Published: July 2021

Рассмотрены проблемы оптимизации распределенной структуры атмосферной лазерной коммуникационной сети. Поставлена и решена задача оптимизации распределенной атмосферной оптической коммуникационной сети, содержащей один передающий и n приемных узлов. Определено выражение оптимальной связи между дивергенцией луча на входах приемных узлов и расстоянием между передатчиком и этими узлами, при реализации которой суммарное затухание в системе при условии неизменности других факторов, способствующих ослаблению сигнала, достигает минимума.

The problems of optimization of the distributed structure of atmospheric laser communication network are considered. The problem of optimization of distributed atmospheric optical communication network containing one transmitting and n receiving nodes is formulated and solved. The formula determining the relation between beam divergence at the input of receiving points and the distance between these points and transmitter is obtained. Technical implementation of this formula brings to a minimum of total attenuation in the system, provided that other factors potentially causing signal attenuation are unchanged.

Любая модель должна быть адекватной и конструктивной, т.е. обеспечивать эффективное и целенаправленное использование, в том числе для анализа критичности к изменению параметров моделируемой системы. Применяемые во многих компаниях при маркетинговых расчетах громоздкие и негибкие финансовые Excel-построения не позволяют инвестору оперативно принимать решения об экономической целесообразности проекта. Предлагается алгоритм, упрощающий эту задачу применительно к облачным радиомодулям RAN.

Any model must be adequate and constructive, i.e. ensure its efficient and purposeful use, including for the analysis of criticality to changes in the parameters of the simulated system. The cumbersome and inflexible financial Excel constructions used in many companies in marketing calculations do not allow the investor to make quickly decisions about the economic feasibility of the project. An algorithm that simplifies this task in relation to cloud RAN radio modules is proposed.

Рассмотрены существующие и ожидаемые к появлению в ближайшем будущем сценарии несанкционированных воздействий (НВ) на системы связи в критических информационных структурах. Показано, что область повышенного риска НВ сосредоточена на интерфейсах между периферийными устройствами и чипом SoC. Приведены примеры организации в группы множеств абонентских терминалов, действующих под единой программой НВ, в которых уровень проникновения может многократно повышаться. Отмечается, что такие возможности реальны при переходе к системам поколения 5G, предполагающим режим работы M2M.

Some existing and expected in the near future scenarios of unauthorized impacts on communication systems in critical information structures are considered. It is demonstrated that the area of increased risk of unauthorized impacts is focused on the interfaces between the peripheral devices and the SoC chip. Several examples of organizing multiple subscriber terminals into groups operating under a single program of unauthorized influence, in which the level of penetration can increase many times, are given. It is noted that such opportunities are real in the transition to 5G generation systems, which assume the M2M mode of operation.

Authors: АВЕРЬЯНОВ Р.С.
Published: July 2021

Рассмотрен режим хэндовера системы МАКВИЛ, предназначенный для устранения конфликтов распределения ресурсов радиоканала и ориентированный на пространственную селекцию радиосигналов абонентов соседних базовых станций (БС), осуществляемую 8-элементными адаптивными антенными решетками (ААР). Представлен алгоритм управления ААР БС, направленный на ликвидацию конфликтов при максимальных нагрузках. Приведено описание алгоритма пространственной селекции, ориентированного на условия возможного отсутствия трасс прямой видимости и, как следствие, произвольных законов амплитудно-фазовых распределений полей на антеннах. Установлена численная связь между энергетическим запасом на краях зон обслуживания и эквивалентным угловым расстоянием между абонентами, достаточным для бесконфликтного пространственного разделения одинаковых спектрально-временных ресурсов. Показано, что ввод управляемого параметра задержки в режиме синхронизации позволит реализовать в МАКВИЛ пространственное разделение абонентов, обслуживаемых одной БС.

The McWiLL system handover mode, designed to eliminate conflicts in the distribution of radio channel resources, focused on the spatial selection of radio signals of subscribers of neighboring base stations, carried out by 8-element adaptive antenna arrays, is considered. An algorithm for controlling the adaptive antenna arrays of base stations, focused on eliminating conflicts at maximum loads, is described. The description of the spatial selection algorithm, focused on conditions of the possible absence of line-of-sight traces and, as a result, arbitrary laws of the amplitude-phase distributions of the fields on antennas, is given. A numerical relationship is established between the energy reserve at the edges of the service areas and the equivalent angular distance between subscribers, sufficient for conflict-free spatial separation of identical spectral-time resources. It is shown that the input of a controlled delay parameter in the synchronization mode will allow the implementation of spatial separation of subscribers served by a single base station in the McWiLL system.

Three-Dimensional Localization of Active Aerial Targets Using a Single Terrestrial Receiver Site
Authors: kaviani saber , Behnia Fereidoon
Published: July 2021

This paper proposes a method for the three-dimensional localization of an active aerial target by a single ground based sensor. The proposed method employs the time and frequency differences of arrival of the signal received directly from the aerial target and the signals received after being reflected from some large auxiliary terrestrial targets (pseudo-sensors) with known positions on the ground. Due to the terrestrial nature of the main and the pseudo sensors, it is impossible to solve for the target's altitude using traditional methods. The proposed method employs target motion analysis to obtain target position including its altitude with acceptable accuracy and low computational complexity. Presented simulations confirm acceptable accuracy of the proposed method in determining three dimensional position of the target despite limited number of the pseudo sensors and its low computational complexity.

Published: July 2021

The aim of this study is to determine the programmed cell death hallmarks in the stigmatic papillae of Brassica oleracea L. The flower development was divided in two main stages; pre-anthesis and post-anthesis. Programmed cell death hallmarks were examined in parallel to these stages. At pre-anthesis, the stigmatic papillae were ovoid and their dense cytoplasm were rich in insoluble polysaccharide and protein. At post-anthesis, vacuolization and enlargement were quite evident in papillae. Besides, the protein content decreased, but reactive oxygen species increased in comparison to the pre-anthesis stage. Although no significant change in superoxide dismutase activity was detected, catalase activity decreased and hydrogen peroxide content increased at post-anthesis. DAPI stained nuclei appeared rounded and smooth appearance at pre-anthesis, however, some invaginations and fragmentation in nuclei were observed at post-anthesis. Although, TUNEL staining was negative at pre-anthesis, while TUNEL positive reaction was significant in the nuclei of papillae at post-anthesis. In comparison to the pre-anthesis, the number of fragmented nuclei monitored by DAPI and TUNEL staining increased at post-anthesis.

Authors: Fallah Fahimeh , Ghahremaninejad Farrokh
Published: July 2021

Genome size is a helpful tool for circumscribing taxa at diverse taxonomic degrees (mostly species) and resolving intricate low-level taxonomies. The correct genome size in Hedera (Araliaceae) has long been discussed, and the ploidy levels of some taxa are still unclear. Twelve accessions of Hedera were measured via flow cytometry. Flow cytometry is a relatively rapid, inexpensive, and credible tool. Fresh leaves of Hedera samples and internal reference standard parsley (Petroselinum crispum) were stained with propidium iodide (PI). Flow cytometry measurements showed that for the accessions of 2CV (3.09 - 6.40 pg), the lowest amount of nuclear DNA was 3.09 pg for Hedera crebrescens (So), while the highest amount was 6.40 pg for H. hibernica “Hamilton,” representing a statistically significant difference. According to this study, the new taxon (H. crebrescens) is a diploid, though this taxon was previously considered H. hibernica (tetraploid).

Published: July 2021

In the current study, it is aimed to investigate the toxic effects of a widely used herbicide Roundup containing active ingredient glyphosate on cucumber (Cucumis sativus) by cytological and molecular investigation. Three different concentrations (0.6%, 1.2% and 2.4%) of Roundup were applied to cucumber for 48 and 72 hours. At the end of the application procedure, the germination percentage, mean root length, mitotic frequency and mitotic abnormalities, RAPD profiles and Genomic template stability (GTS) were determined in root apical meristematic cells. For RAPD PCR analysis 10 RAPD primers were used, 8 of them produced band patterns and it was found that 5 RAPD primers among them produced unique polymorphic band patterns and subsequently were used to produce a total of 24 bands. Observed percentage of polymorphism was 26%. The changes in RAPD profiles after Roundup treatment was included variations as gain and/or loss of bands compared with the control group. Genomic template stability changed in RAPD profiles at various Roundup concentrations.

Statement of the problem. The scheme of a statically definable girder of a spatial rectangular surfacing is discussed. The problem is to identify the formula for the dependence of the lower estimate of the first frequency of the natural oscillations of the structure by means of the Donkerley method on the number of panels. The truss has supports on the sides and consists of separate rod cells connected in pyramids. Results. Based on the analysis of the sequence of analytical solutions for the first frequency of girders with a different number of panels by induction, the coefficients in the desired formula are derived. The common members of the sequences of coefficients are found as solutions of homogeneous recurrent equations formed according to the results of the calculations using Maple operators. The resulting dependences are obtained in the form of polynomials by the number of panels. A comparison of the analytical solution with the numerical one is provided.Conclusions. An algorithm for deriving an analytical estimate of the fundamental frequency of oscillations of a spatial structure depending on the number of panels, mass, size, and elastic properties of the material is shown. The spectrum of oscillation frequencies of the structure is analyzed. The resulting dependences can be employed in seismic and structural optimization problems.

O presente artigo tem como finalidade realizar um estudo da correlação de dados referentes às taxas registradas de incidência da dengue nos municípios que fazem parte da Gerência Regional de Saúde de Leopoldina com variáveis socioeconômicas. Realizou-se a correlação de Pearson com as 232 variáveis contidas no Atlas do Desenvolvimento Humano no Brasil para identificar quais possuíam maior correlação com a Taxa de Incidência de dengue nos municípios analisados. No desenvolvimento dos mapas dos municípios, utilizou-se o software ArcGis versão 10.8 e para obter e estudar o nível de correlação (r) entre as variáveis, utilizou-se o software Minitab versão 19. Foram identificadas quatro variáveis relacionadas ao ensino de nível básico e uma ao esgotamento sanitário com maior correlação de Pearson dentre as demais. Para apresentação dos resultados, foi criado um gráfico de Pareto com as 25 correlações mais fortes e identificou-se que as primeiras 10 variáveis representaram um total de 50% das causas do problema, porém, utilizaram-se as 5 primeiras para realização do artigo, que foram mostradas em uma tabela, com as respectivas correlações (r) e seu nível de significância (p). Pode-se concluir que se faz necessário que as Secretarias de Saúde dos municípios realizem mobilizações nas escolas de forma rotineira e forneçam materiais para que os professores possam abordar o tema com maior frequência com os alunos. Além disso, se mostrou necessário o acompanhamento de agentes de saúde em residências que se encontram em situação de precariedade no abastecimento de água e saneamento básico afim de orientar sobre os riscos e como se prevenir.

Authors: Shehata Ahmed Maher Khafaga , Hassan Amr Hassan Fatouh
Published: July 2021

The purpose of this paper is to report the findings of a study of information-seeking behavior among a group of Arab postgraduate students in social science and humanities disciplines. The paper also explores information-seeking styles and examines how information seeking is affected by external factors. The study employed a qualitative approach to explore informationseeking behavior in the sample and the sources of information used to obtain scholarly information. A sample of 33 participants was interviewed to elucidate the information-seeking behavior of the Arabic language speakers. The analysis of the interviews revealed that the participants use different methods to find information on the internet. These methods vary from using search engines to using sites that provide pirated scholarly papers. The data showed that most of the sample students use search engines and databases provided by their universities, but they should be trained in research ethics to avoid unacceptable research practices. The results also indicate that searching in other languages represents a challenge for Arab postgraduates in the social sciences and humanities. This study was conducted with social science and humanities postgraduates as part of a series of studies aiming to explore Arab language speakers' scholarly practices. The information-seeking behavior of science disciplines may differ, as the teaching language is mainly in English. This study contributes to the field by expanding our understanding of how non-English language speakers seek scholarly information and what sources are used to obtain the scholarly papers.
Dynamic Programming in Data Driven Model Predictive Control?
Authors: Jianhong Wang
Published: July 2021

In this short note, one data driven model predictive control is studied to design the optimal control sequence. The idea of data driven means the actual output value in cost function for model predictive control is identi_ed through input-output observed data in case of unknown but bounded noise and martingale di_erence sequence. After substituting the identi_ed actual output in cost function, the total cost function in model predictive control is reformulated as the other standard form, so that dynamic programming can be applied directly. As dynamic programming is only used in optimization theory, so to extend its advantage in control theory, dynamic programming algorithm is proposed to construct the optimal control sequence. Furthermore, stability analysis for data drive model predictive control is also given based on dynamic programming strategy. Generally, the goal of this short note is to bridge the dynamic programming, system identi_cation and model predictive control. Finally, one simulation example is used to prove the e_ciency of our proposed theory

Este artículo exhibe un panorama de las escrituras críticas que el sistema académico argentino elaboró sobre las relaciones entre las concepciones de los márgenes sociales y el cine argentino de ficción. El impacto de la crisis económica, social e institucional que eclosionó en el 2001 generó la necesidad de preguntarse por los modos en los que el cine establecía un dialogo con la crisis. Esta pregunta inicial perduró en el campo académico hasta la actualidad. Por lo tanto, este artículo delimita una serie de ideas y percepciones que la relación entre las miradas y escrituras críticas construyeron con algunas obras a lo largo del tiempo. El artículo da lugar a los vínculos entre la estética y la precariedad, la representación de los espacios sociales urbanos signados por la pobreza material y simbólica y el surgimiento de los autores cinematográficos provenientes de los márgenes sociales.
Retrato y archivo. Desplazamientos entre lo público y lo privado
Authors: Staude Mariela
Published: July 2021

Resumen

Este trabajo propone analizar el cortometraje Babás (Consuelo Lins, 2010) a partir de dos cuestiones centrales: el uso particular del archivo y la noción de retrato (fotográfico, cinematográfico, pictórico) que se desplaza tanto de soportes como de significados. La directora parte de una fotografía encontrada en un archivo público y desde allí irá  a buscar en el suyo propio el material necesario para hacer un homenaje a las niñeras. En esta búsqueda, la visita al pasado y su relación con la memoria se torna central, por eso el concepto de archivo, desde la redefinición que señalaron Michel Foucault y Jacques Derrida, servirá para abordar y reformular la escritura, la memoria, los cuerpos y sus representaciones. Lins somete las imágenes a prueba y especulación, las escruta para que digan lo que en principio no dijeron e intenta reconstruir a través de desplazamientos (de tiempo, espacio y soporte) una ausencia.
Inscripciones precarias. Israel, la Patagonia y el presente extendido en La parte automática de Ivo Aichenbaum
Authors: Kantor Débora Galia
Published: July 2021

En el cine argentino de la última década, y específicamente dentro de las variantes del “ensayo-documental”, encontramos un corpus de películas que retratan, a través de formas y miradas críticas diversas, singulares encuentros entre sujeto, imagen y experiencia sobre el territorio israelí. “¿Qué me une con esa comunidad tan lejana y de la que me encuentro separado por el espacio y por el tiempo?”: La interrogante que signó a generaciones previas retorna y se abre nuevo camino y forma en cada film. En este artículo nos proponemos explorar una película fundante -La parte automática (2012), de Ivo Aichenbaum-, la primera de una serie todavía abierta.
La Película no es del director
Authors: Aguilera Viruéz Franklin de Matos Yanet
Published: July 2021

Se analizará la película Llucshi Caimanta, con el objetivo de discutir la problemática indígena en el cine y en los movimientos militantes históricos del subcontinente. Ejemplo contundente de cómo el pasado se imbrica en el presente, esta película nos hace sentir cómo el imperialismo extractivista interfiere de forma siniestra en nuestro destino. Estas imágenes producidas en el pasado, contemporáneas nuestras, nos hacen pensar sobre el porqué de que seamos aún vilipendiados y robados.
Deconstrucciones y críticas de las tecnologías occidentales de lo sensible
Authors: Cangi Adrián
Published: July 2021

Para comprender las tecnologías occidentales de lo sensible abordamos en este texto una deconstrucción crítica, bajo una mirada arqueológica de los discursos del “humanismo” como antropología-técnica del dominio colonial y una perspectiva genealógica del problema del “Yo” en los campos del “diseño de sí” que concentran el modo estético-sensible de las logísticas del capital.
El schock colonial. Tecnologías de lo humano y arte fronterizo
Authors: Piñeiro Aguiar Eleder , Lorenzo Castiñeiras Juan José
Published: July 2021

En este texto de carácter teórico e interpretativo desarrollamos una triangulación entre un arte político y la conceptualización decolonial en torno al racismo y al pensamiento fronterizo. Para ello analizamos las obras de varios autores que han venido trabajando la otredad y los ponemos en debate con una crítica a la modernidad capitalista eurocéntrica. Como eje vertebrador tenemos el diálogo intercultural, la práctica de viaje, los usos tecnológicos de la vigilancia y del control y las relaciones de poder hacia poblaciones subalternizadas. Lo que queremos destacar es la importancia de lo que denominamos schock colonial como configurador de propuestas “otras” para entender la línea de lo humano.
Del tercer cine al movimiento de video: teorías y prácticas descolonizadoras en el audiovisual latinoamericano
Authors: De la Fuente Alejandro , Guerrero Claudio
Published: July 2021

El presente texto aborda el espacio audiovisual latinoamericano en diferentes contextos históricos representados por dos grupos y soportes distintos, por un lado, el tercer cine en los 60 y 70 y, por el otro, el Movimiento Latinoamericano de Video en los 80 y 90. El objetivo es analizar el potencial descolonizador de las teorías y prácticas que en ellos se registraron. Para ello revisamos sus desarrollos, continuidades y proyecciones enfocándonos en el modo en que se concebía la condición colonial latinoamericana, las metodologías y estrategias que nutrían sus prácticas audiovisuales descolonizadoras y las maneras en que buscaron la autonomía en la producción, distribución y recepción del audiovisual. Finalmente, ponemos en perspectiva ambos momentos y grupos para dar cuenta de sus puntos de encuentro y tensión.
