Authors: Prihchenko A.M. , Shatsky V.N.
Published: October 2024

The problems of designing output power amplifiers of radio transmitting systems based on the summation of the power of individual monolithic integrated circuits are considered. An analysis of well-known solutions for the construction of multichannel power summation devices in the millimeter wave range is carried out. On its basis, proposals have been developed for the construction of multi-channel summation devices with an increased level of output power. The developed devices make it possible to increase the density of amplifier cells and the level of output power while maintaining the permissible thermal regime. Individual amplifier cells can also be replaced. The developed recommendations for the construction of multi-channel millimeter-wave power summation devices can be used in the creation and improvement of output power amplifiers of radio transmitting systems.

Published: October 2024

Currently, modern networks LTE, Wi-Fi, 5GNR are combined into a single heterogeneous network, which leads to an increase in intra-system interference. According to the integrated optimization method, to distribute data flows in a heterogeneous network, taking into account the intra-system interference influence, the collective dynamic routing method is used. At the analysis stage of this method it is necessary to estimate the channel data rate in all valid routes. To obtain correct channel data rates estimates, it is necessary to reliably estimate the channel matrix. Today, the ray tracing model is widely used to estimate the channel matrix. The verification results of the using ray tracing model given in [1] show the need for additional research to increase the channel matrix estimates reliability. Therefore increasing the reliability of channel matrix transmission coefficients estimates by analyzing the influence of the number of rays taken into account is the actual task. The work analyzes the influence of the number of rays taken into account on the reliability of estimating the complex transmission coefficients of the channel matrix for the cases of the presence and absence of line of sight be-tween the transmitter and the receiver. Expressions are obtained to take into account the influence of diffracted, singly reflected and passed through an obstacle rays. A program has been developed to find all possible rays arriving at the receiver location point and determine their parameters based on a digital 3D map indicating the map objects materials. Using the developed program, it is shown that taking into account the influence of additional rays makes it possible to increase the channel matrix estimation reliability, and therefore, the modified ray tracing model can be used to estimate channel data rates when applying the collective dynamic routing method in heterogeneous net-works.

Authors: Insarov A.Yu. , Fayzullin R.R. , Il’in V.I.
Published: October 2024

The modern stage of development of telecommunication networks is characterized by active improvement of routing algorithms in packet-switched networks taking into account the provision of the required quality of service. The need to transfer large amounts of information is due to the need to ensure the normal functioning of modern multimedia applications, in particular such as IP telephony, video and radio broadcasting, interactive distance learning, which determines the multiservice nature of traffic, which is heterogeneous, and its statistical properties in most cases are of a complex polymodal nature. Taking into account the fact that traditional Poisson models providing FIFO servicing of network traffic for solving modern telecommunication problems lead to overly optimistic results in terms of delays, there is a need to develop a new mathematical model of a unidirectional switch providing FIFO servicing of multiservice traffic with polymodal distribution taking into account the provision of the required quality of subscriber service and an algorithm for estimating its main parameters. Development of a mathematical model of a unidirectional switch FIFO-service of multiservice traffic with polymodal distribution taking into account the provision of the required quality of subscriber service and an algorithm for estimating its main parameters. A new mathematical model of a unidirectional switch implementing FIFO-service of multiservice traffic with polymodal distribution has been developed, allowing one to estimate the probabilities that packets arriving at the switch input will not be processed due to overflow of its buffer memory and exceeding the maximum packet processing time. The model takes into account the delays introduced by the channel and channel equipment during the distribution and processing of packets from the source to the switch in question. Recommendations for modeling traffic processing to ensure the specified accuracy of the results are presented.

Authors: Čujan Zdeněk , Marasová Daniela
Published: October 2024

In the recent past, a rather fast growth of automated and robotised technological workplaces has been observed in various industries, including the
logistics processes which have been, until now, avoided by the automation and robotisation. One of the reasons of a currently low degree of automation in this segment is the complexity of logistics activities that relates to the manipulation with various types of objects in a rather large number of various combinations of their shapes and sizes, in most cases in a very constrained manipulation space. The output of the present article is comparative analysis of 3 different types of robots suitable for manipulation in automated warehouses using the methods of decision-making analysis. The purpose of the multiple-criteria analysis of alternative robots is to describe the objective reality in the selection carried out while applying standard procedures and formalise thus the given decisionmaking problem, i.e. transform it into a mathematical model of a multiple-criteria decision-making situation.

PROCESSOS E DECISÕES POLÍTICAS DE ENFRENTAMENTO À QUESTÃO DA HABITAÇÃO NA ESCALA DA CIDADE
Authors: Sumi Camilla Massola
Published: October 2024

O processo de dualidade da habitação no Brasil com valor de uso para sobrevivência e valor de troca como mercadoria, fez com que o próprio Estado legitimasse o "sonho da casa própria" por meio de políticas habitacionais. Isso levou ao surgimento de um vasto mercado imobiliário, em contradição, a uma parcela significativa da população vivendo em condições precárias. Neste sentido, as dinâmicas urbanas contemporâneas revelam que a moradia se tornou uma questão muitas vezes reduzida ao déficit habitacional, ignorando as desigualdades sociais estruturais. Por isso, este artigo examina as políticas habitacionais adotadas em Campinas, importante município do interior do estado de São Paulo, destacando o desafio da descentralização política e suas implicações nas desigualdades regionais e locais. Para tanto, apresenta um levantamento documental das políticas habitacionais entre pós o período de democratização ao final da pandemia de Covid-19.

Authors: Trishin Nikita
Published: October 2024

the article is devoted to the research of dependability and risk management systems at JSCo “Russian Railways” taking into account the specifics in signaling and interlocking division. On this topic the author reviews the current regulatory framework (domestic and foreign), addressing to the problems of its harmonization and proper adaptation within the company. The state of affairs in automation of dependability and risk management processes is considered, which is implemented in several corporate automated systems: “AS URRAN”, “AS ANSh”, “EKP URRAN-Sh”, “AS ANPSh”, “EK ASUI FA”, “AS FA”. A comparative analysis of these systems made it possible to determine the main directions for their improvement in order to maintain the authenticity, relevance and importance of the information contained in them. Despite many ways to model events that may lead to a violation of the transportation process safety, the article discusses one of them: the creation of the tree structure of probable events that have a sequential connection with each other. The author believes that the application of this method in practice will allow to establish typical trends in the occurrence of such cases. It will have a positive impact on the quality of predictive analytics in the company and will improve the existing risk-based approach. In addition, a rethought way to determine and visually present the level of train delays risk caused by failures in signaling and interlocking division is proposed. The central place here is occupied by heat maps of risk and its components.
The Role of External Signs of Multi-volume Editions in the Reconstruction of Kolyvan-Voskresensky Mining Plants Book Collection
Authors: Ilyushechkina T. N.
Published: October 2024

The purpose of the article is to determinate the role of the external signs in the multi-volume editions in the book marking and to solve the practical problems of reconstruction of the original composition of the book collection of Kolyvan-Voskresensky mining plants (KVMP) for the period of the XVIIIth – early XIXth centuries. This topic is considered in continuation of such issues as the reconstruction of KVMP book collection, which has already attracted the attention of our predecessors, such as formation of the fund, its cataloguing, redistribution among official Altai libraries and others. For the first time one speaks not on mechanical fixation of certain features of the copies, but on the study of these characteristics “interaction mechanisms” under the conditions of redistribution of preserved copies among different Siberian repositories. The focus is only on the signs of the early period of the existence of the book collection: stamp imprints, textual and numerical service records, specific features of bindings etc. The emphasis on early signs is due to an appeal to the earliest accounting document – “Inventory of books of Barnaul State Library, compiled by P. K. Frolov” (1809). This makes it possible to show in detail the connection between the signs on the books and the articles corresponding to these books official document and to determine the original composition of different multi-volume editions or, on the contrary avoid combining volumes that do not correspond to each other into one set. The structure of the article is determined by analysis of numerous details associated with each copy from three state repositories: State Public Scientific Technological Library of the Siberian branch of Russian Academy of Sciences, Novosibirsk State Regional Scientific Library, Research Library of Tomsk State University. The main object of the study is records of “ordinary” and “private” copy numbers, official numerical records, handwritten evidences on the inclusion of numerous drawings in book blocks as an integral part of these editions, different styles of crossing out typographical letters with ferrous ink and other signs. The features of stamp imprints are taken into account. In some cases the paramount importance of the binding characteristics is shown. The role of external signs in combining disparate copies as sets of multi-volume editions is recognized as leading. It is concluded that not just recording, but rather a thorough study of the external features of the extant sets and odd volumes of multi-volume editions is one of the basic conditions for the successful reconstruction of the book collection of KVMP.

Authors: Borisova E. I.
Published: October 2024

The article deals with current issues of theory and methodology of library and information education. Its purpose is to substantiate the expediency of forming the thematic structure of the course “Library Professionology”, based on generalization of scientific ideas about the subject of library professionology as the library science discipline. The publication analyzes the methodological approaches of specialists from the leading universities of culture (Moscow State Institute of Culture, Belarusian State University of Culture and Arts, East-Siberian State Institute of Culture) to the construction of the content of one of the special academic disciplines – “Library Professionology”, – which is included in the curriculum for training Masters of Library and Information Activity.

The author proposes one of the variants of the structural and logical model of the course “Library Professionology” – the complex theoretical and applied discipline that covers a wide range of problems related to the place and role of the library profession in the society. Mastering the essence and content of the library professionology by the Master students necessitates the acquisition of various professional competencies, with the general pedagogical competencies being the most significant among them. For this reason, the central place in the course should belong to the study of issues related to professional education – from history to current problems of organizing the library professionals training, content, methods and forms of training at the present stage.

Antibiotic-loaded bone cement has been traditionally advocated as a key step for the success of one-stage hip revision surgery, while cementless techniques have been re-cently proposed with and without the use of local antibacterials as an equally suc-cessful alternative. Aim of this review is to investigate the effective role of local anti-microbial protection for one-stage cemented and cementless hip revision surgery. Twelve studies reporting the results of cemented single-stage procedure at a minimum two years follow-up were reviewed. When pooling together the data, no infection re-currence was observed on average in 83.3% of the patients (range 75.0% to 100%). Only two papers, both from the same French group, included patients treated without the use of antibiotic-loaded bone cement, with an average infection control of 95.9% in a total of 195 patients. This figure appears better that the 80.7% infection control ob-tained by pooling together all the remaining studies. Concerning cementless one-stage revision, a total of 17 studies, reporting on 521 patients, showed an average 90.0% (range 56.8% to 100%) no infection recurrence, at a minimum two years follow-up. Eight papers reported the outcomes of cementless implants without any local antibac-terial protection and nine more described four different techniques for local antimi-crobial implant protection. No comparative study investigated cementless revision with or without local antibacterial protection. Pooled data showed an average infection control of 86.7%, without the application of local antibacterials, compared to 90.1% to 100% with local antimicrobial protection, depending on the technology used. Howev-er, due to the relatively low number of patients treated with each local antimicrobial protection, no statistical difference could be found, either considering local antibacte-rial strategies alone or pooled together. No side effect had been reported by any local antibacterial technique. This review points out that local antibacterial protection for one-stage hip revision surgery, although safe and largely performed in the clinical set-ting, appears still to rely mainly on experts’ opinion and on observational series with no prospective or comparative trial, hence no definitive conclusion can be drawn con-cerning its effective role in one-stage hip revision surgery.

Copper, along with gold, was among the first metals that humans employed. Thus, copper pol-lution of the world's water resources is escalating, posing a significant threat to human health and aquatic ecosystems. It is crucial to develop a detection technology that is both low-cost and fea-sible, as well as ultra-selective and sensitive. This study explores the use of the NH2-Xxx-His motif-derived peptide from phage display technology for ultra-selective Cu2+ detection. Various Cu-binding M13 phage clones were isolated, and their affinity and cross-reactivity for different metal ions were determined. A detailed analysis of the amino acid sequence of the unique Cu-binding peptides was employed. For the development of an optical chemosensor, a peptide with an NH2-Xxx-His motif was selected. The dansyl group was incorporated during solid phase peptide synthesis, and fluorescence detection assays were employed. The efficacy of the Cu2+-binding peptide was verified through spectroscopic measurements. In summary, we de-veloped a highly selective and sensitive fluorescent chemosensor for Cu2+ detection based on a peptide sequence from phage display library that carries the N-terminal Xxx-His motif.

Emotional competencies are a set of strategies to identify, comprehend, express and regulate emotions. They are particularly relevant in the educational context. In spite of their important, low emotional competencies have been reported in secondary students. This scoping review aims to synthesize the impact of emotional education programs on secondary students. The PRISMA Scoping method was used by using the Web Of Science, Scopus and Scielo databases. 23 studies were identified, out of which five articles were selected as they met the determined inclusion criteria. The main findings reveal significant improvement of emotional and social skills following school interventions. Specifically, progress was observed in areas such as emotional awareness, emotional regulation, interpersonal skills and emotional knowledge. The results highlight the efficacy of social-emotional learning programs in fostering social-emotional skills and psychosocial health of secondary education students. However, limitations, such as heterogeneity, were identified in the study of such research in Ibero-American countries.

Technological advancements and evolving government regulations are driving the adoption of construction equipment powered by renewable energy sources, aiming to significantly reduce emissions. Electrifying non-road mobile machinery (NRMM), particularly self-propelled Rough-Terrain Variable Reach Trucks (RTVRT) with telescopic booms, presents stability challenges. Replacing diesel engines with electric motors and battery packs shifts the centre of gravity, necessitating precise load capacity determinations via load charts to ensure safe operation. This paper introduces a virtual model developed using multi-physic modelling with Bond Graph methodology. The model encompasses crucial components, including the chassis, rear axle, telescopic boom, attachment fork, and wheels, requiring three-dimensional treatment for spatial dynamics resolution. An illustrative example, supported by experimental data, demonstrates the model's capabilities. Special focus is placed on calculating ground wheel reaction forces and hydraulic self-leveling of the attachment fork. Numerical results validate the BG-3D simulation model of the telehandler with 20-Sim as a promising tool for estimating stability limits with satisfactory precision and predicting dynamic behavior across various operating conditions. Moreover, the paper explores potential extensions of the model, such as integrating the virtual vehicle model with a platform of variable inclination in subsequent phases which aims to evaluate telehandler longitudinal and lateral stability, aligning with the ISO 22915 standard and operator safety.

Next-generation sequencing(NGS) for HIV drug resistance(DR) testing has an increasing number of applications for detection of Low-abundance drug resistant variants(LA-DRVs) as its features of quasispecies. However there is less information on detection performance in DR detection with NGS.To determine the feasibility of NGS technology in LA-DRVs detection for HIV-1 pre-treated patients.In this study,80 pre-treated patients’ samples accepted both NGS and Sanger sequencing(SS) in HIV-1 drug resistance testing. The results show that NGS presents higher sensitivity in mutation sites discovery at 5% threshold. NGS shows a satisfactory consistency comparing with SS in both protease inhibitors(PIs) and Integrase inhibitor(INSTIs), more than 90%. But worse consistency in Nucleotide reverse transcriptase inhibitors(NRTIs), only ranging from 61.25%-87.50%. The consistency of Non-nucleotide reverse transcriptase inhibitors(NNRTIs) between NGS and SS was around 85%. NGS shows the highest sensitivity of 91.3% at 5% threshold. The application of NGS technology in HIV-1 genotype resistance detection in different populations infected with HIV needs more documents and to be confirm further.
