A perceptually-motivated low-complexity instantaneous linearchannel normalization technique applied to speaker verification
(Elsevier, 2015)
This paper proposes a new set of speech features called Locally-Normalized Cepstral Coefficients (LNCC) that are based onSeneff’s Generalized Synchrony Detector (GSD). First, an analysis of the GSD frequency response is ...
Deep Recurrent Learning for Heart Sounds Segmentation based on Instantaneous Frequency FeaturesAprendizaje profundo y recurrente para la segmentación de sonidos cardíacos basado en características de frecuencia instantánea
(Universidad de Buenos Aires. Facultad de Ingeniería. Departamento de Electrónica, 2020-10)
In this work, a novel stack of well-known technologies is presented to determine an automatic method to segment the heart sounds in a phonocardiogram (PCG). We will show a deep recurrent neural network (DRNN) capable of ...
Molting behavior and growth in the giant barnacle austromegabalanus psittacus (molina, 1782)
(UNIV VALPARAISO, 2008)
The effect of temperature and photoperiod on molt production in juvenile specimens of the acorn barnacle Austromegabalanus psittacus (Molina, 1782) was evaluated under controlled conditions. Growth was determined both under ...
Global atmospheric dynamics investigated by using Hilbert Frequency Analysis
(MDPI, 2016)
The Hilbert transform is a well-known tool of time series analysis that has been widely used to investigate oscillatory signals that resemble a noisy periodic oscillation, because it allows instantaneous phase and frequency ...
Uso de modulação de fase instantânea para formação de imagens por ultrassom usando ondas de Lamb
(Universidade Estadual Paulista (Unesp), 2020-09-04)
A formação de imagens de placas usando arrays ultrassônicos e ondas de Lamb é um tópico de interesse em muitas áreas industriais, tais como o aeronáutico, automotivo e do petróleo. Técnicas utilizando operações delay and ...
Using multiple frequency bins for stabilization of FD-ICA algorithms
(Elsevier Science, 2016-02)
In the frequency domain independent component analysis approaches for audiosources separation, the convolutive mixing problem is replaced by thesolution of several instantaneous mixing problems, one for each frequencybin ...
Time-variant modal parameters and response behavior of a base-isolated building tested on a shake table
(Earthquake Engineering Research Institute, 2018)
This paper presents the identification of the instantaneous modal properties
and the experimental response of a full-scale, five-story base-isolated RC building tested on a shake table. A suite of earthquake motions of ...
