Multi-planet extrasolar systems - detection and dynamics
(NATL ASTRONOMICAL OBSERVATORIES, CHIN ACAD SCIENCESBEIJING, 2012)
20 years after the discovery of the first planets outside our solar system, the current exoplanetary population includes more than 700 confirmed planets around main sequence stars. Approximately 50% belong to multiple-planet ...
A New Multi-filter Framework with Statistical Dense SIFT Descriptor for Spoofing Detection in Fingerprint Authentication Systems
(2021-01-01)
Fingerprint-based authentication systems represent what is most common in biometric authentication systems. Today’s simplest tasks, such as unlocking functions on a personal cell phone, may require its owner’s fingerprint. ...
Desenvolvimento de um inversor fotovoltaico modular de fases reconfiguráveis
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2021-10-01)
This Master’s Thesis presents the development of a modular photovoltaic inverter with reconfigurable
phases. A power module to compose a modular photovoltaic inverter is proposed with

Modeling the electric degradation of podocytes and detection of albumin for the early diagnostics of the glomerulus's damage
(Institute of Electrical and Electronics Engineers Inc., 2017-05)
In this paper, the pass of proteins like the albumin through the glomerular layers is modeled. Mainly, we have focused on the mathematical model based on physics which might explain the filtering of giant proteins like the ...
Design of reflectivity-based surface plasmon resonance optical sensors for ultrasound detection
(Taylor & Francis Ltd, 2021-06)
Sensors based on surface plasmon resonance present attractive features for the detection of narrow acoustic pulses since they can behave as quasi-point detectors. In order to detect fast ultrasound pressure waves, the ...
A PZT-based technique for SHM using the coherence function
(2011-06-13)
This paper presents a new approach for damage detection in structural health monitoring systems exploiting the coherence function between the signals from PZT (Lead Zirconate Titanate) transducers bonded to a host structure. ...

Evaluation of EDXRF configurations to improve the limit of detection and exposure for in vivo quantification of gadolinium in tumor tissue
(Pergamon-Elsevier Science Ltd, 2016-05)
In this paper the configuration of an Energy Dispersive X-Ray Fluorescence (EDXRF) system optimized for in vivo quantification of gadolinium in tumor tissue was studied. The system was configured using XMI-MSIM software ...
Experimental observatións of pulsed capillary discharges
(2015)
In this thesis we present experimental results obtained with two configurations of a low stored energy fast capillary discharge. In one configuration a smooth, continuous capillary was used and in the other a novel segmented ...
