Detection and modulation rate discrimination were measured in cochlear-implant users for pulse-trains that were either sinusoidally amplitude modulated or were modulated with half-wave rectified sinusoids, which in acoustic hearing have been used to simulate the response to low-frequency temporal fine structure. In contrast to comparable results from acoustic hearing, modulation rate discrimina...

-The average density of randomly placed dots was modulated according to a spatial sinusoid and estimates were made of the signal/noise ratio (d’) of the sensory representation of the pattern from subjects’ responses. This was compared with the signal/noise ratio of the targets, and the results are expressed as the efficiency (F) with which the statistical information in the targets is utilized....

This experiment was an investigation of the ability of listeners to identify the constituents of double vowels (pairs of synthetic vowels, presented concurrently and binaurally). Three variables were manipulated: (1) the size of the difference in F0 between the constituents (0, 1/2, and 6 semitones); (2) the frequency relations among the sinusoids making up the constituents: harmonic, shifted (...

Many communicative behaviors in the animal kingdom consist of performing and recognizing specialized patterns of oscillatory motion. Here we present an approach to the representation and recognition of these oscillatory motions based on the categorical organization of a simple sinusoidal model having very specific and limited parameter values. This characterization is used to specify the types ...

Measuring thresholds for the detection of brief decrements in the level of a sinusoid is an established method of estimating auditory temporal resolution. Generally, a background noise is added to the stimulus to avoid the detection of the "spectral splatter" introduced by the decrement. Results are often described in terms of a temporal-window model, comprising a band-pass filter, a compressiv...

this study seeks to examine how a company can select the best intermediary for its marketing channels with minimum of criteria and time. a theoretical framework is proposed based on the most important tasks of intermediary and the criteria to measure them. there are four basic tasks and thirty criteria in three independent levels. subsequently, an exploratory case study in iranian food industry...

The 17th ISCHS took place in Osaka, Japan, on 23 to 25 September 2013. This symposium focuses on an exchange of views on the structure and function of hepatic sinusoidal cells in addition to their roles in clinical pathophysiology.

The main objective of current study is investigation on thermo-hydraulic behavior nanofluids in a sinusoidal wavy channel as novel geometry under influences thermophoresis and Brownian motion. Differential quadrature method optimal homotopy asymptotic scheme have been employed to solve the momentum, continuity, energy nanoparticle fraction equations. validity proposed approaches evaluated by co...
