ML-Enhanced Live Video Streaming in Offline Mobile Ad Hoc Networks: An Applied Approach

Live video streaming has become one of the main multimedia trends in networks in recent years. Providing Quality of Service (QoS) during live transmissions is challenging due to the stringent requirements for low latency and minimal interruptions. This scenario has led to a high dependence on cloud services, implying a widespread usage of Internet connections, which constrains contexts in which an Internet connection is not available. Thus, alternatives such as Mobile Ad Hoc Networks (MANETs) emerge as potential communication techniques. These networks operate autonomously with mobile devices serving as nodes, without the need for coordinating centralized components. However, these characteristics lead to challenges to live video streaming, such as dynamic node topologies or periods of disconnection. Considering these constraints, this paper investigates the application of Artificial Intelligence (AI)-based classification techniques to provide adaptive streaming in MANETs. For this, a software-driven architecture is proposed to route stream in offline MANETs, predicting the stability of individual links and compressing video frames accordingly. The proposal is implemented and assessed in a laboratory context, in which the model performance and QoS metrics are analyzed. As a result, the model is implemented in a decision forest algorithm, which provides 95.9% accuracy. Also, the obtained latency values become assumable for video streaming, manifesting a reliable response for routing and node movements.

“The A.M. Kovalev’s Conception of ‘Just Society’ in the Context of Current Political and Philosophical Discussions”

In modern political and theoretical discourse, the concept of a ‘ just society’ is usually perceived as a normative idea that expresses the notion of what society “should be”. Nowadays, social justice as a political slogan is becoming an increasingly universal requirement made by social movements, political parties and groups regarding the ways of social organization and its functions. Regardless of the different interpretations, it is inseparable from other related concepts, such as ‘equality’, ‘ freedom’ and many others. It also represents the projection of various concepts of justice on social relations in individual countries, regions, and, finally, throughout the world (‘global justice’ on the scale of all mankind). Comparative analysis of the A.M. Kovalev’s concept of a just society and the main trends in the interpretation of this idea in modern Western socio-political theory indicate that the methodology developed by an outstanding Russian scientist can rightfully be considered one of the most promising. Its distinguishing feature is the creative interpretation of a set of ideas about a just society, dating back to the early works of Marx. It is combined with the analysis of the ideas of the Western European Enlightenment, the philosophy of Kant, Hegel and Fichte, the evolution of the social philosophy of the Frankfurt School and other equally influential areas of modern political theory (R. Aron and others). An analysis of modern political theories shows that the dyad “ justice / state” constitutes the ontological core of the political and philosophical discourse, in the structure of which the ideas of Marxism play an important role. In the A.M. Kovalev’s theory of a just society, the various assessments of the heuristic potential of Marxism acquire additional incentives, opening the way to new creative discussions. The article is dedicated to the 100th anniversary of the birth of A.M. Kovalev.

Sustainable Financing for Transport Infrastructure: An Integral Approach for the Russian Federation

The development of global transport infrastructure is a crucial aspect of economic growth and prosperity. In this study, the main trends in the development of global transport infrastructure are analyzed, with a focus on the state and trends in the functioning of the national transport infrastructure of the Russian Federation. By identifying key problems and determinants of financial growth, a preliminary decomposition is made to guide future development. Proceeding from the fact that the innovative development of Russia’s transport infrastructure should occur through state stimulation of the development of intellectual and partnership relationships and the formation of a digital environment for managing projects for its innovative transformation at the state level, this study identifies the goals, methods, and levels of ensuring the implementation of innovative transformations in transport infrastructure. Consideration of the historical aspects of the formation of the modern economy and comprehension of the mechanisms of state management and tools to ensure innovative transformations in the sphere of transport allowed us to identify three stages (dogmatic, strategic regulation, and innovative integration) of transformation regarding the theory of the state management for the innovative development of transport infrastructure in Russia. Taking into account the content of these periods of transformation allowed us to detail the specifics of the modern stage; highlight the shortcomings; and propose theoretical and methodological foundations for revising the provisions of the state regulation of innovative development in transport infrastructure. To determine the effectiveness of the processes of the state regulation of innovation activity in the transport industry, we propose a model for assessing the effectiveness of innovation activity in the transport complex, which is presented in the form of a three-level parametric system, where the first group of indicators allows us to assess the innovation activity of economic entities in the transport industry; the second allows us to assess innovation potential; and the third allows us to assess the effectiveness of innovation. The novelty of the proposed model is the consideration of the principles of dynamism, perspective, and expediency, and its application allows us to establish the level of innovative development in transport infrastructure. An important factor in ensuring the sustainable development of a country’s economy and forming its positive image in the world is its financial attractiveness. Therefore, the assessment of financial attractiveness is a priority task for the development of modern sustainable transport infrastructure in Russia.

Structure of pellet cloud emission and relation with the local ablation rate

The experimental reproduction of the conditions of pellet injection expected in future large devices being not possible in present day machines, it is mandatory to validate as thoroughly as possible the available ablation models. Among the different points still under discussion, there is the relation between the spectroscopic measurement of the ablation clouds and the local ablation rate. This relation is investigated by coupling an emission model to the time-dependent simulation of ablation clouds with the HPI2 pellet ablation/deposition code. The simulated quantities are the time-evolution of the cloud visible spectrum (λ = 400–700 nm) and images in different wavelength domains (e.g. Hα,Hβ or the continuum centered at λ=576nm ). It is found that the cloud emission is anisotropic, this is particularly the case for H α and H β lines, and that the relation between the cloud emission and the ablation rate depends not only on the conditions of pellet injection, but also on the direction of observation. It follows that, in general, it is not possible to estimate the ablation profile from that of an emission line (Hα or Hβ) . The code predictions are compared with corresponding measurements for a welldocumented pellet injected in LHD, showing a good agreement for global values and main trends. The reasons for observed discrepancies are discussed.

Some criminological indicators of land mismanagement

Based on official statistical sources, this article presents a long-term criminological analysis of the situation with land mismanagement in Ukraine spanning the period from 2002 to 2023. The author determines absolute, average and relative indicators, in particular, the rate and dynamics of crimes in this category. The total number of recorded crimes in the category under study (1,240 crimes), their average annual occurrence (56 crimes), and the average growth rate (22.9 %) are calculated. Employing a 5th degree polynomial function, a trend depicting the dynamics of these crimes is constructed. The chosen model aptly captures the development trend of the process with high precision (coefficient of determination R2 = 0.916) and facilitates the identification and characterization of four distinct periods, each reflecting the main trends of land mismanagement in Ukraine.&#x0D; A paradoxical situation is revealed by the analysis of the practical application of the criminal law provisions which have supplemented Art. 254 of the Ukrainian Criminal Code « Land Mismanagement» in accordance with Law of Ukraine No. 402-IX of December 19, 2019 « On Amendments to Certain Legislative Acts of Ukraine Regarding Improvement of Legislation on Mining of Amber and Other Minerals». Notably, no crimes were recorded under Part 2 of Article 254 of the Criminal Code of Ukraine (the primary corpus delicti). Conversely, 15 crimes were recorded under Parts 3 and 4 of Article 254 (qualifying elements of the crime). The author concludes that this correlation would be impossible in the case of objective recording of crimes, and it also underscores a noteworthy latent aspect of land mismanagement, in particular, deliberate evasion of mandatory reclamation of lands damaged in the course of pilot commercial development of amber deposits or amber mining under a special subsoil use permit, resulting in considerable damage. The conducted analysis holds an intrinsic value both for scientific research and for law enforcement, ensuring an appropriate information support base for countering land mismanagement, firstly, by providing a clear understanding of the current situation with this phenomenon. Furthermore, it lays the groundwork for the development of the relevant system of criminal preventive measures tailored to address this specific issue.

A Review of Document Binarization: Main Techniques, New Challenges, and Trends

Document image binarization is a challenging task, especially when it comes to text segmentation in degraded document images. The binarization, as a pre-processing step of Optical Character Recognition (OCR), is one of the most fundamental and commonly used segmentation methods. It separates the foreground text from the background of the document image to facilitate subsequent image processing. In view of the different degradation degrees of document images, researchers have proposed a variety of solutions. In this paper, we have summarized some challenges and difficulties in the field of document image binarization. Approximately 60 methods documenting image binarization techniques are mentioned, including traditional algorithms and deep learning-based algorithms. Here, we evaluated the performance of 25 image binarization techniques on the H-DIBCO2016 dataset to provide some help for future research.

Numerical Study of the Thermal and Hydraulic Characteristics of Plate-Fin Heat Sinks

One of the main trends in the development of the modern electronics industry is the miniaturization of electronic devices and components. Miniature electronic devices require compact cooling systems that can dissipate large amounts of heat in a small space. Researchers are exploring ways to improve the design of the heat sink of the cooling system in such a way that it increases the heat flow while at the same time reducing the size of the heat sink. Researchers have previously proposed different designs for heat sinks with altered fin shapes, perforations, and configurations. However, this approach to optimizing the design of the heat sink results in an increase in the labor intensity of its production. Our goal is to optimize the heat sink design to reduce its size, reduce metal consumption, and increase heat flow. This goal is achieved by changing the number of fins and the distance between them. In this case, there is no significant difference in the geometry of a conventional plate-fin heat sink, and a low labor intensity of production is ensured. A numerical investigation of heat flow and pressure drop in models of plate-fin heat sinks of various sizes and metal volumes was conducted using the ANSYS Fluent software package (v. 19.2) and computational fluid dynamics employing the control volume method. We used the SST k-ω turbulence model for the calculations. The research results showed that by changing the number of fins and the distance between them, it is possible to increase the heat flow from the heat sink to 24.44%, reduce its metal consumption to 6.95%, and reduce its size to 30%. The results of this study may be useful to manufacturers of cooling systems who seek to achieve a balance between the compactness of the heat sink and its ability to remove large amounts of heat.
