From Data to Decisions: Leveraging AI for Proactive Education Strategies
Authors: Willie Moore  , Li-Shiang Tsay
Published: December 2024

The advancement of Artificial Intelligence (AI) and Large Language Models (LLMs) ushers in a new era in education, characterized by more adaptive, personalized learning experiences. This literature review examines the profound impact of these technologies on student engagement, achievement, and personalized learning within higher education institutions. Through a systematic analysis of scholarly articles from 2022 to 2024, this review explores how AI is reshaping educational practices through enhanced feedback mechanisms, predictive analytics, and innovative teaching methodologies. The findings indicate that AI significantly improves student support services by enabling early identification of at-risk students and by facilitating tailored educational interventions. Moreover, the deployment of chatbots and LLMs, such as GPT (generative pre-trained transformer) and BERT (bidirectional encoder representations from transformers), offers promising enhancements in instructional strategies and student assessments, fostering richer, interactive learning environments. However, the integration of these technologies also introduces ethical challenges, necessitating consideration of issues such as data privacy and bias. The review emphasizes the need for ethical frameworks and responsible AI usage to ensure technology enhances educational outcomes without compromising fairness or integrity. Future research directions are suggested, focusing on broader AI applications across various educational settings and the need for longitudinal studies to assess the long-term effects of AI integration in education.
Towards the Virtual - AI Beauty Pageants and Their Implications for Society
Authors: Knapik Ida
Published: December 2024

The dynamic growth of Artificial Intelligence is accelerating rapidly, making AI present in almost every aspect of human life. Digital assistants available on smartphones, smart homes, autonomous cars, and even recently launched AI beauty pageants. The very first Miss AI pageant, announced by the World AI Creator Awards (WAICA) program and Fanvue company, marks a new era in beauty contests. The main idea of Miss AI is to present an AI-based character, which is evaluated based on its beauty, poise, and response to typical beauty pageant questions. What makes it innovative is that Artificial Intelligence not only participates but also serves as a judge. This is because the jury, in addition to normal humans, includes virtual influencers, like Spanish digital mouse Aitana Lopez. Beauty contests have always been controversial - after all, they involve judging individuals by their appearance and setting beauty standards. However, including Artificial Intelligence in this phenomenon raises even more profound ethical questions and blurs the boundary between the virtual world and the real world. This article focuses on researching how the idea of Miss AI impacts its audience, who primarily belong to a social media-driven society. The author used content analysis and case study methods to examine the topic. Drawing on the example of one of the most popular virtual influencers, Aitana Lopez, and her increasing popularity on social media, especially on Instagram, the author reflects on the ethical implications of the Miss AI concept and its ongoing perception by society. Due to the continuous growth of AI beauty pageants, the article provides initial insights into the topic and suggests potential future developments. What can be said for certain is that recent years have brought a significant AI revolution that affects and will continue to affect a growing number of dimensions of human existence. However, this raises many concerns, increasingly centered around ethics.
Generative AI and the End of Education
Authors: Stockman
Published: December 2024

This paper reviews the prevalent rise of generative artificial intelligence and its impact on HE in the UK. In doing so, it echoes a central thought from Neil Postman's provocatively named book which reflects on the nature and purposes of education. Whilst GenAI may be approached with a constructivist disposition, much of the response in practice and policy is marked by technological determinism. A constructivist approach, however, allows us to (re)consider the nature and value of education. The paper therefore maintains the angle of the educator in asking: what are we trying to do in (higher) education? What is the purpose of Higher Education today? This is a cross-disciplinary question, much like Postman’s propositions were a cross-curricular reflection on the nature of schooling. Postman looked for a unifying narrative that can inspire ‘the ends of education’, or what education actually is and tries to accomplish, before considering its tools and approaches towards those goals. Those ends ensure that education does not become subjected to the false gods, such as economic utility and consumerism. These would spell the demise of any meaningful education, or ‘the end of education’.  What appears foundational to these questions is a belief in the nature of human potential. In education, the cultivation of that potential is arguably a fundamental end, whichever way education is organised. Where the cultivation of that potential leads, however, can remain rooted in a humanist framework, it could become posthumanist, or it could be simply bewildering. With the means of generative AI, the analysis raises questions on epistemic threat versus intellectual success, and new horizons of creative possibility in human-computer interaction. The human potentiality of thinking, interpreting, criticality, and scepticism, come forward as retained elements of the humanist narrative. In the dawn of generative AI as a teaching, learning, and assessment instrument, the end of education remains human potential. Higher Education especially, remains the place to critically and ethically stimulate the human mind towards new horizons of knowing.
Artificial Intelligence and Neural Style Transfer in the Context of Art and Design: Ethical and Anticipated Ethical Issues
Authors: Wilson Richard , Hong Eunice
Published: December 2024

From the shape of our cellphones, the colorful packaging on our foods, to the material in our clothing, every object around us typically has some kind of element of design associated with it. Design is concerned with how users interact with the objects around them. This analysis will be concerned with identifying how AI is being applied in three main categories of design: functional design, visceral design, and behavioral design. Functional designs prioritize the function of objects over form. Visceral designs are concerned with issues of the pure aesthetics of objects. Behavioral designs influence users to act based upon the design of an object, whether it pertains to purchasing the item or using the item in a preferred way. In this analysis, an overlap of these categories will be analyzed through the lens of traditional paintings. A painting reflects a story told by an artist which allows for a variety of interpretations by the perceivers of the artwork. However, what happens when Artificial Intelligence (AI) is used in conjunction with painting? AI when applied to painting uses art-related generative algorithms, and neural networks, which are adapted from models for processing data. AI relies on this type of model to complete in the case of painting, the use of a Neural Style Transfer (NST) to compose a new object of art while employing the style of another artist. Through the lenses of generative AI’s current application and implications related to its future use, this analysis will provide an extensive overview of the convergence of technology, art, and design. This discussion will also address potential ethical and future ethical concerns about authorship, originality, the value of AI-generated art, and the impact on traditional practices of Art and Design from the perspective of painting. As AI technology related to the creation of art continues to develop, anticipatory ethics will attempt to identify ethical issues with this continued development of generative AI in the area of art.
Artificial Intelligence in Banking : The Evidence from Poland
Authors: Klimontowicz Monika
Published: December 2024

The widespread use of new technologies has reduced the precise boundary between physical and digital realities. Dynamic development of artificial intelligence (AI) systems has contributed to the digital transformation of the global economy. Given its extensive range of potential applications, AI has the potential to impact a multitude of socio-economic domains, including politics, security, health care, medicine, economy, trade, finance, taxes, and production. As the banking sector plays a crucial role in the global economy, the question arises as to whether and to what extent banking market entities are willing to use artificial intelligence solutions in their business processes. This study aims to determine the scope of AI use by key banks operating in the Polish banking market. Achieving this goal requires determining what categories of AI are used by key banks operating in Poland, analysing AI methods used by those banks, and the fields of AI implementation. The research scope covers the analysis of AI applications in the largest banks operating in Poland, which together cover almost half of the market share (PKO Bank Polski S.A., Bank Pekao S.A., Santander Bank Polska S.A., mBank S.A. and ING Bank Śląski S.A). To obtain an up-to-date overview of AI usage, the research period is 2019-2024. The empirical part of the research is supported by an analysis of the widespread use of artificial intelligence and its dynamic international development based on academic papers and industry reports.
The 4I Model of Benefits and Its Integration with the Technology Acceptance Model (TAM): Teenagers’ Perspectives on Using ChatGPT for Homework
Authors: Adelhardt Zinaida , Eberle Thomas
Published: December 2024

The introduction of ChatGPT has provided students with a tool similar to a fairy-tale djinn, giving the ability to simplify homework and projects with just a few keystrokes. This study examines teenagers' perspectives on using ChatGPT for homework, exploring both the perceived benefits and concerns. Based on content analysis of responses from 141 teenagers aged 14 to 16 from grammar schools across various federal regions in Germany, we introduce the 4I Model of Benefits, identifying four key advantages: Information, Inspiration, Improvement, and Immediacy. Integrated within the Technology Acceptance Model (TAM) framework, this model clarifies factors influencing teenagers’ acceptance of AI text generators in education. Findings indicate that, while most teenagers recognize the distinct benefits of using ChatGPT, concerns about learning efficacy and over-reliance underscore the need for balanced educational integration. By enriching the TAM framework, the 4I Model identifies the specific benefits of ChatGPT that drive its acceptance and provides valuable insights for educators, policymakers, and developers.
How Good Is GPT’s “Emojinal Intelligence”? Investigating Emoji Patterns in LLM-Generated Social Media Text
Authors: Michael Dunn  , Kenneth Hopkinson
Published: December 2024

Recent advancement in Large Language Models (LLMs) has opened the prospect of generating text for social media content that mimics human writing. The misuse of these tools presents urgent dilemmas, motivating the need to better understand the structure and patterns of LLM-generated content. Human communication on the Internet has developed relevant linguistic adaptations, including the use of emoji to augment traditional text. This study investigates the ability of one LLM, OpenAI’s GPT-3.5, to replicate human emoji usage in social media contexts. Drawing upon a dataset of nearly three thousand US English human-written tweets, we employed GPT-3.5-Turbo to generate social-media-style content and analyzed the use of emoji in the resulting text. We compared the patterns of emoji usage between the LLM-generated and the human-written datasets, particularly frequency, types of emoji commonly used, and emoji sequences (n-grams). Our results revealed notable differences in all categories. While human-written tweets were more likely to use faces, hearts, and repetitive sequences of emoji, LLM-created content had a broader variety of emoji, with a preference for literal representations of the text’s subject matter, producing diverse and unique emoji combinations.
Translation and the climate crisis: Attending to the local in a global emergency
Authors: Susam-Saraeva Şebnem
Published: December 2024

Discourse on the climate crisis is intrinsically dependent on and intertwined with the concept of translation. The term is used in distinct but interrelated senses in the relevant literature. The first, reflected in the term “knowledge translation”, generally refers to the dissemination of research findings to stakeholders and the general population. The second, closely related sense of translation concerns the rendering of scientific knowledge into effective action rather than merely disseminating it. These two interrelated meanings account for the bulk of references to translation in climate crisis discourse. Finally, reference is also made in climate crisis discourse to the more familiar but less acknowledged understanding of translation as rendering research papers, children’s literature addressing eco-anxiety, and other written material into different languages, as well as interpreting in international climate summits. This contribution analyzes these different uses of the concept of translation in climate crisis discourse and discusses their implications. The analysis is supported by examples from scholarly texts and news media, and the aim is to shed light on the workings of climate crisis discourse through the lens of translation. I argue that a renewed focus on the local through a foregrounding of interlingual translation—the least explored sense of translation in this literature—may help address some of the issues currently faced by scientists and policy makers.A synopsis of this article can be found here.
Hierarchical vs. horizontal political translation in post-15M Spain
Authors: Fernández Fruela
Published: December 2024

The political and cultural atmosphere that emerged in Spain after the 15M movement was decisively shaped by translation practices, as evident in the high number of translations released by politically committed publishers, the visibility and status of translated intellectuals—such as Silvia Federici and David Harvey—, and the adoption of political concepts such as comunes and cuidados that have been shaped through complex processes of translation. Translation has also been used as a political concept by left-wing activists and political representatives, notably Podemos and other political groups. In this context, this article distinguishes between acts of hierarchical and horizontal political translation. Both proceed from a similar point of departure: the language of mainstream politics and the language of the majority of society are so profoundly disconnected that any meaningful interaction between them has to rely on practices of translation. Each of these practices involves a very different conception of politics, particularly at an epistemological level: while hierarchical translation deploys a more refined version of the traditional model of expertise, horizontal translation seems to favor a more egalitarian understanding of knowledge.

Modern trends in the formation of fallow land arrays as a prerequisite for the complication of fire situations in the Volga-Ural region
Authors: Pavleichik Vladimir , Svyatoha Natalya , Sivohip Zhanna
Published: December 2024

Wildfires pose a threat to the environment, the economy and the safety of the population in various regions of the world. In relation to steppe regions, the most important indicators for understanding the causes of fire situations are indicators reflecting the structure and dynamics of agricultural land use. The main purpose of the study was to identify regional features of the formation of fallow land arrays, taking into account the zonal structure of landscapes. The Trans-Volga-Ural region was adopted as the research area, which representatively covers a number of zonal landscapes from mixed and broad-leaved forests to southern deserts, and corresponding environmental management systems. On the basis of geoinformation products (global datasets on arable land dynamics from the GLAD laboratory of the University of Maryland and types of soil and vegetation cover (LCCS) of the FAO) and official statistical data, current trends in the dynamics of arable land use have been identified. Spatial heterogeneity in the sustainability of agricultural development is revealed due to the diversity of the natural resource potential of the region. The main areas of distribution of fallow land masses are concentrated along the southern border of the agricultural belt of Northern Eurasia, their formation is due to a number of reasons, the main of which are: a) the development of unsuitable lands in the 1950s and 1960s during the virgin lands campaign; b) negative phenomena in the economy and economy of the post-Soviet countries; c) unfavorable agro-climatic conditions of the 1990s with a subsequent tendency to increase the anomaly of the regional climate. The time period under consideration covers the period of a sharp and widespread decline in agriculture (1990–2000) and the current stage with multidirectional dynamics. Restoration of vegetation of fallow lands to a pyrogenic hazardous state takes about 10–15 years, and thus, by the early 2000s, these unused lands began to be exposed to increasing pyrogenic effects. The results obtained indicate the continued deterioration of fire conditions in areas where there is a tendency to reduce the area of cultivated land. Monitoring the transformation of land use types is an important stage in the organization of fire prevention measures and fire management.
HemipolyhedrHemipolyhedrHemipolyhedrHemipolyhedra and their Dualsa and their Dualsa and their Dualsa and their Dualsa and their Dualsa and their Dualsa and their Dualsa and their Dualsa
Authors: KIMPARA Hiroaki
Published: December 2024

There exist 9 nonconvex uniform polyhedra whose name includes “hemi”. They are called hemipolyhedra. The
duals of these hemipolyhedra share a unique feature, i.e. they are represented by a compound of prisms
interpenetrating the center of symmetry. The number of these prisms corresponds to the number of facial planes
passing through the center of symmetry of the original hemipolyhedron and the cross section of the prisms is the
same as the shape of these planes that pass through the center of symmetry. A symmetry of points and lines
arises in a projective plane: just as a pair of points determine a line, so a pair of lines determine a point. The
existence of parallel lines leads to establishing a point at infinity which represents the intersection of these
parallels. Thus, the lateral faces of the prism are considered to converge at infinity, becoming the vertices which
correspond to the original hemipolyhedron’s facial planes passing through the center of symmetry. All these are
already known and not new. However, the way to identify the vertices corresponding to the other facial planes
of the original hemipolyhedron in question has not yet been clearly established. The author gave a consideration
to this point and found a simple proper way to enable it. The purpose of this paper is to explain it in an easy-tounderstand manner.

Eğitim programları paradigmadan teoriye, teoriden de modellere uzanan kapsamlı ve birbiri ile bağlantı bir süreç sonucunda ortaya çıkmaktadırlar. Bu sebeple eğitim programlarında teorik alt yapının önemi yadsınamayacak derece büyüktür. Günümüzde programın uygulamaya dönük yüzü olarak görülen modellerin öne çıktığı ancak modellerin temelinde bulunan eğitim programı teorilerinin ulusal alanyazında yeterince ele alınmadığı görülmektedir. Bu çalışmada eğitim programı teorisinin önemine dikkat çekerek alanın öncü isimlerinden olan Ralph Winfred Tyler ve eğitim programı teorisi üzerinde durulmuştur. Çalışmanın ilk bölümünde paradigma, teori ve model arasındaki ilişkiden ve program teorilerinin sınıflandırılmasından bahsedilmiştir. Bir sonraki bölümde Ralph W. Tyler’ın hayatı, eğitime ve programa bakış açısı ve program teorisi yer almıştır. Program geliştirme modeli de ifade edildikten sonra Tyler’ın çalışmalarının geçmiş ve günümüz yansımaları tartışılmıştır. Günümüzde etkisi devam eden Tyler rasyonelinin çeşitli gelişmeler ışığında daha iyi anlaşılmasının ve tartışılmasının program teorisi alanına katkı sağlayacağı belirtilmiştir.
Una propuesta didáctica de comprensión lectora centrada en los modos de decir. Aportes para abordar las dificultades de lectura de textos disciplinares en el nivel secundario
Authors: Tosi Carolina
Published: December 2024

Es sabido que las dificultades de comprensión lectora que manifiesta el alumnado en la escuela secundaria no se limitan al plano conceptual o léxico, en los que suelen hacer hincapié los estudios más difundidos de la didáctica, sino que se vinculan sustancialmente con otros aspectos textuales, como la enunciativos, subjetivos y polifónicos. Partiendo del postulado de que las prácticas de lectura escolares pertenecen a la tradición contenidista (Hall, 2007), puesto que el objetivo que las guía es “hallar” contenidos en el texto, esto es, descubrir qué dicen los textos y no en desentrañar cómo lo dicen (Hall, 2007), el presente artículo se propone abordar la comprensión lectora haciendo foco en la materialidad discursiva de los discursos disciplinares, explorando, por un lado, las formas que construyen los sentidos y, por el otro, los recursos específicos que configuran la subjetividad y la polifonía. Sobre la base de los resultados de una encuesta exploratoria realizada a docentes de escuelas secundarias de la Ciudad y provincia de Buenos Aires (Argentina) durante 2023, y desde el marco de la polifonía y la enunciación (Ducrot, [1984] 2001; Authier-Revuz, 1984 y 1995; Maingueneau, 1999 y García Negroni, 2005 y 2008), se retoma, se problematiza y se expande la noción de “estrategias de facilitamiento”, que busca motivar la reflexión lingüística respecto de los textos pedagógicos en pos de fomentar la alfabetización académica (Tosi, 2015a, 2017 y 2018). En esta oportunidad, se plantea el diseño de una propuesta pedagógica centrada en los modos de decir de la comunicación científica para la comprensión de la lectura de textos de estudio disciplinares en el entorno. A lo largo del trabajo, se muestra la relevancia de una propuesta de este tipo, cuya pretensión consiste en promover la reflexión metalingüística y la desnaturalización de formulaciones discursivas cristalizadas en los procesos de comprensión lectora de las diferentes disciplinas del nivel medio, cimentando, así, un trabajo transversal que pueda ser puesto en juego en las diversas áreas del conocimiento.
COMPARATIVE EFFECTIVENESS OF MIXED-LANGUAGE AND FULL ENGLISH
CONVERSATION CLUBS ON VOCABULARY DEVELOPMENT AMONG INTERMEDIATE ENGLISH LEARNERS IN UZBEKISTAN
Authors: USMONOVA Matkhiya
Published: December 2024

This study explores the impact of Mixed-Language and Full English Conversation Clubs on vocabulary development among pre-IELTS learners in Uzbekistan. Using a mixed-methods design, the research involved 16 students, divided into two groups, who participated in four 90-minute sessions focused on IELTS-related vocabulary. The Mixed-Language Conversation Club, which initially allowed native language support before transitioning to English, showed significant and consistent improvements in vocabulary acquisition compared to the Full English Conversation Club, which used English exclusively from the start. Quantitative data from pre- and post-tests and Likert scale surveys supported by qualitative insights from interviews revealed higher engagement and efficiency for intermediate learners in the Mixed-Language approach. The findings suggest that integrating native language support in the early stages of language learning can enhance vocabulary development and overall language progress.

Obesity in Southeast Asia: An Emerging Health Concern
Authors: MR Alam , M Begum , R Sharmin , AZM Naser , MM Rahman , MA Hossain , SKM Tanveer , MM Parves , E Ahmed , T Akter
Published: December 2024

Background: Obesity is a growing global health concern, with developing countries such as Bangladesh increasingly facing the dual burden of undernutrition and overnutrition. The rise in obesity in Bangladesh, particularly in urban areas, is closely linked to rapid urbanization, economic development, and lifestyle changes, leading to increased consumption of processed, calorie-dense foods and reduced physical activity. This literature review examines the prevalence, drivers, health implications, and policy responses to obesity in Bangladesh within the broader context of global and Southeast Asian trends. Objective: The objective of this review is to analyze the rising concern of obesity in Bangladesh, explore its health and socioeconomic implications, and assess the effectiveness of current interventions and policy responses. The review also highlights gaps in the literature and suggests future research directions for addressing obesity more effectively in both urban and rural populations. Methods: A comprehensive review of open-access, English-language literature published between 2000 and 2024 was conducted using databases such as Google Scholar, PubMed, and CrossRef. The inclusion criteria focused on studies examining obesity prevalence, risk factors, health implications, and interventions in Bangladesh and Southeast Asia. Results: The review identifies a significant rise in obesity rates in Bangladesh, particularly in urban areas, where rates have reached 24% among adults. The key drivers of obesity include rapid urbanization, dietary shifts toward processed foods, and sedentary lifestyles. The health implications of obesity are severe, with strong associations to Type 2 diabetes, hypertension, and cardiovascular diseases. Policy responses remain limited, and community-level interventions have had mixed success due to underfunding and lack of coordination. Conclusion: Obesity in Bangladesh reflects broader global and regional patterns while presenting unique ..
sacristías parroquiales del valle del Salado.El singular programa iconográfico e iconológico de las pinturas de la sacristía de la Magdalena (Santamera, Guadalajara)
Authors: Jiménez Balbuena Cristina
Published: December 2024

El desarrollo de los espacios auxiliares en las iglesias de la comarca del Salado, obispado de Sigüenza, parece responder a priori al modelo de sacristía dispuesto en Trento. Sin embargo, una primera aproximación a sus tipos y el análisis de la iconografía de las pinturas murales de la Magdalena de Santamera (Guadalajara), muestra que algunas de sacristías, más allá de ser espacios donde custodiar el ajuar sagrado, fueron concebidas por las instituciones eclesiásticas como lugares de adoctrinamiento y evidencia de la desconfianza que debían tener hacia los cristianos nuevos.

This paper introduces a synthesis of an algorithm for estimating the parameters of a communication channel based on the observed M-QAM signal with a known information sequence. The proposed algorithm leverages the method of moments, expressed in the form of the Tikhonov A.N. functional, which allows for the efficient estimation of various channel parameters. These parameters include the amplitude, phase, and frequency shift of the received signal. The phase noise is also incorporated into the phase model to provide a more accurate reflection of real-world channel conditions. The estimation process was carried out under conditions of additive white Gaussian noise (AWGN), as well as in scenarios where the noise followed a lognormal probability distribution. The phase was assumed to follow a uniform distribution. To evaluate the performance of the proposed algorithm, a computational experiment was conducted, focusing on the accuracy of parameter estimation for a 64-QAM signal. The results obtained using this method were compared with those achieved through advanced Kalman filtering, a well-known approach for parameter estimation in communication systems. Additionally, a rough analysis of the computational complexity of the algorithms was performed, comparing the method of moments to recursive nonlinear filtering algorithms. Experimental curves depicting the interference immunity of 64-QAM signal reception were obtained using both the synthesized algorithm and the advanced Kalman filtering method. These results provide valuable insights into the effectiveness and practical feasibility of the proposed approach for parameter estimation in communication channels, particularly in noisy environments. To further validate the robustness of the proposed algorithm, different noise levels and channel conditions were tested in the simulations. This allowed for a comprehensive assessment of the algorithm's adaptability and accuracy under varying signal-to-noise ratios (SNR), ensuring its applicability across a wide range of practical communication scenarios.

Published: December 2024

The subject of the study is technological interruptions during repair work on railway transport. Technological "windows" represent an interval in the movement of trains on one of the tracks during double-track traffic and have different durations, depending on the planned repair and the number of track machines involved in its implementation. The purpose of the study is to assess the possibilities of obtaining optimal indicators of the operational performance of a railway line during technological breaks of various durations for the implementation of repair work on the stretch. The presented scientific research was carried out using mathematical methods for assessing the optimal duration of a technological break by correlating the parameters of financial costs and the values of quantitative and qualitative indicators of the operation of railway transport. The approaches used make it possible to obtain graphs of the dependence of the number of required technological windows on the time of their implementation, which includes the number of locomotives used, the duration of the limiting operation, and the duration of operation of track machines. The obtained analytical relationships can be considered the main results of the research. The capabilities of the applied approach can be used in drawing up a directive schedule for planning technological breaks on the railway network to generate optimal values of operational indicators, taking into account the creation of a database for the implementation of planned indicators based on an analysis of the factors influencing them. The presented results of numerical modeling make it possible to estimate the duration of technological breaks, taking into account the time to bring track machines into working condition, which forms the planned need for breaks in the movement of trains, affecting the reduction of planned values of operational indicators.

Published: December 2024

The paper presents the development of a new tool in fraction-of-time approach, where a random process is described by means of functional models synthesized based on its singe realization, without the need to construct abstract probabilistic models as reliable a priori information on the process ergodicity property is lacking. Based on the analytical formula, expressing the fraction-of-time density of a continuous signal in explicit form, a method for estimating the fraction-of-time density of a digital signal was proposed. A piecewise continuous linear function was chosen as an approximating model used to restore a continuous-time signal from its samples. The first-order interpolating model made it possible to develop a light-weight digital signal processing algorithm that forms an analytical expression for the estimated fraction-of-time density of the observed signal. It is shown that the expression consists of two parts: a regular part rep resented by the sum of rectangle pulses, and a singular part represented by the sum of Dirac deltas. The simulation results are present ed for three cases, including a periodic signal, a stationary random process with its known correlation function, and a second-order cyclostationary process. For the most complex case of a cyclostationary process, the proposed algorithm demonstrated a gain in estimating the probability density compared to the known method of kernel probability density estimation with a Gaussian smoothing function chosen. As an expected direction of practical application of the method and algorithm based on it developed within the framework of the conducted study, an improvement in the quality of solving data analysis problems for which the accuracy of probability density estimates is of significant importance is supposed, for example, problems of detecting random signals with unknown parameters.

Published: December 2024

Results of researches of the electromagnetic properties of oil substances in the microwave frequency band are presented in this work. Possibilities of using microwave heating in oil industry and pumping of oil products are considered. The possibility of using microwave heating to solve a number of problems of oil production and pumping oil through pipelines is being researched. Using waves in the microwave range allows in many cases to concentrate the heat release in the most viscous paraffin and bitumen components, which as a result reduces the viscosity of these components. To determine optimal wave frequencies and powers used for heating, it is necessary to know the electromagnetic characteristics of oil-containing mixtures. Experimental researches consisted in measuring the attenuation of electromagnetic waves passing through a "clean" section of the waveguide and through the same section of the waveguide after passing petroleum products of various compositions through it. The additional attenuation of oil pollutions in the frequency band 9-11 GHz does not exceed 0.27 dB/m. To determine the electromagnetic properties of oil-containing materials in the microwave band, experimental researches were conducted on the coaxial segment, which is filled with the researching substance. Losses in conductors are dominated by losses in contact connections. The wave penetration depth in the substance decreases with an increase in frequency, which must be taken into account in the heating technology. Parameters of researching substances were calculated, and their frequency dependences are presented. The losses in oil deposits significantly exceed losses in pure oil, therefore these deposits will heat up more, than pure oil. This effect can be used to reduce the viscosity of oil both in oil pipelines during oil transportation and in the production of high viscosity oil. It is possible to determine the required heating power and time to use microwave heating technology for the oil industry.

The article deals with the problem of registering the signal radio profile of an electronic device when powered from an alternating volt age source with a high parasitic impedance. A method for recording a signal radio profile is proposed by examining the voltage drop on a low-resistance shunt connected in series to the power supply circuit of the electronic device under study. As a result of the simulation, the best switching time for the power supply of an electronic device was obtained. Compensations for the internal inductance of the power supply have been developed, which increases the correlation relationship of signal radio profiles obtained at various internal inductances. The scope of the inductance compensation method, its advantages and limitations are indicated. A parametric com parison of the switching elements connecting the power supply to the electronic device under study has been carried out. A method for switching on a relay with compensation for the contact group switching delay time is proposed, and the switching delay time for a relay based on a mercury reed switch is given. To verify the parameters of the signal radio profile obtained from various power sources, an experiment was conducted that showed the correctness of the simulation and the operability of the method of compensation for the inductance of the power supply. Based on the values of the instantaneous voltages of the signal radio profiles obtained as a result of the experiment, their correlation analysis was carried out. For the first time, high values of the correlation coefficient between signal radio profiles from a reference DC power supply and from an AC power supply with internal impedance compensation were obtained. Conclusions are drawn about the possibility of using a low-resistance shunt in the power supply circuit to obtain a signal radio profile, and about the correctness of the proposed method of compensation for the internal inductance of the power supply. The result of the study can be used in the field of technical diagnostics of electronic devices operating from both AC and DC networks with high parasitic impedance.
Cellular Internet of Things Modeling: The Literature Review
Authors:   Moscow Technical University of Communications and Informatics, Tammam Dawood
Published: December 2024

This article presents a literature review on the Cellular Internet of Things (CIoT) and outlines how mathematical modeling can be used in the development of efficient solutions to model, analyze, and design CIoT networks. CIoT, by its nature, connects enormous device counts in cellular networks, thus facing challenges associated with scalability, latency, energy consumption, and security. Mathematical models, including Markov chains, queuing theory, and stochastic models, are considered important in simulating network behavior and predicting performance under varying conditions. Accordingly, different models are categorized with respect to their approaches and which specific aspects of CIoT they tackle. It is found that there is no comprehensive hybrid study in the previous literature that includes resource allocation and performance evaluation in burst access cases of mobile IoT devices with different traffic natures. Most previous studies focus on resource allocation in IoT networks, but they often ignore various QoS require ments, such as latency, for example. The review shows important direc tions, challenges, and gaps in recent research, pointing toward the necessity for more evolved and up-to-date models reflecting contem porary CIoT network complexities. This study would be a useful and efficient approach for researchers and designers of various CIoT mod els to assess the current state of CIoT modeling in the literature and identify future work opportunities as well.
