Resumo: This thesis investigates the impact of bottleneck profiles on cork stopper behavior and performance using non-destructive techniques. Two novel thermal camera-based approaches were developed to assess the diameter recovery rate after extraction and measure absorption along the cork profile. The experimental findings demonstrate that the diameter recovery rate is influenced by the type of bottleneck profile, while the type of cork has a lesser impact. Furthermore, it is observed that the lower half of the cork exhibits a higher diameter recovery rate. Regarding absorption, the results indicate that it is primarily influenced by the type of cork stopper rather than the chosen bottleneck shape, with natural corks displaying significantly higher absorption values. The analysis and acquisition involved the utilization of computer vision and programing software.

Duas novas ferramentas baseadas em câmaras térmicas foram desenvolvidas para avaliar a taxa de recuperação dimensional após a extração e medição da absorção ao longo do perfil da rolha de cortiça. Os resultados experimentais demonstram que a taxa de recuperação dimensional é influenciada pelo tipo de perfil do gargalo, enquanto o tipo de rolha tem um menor impacto. Além disso, observa-se que a metade inferior da rolha apresenta uma maior taxa de recuperação do diâmetro. No que diz respeito à absorção, os resultados indicam que esta é influenciada principalmente pelo tipo de rolha de cortiça e não pela forma de gargalo escolhida, apresentando as rolhas naturais valores de absorção significativamente superiores. A análise e aquisição dos dados envolveu a utilização de software de visão computacional e ferramentas de programação.2025-07-21T00:00:00Z2023-07-19T00:00:00Z2023-07-19info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/39590engPereira, André Rosa Henriquesinfo:eu-repo/semantics/embargoedAccessreponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAP2024-05-06T04:50:00Zoai:ria.ua.pt:10773/39590Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T14:21:44.035102Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse
