Life without mobility is inconceivable. To enable this connectivity, one must find a way to progress towards a more sustainable transportation. In the aviation industry, a comprehensive understanding of greening technologies such as electrification of the propulsion system for commercial aircraft is required. A hybrid-electric propulsion concept applied to a regional aircraft is studied in the context of the FutPrInt50 project. To this end, the hybrid-electric propulsive system components are modeled, validated, and evaluated using computational and experimental data presented in the literature. The components are then assembled to construct the three powertrains for the hybrid-electric propulsion systems (Series, Parallel and Turboelectric) and parametric studies are carried out to study the influence of various battery parameters and hybridization factor. The performance results for a simple mission profile are generated. Together with a thermal management system, multi-objective optimization studies for the different architectures are then performed, with the power hybridization factor as the design variable and minimization of total mass and emissions as objective functions.
O presente estudo incide sobre a investigação sistemática que temos vindo a realizar desde 2019 sobre Marcelo Leitão, penúltimo Procurador-Geral da Vice-Província da China, no âmbito do projecto «Res Sinicae. Base Digital de Fontes Documentais em latim e em português sobre a China (Séculos XVI a XVIII). Levantamento, edição, tradução e estudos».Sobre esse jesuíta, constante no núcleo dos procuradores portugueses, importa referir que foi pontualmente mencionado em elencos de fontes,
O presente texto resulta da análise dos vários relatos referentes à dupla canonização de Luís Gonzaga (1568-1591) e Estanislau Kostka (1550-1568), em 1726, que teve particular eco no contexto nas celebrações da Companhia de Jesus em Portugal. As vertentes dos programas, da arquitetura e da cenografia contribuíram para a metamorfose dos espaços e, uma vez mais, para se afirmar a capacidade que esse instituto religioso teve para organizar celebrações e outros atos performativos, que envolveram a corte e vários segmentos sociais. Considerando os diversos testemunhos que narram estes acontecimentos, procurou-se colocar em diálogo as festas de Braga, Santarém, Lisboa e Évora, interrogando a obra e compreendendo as linhas comuns a todos estes jubileus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
