  • Homogeneização assintótica de laminados microperiódicos elásticos
           não lineares

    • Authors: Leslie Darien Pérez-Fernández
      Pages: 1 - 21
      Abstract: Estuda-se o comportamento efetivo de laminados microperiódicos elásticos não lineares no regime de deformação finita mediante o método de homogeneização assintótica. Analisam-se vários tipos de comportamento constitutivo via combinações de hiperelasticidade com e sem amolecimento e/ou gradação funcional das lâminas sob diferentes tipos de deformação, inclusive a influência no comportamento efetivo de parâmetros que controlam a gradação funcional, a compressibilidade, e o amolecimento.

  • COVID-19: impactos na mortalidade e expectativa de vida no Brasil em 2020
           e 2021

    • Authors: Raiane de Lima Silva, Alice Silva Duarte, Luísa Pimenta Terra
      Pages: 22 - 35
      Abstract: Since the end of the year 2019, the world has faced a new threat: a virus from the coronavirus family has spread quickly and is characterized as a global health problem. On August 3, 2021, in the world there were already 199,142,755 cases and 4,240,279 deaths caused by COVID-19. Due to lack of preparation, several countries had a slow pace in facing the pandemic, generating social and economic consequences for society. The high number of deaths impacts the population's age structure and, consequently, life expectancy. Therefore, the objective of this study is to analyze the behavior of the COVID-19 pandemic in the age structure of the Brazilian population in 2020, in addition to observing the behavior of new cases and deaths from COVID-19 after the start of vaccination in 2021 for that population. The development of this study took place through the application of the multiple decrements model to estimate life expectancy at birth in a scenario prior to the pandemic (2019) and in a scenario with COVID-19 (year 2020). The data contains information on the number of deaths from COVID-19 and from all causes in addition to the population by age and sex. The results of this study involve changes in the life expectancy of Brazilians after the COVID pandemic and a new behavior in the curve of new cases and deaths from COVID-19 after the start of vaccination.

  • Aplicação dos modelos lineares generalizados na análise de dados da
           brotação e enraizamento de estacas de amoreira coletadas no Planalto Sul
           Catarinense

    • Authors: Daniela Tomazelli, Simone Silmara Werner, Tássio Dresch Rech, Murilo Dalla Costa
      Pages: 36 - 40
      Abstract: A amoreira-negra é uma espécie arbórea de crescimento rápido, com facilidade de adaptação às diferentes condições climáticas do Brasil, sendo uma alternativa de utilização como mourão vivo. O presente trabalho objetivou estudar a aplicação de modelos lineares generalizados na análise dos dados de enraizamento e brotação de estacas de amoreira-negra provenientes de diferentes locais de origem do Planalto Sul Catarinense. Para isso, um experimento foi conduzido em delineamento experimental inteiramente casualizado, sendo os tratamentos constituídos por seis locais de origens do material vegetativo: Araçá- São José do Cerrito; Produtor 1- São José do Cerrito; Produtor 2- São José do Cerrito; Epagri-Lages; Frei Rogério-Lages; e Bocaína do Sul.Cada parcela foi constituída de 10 estacas, sendo utilizadas 4 repetições por tratamento. Após 85 dias de estaquia, avaliou-se o número de estacas enraizadas e o número de estacas com brotos em cada parcela. Para análises dos dados foram considerados os modelos binomial e binomial com parâmetro de dispersão constante. Todas as análises foram realizadas com o auxílio do ambiente R. Em ambos os casos observou-se subdispersão e o modelo com o parâmetro de dispersão constante (quasibinomial) foi o que proporcionou o melhor ajuste.

  • Modelagem e análise da satisfação dos consumidores de uma instituição
           financeira utilizando aprendizado de máquina

    • Authors: Igor Caetano Silva, Ricardo Menezes Salgado
      Pages: 41 - 54
      Abstract: With the market becoming more and more competitive, it becomes necessary to maintain a good relationship with your consumers, a factor that can generate optimization of resources and an immense competitive advantage. Among the markets that depend most on this relationship to keep their customers, make them generate value through word-of-mouth marketing and avoid evasion to competitors are banks and insurance companies. Thus, this article presents a Data Science methodology with the objective of creating a model that can predict the satisfaction of a financial institution’s customers, through its characteristics and behavior described in a database provided by the bank. In a way that allows the company to act with countermeasures to reverse the cases of dissatisfaction. As a proposed solution, three machine learning models were used (Decision Tree, Random Forest and XGBoost) that had a maximum performance of 82.02%, 81.61% and 83.39%, a considerable and efficient performance due the nature of the problem and database.

  • Popularidade de Donald Trump e Barack Obama no Twitter: um estudo de caso
           via análise de cluster

    • Authors: Gabriel Baldasso, Ricardo Menezes Salgado, Eric Batista Ferreira
      Pages: 55 - 66
      Abstract: O avanço da tecnologia e da internet nos últimos anos levou a um aumento massivo no uso das redes sociais. Somente o Twitter de 2019 a 2020 viu seu número de usuários crescer mais de 20%, o que trouxe um aumento significativo no número de publicações. Essas mensagens postadas no Twitter são chamadas de tuítes e têm uma métrica de engajamento medidas por: curtidas, retuítes e respostas. Logo, este artigo busca realizar uma análise de agrupamento dos tuítes dos ex-presidentes: Barack Obama e Donald Trump, com base nas "proporções" entre as métricas: curtidas, respostas e retuítes. Os tuítes dos ex-presidentes foram agrupados em dois e três grupos, usando os algoritmos K-Means e Fuzzy C-Means e comparados com as médias das proporções. De acordo com a análise do K-Means, os resultados dos tuítes de Barack Obama mostraram um grupo com um valor médio alto para a relação retuíte/curtida. No entanto, esses resultados não foram encontrados na análise com Fuzzy C-Means. No agrupamento com os tuítes de Donald Trump, um grupo apresentou uma alta proporção de respostas/retuítes em ambas as análises. Os resultados do algoritmo K-Means são promissores por agrupar tuítes com características populares para a conta de Barack Obama e tuítes polêmicos para as publicações de Donald Trump. Os resultados do algoritmo Fuzzy C-Means diferiram dos resultados do K-Means para os tuítes de Barack Obama. No entanto, para os tuítes de Trump, os dois algoritmos mostraram alta similaridade nos resultados.
