Using a 3-tier Training Model for Effective Exchange of Good Practices in as ERASMUS+ Project

VISIR+ is an Erasmus+ project that aims to develop educational modules for electric and electronic circuits theory and practice following an enquiry-based teaching and learning methodology. The project has installed five new VISIR remote labs in Higher Education Institutions located in Argentina and Brazil, to allow students doing more experiments and hence acquire better experimental skills, through a combination of traditional (hands-on), remote and virtual laboratories. A key aspect for the success of this project was to motivate and train teachers in the underpinning educational methodology. As such, VISIR+ adopted a 3-tier training process to effectively support the use of VISIR in the Institutions that received it. This process is based on the “train the trainer” approach, which required the participating partner institutions to identify and engage a number of associated partners, interested in using their newly installed remote lab. To measure the quality of the training process, the same satisfaction questionnaire was used in all training actions. This paper presents a detailed description of the training actions along with the analysis of the satisfaction questionnaire results. Major conclusions are that the quality level of the training process remained practically the same across all training actions and that trainees sometimes considered the practical use of the VISIR remote lab as difficult, irrespectively of where and when the training action took place.info:eu-repo/semantics/publishedVersio

Una Federación de Laboratorios Remotos VISIR a través del Proyecto PILAR

Este documento describe cómo un nuevo proyecto Erasmus+, PILAR (Plataform Integration of Laboratories base don the Architecture of visiR), está siendo desarrollado y cómo la puesta en marcha del partenariado y del proyecto está reforzando la red VISIR (Virtual Instrument Systems in Reality) y el Grupo de Interés Especial de VISIR bajo el Consorcio de Laboratorios online (GOLC - Global Online Laboratory Consortium) de la Asociación Internacional de Ingeniería Online (IAOE - International Association of Online Engineering. La Universidad Española para la Educación a Distancia (UNED) coordina este proyecto que tiene como objetivo federar los sistemas existentes (o nuevos) con el fin de utilizar los recursos de manera más efectiva y eficiente, haciendo transparente para el usuario final la elección de los recursos compartidos.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

Using the Fingerprinting Method to Customize RTLS Based on the AoA Ranging Technique

Real-time Locating Systems (RTLSs) have the ability to precisely locate the position of things and people in real time. They are needed for security and emergency applications, but also for healthcare and home care appliances. The research aims for developing an analytical method to customize RTLSs, in order to improve localization performance in terms of precision. The proposed method is based on Angle of Arrival (AoA), a ranging technique and fingerprinting method along with an analytically defined uncertainty of AoA, and a localization uncertainty map. The presented solution includes three main concerns: geometry of indoor space, RTLS arrangement, and a statistical approach to localization precision of a pair of location sensors using an AoA signal. An evaluation of the implementation of the customized RTLS validates the analytical model of the fingerprinting map. The results of simulations and physical experiments verify the proposed method. The research confirms that the analytically established fingerprint map is the valid representation of RTLS’ performance in terms of precision. Furthermore, the research demonstrates an impact of workspace geometry and workspace layout onto the RTLS’ performance. Moreover, the studies show how the size and shape of a workspace and the placement of the calibration point affect the fingerprint map. Withal, the performance investigation defines the most effective arrangement of location sensors and its influence on localization precision

E-Technologies in teaching research methodology for engineers – a case study of the course for international postgraduate students

The Research Methodology course for postgraduate students is challenging, even for an experienced academic teacher. The primary objective of this course is to prepare participants to conduct scientific research and publish the results. This case study presents an original teaching method applied to Research Methodology with Emphasis on Engineering Science, for international engineering students at Blekinge Institute of Technology in Karlskrona, Sweden. The demanding requirements of the course, a varying number of enrolled students, and a large number of assignments which need to be tracked and guided by the teacher are all conditions that need a custom approach and modern tools. The opportunities offered by e-technologies help to fulfil these course requirements. This article shows how e-tools such Itslearning, Doodle, Zotero or scientific database search engines, can be implemented to support the teaching objectives. Using these tools, a single academic teacher can accomplish the eight-week course of Research Methodology, for up to 180 students working in 60 project groups without compromising teaching quality and students’ satisfaction. The course also has been appreciated by colleagues and mentioned in the Master program evaluation of the Swedish Higher Education Authority

Customization of UWB 3D-RTLS Based on the New Uncertainty Model of the AoA Ranging Technique

The increased potential and effectiveness of Real-time Locating Systems (RTLSs) substantially influence their application spectrum. They are widely used, inter alia, in the industrial sector, healthcare, home care, and in logistic and security applications. The research aims to develop an analytical method to customize UWB-based RTLS, in order to improve their localization performance in terms of accuracy and precision. The analytical uncertainty model of Angle of Arrival (AoA) localization in a 3D indoor space, which is the foundation of the customization concept, is established in a working environment. Additionally, a suitable angular-based 3D localization algorithm is introduced. The paper investigates the following issues: the influence of the proposed correction vector on the localization accuracy; the impact of the system’s configuration and LS’s relative deployment on the localization precision distribution map. The advantages of the method are verified by comparing them with a reference commercial RTLS localization engine. The results of simulations and physical experiments prove the value of the proposed customization method. The research confirms that the analytical uncertainty model is the valid representation of RTLS’ localization uncertainty in terms of accuracy and precision and can be useful for its performance improvement. The research shows, that the Angle of Arrival localization in a 3D indoor space applying the simple angular-based localization algorithm and correction vector improves of localization accuracy and precision in a way that the system challenges the reference hardware advanced localization engine. Moreover, the research guides the deployment of location sensors to enhance the localization precision
