Fault Diagnosis of an Excitation System Using a Fuzzy Neural Network Optimized by a Novel Adaptive Grey Wolf Optimizer
Authors: Fu Xinghe , Guo Dingyu , Hou Kai , Zhu Hongchao , Chen Wu , Xu Da
Published: September 2024

As the excitation system is the core control component of a synchronous condenser system, its fault diagnosis is crucial for maximizing the reactive power compensation capability of the synchronous condenser. To achieve accurate diagnosis of excitation system faults, this paper proposes a novel adaptive grey wolf optimizer (AGWO) to optimize the initial weights and biases of the fuzzy neural network (FNN), thereby enhancing the diagnostic performance of the FNN model. Firstly, an improved nonlinear convergence factor is introduced to balance the algorithm’s global exploration and local exploitation capabilities. Secondly, a new adaptive position update strategy that enhances the interaction capability of the position information is proposed to improve the algorithm’s ability to jump out of the local optimum and accelerate the convergence speed. In addition, it is demonstrated that the proposed AGWO algorithm has global convergence. By selecting real fault waveforms of the excitation system for case validation, the results show that the proposed AGWO has a better convergence performance compared to the grey wolf optimizer (GWO), particle swarm optimization (PSO), whale optimization algorithm (WOA), and marine predator algorithm (MPA). Specifically, compared to the FNN and GWO-FNN models, the AGWO-FNN model improves average diagnostic accuracy on the test set by 4.2% and 2.5%, respectively. Therefore, the proposed AGWO-FNN effectively enhances the accuracy of fault diagnosis in the excitation system and exhibits stronger diagnostic capability.
Optimization of Ansys CFX Input Parameters for Numerical Modeling of Pump Performance in Turbine Operation
Authors: Černý Jan , Polák Martin
Published: September 2024

The paper deals with the issue of determining the optimal setting of input variables in Ansys CFX for modeling pump flow in turbine operation (PAT). The pump model was created in Autodesk Inventor. The mesh for numerical simulations was created using Ansys Fluent Meshing, considering the mesh quality parameters’ skewness and aspect ratio. The Ansys CFX computational model was experimentally verified on an actual pump by measuring the performance parameters on a test circuit and using the PIV (particle image velocimetry) method. The research indicated that the most suitable setting for the model input variables was the inlet pressure and PAT flow rate combination. Another option was to adjust the pressure at the pump inlet and outlet. However, the calculation time in this case was up to 30% longer. The comparison of the model results with the experiment showed that the deviations in the numerical model performance values did not exceed 10% of the values measured on the test circuit. Only the calculated torque was 1.2 ± 0.13 Nm higher on average than the torque measured on the test circuit. This difference is most likely due to the simplification of the geometry of the computational mesh in order to reduce the computation time.

Published: September 2024

The present work proposes a spectrophotometric method for deltamethrin determination using silver nanoparticles (AgNPs). The AgNPs are spherical with a diameter of~11 nm and a negative surface charge with zeta potential ranging from −4.1 mV (pH 2) to −48 mV (pH 10). The AgNP colloidal system showed greater stability at higher pH values and for a molar ratio of 6 between the sodium borohydride and silver nitrate in the synthesis. This is because the borate ions from the oxidation of borohydride are present on the surface of the nanoparticles, promoting an electrostatic repulsion between them which keeps them dispersed. The method was validated, obtaining satisfactory results of veracity and precision, and the limits of detection and quantification were 0.17 and 0.51 mg L−1, respectively. The method was selective for deltamethrin compared to the compounds cypermethrin, endosulfan, thiamethoxam, atrazine, chlorpyrifos and parathion. Deltamethrin promotes the formation of dendritic silver nanostructures, changing the color of the system. The results demonstrate the development of a reliable and selective method for the detection of deltamethrin using AgNPs.
Adsorption of Methylene Blue and Eriochrome Black T onto Pinecone Powders (Pinus nigra Arn.): Equilibrium, Kinetics, and Thermodynamic Studies
Authors: Solmaz Alper
Published: September 2024

In this study, methylene blue (MB) and eriochrome black T (EBT) dyes were removed with the waste Pinus nigra Arn. powders from Anatolian black pinecone (PC-PnA) within the framework of sustainability. UV–Vis spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray (EDX), fourier transform infrared spectroscopy (FTIR), thermogravimetry–differential thermal analysis (TGA-DTA), Brunauer–Emmett–Teller (BET) surface area, and point of zero charge (pHpzc) analyses were performed for the characterization of PC-PnAs. The effects of pH, amount of adsorbent, time, initial concentration and temperature were determined by batch adsorption experiments. Four kinetic and isotherm models were examined, and error function tests were used for the most suitable model. According to this, the average pore diameters, mass losses at 103.9 and 721.6 °C and pHpzc values of PC-PnAs were found as 61.661 Å, 5.9%, 30%, and 5.77, respectively. Additionally, the most suitable kinetic and isotherm models for the removal of both dyes were Langmuir and pseudo-second-order. The maximum removal efficiencies (qmax) for MB and EBT dyes was calculated as 91.46 and 15.85 mg/g, respectively and the adsorption process was found to be endothermic. As a result, PC-PnA particles can be used as an alternative sorbent for the removal of MB and EBT dyes.
Can Systematic Theology Be Saved? Doctrine and Its Discontents
Authors: Clark-Howard Andrew
Published: September 2024

This paper explores recent discussions on the nature and character of Christian doctrine and doctrinal arrangement within leading accounts of systematic theology, that is, the attempt to offer an integrated and cohesive account of the central commitments of the Christian faith. Through such discussion, I argue that the perennial epistemological problem systematic theology faces in its attempts to speak about a (divine) object who definitionally exceeds such speech is related to the specific ethical problem of systematic theology’s performances as a hegemonic discipline, one which often functions to exclude non-white, non-male perspectives. In light of these challenges, I contend that “positive” reasons for continuing systematic theology remain remote; systematic theology cannot be saved. Yet neither can it be avoided, lest such problems are willfully repeated and because of the ways systematic theology continues to be a leading site of doctrinal reflection within Christian education and intellectual reflection. I therefore conclude this paper by exploring two apocalyptic responses to the crises facing systematic theology which advocate for its continuation precisely by calling for its “end”.
The Role of Networked Narratives in Amplifying or Mitigating Intergroup Prejudice: A YouTube Case Study
Authors: Kim Daum , Kokuryo Jiro
Published: September 2024

This purpose of this research is to understand the role of networked narratives in social media in modulating viewer prejudice toward ethnic neighborhoods. We designed experimental videos on YouTube based on intergroup contact theory and narrative frameworks aimed at (1) gaining knowledge, (2) reducing anxiety, and (3) fostering empathy. Despite consistent storytelling across the videos, we observed significant variations in viewer emotions, especially in replies to comments. We hypothesized that these discrepancies could be explained by the influence of the surrounding digital network on the narrative’s reception. Two-stage research was conducted to understand this phenomenon. First, automated emotion analysis on user comments was conducted to identify the varying emotions. Then, we explored contextual factors surrounding each video on YouTube, focusing on algorithmic curation inferred from traffic sources, region, and search keywords. Findings revealed that negative algorithmic curation and user interactivity result in overall negative viewer emotion, largely driven by video placement and recommendations. However, videos with higher traffic originating from viewers who had watched the storyteller’s other videos result in more positive sentiments and longer visits. This suggests that consistent exposure within the channel can foster more positive acceptance of cultural outgroups by building trust and reducing anxiety. There is the need, then, for storytellers to curate discussions to mitigate prejudice in digital contexts.
Airbnb and Urban Housing Dynamics: Economic and Social Impacts in Greece
Authors: Kourkouridis Dimitris , Rizos Apostolos , Frangopoulos Ioannis , Salepaki Asimenia
Published: September 2024

This study examines the interplay between Airbnb and gentrification in Thessaloniki and Greece, focusing on their economic and social impacts on urban neighborhoods. Utilizing data from 110 online publications and qualitative insights from ten semi-structured interviews with real estate agents, Airbnb stakeholders, residents, and experts, the research provides a nuanced view of these dynamics. The findings suggest that Airbnb influences housing markets by driving up rental and home prices, potentially exacerbating housing scarcity and displacing vulnerable populations in gentrifying areas. While this aligns with the existing literature, the results remain tentative due to the complexities involved. The trend toward corporate-hosted short-term rentals appears to shift Airbnb away from its original community-focused model, though this shift is still evolving. The COVID-19 pandemic introduced changes, such as a move from short-term to long-term rentals and the conversion of commercial spaces to residential use, impacting neighborhood dynamics. However, these effects may be temporary and do not fully address broader housing issues. While an oversupply of Airbnb accommodations might stabilize rental prices to some extent, its impact on the overall housing crisis remains uncertain. Future research should investigate the long-term effects on housing affordability and social equity, considering the limitations of current findings.

Published: September 2024

Este artigo tem como objetivo discutir os mecanismos de coesão textual nos anos iniciais do Ensino Fundamental, segundo abordados na Base Nacional Comum Curricular (BNCC) e nas proposições de uma coleção de livros didáticos de Língua Portuguesa voltados para essa fase. Trata-se, portanto, de uma pesquisa documental qualiquantitativa, cujas análises se concentraram nas habilidades especificadas no documento normativo que contemplam explicitamente o conhecimento em foco, bem como na forma como os livros didáticos operam o ensino e a aprendizagem do conteúdo, considerando as práticas de linguagem e os recursos e estratégias destacadas nas atividades sugeridas. A pesquisa aponta para a relevância de propostas didáticas contextualizadas e significativas, o que foi, em certa medida, evidenciado nas abordagens de dispositivos gramaticais em articulação com o desenvolvimento da competência textual-discursiva dos estudantes. Entretanto, também foram identificadas lacunas e desafios nas práticas pedagógicas indicadas nos livros didáticos, evidenciando, portanto, a importância de uma reflexão crítica contínua sobre os materiais didáticos e a formação de professores.
Freudian psychic apparatus and Luria's functional units: exploring intersections.
Authors: Moreira de Souza Adriano Junio
Published: September 2024

Introduction. In this paper, we aim to point out that Freudian concepts such as the id, ego, and superego may find equivalents in neuroanatomy/neurobiology. To this end, we explore the possible intersections between Sigmund Freud's psychoanalytic theoretical model and neurologist Alexander Luria's model of functional units. Although Freud distanced himself from the strictly localizationist neurological perspective of brain functions, his notions of the mind as a dynamic phenomenon persist and continue to inspire discussions in the field of neuroscience. Method. We establish a parallel between Freud's structural and dynamic model and Luria's model of functional units, highlighting the complex relationship between the id, ego, superego, and the neurological framework. Results. We emphasize that, although precise locations for these structures may be elusive, a systemic neuroscientific approach to psychic activity aligns with Freud's vision. Additionally, we explore the genetic and neurobiological dimensions of Freud's proposal and discuss how these elements could lead to a deeper understanding of neuropsychic structures. We argue that the distinction between the id and its differentiated structures remains nebulous, and that the id may have roots in brain regions governing basic survival, with origins in genetic inheritance. Conclusion. This paper does not provide definitive answers but aims to contribute to the complex relationship between Freudian psychoanalysis and neurobiology. We emphasize the imperative need for future investigations, particularly employing a microscopic/reductionist approach to neuropsychic differentiation.

A evolução dos sistemas celulares, do ponto de vista da camada física de rede, aponta para a convergência entre comunicações sem fio e comunicações ópticas. Tal convergência possibilita aproveitar simultaneamente a mobilidade e flexibilidade dos sistemas sem fio e a elevada capacidade dos sistemas ópticos. Em paralelo, algoritmos de Inteligência Artificial (IA) tendem a ser promissores para o controle efetivo e dinâmico dos inúmeros parâmetros das redes, cada vez mais densas e heterogêneas. Neste contexto, o presente trabalho reporta um sistema rádio sobre fibra (radio over fiber-RoF) inovador, assistido e otimizado por IA. Propõe-se o uso de computação evolutiva para reduzir as degradações do sistema RoF, visando sistemas da quinta e sexta geração de comunicações móveis (5G e 6G). Resultados numéricos para diferentes ordens de modulação demonstram a aplicabilidade da ferramenta proposta, por meio da melhora na taxa de erro de símbolos (symbol error rate- SER) do sistema RoF.

Published: September 2024

A doença cardíaca reumática (DCR) é o resultado pós-inflamatório da febre reumática, que pode ser desenvolvida após um quadro de faringite. A cavidade oral dos seres humanos é colonizada por diversos agentes infecciosos que, sob certas circunstâncias, como a má higiene, podem acometer tecidos circundantes e levar a infecções sistêmicas, e a higiene oral inadequada pode ser um fator desencadeador da infecção orofaríngea que contribui para o desenvolvimento dessa doença. O comprometimento das válvulas cardíacas que frequentemente é causado pela DCR, traz um risco elevado de endocardite infecciosa, causada pelo processo de migração de bactérias para a corrente sanguínea denominado de bacteremia, que pode ser agravado pelo grau de inflamação e infecção presentes nos tecidos orais. Portanto, pacientes com má higiene oral e focos de infecção bucal possuem maior risco de desenvolver endocardite, sendo necessária a assistência odontológica, pois a adequação do meio bucal realizada pelo cirurgião-dentista, bem como a prescrição da profilaxia antibiótica prévia a procedimentos odontológicos (quando necessário) podem diminuir o risco de bacteremia.

Published: September 2024

Background: Rotavirus is the most common cause of gastroenteritis among children. Currently, four oral live-attenuated vaccines are available to prevent rotavirus infection. The World Health Organization (WHO) has recommended including rotavirus vaccination in national immunization programs; however, it has not been introduced to the Iranian national immunization program. The study aimed to assess the frequency of rotavirus gastroenteritis in the west of Iran and investigate the necessity of rotavirus vaccination. Study Design: A case series study. Methods: In this case series study, 284 cases under six years of age who presented with acute gastroenteritis from March 2021 to 2022 to a referral hospital in the west of Iran were evaluated. Data on baseline characteristics, clinical manifestations, results of stool test, ELISA for rotavirus detection, and polymerase chain reaction (PCR) test for genotyping of rotavirus-positive samples were recorded. Results: Results showed that the prevalence of rotavirus infection was 36.6%. The highest frequency was observed among children aged 6-12 months and during the autumn. According to the PCR results, G1P[8], G9P[8], G9P[4], and G1P [4] were the dominant genotypes, and 33.75% of samples were infected with multiple rotavirus genotypes. Conclusion: The study highlights the considerable prevalence of rotavirus infection among cases of acute gastroenteritis in children under six years of age who were referred to a referral hospital in the west of Iran and the high diversity of rotavirus genotypes in the targeted community. Consequently, physicians and health policymakers should prioritize strategies for the prevention and control of this infection, particularly by considering the rotavirus vaccine as a priority for the Iranian national immunization program.

Reliable, sensitive, and accurate tests are needed to assess animal models of brain injury. The Garcia score is a neuro behavioral measure that has been used in many murine studies. However, despite its widespread use, there are no detailed video descriptions of the steps to properly perform and grade the Garcia test on rats. Consequently, there has been significant variation in its performance and reliability, calling for greater standardization. The Garcia score is comprised of six measures: spontaneous activity, symmetry in the four limbs, fore paw outstretching, climbing, body sensation, and response to vibrissae touch. Each component is scored with a minimum of zero or one and a maximum of three, with the highest total score of 18. This report systematically and clearly describes how each component of the Garcia score is performed and graded with an accompanying video illustration. The purpose of this report is to assist researchers in implementing the Garcia test and to help standardize the use of this measure across studies.

Objective: To date, no novel drug therapies have proven effective in improving outcomes after intracerebral hemorrhage (ICH). This has been slowed, in part, by a lack of reliable preclinical models that recapitulate the pathophysiological consequences of ICH. Limited descriptions of the methodology of preclinical models may play a role in this failed translation. The current study aimed to improve the autologous blood injection model of ICH and provide a comprehensive methodology to facilitate a reliable preclinical model that bridges the translational research gap.
Methods: A modified single-injection protocol for an autologous-blood ICH model was developed and tested. This rodent ICH model produces injury in the basal ganglia of adult rats via a stereotaxically-assisted right-sided single-injection of fresh autologous whole blood. A comprehensive step-wise description of the methodology is presented and documented in a written and visual format with supporting pictorialmaterial, to prevent common mistakes that result in failed hematoma formation.Rates of successful hematoma formation using the single-injection protocol, outlined here, were compared to those using the traditional double-injection protocol.

La popularización de la cultura alemana en Argentina: Editorial Claridad y Alejandro Korn como mediadores (1922-1949)
Authors:   , De Oro Camila
Published: September 2024

La presente investigación doctoral tiene como propósito indagar en la recepción popular que se ha hecho de la cultura alemana en Argentina a través de dos mediadores culturales que propiciaron la divulgación de obras y pensadores germanoparlantes entre los sectores populares argentinos. La primera mediación es efectuada por Editorial Claridad, fundada por Antonio Zamora en la Buenos Aires de 1922 en el marco del ideario socialista con el propósito de promover el acceso al libro y la lectura entre los sectores sociales que, de otra manera, no podían comprar su material de lectura y, por consiguiente, de instrucción. La segunda figura mediadora es Alejandro Korn, médico, profesor y filósofo argentino de ascendencia alemana, quien a lo largo de su vasta trayectoria académica y política, participó de diferentes instancias educativas divulgando el pensamiento filosófico, en términos generales, y las ideas de autores germanos, en particular. Como se desarrollará en esta pesquisa, tanto el proyecto de Zamora como el de Korn tienen puntos en común e incluso, llegan a articularse hacia la década de 1930. Por ese entonces, el filósofo se afilió al Partido Socialista y, a partir de ese momento, Claridad inicia la publicación de las obras kornianas. En este sentido, la tesis profundiza en la convergencia y retroalimentación entre ambos proyectos político-pedagógicos a través de los cuales no sólo se divulgó la cultura alemana en el territorio argentino, sino también se contribuyó a la difusión del pensamiento de Korn, al enaltecimiento de su figura y a consagrarlo como el gran filósofo nacional.

Authors: Qiu Zhichao
Published: September 2024

The study aimed to explore the key factors influencing the academic achievement of nursing students. Emphasizing the human capacity for self-directed learning and behavior, this research investigates the impacts of school values, teaching and learning, interest in courses, and learning engagement on students' academic achievement. The study aims to assess the current levels of these variables, design and implement Intervention Design Implementations (IDIs) to enhance them, and determine any changes in these variables before and after the implementation of IDIs. The research design was a sequential exploratory mixed-methods design, combining qualitative and quantitative methods to develop an instrument for data collection. With a sample size of 378, the target population was nursing students from higher vocational education in Shanghai, with a sample size of 378 students. Preliminary findings revealed that the school's values, teaching, and learning, interest in courses, and learning engagement were generally low. A multiple regression analysis showed that school value (p<0.05), teaching and learning (p<0.05), interest in a course (p<0.05), and learning engagement (p<0.05) significantly predicted academic achievement. Experts developed and validated a theoretical model based on the findings, laying the groundwork for future interventions aimed at enhancing nursing students' self-regulated learning capability. The study aimed to explore the key factors influencing nursing students' academic achievement in higher vocational education in Shanghai, China.

The study aimed to explore the key factors influencing the self-efficacy of nursing students. Emphasizing the human capacity for self-directed learning and behavior, this research investigates the impacts of mastery experience, vicarious experience, social persuasion, regulation of emotions, and anxiety on students self-efficacy. The study aims to assess the current levels of these variables, design and implement self-development plans to enhance them, and determine any changes that occur before and after the implementation of these plans. The research design was a sequential exploratory mixed-methods design, combining qualitative and quantitative methods to develop an instrument for data collection. The target population consisted of nursing students from vocational colleges in Shanghai, with a sample size of 435 students. Preliminary findings revealed that the students' self-efficacy, mastery experience, vicarious experience, social persuasion, regulation of emotions, and anxiety levels were generally low. A multiple regression analysis showed that mastery experience (p = 0.000<.005), vicarious experience (p = 0.000<0.05), social persuasion (p = 0.000<0.05), regulation of emotions (p = 0.000<.001), and anxiety (p = 0.04<0.05) significantly predicted self-efficacy. Experts developed and validated a theoretical model based on the findings, laying the groundwork for future interventions aimed at enhancing nursing students' self-efficacy.

This study aims to explore the factors affecting students' learning performance in blended learning in nursing and vocational education. Emphasizing the human capacity for self-directed learning and behavior, this research investigates the impacts of learning motivation, behavioral engagement, cognitive engagement, emotional engagement, agentic engagement, and feedback on students' learning performance. The study aims to assess the current levels of these variables, design and implement intervention strategies (strategic plans) to enhance them, and determine any changes in these variables before and after the implementation of the strategic plan. The research design was a sequential exploratory mixed-methods design, combining qualitative and quantitative methods to develop an instrument for data collection. The target population consisted of nursing students from three public colleges in Shanghai, with a sample size of 1494 students. Preliminary findings revealed that the learning motivation, behavioral engagement, cognitive engagement, emotional engagement, agentic engagement, and feedback levels were generally low. A multiple regression analysis showed that learning motivation (p<0.01), behavioral engagement (p<0.01), cognitive engagement (p<0.01), emotional engagement (p<0.01), agentic engagement (p<0.01), and feedback (p<0.01) significantly predicted learning performance. Experts developed and validated a theoretical model based on the findings, laying the foundation for future interventions to enhance nursing students' learning performance.
DEVELOPMENT OF A LEADERSHIP COMPETENCY MODEL FOR PRINCIPALS IN PRIMARY SCHOOLS IN SHANGHAI, CHINA
Authors: Sun Xiaonan , Asavisanu Poonpilas
Published: September 2024

The effective running of schools requires principals to possess leadership competence. In the Chinese context, the selection of principals is based on criteria established by the government, not necessarily the demonstration of leadership ability. Therefore, school principals may still need to enhance their leadership competencies. The goal of this study is to create a leadership competency model specifically for primary school principals in Shanghai. The study was structured around four key objectives: 1) To determine the leadership competencies needed for primary school principals; 2) To determine the factors that affect principal leadership competency development in primary schools in Shanghai; 3) To find the gap between current and needed leadership competencies for primary school principals in Shanghai; and 4) To develop a model of leadership competencies for primary school principals in Shanghai. We used an exploratory mixed-methods design, utilizing both interviews with principals and a survey of 1,113 teachers.
The qualitative content analysis revealed eight competencies from the literature: collaboration, communication, educational administration, time management, adaptability, diversity and inclusion, self-awareness, and well-being. Factors that affect competency development were discovered during interviews with principals. Results of the Priority Needs Index (PNI) found that the top three competencies in need of development were collaboration, communication, and educational administration competence. Expert intuition facilitated the development and validation of a model. This model aims to serve as a guide for primary school principals in Shanghai, enhancing their leadership competencies.
AN IMPACT OF GAME-BASED TEACHING ON VOCABULARY LEARNING OF THIRD GRADE STUDENTS IN SHENZHEN QIANHAI ELEMENTARY SCHOOL
Authors: Ma Xiaoya , Lertlit Supinda
Published: September 2024

This research discussed game-based teaching in third-grade English as an entry point and proposed corresponding teaching strategies for existing problems. The objectives of this research were: 1) to find out the impact of game-based teaching on the English vocabulary learning of the third-grade students in Shenzhen Qianhai Elementary School; and 2) to find out the satisfaction level of third-grade elementary school students with the use of game-based teaching methods to improve their English learning. This study aims to inspire third-grade English educators. According to the analysis of the data using SPSS, the results revealed that the average of mean scores was 3.66 and the average of S.D. was 0.71, with the highest mean score (=4.0) and the lowest score (=3.50), while the highest S.D. was 0.85 and the lowest S.D. was 0.53. Then, by looking closely at how English is taught through games in third-grade classrooms now and finding the problems teachers are having putting it into practice, several major problems become clear. These include teachers' biased views of game-based teaching, teachers' haphazard use of game methods, a lack of variety and newness in game materials, and students who aren't interested enough. Building upon these findings, the research proposes tailored teaching strategies aligned with the learning characteristics of third-grade students and the demands of the English curriculum. These strategies include meticulous preplanning to ensure the suitability of game teaching, providing moderate guidance to enhance student participation and engagement, fostering interactive learning atmospheres through verbal and non-verbal exchanges, and facilitating post-game reflection to stimulate critical thinking and optimize teaching effectiveness.
