Two experiments were performed to investigate subjects' ability to detect and discriminate 50-ms up-glides in frequency in several different conditions. In the first experiment, the subjects indicated which of two signals increased more in pitch. The comparison, or standard signal, was a sinusoid which increased in frequency by either 0, 250, or 500 Hz. Center frequencies were 0.5, 1, 2, 4, and...

A least-square infinite series approximation (L-SISA) technique is proposed for modeling amplitude modulated (AM) sinusoidal components of naturally occurring signals, such as those produced by traditional musical instruments. Each AM sinusoid is iteratively extracted using an analysis-by-synthesis technique and the problem of parameter estimation is linearised for least-square approximation th...

We present here an Harmonic+Noise Model (HNM) for speech synthesis. The noise part is represented by an autoregressive model whose output is pitchsynchronously modulated in energy. The harmonic part of the signal is represented by a sinusoidal model. This paper compares di erent methods for separating these two components. We then propose a method for the estimation of the sinusoidal parameters...

Interfacial mechanical properties of carbon/glass hybrid thermoplastic epoxy composite rods play a crucial role in the determination strength and fracture behavior. In this study, push-out push-back tests using three with different ratios were performed to investigate interfacial shear mechanism. Debonding occurred at interface between glass fiber bundles epoxy. After onset debonding, sinusoida...

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 ...

Abstract Plenty of research on elastic interfaces has been done systems where the interface is pushed with a constant force. We studied average velocity an under sinusoidal driving in creep region, considering both short-range systems, such as magnetic domain walls during hysteresis loop, and long-ranged fractures. obtained modified version approximate power-law behavior material-dependent expo...

Recent progresses in liquid phase crystallization enabled the fabrication of thin wafer quality crystalline silicon layers on low-cost glass substrates enabling conversion efficiencies up to 12.1%. Because of its indirect band gap, a thin silicon absorber layer demands for efficient measures for light management. However, the combination of high quality crystalline silicon and light trapping st...

A two-dimensional heat conduction problem in which a liquid becomes solidified by heat transfer to a sinusoidal mold of finite thickness is solved by using a linear perturbation method. The liquid perfectly wets the sinusoidal mold surface prior to the beginning of solidification. This leads to a corresponding undulation of the solidified shell thickness. Both surfaces of the mold follow a sinu...

In this paper, the performance of the recently proposed adaptive signal models on modeling speech voiceless stop sounds is presented. Stop sounds are transient parts of speech that are highly non-stationary in time. State-of-the-art sinusoidal models fail to model them accurately and efficiently, thus introducing an artifact known as the pre-echo effect. The adaptive QHM and the extended adapti...
