  3. 3D printing online learning environements: multiple approaches towards self-learning of engineering design students

    Pikkarainen, Ari; Gaspar, Marcelo
    This paper presents an exploratory study conducted at two Higher Education Engineering Schools, namely in the Lapland University of Applied Sciences (Finland) and in the Polytechnic Institute of Castelo Branco (Portugal), with the aim of constructing digital learning environments that promote increasing learning autonomy to students working with 3D printing technologies in engineering design. Based on pilot blended learning experiences carried-out in both schools, new instructional design solutions are proposed and discussed, aiming at a widespread use of such digital platforms not only for blended and online learning processes in engineering schools, but also as Massive Open Online Courses open to wider communities interested in such technologies.

  5. The co-construction of a bilingual glossary of terms for engineering design technologies as part of learning in engineering trough a collaborative CLIL approach

    Gaspar, Marcelo; Régio, Mónica; Morgado, Margarida
    This case study refers to the collaborative work of pre-engineering and engineering students, supported by their content and English for Specific Purposes (ESP) teachers, on the development of a full semester assignment focusing on the design and construction of a dedicated glossary of terms. Based on a student-centered Content and Language Integrated Learning (CLIL) approach, intermediate tasks were proposed to the students to construct their own personal glossary about the subject. As a result of the combined effort of all actors, a full class bilingual glossary of terms was obtained for engineering design technologies as part of learning in engineering through a collaborative CLIL approach.

  7. Uplink performance evaluation of broadband systems which adopt a massive MU-MIMO approach

    Torres, Paulo; Charrua, Luis; Gusmão, António
    This paper deals with an Orthogonal Frequency Division Multiplexing (OFDM)-based uplink within a Multi User (MU)-Multi-Input Multi-Output (MIMO) system where a ”massive MIMO” approach” is adopted. In this context, either an optimum Minimum Mean-Squared Error (MMSE) linear detection or a reduced-complexity Matched Filter (MF) linear detection are considered. Regarding performance evaluation by simulation, several semi-analytical methods are proposed: one performance evaluation method in the optimum (MMSE) case; two performance evaluation methods in the MF case. This paper includes performance results for uncoded 4-Quadrature Amplitude Modulation (QAM)/OFDM transmission and a MUMIMO channel with uncorrelated Rayleigh fading, under the assumptions of perfect...

  17. Definição de estratégias de intervenção nos edifícios da Santa Casa da Misericórdia de Castelo Branco

    Ramos, A.T.V.F.; Campos, Ana; Silva, J. Mendes
    A Santa Casa da Misericórdia de Castelo Branco possui um conjunto de edifícios contruídos entre 1526 e 2008, sendo atualmente utilizados como creche, asilo de idosos e centro de reabilitação médica. Tanto o ano de construção, como as diversas intervenções realizadas, traduzem-se na diversidade de soluções que se podem encontrar, dentro do mesmo edifício ou entre construções. Este trabalho teve como objetivo identificar a variedade de soluções construtivas existentes e analisar o nível de conforto dos utentes nos edifícios ocupados como lar de idosos. Foram desenhados inquéritos de conforto térmico, aplicados através de entrevista para garantir o seu entendimento pelos...

O projeto do Parque envolve ainda as comunidades locais que vivem próximas ao parque natural. Este trabalho consiste num trabalho efetivo de caracterização das habitações tradicionais locais e dos modos de construir existentes no parque. Importa perceber as soluções utilizadas, compreendendo o seu funcionamento no que respeita à relação com o clima local, assim...
