Accurate neural coding of the pitch of complex sounds is an essential part of auditory scene analysis; differences in pitch help segregate concurrent sounds, while similarities in pitch can help group sounds from a common source. In quiet, nonreverberant backgrounds, pitch can be derived from timing information in broadband high-frequency auditory channels and/or from frequency and timing infor...

in this study, the roll, yaw and depth fuzzy control of an au- tonomous underwater vehicle (auv) are addressed. yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. the discussed auv has four aps at the rear of the vehicle as actuators. two rule bases...

Although horizontal binocular retinal disparity between images in the two eyes resulting from their different views of the world has long been the centerpiece for understanding the unique characteristics of stereovision, it does not suffice to explain many binocular phenomena. Binocular depth contrast (BDC), the induction of an appearance of visual pitch in a centrally located line by pitched-f...

Employment of highly integrated ASIC front-end electronics in GSI and FAIR detector systems is crucial in view of current and future detector granularity, overall channel number and radiation length to be minimized. Yet, integration of such multi-channel readout chips into detectors brings a severe technological gap up to light, where channel pitch on silicon is found on the order of 50 μm, whe...

Abstract – Multipitch tracking in real environments is critical for speech signal processing. Determining pitch in reverberant and noisy speech is a particularly challenging task. In this paper, we propose a robust algorithm for multipitch tracking in the presence of both background noise and room reverberation. An auditory front-end and a new channel selection method are utilized to extract pe...

We investigate a longitudinally loaded elastic nanorod inside a cylindrical channel and show within the context of classical elasticity theory that the Euler buckling instability leads to a helical postbuckling form of the rod within the channel. The local pitch of the confined helix changes along the channel and so does the longitudinal force transmitted along the rod, diminishing away from th...

This paper presents a new extended average magnitude difference function for noise robust pitch detection. Average magnitude difference function based algorithms are suitable for real time operations, but suffer from incorrect pitch detection in noisy conditions. The proposed new extended average magnitude difference function involves in sufficient number of averaging for all lag values compare...

Attitudinally-varied back channel utterances were simulated by six professional voice actors for Japanese. Contrary to the general assumption that a pitch accent language like Japanese cannot vary the tonal configuration for attitudinal variation as in a stress/intonation language, all the speakers differentiated two kinds of tonal configurations. Further variation was achieved by phrasing utte...
