- A practical approach to teaching the propagation of electromagnetic interference in printed circuit boardsPublication . Schlichting, Luis C. M.; Liz, Muriel B. de; Ferreira, Golberi de S.; Alves, Gustavo R.; Felgueiras, CarlosThe study of Electromagnetic Compatibility (EMC) has, since 1990 [1] [2] presented greater evolution. However, due to costs of measuring equipment for measuring the Electromagnetic Interference (EMI) generated and propagated from equipment under test (EUT), a number of educational institutions cannot ou have difficult in teaching the phenomena associated to EMI generation, propagation and mitigation. Therefore, in last years, teachers of the EMC subject in Electronic Engineering and Technology in Electronic Systems courses of the Department of Electronics of the Federal Institute of Santa Catarina have developed experiments that allow the study of EMC/EMI using simulator software packages and usual bench equipment as oscilloscopes and signal generators. This work intend to present practical experiments that enable to the undergraduate students the observation of concepts and techniques associated to EMC and EMI, without concerns with a controlled environment, neither with the precision at the measuring of the induced voltage levels. The aim is to present the qualitative aspect and compare the results for certain situations.
- Remote laboratory: Application and usabilityPublication . Schlichting, Luis C. M.; Ferreira, Golberi de S.; Bona, Daniel Dezan de; Faveri, Flávio de; Anderson, José A.; Alves, Gustavo R.The practice and the hands-on are essential for technical and professionals skills, even in controlled situations. Due to that, the use of laboratories during the learning process is fundamental, although it has been more difficult to support such kind of infrastructure locally, which brings the challenge to find alternatives. On the other hand, the Brazilian law establishes that higher education institutions can offer a complete curricula or a part of the curricula by using E-learning, what builds a scenario to use remote laboratories. This work presents the alternatives for the use of remote laboratories, showing that this idea can be spread and applied in different technical areas allowing students and professors to accomplish experiments in a safe and flexible environment trough the internet in real remote laboratories. This work also shows preliminary discussions of a first experiment with technical high school students using remote laboratories.
- A sustainable approach to let students do more real experiments with electrical and electronic circuitsPublication . Alves, Gustavo R.; Pester, Andreas; Kulesza, Wlodek; Silva, Juarez Bento; Pavani, Ana; Pozzo, María Isabel; Marchisio, Susana; Fernandez, Ruben; Oliveira, Vanderli; Schlichting, Luis C. M.; Felgueiras, Carlos; Viegas, Clara; Fidalgo, André; Marques, Maria Arcelina; Costa, Ricardo; Lima, Natércia; Castro, Manuel; García-Zubía, JavierThe present paper focus on the use of remote laboratories in higher education from a sustainability viewpoint. The particular case of engineering education, and, within it, the more specific subject of experiments with electrical and electronic circuits is presented first, to then discuss the benefits of using remote labs, while considering the three dimensions of sustainable development, i.e.: economic practice, environmental protection, and social integration. The paper debates how remote labs address each dimension.
