Authors: Buhaievskyi Serhii , Nazarenko Iryna 
Published: December 2023

Problem. Nowadays, the cast reinforced concrete spans are widely used in the construction and rehabilitation of bridges. These structures are also proposed for small and medium spans by the DerzhDorNDI named after M.P. Shulgin. One of the disadvantages of the cast reinforced concrete slab spans is its heavy weight. Using polystyrene void foams allows to reduce the consumption of concrete and the own weight of the span structure to 30-45%. Self-compacting concrete belongs to the new generation of concrete and can be used in modern innovative construction including bridge designing. The manufacturing of the cast reinforced concrete slab spans using self-compacting concrete allows to significantly speed up the concreting process due to its placing in one stage. Goal.

Published: December 2023

Background: Several factors contribute to a student's academic performance. Studies have examined the direct impact of student-related factors and the broader influence of social and economic factors.
Objective: To identify the important factors influencing the academic performance of Master's level students at the Institute of Science and Technology (IoST), Tribhuvan University (TU).
Materials and Methods: Primary data of 251 master’s level students was collected with a questionnaire adapted and developed from similar studies. The data was collected using convenience sampling. In addition to demographic and categorical questions, five-point Likert scale questions were also used. Data analysis involved fitting a multiple linear regression (MLR) with the identified significant independent variables. The goodness of fit of the model was evaluated to assess the accuracy and reliability of the final model in explaining variations in students' SGPA (Semester Grade Point Average).
Results: The study revealed that students' motivation, study habits, and communication skills significantly influenced their SGPA. Study habits showed a coefficient of 0.118 (p < 0.001), indicating a positive and significant relationship with SGPA. Student motivation had a coefficient of 0.19 (p < 0.001). Similarly, Higher levels of motivation were linked to improved SGPA outcomes. Communication skills exhibited a coefficient of 0.086 (p < 0.001) at a 5% level of significance. All these factors had a positive coefficient which means students better on these factors on an average will tend to have better academic performance.
Conclusion: Study habits, motivation, and communication skills were found to have a significant effect on students’ SGPA. Therefore, we can conclude that at the master's level in IoST, TU, the primary determinants of students' SGPA are their characteristics such as their motivation, study habits, and communication skills.
BOUNDARY-VALUE PROBLEM FOR THE MULTI-TERM FRACTIONAL DIFFERENTIAL EQUATION WITH CAPUTO DERIVATIVE
Authors: Boichuk O. , Feruk V. 
Published: December 2023

The extensive application of fractional differential equations and boundary-value problems for these equations promotes the development of the theory and the appearance of numerous publications in this field. One of the types of such equations are equations containing more than one differential operator of fractional order.
This paper deals with the study of linear boundary-value problem for the multi-term fractional differential equation with the Caputo derivative. We considered the left fractional Caputo derivative, which is convenient for the description of systems with memory. The boundaryvalue problem is specified by linear vector functional such that the number of it components does not coincide with the number of the orders of the derivative. Assume that the coefficients of the equation are continuous functions and the orders of the derivative are commensurate. A multi-term fractional differential equation is reduced to an equivalent system of differential equations containing only one fractional operator. The general solution of the system of fractional differential equations consisting of a general solution of the associated homogeneous system and the arbitrary particular solution of the inhomogeneous system is considered. The particular solution we found, which is also a solution of the system of linear Volterra integral equations of the second kind with square summable kernels. The question of the solvability of the boundary-value problem for the multi-term fractional differential equations was studied. We considered the critical case, i.e. case when the homogeneous problem has nontrivial solutions. By using the theory of pseudo-inverse matrices, the necessary and sufficient conditions for solvability of the given problem are established. Moreover, a family of linearly independent solutions of this boundary-value problem is constructed.
COUNTABLE SPACES WITH PEANO PROPERTY

In 1890, Giuseppe Peano published an example of a continuous curve passing through every point of the square $[0,1]^2$. A curve with such properties is called a Peano curve. In fact, Peano constructed a continuous surjective mapping from the unit segment $[0,1]$ to the square $[0,1]^2$. Peano's research was motivated by one result of George Cantor that the set of points of a unit segment has the same cardinality as the set of points of a unit square.In 1890, Giuseppe Peano published an example of a continuous curve passing through every point of the square $[0,1]^2$. A curve with such properties is called a Peano curve. In fact, Peano constructed a continuous surjective mapping from the unit segment $[0,1]$ to the square $[0,1]^2$. Peano's research was motivated by one result of George Cantor that the set of points of a unit segment has the same cardinality as the set of points of a unit square. According to the Hahn-Mazurkevich theorem the Hausdorff topological space $X$ is a continuous image of a unit segment $[0,1]$ if and only if when $X$ is compact, metrizable, connected, locally connected and nonempty. The Hausdorff continuous image of a segment is called {\it Peano space} or {\it Peano continuum}. Sierpinski proved that a connected compact metric space $X$ is a Peano continuum if and only if for every $\varepsilon>0$ the space $X$ can be covered by connected sets of the diameter $\le\varepsilon$. Therefore, naturally arises question about the investigation of disconnected metric spaces $X$ for which there is a continuous surjection between $X$ and $X^2$. Sierpinski characterized rational numbers as a metric countable space without isolated points. Hausdorff described irrational numbers as a metric, separable, completely metrizable, zero-dimensional and nowhere locally compact space. It follows, in particular, that the square $\mathbb Q^2$ is a continuous image of the set $\mathbb Q$ and the square of irrational numbers is a continuous image of the set of irrational numbers. Thus, it would be interesting to find a description of other disconnected subsets of the real line, except those that are homeomorphic to $\mathbb Q$ or $\mathbb R\setminus Q$. In this article we will focus on countable sets such that the set of isolated points of which may not be empty. The main result is the following (see Theorem 2): the square of a countable regular topological space $X$ is its continuous image if and only if $X$ is not compact.
POST'S PSEUDO-DIFFERENTIAL OPERATOR IN S-TYPE SPACES
Authors: Litovchenko V. 
Published: December 2023

During the last few decades, the theory of fractional differentiation and pseudo-differential operators, which naturally generalize and extend the concepts of classical derivative and differential operations, has been rapidly developing. The reason for this development is primarily the close connection of pseudo-differential operators and fractional differentiation with important problems of analysis and modern mathematical physics. It turned out that such player operators play an important role in the theory of analytical boundary-value problems (in the study of the index of the problem, in reduction to the boundary of the region, etc.), in microlocal analysis, in the theory of random processes, with the help of fractal differentiation operators heat-diffusive processes in porous media, etc. There are different approaches to the generalization of the classical derivative, the implementation of which gave rise to a variety of fractional differentiation and pseudodifferentiation operations. In this connection, there is a natural need for a comparative characterization of these generalizations, which is convenient to conduct through the prism of the classical form of fractional differentiation on elements with "sufficiently good" properties. In addition, the representation of this or that pseudo-differentiation operation in such a classical form makes it possible to use a rather convenient Fourier transform apparatus for the analysis of problems with these operations. In this work, the question of the possibility of representation in S type spaces of I.M.

ON SOME PROPERTIES OF THE DIGIT SHIFT OPERATOR Q_s^*-REPRESENTATION OF REAL NUMBERS AND UNIFORMLY DISTRIBUTED SEQUENCES PRODUCED BY IT
Authors: Skakun D. , Kryvoshiya R. 
Published: December 2023

The work is devoted to the study of the properties of the left-shift operator $Q_{s}^{*}$-representation of real numbers and the study of the type of distribution of the sequences produced by the corresponding operator. The $Q_{s}^{*}$-representation of real numbers is a natural generalization of the classical s-representation and is topologically similar to the latter. E. Borel's classic result that almost all numbers are s-normal was over time translated into the terms of uniformly distributed sequences produced by the left-shift operator of the digits of the corresponding representation. It was proved that a number is s-normal only when the corresponding sequence generated by this number in the sense of the left shift operator is uniformly distributed. Despite the topological similarity between the $Q_{s}^{*}$-representation of real numbers and the classical s-representation, proving similar results for the former requires fundamentally new approaches that include the use of the apparatus of ergodic theory. The absence of the effect of metric transitivity of the appearance of digits, which is characteristic of the classical s-representation, does not allow the use of appropriate approaches to the $Q_{s}^{*}$-representation. The construction of normal numbers in various representation systems is a separate non-trivial problem and is the subject of many studies. In many cases, criteria for the normality of numbers, which can have a continuous structure (similar to the classical criteria of uniform distribution of the sequence) or a discrete structure, are useful for constructing the corresponding numbers. This paper presents generalizations of discrete criteria for the normality of numbers, which applied both to the classical s-representation and to the $Q_{s}$-representation of real numbers (the latter is a partial case of the $Q_{s}^{*}$-representation).
Comparison of the bearing capacities of a small-diameter bored pile obtained from the results of field tests and numerical modeling
Authors: Soroka Pavlo 
Published: December 2023

Abstract. The paper compares the results of modeling static soil tests with a small-diameter drill pile with the data obtained from field tests. The calculations were performed by numerical modeling using the PC software "Plaxis", which is based on the finite element method. This problem was solved in a flat (2D) formulation for an axisymmetric model, which makes it possible to analyze the stress-strain state (SSS) and the interaction of elements of the pile-soil environment system.
Separate computational models were created for two types of piles made using different technologies: a bored- CFA pile and a drilled pile with partial soil displacement. In order to take into account the preload history in order to maximize the models' approximation to real conditions, the calculations were performed in 4 stages in accordance with the construction sequence: Stage 1 - initial stage (determination of the initial stresses in the soil massif in the natural state), Stage 2 - excavation to the design mark of the pit bottom, Stage 3 - testing of the soils with a pile by static load. Stage 4 - pile unloading. Based on the results of the calculations, the SSS and the interaction of the elements of the "pile-soil environment" system have been analyzed and compared the settlement graphs obtained from the results of the calculations with the data of field tests.
It is shown that the use of a plane axisymmetric FEM is a sufficiently effective approach for assessing the stress-strain state and understanding the interaction of elements of the pile-soil system, as well as predicting the bearing capacity of piles for further design of the pile foundation before obtaining the results of field tests. In addition, the labor intensity and time consumption of this approach are relatively low compared to other alternative methods.
With appropriate experience in using this approach in different soil conditions with appropriate comparison with field test data, it can be applied in the feasibility study and final decisions on the choice of a particular type of foundation.

Published: December 2023

Актуальність. В умовах повномасштабної російської агресіїгромадяни України змушені адаптуватись до нових реалій і шукати моделі соціально-економічної поведінки, які б забезпечили виживання і розвиток.
Метою статті є обґрунтування методологічних засад соціально-психологічного прогнозування економічної поведінки українців.
Результати. Встановлено, що розроблення ефективних прогнозів ускладнюється а) різноплановістю методологічних підходів та класифікаційних моделей економічної поведінки, б) низькою валідністю результатів емпіричних досліджень, які ґрунтуються на різних критеріальних моделях; в) багатовекторністю детермінації економічної поведінки. Запропоновано робоче визначення економічної поведінки як сукупності виборів щодо економічних цілей та способів їх досягнення, що ґрунтуються на світоглядних уявленнях та настановленнях особистості (групи, спільноти). Виокремлено соціально-психологічні чинники економічної поведінки, які підлягають емпіричному вимірюванню: мотиваційні (мотиви прийняття економічних рішень, рівень усвідомлення своїх інтересів і можливостей, наявний досвід реалізації прийнятих економічних рішень та досягнення цілей); ставленнєві (толерантність до корупції, ставлення до грошей, законослухняність); компетентнісні (ступінь економічної обізнаності, здатності: планувати економічне майбутнє і кроки по його досягненню, приймати економічні рішення в умовах невизначеності, передбачати наслідки своїх рішень; готовність змінюватися задля підвищення рівня свого економічного добробуту); рефлексивні (ідентифікація себе як учасника економічної взаємодії, практики аналізу причин власних невдач і здобутків, оцінювання власного потенціалу щодо прийняття економічних рішень). Визначено етапи соціально-психологічного прогнозування та перелік методів, які доцільно застосовувати на кожному з них.
Висновки і перспективи подальших досліджень Прогностичні сценарії можуть бути побудовані на основі критеріальної моделі чинників економічної поведінки, визначення необхідних і достатніх показників та індикаторів.
