Auditory brainstem responses were measured in five normal-hearing subjects, using single-cycle sinusoids at octave frequencies ranging from 250 to 2000 Hz. These sinusoids, gated with Blackman functions, were presented either at 0 or 180 degree phase and were varied in level from 90 dB SPL to threshold in 10-dB steps. Stimulus phase affected wave V latencies for low-frequency stimuli, with the ...

In many practical applications, it turned out to be efficient to assume that the signal or an image is sparse, i.e., that when we decompose it into appropriate basic functions (e.g., sinusoids or wavelets), most of the coefficients in this decomposition will be zeros. At present, the empirical efficiency of sparsity-based techniques remains somewhat a mystery. In this paper, we show that fuzzy-...

In this work, an experimental technique is applied for the measurements of the vibrations and deformation of a test transformer core. Since the grid voltage contains some higher harmonics, in addition to a purely sinusoidal magnetisation of the core the presence of third harmonic is also studied. The vibrations of the transformer core for points as well as the surface scan of the leg show more ...

This paper presents the timbre model, a signal model which has been built to better understand the relationship between the perception of timbre and the musical sounds most commonly associated with timbre. In addition, an extension to the timbre model incorporating expressions is introduced. The presented work therefore has relation to a large field of science, including auditory perception, si...

Although sinusoidal models have been shown to be useful for timescale and pitch modiication of voiced speech, objectionable artifacts often arise when such models are applied to unvoiced speech. This correspondence presents a sinusoidal model-based speech modiication algorithm that preserves the natural character of unvoiced speech sounds after pitch and timescale modiication, eliminating commo...

the basic model for valuation of firm is the dividend discount model (ddm). when investors buy stocks, they expect to receive two types of cash flow: dividend in the period during which the stock is owned, and the expected sales price at the end of the period. in the extreme example, the investor keeps the stock until the company is liquidated; in such a case, the liquidating dividend becomes t...

Long-range channel prediction is considered to be one of the most important enabling technologies to future wireless communication systems. The prediction of Rayleigh fading channels is studied in the frame of sinusoidal modeling in this paper. A stochastic sinusoidal model to represent a Rayleigh fading channel is proposed. Three different predictors based on the statistical sinusoidal model a...

Researchers have developedmanymodels to simulate the elasto-plastic contact of spheres. However, there does not appear to exist a closed-form analytical model for elasto-plastic three-dimensional sinusoidal contact. This work uses a finite element model (FEM) to characterize elasto-plastic sinusoidal contact. Although at initial contact the sphere and sinusoidal case are very similar and can bo...

This paper proposes a fractal sinusoidal model that is able to reduce the bit-rate of sinusoidal model coders while achieving perceptually lossless quality. This is achieved by removing the redundancy between sinusoidal tracks through encoding similar tracks with the transformation between a template track and the original track. This paper proposes a transform that is able to capture the perce...
