Trusted outdoor multi-camera tracking system powered by FPGA

Computer vision has become a crucial area of research due to the increasing use of electronics, information technology, and network communication. Adding more algorithms to the process of locating text, faces, vehicles, and other moving objects can improve the effectiveness of the search when compared to a "ground truth" reference. This work aims to track a moving object as it passes through the fields of view of multiple outdoor cameras. Both the temporal difference algorithm and the fixed background algorithm have been used in the search process for objects in a video with a frame dimension of 120 by 160 pixels. The FPGA panel used in the system was the Xilinx Spartan-6 LX45T. This method can speed up the overall process because it does not require the objects to be registered first. The proposed approach is highly resistant to object orientation and robust, with an error rate of less than (0.05), resulting in the best possible results in terms of global recognition. Consequently, it attains exceptional global recognition results while maintaining its reliable performance.

The specifics of public authorities' communications in social networks on the example of using the remote electronic voting system in the presidential elections of the Russian Federation in 2024

The subject of the study is the communicative process arising in the digital space in the context of the use of remote electronic voting (hereinafter referred to as DEG) in the presidential elections of the Russian Federation in 2024. The purpose of the work is to develop practical recommendations for improving the communicative interaction of the state and society in social networks. The authors analyze new forms of interaction between government agencies and the public, as well as conflict situations arising in this regard. Particular attention is paid to the perception of the DEG system by citizens, the identification of factors causing negative reactions, such as technical failures and insufficient information support from government agencies. The author also discusses the issues of mediatization of political processes in the context of digitalization and information warfare. In addition, the author examines the tactics of government agencies' reaction to negative comments and fakes. Statistical methods of analysis of official publications and comments, as well as elements of sentimental and critical discourse analysis were used for the study. The scientific novelty of the work lies in the study of public communications related to the introduction of DEG, as an example of the mediatization of political processes in Russia. The study identifies key factors that provoke conflict situations in the process of using the DEG system, such as technical failures and insufficient level of advice on solving these problems. Conclusions are drawn about the need to improve feedback from the public, increase information transparency of the system and develop more effective solutions for technical support. Measures to reduce conflict in communications through the use of mediation technologies and strengthening dialogue between government agencies and society are also proposed. In addition, this work emphasizes the need for further research and improvement of mediatized interaction processes.

RIS-aided free-space optics communications in A2G networks over inverted Gamma–Gamma turbulent channels

Reconfigurable intelligent surfaces (RISs) have revolutionized free-space optics (FSO) communication by dynamically optimizing the propagation environment. This study proposes a framework to analyze RIS-assisted FSO communication over inverted Gamma–Gamma (IGGG) distributions. We use the IGGG distribution for air-to-ground networks, accurately modeling atmospheric turbulence. Consequently, we derived performance metrics in terms of Meijer’s G by employing an asymptotic analysis to provide deeper insights. Our results demonstrate incorporating RISs into our proposed network enhances outage performance by 52.08% at a SNR of 30 dB. Furthermore, the results highlight the importance of heterodyne detection in mitigating the adverse effects of pointing errors.

Fixed-Time Congestion Control for a Class of Uncertain Multi-Bottleneck TCP/AWM Networks

As network technology continues to advance, network congestion has become an inevitable aspect of network communication. Considering the external interference, unmodeled uncertainty and the interaction between nodes, a multi-bottleneck TCP/AWM network model is established in this paper. A new fixed-time congestion controller was designed by combining a neural network and the backstepping technique. The neural network approximation property is used to eliminate the interference of unmodeled uncertainty and UDP flow in the system. The controller designed in this paper can ensure the stability of the TCP/AWM closed-loop system in a fixed time. Finally, the simulation results demonstrate the effectiveness of the proposed TCP/AWM controller.

End-to-End Resource Allocation Management Model in Next-Generation Network: Survey

Network communication has grown rapidly with massive demands of services. Moreover, resource allocation in networking is a fundamental and crucial issue that cannot ensure the network's stability and efficiency with the myriad requirements of different services. Various vertical businesses may seek varied network services, particularly in the Fifth-Generation networks and Beyond (5G+). The pros of Fifth-Generation communication networks are to outperform 4G in performance by having higher bandwidth, minimum latency, more capacity, and QoS (Quality of Service). Software-Defined Network (SDN) and Network Function Virtualization (NFV) are two technologies that are combined in the next generation cellular network to provide improved network management. The primary idea behind resource allocation (RA) in the next generation network is the concept of network slicing where the network resources are virtually partitioning into many separate networks. Each separated network must satisfy the unique needs of the required service to achieve the required QoS. In this survey, we focus on resource management issues related to network slicing and tackling the biggest obstacles in this field while offering a thorough and up-to-date overview of this field. Thus, thorough analysis of the allocation of resources on the access side and core side of the network communication was sought. Also, demonstrates how revolutionary techniques that are used to support the management of sliced networks which are based on Machine Learning (ML) and Artificial Intelligence (AI). Importantly, use appropriate ML techniques such as deep learning for predicting the network condition and Reinforcement learning to learn optimal allocation policy without depending on prior knowledge and other techniques such as classification and clustering to aggregate the similar needs of users into separate slices. This could help to enhance resource utilization by allocating a sufficient amount of resource as needed based on ML algorithms and optimal utilization of resources and reducing operational costs by real-time adjustment of it based on user demands and network conditions

Achieving Reliability of Privacy-preserving Phantom Routing Protocols in Multi-hop Wireless Sensor Networks

Due to the open nature of wireless channels and sensor node resource constraints, it is challenging to secure the communication in wireless sensor networks (WSNs) while simultaneously protecting the privacy of node location data. Therefore, a significant amount of research focusing on source location privacy (SLP) protocols has been conducted. The amount of research on SLP reliability, meanwhile, is insignificant. This study explores the operational features of various privacy-preserving phantom routing protocols and simulates WSNs with varied network configurations to investigate how different routing strategies affect SLP reliability. Safety period and capture ratio metrics are used to compute SLP reliability. Simulation results show that integration of phantom routing with fake packet distribution mechanisms adversely impacts SLP reliability. SLP reliability decreases also as the number of fake packet sources increases. Research proves that a protocol with many fake packet sources achieves SLP reliability for a mission duration of 940 rounds, while a protocol with no fake packet sources achieves SLP reliability for 1658 rounds.

Коммуникация студенческой молодежи с органами местного самоуправления в социальных медиа

Digital technologies, including in the field of communication between government bodies and the population, are actively used in the context of achieving the goal of digital transformation. Young people use social networks in their everyday lives as forms, mechanisms, technologies of self-realization, self-expression, selfsearching and simply life. Students are one of the most active groups of young people who not only master professional competencies in the learning process, but also get involved in the socio-political agenda of their city, region, country. How familiar, understandable and natural is it for them to interact with local government bodies in social networks? The scientific problem of the study is the lack of empirically substantiated information on the attitude of students to the potential of digital communication with local public authorities in social networks. The authors use the Mix research strategy. The accounts of municipal administrations of the Sverdlovsk region (N=73), as well as the accounts of heads of municipalities (N=71) in the social network VK were analyzed using parsing tools. The data are supplemented by the results of qualitative in-depth interviews with student youth (N=26). The analysis showed that young people do not consider social networks as a channel for dialogue and two-way communication with local governments due to low awareness of the existence of municipal administration accounts in social networks, lack of understanding of how to build a dialogue through this channel and low trust in this communication channel as effective, lack of examples of constructive solutions to issues through social networks. At the same time, the involvement of young people in communication in social networks is higher in the personal accounts of heads of municipalities, but, at the same time, there are fewer young people subscribed to such accounts. To build a dialogue with municipal authorities through social networks, it is necessary to demonstrate to youth the possibilities of communication with municipal administrations in social networks in the context of not only openness and transparency of power, but also involvement in the development and adoption of management decisions.

Dynamic event‐triggered model‐free adaptive control for networked control systems with random packet loss

AbstractA novel dual‐channel dynamic event‐triggered model‐free adaptive control method with compensation is proposed for nonlinear networked control systems (NCSs) subjected to random packet loss. In order to tackle the issue of redundant data transmission, a dual‐channel triggering control framework is designed, where data transmission only occurs upon meeting the triggering conditions. Compared with the traditional static event‐triggered schemes with fixed triggering thresholds, the proposed method allows for dynamically adjustable triggering thresholds. This means that the number of data transmissions in the forward and feedback channels can be further reduced. In addition, considering the detrimental impact of random packet loss and output event‐triggered on the system, compensation is applied to the system's output data using the linear data model of the nonlinear system, which is directly derived from I/O data without incorporating any other mechanistic model information, thereby ensuring optimal control performance. In contrast to existing results, the proposed control strategy can enhance system performance while conserving network communication resources. The effectiveness and superiority of the proposed scheme have been validated through two simulations.

Variability of the harmonization narrative of network communication in media discourse

This study aims to analyze the variability of the harmonization narrative produced in the process of interaction in new media (social networks, blogosphere, etc.). The empirical material for the study was based on the original posts and comments selected using a stratified sampling method from two frontier regions: North Ossetia-Alania and Dagestan. To achieve this aim, the main trends in the implementation of tactics for harmonizing online communication were identified, which made it possible to determine the main ways of resolving the conflict in the Internet space of the frontier regions. These tactics were analyzed in their connection with the thematic and interpretative vectors in which they are implemented. This further allowed us to reveal the variability of the narrative under consideration. The study is based on discourse, modus, statistic and linguistic analysis. Harmonization tactics were considered in the paradigm of direct dependence of positive communication formation and the promotion of Russian ideas in virtual space. As a result, it is determined that the narrative basis of harmonization is the promotion of Russian civilizational constants, their positive representation and identification with socially significant events. Further analysis of the connection between communication tactics and semantic directions confirms this trend, while demonstrating a high variability of themes (North Ossetia-Alania - 17; Dagestan - 26). All this leads to the functioning of harmonization as a single narrative principle that unites many themes. It is expressed as a complex system surrounding socio-political ideologemes that mark a single civilizational path and are capable of uniting multicultural, multi-ethnic and multi-confessional stratified communities, neutralizing possible conflicts between them. At the same time, the implementation of this narrative is quite variable and includes many themes and sub-themes, differentiated depending on the value systems common in a particular region.
