Authors: Xie Wei , Wu Fei , Ouyang Chao , Yang Yan , Qian Jian , Lin Shuang , Zhou Chenxi , Zhang Jun
Published: December 2024

As an important means to ensure the safety of power transmission, the inspection of overhead transmission lines requires high accuracy for detecting small objects on the transmission lines and relies heavily on the construction of large-scale datasets by using deep learning instead of manual inspection. However, transmission inspection data often involve some sensitive information and need to be labeled by professionals, so it is difficult to construct a large transmission inspection dataset. In order to solve the problem of how to effectively train only on a small amount of transmission line data and achieve high object detection accuracy considering the large-scale variation in transmission objects, we propose an enhanced self-supervised pre-training model for DETR-like models, which are innovative object detectors eliminating hand-crafted non-maximum suppression and manual anchor design compared to previous CNN-based detectors. This paper mainly covers the following two points: (i) We compare UP-DETR and DETReg, noting that UP-DETR’s random cropping method performs poorly on small datasets and affects DETR’s localization ability. To address this, we adopt DETReg’s approach, replacing Selective Search with Edge Boxes for better results. (ii) To tackle large-scale variations in transmission inspection datasets, we propose a multi-scale feature reconstruction task, aligning feature embeddings with multi-scale encoder embeddings, and enhancing multi-scale object detection. Our method surpasses UP-DETR DETReg with DETR variants when fine-tuning PASCAL VOC and PTL-AI Furnas for object detection.
Susceptibility of a Multivariate Approach to the Measurement of Neighborhood-Level Socioeconomic Status in Neighborhoods and Health Research: Descriptive Findings with Analytical Reasoning
Authors: Oka Masayoshi
Published: December 2024

A fairly large number of area-based indices have been developed in the United States (US) and other countries to examine the contextual effect of neighborhood-level socioeconomic status (SES) on health. However, two conceptual and methodological review articles raised several concerns about a multivariate approach to the measurement of neighborhood-level SES. To untangle some of the conceptual and methodological concerns raised in those review articles, the purpose of this study was to illuminate a couple of common oversights masked by the lack of analytical transparency in neighborhoods and health research. Using the State of California and its seven Metropolitan Statistical Areas as the study areas, census-tract-level population estimates from the 2000 Census as well as the 2005–2009, 2010–2014, and 2015–2019 American Community Survey were obtained from the United States Census Bureau’s website for conducting a sequence of data analyses. The results of this study suggest that a multivariate approach to the measurement of neighborhood-level SES may be susceptible to the spatial size and spatial configuration of geographic areas and/or the population size and population structure of geographic areas. For these reasons, a few underlying sources of measurement uncertainty, which may undermine the generalizability of existing area-based indices and their measurement validity, are discussed in a general sense so as to be relevant for examining the contextual effect of neighborhood-level SES on health in the US and other countries.
Impact Investing Innovation—From Impact 1.0 to 3.0
Authors: Kaal Wulf
Published: December 2024

Impact innovation has progressed through three phases: 1.0, 2.0, and 3.0. Impact 1.0 introduced carbon credit trading, while Impact 2.0 added participatory grantmaking, impact measurement, and price competitions. Impact 3.0 incorporates Web3 community tools and impact certificate trading. This paper examines the evolution of these phases, focusing on Impact 3.0’s influence on philanthropic practices. Through an analysis of the literature and case studies, Web3 technologies and impact certificate markets are investigated for how these innovations affect transparency and efficiency in social impact initiatives. The information gathered indicates that Impact 3.0 facilitates decentralized impact verification and creates a marketplace aligning stakeholder interests. Consequently, leveraging the features of Web3 technologies can enable philanthropy to scale significantly and provide insights for impact-focused donors aiming to improve outcomes.
PCCDiff: Point Cloud Completion with Conditional Denoising Diffusion Probabilistic Models
Authors: Li Yang , Peng Fanchen , Dou Feng , Xiao Yao , Li Yi
Published: December 2024

Point clouds obtained from laser scanners or other devices often exhibit incompleteness, which poses a challenge for subsequent point cloud processing. Therefore, accurately predicting the complete shape from partial observations has paramount significance. In this paper, we introduce PCCDiff, a probabilistic model inspired by Denoising Diffusion Probabilistic Models (DDPMs), designed for point cloud completion tasks. Our model aims to predict missing parts in incomplete 3D shapes by learning the reverse diffusion process, transforming a 3D Gaussian noise distribution into the desired shape distribution without any structural assumption (e.g., geometric symmetry). Firstly, we design a conditional point cloud completion network that integrates Missing-Transformer and TreeGCN, facilitating the prediction of complete point cloud features. Subsequently, at each step of the diffusion process, the obtained point cloud features serve as condition inputs for the symmetric Diffusion ResUNet. By incorporating these condition features and incomplete point clouds into the diffusion process, PCCDiff demonstrates superior generation performance compared to other methods. Finally, extensive experiments are conducted to demonstrate the effectiveness of our proposed generative model for completing point clouds.
Function and Potential ceRNA Identification of Circ_009773 in Neodymium Oxide Nanoparticle-Induced Lung Epithelial Mesenchymal Transition
Authors: Gao Lei , Juan Juan , Zheng Zimeng , Huang Lihua
Published: December 2024

Nanoparticles of neodymium oxide (NPs-Nd2O3) can induce respiratory-related diseases, including lung tissue injury when entering the organism through the respiratory tract. However, it is currently unclear whether they can induce epithelial–mesenchymal transition (EMT) in lung tissue and the related mechanisms. In this study, we investigated the function of circ_009773 in the process of EMT induced by NPs-Nd2O3 in lung tissue from in vivo as well as in vitro experiments. The findings showed that NPs-Nd2O3 induced EMT in 16HBE cells and SD rat lung tissues. This was characterised by a decrease in epithelial markers and an increase in mesenchymal markers. Additionally, circ_009773 expression was found to decrease in 16HBE cells infected with NPs-Nd2O3 and also decreased in the lung tissues of SD rats. Relevant experiments showed that circ_009773 inhibited EMT in NPs-Nd2O3-treated 16HBE cells and SD rat lung tissues. The previous experiments revealed that circ_009773 was localised in the cytoplasm and functioned at the post-transcriptional level. With the EMT-related pathway used as the basis for circ_009773-related competing endogenous (ce)RNA mechanisms, our observations indicate that circ_009773 is capable of binding to and regulating the expression of miR-135b-5p. In summary, we found that circ_009773 inhibits the EMT induced by NPs-Nd2O3 in lung tissues, and this process likely occurs through competitive binding to miR-135b-5p.
Being a Mother of Two Sons. Duchess Franciszka Urszula Wiśniowiecka-Radziwiłłowa’s Relationship with Her Twin Sons in the Light of Her Correspondence
Authors: Manyś Bernadetta
Published: December 2024

The aim of the article is to deepen the research on the inter-relations within the most influential families and their members in the eighteenth-century Grand Duchy of Lithuania by attempting to look at the relations between mothers and their children, particularly sons, through the prism of ego-documents: by examining the women’s letters written to the spouse, their mother-in-law, and children. The heroine of this article is Franciszka Urszula Radziwiłłowa z Wiśniowieckich, (1705–1753), the spouse of Michał Kazimierz ‘Rybeńko’ Radziwiłł, one of the most influential Lithuanian noblemen of the time. Her literary works and cultural activities have been extensively studied in Polish (less so in Lithuanian) historiography. These studies introduce Franciszka Urszula as a creator, a wealthy matron, and the wife of an influential nobleman. Yet in her letters to her husband, she reveals herself as a very sensitive and loving woman, full of anxiety
and concern for the well-being of her husband and children. The analysis of the duchess’s correspondence of 1734 to 1746 attempted to answer, among others, the following questions: what did the correspondence of the noblewoman reveal about family relations? How did she fulfil her role as a mother? How significantly was she engaged in the upbringing and education of her sons?

THE INFLUENCE OF TEAM MANAGEMENT ON THE INNOVATIVE DEVELOPMENT OF THE ORGANIZATION
Authors: BOLSHAIA O. , BABENKO I. , KUZMENKO H.
Published: December 2024

Team management is an effective tool that not only enhances employee productivity but also stimulates innovation processes within a company. Innovations have become a decisive factor for success in today’s dynamic world, where rapid technological advancements, intensified competition, and increasing customer demands compel companies to be flexible, creative, and adaptive.
Teams formed to accomplish specific tasks significantly boost efficiency in developing and implementing new ideas. They create synergy by combining diverse knowledge, skills, and experiences of their members, fostering creativity and unconventional solutions. Effective team management facilitates horizontal communication, simplifying the exchange of ideas, reducing conflict levels, and strengthening mutual understanding within the group.
However, implementing team management is not without challenges. To ensure a team operates effectively, its composition must be carefully balanced, taking into account professional competencies, personal traits, and work styles. Leadership is another critical success factor – an effective leader must motivate, coordinate actions, and resolve conflicts promptly. Poor leadership can not only diminish the team’s innovation potential but also generate additional internal problems for the organization.
Another essential aspect is creating an environment that fosters innovation. This involves providing necessary resources such as time, technology, and finances, as well as cultivating a culture where every employee feels valued and encouraged to share their ideas. Without proper support from leadership, even the most talented teams may fail to successfully implement innovations.
The study of the impact of team management on an organization's innovative development is crucial for both academic research and managerial practice. It helps to understand how to manage teams effectively to enhance competitiveness and ensure sustainable growth in the face of constant changes in the modern environment.

Published: December 2024

Today, exhibition activity is a relevant field of modern culture, education and development of society. Exhibitions have an important aesthetic, cultural, scientific and philosophical mission. The article reflects the birth of exhibition activity in the world and the work of international organizations in this direction, gives examples of various classifications of exhibitions.
Despite the large number of scientific works on the researched topic, it is worth noting the debatability of approaches to the interpretation of the very concept of "exhibition" and their classifications. It is noted that exhibitions are classified by venue, sources of funding, status, subject matter, etc.
The most common classification in the cultural and educational spheres is the division of exhibitions by direction. It is possible to combine several directions at the same time. For example: educational-scientific, artistic-artistic, scientific-technical. By branch, according to the international classification of exhibitions of the UFI (World Association of the Exhibition Industry), there are two main classes: specialized exhibitions and universal and multi-disciplinary exhibitions.
The article examines the problematic issues of classification of exhibition activity and determines the factors affecting it, analyzes the characteristics of the development and formation of exhibition activity in the world. Prospects and problems related to the development of the exhibition institute in the world are relevant and require in-depth research.
The correct ratio of the topic and the form of the event is the key to the success of a good exhibition. With the development of society, exhibitions also develop.
Exhibitions are a creation of a certain time and place, a reflection of culture, art, education and society at a certain historical moment. The main goal of the exhibition is to tell a new story, create a new context, ensure access and relevance for the modern viewer, which is a constant challenge for the organizers of the exhibition.

Aristotle’s “Organon”: From the Incunabulum in the Brukenthal Museum Library to the Syriac Commentaries of Sergius of Resh’ayna
Authors:   Faculty of Theology, „Lucian Blaga” University, Sibiu, Ittu Constantin
Published: December 2024

The present paper aims at introducing one of the incu-nabulum from Brukenthal National Museum Library, i.e., Aristotle´s Organon, published in Venice by Baptista de Tordis in 1484. From this perspective, Venice had become the leading centre of book production outside Germany in the fifteenth century, in other words, in the very century of incunabula publication. On the one hand, the work of Syriac scholars in translating and commenting upon Aristotle has been acknowledged as the starting point of the later Arabic-Latin build out. On the other hand, Sergius of Resh´ayna, the author of two related Syriac commentaries on Aristotle´s Categories, was planning to write commentaries on all of Aristotle texts but he seemed to have written nothing beside the Categories before he was overtaken by illness in Constantinople, where he passed away in 536.

Published: December 2024

In any translation, several levels are assumed to mutually intertwine, in order to achieve optimal communication: on the one hand, a general level, abstract and impersonal, in which grammar (morphology and syntax) and lexicon are incorporated, on the other hand, a particular level, of concrete action, in which, first of all, stylistics and pragmatics are manifested, having a given statement at its core of attention. The texts collected in the Parliamentary Annals of Romania offer an extremely rich and interesting material that sheds light not only on the history of the Romanian language, but also on the complexity of translation, which involves a journey from the abstract to the concrete, from language to communication, from word to text. The present work focuses on lexical aspects (neologisms, the cliché phenomenon, the re-semantization) on which a functional style, i.e. a certain genre of discourse in the Bakhtinian sense, is gradually built.

During the Second World War, and especially during the years when Northern Transylvania was part of Hungary, Bishop Iuliu Hossu was a protector of reading practices and other cultural activities, providing constant support and promoting cultural events among the priests. Both the clergy and part of the laity belonging to the Greek-Catholic Diocese of Cluj-Gherla, stimulated by the efforts of Iuliu Hossu, donated a significant number of books in Romanian to libraries, at a time when the government of Budapest tried to restrict the language. In those difficult conditions, books and newspapers written in Romanian ended up being mainly kept in the libraries that were under the auspices of the diocese.

Aiming to recuperate a literary history truth, concerning the first true integral Romanian version of The Book of the Thousand and One Nights, the article’s author reconstructs the avatar of printing this great work of universal literature, during the 60s in Romania. For this, he uses unpublished correspondence with the translator himself, philosopher and writer Peter Hossu (1922–1998), the data here being confirmed by the testimonies of the two published memorial works describing the avatar of the version (authors Petre Hossu and Andrei-Iustin Hossu). Although, after two attempts to print (1966, Editura Pentru Literatură; 1991–1996, Editura Saeculum,3 volumes), this first full translation into Romanian of the Book of the Thousand and One Nights, done by Petre Hossu during 1960–1963, remained mostly in manuscript stage, because there is a cultural rapt, only the first volume being published under his name. The “canonical” version of Haralambie Grămescu is a later one, made, by his own confession, during 27 years (1966–1993).
Caracterização físico-química e avaliação da citocompatibidade do nanobiocompósito de quitosana e nanofibra de celulose em fibroblastos e queratinócitos humanos cultivados in vitro

Published: December 2024

A pele possui um mecanismo natural de autorreparo em caso de lesões, contudo, em alguns casos, o processo de cicatrização pode ser comprometido, requerendo cuidados para auxiliar a reparação do órgão. Terapias reparativas têm sido objeto de estudos para o tratamento de lesões e os biopolímeros quitosana e nanofibra de celulose (NFC) se destacam por apresentarem propriedades biodegradáveis, antimicrobianas e características mecânicas semelhantes à da matriz extracelular natural. No entanto, até o momento, não há relatos sobre o uso combinado da quitosana e NFC extraídas do algodão na produção de um nanobiocompósito para aplicação na medicina reparativa da pele. Assim, o objetivo desse estudo foi realizar a caracterização físico-químico e avaliar a citocompatibilidade do nanobiocompósito de quitosana e NFC de algodão em fibroblastos e queratinócitos humanos cultivados in vitro. Inicialmente, foram realizadas avaliações de homogeneidade, estabilidade, rugosidade, porosidade e propriedades mecânicas do nanobiocompósitos. Posteriormente, foram realizados os ensaios in vitro de microscopia de luz, citometria de fluxo, MTT, Alamar Blue, cicatrização e produção de colágeno. Os resultados demonstraram que a incorporação da NFC ao filme de quitosana, formando um nanobiocompósito, resultou em um filme com melhores características como taxa de degradação, intumescimento, hidrofilicidade e rugosidade, otimizando sua aplicação na realização de testes in vitro. A viabilidade celular, cicatrização e produção de colágeno por fibroblastos e queratinócitos humanos indicam a citocompatibilidade do nanobiocomposito em cultura in vitro. Baseado nos resultados, o nanobiocompósito de quitosana com NFC apresenta potencial para aplicação futura em terapias reparativas para o tratamento de lesão na pele, bem como um modelo de teste de dermocosméticos.
Os entrelugares da religião: teoria e epistemologia a partir de Mark C. Taylor
Authors:   , Vasconcellos Danilo Souza Mendes de
Published: December 2024

Esta tese diz respeito a como a teoria da religião implica novos modos de estudar a religião, a partir de Mark C. Taylor. Primeiramente, delineamos as lógicas internas de sua obra, apresentando como ele recepciona o pensamento da desconstrução na teologia e desenvolve uma lógica não binária de pensamento, fugindo às opções monistas e dualistas de relação. Em segundo lugar, demonstramos a teoria da religião de Taylor verificando como ela se conjuga com a obra do autor. Sua principal tese é de que a religião é mais interessante nos lugares em que ela é menos óbvia. Nesse ponto, avaliamos se sua proposta teórica, que articula desconstrução e complexidade, é adequada aos desafios que a religião na contemporaneidade nos impõe. Na terceira parte, uma encruzilhada. Fazemos um interlúdio, uma pausa para refletir, de um ponto de vista decolonial, sobre as escolhas e os silêncios culturais de Taylor. Aqui, propomos um exercício de aproximação entre teoria decolonial e religião afro-brasileira, apresentando alternativas ao pensamento eurocentrado. Em quarto lugar, verificamos as implicações epistemológicas da teoria da religião proposta por Taylor. Para tal, não pensamos somente nas análises culturais que o autor faz, mas no modo como ele as faz, o que chamamos de anarqueologia da religião. A partir dela, propomos novos caminhos para a ciência da religião no Brasil em nível epistemológico e institucional. Por fim, dedicamos o poslúdio a um exercício anarqueológico da religião sobre a tela A Bird Called Innocence de Samuel de Saboia, apresentando como o autor constrói um mundo amável diante de perdas irreparáveis.
A força da fraqueza: sofrimento e despojamento nas trajetórias espirituais de Simone Weil e Henri Nouwen
Authors:   , Costa Karen Aquino Rangel da
Published: December 2024

As trajetórias espirituais de Simone Weil e Henri Nouwen demonstram de forma expressiva a força das experiências espiritual e mística em seus percursos biográficos. Sendo essas dimensões significativas para o estudo da religião, esta tese propõe-se a contribuir com as discussões no campo da espiritualidade e da mística, apresentando a partir de pesquisa bibliográfica uma análise das trajetórias espirituais da filósofa francesa e do teólogo holandês. Com base na investigação de seus percursos biográficos, ou seja, na observação de experiências vividas e das reflexões oriundas das mesmas, apresentam-se dois aspectos fundamentais de uma espiritualidade em movimento: o existencial, que diz respeito à busca humana por sentido, e o místico, que envolve a espera por um contato com o transcendente. Como expressão dessa busca e espera, evidenciam-se na narrativa dos autores os encontros consigo mesmo, com o outro e com Deus. A partir da análise dos mesmos, conservadas as diferenças entre os autores, bem como as particularidades do contexto de cada um deles, assume-se que a consciência da miserabilidade humana e a compreensão da fraqueza como força, é o que os aproxima. Partindo dessa premissa, destacam-se dois elementos centrais em suas trajetórias espirituais: o sofrimento e o despojamento. A hipótese que orientou a pesquisa, de que nelas o despojamento surge como resposta ao sofrimento e que, por meio deste, Weil e Nouwen foram conduzidos à experiência de Deus, revelou-se parcialmente verdadeira, tendo em vista que essa afirmação não abarca a complexidade da relação entre sofrimento e despojamento identificada ao longo da investigação. Assim, através dos dados encontrados, delineia-se uma reflexão acerca das trajetórias espirituais de Simone Weil e Henri Nouwen, buscando demonstrar a relação de complementaridade entre sofrimento e despojamento, tal como compreendida e vivida por eles no contexto de suas experiências espirituais e místicas. A compaixão, como fruto dessa relação, configura-se como traço distintivo do compromisso mais profundo de suas vidas.

Teve-se como objetivo criar modelos educomunicativos musicais para o ensino de música no espaço escolar público: um Possível e um Desejável. A pesquisa, além de ser bibliográfica, envolveu também a aplicação de questionários e a realização de entrevistas com professores de música da rede municipal de ensino de Juiz de Fora, caracterizandose como uma pesquisa qualitativa e exploratória. Os dados da pesquisa empírica, conjuntamente com a teoria, contribuíram para a proposição dos modelos educomunicativos musicais. O Modelo Educomunicativo Musical Possível no Espaço Escolar Público Atual considera que a comunicação do ensino da música precisa passar por um olhar sensível na compreensão e discussão das dificuldades de legitimação da música, da falta de recursos tecnológicos e informacionais, da falta de espaço físico adequado, da não disponibilidade de instrumentos musicais existentes na cultura musical popular e/ou erudito que não pode ser comprado pela escola pública. O professor precisa ser um multi-instrumentista para ser um facilitador da alfabetização musical da linguagem musical e da alfabetização tecnológica e informacional através dos instrumentos possíveis existentes na escola. Já o Modelo Educomunicativo Musical Desejável no Espaço Escolar Público é um modelo onde se idealiza uma escola pública em que a comunicação da educação musical está interligada com os vários campos da tecnologia midiática e informacional. As relações educomunicativas de aprendizagens possibilitam experimentar vários instrumentos musicais com diferentes professores especialistas em instrumentos específicos, dentro de uma mesma escola e, preparados para intercalar a tecnologia a esse instrumento específico. O professor será um facilitador da alfabetização musical da linguagem musical e da alfabetização tecnológica e informacional para uma escolha específica de um instrumento musical pelo aluno. Os dois modelos colaboram com a promoção de um campo crítico para a comunicação do ensino de música através de práticas educomunicativas musicais no espaço escolar público. Ao mesmo tempo, trazem contribuições consideráveis elencando as diferenças de como a música pode ser vivenciada pelos seus pares dentro desse espaço, trazendo à tona o questionamento de qual tipo de sujeito a escola pública quer ou tem formado através da música.

A construção de um modelo confiável é um dos pilares do controle de sistemas autônomos. A identificação é um processo que extrai características de um processo para posterior análise e manipulação do sistema. Modelos matemáticos são um direcionamento do comportamento real de um processo. Entretanto, tais modelos exigem a entrada de alguns parâmetros específicos da operação do sistema. A estimação de parâmetros, é uma forma de identificação que objetiva afinar modelos para que eles se comportem de forma próxima à realidade. Para tanto, utiliza-se métodos de estimação, que aliados a um sinal de entrada eficiente, podem produzir bons resultados. O Sub-Optimal Excitation Signal Generation and Optimal Parameter Estimation (SOESGOPE) é um método apresentado pela literatura que combina a geração de sinais de excitação com a estimação de parâmetros. Embora a metodologia apresente resultados satisfatórios, deve-se analisá-la sob o ponto de vista de otimização, ou seja o quanto ele é confiável e robusto frente a diferentes configurações. Assim, este trabalho apresenta análises nesse aspecto e uma proposta de alteração quando for verificado uma falta de convergência. A aplicabilidade do método é potencializada em situações em que o modelo seja uma cópia razoável do comportamento real. Entretanto, em situações reais, não se pode garantir que um modelo matemático produza saídas similares ao processo real frente a uma mesma entrada. Para contornar esse problema, neste trabalho também é proposta uma técnica híbrida que é capaz de utilizar o modelo matemático como direcionamento e aprender características peculiares àquele processo. Tal modelo híbrido, composto por etapa de estimação e de aprendizado de comportamento, será capaz de corrigir certos erros do sistema real relacionados ao modelo e atingir saídas mais confiáveis através da combinação do modelo teórico com técnicas de aprendizado. Além disso, o SOESGOPE é um aliado ao processo de aprendizado visto que fornece sinais de excitação mais eficientes. A eficácia do método é comprovada através da aplicação em uma embarcação autônoma com características desafiadoras sob a ótica de identificação, reduzindo o erro de estimação de trajetória.

A aplicação de técnicas computacionais, processamento de sinais e extração de características à interrogação de sensores ópticos baseados em grades de período longo é objeto de intenso desenvolvimento de pesquisa recente e ainda demanda aprofundamento. Considerando a aplicação cada vez mais ampla de sensores a fibra óptica, este trabalho visa apresentar formas alternativas de interrogação que não dependam da análise espectral ou de equipamentos de alto custo. Duas propostas são apresentadas. A primeira é baseada na separação do sinal do sensor em sub-bandas espectrais e posterior análise da potência óptica de cada sub-banda por uma rede neural artificial. A segunda proposta é baseada na extração de características aplicada a traços de reflectometria medidos em fibras contendo grades de período longo e na utilização de descritores de características como variáveis explicativas em um algoritmo de regressão linear múltipla. Ambas as propostas se valem de métodos computacionais para atingir o objetivo de recuperar a informação coletada pelo sensor e fornecê-la em um formato adequado. Os resultados obtidos indicam que os métodos propostos, com configurações experimentais simples, apresentam desempenhos melhores que os de métodos similares, ou apresentam desempenho comparável adicionando as vantagens inerentes ao sensoriamento a fibra.

Este documento apresenta a tese de doutorado que tem como objetivo aportar contribuições na área de transmissores para comunicação por luz visível (VLC), propondo drivers de LED alimentados a partir da rede elétrica CA com interruptor único, que tenham dupla funcionalidade: iluminação e transmissão de dados. O trabalho apresenta alternativas que buscam atender à gama de aplicações que requerem baixa taxa de transmissão de dados utilizando modulação baseada em FSK (do inglês, Frequencyshift keying). A primeira alternativa de transmissor VLC é baseada em um circuito de correção de fator de potência (PFC) flyback operando em modo de condução descontínua (DCM). A regulação da corrente média de saída e a modulação dos dados são alcançadas simultaneamente pela modulação do sinal PWM (do inglês, Pulse-width modulation), que aciona o interruptor do conversor flyback. Para que seja possível a transmissão de dados, um filtro rejeita-faixa de terceira ordem e uma malha de controle antecipatória (feedforward) foram utilizados. Esta estratégia mantém a simplicidade da topologia convencional enquanto habilita a funcionalidade de transmissor VLC com um número reduzido de componentes. Resultados experimentais foram obtidos de um protótipo de 14 W, alimentado a partir da rede elétrica de 127-V 60-Hz, para verificar a viabilidade e o desempenho do transmissor VLC, por meio do qual foi possível transmitir dados a uma taxa de dados de 15 kb/s para uma distância de até 2 m com uma eficiência global de 93,3%. Em seguida, foi efetuado um estudo de desempenho do sistema VLC para três diferentes tipos de formas de ondas, no qual foi possível verificar que a onda quadrada apresenta menor susceptibilidade a interferências. Assim, a segunda alternativa de transmissor VLC consiste da topologia buck-boost flyback integrada. Nesta estrutura o estágio PFC opera em DCM para manter elevado fator de potência, e o estágio PC não possui capacitor na saída e opera em modo de condução contínua (CCM), que possibilita forma de onda quadrada na corrente dos LEDs sem a inserção de um interruptor adicional. Resultados experimentais foram obtidos para um protótipo de 35 W, alimentado a partir de uma entrada universal (90 a 264-V 60 Hz), para verificar o funcionamento em toda a faixa de operação e o desempenho do transmissor VLC na condição nominal de tensão de entrada. Foi verificado que é possível transmitir dados com taxa de até 248 kb/s para uma distância de até 3 m com eficiência global de no máximo 82,7%. Por fim, são discutidas as principais contribuições da tese e algumas propostas para trabalhos futuros são apresentadas.
