Published: December 2024

Background and Objectives Adductor spasmodic dysphonia (ADSD) is a disease in which symptoms such as voice break, strained voice, and voice tremor occur during vocalization due to abnormal spasms of the adductor muscles of the vocal cords. In this study, we aimed to confirm the clinical effectiveness of recently developed Korean items for the differential diagnosis of ADSD and muscle tension dysphonia (MTD).Materials and Method Twenty patients who were diagnosed with ADSD and improved with treatment were set as the ADSD group, 7 patients diagnosed with MTD and received voice therapy as the MTD group, and 7 normal patients without voice disorders were set as the control group, and the medical records and voice test results were compared and analyzed. Recently developed Korean questions were read by the patient, and the degree of voice tremor, strained voice was evaluated. In addition, the recorded voice was analyzed with a spectrogram.Results A statistically significant difference between the two patient groups was confirmed in the auditory perceptual evaluation of voiced sentences and phrases, tense voiceless sentences and phrases of Korean items. Spectrogram analysis revealed that voice breaks were more frequent in the ADSD group during voiced sentences, and wide-spaced vertical striations were more prominent in the ADSD group during voiced sentences, phrases, and tense voiceless phrases.Conclusion It was confirmed that Korean items for the differential diagnosis of ADSD are useful in identifying speech task specificities in ADSD patients through spectrogram analysis as well as auditory perceptual evaluation.

Published: December 2024

Este artigo tem como tema a aprendizagem organizacional em agências de comunicação. O objetivo é identificar a contribuição da aprendizagem organizacional nos processos criativos da Brivia Dez Comunicação. Entende-se que a aprendizagem organizacional beneficia os processos criativos das agências de comunicação e que a criatividade deve ocorrer de maneira satisfatória na rotina desses profissionais. A partir disso, realizou-se uma pesquisa descritiva, qualitativa com entrevista em profundidade em 2021, totalizando seis profissionais das áreas criativas da agência. Como resultado identificou-se que existe uma aprendizagem organizacional na agência. E, que a agência se preocupa e incentiva a disseminação de conhecimento, mas essa ocorre de maneira frágil especificamente nos times criativos, ao mostrar que fatores como diferenças na formação das tribos, nos líderes, perfil de cliente e fluxo de trabalho podem ser pontos de atenção a serem observados pela agência para garantir uma fluidez e eficácia. Também foi possível validar as informações da fundamentação teórica que evidencia que somente a intenção de gerar uma aprendizagem organizacional não é suficiente, sendo importante respeitar os fatores e processos gerando uma prática contínua e satisfatória.

Authors: Silva Filipe Valença e , Sales Jefferson David Araújo
Published: December 2024

O presente estudo tem como objetivo investigar a percepção dos idosos acerca das dimensões/aspectos da conscientização em segurança da informação em um ambiente corporativo, identificando fatores de afastamento dessas pessoas às melhores práticas de proteção à informação em uma empresa pública sergipana. Utiliza-se como estratégia um estudo de caso qualitativo único, incorporado, de abordagem descritiva e exploratória, com dados coletados mediante entrevistas orientadas por um roteiro semiestruturado e por observação das atividades da empresa. Os dados são analisados via análise de conteúdo. Dentre os fatores de afastamento às melhores práticas em segurança da informação, verificam-se: limitado contato com os especialistas de tecnologia da informação da empresa, que tende a proporcionar intercâmbio de conhecimentos técnicos aderentes a boas práticas em segurança da informação; reduzida percepção técnica das ameaças à segurança da informação, não tendo consciência do alcance dos danos de um comportamento inseguro; um menor grau de comprometimento com os objetivos de segurança da informação da organização, representado pela ausência de preocupação com possíveis prejuízos à empresa, sendo suas preocupações voltadas somente a prejuízos pessoais; comunicação deficiente por parte da gestão de tecnologia da organização; falta de envolvimento de gestores da organização; e baixa adesão a treinamentos, influenciada possivelmente por baixo interesse e sensação de baixa autoeficácia na operação de dispositivos digitais. A nível de pesquisas futuras, recomenda que se conduzam estudos semelhantes em empresas privadas, avaliando possíveis diferenças nas percepções dos idosos nesses ambientes, sobretudo em aspectos comportamentais e de processos.

A inovação e a aprendizagem organizacional no judiciário brasileiro
Authors: Ferreira Fernanda Gomes , Rados Gregorio Jean Varvakis
Published: December 2024

A inovação é estudada como um instrumento para melhorar a prestação dos serviços ao cidadão e o desempenho das instituições públicas, enquanto que a desaprendizagem organizacional é apresentada como alavancadora da capacidade de inovar. O objetivo é o de investigar a gestão da inovação no Poder Judiciário Brasileiro a partir da teoria da desaprendizagem organizacional. A metodologia escolhida foi a pesquisa de campo de caráter quantitativo e em delineamento do tipo survey, com aplicação de questionário eletrônico, que teve como construtos, a partir da pesquisa bibliográfica e documental: aprendizagem organizacional e conhecimento organizacional; memória e esquecimento organizacional; mudança organizacional e inovação. O questionário foi aplicado para a população alvo de 1160 indivíduos cadastrados na Plataforma da Rede de Inovação do Poder Judiciário, resultando em 200 respondentes, sendo os dados analisados estatisticamente. A pesquisa evidenciou que há reconhecimento de que os Tribunais são inovadores. Contudo, revelou haver indícios de que os princípios da teoria da desaprendizagem ainda não são totalmente compreendidos ou assimilados. Não há concordância expressiva de que desaprender é tão importante quanto adquirir novos conhecimentos. Pela pesquisa, a gestão da inovação no Poder Judiciário tem como vantagem o reconhecimento da existência de conhecimento e/ou rotinas ineficazes e obsoletos e a abertura para assimilação do novo. Por outro lado, os desafios para a gestão da inovação no Judiciário estão relacionados com a resistência a mudanças e o descarte intencional de conhecimento e/ou rotinas ineficazes e obsoletos. Uma ênfase na desaprendizagem organizacional poderá impulsionar a gestão da inovação no Judiciário.
Analysis of rural transformation trajectories in the post-soviet society: A spotlight on Dagestan
Authors: Imangulov Linar , Safronov Sergey , Savoskul Maria
Published: December 2024

The article analyzes the spatial features of the post-Soviet socio-economic
transformation of rural areas of southern Russia with the Republic of
Dagestan as an example. The limited availability of reliable statistical
data determined the need to organize five expeditions to Dagestan from 2020
to 2024. The results of the expeditions revealed a high spatial
heterogeneity of rural development in the region. The presence of vast
mountainous and the specifics of post-Soviet modernization of society and
economy determine a particular nature of development of rural Dagestan. The
classification procedure allowed identifying 10 types of districts in rural
Dagestan with significant differences in their basic characteristics. The
analysis of the dynamics of the main socio-economic indicators of Dagestan
rural areas within different geographical, social, and economic types
emphasized that a comprehensive analysis of the transformation of mountain
territories should consider both the specific features of mountains and the
factors of population and economy modernization. The study has shown that
rural Dagestan has two main trajectories of socio-economic transformation of
territories in the post-Soviet period, i.e., inertial and modernization.
Together they demonstrate matching of such processes as the archaization and
modernization of the local economy structure, and traditionalization and
modernization of the society. It has been revealed that the inertial
trajectory of rural transformation dominates in mountainous and piedmont
rural areas, while the modernization one dominates in the plains. This is a
serious challenge for the spatial development of the region.
Exploring the spatialization of culture: Perspectives from Slovenian ethnology
Authors: Slavec-Gradisnik Ingrid
Published: December 2024

The article presents observations on the intricate processes of localizing
peoples and cultures, drawing on their spatial mapping, a practice known
since antiquity. The introducing part outlines general views on the causal
relationship between culture and environment. The Enlightenment put forward
the hypothesis of environmental determinism, which provided a rationale for
linking people, cultures, and geographies well into the 20th century,
particularly in anthropogeography and culturearea research. The isomorphism
of space/place and culture characterized research until the late 20th
century when the postmodern turns called it into question. The theory of
practice and the spatial turn proved particularly influential in
anthropology and ethnology. In this field, the central concept of culture
has been deconstructed; this has stimulated debates about ethnography as a
genre of ?writing culture? and fieldwork as a locally grounded research
practice. The second part of the text shows how Slovenian ethnology in the
20th century pursued cultural area research shared with other European
regional or national ethnologies that focus on the national territory.
However, research has not shown a clear correspondence between cultural and
ethnic/national boundaries. In this respect, ethnology has maintained a
critical distance from cultural essentialization. On the other hand, it has
not particularly reflected upon space; space has functioned as the natural
environment, the obvious background of culture. In this respect, the
reception of the spatial turn brought a particular sensitivity to studying
spatial practices and experiences and refining research methodologies.
Numerical simulation on NOx reduction in the float glass furnace with gradient oxygen-enhanced combustion
Authors: Jin Mingfang , He Feng , Xie Junlin , Mei Shuxia
Published: December 2024

To reveal the influence of using gradient oxygen-enhanced combustion on the
gas flow, combustion status, heat transfer and nitrogen oxide (NOx) emission
in glass furnace, numerical simulation on the flame space of an actual float
glass furnace with air combustion was conducted. The streamline of
combustion-supporting gas and flue gas was displayed, the temperature
distribution and heat transfer performance in the flame space were analyzed,
and the mechanism of NOx emission reduction by gradient oxygen-enhanced
combustion was explored. The comparative study between air combustion and
gradient oxygen-enhanced combustion showed that there is not much difference
in the streamline and temperature distribution in flame space, which ensures
the stability of working state in furnace. Compared with air combustion, the
temperature of the batch zone was increased by using gradient
oxygen-enhanced combustion, and the high-temperature combustion zone was
closer to the glass surface, which increases the radiant heat flux to the
glass surface. In addition, the NOx emission concentration in flue gas at
the outlets was reduced by 17.1%. The results obtained in this study not
only provide important theoretical guidance for gradient oxygen-enhanced
combustion in glass furnace, but also lay a foundation for further research
about advanced combustion mode to save energy and reduce emissions.
Everything about the Prebiotics and Probiotics and their Effect on Public Health
Authors: FAE* Shaltout
Published: December 2024

The human gut is home to trillions of bacteria, fungi, and other microorganisms, collectively known as the gut microbiota. These
microorganisms play a crucial role in digestion, immune function, and even the regulation of mood and metabolism. Prebiotics
and probiotics are two key components that significantly influence the health and composition of the gut microbiota. While
prebiotics are substances that stimulate the growth of beneficial bacteria in the gut, probiotics are live beneficial bacteria that
can provide health benefits when consumed in adequate amounts.

Published: December 2024

Artificial Intelligence aims to create intelligent devices that resemble humans by inducing intelligent behavior. This study aims
to examine the senior high school students’ perceptions and awareness on the ethical implications of artificial intelligence
in terms of age, sex, and grade level. The study utilized a quantitative cross-sectional research design. The respondents of
the study were 142 senior high school students currently enrolled in a public secondary high school in Eastern Philippines
of the school year 2024-2025 and selected using stratified and systematic random sampling techniques. The study used
an adapted survey questionnaire. Results revealed that senior high school students have a high perception and awareness
towards ethical implications of artificial intelligence. Furthermore, result showed that there is a significant difference in terms
of age of senior high school towards perceptions and attitudes on the ethical implications of artificial intelligence and there
is no significant difference between perceptions and awareness in terms of sex and grade level. The study concludes that
while students are largely optimistic about AI in education, proactive measures are crucial to ensure responsible and fair use
of this technology. Further research should focus on addressing resource inequalities and translating ethical concerns into
concrete policies and practices. The study emphasizes how urgently proactive steps must be taken to guarantee the ethical and
responsible application of artificial intelligence in education, including addressing resource disparities and converting moral
considerations into tangible rules and procedures. This highlighted a potential access to AI resources and training, raising
concerns about equitable implementation.

Published: December 2024

The relevance of the study of young people’s economic behaviour features is beyond doubt, because the younger generation is the future social capital and economically active population of any country. The purpose of the presented study was to identify the specifics of proactive behaviour and economic activity (as indicators of economic behaviour), their demonstration and interrelation among Russian and Chinese students. One hundred and two Russian and Chinese students took part in the study. The following techniques were used: 1) “Proactive behaviour” Methodology by A.I. Yerzin; 2) “Questionnaire of economic activity” by E.V. Zabelina and Yu.V. Chestyunina; 3) “Questionnaire of subjective economic well-being” by V.A. Khashchenko; 4) “Monetary attitudes” Questionnaire by B. Klonts and T. Klonts adapted by D.A. Bayazitova and T.A. Lapshova. Mathematical analysis methods: Mann-Whitney U-test and Spearman’s rank correlation coefficient. The results showed that the indicators of proactive behaviour demonstrated by the Russian students were higher than those demonstrated by Chinese students. The cognitive economic activity indicators were higher among the Chinese students. The Chinese students appeared to be more vigilant and careful with finances. The Russian students showed better results in experiencing a lack of financial resources. The specificity of economic behavior in Russian students is manifested through internal behavioral determination and constructive proactivity. Chinese students demonstrate cognitive economic activity and responsibility in relation to money. Based on the acquired results, the paper presents recommendations for the Russian and Chinese students’ economic behaviour development and correction.

ROBOTICS AS A FACTOR IN THE TRANSITION TO GREEN AGRICULTURE
Authors:   Don State Technical University, Rostov-on-Don, Russian Federation, Marchenko S.A.
Published: December 2024

This article discusses the process of automation of agriculture, its significance and benefits for the technological environment and agricultural sector of a state. Automated systems are able to work alongside humans, performing part of their work, and in some cases, they can completely autonomously carry out the entire production process. They can process plots by ploughing, fertilizing, and sowing. However, the introduction of such advanced technical and technological solutions as automated systems requires significant financial investment at the initial stages of their implementation in agriculture. These systems rely on a range of components, including sensors, which allow them to navigate through space, identify objects, analyze information, and make predictions. They also utilize software, data storage, and communication systems to process information. Robotic technology replaces manual labor and the operation of agricultural machinery, under the supervision of human operators, enabling farmers to cater to various market demands and enhance the value of their crops.

The design of modern technical systems, for example, thermal power plants, refrigeration units, requires preliminary modeling of the dynamics of the installation at the design stage. When modeling technical systems, problems arise in the analysis of heterogeneous dynamic processes. This requires special software for the numerical analysis of modeling problems. Individual processes may exhibit high dimensionality combined with rigidity and hybrid behavior, requiring specialized numerical solution methods. High technical complexity requires problem-oriented graphical and textual languages as part of tools for modeling heterogeneous dynamic processes. As a specific example of such systems, the problem of modeling thermal-hydraulic networks with high dimensions, branching and associated computational difficulties is considered.

Authors: Nurramadhani Annisa , Riandi Riandi , Permanasari Anna , Suwarma Irma Rahma
Published: December 2024

STEM learning has increasingly been implemented in higher education, particularly in science education programs. In the aftermath of the global health crisis, the learning process has transitioned to a new normal, significantly different from pre-crisis practices. Numerous changes and challenges have emerged in science learning, particularly in fostering collaboration among prospective teachers in higher education. This research explores the nature of collaboration among prospective science teachers through the integration of STEM learning, employing a qualitative research method with in-depth observation as the primary data collection technique. Observations were conducted directly and supported by video recordings to ensure comprehensive data collection, with collaborative practices assessed using collaborative learning rubrics. The findings reveal that science education students have improved their collaboration skills through STEM learning integration, showing greater comfort in direct discussions and hands-on investigative learning activities, although some topics still require online discussions facilitated by e-learning platforms. Consequently, a blended learning approach is identified as the most effective method for integrating STEM learning in the current era to enhance collaboration in science education. Future research could further investigate the integration of STEM learning using hybrid learning models to promote collaboration among students.

This study aims to understand night markets as informal educational spaces through an analysis of the concept of deterritorialization from Deleuze and Guattari. As dynamic spaces, night markets are not only an arena for economic transactions, but also a space for cultural interaction, knowledge exchange, and the formation of community identity. This study uses a qualitative approach with participatory observation methods and in-depth interviews with visitors to night markets. The data obtained are then analyzed using a deterritorialization framework to describe how night markets go beyond the formal boundaries of education, creating a fluid and creative learning space. The results of the study show that night markets are an arena for deterritorialization of education, where local values and knowledge, negotiation skills, and cultural adaptation are distributed organically. Night markets show the blurring of the boundaries between economic space and educational space, making them an alternative learning locus that is not bound by formal institutions. In addition, the process of deterritorialization in night markets goes beyond traditional understandings of education by showing that knowledge and learning can thrive in marginal and temporary spaces. This study contributes to the discourse on informal education and marginal spaces, and opens up opportunities for further exploration of the role of non-formal spaces in building a learning society. The night market, as a site of deterritorialization, serves as a concrete example of how education can occur outside institutional control, offering an inclusive and flexible alternative for the dissemination of knowledge.
La construcción del juego como objeto de enseñanza. Dilemas y desafíos en la educación física escolar
Authors: Saredo Federico
Published: December 2024

Se propone compartir los avances teórico-reflexivos de la línea de investigación “estudios sobre lo lúdico y el juego en la praxis educativa”, junto a las experiencias de orientación de la práctica preprofesional de la Licenciatura en Educación Física ISEF-UdelaR, en relación con la enseñanza del juego en el sistema educativo escolar. Si en “el jugar por jugar” la intervención docente se limita a contemplar el juego y en “el jugar para” interviene tanto que el juego se diluye, estas perspectivas dicotómicas no resuelven el problema su enseñanza. Parece necesaria la construcción de un objeto de enseñanza “juego” como saber de la EF y el docente como mediador de este capital cultural.

Analysis of observability and detectability for CSTR model of biochemical processes under uncertain system dynamics and various sets of measured outputs
Authors: Łangowski Rafał , Czyżniewski Mateusz
Published: December 2024

An analysis of observability and detectability for continuous stirred tank reactor model of selected biochemical processes has been addressed in this paper. In particular, properties of observability or detectability of the considered system model have been proved under uncertain system dynamics in view of various sets of system measured outputs. It is related to considering system dynamics depending on initial conditions and the impact of inputs taking into account a given measured output. The method of indistinguishable state trajectories (indistinguishable dynamics) and tools based on the Lyapunov second method were used to investigate the observability and detectability properties. The analysis was performed for eight cases of different sets of measured outputs with association to the realistic features of measuring devices. The obtained research results are essential for system state estimation that involves the synthesis of state observers. The proposed approach may be successfully applied to the complex biochemical non-linear uncertain systems modelled as continuous stirred tank reactors.

Internal model control based sliding mode controller design for unstable second order delayed processes with a case study on CSTR
Authors: Ali Mohammed Hasmat , Anwar Md Nishat
Published: December 2024

Controlling the unstable processes is challenging since one or more poles are located on the right side of the s-plane. The existence of dead time in these systems makes control much more difficult. In this paper, internal model control based sliding mode control has been proposed for the control of unstable processes with dead time. Two sliding surfaces based on PID and PIDPI are used to design of the proposed controller. The parameters of continuous and discontinuous control law are obtained using differential evolution optimization technique. An objective function is constituted in terms of performance measure (integral absolute error) and control effort measure (total variation of controller output). Illustrative examples demonstrate the superiority of the proposed controller over earlier reported work in this realm, especially in terms of load disturbance rejection. A case study on temperature management of a continuous stirred tank reactor during an irreversible exothermic process also serves to highlight the applicability of the proposed system. Furthermore, robustness of the proposed controller is also investigated by inclusion of perturbations in the parameters. The obtained results clearly show how well the suggested controller works.
Improving the Attractiveness of Waste Steel Cans for Steel Mills by Removing Tin
Authors: Gajda B.J. , Reterski J.
Published: December 2024

The ever-increasing amount of municipal waste due to the rising demand for consumer goods presents a significant challenge in finding new, effective methods for material recovery and recycling. A considerable proportion of these materials are steel cans made of tin-coated steel sheets. Tin, being a metal with broad applications and limited natural resources, should be recovered from waste materials. Recovering/removing tin from waste steel cans would make them a more attractive raw material for steel mills. Processes for recovering tin from the surface of steel sheets in used cans mainly rely on hydrometallurgical methods. This paper presents the results of tin recovery from steel sheets using leaching with a 1M NaOH solution at 90°C. Tests were conducted on the removal of paint and varnish layers that inhibit the tin removal process. The results show that it is possible to improve the efficiency of tin recovery from cans through chemical treatment, which will significantly increase steel mills' interest in this type of waste as a valuable input for metallurgical processes and a source of iron. Closing the loop in a closed circuit involved the electrolysis of tin from the leaching solution.

Published: December 2024

The following paper deals with the multipole design of the switched reluctance motor (SRM). The design is intended to facilitate the four-channel operation of the motor. Due to multipole design of the rotor and multichannel operation abilities, there are numerous possible configurations for powering the poles in each phase. Analysis of selected such configurations was carried out, including multichannel (MC) operating conditions (e.g. single-channel operation (SCO)). A mathematical model of three-phase MC SRM is presented. The static electromagnetic torque characteristics were obtained together with the self- and mutual inductance characteristics. Selected laboratory test results are presented in the paper.

Authors: Jankowski Szymon , Bober Waldemar
Published: December 2024

The design of responsive structures has evolved significantly, establishing itself as an interdisciplinary field characterized by a fully customized ideation process. To streamline and unify this process, a novel method for modeling the behavior of rod-like responsive structures using an evolutionary algorithm is introduced. The proposed mathematical framework leverages key geometric and physic parameters to control the generative process, enabling adaptability and fluidity in form development. By employing an evolutionary algorithm, the method offers an alternative to conventional rigid and repetitive morphing models, providing flexibility and innovation in responsive design outcomes. The developed model supports independent learning and fosters originality in solutions at both architectural and urban scales. Moreover, the presented methodology serves as the foundation upon which the authors developed the model, enabling its application across a wide spectrum of responsive structures for users. This paper addresses challenges in spatial modeling, behavioral algorithms, and the implementation of responsive architecture, presenting the author’s innovative model for rod-like responsive structures alongside performance analysis. The methodology demonstrates promising results in terms of adaptability and efficiency, with potential for further refinement to enhance speed and output quality. Research also describes challenges and risks for further development of responsive models implementation.

Published: December 2024

Drones have become common devices that are increasingly used, from toy mini-drones to very advanced autonomous flying platforms used in various industries. The safety of using engineering structures and the need to shorten the time of carrying out diagnostic activities, and thus reduce costs, force the use of innovative tools to carry out an automated and unmanned process of assessing the technical condition of existing engineering structures, especially large-size ones, including bridges strengthened with external FRP (Fibre Reinforced Polymer) composite overlays. There are conventional methods for assessing the technical condition of existing building structures carried out by inspectors and experts, involving the use of typical inspection and diagnostic tools. During the research, it was found that it is possible to carry out an automated and unmanned process of assessing the technical condition of engineering structures using an unmanned flying platform equipped with a thermal imaging diagnostic device. The uniqueness of the presented solution is that the drone is equipped with a docking module that allows the drone to be temporarily attached to the structure being diagnosed for the duration of diagnostic activities. To ensure appropriate conditions for structural diagnostics, a unique system of automated diagnostic process and a multi-stage structure of the control system in all phases of operation were developed. The article presents a solution for the control system based on control consistent with the reference model. In particular, the focus was on the difficult and dangerous issue of altitude control during the docking phase. Simulation tests carried out in the Matlab/Simulink environment, as well as laboratory and field tests on a real drone, proved the correctness of the proposed solutions, which enabled the undisturbed operation of the diagnostic module.
On optimization of an adaptive pneumatic impact absorber – the innovative rescue cushion

Published: December 2024

The paper states a complex study on the adaptive rescue cushion and concerns a problem of efficient impact mitigation, which is present during evacuation or assurance of people conducted by fire brigades. In order to minimize negative effects of person’s fall from height an airbag system is applied. Unfortunately, until now only passive solutions have been used. As a result, loads acting on a landing person were not minimized, because passive systems are designed for predefined, extreme conditions. Since the authors proposed to introduce adaptation mechanisms into the rescue cushion, a number of issues arose. They include construction and control of release vents, taking into account the inaccuracies of estimated impact parameters, and optimization of the venting area in case the evacuated person lands outside the airbag’s center. All these problems were addressed within this paper and described in detail. Discussion on the system adaptation and its optimization was preceded by experimental validation of a numerical model. The energy absorbing capabilities of widely used passive rescue cushions were significantly enhanced as a result of the conducted research.

Published: December 2024

This paper describes research on a prototype of a multi-axis force and torque sensor dedicated to the support system of a telescopic camera crane arm. Based on studies conducted on an actual telescopic camera crane arm., the requirements that the sensor must meet to enable precise control of the drives in two working axes of the telescopic camera crane arm were defined. In the developed sensor, a method for measuring forces and torques using an optical displacement sensor was proposed. A simplified sensor prototype was made to verify the assumptions, and measurement tests were carried out. Additionally, the paper presents a CAD model of the sensor using an elastic pin, based on which a numerical model was developed, and calculations of displacements and mechanical stresses were performed.
