Abstract [en]

Social demands have promoted an educational approach based on an 'anywhere and anytime' premise. Remote laboratories have emerged as the answer to the demands of technical educational areas for adapting themselves to this scenario. The result has not only benefit distance learning students but has provided new learning scenarios both for teachers and students as well as allowing a flexible approach to experimental topics. However, as any other solution for providing practical scenarios (hands-on labs, virtual labs or simulators), remote labs face several constraints inherited from the subsystems of its deployment - hardware (real instruments, equipment and scenario) and software (analog/digital conversions, communications, workbenches, etc.}. This paper describes the Erasmus+ project Platform Integration of Laboratories based on the Architecture of visiR (PILAR) which deals with several units of the federation installed in different educational institutions and devoted to analog electronics and electrical circuits. Based on the limitations of remote labs, the need for the federation will be justified and its benefits will be described by taking advantage of its strengths. The challenges that have come up during the different stages and the different approaches to design are also going to be described and analyzed. © 2018 IEEE.

Abstract [en]

Remote laboratories are the result of a social movement which promotes accessible educational resources anywhere and anytime through the Internet in order to foster lifelong learning and support online/distance education. A remote laboratory is a real laboratory using real equipment, on which measurements are made through real instruments and which is controllable remotely. The VISIR (Virtual Instrument Systems In Reality) remote laboratory is a system on top of the state-of-The-Art for online wiring and measuring electronic circuits. The PILAR (Platform Integration of Laboratories based on the Architecture of visiR) Erasmus Plus project aims for the federation of five of the existing VISIR nodes, for sharing analog electronics experiments and empowering capacity and resources of each partner, as well as providing access to other educational institutions to a VISIR remote lab through the PILAR consortium. This workshop will allow the attendees to interact with VISIR remote lab, and to be introduced in PILAR framework and joining policies as well as remote lab federation benefits both for VISIR system owners and consumers. © 2019 IEEE.

Abstract [en]

The VISIR+ Project was launched in 2015 with the objective of spreading the use of the VISIR remote laboratory in Latin America, promoting an enquiry-based approach to teaching and learning on electric and electronic circuits. Within the scope of this project, several didactical implementations were achieved both in Argentina and in Brazil. This article describes the latest implementation of VISIR in a pre-university technical school in Argentina (associated partner of the VISIR+ team) in three Physics courses with students having different background knowledge and interests. A set of activities comprising simulations, remote and hands-on experiments were designed in order to engage students in the learning process. The implementation was assessed in terms of the learning objectives and outcomes. Results showed that VISIR is an effective tool to promote active learning. Moreover, this experience seems highly valuable to encourage the dissemination of VISIR in Argentina. © 2018 IEEE.

Abstract [en]

Laboratory experiments play a crucial role in engineering education as they strongly contribute to the development of important skills for the professional practice. This paper addresses a students' understanding gap between simulations and remote labs. These two resources (and namely the remote laboratory VISIR - Virtual Instrument Systems in Reality) have been commonly used on several didactical implementations, along with other didactical resources in different Engineering degrees at the Federal University of Santa Catarina and Polytechnic of Porto School of Engineering. This work, developed in the scope of the VISIR+ Project, intends to evaluate students' perceptions considering simulation and remote lab results. Quantitative and qualitative data were analyzed to better understand how deeply students realize the differences between these resources and their type of data. Preliminary results indicate that a considerable number of student's don't have a clear idea of these differences, even though sometimes they know their definition. Furthermore, this gap does not seem to differ much with the context (country, course, academic year, course content), students' final grades, teacher approach or implemented tasks. © 2017 Association for Computing Machinery.

Abstract [en]

Experimental activities with real components are an essential part of all courses including or devoted to electrical and electronic circuits theory and practice. The knowledge triangle composed of hand-written exercises, simulations and traditional lab experiments has been enriched with the possibility for students to conduct real experiments over the Internet, using remote labs. This tutorial is devoted to one such remote lab named Virtual Instrument Systems in Reality (VISIR). The Global Online Laboratory Consortium (GOLC) elected VISIR as the best remote controlled laboratory in the world, at the first time this distinction was awarded. At the end of this tutorial, attendees are expected to know what is VISIR, what can (not) be done with it, who is currently using it, and how can one integrate it in a given course curriculum.

Abstract [en]

Part I and II of this thesis constitute a theoretical and practical approach on how to open up a laboratory for remote access and enabling students to have access to the equipment 24/7. Part I covers a more general solution for enabling remote access to equipment; the suggested solution can be applied to all types of instruments that can be controlled from a PC based system. Part III and IV of this thesis present an encouragement to collaborate within in the field of remote engineering to utilize the recourses more efficiently. The idea is that universities around the world can share their experiments in a grid laboratory; every university contributes with a small part, but gets access to a wide range of experiments in this grid. Part V of this thesis concerns the modelling and simulation of the remote electronics laboratory with the purpose of estimating the maximum number of simultaneous users without losing the experience of working with a real instrument. The results indicate that one single remote electronics laboratory can handle up to 120 users simultaneously and with 120 users the delay for each user is approximately 2 seconds.

Abstract [en]

This paper reports on a state-of-the-art remote laboratory project called Virtual Instrument Systems in Reality (VISIR). VISIR allows wiring and measuring of electronic circuits remotely on a virtual workbench that replicates physical circuit breadboards. The wiring mechanism is developed by means of a relay switching matrix connected to a PCI eXtensions for Instrumentation (PXI) instrumentation platform. The entire equipment is controlled by LabVIEW server software, in addition to a measurement server software that protects the equipment from hazard connections by verifying input circuit designs, sent by students, before being executed. This paper addresses other approaches such as remote labs based on Data Acquisition Cards (DAQs), NetLab, and RemotElectLab, comparing them with VISIR in order to emphasize its singularity. Topics discussed are as follows: the technical description, software, operation cycle, features, and provided services. In addition, the feedback received by students at several universities and the encountered drawbacks along with the proposed solutions are highlighted. The paper finally addresses the ongoing and future challenges within the VISIR community including its integration with Learning Management Systems (LMSs) and iLab Shared Architecture (ISA), its new hardware version release that is based on LAN eXtensions for Instrumentation (LXI), and its new open platform version that supports federated access.

Abstract [en]

The purpose of this study was to investigate the noise properties and levels of common noise sources in a neonatal intensive care unit (NICU) and in particular inside and around an incubator. Many previous studies have been made on noise levels in NICU, frequently focusing on A-weighted sound levels. In this study it was not assumed that infant's hearing follows the same equal loudness curve as adults and hence instead of A-weighting, short time averaged sound spectra in the frequency range 20 Hz to 20 kHz was logged to identify the frequency distribution of specific noise generating events. It was seen that alarms and CPAP air-flow increased the noise level by up to 8 dB outside but was barely noticed inside when considering the un-weighted noise level. However, by analyzing individual frequencies, most events were noticeable inside the incubator. For instance, frequencies above 1 kHz were increased by 10 dB inside and 11 dB outside the incubator when CPAP was turned on. Opening and closing the incubator increased the un-weighted noise level by 8 dB inside and 7 dB outside.

Abstract [en]

This paper presents a novel and advanced remotely controlled laboratory for conducting Active Noise Control (ANC), acoustic and Digital Signal Processing (DSP) experiments. The laboratory facility, recently developed by Blekinge Institute of Technology (BTH) Sweden, supports remote learning through internet covering beginners level such as simple experimental measurements to advanced users and even researchers such as algorithm development and their performance evaluation on DSP. The required software development for ANC algorithms and equipment control are carried out anywhere in the world remotely from an internet-connected client PC using a standard web browser. The paper describes in detail how ANC, acoustic and DSP experiments can be performed remotely The necessary steps involved in an ANC experiment such as validity of ANC, forward path estimation and active control applied to a broad band random noise [0-200Hz] in a ventilation duct will be described in detail. The limitations and challenges such as the forward path and nonlinearities pertinent to the remote laboratory setup will be described for the guidance of the user. Based on the acoustic properties of the ventilation duct some of the possible acoustic experiments such as mode shapes analysis and standing waves analysis etc. will also be discussed in the paper.
