Com este estudo pretendeu-se por um lado, verificar o cenário dos estudos que analisaram as práticas educativas com o uso das tecnologias no ensino básico e por outro propor novas perspetivas/propostas de investigação na área das tecnologias no ensino básico. As dimensões do estudo para a clarificação do cenário foram o número de estudos, a área, os tipos de estudos, os tipos de tecnologias e as estratégias imp...
By identifying energy waste streams in vehicles fuel consumption and introducing the concept of lean driving systems, a technological gap for reducing fuel consumption was identified. This paper proposes a solution to overcome this gap, through a modular vehicle architecture aligned with driving patterns. It does not address detailed technological solutions; instead it models the potential effects in fuel consu...
Based on a previously developed mathematical model for fuel consumption of a modular car, here we discuss the cross impacts of engineering scenarios vs. flexibility in use for modular vehicle architectures to achieve the reduction of CO2 emissions targeted by the European Union, in 2009. A systems perspective is adopted in conceptualizing a modular architecture of vehicles. From a theoretical viewpoint, we foun...
Dissertação apresentada para obtenção do grau de Mestre em Redes e Serviços de Comunicação, na Faculdade de Engenharia da Universidade do Porto, sob a orientação do Professor Doutor Raúl Filipe Teixeira Oliveira
The experiments carried out in this investigation were oriented in order to optimize the properties of cork-based agglomerates as an ideal core material for sandwich components of lightweight structures, such as those used in aerospace applications. Static bending tests were performed in order to characterize the mechanical strength of different types of cork agglomerates which were obtained considering distinc...
Este artigo propõe-se a estabelecer correlações entre modelos direcionados à gestão de pessoas nas organizações pós-modernas, através da descrição e da identificação de modelos encontrados na literatura, como também oferecer elementos para a reflexão sobre os conceitos advindos desses arquétipos. O ensaio se enquadra como estudo de natureza descritiva, cujas potencialidades relacionadas ao uso da abordagem holí...
Particle Swarm Optimisers are inherently distributed algorithms where the solution for a problem emerges from the interactions between many simple individual agents called particles. This article proposes the use of the Particle Swarm Optimiser as a new tool for Data Mining. In the first phase of our research, three different Particle Swarm Data Mining Algorithms were implemented and tested against a Genetic Al...
