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...

introduction: auditory temporal resolution and auditory temporal ordering are two major components of the auditory temporal processing abilities that contribute to speech perception and language development. auditory temporal resolution and auditory temporal ordering can be evaluated by gap-in-noise (gin) and pitch-pattern-sequence (pps) tests, respectively. in this survey, the effect of biling...

background: the success of dental implants depends on the manner in which stresses are transferred to the surrounding bone. an important consideration is to design an implant with a geometry that will minimize the peak bone stresses caused by standard loading. the aim of this study was to assess the infl uence of implant thread geometry on biomechanical load transfer and to compare the differen...

Spectutils is a GNU Octave toolkit for analyzing and visualizing audio signals. Spectutils allows to display oscillograms, FFT spectrograms as well as pitch detection graphs. Spectutils can best be characterized as a user interface for GNU Octave, which integrates signal analysis and visualization functionality into dedicated function calls. Therefore, signal analysis with Spectutils requires l...

The aim of the present work is to perform a step towards more natural pitch shifting techniques in singing voice for its application in music production and entertainment systems. In this paper, we present an advanced method to achieve natural modifications when applying a pitch shifting process to singing voice by modifying the spectral envelope of the audio excerpt. To this end, an all-pole m...

In this paper, we present a novel melody representation and matching method, which is both robust against pitch errors and invariant to liner or non-linear tempo variation. The melody of a music item or a query is represented by a point sequence, which is derived from the pitch contour of the melody. This point sequence is invariant to the time or speed in the original melody contour. Important...

Because of fluctuation in leg tension, pitch motion is very effective fatigue and life safety of leg elements in tension leg structures (TLSs). In this paper an exact solution for pitch vibration of a TLS interacting with ocean wave is presented. The legs of TLP are considered as elastic springs. The flow is assumed to be irrotational and single-valued velocity potentials are defined. The effec...

We manually designed rules for a backchannel (BC) prediction model based on pitch and pause information. In short, the model predicts a BC when there is a pause of a certain length that is preceded by a falling or rising pitch. This model was validated against the Dutch IFADV Corpus in a corpus-based evaluation method. The results showed that our model performs slightly better than another well...
