This electronic puppet is an assistive educational technology designed especially for non-oralized children. The purpose of this is article is present a project of assistive educational technology named Electronic Puppet. In order to do this, we use the electronic puppet, that fits in the concept of internet of things, connecting himself to the multimedia system with images, sound, animations and...
A future thermonuclear fusion reactor relies on the real-time control of, among others, instabilities and plasma position. At the ISTTOK tokamak, a novel approach of a real-time diagnostic system to control the vertical plasma position (in a 100-$\mu \text{s}$ closed-loop) was implemented by: 1) developing the heavy ion beam diagnostic (HIBD) to perform the position measurement and 2) combining...
The remote laboratories at IST (Instituto Superior Técnico), e-lab, serve as a valuable tool for education and training based on remote control technologies. Due to the high number and increase of remotely operated experiments a generic protocol was developed to perform the communication between the software driver and the respective experimental setup in an easier and more unified way. The training...
In this paper, we propose a new Motion Estimation algorithm based on low discrepancy sequences, essentially quasi-random sequences used as point sampling to compute multivariate integral approximations by methods such as Monte-Carlo. Our evaluation of the proposed method took into consideration PSNR mean values, computational effort and bit-rate. The results support that the proposed algorithm entitled...
This paper presents a proactive maintenance scheme for the prediction of faults in electrical valves. In our case study, these valves are used for controlling the oil flow in a distribution network. A system implements temporal self-organizing maps for the prediction of faults. These faults lead to deviations either on torque, on the valve end position or on opening/closing time. For fault prediction,...
