Although sinusoidal models have been demonstrated to be capable of high-quality musical instrument synthesis [1], speech modi cation [2], and speech synthesis [3], little exploration of the application of these models to the synthesis of singing voice has been undertaken. In this paper, we propose a system framework similar to that employed in concatenation-based text-to-speech synthesizers, an...

The development and motion of fronts associated with lee-side troughs on large mountain barriers has been investigated. These fronts differ from ordinary cold fronts in their horizontal temperature field, which is characterized by a sinusoidal thermal ridge. The thermal ridge intensifies, while remaining stationary with respect to the mountains, and moves eastward upon the approach of a Pacific...

To calculate the pressure pulsations in pipelines in frequency domain, it is necessary to linearize the nonlinear damping function jqjq, under the condition that the flow q is periodic, but not sinusoidal. The authors have proposed an idea that two equivalent linearization coefficients should be determined in such cases. To verify the idea, the responses of pressure pulsation in a simple pipeli...

The flow-resistive characteristics of a variety of commercially available expiratory positive-pressure valve systems used to provide continuous positive airway pressure (CPAP) and positive end-expiratory pressure were evaluated. One flow-resistor and seven threshold-resistor expiratory pressure valve systems were set at 5, 10, 15, 20, and 25 cm H2O of expiratory pressure, and sinusoidal exhaled...

The presence of amplitude fluctuations in one frequency region can interfere with our ability to detect similar fluctuations in another (remote) frequency region. This effect is known as modulation detection interference (MDI). Gating the interfering and target sounds asynchronously is known to lead to a reduction in MDI, presumably because the two sounds become perceptually segregated. The fir...

The pneumatic pressure control systems have been used in some fields. However, the researches on pneumatic pressure control mainly focus on constant pressure regulation. Poor dynamic characteristics and strong nonlinearity of such systems limit its application in the field of pressure tracking control. In order to meet the demand of generating dynamic pressure signal in the application of the h...

A comparative electron microscopic study was made on the effects of saponin on the sinusoids and capillaries of various organs of rabbits and the sinusoids of the bone marrow in cats, dogs, rats and mice. Animals received an intravenous injection of saponin at a dose of 2 mg per kg of body weight and were sacrificed 6 hours after injection. In rabbits, the sinusoidal endothelium of the bone mar...

The study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. Therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave forces on the structures body in different boundary conditions. In this study, the propagation of static ...
