Published: January 2022

Introduction. The paper submits the analysis of existing design solutions of flow dividers used to synchronize hydraulic drives of working bodies of technological and mobile machines. The market demands for multithreaded throttle flow dividers without valves with the controlled division ratio, such as multi-axle vehicle chassis, are identified. The objective of the work was to analyze the possibility and rationale for developing a throttle four-way flow divider without valves with sensing elements of the Venturi tube type. The solution should provide the synchronicity of movement (rotation) of more than three working bodies of technological and mobile machines.

Materials and Methods. A patent search for the designs of hydraulic flow dividers is carried out, and systems that require the division of the hydraulic fluid flow into more than two executive bodies are considered. An upgrade option, which allows dividing the flow into four branches, is proposed for the design of a three-channel throttle flow divider without valves.

Results. The urgency of developing a multithreaded throttle flow divider without valves for application in industrial and mobile machines is validated. Two types of four-flow dividers are considered, their weaknesses are indicated. It is noted that the development of a multithreaded throttle flow divider based on the designs created in 1989 and 1991 will reduce the number of hydraulic pumps and get rid of the series connection of double-flow dividers. In this way, it is possible to reduce pressure losses in the hydraulic system and implement adaptive control of hydraulic motors of multi-motor mobile machines. The possibility to obtain a divider/combiner into four flows by adding an outlet chamber connected to the membrane chamber through a channel entering the Venturi nozzle on the basis of a three-flow throttle divider is shown. The principle of operation of such equipment is described.

Discussion and Conclusions. The principles of construction of throttle flow dividers without valves are considered. An upgrade option is proposed to increase the number of division channels from three to four. However, to validate the operability of this design, a numerical analysis of the various modes of operation of the divider is required — calculation of the reduced volumetric stiffness of its working cavities. The information obtained can be used to modernize the hydraulic units of technological and mobile machines, increase their reliability, manufacturability, and efficiency. The issues that need to be solved in further research are identified.
Machine Learning and data mining tools applied for databases of low number of records
Authors: Anysz Hubert
Published: January 2022

The use of data mining and machine learning tools is becoming increasingly common. Their usefulness is mainly noticeable in the case of large datasets, when information to be found or new relationships are extracted from information noise. The development of these tools means that datasets with much fewer records are being explored, usually associated with specific phenomena. This specificity most often causes the impossibility of increasing the number of cases, and that can facilitate the search for dependences in the phenomena under study. The paper discusses the features of applying the selected tools to a small set of data. Attempts have been made to present methods of data preparation, methods for calculating the performance of tools, taking into account the specifics of databases with a small number of records. The techniques selected by the author are proposed, which helped to break the deadlock in calculations, i.e., to get results much worse than expected. The need to apply methods to improve the accuracy of forecasts and the accuracy of classification was caused by a small amount of analysed data. This paper is not a review of popular methods of machine learning and data mining; nevertheless, the collected and presented material will help the reader to shorten the path to obtaining satisfactory results when using the described computational methods

Published: January 2022

Introduction. This paper studies the capability of different types of artificial neural networks (ANN) to predict the modulus of elasticity of pavement layers for flexible asphalt pavement under operating conditions. The falling weight deflectometer (FWD) was selected to simulate the dynamic traffic loads and measure the flexural bowls on the road surface to obtain the database of ANN models.

Materials and Methods. Artificial networks types (the feedforward backpropagation, layer-recurrent, cascade back- propagation, and Elman backpropagation) are developed to define the optimal ANN model using Matlab software. To appreciate the efficiency of every model, we used the constructed ANN models for predicting the elastic modulus values for 25 new pavement sections that were not used in the process of training, validation, or testing to ensure its suitability. The efficiency measures such as mean absolute error (MAE), the coefficient of multiple determinations R2, Root Mean Square Error (RMSE), Mean Absolute Percent Error (MAPE) values were obtained for all models results.

Results. Based on the performance parameters, it was concluded that among these algorithms, the feed-forward model has a better performance compared to the other three ANN types. The results of the best four models were compared to each other and to the actual data obtained to determine the best method.

Discussion and Conclusions. The differences between the results of the four best models for the four types of algorithms used were very small, as they showed the closeness between them and the actual values. The research results confirm the possibility of ANN-based models to evaluate the elastic modulus of pavement layers speedily and reliably for using it in the structural assessment of (NDT) flexible pavement data at the appropriate time.

Published: January 2022

The establishment of the K-12 curriculum has had a significant impact on subject requirements related to the outcome-based education plan and the requisite output for a given research report or requirement. Social networking platforms enable students to effortlessly complete a variety of tasks, such as learning and performance. By intervening in research, social networking sites break down the barriers that limit both students and teachers in the research process. Three methodologies or ideas have arisen, known as approaches, that could help you facilitate teaching research, even if you are not in the research discipline: the Facebook-Personality Network Approach, the Virtual Research Journal, and the Google Immersion Approach. It is considered favorably by some students and users, but there are those who take advantage of its negative aspects. Instead of focusing on the emerging ideas or topics created by coding, I used social networking sites to demonstrate that research can be done anytime, anyplace, for any purpose or cause. According to the outcome-based education paradigm, students found the three techniques highly engaging. In order to be a teacher-researcher, you must utilize your originality and resourcefulness when it comes to all of the resources, devices, and technology, as well as the available social networking sites.

Interest in reading is the emergence of feelings of pleasure or strong interest that encourages individuals to carry out activities so that they do it on their own accord. Then there are attempts to do this activity repeatedly. reading is an important activity. Human civilization will not be far from this activity. Even in its history, a civilization is said to be advanced if humans at that time had the ability to read and write. Even in Islam, the first commandment to the Prophet Muhammad was to read (iqra`: read). It has also been proven, a nation with a high interest in reading becomes a nation that excels in science and technology. By reading, you can find a variety of knowledge and make discoveries in both the scientific and social fields. Based on research on reading interest, broadly speaking, there are two factors, namely internal and external factors. Internal factors generally include perceptions, motivations, and individual feelings towards reading activities. Meanwhile, external factors relate to the environment, ease of access to books, availability of facilities and infrastructure, technological developments, and even distribution of reading books. Therefore, a unique literacy is needed to support the reading culture of the community. Literacy has an important role in the life of a learning community that lives in an era that is based on current knowledge, technology, and information. Human civilization can be awakened by mastery of literacy based on reading, writing, and critical thinking activities. Literacy is a process of how a person communicates in society. In addition, literacy can also be interpreted as practice and social relations related to knowledge, language, and culture. Libraries with librarians can be used to develop a literacy culture for users in particular and society in general. With the available resources, together with stakeholders and community groups, they can innovate, create, and vary literacy-based library services. Thus the literacy culture will grow and develop.

Multi-Output Regression for Analyzing Power System Random States in Reliability Assessment by the Monte Carlo Method
Authors: Boyarkin D. A.
Published: January 2022

Increasing calculation speed of the electric power system (EPS) reliability of is one of the key issues in their operational management and long-term development planning. Analytical methods to assess the EPS reliability seem to be impossible due to large size of the problem and, as a consequence, essentially the only option for assessing is to use the Monte Carlo method. When it is used both the speed and the accuracy of calculation directly depend on the number of randomly generated system states and the complexity of their calculation in the model. Methods aimed at increasing computational efficiency can relate to two directions - reducing the states under consideration and simplifying the computational model for each state. Both options are performed provided that calculation accuracy is retained.

The article presents research on using the machine learning methods and, in particular, the multi-output regression method to modernize the reliability assessment technique via the Monte Carlo method. Machine learning methods are used to determine the power deficit (realization of a random variable) for each random EPS state.

The use of multi-output regression enables comprehensive determining of values of all the required variables. The experimental studies are based on the two test circuits of electric power systems: three-zone and IEEE RTS-96 with 24 zones of reliability.
Modal Analysis Problem Solution for a Mathematical Model Formed by the Extended Nodal Method
Authors: Trudonoshin V. A. , Ovchinnikov V. A. , Fedoruk V. G.
Published: January 2022

The article proposes an option for transforming a mathematical model of the object, formed by the extended nodal method in the time-domain solution for modal analysis. Since finding the eigenvalues ​​and eigenvectors for systems of ordinary equations given in the Cauchy normal form is possible, calculations are presented that allow us to obtain a system of equations in the Cauchy normal form from a mathematical model in a differential-algebraic form through linearization. The extended nodal method contains derivatives of state variables in the vector of unknown, and the Jacobi matrix obtained at each Newton iteration of each step of numerical integration can be used to obtain a linearized mathematical model, but the equilibrium equations, as a rule, contain several derivatives with respect to time. By introducing additional variables, it is possible to reduce the linearized mathematical model to the Cauchy normal form, while the Jacobi matrix structure remains essentially unchanged.

The proposed solution is implemented in the mathematical core of the PRADIS Gen2 PA-8 software package, which made it possible to expand its functionality by an operator of modal analysis.

The presented calculations of test schemes have shown the correctness of the method proposed.
Efficiency Analysis of OLAP-data Hypercube Decomposition for Exponential Computational Complexity Methods
Authors: Nosov A. P. , Akhrem A. A. , Rakhmankulov V. Z.
Published: January 2022

The paper studies problems of reduction (decomposition) of OLAP-hypercube multidimensional data models. When decomposing large hyper-cubes of multidimensional data into sub-cube components the goal is to increase the computational performance of analytical OLAP systems, which is related to decreasing computational complexity of reduction methods for solving OLAP-data analysis problems with respect to the computational complexity of non-reduction methods, applied to data directly all over the hypercube. The paper formalizes the concepts of reduction and non-reduction methods and gives a definition of the upper bound for the change in the computational complexity of reduction methods in the decomposition of the problem of analyzing multidimensional OLAP-data in comparison with non-reduction methods in the class of exponential degree of computational complexity.

The exact values of the upper bound for changing computational complexity are obtained for the hypercube decomposition into two sub-cubes on sets consisting of an even and an odd number of sub-cube structures, and its main properties are given, which are used to determine the decomposition efficiency. A formula for the efficiency of decomposition into two sub-cube structures for reduction of OLAP data analysis problems is obtained, and it is shown that with an increase in the dimension “n” of the lattice specifying the number of sub-cubes in the hypercube data structure, the efficiency of such a decomposition obeys an exponential law with an exponent “n/2”, regardless of the parity “n”. The examples show the possibility to use the values (found) of the upper bound for the change in computational complexity to establish the effectiveness criteria for reduction methods and the expediency of decomposition in specific cases.

The paper results can be used in processing and analysis of information arrays of hypercube structures of analytical OLAP systems belonging to the Big-Data or super-large computer systems of multidimensional data.
Mathematical Modelling of the Elliptical Vortex Ring in a Viscous Fluid with the Vortex Filament Method
Authors: Kotsur O. S.
Published: January 2022

The article deals with modelling an elliptical vortex ring in a viscous fluid using the Lagrangian vortex filament method. The novelty is that earlier only inviscid flows restricted vortex filament method application. The proposed viscosity model uses an analogue of the diffusion rate method, which is widely applied to simulate plane-parallel and axisymmetric flows of viscous fluid. A transfer of the formula of a diffusion rate from two-dimensional flows to the model of spatial vortex filament is due to assumption that swirling of vortex lines (helicity of vorticity) is unavailable. Despite the laxity of the diffusion rate model for general spatial flows, its application enables taking into account the effect of viscous diffusion of vorticity, which provides expansion of vortex tubes in space. The paper formulates the vortex filament method in which the filaments are broken into the vortex segments. Such discretization enables turning from the equation of vorticity evolution in partial derivatives to a system of ordinary differential equations with respect to the parameters of the segments. Formulas to calculate a filament system-induced flow rate as well as formulas to perform approximate calculation of an analogue of the diffusion rate are given.

The objective is to propose the viscosity model as an application to the vortex filament method by the example of modelling the evolution of an elliptical vortex ring in viscous fluid. The calculation results obtained by the vortex method are compared with the existing experiment and with the calculation performed by the grid method in the OpenFOAM package. A feature of the problem is that there are zones of nonzero helicity of vorticity where the proposed model of viscosity, strictly speaking, is not correct. It is shown that the results of calculations are in good agreement with each other and are in complete agreement with experiment. This allows saying that the effects of swirling vortex lines do not significantly affect the results of modelling a specific example of the spatial flow of viscous fluid by the proposed modification of the vortex filament method.
Anti–crisis Mechanisms of Qatar: Economic Diversification, Digitalization, Transformation
Authors: Babenkova S. Yu.
Published: January 2022

The Qatar National Vision 2030 program is based on two principles — modernization and preservation of traditions. Blockade of the country in 2017–2020 and the coronavirus pandemic became a serious test for the economy of Qatar, but the government and residents of the country do not consider themselves defeated by these circumstances, but on the contrary, these circumstances helped the country’s economy to survive the above crises. In 2019, the International Monetary Fund said that Qatar’s economy was resilient in the face of the blockade and shocks caused, including by the fall in hydrocarbon prices in 2014–2016. The events of the global economic crisis caused by the pandemic have posed another challenge to the financial and banking system of Qatar. Thanks to the measures of the country’s government aimed at ensuring business continuity, maintaining liquidity and providing support to the sectors of the economy affected by the pandemic, it was possible to mitigate the impact of this shock, support cash flows, and achieve financial and banking stability in the country. However, according to fund analysts, COVID–19 and a sharp drop in hydrocarbon revenues will lead to a reduction in real GDP growth by 2% in 2020. At the same time, future profits from hosting the FIFA World Cup in 2022, continued expansion of capacities in production of liquefied gas and competent fiscal and monetary policy will contribute to economic growth in the country in the medium term.
The Impact of Ideologies on the Translator’s Work: A Conceptual Reflection and Application
Authors: Kuzderová Henrieta , Bednárova-Gibová Klaudia
Published: January 2022

This paper addresses the translator’s role from an ideological standpoint and seeks to show that the actions of translators are not completely arbitrary and may be influenced by a wide array of factors and especially ideologies. The basic assumption is that translators can detach texts neither from the ideologies of the source nor the target culture. This study results from qualitative research, namely a critical conceptual analysis of the selected theories of translation studies (Baker, 2006; Lefevere, 1992; Venuti, 1995). The conceptual reflection implies that translations serve as an infinite source of culture and history, serving the target but not the source culture. The critical discourse analysis of English translations of two selected novels that contain the ideologies of socialist and post-socialist era, and the Nazi ideology, suggests that the tendencies in translation strategies vary depending on diffusion of the languages, and awareness of the target culture and history.
Technology solutions for interpreters: the VIP system
Authors: Corpas Pastor Gloria
Published: January 2022

Interpreting technologies have abruptly entered the profession in recent years. However, technology still remains a relatively marginal topic of academic debate, although interest in developing tailor-made solutions for interpreters has risen sharply. This paper presents the VIP system, one of the research outputs of the homonymous project VIP - Voice-text Integrated system for interPreters, and its continuation (VIP II). More specifically, a technology-based terminology workflow for simultaneous interpretation is presented.
Fé cristã, racionalidade e o “sentido do mundo” 20 anos após o 11 de setembro
Authors: Boareto José Antonio
Published: January 2022

Vinte anos após o 11 de setembro, faz-se necessário refletir acerca das consequências deste acontecimento para todo o globo. O “sentido do mundo” dado pela fé cristã e pela racionalidade ocidental, ainda que permaneça como preponderante, precisa reconhecer a emergência de outras duas culturas: a asiática e a islâmica. A interculturalidade, segundo Joseph Ratzinger, coloca-se como exigência para a convivência plural. Na atual política internacional do Papa Francisco, em seu empenho por uma cultura do encontro e do diálogo, é possível verificar em suas atitudes, gestos que demonstrem a importância da aproximação entre ocidente e oriente protagonizados pelo catolicismo e islamismo.

In the Footsteps of Graphicons: Tracing Parameters and Pragmatic Strategies in Graphicon Usage
Authors: Vishogradska-Meyer Ina
Published: January 2022

The textual intercourse in computer-mediated communication is intertwined with graphicons of various forms, gaining new meanings and functions. They are part of the online culture and, specifically, part of the communicative skills in digital environment. In many cases, graphicons are used not as signs of emotion but rather as indication of the illocutionary force of the textual utterances that they accompany. The current work endeavours to reveal the specific aspect of language use where iconoid objects “take over” and substitute textual utterances. The paper also attempts to trace to what extent pragmatics could be applicable in the analysis of the visual representations (i.e. graphicons) embodied in computer-mediated communication as means of communicative acts. The different graphicon forms and the dynamics in the usage carry additional challenge for the interpretation of the “visual” act. However, it is possible to systematically trace a pattern in the occurrence of the graphicons – their use as a complementary to a written statement, and their use as a single communicative act.
Suicidal ideation, plans, and attempts and the use of psychoactive substances by adolescents
Authors: Pawłowska Beata , Szymańska Jolanta
Published: January 2022

Introduction: Suicidal behavior and substance abuse constitute a serious public health problem.

Aim: The study was to analyze the relationships between suicidal behaviors (ideation, plans, attempts) and substance abuse in adolescents. The authors also took into account the respondents’ motivation to attempt suicide and use psychoactive substances, as well as some demographic variables.

Participants: The study involved 3493 secondary school students aged 16-17 years. The group included 69.41% girls and 30.59% boys.

Methods: The participants were surveyed with a self-report questionnaire designed by one of the authors.

Results: Statistically significant relationships were found between the respondents’ suicidal behaviors and the risky use of alcohol, cannabis, amphetamine, and designer drugs.

Conclusions:

1. The use of psychoactive substances increases the risk of suicidal ideation and plans, as well as suicidal attempts in adolescents and young adults.

2. Significantly more respondents who report suicidal ideation, plans and attempts, in comparison to those who do not report such thoughts and behaviours, abuse alcohol and consumer cannabis, amphetamine and designer drugs to cope with problems and olster self-confidence.

3. In the group of respondents who report suicidal behaviour, psychoactive substances are consumed by significantly more men than women and by significantly more city inhabitants than people living in the country.

4. Young people, who report suicidal thoughts, plans, and attempts, are initiated into alcohol consumption at an earlier age than their non-suicidal peers.
