Small scale hydropower has a considerable untapped potential, able to contribute to the increased energy demand. The integration of these systems into microgrids is an emerging solution for the electrification of remote areas and for self-sustainable power systems. This paper is devoted to the design optimization of grid-connected pico-hydro systems using conventional photovoltaic inverters, providing...
Technology based and hands-on experimental activities in engineering are currently under way in a joint venture involving Portuguese and Brazilian higher education institutions, whose goals include sharing of resources and instructor experiences in using alternative ways of implementing experimental training in engineering, as well as investigating the reaction of students with different cultural...
Pico-hydro power generation has a considerable untapped potential, able to contribute to the increased energy demand whilst ensuring a low environmental impact. The integration of these systems into microgrids is an emerging solution for the electrification of remote regions and also for self-sustainable power systems. The integration of cheap and wide spread technologies to interface small capacity...
Earth retaining walls are common civil engineering structures. What goes on behind them in terms of soil-wall interaction has a sound theoretical framework but its physical significance can be further enhanced in pedagogical terms by recourse to experimental setups and numerical simulations. This paper presents a set of numerical studies designed to raise student awareness of the factors controlling...
This demo presents a set of virtual tools developed as learning aids for soil mechanic students in civil engineering. These tools will be used in the current semester and they are complemented by simple experimental setups aimed at fostering do-it-yourself exploratory activities. All these contents will be demonstrated during the Demo Session and are available at http://onlinelab.fe.up.pt/ on the...
Os schwannomas retroperitoneais são tumores raros, maioritariamente benignos e com origem na bainha dos nervos periféricos. O diagnóstico pré‐operatório correto é frequentemente impossível. São raras as descrições de exérese laparoscópica de schwannomas nesta topografia. Pretendemos apresentar um caso de um schwannoma retroperitoneal tratado por via laparoscópica.Homem de 61 anos, com um achado acidental...
Every civil engineering structure relies on the good performance of its foundation, whose function of safely transmitting load to the ground is carried out away from our eyes. With the purpose of giving visibility to this process this paper describes two IT tools and a small-scale experimental setup that have been developed as learning aids for the study of the behavior and bearing capacity of shallow...
This work reports on a tutorial which complements an online experiment for training purposes in mechanical material properties characterization, bridging the gap between experimental activity and theoretical concepts.
Seepage or groundwater flow is an essential topic in the geotechnical training of civil engineering students. The appropriate understanding and control of seepage phenomena is fundamental for the safe design of water retaining works such as embankment dams. Catastrophic failure of such massive structures, due to internal erosion processes caused by deficient control of seepage, has caused many casualties...
Augmented reality technology can be used in training and learning environments to increase the level of users' immersion. Taking advantage of this technology a tool has been developed for helping students to re-observe experimental results of groundwater flow in small scale models of embankment dams. It is available to be used any time after experimental sessions at students' request and without requiring...
The paper describes the development of an interactive video focusing on groundwater flow phenomena in embankment dams. Using digital video, html and javascript an interactive web application has been developed to provide a learning tool for soil mechanics students. The web application is able to indicate further references through social networks in order to stimulate interest and promote deeper learning...
This paper describes two initiatives for dissemination of science and technology using multimedia tools. One consists in a set of 250 one-minute programs about engineering topics which were broadcast by TV, radio and the multimedia online platform of a daily journal. The other is a collection of videos produced by a research unit in two alternative formats aimed at specialist and general viewers....
Nowadays science communicators have at their disposal a variety of tools to convey information. Video stands out among them as an effective means for disseminating educational content because of its unique features: it is multi-sensory, dynamic and capable of engaging the viewer's attention. The use of video clips in engineering education is illustrated with applications in the area of groundwater...
Constant knowledge advancement and innovation progress is one of the components of the University mission. These enhancements are mainly supported by academics and students. Student involvement in research and development activities at any level, particularly at freshman level while they are still adapting to the higher education learning style, is sometimes considered unsuitable. This perception...
Universidade Júnior provides 11 to 17 years old secondary school pupils with the opportunity to get in touch with university life by offering an action packed variety of learning experiences during 5 weeks in July and September. This very busy and varied offer requires careful preparation which involves mentoring activities that are developed at two levels: between faculty and the junior tutors and...
