A flexible bio-inspired hierarchical model for analyzing musical timbre
(2016)A flexible and multipurpose bio-inspired hierarchical model for analyzing musical timbre is presented in this paper. Inspired by findings in the fields of neuroscience, computational neuroscience, and psychoacoustics, not ... -
Experimental study of dynamic bending stiffness of ACSR overhead conductors
(2015)Abstract : Aeolian vibrations of transmission line conductors may cause fretting fatigue failure at or near the location of clamped devices. At these locations, the bending stiffness variation of the conductor has a large ... -
Strengthening of the net section of steel elements under tensile loads with bonded CFRP strips
(2014)Abstract : The use of CFRP is increasingly common as a solution for the strengthening of structures, but the majority of research and applications have focused on the retrofit of concrete structures. The application of ... -
Experimental investigation of multi-material aluminum-to-steel and GFRP-to-steel bonded and bolted/bonded connections
(2016)Abstract : Through an experimental study, this paper describes the behavior of single-lap bonded, bolted and bolted/bonded connections for configurations with minimum geometric parameters proposed in design references. Two ... -
Effect of geometric parameters on the behavior of bolted GFRP pultruded plates
(2016)Abstract : This paper presents the effect of geometric parameters on the behavior of bolted GFRP pultruded plates for civil engineering applications. After a literature review, results of an experimental analysis investigating ... -
Effect of geometrical parameters of aluminum-to-steel bolted connections
(2015)Abstract : Through experimental and numerical studies, this research work aims to provide directions on the optimal geometric configuration for single-lap and double-lap bolted connection between aluminum alloy 6061-T6 and ... -
Network-selectivity and stimulus-discrimination in the primary visual cortex : cell-assembly dynamics
(2015)Abstract : Visual neurons coordinate their responses in relation to the stimulus; however, the complex interplay between a stimulus and the functional dynamics of an assembly still eludes neuroscientists. To this aim, ... -
Stimulus-dependant augmented gamma oscillatory activity between the functionally connected cortical neurons in V1
Other titre : Stimulus-dependent augmented gamma oscillatory activity between the functionally connected cortical neurons in the primary visual cortex(2015)Abstract : Neuronal assemblies typically synchronize within the gamma band (30-80 Hz) and are fundamental to information processing. Despite numerous investigations, the exact mechanisms and origins of gamma oscillations ... -
Reprogramming of orientation columns in visual cortex : a domino effect
(2015)Abstract : Cortical organization rests upon the fundamental principle that neurons sharing similar properties are co-located. In the visual cortex, neurons are organized into orientation columns. In a column, most neurons ... -
High noise correlation between the functionally connected neurons in emergent V1 microcircuits
(2016)Abstract : Neural correlations (noise correlations and cross-correlograms) are widely studied to infer functional connectivity between neurons. High noise correlations (Rsc) between neurons have been reported to increase ... -
Summation of connectivity strengths in the visual cortex reveals stability of neuronal microcircuits after plasticity
(2015)Abstract : Background: Within sensory systems, neurons are continuously affected by environmental stimulation. Recently, we showed that, on cell-pair basis, visual adaptation modulates the connectivity strength between ... -
Brain at work : time, sparseness and superposition principles
(2012)Abstract : Many studies explored mechanisms through which the brain encodes sensory inputs allowing a coherent behavior. The brain could identify stimuli via a hierarchical stream of activity leading to a cardinal neuron ... -
A parallel supercomputer implementation of a biological inspired neural network and its use for pattern recognition
(2012)Abstract : A parallel implementation of a large spiking neural network is proposed and evaluated. The neural network implements the binding by synchrony process using the Oscillatory Dynamic Link Matcher (ODLM). Scalability, ... -
Source separation with one ear : proposition for an anthropomorphic approach
(2005)Abstract : We present an example of an anthropomorphic approach, in which auditory-based cues are combined with temporal correlation to implement a source separation system. The auditory features are based on spectral ... -
Adaptation-induced plasticity and spike-waveforms in cat visual cortex
(2012)Abstract : Orientation-selective neurons shift their preferred orientation after being adapted to a nonpreferred orientation. These shifts of the peaks of tuning curves may be in the attractive or repulsive direction in ... -
Performance of three acoustical methods for localizing whales in the Saguenay - St. Lawrence Marine Park
(2008)Abstract : Three algorithms are explored to localize fin whale calls recorded from a large-aperture hydrophone array deployed in the Saguenay—St. Lawrence Marine Park. The methods have to cope with varying sound speed in ... -
Wavelet speech enhancement based on time-scale adaptation
(2006)Abstract : We propose a new speech enhancement method based on time and scale adaptation of wavelet thresholds. The time dependency is introduced by approximating the Teager Energy of the wavelet coefficients, while the ... -
Sensorial substitution system with encoding of visual objects into sounds
(2011)Abstract : Visual and auditory prostheses involve surgeries that are complex, expensive, and invasive. They are limited to a small number of electrodes and can only be used when the impairment is peripheral. The Vibe and ... -
Audiovisual correspondence between musical timbre and visual shapes
(2014)Abstract : This article investigates the cross-modal correspondences between musical timbre and shapes. Previously, such features as pitch, loudness, light intensity, visual size, and color characteristics have mostly been ... -
Wavelet noise reduction : application to speech enhancement
(2000)Abstract : During the past decade, the Wavelet Transforms (WT) have been applied to various research areas. Their applications include signal and image denoising, compression, detection, and pattern recognition. To our ...
