The VISIR Implementation Process at IFSC - problems, obstacles and solutions

In recent year, the use of remote laboratories applied to teaching has been more frequent in several educational institutions around the world. The benefits on the learning process are easy to verify. In addition, remote laboratories bring in their application, operational advantages associated to component inventory, equipment maintenance, security, and others practical issues. Considering this, it is intuitive that the implantation of a remote laboratory and its use is easily recognized and accepted by the users, namely, students and teachers. This paper aims to present the obstacles and advantages observed in the implantation of the virtual laboratory VISIR (Virtual Instruments Systems in Reality) at Federal Institute of Santa Catarina - IFSC, as well as the obtained results.info:eu-repo/semantics/publishedVersio

A remote lab to support e-learning on FPAA

Teaching analog and digital electronic subjects is not a trivial task because is necessary to use opposite methodologies. The electronic design in the digital field is centered in the use of microprocessor and FPGA based circuits using high level programing/configuring languages. The counterpart analog design is traditionally based in the use of elementary components associated with macroblocks such operational amplifiers in order to built-up the wanted mission circuit. Some few components, as the FPAA, are analogically configurable in a similar manner already used with the FPGA. However the use of this kind of components is not straightforward once is necessary to acquire some concepts not taught in the traditionally analog electronic classes.N/

A remote lab to support e-leaning on Programmable System-on-Chip (PSoC)

The design flow in analog and digital electronics are quite opposite as result of each area maturation state. So, are also the teaching methodologies, being challenging for both teachers and students. The electronic design in the digital field is centered in the use of microprocessor and FPGA based circuits using high level programing/configuring languages. In a different way, the analog design is traditionally based on the use of elementary components associated with macroblocks, such operational amplifiers in order to built-up the wanted mission circuit. Some analog programmable components, as the PSoC, are analogically configurable in a manner similar to those already used in the digital domain. The use of this type of components is not straightforward, being necessary to get some concepts traditionally not taught in the analog electronic classes. The training using PSoC is then indispensable to verify if the programmed circuit corresponds to the intended one.N/

Advances in smart grids - benefits on sharing background experiences from Portugal, Central Europe and Brazil

This paper presents ELECON - Electricity Consumption Analysis to Promote Energy Efficiency Considering Demand Response and Non-technical Losses, an international research project that involves European and Brazilian partners. ELECON focuses on energy efficiency increasing through consumer´s active participation which is a key area for Europe and Brazil cooperation. The project aims at significantly contributing towards the successful implementation of smart grids, focussing on the use of new methods that allow the efficient use of distributed energy resources, namely distributed generation, storage and demand response. ELECON puts together researchers from seven European and Brazilian partners, with consolidated research background and evidencing complementary competences. ELECON involves institutions of 3 European countries (Portugal, Germany, and France) and 4 Brazilian institutions. The complementary background and experience of the European and Brazilian partners is of main relevance to ensure the capacities required to achieve the proposed goals. In fact, the European Union (EU) and Brazil have very different resources and approaches in what concerns this area. Having huge hydro and fossil resources, Brazil has not been putting emphasis on distributed renewable based electricity generation. On the contrary, EU has been doing huge investments in this area, taking into account environmental concerns and also the economic EU external dependence dictated by huge requirements of energy related products imports. Sharing these different backgrounds allows the project team to propose new methodologies able to efficiently address the new challenges of smart grids

Remote laboratory: Application and usability

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.info:eu-repo/semantics/acceptedVersio

Spreading remote lab usage: A system — A community — A Federation

Experiments have been at the heart of scientific development and education for centuries. From the outburst of Information and Communication Technologies, virtual and remote labs have added to hands-on labs a new conception of practical experience, especially in Science, Technology, Engineering and Mathematics education. This paper aims at describing the features of a remote lab named Virtual Instruments System in Reality, embedded in a community of practice and forming the spearhead of a federation of remote labs. More particularly, it discusses the advantages and disadvantages of remote labs over virtual labs as regards to scalability constraints and development and maintenance costs. Finally, it describes an actual implementation in an international community of practice of engineering schools forming the embryo of a first world wide federation of Virtual Instruments System in Reality nodes, under the framework of a project funded by the Erasmus+ Program.info:eu-repo/semantics/publishedVersio

Chapter 1

Experimenting is fundamental to the training process of all scientists and engineers. While experiments have been traditionally done inside laboratories, the emergence of Information and Communication Technologies added two alter-natives accessible anytime, anywhere. These two alternatives are known as virtual and remote labs, and are sometimes indistinguishably referred as online labs. Sim-ilarly to other instructional technologies, virtual and remote labs require some ef-fort from teachers in integrating them into curricula, taking into consideration sev-eral factors that affect their adoption (i.e. cost) and their educational effectiveness (i.e. benefit). This chapter analyses these two dimensions and sustains the case where only through international cooperation it is possible to serve the large num-ber of teachers and students involved in engineering education. It presents an ex-ample in the area of Electrical and Electronics Engineering, based on a remote lab named Virtual Instruments System in Reality, and it then describes how a number of European and Latin-American institutions have been cooperating under the scope of an Erasmus+ project2, for spreading its use in Brazil and Argentina.info:eu-repo/semantics/publishedVersio
