Resumo: The Internet of Things (IoT) and fifth-generation mobile networks (5G) represent two of the most transformative technologies of the 21st century. When integrated, they offer a synergistic foundation for advanced applications in numerous fields, from healthcare to transportation, agriculture, industry, and smart urban infrastructure. IoT enables devices to sense, transmit, and act on data autonomously, while 5G provides the ultra-fast, ultra-reliable, and high-capacity network environment these devices require to function at scale. The confluence of these technologies is driving the emergence of interconnected ecosystems that are reshaping business models, service delivery, and public life. This paper explores the impact of 5G on IoT, assesses their combined influence on society, and discusses both the technological advantages and the risks—particularly in terms of security, privacy, and ethical concerns. Through an in-depth examination of their architectures, capabilities, limitations, and real-world deployments, we conclude that the integration of 5G and IoT holds tremendous potential to revolutionize daily life, but achieving this promise will depend on addressing foundational challenges in regulation, trust, and inclusivity. We evaluate how 5G and IoT together are redefining the digital landscape, while also identifying key challenges that must be addressed for their widespread and sustainable adoption.2025-01-01T00:00:00ZFrom info-exclusion risk to civic participation: The perception of digital citizenship among poor peopleHaddad, S.

Resumo: In Brazil, even after 21 years of implementing digital inclusion policies, there are still few valid dimensions and indicators to develop statistical models to assess the effectiveness of these policies in terms of the exercise of citizenship, as a way of contributing to the reduction of infoexclusion in a global context of rising poverty levels in recent decades. The present study explores the meaning and the importance of citizenship for the poor through a questionnaire answered by 515 users from 84 telecenters in Belo Horizonte, Brazil. Using Principal Component Analysis (PCA), three dimesions with 31 indicators were obtained for citizenship and three dimensions with 33 indicators for digital citizenship. Assessed in the context of today's society, these dimensions proved to be complementary and inseparable for the effective exercise of citizenship. Thus, the results of this study contribute to the improvement of public policies for digital inclusion and prevention of poverty.; No Brasil, mesmo após 21 anos de implementação das políticas de inclusão digital, ainda há escassez de dimensões e indicadores para a construção de modelos estatísticos que avaliem a eficácia destas políticas no que tange o exercício da cidadania, como forma de contribuir para a redução da infoexclusão num contexto global de aumento dos níveis de pobreza nas últimas décadas. O presente estudo explora o significado e a importância da cidadania para os pobres por meio de questionário respondido por 515 utilizadores de 84 telecentros em Belo Horizonte, Brasil. Utilizando-se Análise de Componentes Principais (ACP), obtiveram-se três dimensões para cidadania com 31 indicadores e três dimensões para cidadania digital com 33 indicadores. Avaliadas no contexto da sociedade atual, tais dimensões se mostraram complementares e indissociáveis para o efetivo exercício da cidadania. Assim, os resultados deste estudo contribuem para o aperfeiçoamento de políticas públicas de inclusão digital e combate à pobreza.2023-01-01T00:00:00ZM|G|∞ queue heavy-traffic situation busy period length distribution (power and Pareto service distributions)Ferreira, M.

Autoria: Ferreira, M. A. M.
Resumo: (Ferreira e Ramalhoto, 1994) mostraram que para distribuições de serviço tais que lim G(t) = 0 (G(.) é a função de distribuição e a a média), para a e r (intensidade de tráfego) suficientemente grandes a distribuição do comprimento do período de ocupação da fila de espera M|G|∞ é aproximadamente exponencial. Neste trabalho mostramos que para distribuições de serviço para as quais aquela condição não se verifica necessariamente, é possível em certas situações ter um comportamento aproximadamente exponencial para o comprimento do período de ocupação da fila de espera M|G|∞.2001-01-01T00:00:00ZMean number of the customers served during a busy period in the M|G|∞ queueing systemFerreira, M.

Autoria: Ferreira, M. A. M.
Resumo: We deduce an exact expression that gives the mean number of the customers served during a busy period in the M|M|∞ queueing system and conjecture an upper bound of this quantity for other M|G|∞ systems, with service times not exponential, based on the results of a Markov Renewal Process.2001-01-01T00:00:00Z
