Polskie epizody w tzw. sprawie Hansa Davida z Miłakowa. Przyczynek do sposobu fałszowania dokumentów w trzeciej i czwartej dekadzie XV wieku
Authors: Szweda Adam , Jóźwiak Sławomir
Published: January 2025

Przedmiotem artykułu są wybrane aspekty sporu Hansa Davida z Miłakowa z zakonem krzyżackim w Prusach. Wysuwał on roszczenia finansowe bazujące na rzekomych długach zakonu wobec jego rodziców – Davida i Cecylii z Miłakowa. Konflikt ten przerodził się w wieloletnią batalię prawną, rozgrywającą się przed różnymi instancjami. Miał on również swoje polskie wątki, ponieważ Hans David utrzymywał kontakty z władzami i mieszkańcami Poznania, był obywatelem Nowej Nieszawy (pod Toruniem), bywał też na polskim dworze królewskim. Pruski mieszczanin w swej działalności nie stronił od fałszowania źródeł. Analizowany materiał dostarcza szeregu informacji w tym zakresie. Z pergaminów usuwano dotychczasowy tekst i wpisywano nowy, przewieszano pieczęcie, pojawia się nawet informacja, że Hans David własnoręcznie wykonywał typariusz pieczęci. Fałszowane akty nie odnosiły się tylko do meritum sporu pruskiego mieszczanina z Krzyżakami, albowiem po przywieszeniu pieczęci królowej Zofii pozyskanej z wystawionego przez nią dokumentu Hans David miał sfałszować „zaświadczenie”, że jest dworzaninem polskiej władczyni. Ten oraz pozostałe aspekty sprawy Hansa Davida zasługują na kompleksowe opracowanie, co wymaga zebrania, a przede wszystkim usystematyzowania obszernego i bardzo rozproszonego materiału odnoszącego się do tego zagadnienia.
Supliki z diecezji przemyskiej do Penitencjarii Apostolskiej z XV wieku na tle porównawczym
Authors: Saczyńska-Vercamer Monika
Published: January 2025

Przedmiotem artykułu jest grupa ok. 30 suplik z diecezji przemyskiej z XV wieku, jakie zachowały się w archiwum Penitencjarii Apostolskiej. Diecezja przemyska jest szczególnie ciekawym obszarem badawczym z uwagi na zróżnicowaną pod względem wyznaniowym ludność zamieszkującą jej teren, współistnienie prawosławnej organizacji kościelnej, a także bliskie związki (geograficzne, osobowe) z Małopolską. Była też obszarem misyjnym Kościoła katolickiego. Liczba suplik z diecezji przemyskiej, najmniejszej spośród diecezji arcybiskupstwa lwowskiego – niecałe 30 – jest bardzo mała w porównaniu z diecezjami arcybiskupstwa gnieźnieńskiego, ale znacząca (największa) w skali lokalnej metropolii. Trzeba w tym widzieć wynik właśnie bliskich związków z metropolią gnieźnieńską, ale nie bez znaczenia było oddziaływanie (transfer kulturowy, kaznodziejstwo, dbałość o szkołę katedralną) środowiska kapituły katedralnej, w której nie brak było wybitnych osób, jak np. Mikołaj Wigand. Supliki z diecezji przemyskiej obrazują prawie pełną skalę uprawnień urzędu obsługującego rezerwaty papieskie. Widoczne są zarówno zjawiska szersze (np. elitarne przywileje papieskie), jak i specyfika lokalna (np. nieprawidłowości w sprawowaniu kultu, specyficzne rozumienie przeszkód małżeńskich). Jednocześnie pozwalają one obserwować funkcjonowanie prawa kanonicznego na obszarze leżącym nie tylko na peryferiach Kościoła zachodniego.
“This Is Not America”: Restagings of the Cold War through Embodied Memory
Authors: Grimaldi Anna
Published: January 2025

This paper explores resonances of Cold War resistance to dictatorship in Latin America in the work of Puerto Rican activist and artist, Residente. By analysing a music video, This Is Not America, released in early 2022, I explore the ways in which political projects of the Cold War are brought to life through embodied performances of memory. In the video, bodies reinforce a shared political subjectivity by choreographing and performing social struggles from across the continent since its invasion and colonisation in the 16th century, with a particular focus on the Cold War period. The video’s conceptualisation of the Latin American struggle is defined through shared historical experiences of oppression, regional heroes and martyrs, and decolonial Latin American and Global South-driven visions for the future. In bringing certain bodies of the past to life and into dialogue (or not) with the present, the video positions the prefigurative political visions of more recent Latin American social movements within a longer history and genealogy.

Calibrating density functionals with DMol3 applied on lithium oxide battery
Authors: Pacheco-Sánchez Juan Horacio , Vera García A. , Desales Guzmán L. A. , Zaragoza I.-P.
Published: January 2025

Density functional theory - based methods constitute part of the computational techniques considered for finding energy, temperature, pressure, density, electronic structure, and more, of materials and other systems. There is not a general density functional for solving either one or another system, rather there are approximations to the exchange-correlation functional designed to apply this theory, and the density functional for the system in study is usually selected through the Jacob’s Ladder. The purpose of this article is to calibrate by means of selecting multiple density functionals, for calculating potential energy curves on a specific system, and comparing these results with literature values to determine the most suitable functional. With this theory, when a calculation becomes cyclical means that it does not converge after thousands of steps or iterations. The use of thermal smearing calculations can achieve the convergence of the molecular systems. The density functional is calibrated at insignificant thermal smearing values (around 0.005 Hartrees), because the calculated minimum energy is still consistent against experimental values. This level of theory allows searching for stable reaction products. Among the interactions developed to find a suitable density functional are Li + O, Li + O2, Li + CO, 2 LiO– + C38H8.  We select GGA-PBE-Grimme as the most suitable density functional. The resulting information is for applying it to infer about charge/discharge of a rechargeable battery, according to the porosity of the cathode.

Published: January 2025

In this study, Raman spectra of Brazil nut oil were collected through a frying process at temperatures ranging from 50 °C to 250 °C, and of oleic acid at room temperature to compare their respective vibrational bands. The theoretical and scaled Raman frequencies of the oleic acid structure were obtained with the Density Functional Theory, employed using the basis set of the 6-311G+(d,p) Gaussian type orbital and the B3LYP functional. Experimental results reveal subtle changes in the spectra of Brazil nut oil from 210 °C onwards, characterized mainly by a decrease in the Raman signal and broadening of certain bands, such as those observed at 1746 cm-1, 2726 cmcm-1 and 3012 cmcm-1. At temperatures around 230 °C to 250 °C, Brazil nut oil undergoes advanced thermal degradation. The linear fit data demonstrate a linear relationship between the Raman signal and temperature increase, with R2 values of 0.999 and 0.977, for some bands. The Density Functional Theory method proved to be useful in predicting oleic acid spectra and vibrational signatures were assigned with the help of the VEDA program. This work highlights the potential of Raman spectroscopy to detect changes in Brazil nut oil during frying.
Electromagnetic field induced resonance tunneling in a quantum point contact
Authors: González de la Cruz Gerardo
Published: January 2025

Recently experimental results described electron transport through a quantum point contact irradiated by an electromagnetic wave in the tunneling regime as a photon-stimulated tunneling. In this work, we study electron tunneling through potential barrier in the presence of an intense electromagnetic field. Using the time-dependent unitary transformation method, the electron scattering by the laser-dressed potential barrier is calculated analytically. It is shown that the potential barrier is modified in the presence of the electromagnetic radiation and electron transmission probability is enhanced with increasing the laser-field strength.

Authors: Galindo Yovani , Gómez-Heleria Delmer , Núñez González José , Bustamante Carlos A.
Published: January 2025

This work focuses on the design of a new griddle-type biomass stove with an internal cross-flow configuration. For this purpose, numerical simulations of the heat transfer and fluid flow in the stove have been carried out. In particular, the equations corresponding to the momentum, energy, and chemical species are solved to determine the influence of the geometrical design. Temperature and isothermal contours on the surface of the griddle were presented. Various stove designs with firepower settings ranging from 10 to 16 kW were investigated. The findings revealed a decrease in thermal efficiency with increasing firepower, which was attributed to higher convective losses. Based on the numerical results, a cookstove prototype was manufactured. Furthermore, the thermal efficiency of the stove was evaluated using the WBT protocol. The goal of this research is not only to assess the thermal performance of the developed technology but also to provide a real-world example of the adoption process of a new technology designed for rural communities.

Published: January 2025

Semiconductor compounds are a fascinating type of materials that have attracted the attention of scientists because of their ability to enhance green technology by efficiently converting, storing, and transmitting waste heat into electrical energy. This research aimed to investigate the structural, electronic, elastic, optical, and thermoelectric characteristics of newly developed Quaternary Heusler alloys (QHAs) CaRbNaZ (where Z represents Si and Ge). This was achieved using the generalized gradient approximation (GGA) and the Tran-Blaha modified Becke-Johnson (TB-mBJ) potential. For both approximations, CaRbNaSi and CaRbNaGe are found to be nonmagnetic semiconductors with band gaps varying in the range from 0.49 to 1.00 eV. The studied alloys additionally conform to the Slater-Pauling rule, exhibiting a specific magnetic moment of Mtot = 8 − Ztot for nonmagnetic behavior and, therefore, having a total magnetic of 0.00 µB. They possess an optical band gap comparable to the electronic band gap, along with significant absorption properties (90 × 104 and 103 × 104 cm−1 ) in visible and UV regions, respectively, proving that these compounds are promising materials for photovoltaic cells and UV radiation shields. The high merit factor values (0.76 and 0.80) at 300K confirm that CaRbNaZ (Z= Si and Ge) are suitable candidates for thermoelectric devices.
Synthesis and characterizaton of silver/silver oxide thin film via chemical bath deposition
Authors: DANIEL THOMAS OJONUGWA , Nwankwo U.
Published: January 2025

The chemical bath deposition technique was used to deposit Ag/AgO films on a glass substrate using silver nitrate (AgNO3) and triethanolamine (a polymer matrix) as the complexing agent. X-ray diffraction (XRD) was used to study the crystalline structure of the films, scanning electron microscopy (SEM) was used to study the micrograph/morphology, and energy dispersive spectroscopy (EDS) was used for elemental composition analysis. Four peaks at 2θ values of 38.05°, 44.15°, 64.31°, and 77.41° matched the (111), (200), (220), and (311) peaks, respectively, indicating that the obtained films were crystalline. The Ag/AgO films had a relatively low transmittance value of approximately 12% in the wavelength range of 300 to 1100 nm, a band gap energy of less than 2 eV, and a high absorbance of ≥ 80%, suggesting applications in photothermal, photoelectronic devices/systems, architectural coatings, and other areas where spectrally selective films are of interest.

Published: January 2025

The effect of formaldehyde (CH2O) as a surface modifier of PbTe is evaluated. Global descriptors are calculated through density functional theory to delve into the nature of the interaction between CH2O and the PbTe surface. The CH2O molecule is structurally optimized using the PBE exchange-correlation functional and ultrasoft pseudopotentials. Subsequently, vertical ionization energies and vertical electron affinities are calculated to elucidate how the CH2O molecule behaves energetically with respect to electron removal and gain, respectively. In order to determine regions with higher and lower charge accumulation, the electrostatic potential on the van der Waals isosurface is mapped. It is inferred that the theoretical knowledge generated is useful for proposing modes of CH2O adsorption on the PbTe surface, results that rationalize the faces exposed by PbTe after surface treatment. The optimized structures of the composite systems showed a close correlation between the change in surface energy (Δγ) and the exposed faces of PbTe. Finally, through Wulff construction, the morphology of PbTe interacting with CH2O as a process control agent is determined. It was found that formaldehyde helps decrease the surface energy of the exposed faces of PbTe, leading to decahedra and faceted morphologies.
Radiation-responsive polymers: a novel spectral approach to investigate ultrahigh molecular weight polyethylene modifications using Grunwald-Letnikov and Caputo fractional order derivatives
Authors: Saeed Muhammad , Muddassar M. , Sajjad Mehmood M. , Siddiqui N.
Published: January 2025

The impact of gamma radiation on Ultrahigh Molecular Weight Polyethylene (UHMWPE) using fractional differential transformations of FTIR spectra has been probed during the current study. The gamma irradiated samples of UHMWPE for doses of 0, 25, and 50 kGy have been tested with FTIR spectroscopy, and subsequent to testing each spectrum has been analyzed with fraction order differentiation ranging from 0.5 to 1. The exhibited significant shifts in absorbance due to radiation-induced physical and chemical changes, including C=C unsaturation, C=O carbonyl absorption, and variations in CH2 bending and stretching frequencies are clearly evident even at the lowest order of applied transformation. The weak bands in spectral regions 800 − 1100 cm−1 because of gamma radiation caused peak splitting in the 800 − 1100 cm−1 region, attributed to the conversion of vinyl groups into vinylidene and trans-vinylene groups, have also been observed at all orders of applied transformations. It is, therefore, fractional differential transformations thus proved to be a potential methodology for in depth spectra analysis of radiation responsive polymers like UHMWPE with a minimal information loss during the transformation. This is also confirmed by sensitivity and specificity analysis that demonstrated that lower-order transformations are effective for accurate spectral characterization.

Published: January 2025

Rapid industrialization, households, and commerce emerging waste problems. Not only in urban societies but also in rural communities. The rural communities receive waste from their environmental condition of agro-industrial waste such as bamboo leaves. The leaves are usually dried and burned in open spaces. Former studies concluded that silica content can be found in rice husks, bamboo leaves, sugarcane bagasse, and so on by combustion process. The traditional combustion method is a simple method by which burnt bamboo leaves can produce ash with contains more carbon. This study lifted a way to produce more silica by extracting the ash using citric acid. The citric acid supports quick combustion to reduce inorganic and organic material in bamboo leaves. This process resulted in BLA in white color. The BLA substitute the cement content of concrete with composition of 0%, 7%, 8%, and 9%. The parameter in this study is to measure the density of concrete mixtures by using UPV apparatus and to measure the strength of concrete compressive by using a compression machine. The results concluded that the BLA provides a sufficient density of concrete and The BLA concrete strength has decreased with the added amount of BLA. The strength of BLA has contrasted with other studies that described improving the strength of concrete by BLA substitute from 5% to 30%. Therefore, the combustion process is still necessary to improve by taking more time for extraction and combustion process. Also, controlling slump degradation can affect water/ratio which can also affect the concrete strength.

Analytical assessment of local budgets and charges and measures to improve the mechanisms of their management
Authors: Gutsalenko L. , Dubovskiy V.
Published: January 2025

The article examines the impact of changes in the regulatory framework on local taxes and fees. The importance of local budgets in the budget system of Ukraine is outlined. Emphasis is placed on increasing the role of local taxes and fees and increasing their share in local budgets' own revenues as the main task of the state's fiscal policy. The content of Article 10 of the Tax Code of Ukraine, which sets out a list of local taxes and fees, is based on which each village, town, or city council decides on the establishment of certain local taxes and fees on its territory. The classification of local taxes (property tax, which consists of land payment, property tax other than land, transport tax, and single tax) and fees (parking fee for vehicles and tourist tax) is given. An analytical assessment of the structure of local taxes and fees of Ukraine for 2016-2018 has been made. It is emphasized that in the general structure of tax revenues of the local budgets, the role of the tourist tax is insignificant, but there is an increase of the tourist tax in Kyiv, Odessa, Lviv, and Kharkiv, which have architectural monuments, recreational infrastructure, and more. Analysis of the receipt of tourist fees to the budgets of the most popular Ukrainian resorts shows that the sole leader of the ranking is the balneological resort Truskavets. The most significant impact on local budget revenues is the tourist tax for the village. Polyanytsya (Bukovel Ski Resort), village. Koson (Kosino Thermal Resort), village. Novofedorivka (Black Sea resort Iron port) and the town. Skhidnytsia (balneological resort). It is proposed to identify additional mechanisms and measures that will help to improve the budget revenue of individual local communities, the region, and the country as a whole. Generally, timely and accurate information on local taxes and fees is necessary to analyze the performance of the enterprise, which will prevent errors in the future, allow the enterprise to optimize the tax burden, and contribute to the development of the region, since taxes paid are one of the main sources financing local budgets
Implemenation of IAS 16 “property, plant and equipment” in activity of entities of public interest
Authors: Kalyuha Ye.
Published: January 2025

Improvement of accounting and financial reporting systems is carried out in Ukraine in accordance with the requirements of international standards and legislation of the European Union. There are certain differences in the contents of AP(S) 7 "Fixed assets" and IAS 16 "Property, plant, and equipment" regarding criteria of recognition of the asset as a fixed asset; its classification, assessment, and reassessment; depreciation methods, etc. According to recognition of the asset in international practice, there is a probability that future economic benefits will come directly to the entity, and professional judgment should be applied during the determination of the unit of object in each case. Classification of fixed assets includes separate classes of vehicles (ships, planes, and cars) and tools, instruments, and implements (furniture, supplies, and office equipment). Determined types of value of fixed assets: current (recoverable), book value, and sales price. There is no residual, net realizable value of a non-current asset. Reassessment of property, plant, and equipment occurs when the residual value of an object substantially differs from its fair value. The use of the following three methods of depreciation of fixed assets is regulated: straight-line (corresponds to the straight-line method according to AP(S) 7); decrease in residual value (analogue – decrease in residual value); sums of units of production (analog of the manufacturing method). Such two methods of depreciation as cumulative and accelerated reductions in residual values are absent, but other depreciation methods are available and not limited in usage. Implementation of IAS 16 "Property, plant, and equipment" by subjects of public interest in Ukraine will allow switching into international accounting practice

The economic aspects of the production and consumption of buckwheat in Ukraine are considered. The importance of growing buckwheat and the need to develop this industry, both for achieving the main goal of agricultural producers as well as meeting the needs of the population and the successful resolution of the food problem in all regions of Ukraine and the improvement of export opportunities, are noted. The results of research on the development of this segment of the grain crops market of domestic and foreign scientists, economists-agrarians, are considered. The necessity of further scientific research on the production and provision of buckwheat products to the population was revealed. Materials for research were scientific works and periodicals of foreign and domestic economists, as well as official statistics of the Main Department of Statistics in the Kyiv region, and materials for reporting and accounting of agricultural enterprises in the region. As a result of the application of statistical, monographic methods of research, as well as the method of generalization and comparison, the analysis and research of the domestic market of buckwheat has been carried out, which reveals the main factors influencing the production, sale, and consumption of the specified products. The dynamics of the development of buckwheat production are investigated, and its economic efficiency is analyzed in the period of 2013-2017 at agricultural enterprises of the Baryshevsky district of the Kyiv region. It is noted that the agricultural enterprises of the Baryshevsky district of the Kyiv region have rather favorable geographical and economic conditions for growing buckwheat. The growth of the main economic indicators of its production, besides the level of marketability, as well as the positive and negative aspects of this process, are noted. The strategic directions of economic development of the crop sectors in agricultural enterprises of the region and Ukraine in general are noted. It is proved that the production of buckwheat is economically profitable and expedient in the present conditions. Low-cost cultivation technology, fast liquidity in the market, and high purchasing prices make it a highly profitable crop even for enterprises with little energy and resource support, which is proved by the example of agricultural enterprises under study

Published: January 2025

The market for oilseeds is especially important for Ukraine because its effective functioning is of paramount importance for ensuring the food and energy security of the state on the one hand, and the economic component on the other, because Ukraine is one of the largest players in the global vegetable oil market and is a leader in oilseed exports. Therefore, the development of the market for oilseeds requires finding ways to improve the level of supply of oil raw materials to the growing needs of processing plants every year. The development of the market for oilseeds also has a direct impact on agricultural producon and is one of the most important economic and food components of the agro-industrial complex in Ukraine. The oil and fat industry is one of the most promising and strategic ones, as it is a stable source of foreign exchange earnings for Ukraine. Therefore, Ukraine’s further participation in the world market for sunflower oil is very important. Unfortunately, the economic situation in Ukraine has adversely affected the agricultural sector of the economy. This changed the structure of products and changed the vector. The article describes the current state of the sunflower market. The main directions of its development are formulated. Problems that need to be resolved for the positive development of the sunflower market in Ukraine are identified. The recommendations and organizational and methodological approaches to the development of the sunflower market are substantiated

CE concept reverses “make, use, dispose of,” which generates a massive pile of waste in the current linear economy by creating a loop/circle as in nature [1]. Hence, a Circular Economy (CE) model would be an excellent solution to maintain the generation of construction waste [2], which is to be implemented at the earlier stages of construction projects [3]. Construction is a major buyer of resources. The individual disposal of construction materials and elements contributes highly to construction waste in Sri Lanka, e.g., timber, bricks, doors, and windows. Construction material wastage is high during construction and demolition [4]. As per the survey by [5], construction waste is generated due to activities such as discarded building materials, debris from renovations, and demolitions. Therefore, applying CE practices concerning major building materials and elements is essential to minimise waste proactively. Although many research studies have been conducted worldwide to investigate how to adopt CE principles in building materials and elements (e.g. [6], [7] ), there is a dearth of studies in the Sri Lankan context. Accordingly, this research is mounting the research problem: “How CE practices can be adopted in building materials and elements to minimise C&D waste in the Sri Lankan Construction industry?” Thus, this study aims to guide the adoption of CE practices in major building materials and elements to minimise C&D waste in Sri Lanka.

Published: January 2025

Fast suburbanization has resulted in more significant traffic backlogs demanding sophisticated traffic control solutions. This paper uses deep learning architecture to present a methodology for real-time vehicle classification and counting at intersections. Precise real-time vehicle classification and counting (RVCAC) at intersections are essential for efficient traffic management, especially in congested and heavy traffic mix conditions like those in Sri Lanka. Deep learning models deliver outstanding efficacy in object detection tasks compared to traditional machine learning models. Also, deep learning is a subcategory of machine learning. This paper explores a model that uses deep learning to classify and count vehicles around intersections. Our goal is to enhance accuracy by training a deep learning model based on a localized dataset that is specified for the Sri Lankan context. Real-time vehicle classification and counting, which are crucial for managing traffic conditions, detecting vehicle speed, identifying peak times, and more, have the potential to impact traffic management significantly.

The manufacturing industry is a fundamental pillar of the global economy. The post-industrial manufacturing paradigm considers manufacturing as a business that deals with the difficulties that companies confront in adjusting to evolving customer demands and improving productivity in the post-industrial period [1]. However, in today’s world, manufacturing is seen as a cohesive concept that encompasses everything from machines and production systems to the overall operation of a business. The global manufacturing industry is a key driver of economic growth, encompassing the production of goods across various sectors such as automotive, consumer goods, industrial products, material products, and medical devices. As illustrated in Figure 1, the industry is projected to reach a total output of US$35.1 trillion, with material products and consumer goods representing the largest segments. The industry is expected to grow at a compound annual growth rate (CAGR) of 1.10% from 2024 to 2029, driven by advancements in technology, increasing demand for consumer products, and the growing importance of industrial and material goods in global supply chains.

The current-voltage characteristics for Pt/DLC/Pt structures based on thin (40 nm) diamond-like carbon (DLC) films with Ni impurity have been studied at room temperature. The films were synthesized in the hallow Ni-cathode discharge from the mixture of argon and propane at simultaneous deposition of the DLC and Ni. The Ni concentration (10, 20 and 40 at. %) was controlled by variation of the propane portion (reactive gas) in plasma forming gas (argon) in the range of C3H8: Ar ~ 1:(1000…7000). Nonlinearity of the conductance G dependence on transverse voltage V agrees with Frenkel–Paul model: G ∝ exp(AV1/2). Observed decrease of the ln(G) - V1/2 dependence slope with increase of the Ni content was connected with increase of the DLC(Ni) dielectric permeability. Percolation threshold corresponds to Ni concentration of ~ 20 at.%.

The possibility of creating on the basis of the inverse piezoelectric effect and the negative electronic affinity of nanodiamonds (which is the natural state of the surface 111) auto-emission devices of megawatt output power operating in the key mode is considered. A comparison of two principles of operation of auto-emission devices based on a change in the field between the cathode and the anode is given. It is shown that explosive emission limits the possibility of obtaining megawatt power by changing the voltage, and also that a more promising method is to control the field by changing the cathode–anode distance from tens of nanometers to microns. Estimates are given according to which such a device has a high efficiency and can operate at a pressure of the order of atmospheric pressure.

Нафту (газ) перед подачею їх споживачам або в трубопровідну мережу їх попередньо нагрівають в шляхових нагрівачах з проміжним теплоносієм з метою зменшення в’язкості нафти або для запобігання гідратоутворення, яке виникає внаслідок зниження тиску.
У статті поставлена задача синтезу каскадно-зв’язаної системи, в якій основний канал «витрата паливного газу – температура нафти на виході нагрівача», а допоміжний «витрата паливного газу-температура димових газів.
Задача синтезу системи автоматичного керування розв’язана на основі створеної лінеаризованої математичної моделі, аналіз якої показав, що передавальна функція такої системи має дев’ятнадцятий порядок. Такий високий порядок передавальної функції унеможливлює синтез системи з використанням узагальненого квадратичного критерію. Тому з використанням методу Генкеля і методу площ отримані редуковані передавальні функції за основним і допоміжними каналами системи керування. Це дало змогу знизити порядок передавальної функції похибки керування відносно завдання основного регулятора до шостого порядку. Синтезована структура системи керування має у своєму складі ПІ-регулятор (основний контур) і П-регулятор (допоміжний контур). Задача обчислення параметрів налаштування ПІ- та П-регуляторів сформульована як задача нелінійного програмування з узагальненим квадратичним критерієм та обмеженнями, які випливають із стійкості системи керування. За допомогою програмного забезпечення розробленого в середовищі MatLab розраховані параметри налаштування ПІ- та П-резуляторів та оцінена якість процесу керування тепловим режимом шляхового нагрівника з проміжним теплоносієм.
METHODS FOR IMPLEMENTATION OF STRING OBJECT RECOGNITION RESULTS IN REAL-TIME VIDEO STREAMS
Authors: GUANXIANG Xia , KOVTUN Viacheslav
Published: January 2025

This study addresses the challenge of string object recognition in real-time video streams, particularly focusing on improving recognition accuracy under dynamic conditions with distortions such as defocusing, glare, and motion artefacts. A novel algorithm is proposed that integrates recognition results from multiple video frames using extended result models, considering alternative classification options for each object. The algorithm leverages dynamic programming and advanced metrics, such as the Generalized Levenshtein Distance, to aggregate recognition outcomes effectively. Experimental validation on the MIDV-500 dataset demonstrates the proposed method's superiority over traditional approaches, including the ROVER method, in reducing recognition errors across various text fields. The findings highlight the algorithm's robustness and scalability for applications in document digitization, automated data extraction, and mobile-based text recognition. Future research directions include optimizing computational efficiency, expanding to multilingual recognition tasks, and validating performance on diverse datasets to ensure generalizability for real-world applications.

The article systematizes and generalizes theoretical and methodological aspects of investment real estate accounting. Approaches to investment property identification are generalized. Classification features and criteria for distinguishing between operating and investment real estate are highlighted. The division of real estate into investment and operating real estate should be based not on how such real estate is used today, but on how (for what purpose) it is planned to use it in the future. To do this, the accountant must have documents such as: contracts, orders, protocols, any planning documents (business plan, financial plan, etc.) that allow to conclude on the further use of real estate. The conditions for recognizing fixed assets as investment property are defined, in particular: they are used exclusively for the purpose of receiving lease payments (only from operating lease, temporary, without transfer of ownership or lease for most of the useful life of such objects ); and / or they are used to increase equity (for example, they may be held with the prospect of rising property values and subsequent possible sales, but not for 12 months, but much longer, most likely indefinitely).
A list of generally accepted objects that are recognized as investment property has been established. The reflection of investment real estate on accounting accounts is considered. Methodological approaches to the assessment of investment real estate in accounting are systematized. Purchased or created investment property is credited to the balance sheet at its original cost. Its calculation is quite similar to the original cost of fixed assets. At the balance sheet date, investment property can be carried using one of the two methods included in the entity's accounting policy: at cost less accumulated depreciation and impairment losses on investment property and at fair value. It is proved that the accounting of investment real estate at the original (residual) value is similar to the accounting of fixed assets. Differences of reflection in the accounting of investment real estate at initial cost from fixed assets are allocated. It is emphasized that the Tax Code currently does not contain special rules for accounting for investment property.

Published: January 2025

Penulisan Artikel ini membahas pengaturan hukum terkait legalisasi arak bagi masyarakat Bali, dengan penekanan pada sejarah, budaya, dan tantangan yang dihadapi dalam implementasi Peraturan Gubernur Bali No. 1 Tahun 2020. Sejarah panjang minuman beralkohol, khususnya arak dan tuak di Bali, menunjukkan kedalaman hubungan antara minuman ini dan tradisi masyarakat lokal. Meskipun legalisasi bertujuan untuk memberikan kepastian hukum bagi para perajin, praktik penjualan dan peredaran arak sering kali masih dilakukan secara ilegal, dengan campuran yang tidak sesuai dan tanpa izin resmi. Konsumsi berlebihan minuman beralkohol juga memicu berbagai masalah sosial, seperti peningkatan angka kejahatan dan gangguan ketertiban. Dalam konteks ini, pentingnya peran pemerintah dalam pengawasan, sosialisasi, dan penegakan hukum sangat diperlukan untuk mengatur peredaran minuman beralkohol. Artikel ini juga menyoroti perlunya undang-undang khusus yang mengatur peredaran minuman beralkohol, agar ada landasan hukum yang kuat untuk melindungi masyarakat dan mencegah penyalahgunaan. Dengan demikian, penelitian ini menggarisbawahi pentingnya keseimbangan antara pelestarian budaya dan pengendalian konsumsi minuman beralkohol untuk kesejahteraan masyarakat Bali.

Exploring Educational Media on Indonesian Studies for Third-Culture Kids’ Identity Development
Authors: Hefira Vania
Published: January 2025

Indonesian Generation Z faces challenge in strengthening their national identity because of globalization. This is an urgency as Indonesia is progressing towards “Golden Indonesia 2045” where the goal is to have an advanced cultural richness over shared identity. One segmentation of Generation Z that encounters a challenge in self-identity perception is Third-Culture Kids (TCK). Their disconnection from the national identity during identity development can trigger identity crisis. One way to nurture their national identity is through teaching them Indonesian studies, consists of Indonesia’s cultural heritage, history, tradition, core values, and language. However, many TCKs struggle as they have short attention spans and language barriers towards most conventional educational media delivered in Indonesian language. This paper aims to fill in the gap of the limited research on this topic. The method is through qualitative method by reviewing previous studies on educational media related to Indonesian studies. This goal is to provide recommendations for further education development, in providing educational media for TCKs. The results underline the importance of interactivity aspects and the use of bilingual language, which has significantly helped BIPA students. The results suggest implication to design an interactive educational media that supports TCKs’ learning characteristics with local community involvement. The school managerial implication is to provide educators with inclusive education trainings and support families with transition programs during school induction.
