A deep learning approach for segmentation of red blood cell images and malaria detection
(2020-06-13)
Article
Open AccessMalaria is an endemic life-threating disease caused by the unicellular protozoan parasites of the genus Plasmodium. Confirming the presence of parasites early in all malaria cases ensures species-specific antimalarial ... -
A deep learning pproach for the morphological recognition of reactive lymphocytes in patients with COVID-19 infection
(2022-05-23)
Article
Open AccessLaboratory medicine plays a fundamental role in the detection, diagnosis and management of COVID-19 infection. Recent observations of the morphology of cells circulating in blood found the presence of particular reactive ... -
A design procedure for overlapped guaranteed cost controllers
(Elsevier, 2008)
Conference lecture
Open AccessIn this paper a quadratic guaranteed cost control problem for a class of linear continuous-time state-delay systems with norm-bounded uncertainties is considered. We will suppose that the systems are composed by two ... -

A fault detection method for pitch actuators faults in wind turbines
(2015)
Conference report
Open AccessThe paper presents a model-based fault detection method for pitch actuators faults using the normalized gradient method to estimate the parameters of the pitch actuator. One major difficulty is that the input signal to the ... -
A hybrid approach of knowledge-based reasoning for structural assessment
(2005-11)
Article
Restricted access - publisher's policyA hybrid reasoning system is developed for damage assessment of structures. The system combines the use of a model of the structure with a knowledge-based reasoning scheme to evaluate if damage is present, its severity ... -
A Hysteresis dynamic mathematical model approach to parametric estimation system
(Hindawi, 2021-02-14)
Article
Open AccessThe main contribution of this paper is the proposal of a recent hysteresis dynamic model which is successfully employed within a posited signal modulator. The modulation of signals is a commonly required stage in many ... -
A mathematical framework for structural control integration
(Trans Tech Publications, 2012)
Conference report
Open AccessIn this paper, some control strategies to design decentralized controllers are developed and discussed. These strategies are based on the Inclusion Principle, a very useful mathematical framework to obtain decentralized ... -
A nonlinear damping control for the vibration mitigation of the benchmark highway bridge
(2009-08)
Article
Open AccessActive, passive and semi-active controls have been extensively considered to improve the protection of structures against earthquakes. In this paper, we present a new nonlinear damper, which is then applied to a three-dimensional ... -
A review of impact damage detection in structures using strain data
(2010)
Article
Open AccessThis paper aims to provide a state-of-the-art review on impact damage detection techniques in structures using strain data. An overview of impact detection systems is provided. These include sensors, specimens, and impact ... -
A robust procedure for Damage detection from strain measurements based on Principal Component Analysis
(2013-04-17)
Article
Restricted access - publisher's policyFBGs are excellent strain sensors, because of its low size and multiplexing capability. Tens to hundred of sensors may be embedded into a s tructure, as it has already been demonstrated. Nevertheless, they only afford ... -
A velocity-based seismic control for base-isolated building structures
(American Automatic Control Council, 2009-06-10)
Conference report
Open AccessPassive, active and semi-active control have been extensively considered to improve the protection of base-isolated structures against earthquakes. This paper presents a strategy to apply control forces to the base of an ... -
Acceleration-based fault-tolerant control design of offshore fixed wind turbines
(2016)
Article
Open AccessWind turbines (WTs) are basically controlled by varying the generator load torque (with the so-called torque control) and the blade pitch angles (with the so-called pitch control) based on measurement of the generator shaft ... -
Active piezoelectric system using PCA
(2010)
Conference report
Restricted access - publisher's policyIn previous work by the authors, an aircraft turbine blade was used to show that T and Q-statistics formulation based in Principal Components Analysis (PCA) are successful indices to detect and distinguish damages. In ... -
Active-passive control strategy for adjacent buildings
(2011)
Conference lecture
Open AccessIn this paper, a control strategy to mitigate the vibrational response of adjacent buildings under seismic excitation is presented. The proposed strategy combines interbuilding passive actuators with active actuators ... -
Active-passive decentralized H-infinity control for adjacent buildings under seismic excitation
(2011)
Conference lecture
