- A comprehensive VISIR bibliographical referencePublication . Silva, Mariana Miguel; Fidalgo, André; Marques, Maria Arcelina; Alves, Gustavo R.; Salah, Razwan M.; Jacob, Frederico L.VISIR (Virtual Instrument Systems in Reality) is a remote laboratory environment in use in research and academic institutions since 2001. This paper presents a comprehensive VISIR bibliographical reference, including a performance analysis, which reviews the publication data and the citation indexes, and a science mapping, that presents the cognitive structure. The procedure to retrieve, aggregate, process, and analyze data is based on documented sources and is also presented in the article, including some comments on specific issues faced while applying the proposed methodology. The paper characterizes the publication evolution over time, the most prolific authors and their networks, the main research topics, the most frequent sources, and the most cited documents. The available results show a mature and evolving collaborative network and an expansion trend that allows predicting that VISIR is not only the source of many academic and applied research publications, but also a popular and continuously developing remote laboratory and the basis of a very active community.
- Experimenting in PILAR Federation: a Common Path for the FuturePublication . Garcia-Loro, Felix; Macho, Alejandro; San Cristobal, Elio; Diaz, Gabriel; Castro, Manuel; Kulesza, Wlodek; Gustavsson, Ingvar; Nilsson, Kristian; Fidalgo, André; Alves, Gustavo R.; Marques, Maria Arcelina; Hernandez-Jayo, Unai; Garcia-Zubia, Javier; Kreiter, Christian; Oros, Ramona; Pester, Andreas; Garbi-Zutin, Danilo; Auer, Michael; Garcia- Hernandez, Carla; Tavio, Ricardo; Valtonen, Kati; Lehtikangas, ElinaThe PILAR (Platform Integration of Laboratories based on the Architecture of visiR) Erasmus Plus project started in September 2016 and will last three years. The core of the PILAR project is the VISIR remote laboratory —Virtual Instruments System In Reality—. The project aims for a federation of five of the existing VISIR nodes, sharing experiments, capacity and resources among partners, and to provide access to VISIR remote lab, through PILAR consortium, to students from other educational institutions. PILAR will be the framework from which management tasks will be performed and laboratories/experiments will be shared. PILAR will also foster the Special Interest Group of VISIR under the Global Online Laboratory Consortium (GOLC) of the International Association of Online Engineering (IAOE).
- The EOLES project Remote Labs across the MediterraneanPublication . Fidalgo, André Vaz; Gericota, Manuel G.; Barataud, Denis; Andrieu, Guillaume; Craemer, Renaat De; Cristea, Mihai; Benachenhou, Abdelhalim; Ankrim, Mohammed; Bouchlaghem, Karim; Ferreira, PauloThis paper describes the concept, methodology and first steps of an EU supported TEMPUS project EOLES (Electronics and Optics e-Learning for Embedded Systems). Its aim is the creation of a 3rd year Bachelor degree that relies exclusively on e-learning and remote laboratories. The project involves 15 institutions from four European countries and three North African countries. The proposed course will be run from several institutions simultaneously and should be accredited as a formal specialization year in all partner institutions, awarding 60 ECTU (European Transfer Credit Units). The course will integrate a Virtual Learning Environment and a Distributed Laboratory.
- VISIR+ project follow-up after four years: Educational and research impactPublication . Pavani, Ana M.B.; Viegas, Clara; Lima, Natércia; Alves, Gustavo R.; Marques, Arcelina; Fidalgo, André; Jacob, Frederico; Silva, Juarez B.; Marchisio, Susana; Schlichting, Luís; Soria, Fernando; Lerro, Federico; Barbosa, William de S.; Steinbach, Reginaldo; Mafra, PauloThis full paper addresses an innovative practice in the experimental teaching/learning in Engineering courses. Engineering is a practical profession where doing is the key. Experimental work and the immersing in the lab environment (hands-on, simulations, remote labs) helps students to construct and strengthen their knowledge. The VISIR+ Project (ERASMUS+), launched in November 2015 and concluded in Abril 2018, intended to disseminate VISIR – Virtual Instrument Systems in Reality (the most used remote lab in electric and electronics area of expertise) in Latin American countries (Argentina and Brazil) by installing a system in five Higher Educational Institutions. It involved 13 educational institutions, 25 different courses, several of them with successive didactical implementations. It comprised 49 teachers and 1,595 students. During the project about 27 research papers were published disseminating the projects’ results. At the end of the project, the expectations were that the impact could remain in the long-term promoting VISIR remote lab and the dissemination of good practices. The project ended four years ago, and each installed VISIR system continued to promote teaching diversification using different experimental resources (including VISIR) then contributing to student learning. The aim of this work is to understand the impact of these didactical practices while using VISIR in these last years. This study was based on a questionnaire complemented with an interview with each person of contact. The results point to an increase of VISIR’s usage in almost all institutions, particularly during the pandemic period. Overall, the educational impact involved more than 23 different institutions, 45 courses (most of them with several editions), 118 teachers and 4,866 students. The impact in the scientific community implied additional 31 publications with VISIR as its main core. These numbers support the sustainability of the VISIR+ project over the years, positively contributing to a more diversified engineering education of these students and their experimental competences development.
- An educational remote laboratory for controlling a signal conditioning circuit with an LDR sensorPublication . Costa, Ricardo; Bastos, Paulo; Alves, Gustavo R.; Felgueiras, Carlos; Fidalgo, AndréIn the past few years, the technologic evolution of communication and information systems had a major impact in our lives. In education, this evolution broke some geographical barriers, facilitating students’ access to real laboratories using a simple device connected to the Internet, contributing therefore to improve teaching and learning methods. To support this evolution, this paper describes a remote laboratory that provides students’ access to a typical electronic instrumentation system. Through a set of webpages, users can remotely control a light intensity sensed through a Light Dependent Resistor (LDR) sensor connected in an arm of a configurable Wheatstone Bridge (WB), whose output differential voltage are amplified / attenuated by an Instrumentation Amplifier (IA) circuit. Through this laboratory, users are able to control several components of a typical instrumentation system, visualize changes and analyze some measurements, in the same way as they would do in a traditional hands-on laboratory. An overview of the developed remote laboratory and a contextualization within other available solutions are presented in this paper. At the end, some considerations for its adoption in education are described.
- Using VISIR Remote Lab in the Classroom: Case of Study of the University of Deusto 2009-2019Publication . García-Zubía, Javier; Cuadros, Jordi; Hernández-Jayo, Unai; Serrano, Vanessa; Angulo, Ignacio; Alves, Gustavo R.; Fidalgo, AndréDuring the last ten years, the University of Deusto is using VISIR remote lab for analog electronics in the Faculty of Engineering. Present paper shows how we are using the VISIR with students, and its results. It is a catalog of experiments to invite other universities to join the VISIR consortium. Ongoing and future research in VISIR are also presented
