that an algorithm learns patterns from untagged data. Such type of algorithm helps to find unseen dependencies in the untagged data itself. This paper presented algorithms based on Breadth-First Search or BFS for a Graph. The method was built based on the basic theory of clusterization. To the theory of clusterization, the calculated distance between the two farthest points in the cluster should be less than the distance between the closest two points from different clusters. By this rule, we defined that two parameters of the method should be the maximum distance between points by which these can be connected and assumed to be in one cluster. The second had to be the maximum distance in the cluster, aka the cluster’s diameter. A cluster’s diameter is the farthest distance between two points within a cluster. With these hyperparameters and the defined distance method, we can assume that every point is a vertex of a graph, two points within the threshold of the distance between pairs of ones are neighbours, and count the connection between counts as an edge of a graph. The group of connected vertexes or a particular vertex is a graph. The diameter hyperparameter ought to keep the data homogeneity in a cluster. We can define every graph as a cluster with defined rules based on previous assumptions. Later in this paper will be visualized the clusterization of three-dimensional data points. We took one of the most popular clusterization dataset – the iris dataset for visualizing purposes. The paper contains several examples of clusterization of the dataset with different hyperparameters. We took KMeans [3] as an example of the clusterization method. The method based on BFS is a flexible clusterization method that relies on meta-information about distancing between data points.

Published: December 2022

The disadvantages of using machine mechanisms in the kinematic circuits of which contain a passive connection are described. A three-dimensional statically defined mechanism of the “Turbula” type machine without the presence of a passive connection in its kinematic circuit is proposed. This design of the machine is realized due to the introduction into the kinematic circuit of an additional moving link – the second working capacity. Operation of this design of the car allows to increase productivity of processing of details considerably due to the fact that there is a possibility on one car to carry out two different technological operations at the same time or to process two parties of various details at the same time. The principle of operation of the mechanism and the machine is described. Analytical researches of the basic geometrical and constructive parameters of the galvanizing machine with two working capacities which, as a whole, provide its rational functioning are executed. The relationship between the geometric parameters of the moving parts of the machine and the change in the amplitude of their movements. In particular, mathematical dependences are obtained, which make it possible to calculate the amplitude of the angle change between the axes of two tanks, as well as the amplitude of the distance change between mutually perpendicular geometric axes of the forks to the working tanks. The operation of this machine design will significantly increase the productivity of machining parts due to the fact that it is possible to perform two different technological operations on one machine or simultaneously process two batches of different parts. The obtained results of analytical researches can be used in the corresponding design bureaus of the machine-building enterprises at a stage of designing of the galting equipment with difficult spatial movement of working capacities.

Peergroup und Schule in einer Kultur der Digitalität – Digitale (Bild-) Praxis als Grenzbearbeitung zwischen zwei Lebenswelten?
Authors: Kramer Michaela , Müller Jane
Published: December 2022

Peergroup und Schule sind zwei bedeutsame Lebenswelten Jugendlicher, deren Verhältnis zueinander im Zuge fortscheitender Mediatisierung dynamischen Wandlungsprozessen unterliegt. Die sich dabei vollziehenden Entgrenzungsprozesse theoretisch zu fassen und empirisch zu erforschen, stellt eine Herausforderung für die erziehungswissenschaftliche Jugendforschung dar, der mit einer stärkeren gegenseitigen Bezugnahme von medien-, schul- und peerbezogenen Forschungssträngen begegnet werden kann. In dieser Stoßrichtung verfolgt der Beitrag das Ziel, den sich wandelnden Verhältnissen der mediatisierten Lebenswelten nachzugehen. Hierzu wird einerseits Stalders (2021) „Kultur der Digitalität“ herangezogen, um die bereits erforschten Phänomene der Entgrenzung gesellschaftsanalytisch einzuordnen. Andererseits wird mit einem Fokus auf digitale Bildpraxis im Schnittfeld von Peerkultur und Schule diskutiert, wie die Grenzen als relationale Konstrukte von den Akteur*innen selbst bearbeitet werden.

Investigation of the main properties of reverse osmosis membranes and their influence on changes in the physico-chemical composition of aqueous solutions
Authors: Kravchenko Мarina V. , Vasylenko Lesya O.
Published: December 2022

The article discusses the relevance and features of the use of reverse osmosis when adjusting the physico-chemical composition of aqueous solutions and especially the composition of drinking water. The main element of any reverse osmosis plant is a semi-permeable membrane, which is a polymer composite material of uneven density. It has been shown that reverse osmosis membranes must meet certain requirements, the main of which are selectivity to the components that are removed at this functional stage, compliance with a high level of permeability, i.e. stable physical and chemical properties during their operation. The main physicochemical properties of membranes (selectivity, specific productivity, concentration reduction factor, separation factor) and methods for their calculation are described. The effect of temperature on the change in the selectivity and specific productivity of a semipermeable membrane for MgCl2 and CaCl2 salts has been experimentally studied. It has been proven that an increase in the temperature of the solution leads to an increase in the selectivity of the membrane and a linear decrease in the specific productivity. Experimental studies were carried out on model solutions to study the effect of pressure on the change in membrane selectivity. It is shown that the shrinkage of the membrane structure is especially noticeable in the first hours of its operation, which leads to a decrease in the selectivity of the membrane. A practically steady state in terms of selectivity usually occurs in 4–5 hours. It was studied that with an increase in the concentration of salts in the initial solution, a decrease in the specific productivity of the membrane and an increase in selectivity occur. It is shown that the selectivity of the studied membrane in the presented range of concentrations is higher for electrolytes of the 2:2 type than for electrolytes of the 2-1 type. The parametric dependences of the change in selectivity and the concentration reduction factor of the Filmtec TW30-1812-50 membrane over time for the components of a “model multicomponent solution” at a pressure of P = 18 atm are given.
What could we have learnt from the previous flood data to predict losses caused by the 1980, 1986, and 1998 catastrophic floods in Ukrainian Transcarpathian?
Authors: Stefanyshyn Dmytro V.
Published: December 2022

This paper explores some aspects relating to retrospective predicting the confirmed monetary losses caused by the disastrous floods of 1980, 1986, and 1998 in the Tisza River basin within the Transcarpathian region of Ukraine. The research was based on two time series – the losses because of past floods and the maxima water discharges gauged at the hydrological station near the village of Vylok, Vynohradiv district. The main aim of the research was to make out whether it had been the possibility to predict the losses due to those floods in advance.In solving the task, there was revealed and modelled the dependence of the risk of losses due to the floods in Transcarpathia on the maximum water discharges of the Tisza River gauged at the “Vylok” hydrological station. Predicting was based on the hypothesis of the stationary random process for maximum water discharges, which allowed using an empirical distribution function of a random variable regarding flood water discharges assessing the risk of flood losses.Retrospective predicting of the losses caused by the floods of 1980, 1986, and 1998 was carried out by means of a combined situational-inductive predictive modelling method (CSIPMM), being an original author’s development. The method relates to predicting the behaviour of complex dynamic systems based on monitoring findings presented as time series data reflecting evolutions of a resulting (dependent) variable and an explaining (independent) variable (predictor). The method uses extrapolation-regression type models. According to this method, the prediction task is performed in two stages. The first stage realises the retrospective situational modelling task aiming to obtain a set of simple regressions (situational models) built on data of sample time series. The situational models are accepted to be adequate or relevant ones only within certain periods of time determined as situations. In the second stage, based on the generalization (on an ensemble) of the obtained retrospective situational models, inductive “levels” models are built, which reflect the behaviour of a controlled parameter of the system or process (a resulting variable) at several fixed values of a predictor in time. The inductive models are used in extrapolative predicting situational models belonging to future periods (situations).In total, three predictions were made: (1) taking into account the annual maximum flood discharges from 1954 to 1979 (before the flood of 1980); (2) the same from 1954 to 1985 (before the flood of 1986); (3) the same from 1954 to 1997 (before the flood of 1998). The study found that there had been a possibility to predict the confirmed monetary losses inflicted by the flood of 1986 and 1998 (relative predicting errors of 7.2-8.7% and 6.0-12.8% depending on the prediction options).

Published: December 2022

The prospects of increasing the level of environmental safety of industrial enterprises as a result of the implementation of the latest sorption technologies for wastewater treatment are considered. An analysis of the effectiveness of the existing methods of sorption water purification, which contain compounds of heavy metals, was carried out. Highly effective magnetic sorbents were obtained by electroerosion dispersion, which contains polyvalent iron oxides.

The effect of the method of introducing the sorbent into wastewater on the degree of its purification was investigated. The most effective results in water purification were achieved with the use of freshly obtained powder of electroerosion dispersion of iron in water in the form of a suspension, which allows to achieve a high degree of water purification from zinc ions - more than 99%. Such water meets the standards for washing parts in galvanic production with regard to the content of nickel ions. The expediency of recycling spent nano-sorbents in the composition of powder paint and varnish materials is shown. When a coating chemically stable in water treatment waste, which has ferromagnetic properties, is included in the composition, in quantity15% by weight high corrosion resistance of the coating is ensured and shielding of electromagnetic radiation increases approximately 3 times compared to the standard sample. The use of research results at enterprises will prevent environmental pollution with toxic substances, change outdated production technologies, ensure efficient and rational use of water, raw materials and energy in the industrial production system.

Published: December 2022

O estudo tem como objetivo analisar as alterações ocorridas no instituto da desconsideração da personalidade jurídica após a lei nº13.874/19. O trabalho se faz importante para verificar o que de fato representou uma mudança significativa no tema e o que foram apenas alterações sem grande inovação para o ordenamento jurídico brasileiro. Com esteio no método hipotético-dedutivo, demonstra-se que a alteração legislativa positivou o que já era entendimento jurisprudencial, bem como reforçou conceitos jurídicos já consagrados pela doutrina, mas também, aprimorou parâmetros para a aplicação da teoria, possibilitando a sua utilização de forma técnica e delimitando de maneira mais rígida a atuação dos juízes. Ao final, conclui-se que a legislação deixou de solucionar conflitos existentes em torno do tema, mantendo o cenário de insegurança jurídica aos empreendedores brasileiros, sendo, no entanto, necessário um maior tempo de vigência da lei para verificar o real impacto no fomento às atividades empresariais no país.
