Demonstração dos resultados dos projetos ALFA LEAL e RexNet

O presente artigo descreve o âmbito, objetivos, atividades e resultados obtidos nos projetos LEAL e RexNet, fi nanciados pelo programa América Latina – Formação Acadêmica (ALFA), da Comissão Européia (CE). O aspecto mais relevante consistiu na realização de atividades conjuntas que permitiram estabelecer e fortalecer laços de cooperação entre as duas redes, cada uma constituída por mais de dez Instituições de Ensino Superior (IES) da Europa e da América Latina. É de realçar ainda a realização de um workshop conjunto integrado na Conferência Internacional em Aprendizagem Interativa e Combinada Auxiliada por Computador (ICBL’07) que decorreu em Florianópolis, Santa Catarina, Brasil, em Maio de 2007, sob a organização do CEFET/SC

Acquisition of higher-order experimental skills through remote and virtual laboratories

Remote laboratories are physical spaces with real apparatus and real instruments connected to the Internet. They allow both students and teachers to remotely conduct real experiments through a simple web browser.info:eu-repo/semantics/publishedVersio

Remote experimentation: integrating research, education, and industrial application

This paper presents a low-cost scaled model of a silo for drying and airing cereal grains. It allows the control and monitor of several parameters associated to the silo's operation, through a remote accessible infrastructure. The scaled model consists of a 2.50 m wide × 2.10 m long plant with all control and monitor capacities provided by micro-Web servers. An application running on the micro-Web servers enables storing all parameters in a data basis for later analysis. The implemented model aims to support a remote experimentation facility for technological education, research-oriented tutorials, and industrial applications. Given the low-cost requirement, this remote facility can be easily replicated in other institutions to support a network of remote labs, which encompasses the concurrent access of several users (e.g. students)

From cheating to teaching: a path for conversion of illegal gambling machines

Video poker machines, a former symbol of fraud and gambling in Brazil, are now being converted into computer-based educational tools for Brazilian public primary schools and also for governmental and non-governmental institutions dealing with communities of poverty and social exclusion, in an attempt to reduce poverty risks (decrease money spent on gambling) and promote social inclusion (increase access and motivation to education). Thousands of illegal gambling machines are seized by federal authorities, in Brazil, every year, and usually destroyed at the end of the criminal apprehension process. This paper describes a project developed by the University of Southern Santa Catarina, Brazil, responsible for the conversion process of gambling machines, and the social inclusion opportunities derived from it. All project members worked on a volunteer basis, seeking to promote social inclusion of Brazilian young boys and girls, namely through digital inclusion. So far, the project has been able to convert over 200 gambling machines and install them in over 40 public primary schools, thus directly benefiting more than 12,000 schoolchildren. The initial motivation behind this project was technology based, however the different options arising from the conversion process of the gambling machines have also motivated a rather innovative and unique experience in allowing schoolchildren and young people with special (educational) needs to access to computer-based pedagogical applications. The availability of these converted machines also helps to place Information and Communication Technologies (ICT) in the very daily educational environment of these children and youngsters, thus serving social and cultural inclusion aspects, by establishing a dialogue with the community and their technological expectations, and also directly contributing to their digital literacy

Impact of Increasing Electric Vehicles Demand on the Distribution Network: A Power Balance Analysis

The 8th International Conference on Energy and Environment Research ICEER 2021, 13–17 SeptemberIn the coming years, we will witness a change in the current car fleet sales, from traditional fuel engines towards electrical vehicles (EVs), particularly passenger light-duty vehicles. They plug into the grid and store the electricity in rechargeable batteries; therefore, the widespread adoption of EVs will bring many challenges for the distribution network. Forecasting the impact of EVs on distribution networks is a difficult task given the uncertainty on the potential evolution of their sales. This study forecasts the EVs sales growth for the 2020-2030 decade in 3 possible evolution scenarios, carried out for a given Portuguese regional area. The demanded energy for charging the batteries was estimated, considering one long and one short route. The analysis was applied to three EVs models: Nissan Leaf, Tesla Model 3, and Renault Zoe. The impacts on the rated power of the distribution network are calculated for the three scenarios, and the results are presented, standing out the considerable insufficient power at peak hN/

Electric vehicles growth until 2030: Impact on the distribution network power

REXIB: Remote Experiments Interface Builder

Remote Experimentation is an educational resource that allows teachers to strengthen the practical contents of science & engineering courses. However, building up the interfaces to remote experiments is not a trivial task. Although teachers normally master the practical contents addressed by a particular remote experiment they usually lack the programming skills required to quickly build up the corresponding web interface. This paper describes the automatic generation of experiment interfaces through a web-accessible Java application. The application displays a list of existent modules and once the requested modules have been selected, it generates the code that enables the browser to display the experiment interface. The tools main advantage is enabling non-tech teachers to create their own remote experiments

An integrated reusable remote laboratory to complement electronics teaching

The great majority of the courses on science and technology areas where lab work is a fundamental part of the apprenticeship was not until recently available to be taught at distance. This reality is changing with the dissemination of remote laboratories. Supported by resources based on new information and communication technologies, it is now possible to remotely control a wide variety of real laboratories. However, most of them are designed specifically to this purpose, are inflexible and only on its functionality they resemble the real ones. In this paper, an alternative remote lab infrastructure devoted to the study of electronics is presented. Its main characteristics are, from a teacher's perspective, reusability and simplicity of use, and from a students' point of view, an exact replication of the real lab, enabling them to complement or finish at home the work started at class. The remote laboratory is integrated in the Learning Management System in use at the school, and therefore, may be combined with other web experiments and e-learning strategies, while safeguarding security access issues
