- BIP on fire models in structuresPublication . Papurello, Davide; Stankiuviené, Auara; Hozjan, Toma; Peenko, Robert; Hu, Sabina; Both, Ioan; Fonseca, Elza M.M.; Campos, Armando J. Vilaça; Rego, Rui F. N. de Araújo; Fonseca, Elza M.M.; Campos, Armando J. Vilaça; Rego, Rui F. N. de AraújoThe transition toward sustainable mobility with battery electric vehicles (BEVs) and hydrogen fuel cell vehicles (FCEVs) introduces new fire safety challenges in tunnels. This study examines the behaviour of these technologies under critical conditions and their implications for tunnel risk management. Experimental investigations at the Polytechnic of Turin analysed lithium-ion cells (INR18650 M29 and INR21700-50E, both NMC-based) subjected to mechanical, thermal, and electrical abuse. Nail penetration tests revealed thermal runaway events with peak temperatures between 6003750 °C and pressure stabilisation within minutes, while overheating experiments demonstrated temporary stabilisation by safety valve activation before escalation. External short-circuit tests did not trigger runaway, but significant energy release was observed. Gas analysis indicated hazardous emissions, including HF, CO, and CO¢, with concentrations rising alongside initial temperature, confirming the toxicity of BEV fires in confined spaces. Fire suppression is further complicated by prolonged burning, high water demand, and rapid smoke accumulation. For hydrogen vehicles, the study highlights risks associated with compressed storage (up to 1000 bar), including jet flames, tank ruptures, vapour cloud explosions, and BLEVE events. Safety devices such as thermally activated pressure relief devices (TPRDs) mitigate catastrophic rupture but result in full tank venting, producing intense flames. Event-tree analyses show that even minor leaks can escalate into largescale incidents in confined environments. Current tunnel regulations, designed around conventional vehicles, inadequately address these hazards. The findings stress the urgency of adapting ventilation strategies, detection systems, and suppression technologies, as well as integrating probabilistic risk models that capture thermal runaway dynamics and hydrogen release behaviour. This technical evidence provides a foundation for revising international safety standards and ensuring resilient tunnel infrastructure in the era of alternative propulsion.

- Perceptions of Mechanical Engineering Students Regarding Flipped Laboratory ActivitiesPublication . Duarte, Marina Isabel Felizardo Correia; Monteiro, Maria de Fátima CoelhoLearning in the laboratory is essential in engineering education, but the massification of higher education makes it difficult. Educational technology has opened new possibilities and current trends comprise active methodologies supported by information communication technology, like the flipped pedagogical model. In a mechanical engineering programme in Portugal, curricular changes eliminated all laboratory classes on fluids and heat. To address the need for a hands-on component, optional flipped laboratory activities in thermodynamics were made available to the students. Because these activities require specific resources, like procedures without which they cannot be carried out, this action research aims to evaluate the feasibility of using the flipped approach for their implementation and to identify the type of resources that students perceive as most useful. Thirty-one students attended the activities, which proved to be feasible and which they perceived as contributing to their learning, despite interest being low, and decreasing throughout the semester. The evaluation by the students at the end of each laboratory session proved to be appropriate to the action research methodology. As for the resources, the written procedure is an essential element for laboratory activities and video is a good complement, but it does not replace it.
- Planeamento e contolo da produção: uma visão integradaPublication . Ávila, Paulo; Bastos, João; Cavaco, IsmaelEste livro é o resultado do arranjo e compilação de textos didáticos produzidos ou adaptados pelos seus autores para apoio a unidades curriculares dos mestrados em Engenharia Mecânica - Gestão Industrial e Engenharia Eletrotécnica e Computadores – Sistemas de Planeamento Industrial, do Instituto Superior de Engenharia do Politécnico do Porto. Esses textos foram revistos e reorganizados, com vista, não só a manterem a função original de ajuda à formação de estudantes afetos a esta área do conhecimento, como também a constituírem uma referência de conhecimentos para quem deseje iniciar-se nestes temas; procuram ainda ser uma base de consulta e informação para engenheiros ou outros profissionais com funções na gestão da produção. O livro percorre os marcos mais significativos da trajetória histórica da gestão da produção, com particular foco no planeamento e controlo da produção, procurando interpretar e tornar compreensível a sua evolução, e relevando, sempre que oportuno, a influência da tecnologia nos modelos de gestão, e sua interligação. Começa por uma referência à tipologia dos sistemas de produção no capítulo I e aborda, no capítulo II, as principais funções do planeamento, programação e controlo da produção em contexto MRP, normalmente considerada uma visão mais clássica do tema. Outras duas aproximações com expressividade, a Teoria das Restrições e o JIT/Lean, são abordadas nos capítulos III e IV respetivamente. No capítulo V, o livro finaliza o seu conteúdo com uma breve referência a sistemas de informação empresariais, particularmente vocacionados para contextos de produção. Os autores expressam o seu agradecimento a todos os colegas, alunos e editor, que, com os seus contributos, permitiram chegar ao documento que agora disponibilizamos. Esperamos que lhe seja útil, prezado leitor, que suscite em si a mesma satisfação que o seu longo processo de compilação nos proporcionou, e que possa vir a ser, em próxima revisão, enriquecido com as valiosas críticas, sempre bem-vindas, que haja por bem dedicar-lhe.

- Quality assessment in the manufacture of a pressure piping by weldingPublication . Pereira, A. B.; Cardoso, J. P.; Silva, F. J. G.This chapter presents the necessary requirements for the CE marking of a pressure piping assembled in welded construction. The Quality Management of a welded construction involves well-regulated procedures which, however, are so vast that they acquire great complexity. In fact, there are hundreds of rules to apply to each specific case. In the European Union, the CE marking shows the presumption that the products comply with all the provisions of the applicable directives. This marking is a way to improve the safety of consumers, as well as the guarantee of having a competitive and regulated market, therefore good for the economy itself. Pressure equipment is, as a rule, considered dangerous, and therefore subject to strict and careful regulation. The CE marking is not established as a technical barrier, which prevents countries from exporting their products to the European market. It is just one way of harmonizing and unifying procedures, standards and legislation that has the purpose of completing the European internal market. This paper presents an analysis of how to obtain CE marking of an execution and assembly of steel piping in a formaldehyde plant and which normative ramifications apply.
