Methodological provisions to the formation and the ensuring of efficiency and reliability of district-distributed heating systems
Authors: Stennikov V. A. , Postnikov I. V. , Mednikova E. E.
Published: December 2024

This study proposes a methodology for solving two problems of optimal development of district heating systems: analysis of efficiency areas and reliability of heat supply. In solving both problems, we adopt a nodal approach, which allows us to get detailed results that are most suitable to the real-world conditions. Based on the proposed methods and models, we develop an algorithm for transforming existing district heating systems into district-distributed heating systems with prosumers implemented into the network to serve the loads that fall outside the range of efficient operation of a district heating system. Wherein, the distributed sector is formed based on a prosumer that has its own generation, covering part of its own heat load and providing an additional functional and time redundancy for the system. As a result, conclusions and directions for further research are formulated.

Published: December 2024

A study on the neutralization of sulfur compounds during the filtration combustion of model mixture compositions containing iron sulfide or copper sulfate by adding marble (CaCO3) was carried out. It has been experimentally shown that during burning model charge compositions with additions of both iron sulfide and copper sulfate, replacing chemically inert sapphire with marble leads to a decrease in combustion temperature by approximately 150–200 °C. At the same time, the content of CO2 in gaseous products increases, and the concentrations of CO and H2 decrease. The greatest effect on the absorption of sulfur-containing substances when adding marble was shown in experiments where sulfur was present in the fuel in sulfide form: the addition of 50% marble made it possible to capture 72% of the initial sulfur content, and for compositions with 90% marble in the charge, 85%. The absorption of sulfur compounds formed during the combustion of model mixture compositions with copper sulfate is much worse. When the charge contains 50% and 85% marble, sulfur-containing compounds were absorbed by only 19% and 24%, respectively.
Potential of productive longevity of legum-mint grass mixture in the south of Western Siberia
Authors: Boyko V. S. , Timokhin A. Yu.
Published: December 2024

Perennial legume-bluegrass herbaceous stands stabilize forage production for highly productive livestock farming and make a significant contribution to the nitrogen balance of agroecosystems in Western Siberia. The studies were conducted to study the effect of mineral nutrition conditions on the growth, development and dry matter yield of a mixture of goat’s rue and brome grass in the forest-steppe of Western Siberia. The work was carried out in 2000…2021 in a stationary field experiment on meadow-chernozem medium-deep medium-humus heavy loamy soil in the Omsk region. The experiment was laid out in the hatchery field of the 8-field crop rotation (eastern galega, eastern galega + brome, spring barley, field pea, sweet sorghum, alfalfa + brome, forage beans, millet + rapeseed) according to the scheme providing for the study of the following options: potassium fertilizer (factor A) – K0, K60; nitrogen fertilizer (factor B) – N0, N30, N60; soil supply with mobile phosphorus (factor C) – average (70…80 mg/kg according to F. V. Chirikov, background 0), increased (background I – 120, background II – 140 mg/kg), high (150…160 mg/kg, background III). The most balanced ratio of legume and bluegrass components was on the backgrounds with increased and high content of mobile phosphorus in the soil. Without the application of nitrogen fertilizers against these backgrounds, the competitive ability of goat’s rue increases, which is ecologically and economically effective. Against the background of irrigation, the yield of the grass mixture reaches 8 … 9 t/ha of dry mass in variants with a sufficient level of phosphorus (increased and high content) at 6.35 t/ha without fertilizers. In subsequent years, in the absence of irrigation, the picture changed towards a general decrease in yield to 5 … 6 t/ha of dry mass in fertilized variants at 3.60 … 4.81 t/ha in the variant without fertilizers. In the second decade, a reliable manifestation of yield growth in variants without nitrogen fertilizers is by 0.49 in 2011 … 2015 and by 0.99 t/ha in 2016 … 2021 on average by factor, due to an increase in the share of goat’s rue in the botanical composition.

The relevance of the work is due to the need to increase the efficiency of sheep farming in the southern regions of Russia to improve food security and increase the production of high-quality meat. The purpose of the study was to evaluate the effect of crossing Edilbaevsheep with dorper sheep on the productive and biochemical parameters of young animals in the southern regions of Russia. During the study, three groups of animals were formed: purebred sheep of the Edilbaev breed (control group), mixed young with an equal proportion of blood (½ Edilbaev × ½ dorper, the first group) and young with a greater proportion of blood dorper (¼ Edilbaev × ¾ dorper, the second group). The results showed that the young of the second group demonstrated the highest indicators in terms of live weight and improved biochemical characteristics. The live weight in this group was 10.3 % higher (p0.05) compared to the control group. The total protein level in the second group was 110.89±10.86 g/l, which exceeded the indicators of the control group (105.68±5.33 g/l) by 4.9 % (p0.05). It was also revealed that the serum calcium content in the second group exceeded the values of the first group by 84.3 % (p0.001), which indicates an improvement in mineral metabolism. The analysis confirms that crossing with the dorper breed improves the productive and physiological parameters of young animals due to the pronounced effect of heterosis, especially in the case of half-blooded animals.

Published: December 2024

One hundred years ago, the serial production of the «Fordzon-Putilovets» wheeled tractor began at the «Krasny Putilovets» plant in Leningrad, which was a significant event in the history of machine building in the USSR. The start of production was preceded by the work of the Gosplan tractor commission, which was created to determine the tractor model and the enterprise for its production. (Research purpose) The research purpose is identifying the circumstances of the choice of the object and place of mass production of the tractor, determining the contribution of scientists to the work of the tractor commission; reflecting the importance of mass production in domestic engineering. (Materials and methods) Used sources reflecting the formation of tractor construction, archival materials of the V. P. Goryachkin Museum. Conducted research in accordance with the principles of historicism, scientific objectivity and reliability. (Results and discussion) It was shown that the process of initial tractorization of the country, in addition to purchases abroad and semiindustrial production of original designs, was also characterized by serial production of tractors according to foreign models. It was noted that the tractor «Fordzon» was recommended for mass production by the tractor commission of the State Planning Committee. The role of scientists V. P. Goryachkin and P. M. Belyanchikov, who organized the tests of the american tractor and determined its technical and operational characteristics, was revealed. The «Krasny Putilovets» plant was chosen as the place of mass production. (Conclusions) The tractorization of the country was carried out mainly due to the serial production of a tractor, the analogue of which was «Fordzon». Scientists V. P. Goryachkin and P. M. Belyanchikov were directly involved in the selection of this type of tractor. Its reproduction on «Krasny Putilovets» became possible thanks to the active position of the company’s management. The production of the Fordzon-Putilovets tractor contributed to the saturation of agriculture with traction machines, and the purposeful work on mastering the serial production of tractor equipment at the «Krasny Putilovets» plant marked the creation of the tractorbuilding industry in the USSR machine building.

ANALYSIS OF SKELLAM-TYPE MODELS WITH PERIODIC REGIMES
Authors: Matsenko V.
Published: December 2024

Difference equations are used in order to model the dynamics of population with non-overlapping generations. In the simplest case such equations have the form $N_{t+1}=f\left(N_t\right)N_t$, where $N_t>0$ is the population size at a moment of time $t$, $\displaystyle f\left(N_t\right)= \frac{N_{t+1}}{N_t}$ is a coefficient of natural reproduction.

In Skellam's model this coefficient has the form of a decreasing hyperbolic function: $\displaystyle f\left(N_t\right)= \frac{a}{b+N_t}$, $a,b>0$. Parameter $a$ here plays the role of the largest value of the reproduction coefficient, and $b$ describes the influence of self-regulating mechanisms on population dynamics.

For the Skellam's model, both without harvesting and with harvesting, only regimes with monotonic stabilization of the population size are observed. At the same time, as in other discrete models, there are periodic and even chaotic solutions.

In this work, the following generalization of the Skellam model is proposed, which allows the existence of periodic regimes.

Namely, a function is taken for $\displaystyle f\left(N_t\right)= \frac{a}{b+N_t^3}$. This shows that at certain values of $a$ and $b$ there are stable stationary states, that later lose stability, whereas with a corresponding change in $a$ and $b$, cycles of lengths 2, then 4, 8 appear. That is, there is a bifurcation of the doubling of the cycle.

Periodic solutions with period 3 where not found, although the existence of chaotic solutions was established. It has been established that stable periodic regimes during harvesting can lose their stability.
ON THE APPROXIMATION OF STOCHASTIC DELAY EQUATIONS IN INFINITE-DIMENSIONAL SPACES
Authors: Petryna G. , Stanzhytskiy O. , Martynyuk O.
Published: December 2024

The article presents a detailed scheme for the mean square approximation of evolutionary stochastic delay equations in infinite-dimensional spaces. The primary focus lies in substituting the original system with delay by a system of evolutionary stochastic equations without delay. The proposed approach involves partitioning the delay interval into subintervals and constructing a corresponding system of equations that approximates the original system's behavior. Notably, the number of equations in the approximating system grows as the number of partition subintervals increases. A significant result of this study demonstrates that, as the partitioning becomes finer (i.e., the number of subintervals approaches infinity), the mean square distance between the solutions of the delay equation and the solutions of the delay-free approximating system converges to zero.

The theoretical framework of the approximation method leverages key concepts and results from infinite-dimensional stochastic analysis, incorporating tools to address the challenges posed by the functional nature of the delay term and the unboundedness of the state space. The study not only generalizes earlier finite-dimensional results to the infinite-dimensional setting but also extends the methods used for deterministic delay systems to stochastic systems. The methodology builds on the classical idea of decomposing the solution of the delay equation using a Taylor expansion in terms of the delay length $h > 0$. This decomposition allows the construction of an approximating system that replaces the original delay equation with a system of Cauchy problems for ordinary differential equations (ODEs). The results have significant implications for practical applications, particularly for systems where delays naturally arise, such as in stochastic control, population dynamics, and infinite-dimensional systems described by stochastic PDEs. The ability to replace complex delay systems with delay-free approximations not only simplifies numerical computations but also provides insight into the underlying dynamics of these systems. By rigorously establishing the conditions under which the approximation is valid, this work contributes to the theoretical foundation of stochastic delay equations in infinite-dimensional spaces and offers a robust tool for analyzing and simulating such systems.
OPTIMAL CONTROL IN A BOUNDARY VALUE PROBLEM FOR 2B-PARABOLIC EQUATIONS WITH AN INTEGRAL NONLOCAL CONDITION
Authors: Pukalskyy I. , Yashan B.
Published: December 2024

The theory of optimal control of systems described by equations with partial derivatives is rich in results and is actively developing nowadays. The popularity of this kind of research is connected with their active use in solving problems of natural science, in particular, hydro- and gas dynamics, filtration, diffusion, heat physics, theory of biological populations.

The problem of choosing the optimal system control described by the boundary value problem for $2b$-parabolic equations with an integral non-local condition and limited internal, boundary and starting control is investigated. The quality criterion is given by the sum of volume and surface integrals. Using Green's function of the general boundary value problem for the $2b$ parabolic equation, the existence, uniqueness, and integral image of the solutions of the nonlocal boundary value problem for the $2b$ parabolic equation with the integral condition on the time variable have been established. Estimates of the solution of the nonlocal boundary value problem and its derivatives in H\"{o}lder spaces are found. The obtained results are used to establish the necessary and sufficient conditions for the existence of an optimal solution of systems described by a parabolic boundary value problem with a nonlocal integral condition for the time variable. The cases of limited internal, starting and boundary controls are considered.
SINGULAR FUNCTION RELATED WITH MARKOV REPRESENTATION OF NUMBERS
Authors: Serhiiko D. , Ratushniak S.
Published: December 2024

In this article, we introduce the three-symbol Markov representation of numbers, based on the decomposition of a number into the series \[x=\sum\limits_{i=0}^{\alpha_1-1}{q_i}+\sum_{k=1}^{\infty}\left({q_{\alpha_1}\sum\limits_{i=0}^{\alpha_k-1}{q_{\alpha_ki}}\prod_{j=1}^{k-1}{q_{\alpha_j\alpha_{j+1}}}}\right)= \Delta_{\alpha_1\alpha_2...\alpha_k...}, \alpha_k\in A=\{0,1,2\},\] where $\|q_{ij}\|$ is a positive stochastic matrix (transition probability matrix), and $(q_0;q_1;q_2)$ is a positive stochastic vector. This representation corresponds to thee classical ternary representation of numbers and coincides with it if $q_i=\frac{1}{3}=q_{ij}$ $\forall i,j\in A$. The topological and metric properties of the cylinders in this Markov representation are described. In particular, the basic metric ratio between the lengths of cylinders of the successive ranks is derived. Moreover, the concept of a Markov-normal number is introduced, and it is proved that the set of numbers for which the asymptotic frequency of each digit $i$ equals to $\sum\limits_{i\in A}q_jq_{ji}$, $i,j\in A$, has full Lebesgue measure. The function (inversor of numbers) is introduced and defined by the equality \[I(x=\Delta_{\alpha_1\alpha_2...\alpha_n...})=\Delta_{[2-\alpha_1][2-\alpha_2]...[2-\alpha_n]...}.\] It is proved that the function $I$ is a continuous, strictly decreasing function on the interval $[0;1]$. An expression for the derivative of the function $I$ at a point is foud based on the concept of a cylindric derivate. Using the normal property of a number in its Markov representation and the obtained expression for the derivative, conditions for the derivative to be zero at almost every point of the unit interval in the sense of the Lebesgue measure are established. Therefore, the conditions for the singularity of the function $I$ are determined.

Sociolinguistic Content in Training Courses: Pidgin Arabic and White Dialect for Bus Drivers
Authors: El Zahraa Fatima , Nawawi Mukhshon , Muttaqin Zainal
Published: December 2024

This study examined a gap in the company's manual book for Indonesian bus drivers assigned to work in Saudi Arabia. The manual book used formal Arabic vocabulary about bus parts, occupational safety, and traffic signs, while foreign workers from India, Pakistan, and Bangladesh frequently communicated in simplified Arabic. This discrepancy highlights the need to align training courses with the practical demands of daily interaction. The study employed a qualitative descriptive content analysis approach. The findings confirm Canagarajah's work on the importance of sociolinguistic competence in transnational work environments, Duggan's focus on the necessity of sociolinguistic awareness for migrants, and Kött and Vogl's research on the role native speakers play in acquiring hybrid Arabic. It supports Ubalde et al.'s findings on the impact of interethnic contact on language learning and aligns with Al-Rojaie's analysis of dialectal variations in Saudi Arabia. Furthermore, it agrees with Al-Mutayri and As-Susuwah's studies on pidgin Arabic. The study concludes the importance of equipping bus drivers with language variation in real-world communication and recommends incorporating sociolinguistic content into training courses to address multicultural work environment challenges.

У статті розглянуто фізіологічне зітхання як метод реабілітації для осіб із посттравматичним стресовим розладом (ПТСР), який стає особливо актуальним в умовах воєнного стану. Фізіологічне зітхання визначено як природну дихальну техніку, що сприяє активації парасимпатичної нервової системи, стабілізації емоційного стану, зменшенню тривожності та покращенню якості сну. Дослідження західних учених підтверджують його ефективність у роботі з різними категоріями постраждалих, включаючи військових, ветеранів та цивільних осіб. Простота, доступність і відсутність потреби у спеціальному обладнанні роблять цей метод універсальним для використання в індивідуальній і груповій терапії, а також у польових умовах. Результати досліджень свідчать про значний потенціал техніки для інтеграції в українську практику, що передбачає проведення локальних досліджень та адаптацію методу до соціокультурних потреб. У статті також запропоновано рекомендації для фахівців, спрямовані на впровадження фізіологічного зітхання як базового інструменту реабілітації в умовах масових психологічних викликів.

Published: December 2024

Стаття присвячена вивченню проблеми виникнення та розвитку подружніх конфліктів, а також виявленню основних чинників, що сприяють їх появі. В умовах соціально-економічних змін, які часто супроводжуються кризовими явищами в суспільстві, проблема сімейних конфліктів набуває особливої актуальності. У статті розглянуто ключові аспекти, що визначають природу сімейних суперечок, зокрема, складність комунікацій, різниця в цінностях, переконаннях та вихованні партнерів, а також зовнішні та внутрішні стресові чинники, що можуть погіршувати взаєморозуміння між подружжям.
Автор аналізує різні теоретичні підходи до класифікації сімейних конфліктів та наводять дані досліджень психологів, таких як В. Сисенко, С. Ковальов, Н. Грішина та інших, які підкреслюють роль конфліктів як природної складової взаємодії в сім’ї. Конфлікти можуть бути як негативними, так і конструктивними, оскільки вони часто створюють можливості для розвитку і зміцнення стосунків через відкриття нових шляхів взаєморозуміння та вирішення проблем.
Систематизовано причини виникнення конфліктів, зокрема: обмеження свободи дій, непорозуміння через різні уявлення про сімейні ролі, матеріальні труднощі, сексуальна дисгармонія, зрада, відсутність поваги, ревнощі та шкідливі звички. Водночас розглядається й етапність розвитку конфлікту, від латентної фази до кульмінаційної і завершальної стадії, з акцентом на роль емоцій та психологічних факторів у цей процес.
Окрему увагу приділено впливу зовнішніх факторів, таких як економічні труднощі, соціальний статус партнерів та загальний рівень стресу, що може погіршити взаємодію у родині. У статті також згадано про класифікацію конфліктів за різними параметрами, зокрема, залежно від суб’єктів конфлікту, джерел і поведінки учасників.
Метою роботи є поглиблене вивчення причин виникнення подружніх конфліктів та виявлення ефективних шляхів їх запобігання та подолання. Автор підкреслює що для гармонійного розвитку сімейних стосунків важливими є конструктивне спілкування, взаєморозуміння та здатність до адаптації в умовах кризових ситуацій.

Стаття присвячена темі впливу інформаційного середовища та Інтернету на формування самооцінки та ідентичності підлітків. У ній розглядаються процеси створення так званого інтернет – образу «Я», що формується під впливом соціальних мереж, онлайн-ігор та інших інтернет-ресурсів. У статті аналізується, як характеристики реального «Я» особистості переплітаються з віртуальними образами, які підлітки створюють для себе в мережі, і як це впливає на їхню поведінку в реальному житті. За результатами проведеного дослідження проаналізовано самоописи підлітків. З’ясовано, що значна частина сучасних підлітків описує себе через персонажів комп’ютерних ігор, субкультур та інші ролі, пов’язані з віртуальними реальностями.

Authors: ПОТАПЧУК Наталія , ВЕНДЕРА Алла
Published: December 2024

У статті здійснюється аналіз проблемних аспектів реалізації виховної функції дистантними сім’ями. Досліджено психологічні особливості дистантної сім’ї. З’ясовано, що найбільш гострими проблемами в процесі становлення особистості підлітка із дистантних сімей є тривала розлука з одним із батьків, дефіцит тілесно-емоційного спілкування з батьками, виникають часті конфлікти внаслідок відсутності активного спілкування, а також проблеми адаптації членів сім’ї до зустрічей та нових розлучень, труднощі в організації спілкування на відстані. Це провокує емоційне охолодження до потреби в батьківській любові та опіці, викликає почуття тривожності, дезадаптації та соціальної незахищеності.

Published: December 2024

This article explores the transformative journey of citizen participation in public affairs, focusing on the evolution from traditional public administration to contemporary e-governance frameworks. It highlights the shift towards New Public Governance (NPG), where citizens are seen as active partners rather than passive recipients of services. The study reviews various public administration models, including classic public administration, New Public Management (NPM), and modern e-governance and open government models, identifying four waves of government evolution. It emphasizes the role of digitalization in enhancing citizen engagement, drawing on international practices from countries like Japan, Norway, the UK, and others. The article categorizes citizen engagement into four stages, from passive consumers to smart citizens in the digital era, and discusses the demand and supply aspects of participation. It underscores the importance of digital infrastructure, ICT education, and international best practices in fostering effective citizen engagement. The study concludes with recommendations for future research on policy labs, e-participation, and local participation indexes, aiming to enhance citizen involvement in governance and public service delivery.

Transformers Can Navigate Mazes With Multi-Step Prediction
Authors: Nolte Niklas
Published: December 2024

Despite their remarkable success in language modeling, transformers trained to predict the next token in a sequence struggle with long-term planning. This limitation is particularly evident in tasks requiring foresight to plan multiple steps ahead such as maze navigation. The standard next _single_ token prediction objective, however, offers no explicit mechanism to predict multiple steps ahead—or revisit the path taken so far. Consequently, in this work we study whether explicitly predicting multiple steps ahead (and backwards) can improve transformers’ maze navigation. We train parameter-matched transformers from scratch, under identical settings, to navigate mazes of varying types and sizes with standard next token prediction and MLM-\(\mathcal{U}\), an objective explicitly predicting multiple steps ahead and backwards. We find that MLM-\(\mathcal{U}\) considerably improves transformers’ ability to navigate mazes compared to standard next token prediction across maze types and complexities. We also find MLM-\(\mathcal{U}\) training is 4\(\times\) more sample efficient and converges 2\(\times\) faster in terms of GPU training hours relative to next token training. Finally, for more complex mazes we find MLM-\(\mathcal{U}\) benefits from scaling to larger transformers. Remarkably, we find transformers trained with MLM-\(\mathcal{U}\) outperform larger transformers trained with next token prediction using additional supervision from A* search traces. We hope these findings underscore the promise of learning objectives to advance transformers’ capacity for long-term planning.

Published: December 2024

Fingerprint attendance is a biometric-based system that uses hardware, software, and databases to accurately record teacher attendance, offering a more efficient method compared to traditional attendance systems. This research aimed to explore the impact of fingerprint attendance on teacher work discipline at SDIT Nur Fatahillah, involving 20 teachers, consisting of 16 permanent foundation teachers (GTY) and 4 non-permanent teachers (GTT). The study employed a descriptive qualitative approach, with a random sampling technique. The findings indicated that the use of fingerprint attendance significantly improves teacher discipline by simplifying the attendance process, ensuring more accurate records, and fostering greater punctuality. Teachers expressed increased satisfaction with the system’s ease of use, which in turn boosted their sense of accountability. Moreover, the implementation of the system led to a noticeable improvement in teacher work discipline, as it encouraged teachers to adhere more closely to their working hours. The study also highlighted that the system provided benefits not only in terms of attendance accuracy but also in terms of enhancing teacher morale and job satisfaction. As a result, fingerprint attendance systems can be considered a valuable tool for educational institutions, promoting better teacher performance, administrative efficiency, and a more disciplined work environment, ultimately contributing to improved overall educational quality.
