Some features of the acceleration impulse response function
(2021-01-01)
Impulse response functions (IRFs) and frequency response functions (FRFs) are fundamental quantities that describe the dynamic behaviour of a linear vibrating system in the time and frequency domains respectively. The ...
Methodological approach for defining frequency related grid requirements in low-carbon power systems
(IEEE, 2020)
Moving towards low-carbon electricity systems through the massive deployment of
renewable energy sources (RES) presents a unique opportunity to combat climate change, but it also poses
enormous technical challenges, ...
Functional differences of low- and high-frequency oscillatory dynamics during illusory border perception
(ELSEVIER, 2010)
Neuronal oscillations are an essential part of several brain processes like perception, memory and attention, but little is known about the simultaneous dynamics of different frequency bands in such processes. Here, we ...
Determinación de la Respuesta Dinámica y Estacionaria de la Frecuencia frente a Desbalances de Potencia Producidos por Perturbaciones en la Red
(CENACE, 2016-01)
This paper proposes a new methodology for determining the transient and steady state frequency deviations produced by disturbances in the power system that modify the generation-load balance. Based on the equivalent frequency ...
Frequency tuning of mechanical responses in the mammalian cochlea
(1996)
The search for mechanisms responsible for the high sensitivity and sharp frequency tuning of first-order auditory neurons has produced surprising results. The cochlea, the mammalian auditory receptor, responds to acoustic ...
Fault Interpretation Algorithm Using Frequency-Response Analysis of Power Transformers
(Institute of Electrical and Electronics Engineers, 2016-06)
Sweep frequency-response analysis (SFRA) is a powerful technique to detect mechanical damage in transformer windings, such as deformations and displacements, as well as other failures, helping to prevent severe damage. ...
Design and implementation of a body coupled communication system for streaming music
(IEEE, 2017)
Thanks to the revolution in electronics and telecommunications, there is a proliferation of devices for medical applications and others operating in the body area. There is a novel way to connect two transceivers with the ...
Frequency response envelopes of a family of uncertain discrete-time systems
(Birkhauser Boston IncCambridgeEUA, 2003)
A contribution for nonlinear structural dynamics characterization of cantilever beams
(2005-12-01)
Successful experiments in nonlinear vibrations have been carried out with cantilever beams under harmonic base excitation. A flexible slender cantilever has been chosen as a convenient structure to exhibit modal interactions, ...
