Item Predição do consumo energético de dispositivos LoRa usando aprendizagem de máquina(2024-12-10) Pimentel, Henrique Pablo Pinheiro dos Santos; Araújo, Danilo Ricardo Barbosa de; http://lattes.cnpq.br/2708354422178489; http://lattes.cnpq.br/0078523045227122A Internet das Coisas (IoT) é um conceito em constante evolução que tem conquistado destaque tanto na comunidade acadêmica quanto na indústria. Dentro dela, o consumo energético é um fator fundamental para determinar o tempo de funcionamento dos dispositivos e a frequência necessária para realizar a manutenção deles. Este artigo investiga a aplicação de algoritmos de aprendizado de máquina para predição do consumo energético de dispositivos IoT-LoRa, permitindo estimar a duração da bateria dos dispositivos e sua autonomia. A metodologia considerou a criação de um conjunto de dados a partir de experimentos com placas de desenvolvimento Event stream processing (ESP32), capturando métricas como tempo de hibernação, tipo de conexão e consumo energético. Técnicas de Inteligência Artificial (IA) são então aplicadas para prever o consumo energético com base nessas variáveis. De acordo com os resultados obtidos, a melhor técnica para prever o consumo energético é a Decision Tree, com um coeficiente de determinação superior a 96%. O estudo contribui para processos decisórios que visam selecionar dispositivos IoT considerando a autonomia projetada para as baterias de tais dispositivos.Item CIMut: ferramenta de injeção de falhas em ambientes de nuvens por mutação(2025-02-13) Duarte, Guilherme Silva; Sousa, Erica Teixeira Gomes de; http://lattes.cnpq.br/9899077867723655; http://lattes.cnpq.br/6937961051628049A injeção de falhas de software é uma técnica valiosa para avaliar a resiliência de sistemas de software complexos. Ao introduzir falhas em componentes específicos, os pesquisadores podem observar como essas falhas se propagam e impactam o comportamento geral do sistema. Este artigo apresenta a ferramenta CIMut, desenvolvida para injeção de falhas por meio da mutação do código-fonte. A mutação do código-fonte possibilita a introdução de falhas para análise de sistemas. Um estudo experimental abrangente realizado no OpenStack, uma plataforma de computação em nuvem de código aberto, demonstra a eficácia da ferramenta. Foram realizados mais de 62 experimentos no OpenStack, cada um injetando falhas em diferentes componentes do sistema. Os resultados do estudo foram promissores. Uma parcela significativa (até 96,7%) das falhas injetadas resultou em bugs, classificados como erros explícitos (travamentos, exceções) ou bugs com impacto funcional (comportamento incorreto, perda de dados). Esses resultados demonstram que a ferramenta CIMut é capaz de gerar falhas representativas que podem ser utilizadas para avaliar a resiliência de sistemas de software complexos como o OpenStack.Item Inteligência artificial no ensino fundamental com robótica lego, aprendizagem baseada em projetos e gamificação(2024) Souza, Diogo Albuquerque Dias de; Rodrigues, Rodrigo Lins; http://lattes.cnpq.br/5512849006877767; http://lattes.cnpq.br/3374743431217595Item Manutenção e preservação de jogos eletrônicos no Brasil: estudo de casos e exemplos(2024-10-04) Tomazini, Renan; Cardoso Junior, Marcos Jose de Menezes; http://lattes.cnpq.br/1172610632435625; http://lattes.cnpq.br/1738058069065754This research aims to explore the history and preservation of electronic games in Brazil, focusing on their sociocultural relevance and the technological challenges of maintaining this medium. Using a case study methodology, the work applies digital preservation principles, based on archival frameworks, to assess the current state of game artifact preservation in Brazil. The study identifies the key initiatives and challenges facing digital game preservation in the country, emphasizing the need for a more robust archival infrastructure. Conclusions highlight the importance of preserving not only the physical and intellectual aspects of digital games but also ensuring their playability, following Huizinga's concept that "a game only exists when played." The research underscores the role of institutions like Bojogá in preserving the interactive experiences that define video games as a cultural and historical medium.Item Análise do ensino de computação nas escolas das cidades Camaragibe e São Lourenço da Mata da GRE Metro Sul - PE(2024-10-03) Oliveira, Públio do Nascimento; França, Rozelma Soares de; http://lattes.cnpq.br/4282789732521235; http://lattes.cnpq.br/4253184080147942The National Common Curricular Base (BNCC) is a fundamental document for education in Brazil, as it establishes competencies and skills that all students must develop during their school career. The Ministry of Education (MEC) approved the standards that define the teaching of computing in basic education in Brazil as a complement to the BNCC. This article analyzes the process of implementing Computing teaching in the state education network of the cities of Camaragibe and São Lourenço da Mata. As main results, it identified that 63% of schools still do not teach Computing, and the challenges cited relate to infrastructure, connectivity and lack of qualified teachers in the area.Item Um recurso didático de computação para crianças baseado no estilo de aprendizagem(2024) Ramos, Cláudia Eduarda de Moura; França, Rozelma Soares de; http://lattes.cnpq.br/4282789732521235; http://lattes.cnpq.br/8195842608999569Item Explorando o pensamento computacional nos anos iniciais do ensino fundamental a partir de soluções criativas para alagamentos na cidade de Recife/PE(2024-03-01) Aureliano, Paulo Vinícius Cabral; França, Rozelma Soares de; http://lattes.cnpq.br/4282789732521235; http://lattes.cnpq.br/3335740440479045This paper proposes a didactic sequence for the development of Computational Thinking (CT) in the 1st year of Elementary School, using the problem of floods in the city of Recife/PE as a learning context. Based on discussions about the reality of CT development in Brazilian schools and the training of teachers working in the field, as well as on the axes and abilities related to computing education in Elementary School present in the complement of Computing to the National Common Curricular Base (BNCC), the objective is to introduce CT concepts in an unplugged way, focusing on key concepts and on the resolution of real problems, especially those related to social issues such as floods. The problem-based methodology will be employed to promote students' autonomy in constructing knowledge, allowing them to use Computing as a tool to address relevant and meaningful issues in their community. This approach aims not only to develop technical skills but also to promote meaningful learning by connecting computational concepts with real and social challenges faced by students. The proposal thus seeks to overcome challenges related to teaching materials and strategies for the effective integration of computing into the curriculum, offering an accessible and socially relevant alternative for computing education in Brazilian schools.Item O impacto da nova matriz curricular da Licenciatura em Computação no desempenho dos discentes(2024-02-16) Silva, Laura Gabrielle de Lira; Falcão, Taciana Pontual da Rocha; http://lattes.cnpq.br/5706959249737319; http://lattes.cnpq.br/5607530930536079Item Analisando o Backup-as-a-Service como uma estratégia de recuperação de desastres(2021-06-02) Queiroz, Ewerton Cleyton Silva de; Andrade, Ermeson Carneiro de; Mendonça Neto, Júlio Rodrigues de; http://lattes.cnpq.br/7849727159222731; http://lattes.cnpq.br/2466077615273972; http://lattes.cnpq.br/1234353605805269In modern environments, failures in information and communication technology (ICT) systems can have several consequences for a business, like data and revenue loss and customers dissatisfaction. Disaster recovery (DR) solutions, as BackupasaService (BaaS), has been adopted by companies as a way to avoid these problems and assure business continuity. Nevertheless, there are plenty of variables to consider during the adoption of a DR solution. Then, in this work, we present an integrated approach using experiments and models to evaluate a BaaS environment designed for DR. In our analysis, we consider relevant DR metrics like availability, downtime, RTO (Recovery Time Objective), and RPO (Recovery Point Objective). The results demonstrate that once BaaS is applied, the environment availability can vary according to the amount of data needed to be backed up or restored. Furthermore, sensitivity analysis indicates that the time needed to recover the data center and the backup interval are the most important parameter values for metrics like RTO and RPO. The proposed approach can help companies or individuals involved in the decisionmaking process for purchasing a DR solution.Item Como a tecnologia assistiva tem contribuído para a inclusão educacional no nordeste? um mapeamento sistemático da literatura(2023-12-21) Carmo, Vinicius José Gonçalves do; França, Rozelma Soares deInclusive education aims to ensure the participation of all students within the school environment. However, various obstacles, such as the lack of preparedness within educational institutions and teachers to address the specificities of people with disabilities, can hinder the realization of this inclusion. In this context, Assistive Technology (AT) emerges as an innovative field, offering resources to promote the inclusion and autonomy of individuals with diverse abilities and needs. The goal of AT is to remove barriers and facilitate access to a more independent life, providing equal opportunities for people with different abilities. This study aimed to investigate the role of AT in promoting educational inclusion in the Northeast region. To achieve this, a systematic literature review was conducted, seeking scientific works published between 2013 and 2023 on platforms such as Google Scholar, Portal de Periódicos CAPES, Revista Novas Tecnologias na Educação (RENOTE), SBC-OpenLib (SOL), Scientific Electronic Library Online (Scielo) e Conferência Internacional sobre Informática na Educação (TISE). Inclusion and exclusion criteria were established to evaluate the retrieved works, resulting in the inclusion of 32 studies. The findings revealed that, during the considered period, the state of Paraíba was the most active in conducting research using AT to promote educational inclusion. Furthermore, it was found that visual impairment was the most explored type in the studies, and software development was the most explored solution. These findings not only highlight the application of AT as a fundamental resource in promoting educational inclusion but also underscore the need for broader and diversified utilization of AT to address the varied needs of students with disabilities, aiming for a more effective and comprehensive inclusion.
