Although musical skills clearly improve with training, pitch processing has generally been believed to be biologically determined by the behavior of brain stem neural mechanisms. Two main classes of pitch models have emerged over the last 50 years. Harmonic template models have been used to explain cross-channel integration of frequency information, and waveform periodicity models have been use...

bubble columns are gas- liquid contactors that are widely used in chemical and bio- chemical industries. high mixing that result in high heat and mass transfer rates are amongst their advantages. heat transfer in a bubble column having a bundle of heaters investigated and the variation of heat transfer coefficient with variation in heaters pitch to diameter ratios in a bundle of heaters reporte...

Under the condition of specific pulsed discharge parameters, mode conversion low-temperature plasma jet channel that originally propagates along a straight line will occur, forming three-dimensional helical channel. Unlike traditional wave discharge, there are no factors such as an external constant magnetic field destroys poloidal symmetry dielectric tube, and chiral direction streamer change ...

A multi-band summary correlogram (MBSC)-based pitch detection algorithm (PDA) is proposed. The PDA performs pitch estimation and voiced/unvoiced (V/UV) detection via novel signal processing schemes that are designed to enhance the MBSC’s peaks at the most likely pitch period. These peak-enhancement schemes include comb-filter channel-weighting to yield each individual subband’s summary correlog...

longevity of osseointegrated implants are intensely influenced by biomechanical factors. control of these factors prevents mechanical complications, which include fracture of screws, components, or materials veneering the framework. in this study, the impact of length and threads pitch of dental implants on the stress distribution and maximum von mises stress in implant-abutment complex and jaw...

Good listeners generally produce back-channel feedback, that is, short utterances such as uh-huh which signal active listening. As the rules governing back-channeling vary from language to language, second-language learners may need help acquiring this skill. This paper is an initial exploration of how to provide this. It presents a training sequence which enables learners to acquire a basic Ar...

SiC power MOSFETs have made great progress since the first commercial devices were introduced in 2011, but they are still far from their theoretical limits of performance. At blocking voltages above 1200 V specific on-resistance is limited by drift region, below resistance dominated channel and substrate, with smaller contributions source JFET regions. Trench cell area than planar DMOSFETs, inh...
