Authors: Игнатова Т. А. 
Published: May 2022

Раскрыта сущность процесса формирования здорового образа жизни в студенческой среде. Сформирована структура мотивов, побуждающих студентов заниматься физической культурой и спортом и проведена апробация результатов исследований на конкретном примере в соответствии с данной структурой. Сегодня одной из основных стратегических задач образования является воспитание молодежи в духе ответственного отношения к собственному здоровью и здоровью окружающих, как к высшей индивидуальной и общественной ценности. Проблематика укрепления здоровья все чаще признается одной из приоритетных отраслей научного знания, и по своей практической значимости и актуальности является одной из сложнейших проблем современных наук: медицины, психологии, педагогики. В последнее время особую актуальность приобретает проблема студенческого здоровья. Современная молодежь живет и развивается в эпоху социально-экономических и политических перемен, кризисных условий ХХI века, что способствует росту асоциальных явлений среди студентов, таких как наркомания, курение, алкоголизм, что разрушающе влияет на здоровье. В связи с этим, проблема здоровья студентов является приоритетной проблемой современности, где актуализируются вопросы укрепления здоровья, здорового образа жизни, формирования у студентов мотивации к укреплению здоровья.
The essence of the process of forming a healthy lifestyle in the student environment is revealed. The structure of motives encouraging students to engage in physical culture and sports has been formed and the results of research have been tested on a concrete example in accordance with this structure. Today, one of the main strategic objectives of education is to educate young people in the spirit of a responsible attitude to their own health and the health of others, as the highest individual and social value. The problem of health promotion is increasingly recognized as one of the priority branches of scientific knowledge, and in its practical significance and relevance is one of the most complex problems of modern sciences: medicine, psychology, pedagogy. Recently, the problem of student health has become particularly relevant. Modern youth lives and develops in the era of socio-economic and political changes, crisis conditions of the XXI century, which contributes to the growth of antisocial phenomena among students, such as drug addiction, smoking, alcoholism, which has a devastating effect on health. In this regard, the problem of students' health is a priority problem of our time, where the issues of health promotion, healthy lifestyle, formation of students' motivation for health promotion are actualized.

Представлена компьютерная реализация алгоритмов, предназначенных для численного моделирования трехмерных выпуклых тел со случайным числом вершин. Построение выпуклых многогранников является классической проблемой вычислительной геометрии. Интерес к таким моделям возникает в целом ряде задач физики, биологии, медицины. В данной работе модели построения выпуклых тел ориентированы на приложения, связанные с решением задач расчета характеристик рассеяния оптического излучения ледяными кристаллами перистых облаков. Алгоритмы построения выпуклых многогранников были положены в основу программы ConvexHull, предназначенной для моделирования кристаллов произвольных выпуклых форм в трехмерном пространстве. В работе описаны алгоритмы построения и результаты визуализации с помощью библиотеки OpenGL.
Cirrus clouds consist of ice crystals of various shapes, sizes, and orientations. In the numerical study of the radiation characteristics of cirrus clouds, simplified crystal forms likes regular polyhedra (for example, prisms with hexagonal bases) are often used. To study the optical properties of irregularly shaped ice crystals, a number of authors of the previously constructed models in which, for example, a part of the crystal is cut off by a random plane, or the angle between some crystal faces changes randomly. In this paper, it is proposed to use the convex hull of randomly generated or user-specified points in three-dimensional space as a model for irregularly shaped ice crystals. A method for modeling three-dimensional convex polyhedra with a random arrangement of vertices is presented, which is based on the incremental and the directed edges algorithms. Each face of the modeled convex polyhedron is triangular. By stretching and squeezing, as well as an appropriate choice of the distribution function of random points in space, the resulting polyhedra can simulate the irregular shapes of ice cloud crystals. As a result of the algorithm execution, the number of vertices, their coordinates are saved, and for each face of the polyhedron, the sequence of vertices is ordered to make their vector product corresponds to the right-hand rule and determines the direction of the outer normal. These models of three-dimensional convex bodies of various sizes and irregular shapes are designed to calculate the attenuation coefficients and the scattering phase functions of optical radiation by cloud crystals using the ray tracing method. The paper presents a visualization of crystals modeled according to the given algorithm, and the dependence of the number of vertices and faces of the polyhedron on the number of generated random points. The program code is written in C++ using the OpenGL library.

Рассмотрена возможность обнаружения лесного подроста с помощью поляриметрических разложений и анализа временны´х рядов радиолокационных изображений ALOS-2 PALSAR-2 и Sentinel-1. Представленные результаты показывают принципиальную возможность уверенно определять рост лесных насаждений.
The problem of large-scale assessment of forest restoration after artificial deforestation and wildfires is relevant in connection with climate change and the corresponding desire of the world community for further low-carbon development. One of the promising methods aimed at solving this problem is remote sensing of the Earth using space-based synthetic aperture radars (SAR). The paper proposes a comprehensive approach to assessing the dynamics of forest plantings growth using time series analysis of ALOS-2 PALSAR-2 and Sentinel-1 radars data, as well as Sentinel-2A/B optical sensors data. It is shown that with the help of model-based decomposition (Freeman-Durden decomposition) of fully polarimetric data in L-band (ALOS-2 PALSAR-2), the increasing of volume scattering component and the corresponding decrease in the surface component can confidently identify the growth of young forest. However, the data of ALOS-2 PALSAR-2 with dual polarization are not able to separate forest undergrowth from other types of vegetation over a seven-year observation interval. This is also true for the C-band. Thus, the polarimetric Cloud- Pottier decomposition of Sentinel-1 data allowing only separation for the areas with vegetation from the treeless ones. Time series analysis of radiometrically corrected radar backscattering at vertical co-polarization in this band, imaged in the winter period of time, allows reliable determining of the dynamics for the growth of forest plantations. The use of freely available Sentinel-2A/B multispectral sensors data makes it possible to further divide the identified undergrowth by species composition and exclude classification errors of radar data in treeless areas, which show an increasing of volume backscattering component on model-based polarimetric decompositions.
La complexité herméneutique à l’épreuve du calcul
Authors: BACHIMONT Bruno 
Published: May 2022

Les textes offrent la possibilité de manipulations calcultoires via leur matérialité sémiotique : les symboles informatiques codant les caractères permettent la mobilisation d’algorithmes et outils informatiques. Cependant, ces traitements butent sur ce que nous appelons la duplicité du sémiotique, selon laquelle les symboles informatiques ne sont pas des signes dans la mesure où les premiers ne signifient rien contrairement aux seconds : les calculs sont effectués indépendamment de l’interprétation des signes textuels. Manipulation computationnelle et interprétation herméneutique sont donc hétérogènes et distincts, la première ne peut qu’approximer et simuler la seconde. Cet écart procède de la nature du sens et de ce qui manque aux machines pour y accéder. Cet article considère les différents types de complexité, analytique, synthétique et herméneutique pour voir dans la dernière ce qui résiste à réduction calculatoire. Ce constat est approfondi en revenant à la constitution phénoménologique du sens et ce qui fait que le sens d’un texte n’est accessible qu’à une entité ayant la notion d’un environnement qui l’excède et d’un ailleurs qui lui manque. Cet écart irréductible ne disqualifie pas l’intérêt des traitements algorithmiques : ils permettent bien au contraire de s’émanciper des contraintes du sens. Mais les résultats doivent être finalement repris et réassumés dans une entreprise herméneutique, pour transformer les données résultats en textes à comprendre.
Le traitement du potentiel argumentatif des mots en analyse du discours
Authors: GALATANU Olga 
Published: May 2022

Dans la perspective théorique de la Sémantique des Possibles Argumentatifs, l’article s’interroge sur la nature sémantique et le statut épistémologique des observables dans la matérialité du texte, tels qu’ils sont proposés par son traitement informatique : mots, associations de mots, environnements sémantique et syntaxique. La thèse défendue est que l’analyse de ces observables n’épuise pas le sens discursif et qu’elle doit s’appuyer sur une démarche de prise en compte dans l’interprétation du sens non seulement du contexte, mais aussi et surtout de la complexité du potentiel argumentatif des mots. Le corollaire de ce point de vue est une triangulation des méthodologies dans laquelle l’analyse qualitative sémantico-discursive des conceptualisations sémantiques offre un modèle conceptuel au traitement textométrique qu’elle précède.
Pourquoi les actes de langage politiques échappent-ils au traitement linguistique des données ?
Authors: ANQUETIL Sophie 
Published: May 2022

La présente recherche tend à montrer que la propension d’un acte de langage à devenir fait institutionnel et ainsi à « se faire politique » tient à sa « force illocutoire complexe » et à la construction d’un implicite institutionnel (Anquetil, à paraître). En prenant appui sur l’exemple d’ALERTER, nous déterminerons comment le processus d’institutionnalisation en trois phases – 1. l’assignation d’une fonction agentive aux faits institutionnels ; 2 la construction d’une croyance et intentionnalité collectives ; 3. la construction d’une éthique politique – influe sur le marquage de l’acte de langage et fragilise la possibilité d’en saisir les données à l’aide d’outils de fouille textuelle.
Républigram fever
Authors: SIMON Justine 
Published: May 2022

L’article analyse les spécificités de la culture du partage en contexte numérique à partir d’une illustration récente. Il s’agit de l’expérience Républigram née en réaction à la communication politique d’Emmanuel Macron sur le respect des gestes barrières en février 2021. Le graphiste Martin Le Hénand a créé un « Générateur de photos Présidentielles » qui permet aisément de détourner les images initiales. Puis ce dernier a invité la communauté Twitter à partager sa création. À partir de l’analyse d’un corpus de tweets, l’enjeu est de saisir la relation réciproque établie entre technologies numériques et culture participative. Cette étude met en relief plusieurs caractéristiques essentielles de la culture du partage en régime numérique : l’expérience sociale de communautés virtuelles, la visibilité sociale (et l’invisibilité sociale), la participation au débat public, les imaginaires sémiodiscursifs, la présentation de soi et l’engagement émotionnel.
Il n’y a pas d’alternative : les imaginaires de l’innovation dans les discours d’Emmanuel Macron
Authors: DEFILIPPI Fabrizio 
Published: May 2022

Cet article explore les imaginaires sociaux autour de la technologie, en analysant les discours du président français Emmanuel Macron ayant pour thème l’innovation. L’objectif est de comprendre quelle place occupent l’innovation et la technologie dans l’imaginaire macronien. Nous montrons que les discours étudiés (période 2017-2021) sont traversés par une dimension de « nécessité » : l’innovation y est présentée comme un élément incontournable pour résoudre des problèmes de nature diverse. L’évocation de scénarios indésirables devient l’occasion pour réaffirmer la nécessité d’une accélération de l’innovation. En prônant une adaptation de la société à un certain modèle d’innovation, ces discours semblent renouveler le slogan thatchérien « TINA – there is no alternative ».

PDC Media Group is a company engaged in online trading. The need for data insight in the online marketplace is very important. Likewise, how to get quite a lot of data, of course, requires automation such as crawling data on the marketplace website. Due to the large amount of data, crawler systems are often not optimal in crawling data. The application of distributed tasks on the crawler system provides convenience in scaling the server both vertically and horizontally. Therefore, the large and growing data can be handled by the crawler system. The application was developed with the Python language, with the application server using Google Cloud Computing. In a distributed task architecture requires a component in the form of a message broker. The message broker used in designing this system is RabbitMQ. Testing the crawler system uses 3 scenarios, namely with 1 worker, 2worker, and 3 worker. The results for the 1 worker scenario are 19.3 requests per second and 332 ms for response time. The results for the 2 worker scenario are 41.4 requests per second and 328 ms for response time. While the results for the 3 worker scenario are 60 requests per second and 331 ms for response time.
Site Effects Study in the Peshawar District using Seismic Noise

Published: May 2022

Surficial geology plays an important role during earthquakes in terms of its impact on the resulting ground shaking, referred to as site effects. Site effects influence the level of earthquake hazard and risk in a region. Peshawar, the provincial capital of Khyber Pakhtunkhwa, is one of the most seismically active cities in Pakistan. However, it lacks any such seismic characterization. In this work, a seismic ambient noise study was performed in Peshawar using observations from a total of 92 stations. The seismic noise data is recorded using a broadband seismometer for a period of about 30 minutes at every station point. The fundamental resonance frequency and a first-order amplification based on the seismic noise recording are estimated using the method of Nakamura. First-order estimates of the amplification range from 1.0 to 7.0, whereas the resonance frequency ranges between 0.2 to 2.5 Hz. The results suggest a complex geological structure with low seismic impedance and deep soil deposits in Peshawar. The depth of soil deposits is estimated to be more than 300 m, leading to a potential amplification of low-frequency seismic waves. These findings are crucial for tall structures with fundamental vibration periods greater than 0.40 sec. Doi: 10.28991/CEJ-2022-08-04-010 Full Text: PDF
Durability and Microstructure Characteristics of Concrete with Supplementary Cementitious Materials
Authors: Bramha Chari K. J. , Ranga Rao V. 
Published: May 2022

Considering the environmental impact of cement manufacturing industries, this paper concerns the potential of using supplementary cementitious materials (SCMs), like fly ash and ground granulated blast furnace slag, as being essential to replacing the existing Ordinary Portland Cement (OPC). The objective of this paper is to study the microstructural characteristics of concrete with SCMs and improve the durability of the product to increase the lifespan of concrete structures. Replacement SCMs in OPC are 0, 40, 50, and 60 by percentage of cement weight, and we have taken a water-binder ratio of 0.40 for M40 grade and 0.28 for M60 grade concrete. The physical properties and chemical composition of OPC, Ground Granulated Blast-furnace Slag (GGBS), and fly ash were identified, and three different experiments were conducted to determine the resistance to penetration of chloride ions and corrosion processes. The rapid chloride permeability test, accelerated corrosion, and sorptivity tests were employed to measure concrete's resistance to the effects of aggressive environments and examine the durability properties. The most performed grade samples were analyzed as individual microspheres with Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDXS), and X-ray diffraction. Significant improvements in various concrete properties were achieved through the partial replacement of fly ash and GGBS with cement. Doi: 10.28991/CEJ-2022-08-04-05 Full Text: PDF

Published: May 2022

Indeed, natural processes of discarding rubber waste have many disadvantages for the environment. As a result, multiple researchers suggested addressing this problem by recycling rubber as an aggregate in concrete mixtures. Previously, numerous studies have been undertaken experimentally to investigate the properties of rubberized concrete. Furthermore, investigations were carried out to develop estimating techniques to precisely specify the generated concrete's characteristics, making its use in real-life applications easier. However, there is still a gap in the conducted studies on the performance of the k-nearest neighbor algorithm. Hence, this research explores the accuracy of using the k-nearest neighbor's algorithm in predicting the compressive and tensile strength and the modulus of elasticity of rubberized concrete. It will be done by developing an optimized machine learning model using the aforementioned method and then benchmarking its results to the outcomes of multiple linear regression and artificial neural networks. The study's findings have shown that the k-nearest neighbor's algorithm provides significantly higher accuracy than other methods. This kind of study needs to be discussed in the literature so that people can better deal with rubber waste in concrete. Doi: 10.28991/CEJ-2022-08-04-06 Full Text: PDF
