Scheduling as a Constraint Satisfaction Problem (Using the Example of Open-Pit Minе Production Scheduling Problem)
Authors: Zuenko Alexander , Oleynik Yurii
Published: September 2024

The research described in the work is aimed at developing methods for Scheduling. The fundamental disadvantage of the existing methods of Mixed-Integer Linear Programming in application to the problems under consideration is the fact that they are too demanding on the amount of RAM. The difficulty of applying local search procedures to such high-dimensional problems is to develop an effective way to find an acceptable initial approximation and determine the neighboring state transition function, which would allow achieving the optimum fast enough. In the Operations Research Theory, adding additional conditions to a problem can lead to a fundamental change in the problem-solving scheme. The methods proposed in the study are implemented within the framework of the Constraint Programming Paradigm which makes it possible to represent the subject domain dependencies saving RAM, as well as to provide the ability to step-by-step take into account heterogeneous problem conditions without essentially changing the scheme of finding solutions. A significant part of the research deals with methods of logical inference on constraints to reduce the search space and speed up the computational process. The approach to scheduling is illustrated by the Open-Pit Mine Production Scheduling Problem, which was first proposed to be solved as a Constraint Satisfaction Problem. In order to find the first feasible solution, a «greedy» search method is proposed, the result of which can be improved using the developed hybrid method. Both methods rely on original procedures of inference on constraints. The proposed approach has proven its efficiency for block models with sizes of tens and hundreds of thousands of blocks.
An Approach to a Priori Assessment of Fuzzy Classification Models in Monitoring Tasks
Authors: Potyupkin Alexander , Pilkevich Sergey , Zaytsev Vsevolod
Published: September 2024

The article addresses the problems of using automation tools to perform monitoring and management tasks applicable to assessing the quality of fuzzy classification models, where the classification procedure is implemented on the basis of knowledge (rules) in the absence of the training set. An approach is proposed to obtain a priori assessments of the classification quality based on the study of the used model sensitivity to changes in the values of internal parameters during the corresponding modeling. The interpretation of the modeling results in the form of risk assessment caused by the self-imperfection of the classification models is obtained. The article provides an example of a fuzzy classification model based on a comparison of the current state of a monitoring object described using fuzzy features with a set of predefined typical states, which form corresponding fuzzy equal (close) states (monitoring situations). The comparison is carried out using the fuzzy implication operation provided that the required reliability is met. The example of this model demonstrates how the type of implication operation, as well as the internal features of the model, affect the results of classification, and appropriate indicators are proposed, which are both an interpretation of generally accepted indicators for assessing the classification quality, and unique, inherent in the considered model. Computational experiments were carried out, which made it possible to obtain graphs of changes in classification quality assessment indicators for the considered model and its modification and visualize the influence of internal parameters of the model on the results of its application. A number of indicators are proposed that allow for an a priori assessment of the risks arising from the application of the model before its actual application.
Development of a Linear Control System for a Throttle of a UAV Propeller-Motor Group
Authors: Voevoda Alexander , Filiushov Yuriy , Filiushov Vladislav
Published: September 2024

Orientation and positioning control of an unmanned aerial vehicle (UAV) vertical take-off and landing multi-rotor type in space is inextricably linked with the formation of a motion control vector, consisting of a combination of thrusts and aerodynamic moments of each propeller-motor group. The accuracy and speed of formation of the motion control vector greatly affect the positioning and orientation errors of the UAV. Most works devoted to the synthesis of UAV control systems use a motion control vector without taking into account the dynamics of the rotor-motor groups, which in some cases forces the control system to reduce its performance. The performance of the UAV control system can be increased by increasing the speed of generation of the thrust of the propeller-motor groups, for which a system for controlling the thrust of the propeller-motor group has been proposed. The propeller-motor group in its composition has a nonlinear internal connection in the aerodynamic torque and an output signal – thrust, that nonlinearly depends on the square of the propeller rotation speed. Typically, the propeller group is controlled like an electric motor – the internal coupling of the aerodynamic torque is considered an external disturbance, and the thrust is controlled by changing the speed of rotation of the propeller which is calculated based on the required motion control vector. It is proposed to consider thrust and aerodynamic torque an integral part of the propeller-engine group, for which to build a linear thrust control system. For this purpose, we carried out feedback linearization of the rotor-motor group system, connecting the voltage supplied to the motors with the motion control vector, which is the output value. The linearization process is divided into two stages: at the first stage feedback linearization is performed for an electric motor with internal nonlinear coupling by aerodynamic torque; at the second stage, linearization is performed with feedback on the output obtained at the first stage of the system with a nonlinear output signal – thrust. In accordance with the principles of subordinate control, motor control is formed for linearized feedback of the propeller group. Simulation was completed. An important issue when using feedback linearization is the preservation of the quality characteristics of the control system in the event of a mismatch between the parameters of the object and the model, the parameters of which are used to calculate the linearizing feedback. In this work, modeling was carried out with a discrepancy of some parameters up to 50%.
Implicit Understanding: Decoding Swarm Behaviors in Robots through Deep Inverse Reinforcement Learning
Authors: Iskandar Alaa , Hammoud Ali , Kovács Béla
Published: September 2024

Using reinforcement learning to generate the collective behavior of swarm robots is a common approach. Yet, formulating an appropriate reward function that aligns with specific objectives remains a significant challenge, particularly as the complexity of tasks increases. In this paper, we develop a deep inverse reinforcement learning model to uncover the reward structures that guide autonomous robots in achieving tasks by demonstrations. Deep inverse reinforcement learning models are particularly well-suited for complex and dynamic environments where predefined reward functions may be difficult to specify. Our model can generate different collective behaviors according to the required objectives and effectively copes with continuous state and action spaces, ensuring a nuanced recovery of reward structures. We tested the model using E-puck robots in the Webots simulator to solve two tasks: searching for dispersed boxes and navigation to a predefined position. Receiving rewards depends on demonstrations collected by an intelligent pre-trained swarm using reinforcement learning act as an expert. The results show successful recovery of rewards in both segmented and continuous demonstrations for two behaviors – searching and navigation. By observing the learned behaviors of the swarm by the expert and proposed model, it is noticeable that the model does not merely clone the expert behavior but generates its own strategies to achieve the system’s objectives.
Synthesis of a Fuzzy Controller by a Second-Order Object with Delay
Authors: Shilin Alexander , Pham Trong Hai , Nguyen Vuong Van
Published: September 2024

The paper proposes a method for using Fuzzy controller tools to synthesize optimal control of a second-order dynamic object with a delay. The idea is to construct a phase surface that combines optimal relay control away from the equilibrium state region and linear control in the region itself. This approach made it possible to avoid self-oscillations in a steady state while maintaining the properties of optimal control in terms of speed. The switching trajectory in phase space, corresponding to the solution of the optimal control problem according to the Maximum principle, is determined by the method of inverse time calculation of the second-order difference equation of the plant. The region near the equilibrium state, where the linear controller is used, is determined from the results of modeling the motion of a point in phase space with optimal control for an object with a delay. This region is represented by an ellipse that describes motion in phase space in a self-oscillatory mode. To further eliminate self-oscillations in this area, a linear controller is used, tuned by means of solving the variational optimal control problem. It is proposed to use a tool for the synthesis of Fuzzy controllers, where the switching surface and calculation of the control value can be set arbitrarily. As a result, a variable controller structure is proposed to combine these two approaches. The resulting Fuzzy controller model is represented by a standard FLS structure, which was implemented in Python on the Orange Pi embedded computer. To connect to the current control object, an industrial controller FX3U-24MR is used, connected to a computer via a Modbus network. Full-scale tests are presented on a hot water supply temperature control object, which corresponds as closely as possible to the object model under study. The method, idea and results obtained in the work can be applied and investigated in the synthesis of control of dynamic objects in sliding mode to solve current problems related to eliminating the unwanted Chattering effect.
Movement and energetics of swimming marine mollusks
Authors:   ,   Massachusetts Institute of Technology, Cones Seth F. ,   Woods Hole Oceanographic Institution
Published: September 2024

Mollusks constitute a significant proportion of marine animal biomass and fulfill essential ecosystem functions. Yet, our knowledge of their behavior and energy output in natural environments remains elusive. This key knowledge gap stems from our inability to quantify their positions and movements for appreciable time-scales, and thus we know extremely little about how abundant mollusks that are pervasive in all ocean biomes respond to naturally varying and anthropogenically-induced changes. In this thesis, I adapted emerging biologging sensor technology, traditionally designed for large robust vertebrates, for two key mollusk taxonomic groups (squid and scallops) to quantify and characterize movements at fine-temporal scales. In Chapter 2, I collected the first high-resolution (> 1 Hz) in situ movement data for any squid species. These novel data elucidated fundamental swimming behaviors such as swim direction, postures, and environmental extents of ecologically-vital diel vertical migration. In Chapter 3, I linked lab-calibrated bioenergetic models and field observations to map energy output and necessary caloric intake of natural behaviors in the wild. These data revealed dynamic gait use on seconds time scales. Next, in Chapters 4 and 5, I quantified the behavioral disruption and the metabolic cost of a prominent anthropogenic stressor, sound pollution. Squid and scallops elicited drastically different ecophysiological responses to field-simulated offshore windfarm construction. Squid elicited dramatic behavioral responses coinciding with the onset of construction, although animals habituated rapidly. Contrarily, scallops’ behavioral responses were moderate but consistent, and surprisingly there was no evidence of habituation across second, minutes, and daily time scales. Extended behavioral changes manifested as heightened metabolic rates and weakened antipredator responses, suggesting prolonged and potential population-level impacts on a key fishery. This thesis provides new insight in marine invertebrate movement ecology and eco-physiology, demonstrating the utility of coupling biologging and physiological experiments to reveal how key ocean animals behave and expend energy.

The text is a presentation of the preliminary results of team research on the attitude of students towards the value of the renewal of social order, reconstructed in Piotr Sztompka’s “renewal decalogue”. On the basis of the results of the exploration carried out 30 years ago on “Youth in relation to the values and norms of social life”, a new scientific research was designed. It was carried out at several Polish and Ukrainian universities, in a group of students from several faculties. Ten values and forty norms of social life were assessed twice on a six-point scale. The respondents were first asked to indicate to what extent they considered certain values of social life as personally important and how they influenced their lives in various social situations. Then, they had to assess to what extent the given norms are noticed in their environment and are present in contemporary social life. The research report contains the results of the exploration of only a part of the study cohort, 272 students of pedagogy from Polish universities and 91 students from pedagogical universities in Ukraine. The obtained results were additionally compared with those obtained three decades earlier in a group of students of the same faculty.
Motywacje studentów pochodzących z Europy Wschodniej do studiowania w Polsce – kontekst międzynarodowy, lokalny i instytucjonalny

The article comprises a presentation of the motivations that accompany students coming from Belarus, Lithuania, Russia, and Ukraine when deciding to study in Poland. The theoretical framework for examining the motivation of foreign students’ migration decisions is the push-pull factors model by Everett Lee. The analyzed material comes from an online survey of foreign students studying at the University of Wroclaw and the Maria Curie Sklodowska University in Lublin in December 2022 and January 2023. The study focuses on the factors that attract foreign students to specific destinations in three contexts: international (why Poland?), local (why a particular city?), and institutional (why a particular university?). The pull factors of greatest importance for foreign students from both universities turned out to be economic and cultural ones. The evaluation of the level of democracy in Poland was also significant. Taking into account the local context, it is worth noting that Wroclaw and Lublin attract not only with their original educational offer but also with their “urban atmosphere,” a “climate” conducive to ethnic difference. Social networks – understood as having family or friends in the country, the city of study or the chosen university – turned out to be the least important for the decision to study in Poland.
Strategie przetrwania uczniów-uchodźców z Ukrainy (w percepcji nauczycieli z liceów ogólnokształcących)
Authors:   Uniwersytet WSB Merito w Gdańsku, Biernat Tomasz
Published: September 2024

The aim of the article was to identify and characterize survival strategies adopted by Ukrainian refugee students in general secondary schools. The study was grounded in qualitative research within the interactionist perspective, with the use of thematic analysis. The empirical material was collected through in-depth narrative interviews with twelve teachers from six schools located in cities of various sizes. The research revealed and described three main strategies employed by refugee students: distancing strategy (from teachers, education, and peer groups), engagement avoidance strategy (in classwork and homework), and non-learning of the Polish language strategy. The primary function of these strategies was to simulate the performance of school duties and assume the role of a learner. The strategies were students’ responses to the imposed situation of sudden and compulsory functioning in school in a foreign country, without knowledge of the teaching language and without preparation for participation in advanced secondary education. The strategies constituted a response to the lack of systemic, flexible, and functional solutions stimulating the adaptive processes of refugee students. The article concludes with practical implications regarding the necessity of developing a coherent concept of education for refugee students, as well as migrants who do not present sufficient competence in the Polish language at the secondary level.
NARRATIVAS DISCENTES A PARTIR DO ENSINO DA DANÇA NA EDUCAÇÃO FÍSICA ESCOLAR
Authors: Costa Igor Henrique da , Campos Priscila Augusta Ferreira
Published: September 2024

Este artigo explora a experiência de 10 estudantes do Ensino Médio com o conteúdo de danças na Educação Física Escolar, analisando suas narrativas. Utilizando uma abordagem qualiquantitativa, as narrativas discentes foram coletadas por meio de entrevistas semiestruturadas e complementadas com observações em diário de campo. Esse método visou obter uma visão mais abrangente e contextualizada das percepções e vivências dos estudantes em relação à dança. A análise de conteúdo revelou que muitos alunos reconhecem a importância da dança para o desenvolvimento físico e cultural, mas há uma tendência de afastamento dessa prática, especialmente entre os meninos. Fatores como vergonha, diferenças de comportamento entre gêneros, a influência do ritmo musical, dos movimentos corporais e o bullying foram identificados como elementos que afetam significativamente a participação dos estudantes nas atividades de dança. A pesquisa sugere a necessidade de repensar a abordagem pedagógica do ensino da dança, adotando estratégias mais inclusivas e sensíveis às questões de gênero. As narrativas discentes demonstraram ser uma ferramenta eficaz na produção de dados para compreender o fenômeno da dança no contexto escolar e orientar práticas pedagógicas mais inclusivas e adaptadas às realidades dos alunos.

Investigation on bond behavior in post-tensioned RC slabs
Authors: Azami Vahid , Nazarpour Hadi , Dehestani Mehdi
Published: September 2024

This study investigates the effect of various parameters including concrete compressive strength, prestressing load level, CFRP strengthening, and tendon eccentricity on the load capacity and bond behavior of post-tensioned RC slabs strengthened with CFRP. The load-displacement behavior was experimentally determined and the results were verified. A follow up FEM study was performed on concrete-CFRP interfacial stress and strain distributions, as well as CFRP slippage and damage evolution contours. Based on the results, tendon eccentricity has the greatest effect on load capacity of slabs. Besides, increasing the prestressing load level increases the secant flexural stiffness, but decreases ductility. A 54% increase in prestressing load results in a 64% enhancement in slab stiffness. Also, the yield and maximum loads increase by increasing prestressing load. This is particularly advantageous in slabs strengthened with thinner CFRP laminates, at which slippage of the laminate is very common.
Agroecologia e Identidade Quilombola: a agroecologia na construção da identidade sociocultural da Comunidade Quilombola de Rincão dos Negros – Rio Pardo/RS
Authors: Karnopp Erica , Quadros Alessandra de , Cadoná Marco André
Published: September 2024

O artigo apresenta uma análise sobre o significado sociocultural de práticas agroecológicas em Comunidades Quilombolas. Tomando como referência a Comunidade Rincão dos Negros, localizada no município de Rio Pardo, no Rio Grande do Sul, indica-se que as práticas agroecológicas se inserem num contexto de resistências e de afirmação da identidade sociocultural das Comunidades Quilombolas. Na Comunidade Rincão dos Negros, o manejo de saberes e de práticas tradicionais, comprometidos com a segurança alimentar e a conservação da biodiversidade, remete a diferentes formas de manipulação e de negociação de sistemas de significados, códigos de referências que tecem a formação identitária. As práticas agroecológicas, nesse contexto, compreendem a produção e a reprodução de mecanismos de defesa de práticas e de conhecimentos tradicionais e locais, não implicando somente a identificação dos aspectos técnicos do potencial endógeno do local, mas também as lutas sociais, políticas, culturais que a Comunidade Quilombola estabelece com o objetivo de construir sua própria identidade sociocultural.
O papel dos movimentos sociais rurais na trajetória do Programa Nacional de Fortalecimento da Agricultura Familiar (PRONAF)
Authors: Lopes Indaia Dias
Published: September 2024

Este trabalho tem como objetivo identificar a atuação dos movimentos sociais rurais nas diferentes etapas do Pronaf, buscando identificar a atuação da Fetag-RS e da Fetraf-Sul no programa. Trata-se de uma pesquisa exploratória, com abordagem qualitativa dos dados coletados por meio de livros, artigos científicos e legislação. As políticas públicas constituem-se no resultado de construções e conflitos sociais e, nessa perspectiva, o Pronaf foi construído a partir de um longo processo de lutas, reivindicações, acontecimentos e várias outras situações que possibilitaram a implementação desse programa. Ao longo dos anos, os movimentos sociais rurais adotaram posturas distintas que refletiram na trajetória dessa política pública. Na década de 1980, antes mesmo da criação do Pronaf, predominou uma postura reivindicatória, que mudou na década seguinte para uma postura propositiva. No início dos anos 2000, adotou-se uma postura colaborativa, com a participação desse segmento no Ministério do Desenvolvimento Agrário, processo denominado de cogestão das políticas públicas. Após 2010, esse cenário não se manteve e o que se observa é uma acomodação desses movimentos. A análise das pautas da Fetag-RS e da Fetraf-Sul realizada por alguns autores indica que essas organizações vêm direcionando seus esforços para um perfil de agricultor familiar em transição ou consolidado, buscando ampliar as bases da agricultura familiar.

Published: September 2024

Este artigo trata da memória sobre a comida do passado por meio de relatos de pessoas inseridas na categoria de velhos/idosos no Brasil, aquelas acima de 60 anos. Envolvem recordações sobre como eram a alimentação e a comida da infância. Todas as 14 pessoas com quem conversamos optaram por falar das memórias ligadas, sobretudo, ao afeto e aos bons momentos, mesmo quando entremeavam no relato algumas dificuldades de escassez alimentar ou de pobreza.  Foram entrevistadas pessoas idosas com idade entre 65 e 84 anos. Todas elas residentes da região Sudoeste do Paraná, a maioria é descendente de italianos, alemães e poloneses. Quase todas nasceram no Rio Grande do Sul ou em Santa Catarina e se mudaram para a referida região depois de adultas, quando da política da Marcha para Oeste, do governo Getúlio Vargas em início da década de 1940. As lembranças trouxeram curiosidades a respeito de práticas alimentares, modos de fazer e uso de termos sobre comida onde mesclam a língua originária dos seus avós/pais, colonos, com a língua portuguesa, criando dialetos. Os depoimentos foram em vários momentos emotivos, trazendo muitas lembranças agradáveis, e outras nem tanto, mas foram considerados pelas idosas (os) que se dispuseram a contar um momento importante, tido como uma oportunidade de falar um pouco do passado para pessoas interessadas em escutá-las. O método foi qualitativo, usando a ferramenta principal da história oral.
Verbalizando o despertar da consciência de resistência à sujeição cultural: insurgir-se para desaprender e reaprender

A partir de 1960 vários países do continente africano proclamaram as suas “independências” política e administrativa do jugo colonial, fruto de conquistas efetivadas por um lado, por meio de negociação pacífica e por outro lado, pela luta armada. E foi por meio desta última que os moçambicanos alcançaram a independência nacional, à 25 de Junho de 1975. Pensadores e teóricos pós-coloniais movidos pela constatação da prevalência das colonialidades de poder vêm questionado as independências. É nesse viés que tecemos esse artigo, com objetivo de suscitar algumas reflexões que promovam e potencializam debates sobre a imposição cultural enraizado no sistema colonial, sustentado pelos discursos preconceituosos eurocentrados que buscavam incutir e enfatizar o mito de complexo de inferioridade atribuído aos homens negros; tanto como impor a homogeneização cultural eurocêntrica. Esses debates são embasados teórica e metodologicamente por viés pós-coloniais e decoloniais. Por meio de revisão bibliográfica, dialogamos com Fanon (2020) Cesáire (2020), Azagaia (2013), Ki-Zerbo (2010) Lopes (2010) e; vários autores para discutir as colonialidades que perpassam o tecido social dos moçambicanos. Portanto, das reflexões constata-se que as colonialidades podem ser desestabilizadas por meio de ações efetivas de desaprendizagem e reaprendizagem: desaprender as amaras ideológicas eurocêntricas “romper a dominação mental”, denunciar e insurgir-se contra a subalterinização, alienação cultural e desmascarar os paradigmas, estereótipos, preconceitos eurocêntricos e aprender a reconquistar e revalorizar as identidades socioculturais nativas, aprender a pensar e falar sobre o continente africano com os africanos.

20 anos da criação do Fórum de Desenvolvimento Integrado e Sustentável da Mesorregião Metade Sul do Rio Grande do Sul: uma análise sobre sua criação, atuação e legado no âmbito da Política Nacional de Desenvolvimento Regional
Authors: Zanon Joana Silvestrin
Published: September 2024

O presente artigo aborda a Política Nacional de Desenvolvimento Regional (PNDR) a partir do marco de vinte anos da criação do Fórum de Desenvolvimento Integrado e Sustentável da Mesorregião Metade Sul do Rio Grande do Sul (Fórum da Mesosul), no âmbito dos Programas de Desenvolvimento Integrado e Sustentável de Mesorregiões Diferenciadas, do extinto Ministério da Integração Nacional. A questão regional já estava presente na política brasileira desde a República Velha, adquirindo renovada importância a partir da Constituição Federal de 1988 e da retomada do papel do governo federal como promotor de políticas públicas a partir de 2003. O propósito da PNDR era promover uma melhoria na qualidade de vida da população residente nas treze mesorregiões selecionadas, através de fóruns e projetos locais, que promoveriam a gestão das ações propostas pelos Programas. Assim, o presente artigo tem por objetivo analisar a PNDR e a atuação do Fórum da Mesosul em uma perspectiva histórica, pautada na revisão documental e de literatura, contribuindo com subsídios ao debate sobre a retomada de uma política nacional de desenvolvimento regional no Brasil. No contexto da PNDR, o Fórum da Mesosul significou um importante ganho em termos de articulação dos atores regionais, constituindo-se em um espaço de debates e de divulgação de projetos e resultados. Apesar destes avanços, os objetivos de desenvolvimento integral e sustentável da região não foram atingidos, e o Fórum se desintegrou, merecendo investigação mais aprofundada.

Graph models occupy an important place in tasks related to information protection and information security, including in the construction of models and methods for managing the continuous operation and recovery of systems, and countering denial of service. We consider a finite dynamical system (Γkn, α), n ⩾ 1, the states of which are all possible orientations of the complete graph Kn, and the evolution function is specified as follows: the dynamic image of the digraph is a digraph obtained from the original one by reorienting all the arcs included in the sinks; there are no other differences between the original digraph and its image. Formulas are obtained for calculating the number of cyclic (belonging to attractors) states of the system; states that are not cyclical; attractors of the system, including various types. The corresponding tables are given for n from 1 to 20 inclusive.
Combinatorial properties of the bounded knapsack problem

The combinatorial properties of the set of solutions to the bounded knapsack problem are considered. As in the general case, this problem is an NP-complete combinatorial optimization problem and its exact solution requires the use of search algorithms with the decomposition of a set of feasible solutions. In this regard, the question of determining and evaluating the properties of the set of acceptable solutions to the problem is relevant. In this paper, formulas are obtained which allow to calculate the average value of the functional of a problem on the set of its feasible solutions and the power of this set through the number of solutions of subtasks of smaller dimension. The basic technique for obtaining results is the method of generating functions. We also consider the knapsack problem with arbitrary values of variables, in which the coefficients of the constraint vector and the objective function coincide. For this, the “continuity” of the set of solutions is assumed. Estimates of the values of the functional in this problem are found. The results may be of interest for the design of computational algorithms for finding and estimating the number of solutions and the value of the functional for optimal solutions. The expressions found can also be used in auxiliary procedures to evaluate the optimality of the solution in decomposition or heuristic algorithms for solving the knapsack problem.
Modern dictionary of French and Russian pseudoequivalents
Authors:   Ural Federal University, Tomilova Aleksandra I.
Published: September 2024

The article deals with the problem of interlingual pseudoequivalnce, which is considered to be part of interlingual interference and includes interlingual homonyms, heteronyms, “false friends” of translators/interpreters, etc. This topic has generated scientific interest for several decades but still has not received sufficient theoretical coverage, which represents the relevance of the topic, on the one hand. On the other hand, the importance of connections between lexicography and other sciences leads to the creation of new types of dictionaries including dictionaries of pseudoequivalents. The author overviews the existing dictionaries of the translator's “false friends” mostly for students on the example of different languages and describes in detail principles of creating a modern dictionary of pseudoequivalents on the example of the French and Russian languages (1721 pairs in total), taking into account grammatical, lexical, etymological, extralinguistic characteristics of the lexemes that form a pseudoequivalent pair, lexicographic approaches at the intersection of translation studies, lexicology and other linguistic sciences based on the data of explanatory and translation dictionaries, which makes it appropriate for the use of professional translators, not only for students. To reach this aim, the author uses a combination of methods: a comparative method as the main one, contextual and lexicographic analysis, a continuous sampling method to find pseudoequivalents, observation, comparison, classification, generalization, systematization, and quantitative calculation. The vocabulary entries, which are systemized alphabetically by French lexemes, present information about the type of pseudoe-quivants based on different criteria: lexical meaning (absolute, partial and contextual pseudoequivalents), form (graphical, phonetical, and phonetic-graphical pseudoequivalents), etymology (common, direct, reciprocal, indirect and disputable pseudoequivalents), and part-of-speech belonging (pseudoequivalets of the pair belong to the same, different, or several parts of speech). The study advances the project of a modern dictionary with three full examples and aims to also include phycholinguistical meanings resulted from phycholinguistical association experiments, which will lead to a deeper understanding of the volume of the meaning of pseudoequivalents and help avoid false analogies while translating and interpreting even more. The author declares no conflicts of interests.

This work used the Finite Element Method (FEM) to estimate the shear force for a blind shear ram type blowout preventer. In recent years, significant advancements have been made in the design of Foot Over Bridges (FOBs) through the utilization of advanced analytical methods, innovative materials, and novel bridge concepts. FOBs have gained popularity in urban India due to their ability to facilitate safe pedestrian crossings without disrupting vehicular traffic flow, thereby enhancing pedestrian safety in areas with heavy traffic. This research focuses on the development of an economically optimized steel FOB design specifically tailored for the Mumbai region. The primary objectives are to ensure durability, stability, safety, and cost-effectiveness in the design. The study involves modelling the typical span of a skywalk structure using STAAD Pro, followed by comprehensive analysis and design iterations for various configurations based on real-world spans of existing pedestrian bridges. Static loading conditions are applied to the FOB models, allowing important characteristics like weight, number of joints, number of members, weld lengths, painting surface area, and natural frequency of pedestrian bridges to be evaluated. These factors are carefully contrasted to determine the bridge design that is the most economical. Additionally, vibration tests are conducted on two selected skywalks to assess their compliance with serviceability criteria. The research scrutinizes the utilization ratio of members in the bridge structures and explores variations in section sizes within the design to achieve the optimal configuration. The findings are presented in detail, offering valuable insights into the process of identifying the most economical FOB design from the skywalks in the Mumbai suburban region. This study contributes to the enhancement of pedestrian infrastructure in urban India by delivering a robust and cost-efficient FOB design approach.
The Effect of Partial Shadings on the Output Power of the Photovoltaic Modules Connected with Different Current and Voltage Characteristics
Authors: Sara Ira Devi , Aqsa SH Aidil , Tarmizi Tarmizi
Published: September 2024

A mismatch in the output power of photovoltaic (PV) modules in a PV array can occur due to partial shading or a module replacement. Substitution of a module in a PV array with a new one might lead to different current and voltage characteristics between the new and existing modules and result in power losses. The amount of power loss might be increased more if the PV array experiences partial shading. For this reason, this study aims to investigate the effect of partial shadings on the power output of photovoltaic arrays with different current and voltage characteristics. The PV array under test consists of 25 units of solar modules with a total cross-tied (TCT) configuration. There are five shading conditions applied to the test PV array, i.e., the short narrow (ShN), the short wide (ShW), the long narrow (LnN), the long wide (LnW), and the diagonal. A magic square method is applied to reduce the power loss when the PV modules experience partial shading conditions. The results show that the power loss due to partial shadings, either on all identical modules or partially identical, is the same. The most significant power loss occurs in the long comprehensive shading scenario, where 80% of the modules experience shading, which is 41.30%.

Monitoring turtle behavior is a conservation effort to preserve its habitat, and the detection process is a vital initial stage. On the other hand, robotics demands a deep learning network to automatically detect the presence of sea turtles that can operate in real-time. The need for increased model speed in the inference stage has led to many lightweight vision-based detectors. This work proposes a novel turtle detection to localize multiple sea turtles using a deep learning method. A lightweight primary extractor is applied to distinguish crucial features without producing a huge computational. An excited group attention is offered as an enhancement module that can capture essential turtle components in multi-level convolutional patches. A new turtle dataset is proposed that contains lighting, blur, occlusion, and complex background challenges. The evaluation results show that the proposed model performs higher accuracy than other lightweight object detection models. High-efficiency benefits models that can be implemented on low-end devices in terms of real-time data processing speed.
