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: habitual pitch perception associated with the mean fundamental frequency of speech. In the clinical evaluation referred to this issue is dealt with in the normal range for a person whether he is a habitual pitch. A common feature in many of the abnormal pitch of voice disorders, the assessment of habitual pitch and factors affecting it, may help scientists to determine the exist...
AbstractThe Darrieus turbine is used as an ocean current converter to generate renewable electrical energy. One way improve performance determine the optimal pitch angle. Therefore, purpose of this study was angle NACA 0018 airfoil with variations -6°, -2°, 0° and 2°. Numerical method help Ansy Fluent software carried out for construction turbine. The result research that 2° produces largest co...
When we speak, can vary how use our voices. Our speech be high or low (pitch), loud soft (loudness), and fast slow (duration). This variation in pitch, loudness, duration is called prosody. It a bit like making music. Varying voices when speak express sarcasm emotion even change the meaning of what are saying. So, prosody crucial part spoken language. But do speakers produce prosody? How listen...
Good alignment of the magnetic field line pitch angle with the mode structure of an external resonant magnetic perturbation (RMP) field is shown to induce modulation of the pedestal electron pressure p(e) in high confinement high rotation plasmas at the DIII-D tokamak with a shape similar to ITER, the next step tokamak experiment. This is caused by an edge safety factor q95 resonant enhancement...
This paper proposes a fundamental frequency tracker, with the specific purpose of comparing the automatic estimates with pitch contours that are sketched by trained phoneticians. The method uses a frequency domain approach to estimate pitch tracks that form minimum jerk trajectories. This method tries to mimic motor movements of the hand made while sketching. When the fundamental frequency trac...
Implicit, abstract knowledge acquired through language experience can alter cortical processing of complex auditory signals. To isolate prelexical processing of linguistic tones (i.e., pitch variations that convey part of word meaning), a novel design was used in which hybrid stimuli were created by superimposing Thai tones onto Chinese syllables (tonal chimeras) and Chinese tones onto the same...
Handling pose variations for face recognition system is a challenging task. The recognition rate is drastically decreasing with the images captured in uncontrolled environment having pose variations in yaw, pitch and roll angles. When the face image with frontal pose it is proved that the recognition system performs well. In this research an attempt is made to reconstruct frontal pose face imag...
This study is aimed to investigate the extent to which reporters’ voice and body behaviour may betray different degrees of emotional involvement when reporting on emergency situations. The hypothesis is that emotional involvement is associated with an increase in body movements and pitch and intensity variation. The object of investigation is a corpus of 21 10-second videos of Italian news repo...
The paper treats a question of proportional-integral-derivative (PID) controller design for aircraft pitch attitude in the presence of uncertain aerodynamics. The presented design methodology guarantees desired pitch attitude transient performance indices by inducing of two-time-scale motions in the closed-loop system where the controller dynamics is a singular perturbation with respect to the ...
