Optimal Frequency Range Selection for PZT Transducers in Impedance-Based SHM Systems
(Institute of Electrical and Electronics Engineers (IEEE), 2010-08-01)
Piezoelectric transducers of PZT (lead zirconate titanate) have been widely used in structural health monitoring (SHM) systems based on the electromechanical (E/M) impedance technique. In this technique, damages in the ...

Modulation of frequency preference in heterogeneous populations of theta-resonant neurons
(Pergamon-Elsevier, 2020)
Neurons from several brain regions resonate in the theta frequency range (4-12 Hz), displaying a higher voltage response to oscillatory currents at a preferred 'resonant' frequency (f(R)). Subthreshold resonance could ...
Practical framework for frequency stability studies in power systems with renewable energy sources
(IEEE-Inst Electrical Electronics Engineers, 2020)
The transition from power systems dominated by synchronous machines to systems based on converter-based generation technologies (CGTs), is weakening currently robust power systems by reducing system inertia with the ...
Patterns of phenotypic selection for oil and nectar in Monttea aphylla (Plantaginaceae) in a geographic mosaic of interactions with pollinators
(Elsevier Gmbh, 2017-07)
Oil-flower species are highly specialized attracting a narrow group of oil-collecting bees in contrast to nectar-flower species visited by a wide diversity of pollinators. The vast majority of the oil species lack nectar ...
Neuronal resonance in the theta (4-10 hz) frequency range is modulated by dynamic changes in the input resistance
(2017)
Most neurons of the mammalian brain display intrinsic resonance with frequency selectivity (fR) for inputs within the theta-range (4-10 Hz). Variations in network oscillation along this range depend on the animal behavior; ...
Electrical resonance in the θ frequency range in olfactory amygdala neurons
(Public Library of Science, 2014)
The cortical amygdala receives direct olfactory inputs and is thought to participate in processing and learning of biologically relevant olfactory cues. As for other brain structures implicated in learning, the principal ...
Parâmetros genéticos da concentração de ferro e de zinco em sementes de feijão andino
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2015-02-23)
The aim of this work was to investigate if occurs maternal effect for iron and zinc concentrations in Andean bean seeds, to obtain genetic parameters estimates for these minerals, and to select recombinants for the bean ...
Electrical resonance in the h frequency range in olfactory amygdala neurons
(PLOS One, 2014)
The cortical amygdala receives direct olfactory inputs and is thought to participate in processing and learning of biologically
relevant olfactory cues. As for other brain structures implicated in learning, the principal ...
