- 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.
- TRAILER project overview: tagging, recognition and acknowledgment of informal learning experiencesPublication . García-Peñalvo, Francisco J.; Zangrando, Valentina; Holgado, M. A. C.; Seoane-Pardo, António-M.; Griffiths, David; Forment, M. A.; Mykowska, Aleksandra; Janssen, José; Alves, Gustavo R.; Minović, MiroslavThe evolution of new technology and its increasing use, have for some years been making the existence of informal learning more and more transparent, especially among young and older adults in both Higher Education and workplace contexts. However, the nature of formal and non-formal, course-based, approaches to learning has made it hard to accommodate these informal processes satisfactorily, and although technology bring us near to the solution, it has not yet achieved. TRAILER project aims to address this problem by developing a tool for the management of competences and skills acquired through informal learning experiences, both from the perspective of the user and the institution or company. This paper describes the research and development main lines of this project.
- Uso compartido de módulos educativos para circuitos eléctricos y electrónicos del laboratorio remoto VISIRPublication . Marchisio, Susana Teresa; Concari, Sonia Beatriz; Lerro, Federico; Arregui, Gastón Saez de; Plano, Miguel; Merendino, Claudio; Alves, Gustavo R.VISIR (Virtual Instruments Systems in Reality) is a remote laboratory that has been development in the Blekinge Institute of Technology of Sweden, widely spread at a global Level. The objective of this work is to share in the field of RUEDA community, motivations, basis, progress and projection, with special implications in Argentina, of an Erasmus+ Project: "Educational Modules for Electric and Electronic Circuits Theory and Practice following an Enquiry-based Teaching and Learning Methodology supported by VISIR". This project is funded by the Commission of the European Union at the 2015 call, with the coordination of the Polytechnic Institute of Porto. The project is being developed and it is carried out by a consortium of European and Latin higher education institutions, with the possibility of incorporating adherents. The emphasis is on the strategic and innovation objectives of both technological and educational issues. These objectives are achievable through collaboration, to generate methodological changes in teaching in engineering careers and for enlargement of remote experimentation sharing resources.
- How Remote Labs Impact on Course Outcomes: Various Practices Using VISIRPublication . Marques, Maria A.; Viegas, Maria Clara; Costa-Lobo, Maria Cristina; Fidalgo, André Vaz; Alves, Gustavo R.; Rocha, Joao S.; Gustavsson, IngvarAs technology is increasingly being seen as a fa- cilitator to learning, open remote laboratories are increasingly available and in widespread use around the world. They provide some advantages over traditional hands-on labs or simulations. This paper presents the results of integrating the open remote laboratory VISIR into several courses, in various contexts and using various methodologies. These integrations, all related to higher education engineering, were designed by teachers with different perspectives to achieve a range of learning outcomes. The degree to which these VISIR-related outcomes were accomplished is discussed. The results reect the levels of student engagement and learning and of teacher involvement. From the analysis, a connection between these two aspects was traced, although only related to the user proles. VISIR is shown to be always of benet for more motivated students, but this benet can be maximized under particular conditions and characteristics.

- OCD-FI, On-Chip Debugging and Fault Injection for validating microprocessor based dependable systemsPublication . Fidalgo, André Vaz; Alves, Gustavo R.; Ferreira, José M.This paper proposes a set of modifications to the on-chip debugging infrastructures present in many actual microprocessor cores, with the objective of supporting the validation and verification steps of fault-tolerant mechanisms through fault injection campaigns. A synthesisable microprocessor core for programmable components was used as a target system an. a debugging infrastructure compliant with the NEXUS 5001 proposed standard for on- chip debugging was implemented on this target. To improve the process of real-time memory fault injection, an upgraded infrastructure designated as On-Chip Debugging and Fault Injection (OCD-FI) was developed. The complete system was analysed in terms of area overhead and fault injection capabilities and performance. All elements were designed as synthesizable VHDL modules and evaluated in simulation.

- TRAILER Project (Tagging, Recognition, Acknowledgment of Informal Learning Experiences) a methodology to make learners' informal learning activities visible to the institutionsPublication . García-Peñalvo, Francisco J.; Conde-González, Miguel Ángel; Zangrando, Valentina; García-Holgado, Alicia; Seoane-Pardo, António-M.; Alier, Marc; Galanis, Nikolas; Brouns, Francis; Vogten, Hubert; Griffiths, David; Mykowska, Aleksandra; Alves, Gustavo R.; Minović, MiroslavThe application of information technologies (specially the Internet, Web 2.0 and social tools) make informal learning more visible. This kind of learning is not linked to an institution or a period of time, but it is important enough to be taken into account. On the one hand, learners should be able to communicate to the institutions they are related to, what skills they possess, whether they were achieved in a formal or informal way. On the other hand the companies and educational institutions need to have a deeper knowledge about the competencies of their staff. The TRAILER project provides a methodology supported by a technological framework to facilitate communication about informal learning between businesses, employees and learners. The paper presents the project and some of the work carried out, an exploratory analysis about how informal learning is considered and the technological framework proposed. Whilst challenges remain in terms of establishing the meaningfulness of technological engagement for employees and businesses, the continuing transformation of the social, technological and educational environment is likely to lead to greater emphasis for the effective exploitation of informal learning.
- Run-time defragmentation for dynamically reconfigurable hardwarePublication . Gericota, Manuel G.; Alves, Gustavo R.; Silva, Miguel L.; Ferreira, José M.Reconfigurable computing experienced a considerable expansion in the last few years, due in part to the fast run-time partial reconfiguration features offered by recent SRAM-based Field Programmable Gate Arrays (FPGAs), which allowed the implementation in real-time of dynamic resource allocation strategies, with multiple independent functions from different applications sharing the same logic resources in the space and temporal domains. However, when the sequence of reconfigurations to be performed is not predictable, the efficient management of the logic space available becomes the greatest challenge posed to these systems. Resource allocation decisions have to be made concurrently with system operation, taking into account function priorities and optimizing the space currently available. As a consequence of the unpredictability of this allocation procedure, the logic space becomes fragmented, with many small areas of free resources failing to satisfy most requests and so remaining unused. A rearrangement of the currently running functions is therefore necessary, so as to obtain enough contiguous space to implement incoming functions, avoiding the spreading of their components and the resulting degradation of system performance. A novel active relocation procedure for Configurable Logic Blocks (CLBs) is herein presented, able to carry out online rearrangements, defragmenting the available FPGA resources without disturbing functions currently running.
- Students' perception about using VISIRPublication . Lima, Natércia; Viegas, Clara; Alves, Gustavo R.; Marques, Maria Arcelina; Fidalgo, AndréRemote Labs allows students a complementary way to learn. While working upon their experimental skills, they can practice their autonomy. VISIR is one of the remote labs more used in the field of Electricity and Electronics. This study was conducted in three countries and 14 educational institutions and gathered 952 students' opinions while using VISIR along with other experimental resources. Its goal was to perceive students' opinion about VISIR. Several advantages and disadvantages were identified, regardless the focus of the course or students' level of usage. Positively: “the potential of the equipment”, “access from anywhere/anytime” and “better/more complete understanding”; Negatively: “operating issues”, “problems in understanding” and “poor interface/old fashionable/too simple”.
