Peers' evaluation of a reconfigurable IEEE1451.0-compliant and FPGA-based weblab
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, Mário; Zutin, D. G.; Zackrisson, J.; Rochadel, Willian; Henandez-Jayo, UnaiIt is already more than 10 years that weblabs are seen as important resources to provide the experimental work required in engineering education. Several weblabs have been applied in engineering courses, but there are still unsolved problems related to the development of their infrastructures. For solving some of those problems, it was implemented a weblab with a reconfigurable infrastructure compliant with the...
Reconfigurable IEEE1451-FPGA based weblab infrastructure
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, MárioWeblabs are spreading their influence in Science and Engineering (S&E) courses providing a way to remotely conduct real experiments. Typically, they are implemented by different architectures and infrastructures supported by Instruments and Modules (I&Ms) able to be remotely controlled and observed. Besides the inexistence of a standard solution for implementing weblabs, their reconfiguration is limited to a se...
Embedding instruments & modules into an IEEE1451-FPGA-Based Weblab infrastructure
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, MárioAdopting standard-based weblab infrastructures can be an added value for spreading their influence and acceptance in education. This paper suggests a solution based on the IEEE1451.0 Std. and FPGA technology for creating reconfigurable weblab infrastructures using Instruments and Modules (I&Ms) described through standard Hardware Description Language (HDL) files. It describes a methodology for creating and bind...
Automatização dum carrinho de compras
Costa, Ricardo J.Olhando para a necessidade de auxiliar o movimento dos carrinhos de compras nas grandes superfícies, surgiu a ideia de desenvolver um sistema de accionamento flexível, que pudesse ser adaptado a diferentes tipos de carrinhos. O sistema deveria ser também de baixo custo e ter potencial de industrialização. Como em qualquer sistema de accionamento eléctrico foi necessário dimensionar e seleccionar um controlador ...
Reconfigurable weblabs based on the IEEE1451 Std
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, MárioTechnology plays a double role in Education: it can act as a facilitator in the teaching/learning process and it can be the very subject of that process in Science & Engineering courses. This is especially true when students perform laboratory activities where they interact with equipment and objects under experimentation. In this context, technology can also play a facilitator role if it allows students to per...
FPGA-based weblab infrastructures guidelines and a prototype implementation exa...
Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, Mário; Poley, R.; Wishart, C.Recent trends show an increasing number of weblabs, implemented at universities and schools, supporting practical training in technical courses and providing the ability to remotely conduct experiments. However, their implementation is typically based on individual architectures, unable of being reconfigured with different instruments/modules usually required by every experiment. In this paper, we discuss pract...
A smart layer for remote laboratories
Costa, Ricardo J.; Alves, Gustavo R.; Santos, DomingosCommonly, when a weblab is developed to support remote experiments in sciences and engineering courses, a particular hardware/software architecture is implemented. However, the existence of several technological solutions to implement those architectures difficults the emergence of a standard, both at hardware and software levels. While particular solutions are adopted assuming that only qualified people may im...
Experimenting through the web a linear variable differential transformer
Costa, Ricardo J.; Alves, Gustavo R.Aiming for teaching/learning support in sciences and engineering areas, the Remote Experimentation concept (an E-learning subset) has grown in last years with the development of several infrastructures that enable doing practical experiments from anywhere and anytime, using a simple PC connected to the Internet. Nevertheless, given its valuable contribution to the teaching/learning process, the development of m...
Remote and mobile experimentation: pushing the boundaries of an ubiquitous lear...
Costa, Ricardo J.; Alves, Gustavo R.Concepts like E-learning and M-learning are changing the traditional learning place. No longer restricted to well-defined physical places, education on Automation and other Engineering areas is entering the so-called ubiquitous learning place, where even the more practical knowledge (acquired at lab classes) is now moving into, due to emergent concepts such as Remote Experimentation or Mobile Experimentation. W...
Aneurisma de hiperfluxo próprio da artéria comunicante posterior decorrente de ...
Freitas,José Maria Modenesi; Pieruccetti,Marcos Antônio; Andrade,Guilherme Cabral de; Listik,Ségio; Costa,Ricardo J.; Rodrigues Jr,José CarlosAneurismas próprios da artéria comunicante posterior são extremamente raros possuindo uma incidência que varia de 0,1 a 2,8% de todos os aneurismas. O surgimento de aneurisma intracraniano em virtude de alterações de fluxo por oclusão arterial é descrito na literatura. Apresentamos o caso de homem de 69 anos, vítima de hemorragia subaracnóidea, com diagnóstico de aneurisma próprio da artéria comunicante posteri...
