J. de. Resumo: The intersection of biology and architecture has become increasingly relevant in the context of sustainability, technological integration, and the search for adaptive and intelligent systems within the built environment. Biomimetics offers a powerful framework for translating the functions and processes of natural organisms into design solutions that can enhance architectural performance (Benyus, 1997). However, while formal analogies with nature have been well explored, there remains a gap in applying biological regulatory systems—such as genetic networks—as direct models for spatial and behavioural design. This article addresses that gap by examining Musical Morphogenesis, a biomimetic and interactive installation developed between 2014 and 2017. The project is centred on the gene regulatory network of Arabidopsis thaliana, a well-studied model organism in plant biology (Meyerowitz, 1997). The research investigates how computational simulations of gene activation patterns can inform the development of kinetic architectural systems capable of self-organization, responsiveness, and expressive interaction. The primary aim of this research is to explore how architectural elements can embody the logic of genetic development, transforming molecular pathways into motion, light, and sound. The study is driven by the question: How can gene regulatory networks be translated into performative, interactive spatial systems that reflect biological complexity? To answer this, the project integrates a Boolean logic-based gene model into a physical structure composed of CNC-fabricated components, pneumatic actuators, LED lighting, and an interactive touchscreen interface. The methodology involves interdisciplinary collaboration across architecture, computational biology, engineering, and music composition, resulting in a system where user interactions can influence developmental pathways and trigger morphological changes in real time. The key contribution of this work lies in its demonstration that biological computation can serve not only as inspiration but as a functional blueprint for architectural design. By making genetic dynamics tangible and interactive, Musical Morphogenesis presents a novel approach to biomimetic design that bridges scientific modelling and spatial expression within the broader framework of biodigital architecture.

D.; Reis, J. P. 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.

R.; Oliveira, A.; Alturas, B. 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.

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|∞.
