Adaptive Control - SIMULINK Implementation
Tiago Filipe de Pinho Francisco de Oliveira; Alexandre Manuel M. Nunes MotaSIMULINK is a software package that, with the well known MATLAB, executes simulation of sampled and/or continuous systems. This text describes how to adapt SIMULINK to real-time process control execution, in particular, of adaptive controllers.

Effects of Age-Related Cognitive Deficits on EEG Phase Coherence
Ferreira, Daniela S.; Reis, Joana; Portugal, Ana Maria; Pinho, Francisco; Jacinto, Luís; Dias, Nuno S.Body and brain undergo several changes with aging. One of these changes is the loss of neuroplasticity, which leads to the decrease of cognitive abilities. Hence the necessity of stopping or reversing these changes is of utmost importance to contemporary society. In the present work, electroencephalogram (EEG) markers of cognitive decline are sought whilst the subjects perform the Wisconsin Card Sorting Test (W...
A Wireless EEG Acquisition Platform based on Embedded Systems
Pinho, Francisco; Correia, José Higino; Dias, Nuno S.This paper proposes a wireless EEG acquisition platform based on Open Multimedia Architecture Platform (OMAP) embedded system. A high-impedance active dry electrode was tested for improving the scalp- electrode interface. It was used the sigma-delta ADS1298 analog-to-digital converter, and developed a “kernelspace” character driver to manage the communications between the converter unit and the OMAP’s ARM core....
Cognitive intervention protocol for age-related memory impairments
Portugal, Ana Maria; Ferreira, Daniela Silva; Reis, Joana Santos; Pinho, Francisco; Dias, Nuno S.With the number of elderly people increasing tremendously worldwide, comes the need for effective methods to maintain or improve older adults' cognitive performance. Using continuous neurofeedback, through the use of EEG techniques, people can learn how to train and alter their brain electrical activity. A software platform that puts together the proposed rehabilitation methodology has been developed: a digital...
Uma análise sócio-semiótica do Via Catarina
Pinho, FranciscoThe mall’s genesis is based on a chain of changes, which took place on the length of time that came after the Industrial Revolution. For their importance, the individual’s assertment; the large increase of the production and, finally, the constant branching of the urbane space, are pointed out. We live in a society of codes and themes, which despite being unwritten, are previously understood as producers of mea...
Cytotoxic and genotoxic effects of cadmium in human osteoblasts
Pinho, Francisco Carvalho VieiraDue to industrialization, cadmium has been increasingly accumulated in soil, water and air, and consequently the food chain, thus, being responsible for many diseases. In humans, damages to several organs and carcinogenic effects take place. However, the mechanisms underlying the bone diseases remain unknown, and so, this work aims to evaluate cytotoxic and genotoxic effects of cadmium in human osteoblasts cell...
Diferenças entre os depósitos auríferos do Grupo Aguapei (Estado de Mato Grosso...
Fernandes, Carlos Jose; Pulz, Genova Maria; Kuyumjian, Raul Minas; Pinho, Francisco Egidio CavalcanteGold prospects in the Aguapeí Folded Belt are situated in the southwestern portion of the Amazon Craton, within the Alto Guaporé Province, southwestern state of Mato Grosso. The mineralizations are mainly concentrated in the Pau-a-Pique Deposit (south), Lavrinha Region (central), and São Vicente Mine (north). Gold ore comprises quartz veins and disseminations in the low-grade metamorphic metassedimentary rocks ...
