Digital vaulted territories
Batista Pacheco, Mafalda; Falcão, Ana Paula; Gomes, Maria da Gloria; Volzone, Rolando; Folgado, Mariana Parreira; Costa, SérgioWithin the scope of the Vaulted South Project, an open-source platform was implemented using Omeka-S software to store and interconnect digital data and enable research and dissemination – based on the FAIR principles (Findable, Accessible, Interoperable and Reusable) – of knowledge of vernacular vaulted buildings in Southern Portugal. The corpus was generated by crossing several methodologies and interrelated ...
Types of vaults in southern Portuguese architecture
Costa, Sérgio; Vieira Caldas, João; Batista Pacheco, MafaldaMuch of the literature on Portuguese vernacular architecture has conveyed the notion of a ‘vaulted south’, understood as the territory where a certain roof-building technique is preferentially used across all building typologies. In Portugal, the massive presence of vaulted houses in the Alentejo and Algarve is practically common knowledge, but scientific research on this topic is only slowly expanding. Other t...
Composite SVR based modellingof an Industrial Furnace
Santos, Daniel; Rato, Luís; Gonçalves, Teresa; Barão, Miguel; Costa, Sérgio; Malico, Isabel; Canhoto, PauloIndustrial furnaces consume a large amount of energy and their operating points have a major influence on the quality of the final product. Designing a tool that analyzes the combustion process, fluid mechanics and heat transfer and assists the work done during energy audits is then of the most importance. This work proposes a hybrid model for such a tool, having as it base two white-box models, namely a detail...
Development of a reduced-order model of an industrial billet heating furnace
Alvarez, Frederico; Costa, Sérgio; Santos, Daniel; Canhoto, Paulo; Malico, Isabel; Rato, Luís; Gonçalves, Teresa; Barão, Miguel; Lima, Rui PedroThis work is part of the ongoing efforts under the Audit Furnace project to develop a reduced-order model (ROM) that allows for fast analysis of combustion, fluid flow and heat transfer processes that occur inside industrial furnaces. A billet heating furnace is considered here, which uses propane as fuel and processes circa 5000 kg of material per hour with a billet temperature set point at the exit of 745 ºC....
Parametric study of local laser heat treatment technology on multi forming of a...
Pereira, Rui; Peixinho, Nuno; Costa, Sérgio; Blanco, Vitor; Carneiro, VitorThe effectiveness of local laser heat treatment technology to enhance the in situ formability of steels and aluminum alloys has already been widely acknowledged for the one-step forming of components with simple shape geometries. The present study demonstrates that this technology is also able to significantly improve the formability of a complex shaped multi-forming industrial part. An industrial grade advance...
Experimental and numerical assessment of the impact test performance between tw...
Peixinho, Nuno; Costa, Sérgio; Mendonça, João PedroThis paper presents an integrated approach for an ultimate high-performance safety toe cap with significant milestones in slim design and weight saving. The study of crashworthiness properties was performed through impact-crash test conditions exploring the potential of applicant solutions by the combination of an advanced high-strength steel and enhanced geometric stiffening models. The structural response for...
Colorectal Screening Program in Northern Portugal: First Findings
Monteiro, Hugo; Tavares, Fernando; Reis, João; Ferreira, Gustavo; Campos, M. José; Costa, Sérgio; Carvalho, Laura; Carvalho, João; Pedroto, IsabelIntroduction: In Portugal, a colorectal cancer screening program based on faecal immunochemical test followed by colonoscopy was shown to be cost-effective for individuals between 50 and 74 years old. We report the first findings of the implementation of a population-based program In Northern Portugal.Material and Methods: In the pilot phase, eligible subjects were allocated either to a direct mailing invitatio...

Fluorescent bis-calix[4]arene-carbazole conjugates: synthesis and inclusion com...
Barata, Patrícia; Costa, Alexandra I.; Costa, Sérgio; Prata, José V.Supramolecular chemistry has become a central theme in chemical and biological sciences over the last decades. Supramolecular structures are being increasingly used in biomedical applications, particularly in devices requiring specific stimuli-responsiveness. Fullerenes, and supramolecular assemblies thereof, have gained great visibility in biomedical sciences and engineering. Sensitive and selective methods ar...
